Abstract
Methods and apparatuses relate to sounding reference signal (SRS) transmit antenna selection in wireless communication systems. For example, a user equipment (UE) may select, from a set of antennas, a subset of antennas for SRS transmission based on at least one antenna selection parameter. The UE may further transmit, on an uplink communication channel, the SRS using the subset of antennas to a network entity. In some aspects, the at least one antenna selection parameter may include a reference signal receive power (RSRP) value, a signal-to-noise ratio (SNR) value, a spectrum efficiency value, and/or an SNR value and a channel correlation value.
