Abstract: This disclosure provides methods, components, devices and systems for packet duplication for data frames in a wireless local area network (WLAN). Some aspects more specifically relate to decoding duplicate packets that include data frames. An access point (AP) may transmit two or more physical layer protocol data units (PPDUs) that are duplicates of each other while operating in a duplicate data packet mode. A station (STA) may include one or more decoders configured to decode the duplicate PPDUs cumulatively or separately based on a decoding mode. The AP and the STA may exchange frames to dynamically enable or disable the duplicate data packet mode. The duplicate PPDUs may include one or more bits configured to indicate that the PPDU is a duplicate. The STA may decode at least one of the duplicate PPDUs and transmit a feedback message responsive to at least a portion of one of the duplicate PPDUs.

Abstract: This disclosure provides methods, components, devices and systems for channel access techniques in a multi-hop framework for ultra-high reliability (UHR). Some aspects more specifically relate to a transmission opportunity (TXOP) sharing mechanism according to which wireless communication devices can relay data frames along multiple hops within a same TXOP, a coordinated medium access scheme associated with relaying data frames between a root access point (AP) and a wireless station (STA) via multiple service periods, and various signaling mechanisms and frame formats according to which wireless communication devices can exchange or negotiate information associated with a coordinated medium access scheme. In some implementations, a coordinated medium access scheme may be associated with multiple time epochs (each associated with a service period) and differentiated channel access across the multiple time epochs may facilitate the relay with or without TXOP sharing within the associated service periods.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for signaling parameters for peer-to-peer communications in a wireless network. One aspect provides a method for wireless communications at an access point (AP). The method generally includes: obtaining, from an access point (AP), a transmission opportunity (TXOP) sharing trigger indicating a duration in which a TXOP is shared by the wireless station and one or more other devices; relaying, to the one or more other devices, information identifying parameters for wireless communications between the wireless station and the one or more other devices; and during the TXOP, communicating with the one or more other devices based on the parameters for wireless communications between the wireless station and the one or more other devices.

Abstract: This disclosure provides methods, devices and systems for transmitting and receiving, between an access point (AP) and one or more stations (STAs) in a basic service set (BSS), within a 3.5 GHz bandwidth. In some examples, the AP may output, for transmission to a network node, a request for channel resources comprising an indication of one or more channel resources within a spectrum. In another example, the AP may obtain, from the network node, a response to the request, the response providing the apparatus with access to the indicated one or more channel resources within the spectrum.

The processor(s) is configured to transmit a first message indicating support for machine learning by the first WLAN device. The processor(s) is also configured to receive, from a second WLAN device, a second message. The second message indicates support for one or more machine learning model type(s) by the second WLAN device. The processor(s) is configured to activate a machine learning session with the second WLAN device based at least in part on the second message. The processor(s) is also configured to receive, from the second WLAN device, machine learning model structure information and machine learning model parameters during the machine learning session.

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.
