Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide that an access point (AP) or a station (STA) may identify, from a set of channels in a radio frequency spectrum band, a subset of discovery channels. The discovery channels may be designated for discovery signaling for device association. An AP may transmit discovery information for associating with a STA over a discovery channel from the subset of discovery channels. In some examples, the AP may receive a probe request from a STA operating in an active scanning mode, and may transmit the discovery information in a probe response. In some examples, the AP may transmit the discovery information in a periodic signal, such as a beacon, to a STA operating in a passive scanning mode. The AP may receive an association request and associate with the STA.

Abstract: Features related to providing feedback corresponding to a portion of a data frame while another portion of the data frame is being received are described. In an aspect, a first device may transmit, to a second device, at least one MPDU of a plurality of MPDUs within the data frame via a data channel, and receive feedback corresponding to the at least one MPDU in a feedback channel while at least a first MPDU of the remaining MPDUs within the data frame is being transmitted. In another aspect, a first device, e.g., receiver of data frame, may receive, from a second device, at least one MPDU of a plurality of MPDUs within a data frame, and transmit feedback corresponding to the at least one MPDU while at least a first MPDU of the remaining MPDUs within the data frame is being received.

Abstract: Aspects described herein relate to requesting and/or reporting channel feedback. A request for channel feedback can be generated by an access point, where the request includes an indicator specifying that the request uses a first format different from a second format, where the indicator corresponds to a bit of a station (STA) information field defined by the second format. The access point can transmit, and a STA can receive, the request for channel feedback.

Abstract: Methods, systems, and devices are described for wireless communications. A wireless device may advertise communication parameters for a particular frequency band over another frequency band. In one example, a wireless device generates multi-band wrapper information element or a neighbor report information element, which may include one or more subelements, each conveying communication information for a particular frequency band. The wireless device may include the multi-band wrapper information element or the neighbor report information element in a management frame and may transmit the management frame over a first frequency band. Another wireless device may receive the management frame over the first frequency band and may obtain the communication information for other frequency bands from the included multi-band wrapper information element. In some cases, a subelement carries communication information that is sufficient for the receiving device to directly associate with the transmitting device over the other frequency bands.

Abstract: Aspects of the present disclosure relate to a wireless device including one or more processors and a memory storing processor-readable instructions that, when executed by the one or more processors, causes the wireless device to perform operations. The operations include receiving a first message indicating a reuse transmission opportunity associated with a downlink transmission from a first device to a second device. The operations further include determining to participate in the reuse transmission opportunity based at least in part on the downlink transmission. The operations further include, during the reuse transmission opportunity, transmitting uplink communications to the first device concurrently with the downlink transmission from the first device to the second device in the same frequency channel.

Abstract: This disclosure provides systems, methods, and apparatuses for operating a wireless station in a multiple basic service set identifier (BSSID) set including a transmitted BSSID (Tx BSSID) and a number of non-transmitted BSSIDs (non-Tx BSSIDs). In some implementations, the wireless station may receive a trigger frame containing a number of association identifier (AID) values based on a group AID mapping contained in a partial virtual bitmap of a traffic indication map (TIM) element, and may determine whether the trigger frame allocates one or more random resource units (RUs) for use by the station based on one or more of the AID values contained in the trigger frame.

Abstract: Distributed MIMO communication utilizes multiple access points within a cluster. Methods and systems for access point discovery provide for formation of a cluster to support the distributed MIMO communication. In one aspect, a method includes generating, by a first access point, a first message indicating the first access point has distributed MIMO capability and transmitting, by the first access point, the first message on a wireless network. The method further includes receiving, by the first access point, a second message from a second access point, the second message identifying a cluster and determining, by the first access point, to participate in the identified cluster in response to the second message.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. In one aspect, a first station discovers a second station capable of providing a service of interest to the first station. The second station is one of a plurality of stations participating in a NAN data link network that provides the service of interest and supports communication over a NAN data link channel without beaconing. The second station is discovered through communication over a NAN channel supported by a plurality of neighborhood stations forming a NAN network. The NAN channel has a beaconing operation that provides synchronization. After discovery of the second station, the first station communicates with the second station over the NAN data link channel, to obtain data corresponding to the service of interest.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for enabling an immediate response. In this manner, issues can be avoided where data carried by the last symbol of a frame cannot be entirely decoded by a receiver within a deadline for generating an immediate response. One example method for wireless communications by a first apparatus generally includes determining at least one constraint for communicating with a second apparatus; generating a frame that solicits a response; and outputting the frame for transmission to the second apparatus, wherein at least a last symbol of the frame is transmitted in a manner determined by the constraint to allow the second apparatus to transmit the response within a determined period.
