Assignee: APPLE INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. An apparatus, comprising:
a memory; and
a processing element in communication with the memory, wherein the processing element is configured to:
in response to determining that a base station 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;
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.
