Maintenance on AI/ML for NR air interface
From LG Electronics
Summary
LG Electronics submits two proposals for maintenance on AI/ML for NR air interface, specifically addressing beam management specifications. The document proposes zero-padding for short RS-PAI reports on PUCCH to ensure support for 1 or 2 bit reports and clarifies CPU occupation timelines for UE-side data collection in TS 38.214.
Position
LG Electronics prefers applying zero-padding to UCI bit sequences for RS-PAI reports on PUCCH when the length is 1 or 2 bits, arguing that restricting monitoring occasions to ensure 3 or 4 bits causes unnecessary resource overhead and constrains gNB configuration flexibility. They propose adding a separate paragraph in TS 38.214 for the CPU occupation timeline of CSI reports with reportQuantity set to 'none-bm-r19' to correctly capture existing agreements and maintain consistency with the separate paragraph for 'none-csi-r19'. This clarification aims to resolve ambiguous UE behavior regarding CPU occupation for UE-side data collection for beam management.
Key proposals
- Proposal #1 (Sec: Specification support for beam management): Endorse TP for TS 38.212 to apply zero-padding until UCI bit sequence length equals 3 for 1 or 2 bit RS-PAI reports on PUCCH.
- Proposal #2 (Sec: CPU occupation time for UE-side data collection): Endorse TP for TS 38.214 to add a separate paragraph describing CPU occupation timeline for CSI report with reportQuantity set to 'none-bm-r19'.
