Abstract: A wireless device may utilize enhanced OBSS identification techniques to determine whether an interfering transmission is associated with an OBSS. In an example, a wireless device may receive a WLAN packet that includes a preamble and a data region. The wireless device may analyze the preamble to determine whether the WLAN packet is an OBSS packet. If the wireless device determines there is insufficient information in the preamble to identify the WLAN packet as an OBSS packet, the wireless device may decode a portion of the data region (e.g., a MAC header) to determine if the WLAN packet is an OBSS packet. Prior to declaring a successful decoding of the MAC header, the wireless device may confirm the MAC header has been received reliably. Additionally or alternatively, BSS identifiers may be included in the data region and used to determine if the WLAN packet is associated with an OBSS.

Abstract: A method of enabling data to be relayed between an access point (AP) and a target station (STA). The AP identifies the target STA based at least in part on a medium usage efficiency of the target STA. The AP further sends a relay selection trigger to the target STA to cause the target STA to broadcast a relay selection request to a set of candidate STAs. The relay selection request includes a set of metrics pertaining to a direct link between the AP and the target STA. The AP then receives one or more relay selection responses from one or more candidate STAs in the set of candidate STAs based at least in part on the set of metrics and selects a relay STA from the set of candidate STAs based at least in part on the one or more relay selection responses.

Abstract: A method for configuring channel access parameters in a wireless communication system includes selecting an element identification (ID) from a plurality of element IDs. Each of the plurality of element IDs identifies an enhanced distributed channel access (EDCA) parameter set element comprising at least one channel access parameter for at least one subset of wireless devices in a group of wireless devices. The selected element ID is identifiable by wireless devices of the group of wireless devices and not identifiable by other wireless devices. The method further includes generating the EDCA parameter set element for setting the at least one channel access parameter for each wireless device in the at least one subset. The EDCA parameter set element includes the selected element ID. The method further includes transmitting the EDCA parameter set element to at least one wireless device in the at least one subset of wireless devices.
