Patent ID: 8750187

Claim:
A wireless communications apparatus, comprising: a receiver module comprising a first receive chain configured to receive wireless communications on first wireless communications channel and a second receive chain configured to receive wireless communications on a second wireless communications channel; and a control module, communicatively coupled with the first receive chain and second receive chain, and configured to: enable the first and second receive chains when wireless communications are received at the first receive chain; monitor an elapsed idle time during which wireless communications on the first and second receive chains of the wireless communications apparatus are idle; and disable the second receive chain when the elapsed idle time exceeds a predetermined threshold, wherein the predetermined threshold is adaptive based at least in part on historical usage data, such that the predetermined threshold is increased based at least in part on a determination that the historical usage data indicates an increased likelihood of receiving wireless communications during a first time period, and such that the predetermined threshold is decreased based at least in part on a determination that the historical usage data indicates a decreased likelihood of receiving wireless communications during a second time period.
