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: 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 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), an indication of a puncturing event. In some examples, the transmitting and receiving may use non-legacy elements configured to provide information about the puncturing event. In certain aspects, the disclosure provides methods for transmitting and receiving, between the AP and one or more STAs, an indication of an operating band switch. In some examples, the transmitting and receiving may use non-legacy elements configured to provide information about the operating band switch.

Abstract: This disclosure provides methods, devices and systems for providing energy detection based resolution in radio access technologies. In one aspect, a wireless communication device may include a first energy detection threshold (EDT) to identify a transmission opportunity in an unlicensed frequency band. The wireless communication device may detect a second wireless communication device having a second EDT to identify the transmission opportunity, the second EDT being greater than the first EDT. The wireless communication device may, based on detection of the second wireless communication device having the second EDT, modify a transmission configuration of the first wireless communication device.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for coordinated scheduling of service periods (SPs). In some aspects, an access point (AP) may receive timing information indicating an SP associated with an overlapping basic service set (OBSS) and may transmit, to its associated STAs, coordinated timing information indicating the timing of the SP in relation to its timing synchronization function (TSF) timer. In some aspects, the AP may adjust the timing information to account for an offset between its TSF timer and a TSF timer associated with the OBSS. In some other aspects, the AP may synchronize its TSF timer with the TSF timer associated with the OBSS. The AP may further communicate with the STAs based on the coordinated timing information. For example, the AP may schedule communications with the STAs to be orthogonal to communications in the OBSS during the SP.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) may transmit a packet, at the beginning of a restricted TWT SP, that signals all non-member wireless stations (STAs) to defer access to the wireless medium for at least a threshold duration. Upon receiving the packet, any non-member STAs that are associated with the AP may set their network allocation vectors (NAVs) according to the duration indicated by a duration field of the received packet. In some implementations, low-latency STAs that are members of the TWT SP may not set their NAVs according to the duration field of the received packet. Instead, the low-latency STAs may access the wireless medium before the NAVs associated with the non-member STAs expire.

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: This disclosure provides methods, devices and systems for protecting latencysensitive communications during restricted target wake time (r-TWT) service periods (SPs). Some implementations more specifically relate to coordinated scheduling of r-TWT SPs between OBSSs. In some aspects, a first AP may coordinate with a second AP in scheduling r-TWT SPs so that latency-sensitive traffic in a first BSS does not interfere or collide with latency-sensitive traffic in a second BSS overlapping the first BSS. In some implementations, the first and second APs may schedule their respective r-TWT SPs to be orthogonal in time. In some other implementations, the first and second APs may schedule their r-TWT SPs to overlap in time, while allocating coordinated resources to concurrent or overlapping latency-sensitive traffic in the first and second BSSs (such as in accordance with one or more multi-AP coordination techniques).

Abstract: A wireless station (STA) operating as a non-simultaneous transmit-receive (NSTR) soft access point (AP) multi-link device (MLD) is associated with a primary link and a non-primary link. The NSTR softAP MLD transmits, on only the primary link, a frame including a complete profile of the primary link and indicating a complete profile of the non-primary link. The respective complete profiles of the primary link and the non-primary link each include capabilities, operation parameters, and other discovery information. The frame can include fields and elements that carry the complete profile of the primary link, and can include a multi-link (ML) element that indicates the complete profile of the non-primary link. The NSTR softAP MLD can receive or determine an update to the operation parameters of the non-primary link, and can transmit, on the primary link, an indication of the update to the operation parameters of the non-primary link.

Abstract: This disclosure provides systems and methods for requesting wireless resources for peer-topeer (P2P) communications. In some implementations, a wireless communication device transmits a frame over a wireless medium to an access point (AP), the frame including a medium access control (MAC) header carrying a request for the AP to allocate part of a transmission opportunity (TXOP) for P2P communications between the wireless communication device and a client device. The wireless communication device receives a trigger frame allocating a portion of the TXOP for the P2P communications, and transmits or receives P2P data to or from the client device over the wireless medium during the allocated portion of the TXOP. In some instances, the MAC header of the frame includes a Quality-of-Service (QoS) Control field carrying the request. In some other instances, the MAC header of the frame includes an Aggregated-Control (A-Control) subfield carrying the request.
