Original Abstract Submitted
Beam management may be coordinated by a centralized coordinating entity, e.g., by a gNB, that configures and schedules Channel State Information Reference Signal, CSI-RS, transmissions for beam measurement and reporting. This centralized coordinating entity may not be available for Wireless Transmit-Receive Units, WTRUs, in a SideLink, SL, mode of operation, where resource allocation is performed by WTRUs in a distributed manner. WTRU procedures for establishing and updating an SL TCI state association are disclosed, including determining a spatial domain filter to use for an SL transmission. In these WTRU procedures, a WTRU may perform CSI-RS transmissions in an SL slot, e.g., multiplexed with a PSCCH/PSSCH transmission. The WTRU may receive, in reply, CSI reporting information comprising a spatial domain filter. For further SL TB transmissions for the SL, the WTRU may use the spatial domain filter.
