Abstract: Aspects of the disclosure relate to minimizing the block error rate (BLER) experienced by a user equipment (UE) upon a downlink beam switch at the base station. The UE may measure the reference signal received power (RSRP) of each of a plurality of downlink beams during a beam sweep and modify an automatic gain control (AGC) state of the UE based on the difference in RSRP between a current downlink beam and an expected downlink beam expected to be selected by the base station for subsequent unicast downlink transmissions to the UE. In some examples, the expected downlink beam may have a highest RSRP among all of the measured RSRPs of the different downlink beams Other aspects, features, and embodiments are also claimed and described.

Abstract: Wireless communications systems and methods related to hybrid in-band same-frequency full-duplex (SFFD) and frequency-offset-frequency full-duplex (FD) wireless communication are provided. A user equipment (UE) transmits first data to a base station (BS) over a first frequency band while receiving second data from the BS the first frequency band responsive to a first pathloss between the UE and the BS satisfying a threshold for an SFFD operation. The UE transmits third data to the BS over a second frequency band while receiving fourth data from the BS over a third frequency band that is distinct from the second frequency band according to an offset-frequency FD operation responsive to a second pathloss between the UE and the BS failing to satisfying the threshold.
