Abstract

Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for a user equipment (UE) to receive a message including transmission configuration indicator (TCI) states information associated with beam information for uplink or downlink resources. The UE may identify multiple channels or reference signals, or both, to which a TCI state is to be applied based on associated indications included with the TCI state information. In some examples, the TCI state information may also include indications of source reference signals for quasi co-location (QCL) assumptions for the indicated channels or reference signals. Based on applying the TCI state, the UE may determine beam information for uplink or downlink resources and may communicate with the base station accordingly.
