Claim:
1. A method for wireless communications, comprising: communicating with a serving base station on a serving cell carrier frequency using a first set of one or more receive antennas during a normal operational period; performing receive antenna diversity measurements on the serving cell carrier frequency with a second set of one or more receive antennas during measurement gaps between normal operational periods, wherein the second set of one more receive antennas does not include receive antennas in the first set of one or more receive antennas, and wherein performing receive antenna diversity measurements comprises switching between taking measurements for the serving cell carrier frequency from the second set of antennas in one measurement gap and taking measurements for at least one of other carriers or other radio access technologies in a different measurement gap; and selecting one or more receive antennas for use, combining, or a combination thereof, based on the receive antenna diversity measurements.
