METHOD AND APPARATUS FOR JOINT AND SEPARATE BEAM INDICATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18476265 titled 'METHOD AND APPARATUS FOR JOINT AND SEPARATE BEAM INDICATION
Simplified Explanation
The patent application describes systems and methods for joint and separate beam indication in a wireless communication system. It involves a method of operating a user equipment (UE) that 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. The method also includes 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.

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.
