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: Methods, systems, and devices for wireless communications are described. An access point (AP) may identify receiving wireless devices for which to send a wake-up radio (WUR) frame. The AP may obtain a basic service set identifier (BSSID) for the AP that is associated with (or intends to be associated with) the receiving wireless devices, the BSSID being known by the receiving wireless devices. The AP may perform a hashing function to the BSSID to obtain a hashed BSSID. The AP may use a first portion of the hashed BSSID as a first identifier. The AP may generate the WUR frame for transmission with an address identifier field that includes either the first identifier or a second identifier. The second identifier nay be based at least in part on the first identifier. The AP may transmit the WUR frame to the receiving wireless devices.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In an aspect, the apparatus is configured to receive at least one frame from at least one wireless device and to generate a BA frame that may include a block ACK bitmap based on the received at least one frame. The BA frame may include a fragment number field and a bitmap length indicator within the fragment number field that indicates a length of the block ACK bitmap within the BA frame. The apparatus may be configured to transmit the generated BA frame to the at least one wireless device.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus is configured to determine a communication deferral policy within a BSS associated with the apparatus. The apparatus is configured to receive a message from a second wireless device. The apparatus is configured to determine a message type of the message. The apparatus is configured to determine whether the message is associated with an OBSS based on the determined message type. The apparatus is configured to determine whether to defer communications based on the communication deferral policy, the message type, and whether the message is associated with the OBSS.

Abstract: Methods and systems for accessing networks prohibit uncontrolled communications over a designated network. In some aspects, a method of controlling network access is disclosed. The method comprises transmitting, by a first access point, a first beacon over a first network to a station, the first beacon including information allowing the station to associate with the first access point. The method also comprises receiving a probe request at the first access point over the first network from the station, the probe request including a request for rules for associating with a second network. The method additional comprises generating a probe response to include the rules regarding associating with the second network, wherein the rules do not permit uncontrolled communications over the second network. The method further comprises transmitting the probe response from the first access point to the station over the first network.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a multi-link aggregation capability (e.g., a capability to transmit in parallel over multiple wireless links), and may transmit an indication of such capability to another wireless device. The indication may be included in an information element (e.g., a multi-band element) of a transmission frame. For example, the indication may be included in a multi-band element of a beacon, of association signaling, of probe signaling, of an add block acknowledgement (ADDBA) request, etc. The indication sent over one of the wireless links may include information for some or all the multiple links supported for multi-link aggregation. This information may include media access control (MAC) address, channel information, operating class, security information, etc. for each link. Such multi-link aggregation information may be used, for example, for establishment of improved block acknowledgment (BA) sessions between wireless devices.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an apparatus is configured transmit, to a set of stations, a trigger frame that indicates a set of RUs for uplink and/or downlink transmission available to each station of the set of stations. The trigger frame may be a request for feedback on the set of RUs from each station. The apparatus may be configured to receive from each station a response frame over an uplink resource based on the transmitted trigger frame. The response frame may include the feedback on the set of RUs and may be received independent of a channel condition associated with the uplink resource. The feedback may be an ordered list of RUs based on the set of RUs.
