1 Introduction

In January 1998, the ANSI-1361

TDMA community through the Universal WirelessCommunication Consortium (UWCC) and TIA TR45.3 evaluated and adopted EGPRS as a keypart of its high speed data evolution. Consequently, a large part of EGPRS was incorporated as"136 High Speed (136HS)" into the TDMA IMT-2000 proposal called "UWC-136". There weretwo key characteristics that 136HS allowed; data rates up to 384 kbps, and initial deployment inless than 1 MHz of spectrum. During the past year, the TDMA Community has studied how tofurther enhance 136HS such that it would be closer to ETSI-EGPRS to better facilitate globalroaming, while also keeping the desire for initial deployment in less than 1 MHz of spectrum. Theresult of this effort is the "COMPACT " proposal.

COMPACT can be deployed in as little as 600 kHz (+guard) of spectrum, and looks as a pureoverlay system to an existing ANSI-136 network. As such, COMPACT is independent of the ANSI-136 system, which facilitates roaming of EGPRS only mobile stations, as well as it allowsoperators to deploy different infrastructure vendors for their data solution from their voice network.

For operators, which are not as spectrally challenged, the TDMA Community also supports thedevelopment of ETSI-EGPRS, which is referred to as "EGPRS Classic", requiring 2.4 MHz of initial spectrum. The support of both COMPACT and EGPRS Classic under what is calledEGPRS-136 represents a powerful solution towards the convergence of GSM and ANSI-136systems worldwide.

2 ANSI-41 Circuit-Switched Connectivity

2.1 Tunneling of ANSI-136 Messages

Integration of GPRS with ANSI-136 is logically accomplished by the addition of the GPRSnetwork nodes SGSN and GGSN to the ANSI-41 circuit-switched network. Figure 1 shows theReference Model for the resulting network.

Figure 1: GPRS-136 Network Reference Model

The primary ANSI-41 network node visible to the SGSN is the Gateway/Serving MSC/VLR. Theinterface between the ANSI-41 MSC/VLR and the SGSN in the above model is the Gs interface.This interface is extended to include the tunneling of Non-GSM messages facility (See CR

A116r1 to GSM 03.60). This allows the tunneling of ANSI-136 signaling messages between theMS and the MSC/VLR. The tunneling of ANSI-136 signaling messages is performed transparentlythrough the SGSN, i.e.; the SGSN does not interpret the signaling messages exchanged betweenthe MS and the MSC/VLR. Between the SGSN and the MS, the signaling messages aretransported using the TOM (Tunneling of Messages) protocol layer. TOM is a protocol layer that

Figure 2: Signaling Plane MS - Gateway/Serving MSC/VLR

Mobile stations supporting both circuit and packet services (called Class-B136 mobile stations)perform location updates with the circuit system by tunneling the Registration message to theMSC/VLR as explained in section 2.1. When an incoming call arrives for a given MS, theGateway/Serving MSC/VLR associated with the latest Registration, pages the MS through the

SGSN. The page can be a Hard page (circuit voice page without any additional parameters), inwhich case, the Gs interface paging procedures are used by the MSC/VLR and the SGSN. If thecircuit page is not for a voice call or, if additional parameters are associated with the page, aLayer 3 Page message is tunneled to the MS by the MSC/VLR. Upon receiving a page, themobile station suspends the packet-data traffic and leaves the packet-data channel for a suitableDigital Control Channel (DCCH). Broadcast information is provided on the packet control channelto assist the mobile station with a list of candidate DCCHs. Once on a DCCH, the mobile stationsends a Page Response. The remaining call setup procedures such as traffic channeldesignation, etc. proceed as in a normal page response situation.

2.2 30 kHz related BCCH Information

To facilitate seamless network operation between ANSI-136/ANSI-41 and EGPRS-136, someinformation related to ANSI-136 circuit operation needs to be broadcast on the BCCH or the

3 Air-Interface

3.1 EGPRS Classic Air-Interface Mode

The EGPRS Classic air-interface mode is identical to the core EGPRS concept [1].

EGPRS (i.e. EGPRS Classic) terminals on the 850 or 1900 MHz band will also support

COMPACT to facilitate roaming.

3.2 COMPACT Air-Interface Mode

See also [2], [3], [4], and [5] for more details.

