Abstract: Methods and apparatuses are described in which dynamic voltage and frequency scaling may be used to save power when processing packets in a wireless communications device. In some cases, inframe detection may allow the device to determine whether to transition from a first (e.g., lower) voltage level to a second (e.g., higher) voltage level to process one or more packets of a received frame. For some packet types the first voltage level may be maintained. In other cases, the device may determine a bandwidth to use from among multiple bandwidths supported by the device. The bandwidth may be determined based on channel conditions. A voltage level may be identified that corresponds to the determined bandwidth and a processing voltage may be scaled to the identified voltage level. The device may be configured to operate in wireless local area network (WLAN) and/or in a cellular network (e.g., LTE).

Abstract: A communication device receives at least a portion of a packet. Power is reduced to a subset of components of a communication device. The subset of components for which power is reduced is determined based, at least in part, on a length of the packet. The power is reduced for a time period based, at least in part, on the length of the packet.

Abstract: A method for reducing power consumption in a communication device. The method includes determining, by the communication device, that a packet transmitted on a communication medium is not intended for the communication device and estimating a length of the packet. If the length is greater than a first threshold but less than a second threshold, selecting a first group of components of the communication device to which to reduce power. If the length is greater than the second threshold, selecting a second group of components of the communication device to which to reduce power. The second group of components includes the first group of components. The method includes reducing power to the selected group of components.
