Abstract: A wireless local area network (WLAN) protocol having a non-zero backoff procedure which is bounded by setting a backoff counter to a random value greater than or equal to at least one backoff slot in starting to contend for a channel. This is preferably utilized in combination with setting the Arbitration Inter-Frame Spacing (AIFS) time to an amount less than that utilized for a legacy backoff. The parameters controlling the non-zero backoff may be set by the station performing the contention, or by an associated Access Point (AP), or in response to negotiation between the station and the AP. In some cases the station can switch between enabling and disabling the non-zero backoff procedure during different periods of time.

Abstract: Systems and methods directed to returning personalized image-based search results are described. In examples, a query including an image may be received, and a personalized item embedding may be generated based on the image and user profile information associated with a user. Further, a plurality of candidate images may be obtained based on the personalized item embedding. The candidate images may then be ranked according to a predicted level of user engagement for a user, and then diversified to ensure visual diversity among the ranked images. A portion of the diversified images may then be returned in response to an image-based search.

Abstract: Protocol enhancements for IEEE 802.11 handling of Buffer Status Reports (BSRs) to provide real-time information on Quality of Service (QoS) requirements. A non-AP STA can report QoS status about portions of a buffer, which then allows the AP to schedule transmissions for those buffers toward satisfying their QoS requirements. The non-AP STA can also change parameters of the QoS characteristics element of an existing SCS to allow the AP to schedule transmission for the SCS traffic with the new parameters immediately. The non-AP STA can also report on buffers that should soon arrive to allow the AP to trigger the transmission before those buffers arrive. Additional benefits are also provided.