3.2.1 Inter Base Station Synchronization3.2.1.1 Inter Base Station Time Synchronization

A key characteristic of COMPACT is that the base stations are time synchronized with eachother. This makes it possible to allocate common control channels in a way to preventtransmission/reception at the same time (see Section 3.2.2 ). This creates a higher effective reusenecessary for control signaling, e.g., 3/9 or 4/12.

The base station synchronization is carried out such that the following two requirements are

fulfilled:The time-slot structure is aligned between all sectors, i.e., TN0 occurs at the same time in allsectors.

The hyper-frame structures are aligned between all sectors, i.e., frame number 0 occurs atthe same time in all sectors.

Inter base station synchronization can be achieved by using GPS receivers, but other means arealso possible.

3.2.1.2 Inter Base Station Frequency Synchronization

Optionally, inter base station frequency synchronization can be implemented. This would allowthe frequency drift of the RF carriers to track each other, which in the following cases may easethe MS frequency-locking process to a COMPACT carrier:

Cell reselection when deploying inter base station frequency synchronization betweenCOMPACT base stations is deployed.

Cell selection based on pointers from ANSI-136 DCCH when inter base station frequency

synchronization between COMPACT and ANSI-136 base stations is deployed.

3.2.2 Time-Group Concept

f


8/36

4/12 reuse using all four time-groups

In Figure 3 , a 4/12 reuse is illustrated based on 3 carriers and 4 time-groups, where F x indicates

frequency x .To avoid adjacent channel interference from immediate neighbor sectors, it is advantageous toplan the time-groups such that none of neighbors are using the same time-group. As can be seenin Figure 3, this is possible when using 4 time-groups. When using 3 time-groups, however, thiscan not be achieved.

Time slot mapping of control channels is used. This ensures that the MS can see all neighbors inits normal measurement window. Consequently, the MS can measure on neighbor cellsbelonging to any time group, also during periods of continuous symmetric traffic, without any

need for traffic scheduling. (Note, traffic scheduling may still be deployed to ensure measurementopportunities in certain multi-slot configurations.)

The time slot mapping is carried out such that broadcast and common control channels of acertain time-group is rotating over the odd timeslot numbers as follows: 7, 5, 3, 1, 7, 5 This isillustrated in A. The actual rotation is carried out between frame 3 and 4 in the 52-multiframe.Note, it is only the CFCCH, CSCH, broadcast and common control channels that are rotating their timeslot position, i.e., the packet data traffic channels do not rotate their timeslot position.

Rotating time slot mapping of control channels also applies to control channels assigned toadditional carriers (see Section 3.2.6 ). A more detailed description of the timeslot structure anddivision of control and traffic is illustrated in A.

The CFCCH, CSCH, CPBCCH, CPCCCH, PDTCH, PACCH, and PTCCH are mapped as definedin Table 6 in C (based on an assignment of 1 CPBCCH and 3 CPCCCH blocks on all four timegroups in a multi-frame where N MOD 4 = 0).

The allocation of CPBCCH and CPCCCH to this new logical channel combination follows GSM05.02. This makes the allocation of the number of CPBCCH and CPCCCH flexible. The number of blocks allocated for CPBCCH 3 can vary between 1 and 4 and the number of blocks allocatedfor CPCCCH between 1 and 11. In this description, a CPCCCH block refers to a blocks that canbe used for paging .4 In addition to CPBCCH, these are the blocks that will have the higher effective reuse.

To secure a minimum number of measurement opportunities, the total number of blocks allocatedfor CPBCCH and CPCCCH must not be less than 4. For the same reason, all blocks allocated for CPBCCH and CPCCCH must be transmitted at full power by the base station.NOTE: See A for a complete description of Time Group 1, Time Group 2, Time Group 3, and

Time Group 4.

3.2.3.3 Secondary COMPACT Logical Channel Combinations

Additional carriers shall use one of the following logical channel combinations, of which the last isnew.

xiii) PDTCH+PACCH+PTCCHxxiii) CPCCCH+PDTCH+PACCH+PTCCH

In COMPACT, CPCCCH shall not be used in timeslot 0, 2, 4, or 6 on any carrier. Hence, a cellcan only use one PDCH for CPCCCH on each carrier.

3.2.3.4 CFCCH

Same as FCCH, but occurs in a different place (frame 25 as seen in A).3.2.3.5 CSCH

The CSCH serves the same functionality as the SCH. Since it occurs in different places within a


11/36

Using these new counters, the position of the CSCH in a hyper-frame is determined as:FN = (R1*51 + R2)*52 + 51

By knowing both the frame number as well as the time-group, the MS can deduce which time-slotthe CSCH was sent on and thereby resolve the control channel dynamic mapping during nextmulti-frame.

3.2.3.6 Discontinuous PTCCH

For COMPACT, the BTS shall employ discontinuous transmission (DTX) on the downlinkPTCCH. Specifically, if none of the timing advance fields (TAI=015) of a PTCCH downlinksignaling message (GSM 4.04) contain timing advance values then the downlink PTCCH burstscorresponding to this signaling message are not transmitted (masked).

3.2.4 USF

USF in COMPACT works as for regular EGPRS, i.e., the mobile relies on USF to schedule itsuplink transmissions. In COMPACT, there is however one special consideration due to therotation of time-slots for control channels.

On timeslots that carriers control (i.e. all odd timeslots on a carrier used for control), the USF inblock 0 should always be set to FREE. This eliminates any ambiguities what block 1 in uplink

should be used for after the rotation that occurs between block 0 and block 1.The allocation of CPRACH is dynamic, but in COMPACT the allocation should be prioritized toblocks immediately following CPBCCH or CPCCCH in downlink. Since USF controls thesucceeding uplink block, an idle downlink block will be followed by an idle uplink block. Hence,when other time-groups make downlink blocks idle to create the higher effective reuse for controlin the serving time-group, their succeeding uplink blocks will also be idle. Hence, uplink blocksimmediately following CPBCCH or CPCCCH in downlink will also enjoy a higher effective reuse.

3.2.5 Large Cell Operation

Several parameters in GSM confine the maximum cell size to approximately 35 km .5 Due to therequirement for inter-base station time synchronization, path delay could potentially be a problemfor COMPACT large cells. In large cell operation, the 8.25 symbol guard period may not be

3.2.6 Expanding COMPACT with Additional Carriers

If additional carriers are added to a COMPACT system, these carriers will have the followingcharacteristic:

They will not carry CFCCH or CSCH, but may carry CPBCCH or CPCCCH on odd timeslots(see Section 3.2.3.3 ).

The number of carriers used for CPCCCH in a cell is broadcast 6 as well as on whichadditional carriers. The time slot assignment for additional CPCCCH channels shall beignored. Only the channel number is used.

The number of CPCCCH blocks will be the same as on the primary CPBCCH carrier (see

Section 3.2.3.2 ).If the carrier is used for CPCCCH, the time slot mapping of control channels of the additionalcarrier is synchronized with that of the primary CPBCCH carrier in the same sector.

Additional carriers are not used for reselection measurements.

3.2.6.1 Additional Carriers used for traffic

If additional carriers are solely used for traffic, time slot mapping is not needed. If the carrier isadjacent to a COMPACT carrier that carries control, adjacent channel interference fromneighboring cell will occur. This can be avoided by masking relevant blocks on the carrier adjacent to the control carriers.

3.2.6.2 Additional Carriers used for control

If an additional carrier is used for CPCCCH, i.e., the time slot mapping will be synchronized to theprimary CPBCCH carrier. An additional carrier will use the same time-group concept as used bythe CPBCCH carriers (see Section 3.2.2 ). The number of block allocated for CPCCCH is thesame for all carriers used for CPCCCH in a cell. The only difference with an additional carrier is

that it may not have CPBCCH. The corresponding blocks used for CPBCCH on the primaryCPBCCH carrier will on the additional carriers either be used for traffic having a higher effectivereuse or for a copy of CPBCCH.


13/36

If 2 of 3 sectors in a cluster need additional carriers, do the following: add additional carriers F4and F5 to sectors with carrier frequencies F1 and F2; add additional carriers F4 and F6 to sectorswith carrier frequencies F2 and F3; add additional carriers F4 and F6 to sectors with carrier frequencies F1 and F3.

If 1 sector in a cluster needs additional carriers, do the following: add an additional carrier F4 tosector with carrier frequency F1; add an additional carrier F4 to sector with carrier frequency F2;add an additional carrier F6 to sector with carrier frequency F3.

NOTE: This scheme can also be used to expand the PDTCH capacity of COMPACT in addition toallowing for the support of hierarchical cell structures.

used for CPBCCH and CPCCCH, respectively. NIB_A and NIB_B number of blocks for the other time-groups will be idle as defined by the time-group concept (see Section 3.2.2 ).

