1. A method for wireless communications by a user equipment (UE), comprising:
determining, while communicating in a serving cell, information regarding one or more transmission deployment mode parameters comprising a number of transmit antennas of at least one neighbor cell, without assistance associated with the one or more transmission deployment mode parameters from the serving cell, wherein the determining comprises:
inferring the number of transmit antennas used by the at least one neighbor cell by evaluating different hypotheses corresponding to different numbers of transmit antennas, and
selecting one of the different hypotheses with a higher narrowband reference signal receive power (NRSRP) than another based on the inferring the number of transmit antennas used by the at least one neighbor cell; and
performing a neighbor cell search with measurement of NRSRP based on the determined information regarding the one or more transmission deployment mode parameters.
