1. A method of wireless communication performed by a user equipment (UE), comprising:
identifying one or more symbols, associated with downlink communication of a first radio access technology (RAT), that are impacted by antenna switching used to transmit an uplink reference signal of a second RAT; and
performing a mitigation action to mitigate downlink performance degradation associated with the first RAT based at least in part on identifying the one or more symbols,
wherein performing the mitigation action to mitigate downlink performance degradation comprises at least one of:
modifying a first channel estimate that is based at least in part on the one or more symbols, or
generating a second channel estimate using at least one of prediction, interpolation, or extrapolation and without using samples from the one or more symbols.
