Abstract
A wireless communications device may reduce power consumption by determining that a received communications sequence is not addressed to the wireless communications device, determining how long the communications sequence will last, and placing its own receive circuitry into a low power state until the communications sequence has ended.
Claims16
An apparatus, comprising a first wireless communications device adapted to:
- receive, from a second wireless communications device, at least a portion of a first communications frame that is not addressed to the first wireless communications device;
- determine a time period that will end approximately when a communications sequence containing the first communications frame and not containing any other communications frames addressed to the first wireless communications device is to end;
- place receive circuitry in the first wireless communications device into a low power state;
- and
- remove the receive circuitry from the low power state approximately at the end of the time period.

A method, comprising:
- receiving by a receiving wireless communications device at least a portion of a wireless communications sequence that is addressed to another wireless communications device and that is not addressed to the receiving wireless communications device;
- determining by the receiving wireless communications device a time period that will end approximately when the wireless communications sequence is to end;
- placing receive circuitry in the receiving wireless communications device into a low power state;
- and
- exiting the low power state of the receive circuitry in the receiving wireless communications device approximately at the end of the time period.
2 more elements
An article comprising
- a tangible computer-readable medium that provides instructions, which when executed by a computing platform, cause said computing platform to perform operations comprising:
- receiving at least an initial portion of a frame of a wireless communications sequence;
- determining that the frame is not addressed to a wireless communications device that is performing the operation of receiving;
- reading a duration value from the frame;
- starting a timer based on the duration value;
- placing receive circuitry into a low power state;
- and
- removing the receive circuitry from the low power state upon an expiration of the timer.
