Abstract: This disclosure provides methods, devices and systems for synchronized channel access. Some implementations more specifically relate to facilitating coexistence among wireless communication devices that support synchronized channel access and those that do not. A group of access points may schedule periodically recurring, synchronized channel access periods by periodically transmitting quiet elements. The quiet elements establish recurring quiet periods during which legacy devices are not permitted to transmit. In some implementations, an access point may transmit one or more quiet override elements each associated with a respective quiet element and indicating to other access points supporting synchronized channel access that they are permitted to contend for access during the respective quiet period. In some other implementations of synchronized channel access, an access point supporting synchronized channel access that wins contention after one or more consecutive synchronized channel access periods during which no other synchronized access points won contention, may be entitled to an extended TXOP.

Abstract: This disclosure provides methods, components, devices and systems for use of a reinforcement learning (RL) model to obtain one or more parameters associated with a channel access procedure. Some aspects more specifically relate to mechanisms according to which a wireless communication device may receive information associated with the RL model and transmit a protocol data unit (PDU) during a slot that is based on an output of the model. The wireless communication device may use the RL model to perform a distributed channel access procedure in accordance with the information and may further transmit the PDU, during the slot that is based on the output of the RL model, in accordance with the distributed channel access procedure. The information associated with the RL model may indicate or configure the RL model or may indicate whether the wireless communication is allowed to retrain the RL model.

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: Methods, systems, and devices for wireless communications are described. A wireless device that operates in a wireless local area network may include an auxiliary radio and a main radio and may operate in both an auxiliary radio mode and a main radio mode. The auxiliary radio may support both transmitting and receiving or may support receiving only. The wireless device may indicate parameters associated with an auxiliary radio mode and/or with transitioning from the auxiliary radio mode to a main radio mode. The auxiliary radio may perform additional functions while the wireless device communicates with a second wireless device on a wireless link using the main radio. For example, the auxiliary radio may monitor channel metrics of the wireless link, receive and/or transmit control communications with the second wireless device, receive and/or transmit high importance data communications, or scan for and/or initiate connections via other wireless channels.

Abstract: This disclosure provides systems, methods, and apparatus for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) receives a request frame from a wireless station (STA) associated with a client device via a peer-to-peer (P2P) link, the request frame indicating the STA intends to exchange P2P communications with the client device during a r-TWT SP scheduled on a wireless medium. The AP obtains a transmission opportunity (TXOP) on the wireless medium during the r-TWT SP, the request frame identifying the client device. The AP transmits a trigger frame on the wireless medium responsive to obtaining the TXOP, the trigger frame allocating a portion of the obtained TXOP for P2P communications between the STA and the client device, wherein at least one of the response frame or the trigger frame indicates a Network Allocation Vector (NAV) exception for the client device.

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: Methods, systems, and devices for wireless communications are described. A first wireless device and a second wireless device (e.g., access points, stations) may support transmission opportunity (TXOP) sharing procedures. The second wireless device may transmit a frame indicating a capability of the second wireless device to support one or more triggered TXOP sharing modes. The second wireless device may transmit an indication (e.g., a frame) indicating to change support for the triggered TXOP sharing modes based on the capability. The change may indicate to suspend, resume, disable, or enable the triggered TXOP sharing modes. For example, the second wireless device may transmit an indication to suspend support of a first triggered TXOP sharing mode that enables the second wireless device to perform peer-to-peer transmissions. Accordingly, the first wireless device may trigger the second wireless device to communicate according to the supported triggered TXOP sharing modes.

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 enhanced bandwidth puncturing. Some implementations more specifically relate to punctured channel indications that support channel puncturing over a range of bandwidths achievable in accordance with the Institute of Electrical and Electronics Engineers (IEEE) 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an access point (AP) may communicate static punctured channel information to each associated wireless station (STA) in its BSS. In some other implementations, a transmit opportunity (TXOP) holder may communicate dynamic punctured channel information to a TXOP responder with which it intends to communicate. Still further, in some implementations, the TXOP responder may communicate additional punctured channel information to the TXOP holder responsive to the dynamic punctured channel information.
