A network node in a wireless communication network generates configuration information that configures an extent to which a wireless communication device autonomously adapts a number of different receiver components that the wireless communication device uses under different conditions at the wireless communication device. In some examples, the different conditions may be associated with correlation of propagation channels received at the wireless communication device. The network node transmits the configuration information to the device. Correspondingly, the device autonomously adapts the number of different receiver components that the wireless communication device uses in accordance with the configuration information.

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.

The second communication device transmits and indication of the selected transmit parameter to the first communication device.
