Title:
ENHANCEMENT FOR SL COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2021/203411
Kind Code:
A1
Abstract:
For SL CSI-RS transmission for SL CSI measurement, it can be rated matched according to the presence derived from SCI field (e. g., 2 nd SCI) for CSI request and the configuration of CSI-RS resources. Additionally, CSI-RS resources can be mapped on the PSSCH resources transmitting TBs. Alternatively, SL CSI-RS resources can be punctured. It will be transparent to UE receiver with minor or ignorable performance degradation. For SL CSI reporting, the assumed SL CSI table (e. g., 64QAM, 256QAM or URLLC table) can be configured per resource pool/BWP and/or exchanged between UEs by PC5-RRC. Alternatively, the assumed SL CSI table can be indicated in SCI field (e. g., 2 nd SCI) from a set of (pre-) configured CSI tables. For the SL BWP with the number of RBs not the multiple of sub-channel size which is configured as N RBs per sub-channel, one or multiple resource pools can be configured for fully utilizing all resources with the minimized fragmented resources (i. e., not multiple of the sub-channel size). The multiple resource pools can be configured for a SL BWP with at most (or at least) one resource pools configured with RBs not the multiple of the sub-channel size. PSSCH transmission/reception will be restricted to the resources which are the multiple of sub-channel size.
