Abstract: This disclosure provides methods, devices and systems that facilitate mobility of wireless communication devices configured for multi-link operation (MLO). Particular aspects more specifically relate to facilitating fast basic service set (BSS) transitions by wireless communication devices that support MLO. For example, some aspects provide support for station (STA) multi-link device (MLD) roaming between access point (AP) MLDs, from an AP MLD to a non-MLO AP, or from a non-MLO AP to an AP MLD. In some aspects, a STA MLD may be configured to use a medium access control (MAC) service access point address (MAC-SAP address) of the AP MLD when re-associating or communicating with a legacy AP or with an AP MLD. In such aspects, the MAC-SAP address may be used by all STAs of the non-AP MLD for fast BSS transitions.

Abstract: This disclosure provides systems, methods, and apparatus for wireless communications. In one aspect, an apparatus may obtain, for a first access point (AP), a first service set identifier (SSID) associated with single-link communications and obtain, for a second AP, a second SSID associated with multi-link communications. The apparatus may obtain, from a wireless communication device, a management frame include a multi-link operation information field that carries a first SSID and obtain a multi-link indication for the wireless communication device based, at least in part, on the first SSID, the multi-link indication indicating whether the wireless communication device includes AP capable of link aggregation, and selectively associate with the wireless communication device based on the multi-link indication.

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: Certain aspects of the present disclosure provide a method of wireless communications by a first multi-link device (MLD). The method generally includes establishing multiple links with at least one second MLD, obtaining network coded packets over at least one of the multiple links, decoding the network coded packets, based on a network decoding algorithm, to recover one or more uncoded packets, generating feedback based on the decoding, and outputting, for transmission, the feedback to the at least one second MLD.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network entity may generate a transmit power envelope (TPE) element that includes fields that indicate maximum transmit powers for bandwidth sizes, including an extension field for a bandwidth whose size is greater than 160 MHz or for a bandwidth with channel puncturing, based at least in part on detecting a difference between a first bandwidth size configured for a first device operation mode and a second bandwidth size configured for a second device operation mode. The network entity may transmit the TPE element. Numerous other aspects are described.

Abstract: This disclosure provides methods and devices for managing the allocation of resources for uplink (UL) and downlink (DL) transmissions associated with a scheduled time period. In some implementations, a wireless station (STA) transmits, to an access point (AP), a request frame indicating a bandwidth or a quantity of spatial streams (or both) for the UL transmissions, and indicating a bandwidth or a quantity of spatial streams (or both) for the DL transmissions. In some instances, the request frame also may indicate the STA's intention to transmit UL data as duplicates carried on different communication links. The STA receives a trigger frame indicating that the STA is scheduled to transmit or receive data during the time period. The STA transmits data to, or receives data from, one or more other devices during the time period.

Abstract: Certain aspects of the present disclosure relate to wireless communications and, more particularly, to multi-link communications. A method that may be performed by an access point (AP) multi-link device (MLD) includes establishing a plurality of links for communication with a non-AP MLD, wherein one or more non-AP MLDs, including the non-AP MLD, communicate with the AP on each link of the plurality of links and taking one or more actions designed to ensure that the non-AP MLD is able to receive a group addressed frame. The non-AP MLD is operating in an enhanced multi-link single radio (EMLSR) mode.

Abstract: A wireless station (STA) operating as a non-simultaneous transmit-receive (NSTR) soft access point (AP) multi-link device (MLD) associated with a primary link and a non-primary link determines that the non-primary link is unavailable, and transmits, on only the primary link, a frame carrying an indication of the unavailability of the non-primary link. The NSTR softAP MLD may set a Do Not Transmit (DNT) bit to a value of 1 and may operate as a single-link device on the primary link based on the unavailability of the non-primary link. In some instances, the NSTR softAP MLD determines that the non-primary link is available while operating as the single-link device on the primary link, resets the DNT bit based on the availability of the non-primary link, and transmits the reset DNT bit in another frame on only the primary link.

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: Certain aspects of the present disclosure provide techniques for handling direct link communications in multi-link systems. An example method generally includes transmitting, to a first wireless station via a direct link between the first wireless station and one or more second wireless stations affiliated with a multi-link device (MLD), a data frame comprising a transmitter address field set to an address of the MLD, which is one of a plurality of addresses associated with the MLD and the second wireless stations being affiliated with the MLD for multi-link operations. The method also includes communicating with the first wireless station via the direct link.
