Abstract
Methods and apparatuses are provided that facilitate sounding antennas in wireless communication. In an aspect, a method for wireless communication includes determining at least one resource reserved for transmitting a demodulation reference signal and transmitting a sounding reference signal over the at least one resource. In another aspect, a method of wireless communication includes signaling a parameter related to sounding multiple antenna ports, receiving signals from a device over the multiple antenna ports, and estimating a channel related to the signals at least in part by removing a precoding from the signals.