In a migration area, however, NIB_A or NIB_B may be greater then N_A and N_B for some or alltime-groups. If NIB_A or NIB_B is greater than N_A and N_B for the serving time-group, theadditional number of blocks beyond N_A and N_B will be idle. For other time-groups, the number of blocks indicated by NIB_A and NIB_B will be idle for that time-group.

Example: Let us assume a network of 4/12 reuse that in general is using 1 CPBCCH (N_A = 1)and 3 CPCCCH blocks (N_B = 3) and that time-group 2 (3 sectors) in a 4/12-cluster needs oneadditional CPCCCH block (N_B = 4). Of course, the other time-groups in the same 4/12-cluster will not use this additional block when the sector of interest is using it for control (see Figure 10 ).This is not enough though, since some neighboring clusters will also have to leave this block

unused. In these neighboring clusters, NIB_B for TG2 will indicate one additional block (NIB_B =4) even though TG2 in this cluster only uses 3 CPCCCH blocks (N_B = 3). In this neighboringcluster the other time-groups will make TG2 idle as if it had 4 CPCCCH blocks.

Note that if an additional carrier is used for CPCCCH in part of a system and for traffic elsewhere,another kind of migration area is needed.

3.2.8 New Broadcast information on PBCCH

Number of idle blocks associated with CPBCCH (NIB_A) for each of the four time-groups(14). For each time-group, except the serving time-group, NIB_A indicates the number of blocks associated with CPBCCH that the BSS will make idle in downlink when creating thehigher effective reuse (see Section 3.2.2 ). The MS shall ignore these idle blocks and interpretUSF for these blocks as not received; thus implicitly the MS will make the succeeding uplinkblock idle (see Section 3.2.4 ). It is optional for the BSS to broadcast NIB_A. If NIB_A is notbroadcast then the MS shall not ignore any blocks associated with CPBCCH. The BSS thenrelies on the MS not being able to receive USF in idle downlink blocks.

(14). For each time-group, except the serving time-group, NIB_B indicates the number of blocks associated with CPCCCH that the BSS will make idle in downlink when creating thehigher effective reuse (see Section 3.2.2 ). The MS shall ignore these idle blocks and interpretUSF for these blocks as not received; thus implicitly the MS will make the succeeding uplinkblock idle (see Section 3 2 4 ) It is optional for the BSS to broadcast NIB B If NIB B is not

3.2.10 Power Control and Interference Measurements

3.2.10.1 Power Control Power control for COMPACT works in the same manner as for regular EGPRS the onlydifference being that COMPACT uses a discontinuous CPBCCH carrier and inter base stationtime synchronization which necessitates a slightly more sophisticated serving cell received signallevel measurement strategy (the same as that used for COMPACT cell reselection, see Section3.4.2).

3.2.10.2 Interference Measurements

For regular EGPRS, downlink co-channel interference measurements are made by a mobilestation on the same RF carrier frequency as its assigned PDTCH during logical IDLE frames(frame numbers 25 and 51 in a 52 multiframe structure on slots not requiring BSIC decoding) andPTCCH frames (frame numbers 12 and 38 in a 52 multiframe structure on slots not requiringcontinuous timing advance procedures) (see GSM 05.08).

For COMPACT, all PDCHs (i.e., both logical control channels and traffic channels) employ logical52 multiframes and all cells are time synchronized such that IDLE frames coincide on all RFcarrier frequencies in all cells. Therefore, for COMPACT a "new" downlink co-channelinterference measurement technique is defined because there will be no signal for a mobilestation to measure during COMPACT IDLE frames.

For COMPACT, the downlink co-channel interference signal level is measured during the PDTCHin a timeslot of a multiframe. No measurements need be taken on the CPBCCH, CPCCCH,PTCCH, CFCCH, or CSCH since the BTS of the neighboring co-channel cells either does nottransmit or transmits with constant output power.

One method for doing this is to make use of the orthogonality of the 8 PDTCH 26 symbol TrainingSequence Codes (TSCs). An example algorithm for interference estimation at the mobile stationduring the TSC of a PDTCH in a timeslot of a multiframe is presented below.

Example Algorithm:

The symbol spaced sampled complex envelope of the received signal r (t ), {r n}, can be expressedas follows:


16/36

K will be decided based on the expected maximum equivalent channel dispersion. Note that theequivalent channel corresponds to the combined channel response of the physical channel andtransmit and receive filter responses. K represents the number of symbols over which theequivalent channel dispersion is spanning. K = L1+L2 +1.

