TRANSMISSION CONFIGURATION INDICATION (TCI) LIST UPDATE AND TCI SWITCH FOR CHANNEL STATE INFORMATION (CSI) REPORTING

摘要

A user equipment terminal (UE) operates in a wireless network. The UE receives a channel state information reference signal (CSI-RS) from a base station according to a transmission configuration indication (TCI) state in a CSI-RS configuration. The UE reports channel state information (CSI) to the base station. The UE receives, from the base station, indications to update a TCI state list and to switch the TCI state in the CSI-RS configuration for CSI reporting. The TCI state list update begins before the TCI state switch is completed. The TCI state refers to the TCI state list for spatial information for reception of the CSI-RS. The UE reports an out-of-bound indication to the base station for the CSI reporting in a time period when only one of the TCI state switch and the TCI state list update is completed.
