Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with improving antenna selection for a UE as part of an access procedure. In an example, a UE with two or more antennas is equipped to obtain receive chain measurements for the two or more antennas associated with the UE when an access procedure is initiated, select an antenna, of the two or more antennas, for transmission based on receive chain measurements for use during at least a portion of the access procedure, and perform the access procedure using the selected antenna. In another example, the UE is equipped to determine that an Access procedure is to be initiated, select an antenna from the two or more antennas based on a selection algorithm, and perform the Access procedure based using the selected antenna. Other aspects, embodiments, and features are also claimed and described.