STEP 2:

The interference and noise contribution ( IN ) is calculated for the last M symbols of the TSC asfollows:

=

= M

k

k k uW r

M IN

21

Note that the accuracy of the interference estimate will improve as M increases, on other handthe channel estimate may suffer because of a reduced N . Optionally, the symbols in theimmediate vicinity on either side of the TSC may also be used in estimating interference.

STEP 3:

The above procedure may be performed in both the directions scanning TSC from left to right andright to left. By scanning in both the directions, IN can be obtained for the first M symbols, IN1,and for last M symbols, IN2 . SS CH,n is calculated as follows.

SS CH,n = (IN1+IN2)/2

An example of one way to assign TSCs for COMPACT using the aforementioned examplealgorithm is illustrated in Figure 5.

3.3 Cell Selection

3.3.1 ANSI-136 Capable EGPRS TerminalsTerminals with 30 kHz ANSI-136 support will first acquire a 30 kHz digital control channel (DCCH)according to ANSI-136 procedures. If an acceptable 200 kHz EGPRS-136 system exists, apointer to this system is available on the 30 kHz DCCH. Upon finding such a pointer, the terminalwill leave the 30 kHz system and begin an initial access to this EGPRS system. The terminal willscan the 200 kHz carriers according to information in the pointer. The use of this pointer willsignificantly reduce initial scanning time.

3.3.2 Pure EGPRS Terminals (non ANSI-136 Capable)The high level objectives are (see also B):

Ensure that GSM voice capable terminals do not automatically select a packet only network.

Enable packet only terminals to automatically select the highest prioritized PLMNindependent of its capabilities: GSM, CLASSIC (TDMA/EGPRS), or COMPACT(TDMA/EGPRS).

Provide information to the user of each PLMNs capabilities (voice, packet, or both) when

performing manual network selection.In case an emergency call is initiated when the serving cell is a packet only cell (CLASSIC or COMPACT), then the terminal should immediately start searching for any cell offeringemergency service and initiate the call when such a cell is found.

Allow roaming of handsets using data services in a manner such that the most-preferred datanetwork is searched for and, at the users discretion, employed for data traffic.

Allow roaming onto data-only networks when no voice service is available.

Allow the search for the most-preferred data network to occur only if the network operator or user has programmed the users SIM accordingly.

The three last bullets will not impact network selection times for operators and users who do notwish to roam on the most-preferred network for data services


18/36

3.3.2.3 PLMN Selection

At switch on or recovery, it is important to cover the case for any MS (e.g., even packet onlycapable MSs that last visited a COMPACT network) to easily find back to the RPLMN if it exists.Thus it is possible to store also CPBCCH carriers as RPLMN carriers, and in the CRs, anadditional note is introduced to account for that the time it takes to find a certain RPLMN isdependent on whether any CPBCCH carriers are stored or not.

Further, a stored list for HPLMN CPBCCH carriers is required for COMPACT capable MS tospeed up the selection when returning back to a HPLMN with COMPACT.

3.3.2.4 Automatic Network Selection

Some additional requirements for the automatic scan are introduced, to be able to fulfil the overallgoal of introducing minimum changes to the existing procedures.

First, as mentioned, an MS with voice capacity shall ignore all PLMNs where they find a cellbroadcasting CELL_BAR_QUALIFY_2 =1. This means that it is a PLMN where parts of thenetwork do not support circuit switched voice.

In addition, this also means that there is no need for a voice capable MS to search for anyCPBCCH carriers, since there will be no circuit switched voice service available for release 99 inCOMPACT networks.

Attached to the stored list of PLMNs, there will also be a Network Type field (Radio AccessSystem Type), that indicates whether COMPACT CPBCCH carriers or BCCH carriers (or both)are used. This will enable more flexibility to control what radio access bearers the MS scans for when looking for HPLMN and PLMNs on the PLMN selector on the SIM. The intention is for thesechanges to also be forward compatible to handle new network types in the future, e.g., UMTS.

It is only necessary to perform a search according to the search algorithm specified for thenetwork type associated with the PLMN to which a selection attempt is made, see also GSM05.08 for the search descriptions. If more than one network type is specified, (this can typicallyoccur in systems where COMPACT and Classic cells are mixed) an MS may start to scan for theNetwork Type that take the shortest time to find. This is the Classic network type, or, the NetworkType where a continuous broadcast carrier is used.

