vs RAN1#124
TCL appears for the first time in the consolidated positions at RAN1_124bis with three proposals. For TRS, proposes studying flexible time-domain behavior with trigger mechanisms and periodic adaptation, presenting a technical case that 5G NR TRS periodic configuration lacks flexibility for energy saving. For joint DL/UL CSI acquisition in TDD, identifies non-reciprocal insertion loss at the UE RF link as a critical factor breaking channel reciprocity and proposes studying SRS insertion loss imbalance impact. Additionally proposes studying Rx imbalance among different Rx antennas for joint DL and UL CSI acquisition.

Position extracted by AI
TCL argues that 5G NR TRS periodic configuration lacks sufficient flexibility for energy saving, and proposes studying flexible time-domain behavior including trigger mechanisms and periodic adaptation. They identify non-reciprocal insertion loss at the UE RF link as a critical factor breaking TDD channel reciprocity, and propose studying the performance impact of SRS insertion loss imbalance on reciprocity. They additionally propose studying Rx imbalance among different Rx antennas for joint DL and UL CSI acquisition.
Summary
This TCL contribution proposes two study areas for 6G MIMO operation: enhancing Tracking Reference Signal (TRS) time-domain flexibility beyond 5G NR's on-demand principle, and investigating the impact of SRS insertion loss imbalance and UE Rx imbalance on channel reciprocity in TDD systems for joint DL/UL CSI acquisition.
