SPECULATIVE POWER SAVE
First Claim
1. A method, comprising:
- receiving a beginning portion of a signal;
processing a header in the beginning portion of the signal;
determining whether a bit in the header is set indicating there are no delivery traffic indications for buffered frames contained within the frame;
halting receiving and processing of the entire frame responsive to determining the bit is set; and
switching to a power save state responsive to determining the bit is set.

Abstract
In an example embodiment, a method for speculative power saving. The beginning portion of a header (e.g. a physical layer convergence protocol “PLCP” header of a beacon) is processed to determine whether a predefined bit is set that indicates whether the frame contains any delivery traffic indication for buffered multicast and/or unicast frames. If the bit is set, indicating the frame contains no delivery traffic indication of buffered frames, receiving and processing of the frame stops (e.g. the remainder of the PPDU is not processed) and the receiver switches to a power save state. In an example embodiment, if a predefined NULL beacon frame is detected, receiving and processing of the frame (and PPDU) stops and the receiver switches to a power save state.
