Abstract: An access point may advertise (e.g., broadcast) identifying information (e.g., a neighbor report and access point capability information) on a dedicated channel in a wireless network. The identifying information may include information about neighboring access points in the wireless network. The neighboring access points may operate on the dedicated channel, a different primary operating channel, or a combination thereof. A station entering the wireless network may scan the dedicated channel to detect the identifying information from the access point to aid relatively quick discovery of the neighboring access points without scanning multiple channels.

Abstract: Methods, devices, and systems are described to enable generating and securely distributing a common network key in a wireless network. For example, instead of each station of the wireless network generating a station-specific group network key, a particular station may generate and securely transmit a common network key to be used by multiple stations in the wireless network to decrypt group messages from multiple stations in the wireless network.

Abstract: Systems and methods for more efficient mesh associations are disclosed. In some aspects, a non-member device may join a mesh network via a four way message exchange with any member device of the mesh network. The four way message exchange between the mesh member device and the non-member device provides for authentication and association between the two devices. As a result of the four way message exchange, a common group key is provided to the non-member device. The common group key is utilized by all mesh member devices to encrypt and decrypt group addressed mesh messages exchanged between any of the mesh member devices. Association identifiers for each of the two devices are also provided during the exchange. PHY/MAC capabilities may also be exchanged. In some aspects, IP address assignment for the two devices may also be accomplished during the four way message handshake.

Abstract: Systems and methods for multi-hop service discovery within a mobile device cluster are disclosed. A seeker station may be seeking or may have found a desired service available from a provider station. The seeker station may receive the service announcement from the provider station, and become a proxy station, expanding the service area of the provider station. The proxy station may selectively transmit services and advertisements for services on behalf of the provider station based on restrictions placed on selection as a proxy station. Restrictions or conditions may be placed on the proxy station limiting the number of stations that may become proxy stations, limiting traffic within the cluster. Some restrictions may require a proxy station to be a member of the cluster or a member of a group within the cluster. Selection as a proxy station and frequency of transmission of service announcements by proxy stations may also be conditioned on various specific parameters or combinations of parameters as specified by the provider station.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for coordinated scheduling of service periods (SPs). In some aspects, an access point (AP) may receive timing information indicating an SP associated with an overlapping basic service set (OBSS) and may transmit, to its associated STAs, coordinated timing information indicating the timing of the SP in relation to its timing synchronization function (TSF) timer. In some aspects, the AP may adjust the timing information to account for an offset between its TSF timer and a TSF timer associated with the OBSS. In some other aspects, the AP may synchronize its TSF timer with the TSF timer associated with the OBSS. The AP may further communicate with the STAs based on the coordinated timing information. For example, the AP may schedule communications with the STAs to be orthogonal to communications in the OBSS during the SP.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) may transmit a packet, at the beginning of a restricted TWT SP, that signals all non-member wireless stations (STAs) to defer access to the wireless medium for at least a threshold duration. Upon receiving the packet, any non-member STAs that are associated with the AP may set their network allocation vectors (NAVs) according to the duration indicated by a duration field of the received packet. In some implementations, low-latency STAs that are members of the TWT SP may not set their NAVs according to the duration field of the received packet. Instead, the low-latency STAs may access the wireless medium before the NAVs associated with the non-member STAs expire.

Abstract: This disclosure provides methods, devices and systems for reliable delivery of enhanced broadcast services (EBCS) downlink (DL) packets to wireless stations (STAs) that support EBCS (also referred to as "EBCS STAs") and maintaining interoperability with STAs that do not support EBCS. A wireless communication device may broadcast one or more EBCS DL packets carrying data associated with an EBCS service. In some aspects, the wireless communication device may subsequently transmit a trigger frame soliciting information indicating which, if any, of the EBCS DL packets were missed by EBCS STAs in the vicinity. In some other aspects, each EBCS DL packet may carry signaling indicating that the broadcast data is intended only for EBCS STAs. Still further, in some aspects, the wireless communication device may broadcast an EBCS traffic advertisement indicating a timing of the one or more EBCS DL packets.

Abstract: In some implementations, an access point (AP) establishes a restricted target wake time (TWT) session including at least one restricted TWT service period (SP) for peer-to-peer (P2P) communications. The AP admits a group of wireless stations (STAs) associated with P2P communications as members of the restricted TWT session, obtains a transmission opportunity (TXOP) on the wireless channel during the at least one restricted TWT SP, and transmits, on the wireless channel, a protection frame identifying one or more STAs of the group of STAs belonging to the restricted TWT session that are permitted to transmit or receive P2P communications on the wireless channel during the TXOP. The protection frame may also indicate to receiving devices other than the one or more identified STAs that the wireless channel is unavailable for at least a portion of the TXOP.
