• If spatial relationship information for a default transmission beam has not been configured, the UE determines the default beam for transmissions based on the configured pathloss RS.
• If the pathloss RS has not been configured in the CC, the UE checks if CORESETs/TCI states for a PDSCH (physical downlink shared channel) in the CC have been configured.
• The UE determines the default beam for transmissions based on a default transmission beam in another CC, a CC index, a PRACH (physical random access channel) procedure, a PUSCH (physical uplink shared channel) transmission, an SRS (sounding reference signal) transmission, and/or a PUCCH (physical uplink control channel) transmission.

Abstract
