Abstract: This disclosure provides systems, methods and apparatuses for selectively acquiring communication frames from a transmitting device capable of formatting the communication frames in accordance with a plurality of PHY formats. In some implementations, a STA may filter or discard duplicate frames received from an AP based, at least in part, on a preference of the STA for one of the plurality of PHY formats. The filtering may be performed at the PHY, without forwarding received communication frames to the media access control layer (MAC) for further processing. In some other implementations, an AP may refrain from sending duplicate frames to a STA based, at least in part, on a preferred frame format of the STA. Still further, in some implementations, the STA may dynamically adjust or update its preferred frame format based on changes in the distance, or channel conditions, between the STA and the AP.
