Abstract
A wireless device comprises a primary antenna, a primary transceiver, one or more secondary antennas and one or more receive diversity chains. The receive diversity chains, in some embodiments, include transceiver capability. The wireless device measures and collects various statistics. Based on the statistics, the wireless device enables or disables one or more of the receive diversity chains with respect to a cellular radio access technology (RAT). A disabled receive diversity chain, in some instances is then powered down. During an interval when a receive diversity chain is disabled, the control logic periodically or on an event-driven basis enables a given receive diversity chain to probe channel quality indicator (CQI) and channel rank values. In some embodiments, a time interval for collecting a portion of the statistics, is adapted or backed off in anticipation of use of the receive diversity chain, based on traffic circumstances.
