Abstract: Receivers, apparatuses, and methods associated with packet classification based power saving receiver are described. In one embodiment, a method includes detecting an incoming frame at a receive unit. Expected power savings are calculated based, at least in part, on a switching time and frame duration of the incoming frame. The method further includes determining to enter an ignore frame state rather than a receive frame state based, at least in part, on the expected power savings. In the receive frame state the incoming frame is received by the receive unit. In the ignore frame state the incoming frame is either not received or not decoded. The method also includes selectively controlling the receive unit to enter the ignore frame state from the receive frame state. The receive unit is returned to the receive frame state in time to perform end of frame processing on the incoming frame.

Abstract translation: 描述了与基于分组分类的省电接收机相关联的接收机，设备和方法。 在一个实施例中，一种方法包括在接收单元处检测输入帧。 至少部分地基于输入帧的切换时间和帧持续时间来计算预期的功率节省。 该方法还包括至少部分地基于预期的功率节省来确定进入忽略帧状态而不是接收帧状态。 在接收帧状态下，接收单元接收输入帧。 在忽略帧状态中，输入帧不被接收或未被解码。 该方法还包括选择性地控制接收单元从接收帧状态进入忽略帧状态。 接收单元在时间上返回到接收帧状态，以对输入帧执行帧处理结束。
