Abstract: Methods, systems, and devices for wireless communication are described. Stations within a neighborhood awareness network (NAN) may determine when to transmit synchronization beacons during a wake-up time based on some priority (e.g., stations with more recent clock updates or earlier time stamps, stations communicating with a larger number of peers or associated with a larger number of NAN device links (NDLs), etc. may transmit beacons earlier in a wake-up window or with a higher probability). Other stations within the NAN may maintain clock synchronization based on the transmitted beacons (e.g., that include recently updated clock information). Additionally or alternatively, a station may signal other stations within a NAN when the station detects disappearance of synchronization beacons (e.g., or loss of clock synchronization). In some cases, the signaling may include requests for the one or more other stations to start or stop beacon transmissions as desired.

Abstract: Aspects of the present disclosure provide techniques for synchronizing clocks in a Neighbor Aware Network (NAN) Data Link (NDL) cluster. An exemplary apparatus includes a processing system configured to communicate with one or more members of a group, that includes the apparatus, according to a first data communication window (DCW) timeline having a first offset relative to a first clock associated with a first network cluster, to detect a beacon transmitted by a device of a second network cluster, wherein the beacon comprises timing information of a second clock associated with the second network cluster, to determine whether to initiate a move of the group to the second network cluster, to generate a frame to initiate the move of the group to the second network cluster, the frame comprising a first indication of the timing information of the second clock, and an interface configured to output the frame for transmission.

Abstract: An apparatus includes a memory and a processor coupled to the memory. The processor is configured to determine a first identifier that corresponds to a data link group identifier of a data link group and to determine a second identifier that corresponds to a device. The processor is further configured to generate an internet protocol (IP) address for a data link interface of the device based on a combination of a data link routing prefix, the first identifier, and the second identifier.

Abstract: Various aspects of the disclosure relate to distributed multiple-input multiple-output (MIMO) communication such as coordinated beamforming or Joint MIMO. In some aspects, distributed MIMO is used to support communication in a cluster of wireless nodes (e.g., access points). A distributed MIMO scheduling scheme as taught herein is used to determine each wireless node (e.g., station) in the cluster that needs to be nulled by another wireless node (e.g., an access point). For example, one of the wireless nodes may obtain signal measurement information from the other wireless nodes and thereby generate a list of wireless nodes (e.g., access points) that need to null one or more wireless nodes (e.g., stations).

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may configure one or more trigger frames, which may include a number of random access resource units (RUs). A number of stations (STAs) may contend to use such random access RUs. Regulation techniques for which STAs may contend for access to random access RUs may include providing that separate subsets of random access RUs may be identified for STAs that are associated and unassociated with the AP. In some implementations, the regulation techniques enable STAs to attempt transmissions using the random access RUs when uplink-limited or if the STA has a non-empty buffer, or combinations thereof. Techniques for acknowledging receipt of an uplink transmission may include transmitting an acknowledgment using a same association identification for the acknowledgment as used in the uplink transmission, and including a STA identifier in a signaling field associated with the acknowledgment.

Abstract: A first neighbor awareness networking (NAN) device may access data network infrastructure and may advertise a service associated with the data network infrastructure to a second NAN device. For example, the first NAN device may announce the service via a service announcement. The second NAN device may subscribe to the service through the first NAN device, and the second NAN device may proxy the service announcement to another NAN device. The other NAN device may also subscribe to the service in response to receiving the service announcement. For example, the second NAN device may operate as a “relay point” to provide the service to the other NAN device.

Abstract: Methods, systems, and devices for wireless communication are described. The described techniques may increase throughput of a wireless network, improve utilization of available channels, or provide other benefits. For example, the ability for a single traffic flow to span across different channels may increase the capacity of the network, may reduce communication latency, etc. In accordance with aspects of the present disclosure, a wireless device supporting multi-link communication may identify an anchor link and one or more supplementary links. For example, the anchor link may provide reliable communications while the supplementary links may provide increased throughput relative to the anchor link As an example, the anchor link may be dedicated for use to communicate management or control information, as well as data, while the supplementary links in the multi-link session may be used to communicate data according to the control and management information transmitted on the anchor link.

Abstract: Methods and systems for coordinating simultaneous transmission by two or more access points over a single channel of a wireless medium are disclosed. In one aspect, a method includes determining, by a first access point, a time when the first access point and a second access point will transmit simultaneously over the channel, and transmitting, by the first access point, over the channel at the time.

Abstract: This disclosure provides systems, methods and apparatuses for selectively acquiring communication frames from a transmitting device capable of formatting the communication frames in accordance with a plurality of PHY formats. In some implementations, a STA may filter or discard duplicate frames received from an AP based, at least in part, on a preference of the STA for one of the plurality of PHY formats. The filtering may be performed at the PHY, without forwarding received communication frames to the media access control layer (MAC) for further processing. In some other implementations, an AP may refrain from sending duplicate frames to a STA based, at least in part, on a preferred frame format of the STA. Still further, in some implementations, the STA may dynamically adjust or update its preferred frame format based on changes in the distance, or channel conditions, between the STA and the AP.

Abstract: In some examples, a method includes generating, at a first device, a paging message including an indication of whether the first device is available for a particular time period during which devices of a data link group of a neighbor aware network (NAN) are configured to operate in an active operating mode. The method also includes sending the message from the first device to one or more devices of the data link group of the NAN.
