5 Introduction 1 By this document, Kyocera team respectfully submits Technology Performance and 2 Evaluation Report 1 for the proposed TDD technology tilted MBTDD 625k-MC (BEST-3 WINE) (Broadband MobilE SpaTial Wireless InterNet AccEss), which is an enhanced air 4 interface based on “ATIS-PP-0700004-2005, High Capacity-Spatial Division Multiple 5 Access (HC-SDMA), (Pre Published American National Standard)”[1]. 6 This Evaluation Report 1 report presents both the link and system level Technology 7 Performance results obtained from simulations by following the methodologies specified in 8 the Evaluation Criteria Document [5] while using Suburban Macro Channel model and 9 related spatial parameters as defined in Channel Model document [4]. Both the link level and 10 system level performances are obtained at the User Terminal (UT) mobility speeds of 3kmph 11 and 120kmph. Also this report provides link budget calculation for each of the channel 12 models. 13

5.1 Purpose of This Report 14

15 This Evaluation Report 1 serves as the basis for comparing with other technology proposals. 16

5.2 Key Technologies 17

Key technologies of the MBTDD 625k-MC (BEST-WINE) system are 18 Adaptive Antenna Array Processing 19 Spatial Division Multiple Access 20 Link Adaptation with Modulation and Coding 21

5.3 System Model 22

5.3.1 Cell layout: 19BS / 3sector 23 The system layout consists of 19 cells with each cell split into 3 sectors as shown in Figure 24 5-1. Inter BS separation is 1.73 km and the cell radius is 1km. 25 Each cell is divided into 3 sectors, characterized by the antenna direction of each sector. The 26 sectors are numbered counter-clock wise as 0, 1 and 2, respectively, where the respective 27 antenna direction is 0: θ=0°, 1: θ=120°, 3: θ=240°; θ is the local polar angle of the cell. 28 Following this convention, the first sector of the center cell is indexed (0, 0), while the last 29 sector is indexed (18,2). Mobiles are uniformly dropped in each sector excluding an area of 30 radius 35 meters around the cell center. The unit of distance is meter. Each sector in each 31 base station employs antennas that has radiation pattern as shown in Figure 5-2 . 32

MBTDD 625k-MC (BEST-WINE) System employs Adaptive Antenna Array processing 8 using MMSE algorithm. Antenna array weights are calculated for the uplink transmissions 9 and the same weights are used for Downlink transmissions that follow. 10

5.5.2 MBTDD 625k-MC (BEST-WINE) Modulation classes 11 MBTDD 625k-MC (BEST-WINE) system supports 10 modulation classes, referred as 12 ModClass, which defines the modulation and coding scheme combination. There are 10 13 ModClasses as mentioned in the Table 5-4. The tiered multilevel modulation schemes 14 facilitate link adaptation. 8 different modulation schemes are incorporated, namely: BPSK, 15 QPSK, 8-PSK, 12QAM, 16QAM, 24QAM, 32QAM and 64QAM. The data rates per carrier 16 associated with these ModClasses are shown in the Table 5-4. 17 18

6.1 Link – System Interface 2

The simulations were divided into two steps, link level simulation and system level 3 simulation. The SINR versus FER characteristic were obtained by the link level simulation 4 for all the modulation classes. Based on this link level simulation results, system (network) 5 level simulations were carried out to obtain the performance of MBTDD 625k-MC (BEST-6 WINE) air interface in the defined suburban macro radio test environment. 7

In the measurement of minimum service level, the degradation due to the increase in the 6 number of load users is larger compared with the degradation due to the increase in base 7 station separation. 8 In the 120 km/h simulation [vehicular B], aggravation of frequency efficiency was seen 9 compared with 3 km/h [Pedestrian B]. 10

9 Practical System Results 11 The proposed MBTDD 625k-MC (BEST-WINE)’s base system HC-SDMA [1] has been 12 implemented and tested in some countries. The section illustrates the performance results 13 using spatial channels delivering high spectrum efficiency in Australia. 14

HC-SDMA [1] implemented spatial channel testing on Nov 7th 2003 at North Sydney (North 15 ride). Base station had 12 dipole antennas on a 25m high tower and user terminals were of 16 PCMCIA type as shown in Figure 9-1. Total 5MHz bandwidth (625kHz x 8Carrier) was used 17 for performance testing. The base station performs 8 carrier communications, including BCH, 18 and 3 spatial channels simultaneously. User terminal needs to use 625kHz bandwidths for 19 1Mbps communication. Therefore, base station delivered the following data rates to a total of 20 24 (3 × 8) users simultaneously. 21 22 User terminal data rate without BCH : Uplink 1,061 kbps 23 Downlink 346 kbps 24 User terminal data rate with BCH : Uplink 707 kbps 25 Downlink 231 kbps 26 27 So, Aggregate data rate (1,061 kbps ＋ 346 kbps) × 7 Carrier × 3 Spatial 28 + (707 kbps + 231 kbps) × 1 Carrier × 3 Spatial ≅ 32.4 Mbps. 29 30 HC-SDMA [1] system could deliver aggregate data rate ≅ 32.4 Mbps. The corresponding 31 maximum spectrum efficiency that is achieved in 5MHz band is 32.4 Mbps / 5 MHz ≅ 6.5 32 bit/sec/Hz/cell. 33 34 35

2006-JAN-06 IEEE C802.20-05/77r1


Figure 9-1 25m-high Tower, User terminal and Sydney MAP 1

The test result for 24 terminals communication achieved a total of 29.6Mbps. Figure 9-2 2 show throughput result for downlink performance. The logical maximum data rate is 3 32.4Mbps as already stated. From this result, spatial throughput efficiency is computed as 4 29.6Mbps / 32.4 Mbps ≅ 0.913 91.3%. 5 Furthermore, the test achieved spectrum efficiency is computed as 29.6 Mbps / 5 MHz ≅ 5.9 6 bit/sec/Hz/cell. 7
