B.2.16 Retransmission-less CG for UL pose transmission p. 116
This clause captures evaluation results for retransmission-less CG for UL pose transmission:
- Qualcomm evaluated disabling the retransmission for CG for UL pose information so that UE does not monitor related UL retransmission scheduling DCI. Conservative MCS is configured for successful transmission of the UL pose by the first transmission.

Based on the evaluation results in Table B.2.16-1, the following observations can be made:
-
For FR1, DL + UL joint evaluation, DU, VR 30Mbps traffic at 60fps with 10ms PDB, it is observed from Qualcomm that:
-
retransmission-less CG for UL pose provides:
- power saving gain of 20.0% for all UEs
- capacity gain of -2.1%
-
performance reference CG with UL retransmission provides:
- power saving gain of 1.8%
- capacity gain of -2.0%
-
retransmission-less CG for UL pose provides:
