1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving an antenna switch selection associated with a dual connectivity antenna configuration,
wherein the antenna switch selection is associated with a first radio access technology (RAT) and the dual connectivity antenna configuration permits communication via the first RAT and a second RAT;
determining, based at least in part on the antenna switch selection, a quantity of communication chains, associated with the first RAT, that are affected by a sounding reference symbol (SRS) antenna switching process of the second RAT, wherein the second RAT uses time-division duplexing (TDD) for wireless communication and the first RAT uses at least one of TDD or frequency-division duplexing (FDD) for wireless communication; and
selectively permitting, based at least in part on the quantity of communication chains affected by the SRS antenna switching process, a reconfiguration of the dual connectivity antenna configuration according to the antenna switch selection.
