Classification: CPC H | IPC H

Claim 15:
16. A non-transitory computer readable memory medium storing program instructions executable by processing circuitry to cause a user equipment device (UE) to:
in response to determining that a base station serving the UE has not configured spatial relationship information for a default beam for transmissions in a component carrier (CC), determine whether a pathloss reference signal (RS) has been configured in the CC; and
in response to determining that the pathloss RS has been configured in the CC, determine the default beam for transmissions based, at least in part, on the pathloss RS;
in response to determining that the pathloss RS has not been configured in the CC, determine whether any control resource sets (CORESETs) and/or transmission configuration indication (TCI) states for a physical downlink shared channel (PDSCH) in the CC have been configured; and
in response to determining that no CORESESTs and/or TCI states have been configured in the CC, determine the default beam for transmissions based, at least in part, on a physical random-access channel (PRACH) procedure.
