1. A method of wireless communication, comprising:
receiving a sounding reference signal (SRS) configuration from a network;
configuring at least four antennas of a scheduled entity based on the SRS configuration, wherein the SRS configuration configures at least one of the at least four antennas to simultaneously support SRS antenna switching and an uplink (UL) multiple-input multiple-output (MIMO) communication, and wherein the SRS configuration configures the scheduled entity to simultaneously support 1T4R SRS antenna switching and 1T2R antenna selection of the UL MIMO communication;
performing the SRS antenna switching simultaneously with the UL MIMO communication on the at least one of the at least four antennas; and
transmitting an SRS communication according to the SRS configuration.
