Packet classification based power saving receiver

摘要

Receivers, apparatuses, and methods associated with packet classification based power saving receiver are described. In one embodiment, an 802.11 receiver includes receive and control units. The receive unit has a higher power receive frame state and a lower power ignore frame state. The receive unit, when in the receive frame state, receives radio frequency (RF) signals associated with an incoming frame and provides decoded information concerning the incoming frame. The receive unit, when in the ignore frame state, does not receive RF signals associated with the incoming frame and/or does not decode RF signals associated with the incoming frame. The control unit controls the receive unit to enter the ignore frame state upon determining that the incoming frame is to be filtered and to return to the receive frame state in time to receive a subsequent incoming frame and perform end of frame processing consistent with the CSMA/CA protocol.

1. A receiver apparatus, comprising:
a receive unit configured with:
a receive frame state, wherein in the receive frame state, the receive unit is configured to receive an incoming frame and to provide decoded information concerning the incoming frame; andan ignore frame state, wherein in the ignore frame state, the receive unit is configured to perform (i) not receiving the incoming frame, or (ii) not decoding the incoming frame; a controller configured to selectively control the receive unit to enter the ignore frame state upon determining a desired ratio between a switching time and an amount of time expected to be required to receive a remainder of the incoming frame exceeds a threshold, and to return the receive unit to the receive frame state in time to perform end of frame processing on the incoming frame.
