Abstract

Methods and apparatus for performing receive antenna diversity measurements in measurement gaps are provided. One embodiment may include communicating with a serving base station using a first set of one or more receive antennas during a normal operational period performing receive antenna diversity measurements with a second set of one or more receive antennas during a measurement gap between normal operational periods and selecting one or more receive antennas for at least one of use and/or combining based on the receive antenna diversity measurements.
