Classification: CPC H | IPC H

Claim 28:
29. An apparatus for wireless communication at a base station, comprising:
one or more memories; and
one or more processors coupled to the one or more memories, wherein the one or more processors are configured to:
serve as a secondary cell (SCell) for full duplex communication with a user equipment (UE) configured with at least one active downlink and uplink beam pair; and
receive, from the UE, a beam failure recovery request (BFRQ) for the SCell using an uplink resource of the SCell or a primary cell (PCell) based on a layer 1 signal to interference and noise ratio (L1-SINR) measurement for the at least one active downlink and uplink beam pair
wherein the beam failure recovery request (BFRQ) indicates a beam failure for the at least one active downlink and uplink beam pair
wherein the uplink resource is of the SCell if the L1-SINR measurement for the at least one active downlink and uplink beam pair is above a quality threshold,
wherein the BFRQ is in at least one of: uplink control information (UCI) of the SCell, or a physical uplink shared channel (PUSCH) through a medium access control-control element (MAC-CE) of the SCell; and

receive, from the UE, a scheduling request via a different cell for the uplink resource to send the BFRQ for the SCell after one or more retransmissions of the BFRQ to the base station via the UCI or the PUSCH through the MAC-CE of the SCell.
