Abstract: An apparatus for wireless communication is disclosed. The apparatus includes a processing system configured to generate a request for information about one or more neighboring wireless nodes; and an interface configured to output the request for transmission and, thereafter, obtain a response to the request. The processing system is further configured to filter, based on a response to the request, a list of network resources; and generate a report comprising the filtered list of network resources.

Abstract: In some examples, a method includes receiving, at a second device of a data link group of a neighbor aware network (NAN), a message including an indication of whether a first device corresponding to a particular service is available during a particular time period during which devices of the data link group are configured to operate in an active operating mode. The method also includes transitioning to a low-power operating mode during one or more transmission windows corresponding to the particular time period in response to determining that the first device is unavailable during the particular time period.

Abstract: Methods and systems for sounding a wireless network are disclosed. In one aspect, a method includes receiving, by an access point a message including a beamforming report from a device. The device may be a station that is outside a basic service set of the access point. The method also includes transmitting a message to the device based on the beamforming report. For example, in some aspects, the access point may utilize the beamforming report to perform a coordinated beamforming, multi-access point transmission or a multi-access point MIMO transmission. In some aspects, the access point may transmit an interference nulling signal to the device based on the beamforming report. The nulling signal compensates for another simultaneous transmission by the access point that interferes with the device's reception of a message from an access point with which the device is associated.

Abstract: Methods, systems, and devices for wireless communication are described. Wireless devices may support parallel communications over multiple wireless links, which may benefit a wireless system in terms of throughput and latency (among other benefits). However, such systems may experience increased system complexity, which may in some cases mitigate some of the benefits provided by the parallel communication links. The described techniques provide for aggregation architectures that address various such complexities. For example, devices communicating in accordance with the described techniques may format data to be transmitted into a set of data units that are allocated to a communication link based on various factors described herein. Correspondingly, a device that receives the data packets may reorder the packets in accordance with the described techniques.

Abstract: Methods, systems, and devices for multi-link wireless communication are described. A block acknowledgment (BA) agreement (e.g., a multi-link BA session) may be established based on exchanged multi-link capability information (e.g., a BA window size, BA scoreboarding information, one or more wireless link identifiers, etc.). In some cases, a BA agreement may be established across some or all of the multiple links. In other cases, a BA agreement may be established on a per-link basis. The BA agreement may further establish one or more sets of sequence numbers, as well as scoreboarding techniques used by the transmitting wireless device for the BA session. The wireless device may then transmit packets to another wireless device using multiple links, and receive a BA with acknowledgement information accounting for the transmitted packets according to the established BA agreement. BAs may be transmitted on one link or on multiple links by the receiving device.

Abstract: Methods and systems provide implementations for distributed MIMO communication. In one aspect, a method includes receiving a network message including data indicative of user data for transmission by a first access point to a first station over the wireless network prior to the transmission, generating precoded second data for transmission to the first station based on the data indicative of the user data, and transmitting, the precoded data to a third device. In some aspects, the precode data is transmitted by a second access point of a basic service set different than that of the first station to the first station as part of a distributed MIMO communication. In some other aspects, the precoded data is transmitted by a cluster controller to another access point having a basic service set different than that of the first station. The other access point may then transmit a signal based on the precode data to the first station simultaneously with the fist access point also transmitting to the first station. The two transmissions may form a portion of a distributed MIMO communication.

Abstract: Methods, systems, and devices for wireless communications are described, including identifying a first attribute value associated with a first access point; receiving a second attribute value; and determining that the first attribute value associated with the first access point is the same as the received second attribute value. An attribute value may be an n-bit value, where n is an integer. The n-bit value may identify a BSS color. The n-bit value may, additionally or alternatively, indicate other BSS color information such as a BSSID, ESSID, SSID, or a combination thereof. It is helpful when devices detect BSS attribute value (e.g., BSS color, BSSID, MAC address, ESSID) overlap and notify other associated devices (e.g., STAs, APs) of this overlap so that a device may cease using an attribute value for power save or channel access decisions, and facilitate attribute value adjustment and correction to eliminate a BSS collision.
