Abstract: A technique for performing AGC and DC compensation in a receiver. The receiver comprises an energy estimator for generating an estimate of the level of a received signal; an RF device to apply gain to the received signal; an AGC for controlling the RF device gain based on the energy estimation; a first DC compensation loop for finely adjusting the DC component of the received signal in fast or slow tracking mode (FTM or STM); and a second DC compensation loop for coarsely adjusting the DC component of the received signal. Three modes of AGC operations: In Acquisition, iterations of FTM fine DC adjustment, short energy estimation, and RF device gain adjustment are performed during signal timing detection. In Connected, long energy estimation, RF device gain adjustment, and STM fine and coarse DC adjustments are performed during superframe preamble. In Sleep, FTM fine DC adjustment, short energy estimation, and RF device gain adjustment are performed during superframe preamble.

Abstract: Apparatus and methods are disclosed for control of an idle mode in a wireless device. In particular, the idle mode duty cycle of a preamble transmission by an access point (AP), as an example, is variably or adaptively set in response to determined conditions of the wireless neighborhood. The conditions determined include the whether or not other wireless devices are present in the vicinity of sensing wireless device, as well as the state of those devices present, such as whether they are in an idle mod or an active mode.

Abstract: Apparatus and methods for controlling sleep mode in a wireless device are disclosed. The sleep mode is controlled using low power detection of RF beacon signals of known frequencies to reduce power consumption of the wireless device during sleep modes. Detection is achieved by using passive or low power elements in a receive chain that filters received signals allowing beacon signals of particular frequencies to pass,which are accumulated with passive or low power circuit elements requiring no external power source. The accumulated energy is compared to a threshold to determine the presence of the beacon with sleep circuitry. When the beacon is detected, the full RF receiver is triggered to wake up. Use of low power elements and passive elements, affords a beneficial increase in power savings for the wireless device, which is particularly helpful in wireless access points or relay stations that have an alternative power sourcing such as battery or solar power.

Abstract translation: 公开了一种用于在无线设备中控制睡眠模式的装置和方法。 使用已知频率的RF信标信号的低功率检测来控制睡眠模式，以减少睡眠模式期间无线设备的功耗。 通过在接收链中使用无源或低功率元件来实现检测，该接收链对接收到的信号进行滤波，允许特定频率的信标信号通过，这些信号是不需要外部电源的无源或低功率电路元件。 将累积的能量与阈值进行比较以确定具有睡眠电路的信标的存在。 当检测到信标时，触发完整的RF接收机唤醒。 使用低功率元件和无源元件，为无线设备的功率节省提供了有益的增加，这在具有替代电源（例如电池或太阳能）的无线接入点或中继站中特别有用。
