Abstract: This disclosure provides methods, devices and systems for wireless communication, and particularly for address translation during multi-link operation in a wireless local area network (WLAN). The method may include establishing one or more wireless communication links with a station (STA) including a first wireless communication link. The method may include receiving, via the first wireless communication link, a first frame including a first address field that includes a first link media access control (MAC) address associated with the STA. The method may include determining that the STA is associated with a first network MAC address. The method may include removing the first link MAC address from the first address field of the first frame, and inserting the first network MAC address of the STA in a second address field of the first frame. The method may include transmitting the first frame to a first local area network (LAN) device.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a hybrid automatic repeat request (HARQ) protocol in a wireless local area network (WLAN). In some aspects, a first WLAN device may transmit a first HARQ frame to a second WLAN device. The first WLAN device may determine whether a first feedback message received from the second WLAN device includes HARQ acknowledgement information or non-HARQ acknowledgment information. The first feedback message may be a HARQ Block Acknowledgement (H-BA) message having a multi-station Block ACK (M-BA) frame format that includes HARQ acknowledgment information. The first WLAN device may transmit a second HARQ frame to the second WLAN device in response to determining the first feedback message includes the HARQ acknowledgment information. The first WLAN device may transmit a non-HARQ frame in response to determining the first feedback message includes non-HARQ acknowledgement information.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for signaling aggregated control information in a wireless communication network. A frame format may include an aggregated control (A-Control) field. In one aspect, the A-Control field may be variable-length to support signaling multiple types of control information. In some implementations, an access point may manage multiple links (multi-link). The A-Control field may be structured to include multi-link control information. This disclosure includes multiple options for extending an A-Control field. Furthermore, a receiving device may acknowledge the A-Control field using various techniques disclosed herein.

Abstract: Certain aspects of the present disclosure provide an apparatus for wireless communication. The apparatus generally includes a processing system configured to generate a message comprising coordination information, wherein the apparatus is associated with a first AP, the message to be used for coordinated communications by the first AP and a second AP, wherein the first AP and the second AP are associated with different basic service sets (BSSs), and an interface configured to output the message for transmission during a networking coordination window of a networking cluster.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for preventing or reducing cross-network interference associated with a coordinated transmission on a wireless channel. A first access point (AP) of a first basic service set (BSS) and a second AP of a second BSS can concurrently use the wireless channel using a coordinated transmission during a portion of a transmission opportunity (TXOP). The TXOP owner (such as the first AP) may allocate a resource assignment to the second AP such that the resource assignment is conditionally available for use by the second AP in a coordinated transmission. The condition may prevent the resource assignment from being used by the second BSS when its use would cause interference to the first BSS. The condition may be based on a transmit power for downlink communication or uplink communication in the second BSS.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for implementing conditional inheritance in a management frame for two or more basic service sets (BSSs). In one aspect, an apparatus may be configurable to provide functions of a first virtual access point (VAP) corresponding to a first BSS and a second VAP corresponding to a second BSS. The apparatus may determine a first BSS identifier (BSSID) profile for the second VAP by customizing one or more management elements of management information of the first VAP. The apparatus may configure a first non-inheritance element of the first BSSID profile associated with the second VAP to indicate usage of at least one management element of the management information by the second BSS associated with the second VAP is disabled. The apparatus may generate a management frame that comprises at least the first BSSID profile for transmission.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for enabling a neighboring access point (AP) to reuse communication resources that are used by an existing spatial reuse group (SRG). In one aspect, an SR element including SR information can be generated. The SR information may indicate that a first group of STAs associated with a second AP may reuse resources of a wireless medium over which packets are transmitted by a second group of STAs associated with the first AP and may indicate a permitted OBSS threshold value for reuse of the resources over the first AP. In some implementations, a wireless apparatus may transmit the SR element that includes the SR information.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for an AP. The AP determines a time duration associated with a validity of a first broadcast TWT parameter set associated with a broadcast TWT schedule identified by a first ID. The AP generates the first broadcast TWT parameter set to identify the determined time duration. The first broadcast TWT parameter set includes at least four bits identifying the determined time duration. The AP transmits a management frame including the generated first broadcast TWT parameter set. The time duration may indicate a number of intervals for which the first broadcast TWT parameter set is valid. Each interval of the intervals may be a beacon interval corresponding to a beacon frame, or may be a DTIM interval corresponding to a beacon frame that includes a DTIM.