We are addressing also the steps in the PLMN selection algorithm that do not refer to any stored


19/36

the existence of a packet data network that is a more-preferred network compared to the PLMNselected for voice service. The investigation scan will include scanning for any and all COMPACTnetworks that are available.

An additional pair of data bits is proposed to be added to the SIM. One bit controls whether theinvestigation scan is performed after successful PLMN registration, and the other data bitindicates whether the investigation scan is performed during limited service states. If desired,these bits may be programmed by a user or operator so that the investigation scan is notperformed.

3.3.3 Acquire Synchronization on a Scanned EGPRS Classic Channel

The method to acquire EGPRS Classic is the same as for core EGPRS [1].

COMPACT is using a discontinuous CPBCCH carrier and a new method is needed to performinitial acquisition. The initial cell selection is enabled by the introduction of a frequency correctionand synchronization burst in the 52 multi-frame structure for the packet common control channels(see Section 3.2.3 ). A terminal will require more time for the initial scanning in COMPACT than in

EGPRS Classic. This is due to three additional challenges. First, the control carriers are nottransmitted continuously. Secondly, there are only one CFCCH and one CSCH per multi-frame.Third, the control channel is rotating over the timeslots.

The structure of the 52 multi-frame provides the following characteristics to reduce thesechallenges:

The time period between CFCCH, CSCH and the first CPBCCH block is always the same(207 bursts between CFCCH and CSCH and 7 bursts between CSCH and the first burst inthe first CPBCCH block).

The first CPBCCH block always occurs in block 0. As a minimum, block 0, 5, 8, and 11 are always used for control in the downlink.

The CSCH indicates the serving time-group, enabling the terminal to track the rotating control

3.4.2 COMPACT

Another issue that has been addressed in the development of COMPACT is that of neighbor cellmeasurements, or more general, cell reselection on 200 kHz carriers. Without a continuouscontrol channel carrier, it is evident that the neighbor cell measurement strategies will have to beslightly more sophisticated than at present. A mobile can only measure signal strength fromneighbor cells during certain blocks.

3.4.2.1 Neighbor Cell Measurement Method

A terminal in COMPACT mode knows exactly when each neighbor transmits control relatively toits serving cell. Due to propagation delay, however, signals from neighbor cells will normally

arrive later than signal from the serving cell. In other cases, the signals may arrive earlier, e.g.,when the MS is close to a micro-cell in the outer part of a large cell.

To ensure that the measurement is made on the neighbors transmitted signal, the terminal shallbase its initial RSSI measurements on a fraction of the burst. The MS must avoid a significantpart of the beginning of the burst to guarantee measurement on distant neighbors. (The maximumdistance difference from first neighbor ring is 70 km, but second ring may be even further away.)The MS must also avoid a part of the end of the burst in case the neighbor is a nearby micro-celland the MS is in the outer part of a large cell (maximum distance difference 35 km).

After decoding the BSIC in the CSCH from a specific neighbor, the MS can deduct thepropagation delay from the neighbor and may perform the RSSI measurements on larger part of the burst.

3.4.2.2 Neighbor Cell Measurement Opportunities

With time slot mapping of control channels in a rotating fashion, the MS can see all the neighbor cells in its normal measurement window. During one 52-multiframe, the MS is able to measureone time-group on all 3 frequencies once per control block. During 1 s time period (4 multi-frames), the MS is able to measure all 4 time-groups from all 3 frequencies.

Assuming a worst case scenario where the traffic is continuous and symmetric (compare circuitswitched) and that only one measurement can be made in each frame, at least 7 measurementsper second can be performed for each of the 12 neighbors.


21/36

special care needs to be taken for multi-slot modes where the MS only can make a measurementin one timeslot per frame. In such cases, one of the following actions needs to be taken:

Allocate such that the timeslot where the MS can make a measurement occurs when controlis transmitted.

Allocate fewer slots such that the MS is able to measure when control occurs.

Use traffic scheduling to provide enough measurement opportunities.

3.4.3 EGPRS Classic to COMPACT

If an EGPRS Classic cell defines COMPACT cells in its neighbor list, the EGPRS Classic cell

shall be synchronized to the COMPACT cells (see Section 3.2.1 ). This will ensure that theterminal will know when it is able to perform RSSI measurements (see Section 3.4.2.2 ). Further,the same consideration for allocating multi-slot operation needs to be taken as in COMPACT (seeSection 3.4.2.3 ).

