1. 1X-Advanced Framework Decisions Ed Tiedemann 3GPP2 TSG-C Working Group 3 Chair October 1, 2008

2. 1 Outline Company proposals Framework decisions Possible component decisions

3. 2 Qualcomm Proposal - 1 Frame Early Termination –Applicable to fundamental channel and supplemental channels –RL ACK using additional Walsh codes (for F-FCH, F-SCH1, F-SCH2) –FL ACK TDM’d with PCB (R-FCH) OR using Forward Common ACK Channel (R-SCH1, R-SCH2) –Larger CRCs for Eighth, Quarter, and Full rate frames Re-use of existing puncture patterns for 1/8 and 1/4 rate frames; New puncture pattern for ½ rate frame Slower Power Control –400Hz (when RL Smart Blanking disabled) OR 200Hz (when RL Smart Blanking enabled) –Larger PC step sizes when transmitting null-rate frames {0.25, 0.5, 1.0} dB for non-zero rate frames {0.25, 0.5, 1.0, 1.5, 2.0} dB for zero rate frames

4. 3 Qualcomm Proposal - 2 Smart Blanking –Guaranteed transmit frames every N frames N = 1, 2, 4, or 8; based on frame-offset Forward Link code extension via use of QOF functions –QOF defined in existing 1x specifications –Applicable to legacy terminals Supplemental Channels –Convolutionally encoded: 9.6kbps –Turbo coded:19.2kbps, 38.4kbps, 76.8kbps, 153.6kbps, or 307.2kbps

5. 4 Alcatel-Lucent Proposal Forward Link code space expansion for a sector via use of additional PN sequences

6. 5 ZTE Proposal Alternate power control timing for slower closed-loop power control Separate channel for RL power control bits

7. 6 LGE Proposal Frame Early Termination enhancements –Non-uniform Traffic-to-Pilot power ratio for frame –Enhanced outer-loop operation for early termination –Emergency Power Boost using negative NACK New puncture patterns for frames using larger CRCs ACK repetition Smart Blanking and Slower Power Control enhancements –Dynamic PC step size Complexity reduction –Rate Indicator channel Code Combining Soft Handoff with convolutional codes

8. 7 Proposed Framework Same Basic Channel Structure as 1x –Fundamental and Supplemental Channel Frame Early Termination Slower Power Control Smart Blanking Fundamental Channel Coding –Convolutional coding for all Supplemental Channel Coding –Convolutional encoded: 9.6kbps –Turbo coded:19.2kbps, 38.4kbps, 76.8kbps, 153.6kbps, or 307.2kbps

9. 8 Component Decisions Forward Link code space expansion –QOF (No changes to specification) –Use of additional PN sequences Code Combining Soft Handoff with convolutional codes Closed-Loop PC timing structure –Separate channel –Timing Rate Indicator Channel New puncture patterns for frames using larger CRCs Non-uniform Traffic-to-Pilot power ratio for frame Enhanced outer-loop operation for early termination Emergency Power Boost using negative NACK Static and Dynamic PC step sizes ACK Repetition
