Adaptive control of RF low power modes in a multi-rate wireless system using device mode
First Claim
1. A method of adaptive power control for a wireless communication device, comprising:
- receiving a first portion of a beacon in a first power mode of the device;
determining whether to receive or ignore a second portion of the beacon based at least in part on a traffic indication bit in the received first portion of the beacon, wherein the first portion of the beacon and the second portion of the beacon are in a same continuous beacon frame transmission;
determining that the traffic indication bit is set; and
transitioning to a second power mode based at least in part on the determination that the traffic indication bit is set, wherein the second power mode is a higher receiving power mode than the first power mode and the transitioning is initiated upon determining that the traffic indication bit is set; and
ignoring a remainder of the beacon after the traffic indication bit.

Abstract
Methods, systems, and devices are described for power conservation in a wireless communications system. In embodiments, power conservation may be achieved by adaptively controlling power modes of a wireless communication device, and implementing lower power modes with various modes of the device. According to one aspect, the mode of the device may be a beacon monitoring mode or a delivery traffic indication message (DTIM) mode. In such a mode, the device may receive a portion of a beacon in a first power mode. The device may transition to a second, different (e.g., higher) power mode using information contained in the received portion of the beacon as guidance.

16. A wireless communication device, comprising:
-
a receiver configured to receive a first portion of a beacon in a first power mode of the device and determine whether to receive or ignore a second portion of the beacon based at least in part on a traffic indication bit in the first portion of the beacon, wherein the first portion of the beacon and the second portion of the beacon are in a same continuous beacon frame transmission; a beacon information element (IE) determiner configured to determine that the traffic indication bit is set; and a power controller configured to transition to a second power mode based at least in part on the determination that the traffic indication bit is set, wherein the second power mode is a higher power mode than the first power mode and the transitioning is initiated upon determining that the traffic indication bit is set; wherein the receiver is further configured to ignore a remainder of the beacon after the traffic indication bit. - View Dependent Claims (17, 18, 19)