3.4.4 COMPACT to EGPRS Classic

There are no additional requirements when an EGPRS Classic cell occurs in the neighbor list of aCOMPACT cell. The terminal can easily perform RSSI measurement, since the BCCH carrier iscontinuous. It is also possible to perform BSIC decoding as in core EGPRS utilizing the slidingfeature created by the different length multi-frames (52 in COMPACT and 51 for BCCH in EGPRSClassic).

3.4.5 New Broadcast information

The following information is needed for each neighbor in the neighbor list, both for BCCH andCPBCCH:

Indicator of continuous (EGPRS Classic) or discontinuous (COMPACT) control carrier.

If discontinuous control carrier, the time group number: 1, 2, 3, or 4.

If discontinuous control carrier, the minimum number of control blocks being used, from 4 upto 12 (all steps not needed).

4.1 Frequency Numbering

The following channel numbers have already been used:

DCS 1800 systems make use of channel numbers 512 through 885;

PCS 1900 systems make use of channel numbers 512 through 810;

P-GSM 900 and E-GSM 900 systems make use of channel numbers 1 through 124 and 0through 124 plus 975 through 1023, respectively;

GSM 450 systems make use of channel numbers 259 through 293; and

GSM 480 systems make use of channel numbers 306 through 340.

For the 850 MHz band, the system will be required to operate in the following frequency bands:

824 - 849 MHz: mobile station transmit, base station receive

869 - 894 MHz: base station transmit, mobile station receive

In order to avoid re-using channel numbers as was done with DCS 1800 systems and PCS 1900systems which could potentially impair the roaming capability of multi-band mode mobile stations,the suggested channel numbering for the 850 MHz band makes use of channel numbers thathave not yet been allocated in GSM 05.05. Table 1 illustrates the suggested channel numbering

for 850 MHz operation.The carrier frequency is designated by the absolute radio frequency channel number (ARFCN). InTable 2, we can see the relationship between ARFCN n and the frequency value of this carrier inboth the lower and upper band denoted as Fl( n) and Fu( n), respectively.

4.3 Mobile Station Conformity

Some changes are needed in GSM ETSI 11.10-1 Conformance Specification [6] because of new850 MHz frequency band. Changes are needed at least for chapters 12 (Transceiver conducted

and radiated spurious emission), 13 (Transmitter) and 14 (Receiver). Main changes are expectedto be due to new channel numbers. It is expected that parameters will be the same as in GSM900 MHz band, since the bands are so close to each other and duplex separation (45 MHz) andbandwidth (25 MHz) are the same in both bands.

Appendix A COMPACT 52 multi-frame structures

This appendix contains a number of figures that illustrate the COMPACT frame structure. Thefigures are based on matrices with 8 columns and 52 rows, where the columns represent the 8timeslots and the rows represent succeeding frames in a 52-multiframe. The allocation of eachburst in the matrix (a specific time slot in a specific frame) is given using the legend shown inTable 5.

The time slot mapping is rotating the control over the odd time-slots (see Section 3.2.2) . Therotation is occurring once a multi-frame between frame 4 and 5. The pattern of rotation over the 4odd time-slots will consequently repeat itself every 4 th multi-frame creating a 208 multi-framepattern. If the sequence number of a 52 multi-frame is denoted N, then the four different rotation

possibilities (0, 1, 2, and 3) is given as N MOD 4.Figure 5: COMPACT 52-multiframe structure

This figure illustrates the 52 multi-frame structure for all four time-groups where N MOD 4 = 0,where each time-group is allocated 1 CPBCCH and 3 CPCCCH blocks.

Figure 6: COMPACT 52-multiframe structure using 3 time groups

This figure is similar to Figure 5 , but only 3 time groups are used Time-group 4 is unused andhas no control blocks allocated to it (NIB = 0 for time-group 4). This scheme can be usedwhen using a 3/9 effective reuse for control.

Figure 7: COMPACT 52-multiframe structure for large cells

This figure is similar to Figure 5 , but the cell size is large (see Section 3.2.5 ).

Figure 8: COMPACT 208-multiframe structure, time-group 1 illustrated

This figure shows the 208-multiframe structure for time-group 1 in a system where all four time-group is allocated 1 CPBCCH and 3 CPCCCH blocks.

Figure 9: COMPACT 208-multiframe structure using 3 time-groups, time-group 1 illustrated

This figure is similar to Figure 8 , but only 3 time groups are used (compare with Figure 6 ).
