    Abstract: Aspects of the present disclosure provide techniques for high efficiency (HE) basic service set (BSS) operations. In an implementation, a wireless station (STA) can identify a set including one or more modulation coding scheme (MCS) and number of spatial streams (NSS) tuples for HE communications in wireless local area networks (WLANs). The STA can determine whether the set is supported by a BSS and also determine that the STA is to attempt to join the BSS in response to a determination that the set is supported by the BSS. In another implementation, the STA can set a channel width capability for high throughout (HT) communications and very high throughput (VHT) communications in WLANs to be the same as a channel width capability for HE communications in WLANs, and can transmit information that indicates that the STA has the same channel width capability for HT, VHT, and HE communications in WLANs.

    Abstract: Methods and apparatus for determining backoff values when transitioning between single-user (SU) and multi-user (MU) modes are provided. A station (STA) transitions from a Single-User (SU) mode, in which a first set of parameters is used to attempt to access a medium, to a Multi-User (MU) mode, in which a second set of parameters is used to attempt to access the medium. The STA determines, upon transitioning back from the MU mode to the SU mode, one or more values to use for setting corresponding one or more of a set of backoff counters. The STA attempts, after setting the one or more backoff counters, to access the medium for one or more SU transmissions based on the set of backoff counters.

    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.
