Patent ID: 11777686

Abstract:
Systems and methods for joint and separate beam indication in a wireless communication system. A method of operating a user equipment (UE) includes receiving configuration information for a first set of transmission configuration indicator (TCI) states for joint TCI states or downlink (DL) TCI states and for a second set of TCI states for uplink (UL) TCI states if configured to operate with separate beam indication; receiving M TCI state code points; and if M>1, receiving downlink control information (DCI) that indicates at least one TCI state code point from the M TCI state code points. The method further includes determining a TCI state to apply to at least one of DL channels and UL channels; updating one or more spatial filters based on the determined TCI state; and at least one of receiving and transmitting the DL channels and the UL channels, respectively, based on the updated spatial filters.
