3 Key Features Hybrid (Scheduled + Rate Controlled) Mode of operation achieving peak data rate of 1.5 Mb/s. –Triggering by channel assignment messages and handoff messages Fast scheduling with shorter variable duration frames: –2.5, 5 and 10ms frames. Base station supervised rate control –2.5, 5, 10 and 20ms frames. Physical Layer H-ARQ Adaptive Modulation and Coding (AMC) Further Optimizations Under Investigation : –RoT-unconstrained mode –1.25 frames –Slot-orthogonal transmissions

4 Scheduled Mode Applies to all simplex or softer-HO-only mobiles Schedules mobile transmission based on RoT, mobile pilot power, and Ecp/Nt Staggered CDM (greedy filling) to maximize noise rise utilization –More than one scheduled user can be transmitting simultaneously. Uses F-USCH for schedule grant and ACK/NACK –MACID is assigned in ECAM or UHDM messages and used to identify the intended recipient of the schedule grant A 2 IR is supported

5 Rate Control Mode Apply to all SHO or soft-softer-HO mobiles Base station supervised rate control by F-UCACH Individual ACK/NACK through F-UCACH Mobile receives F-UCACH sub-channel assignment through UHDM A 2 IR is supported

6 Autonomous Transmission Autonomous Transmission on Enhanced R-DCCH –Adds 19.2kbps/384-bit rate on R-DCCH –Serves delay sensitive signaling or traffic (e.g. TCP_ACK) Rate_Limit (encoder packet size and duration) on Autonomous Transmission can be negotiated through higher layer signaling No HARQ

7 Transition between Modes All mobiles can transmit up to Rate_Limit that is set by L3 signal on enhanced R-DCCH for delay sensitive signaling or traffic (e.g. TCP_ACK)

8 Scheduled Mode Data Rates

9 Scheduled Mode MCS

10 Rate Control Mode Data Rates

11 Rate Control Mode MCS

12 Reverse Packet Data Control Channel (R-PDCCH) Functions –Reports Transmit power on R-PICH –Indicates buffer status (amount of future data to send) –Indicates R-SCH format and supports H-ARQ R-PDCCH is of the same duration as the accompanying R-SCH and is sent concurrently R-PDCCH is CRC protected –Needs to be blind decoded (for different durations)

13 R-PDCCH fields

14 Forward Uplink Control and Acknowledgement Channel (F-UCACH) Used in the rate control mode only –Communicate acknowledgements to mobile –Rate control commands to the mobile –Acknowledgement and Rate control functions are I/Q multiplexed on the same sub-channel Structure –F-CPCCH structure with longer framing –Sub-channel assignment through handoff messages

15 Forward Uplink Scheduling Channel (F-USCH) Communicate schedule grant and HARQ Feedback to mobiles in Scheduled mode: –Supports up to 256 MAC IDs –HARQ Feedback information consists of R-ACID and R-ACK. Structure (coding etc.) similar to F-PDCCH
