Direct Signaling Connection Re-establishment (DSCR)scheduling priority indicator (SPI)*transmission serial number, connection frame number**retransmission sequence number *the first requires that each mobiledevice periodically informs the Node B of its databuffer status and transmit power headroom.ThisScheduling Information (SI) as it is known, indicatesthe priority and amount of data in the buffer waitingto be transmitted and transmit power headroom.However the SI contains large amounts of information,which not only requires encoding but also presentsan additional signaling overhead, both of whichreduce network efficiency.As a result, a second preferred method allows themobile device to simply send a single bit of information,the Happy Bit, to the Node B indicating whether ornot it has been allocated sufficient resources for it totransmit its data. The Happy Bit is transmitted witheach TTI allowing the Node B to rapidly optimize itsallocation of uplink resources.*Redundancy version (RV = 0 for HARQ CC) or dynamic (depends on RSN for HARQ IR)*Its because you can then send the SRB on the HSUPA channel, freeing up the codes that can be allocated in such a way that you can get 2SF2 + 2SF4, allowing you up to 5.8Mbps.*TOAWS Time of Arrival Window Endpoint, startpoint****With F-DPCH we can multiplex 10 users on one SF256 thus the impact on the OVSF tree is greatly reduced.set of radio resources dynamically shared among multiple users, primarily in the time domain ...
