Claim of US Patent No. 10,973,044

1. A method of wireless communication at a user equipment (UE), comprising:determining, for a component carrier (CC), an active transmission configuration indicator (TCI) state of at least one of a control resource set (CORESET) of a physical downlink control channel (PDCCH) when the CORESET is configured on the CC or a physical downlink shared channel (PDSCH);
determining, based on the determined active TCI state, a default beam on the CC for transmitting at least one of a physical uplink control channel (PUCCH) or sounding reference signals (SRS), wherein when the CORESET is configured on the CC, the default beam for at least one of the PUCCH or the SRS is determined based on the determined active TCI state of the CORESET of the PDCCH, wherein when the CORESET is not configured on the CC, the default beam for at least one of the PUCCH or the SRS is determined based on the determined active TCI state of the PDSCH; and
transmitting at least one of the PUCCH or the SRS through the determined default beam on the CC.
