    • Methods and apparatus to manage power consumption in wireless devices are disclosed. A disclosed example apparatus comprises performing a first received signal strength indicator (RSSI) scan to determine a beacon interval and a first beacon time for a wireless channel, calculating a second beacon time for the wireless channel based on the beacon interval and the first beacon time, and performing a second RSSI scan for the wireless channel during a time interval that includes the calculated second beacon time. In some examples, the wireless channel is a wireless channel that was previously identified as active, is a wireless channel that previously had the highest received power level, and/or is selected from a list of popular or frequently used channels. Additionally or alternatively, when a wireless channel with sufficient signal level is identified, scanning for additional channels is not performed.

    • A method provides forward compatibility hooks for DFS and TPC for WLAN, so that the same mechanisms can be employed (with only minor changes/additions) for other regulatory domains, other bands, and/or other purposes. The current IEEE 802.11 h standard defines mechanisms for dynamic frequency selection (DFS) and transmit power control (TPC) that may be used to satisfy regulatory requirements for operation in the 5 GHz band in Europe. The present method provides a format to allow other bands, and relates to the supported channels element, channel switch announcement element, and the Basic/CCA/RPI histogram request/report. The method optionally reserves more than 3-bits in the Basic report (Map subfield).
    • 一种方法提供用于WLAN的DFS和TPC的前向兼容性挂钩,因此可以对其他调节域,其他频带和/或其他目的采用相同的机制(仅进行微小的更改/添加)。 目前的IEEE 802.11 h标准定义了动态频率选择(DFS)和发射功率控制(TPC)的机制,可用于满足欧洲5 GHz频段运行的法规要求。 本方法提供了允许其他频带的格式,并且涉及所支持的信道单元,信道切换通告单元以及基本/ CCA / RPI直方图请求/报告。 该方法可选择在“基本”报告(映射子字段)中保留3位以上。
