Abstract: Embodiments enable privacy protection for increasing service anonymity. A method comprises receiving a service discovery frame from a wireless device operating synchronously in a neighbor awareness network cluster, including scrambled values associated with service names, each of the scrambled values being a hash of an argument comprising the service name and a component value selected based on a current synchronous time shared with the wireless device. The received scrambled values are compared with scrambled values associated with maintained service names, each being a hash of an argument comprising a valid service name of a known service and a component value selected based on the current synchronous time. If any of the received scrambled values satisfies the comparison with a scrambled value associated with the service name, then the received scrambled value is determined to be associated with the known service.

Abstract: An interface circuit in an electronic device may receive, from an access point associated with the electronic device, a frame with management information that enables the electronic device to use a spatial-reuse technique, where the electronic device, through the spatial-reuse technique, adjusts a transmit power and a channel-availability sensing threshold. Moreover, the management information may specify parameters for the spatial-reuse technique. Then, the electronic device may transmit, using the spatial-reuse technique, one or more frames to the access point based on the parameters. Furthermore, the electronic device may transmit, to the access point, feedback information that indicates communication performance during the communication between the electronic device and the access point. For example, the feedback information may include a retry rate and, more generally, communication-performance information. This feedback information may be used by the access point to modify the parameters.

Abstract: Determining wireless local area network (WLAN) channel medium usage information by WLAN access points (APs) and WLAN stations (STAs) is disclosed. A new medium access control (MAC) duration field in a request to send (RTS) message provides a duration value to be conveyed in a subsequent clear to send (CTS) message. A channel or bandwidth can then be quickly used if an addressed STA does not respond to the RTS message. Also, a STA recognizes an unexpected silence and accesses the medium when a trigger frame is followed by a CTS timeout interval. In a third embodiment, an AP requests that STAs monitor particular channels to obtain network allocation vector (NAV) information. The STAs then respond (or informatively, do not respond) to RTS messages; thus, allowing the AP and other listening devices to determine channel medium information. The AP can then schedule data exchanges based on the determined information.

Abstract: A wireless local area network (WLAN) station (STA) reports, with a medium access control (MAC) frame, a buffer status of an urgent traffic identifier (TID) to a second STA. In some embodiments, the second STA is also an access point (AP). The delay in reporting is reduced by providing a buffer status report for the urgent TID in a data frame being transmitted to carry data for a current TID. The buffer status report, in some embodiments, provides the value of the urgent TID. In some embodiments, the buffer status report provides an indication of the amount of data in a buffer corresponding to the urgent TID. In some embodiments, the buffer status report is based on an aggregated measure of more than one buffer with data awaiting transmission. The transmission of the MAC frame, in some embodiments, is unsolicited.
