ABSTRACT:
A wireless communications device (100) includes a primary radio frequency branch (134) and a diversity branch (136), which is enabled and disabled to balance performance and power consumption. Diversity mode operation of the device is controlled, for example, based on one or more of an estimated channel quality indicator, data reception, data rate, state or mode of the station, estimated signal to noise ratio of a pilot signal, battery power level, distance from a serving cell, among other factors.
