1. A method of wireless communication, comprising:
determining, by a user equipment (UE), whether any receive beam direction associated with one or more control resource sets (CORESETs) in a second time period is usable for receiving a reference signal during a first time period using an uplink transmit beam direction for uplink transmissions during the first time period, wherein the second time period is before the first time period;
determining, by the UE in response to a determination that no receive beam direction associated with the one or more CORESETs in the second period is usable, a quasi-co-location (QCL) configuration for receiving the reference signal during the first time period based on the uplink transmit beam direction to be used for the uplink transmission during the first time period; and
receiving, by the UE from a base station (BS), the reference signal using a first receive beam direction based on the determined QCL configuration while transmitting a first communication signal using the uplink transmit beam direction in a common frequency band during the first time period.
