Abstract: This disclosure provides methods, devices and systems for using a pseudonym service set identifier (pSSID) for access point (AP) and station (STA) privacy. For example, a pSSID is included by a STA or AP in place of a persistent SSID for over the air communications used for various functions (such as for the STA to determine the SSID of the AP before connecting to the AP). The pSSID is generated using a hash function that is defined at both the AP and the STA. An input to the hash function includes the SSID. Other inputs may include a temporary media access control (MAC) address of the device generating the pSSID, a time value associated with a time when the pSSID is generated, or a location value associated with a position measurement of the device generating the pSSID.

Abstract: This disclosure provides methods, devices and systems for protecting latency-sensitive communications, during restricted target wake time (r-TWT) service periods (SPs), from non-legacy STAs that do not support r-TWT operation. Some implementations more specifically relate to preventing STAs that are not members of an r-TWT SP from acquiring transmit opportunities (TXOPs) that would otherwise overlap with the start of the r-TWT SP. In some implementations, the AP may require all non-legacy STAs associated with its basic service set (BSS) to support r-TWT operation. In some other implementations, the AP may attempt to capture a wireless channel associated with the r-TWT SP within a fixed period preceding the r-TWT SP. In some other implementations, the AP may require all associated STAs to transmit a request-to-send (RTS) frame when attempting to acquire a TXOP. Still further, in some implementations, the AP may limit the duration of TXOPs acquired by non-member STAs.

Abstract: This disclosure provides methods, devices and systems for communicating over multiple links, for example, indicating buffered units (BUs) per traffic identifier (TID) for transmission to multi-link devices (MLDs). One innovative aspect of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method can be performed, for example, by a non-access point (non-AP) MLD. The non-AP MLD can receive an indication of an association identifier (AID) associated with the non-AP MLD, wherein the indication of the AID indicates whether an AP has BUs for the non-AP MLD, determine one or more links associated with one or more TIDs based on a mapping of a plurality of TIDs, including the one or more TIDs, to a plurality of links, including the one or more links, receive the BUs associated with the one or more TIDs from the AP on the determined links.

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: One innovative aspect of the subject matter described in this disclosure may be implemented in a method for wireless communication. The method may be performed, for example, by a first multi-link device (MLD), that includes a first station (STA) and a second STA, to generate and provide block acknowledgment (BA) status reports for Medium Access Control (MAC) Protocol Data Units (MPDUs) transmitted by the first STA of the first MLD and the second STA of the first MLD. Another innovative aspect of the subject matter described in this disclosure may be implemented in a method for wireless communication. The method may be performed, for example, by a logical entity of a first MLD to receive and process a BA status report.

Abstract: This disclosure provides systems, methods, and apparatuses for associating a wireless communication device such as a wireless station (STA) of a STA multi-link device (MLD) with an access point (AP) MLD that includes a first AP associated with a first communication link of the AP MLD and includes one or more secondary APs associated with one or more respective secondary communication links of the first AP MLD. The first AP includes one or more virtual APs, and the first AP and the one or more virtual APs of the first AP belong to a first multiple basic service set identifier (BSSID) set associated with the first communication link. The AP MLD transmits a frame including a first element carrying discovery information for the first AP and the one or more virtual APs belonging to the first multiple BSSID set, and including a second element carrying discovery information for the one or more secondary APs of the first AP MLD associated with the one or more respective secondary communication links of the first AP MLD.

Abstract: One innovative aspect of the subject matter described in this disclosure may be implemented in a method for wireless communication. The method may be performed, for example, by a first entity of a multi-link device (MLD) to receive a first control frame transmitted on a first wireless link and set, in response to receiving the first control frame, a network allocation vector (NAV) for each link of multiple wireless links of the first MLD based on a duration field in the first control frame.

Abstract: This disclosure provides methods, devices and systems for wireless communication, and particularly, methods, devices and systems for multi-link operation. In some aspects, a first WLAN device (such as a non-AP STA) may establish with a second WLAN device (such as an AP) a multi-link association by which the first WLAN device can simultaneously transmit information to the second WLAN device via a first wireless communication link and a second wireless communication link. The first WLAN device may coordinate contention for the first wireless communication link by a first WLAN interface of the first WLAN device to be concurrent with contention for the second wireless communication link by a second WLAN interface of the first WLAN device.

Abstract: With multiple communication channels available and range extenders, a number of paths may be available for communicating traffic in a wireless network. Traffic on paths in the wireless network may be load balanced to improve channel utilization and/or relieve an overloaded communication channel. To load balance the traffic, a first AP may determine candidate paths between a first AP and a client device, wherein at least one of the candidate paths traverses a second AP. The AP may determine available bandwidths of the candidate paths based, at least in part, on availability of communication channels of the candidate paths. The AP may steer a portion of the wireless network traffic of the client device to a first of the candidate paths based, at least in part, on the available bandwidths.
