    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 translation: 描述了在无线通信设备中处理分组时可以使用动态电压和频率缩放来节省功率的方法和装置。 在一些情况下，帧内检测可以允许设备确定是否从第一（例如较低）电压电平转换到第二（例如较高）电压电平以处理接收帧的一个或多个分组。 对于一些分组类型，可以维持第一电压电平。 在其他情况下，设备可以从设备支持的多个带宽中确定要使用的带宽。 可以基于信道条件来确定带宽。 可以识别对应于所确定的带宽的电压电平，并且可以将处理电压缩放到所识别的电压电平。 该设备可以被配置为在无线局域网（WLAN）和/或蜂窝网络（例如，LTE）中操作。
