Abstract: This disclosure provides methods, devices and systems for sharing resources of a wireless medium. Particular implementations relate more specifically to coordinated AP (CAP) time-division-multiple-access (TDMA) and orthogonal-frequency-division-multiple access (OFDMA) techniques for sharing the time or frequency resources of a transmission opportunity (TXOP). According to such techniques, an AP that wins contention and gains access to the wireless medium for the duration of a TXOP may share its time or frequency resources with other selected APs. To share its resources, the winning AP may partition the TXOP into multiple time or frequency segments each including respective time or frequency resources representing a portion of the TXOP, and allocate each of the time or frequency segments to itself or to one of the selected APs.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication. An example wireless communication device broadcasts a first beacon frame over a first communication link of an access point (AP) multi-link device (MLD) (AP MLD), and broadcasts a second beacon frame over a second communication link of the AP MLD. The first beacon frame indicates transmission of group data over the first communication link, and the second beacon frame indicates transmission of the group data over the second communication link. The wireless communication device transmits the group data, concurrently over the first and second communication links, to one or more wireless stations (STAs). Another example wireless communication device obtains one or more beacon frames indicating buffered group data in an AP MLD for at least the wireless communication device, selects one or more group communication links, and obtains the group data over the one or more selected group communication links.

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: Various aspects of the techniques, methods and devices described in this disclosure relate generally to achieving coexistence between WLAN and P2P networks, and specifically, to coordinated D2D communications. Some aspects particularly involve extending the capabilities of TWT elements transmitted by APs to support periodic reserved access windows during which D2D-enabled wireless devices are permitted to transmit direct wireless communications. Some other aspects relate to sharing time and frequency resources via CAP TDMA or CAP OFDMA techniques, and specifically, to allocating at least some of the time and frequency resources specifically for D2D communications. Some other aspects relate to periodic coordinated access windows during which APs are scheduled to contend but during which D2D devices are not permitted to contend, and specifically, to scheduling a reserved access window within a periodic coordinated access window during which D2D devices may transmit direct communications to other D2D devices despite the permissions associated with the periodic coordinated access windows.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer-readable media, for reporting Quality of Service (QoS) feedback information. A method of wireless communication at an apparatus may include selecting, from a variable number of control fields, one or more control fields for inclusion in a frame, each control field comprising a control identifier field and a control information field. The control identifier field may include an indicator indicating a type of information for communication is QoS feedback information. The control information field may include one or more subfields containing the QoS feedback information. The method may further include generating the frame comprising the selected number of control fields, and outputting the frame for transmission.

Abstract: A method and a system are disclosed for suspending or resuming one or more broadcast-TWT sessions by a first device such as an AP. The method includes the first device obtaining a TWT beacon frame. The method also includes the first device adding one or more TWT information fields to the TWT beacon frame. The method further includes the first device transmitting the TWT beacon to one or more stations to suspend the one or more broadcast-TWT sessions.

Abstract: This disclosure provides systems, methods, and apparatuses for dynamically changing a primary communication link on which wireless devices contend for access to a shared wireless medium. An access point (AP) may monitor the channel conditions on a primary link and one or more secondary links of a multi-link environment, and may signal a change in the primary link (such as to one of the secondary links) when one or more conditions are satisfied. The primary and secondary links may be assigned on a per-client basis. Thus, the primary or secondary links of a particular STA may be different than those of other STAs associated with the same AP. In some aspects, each STA may monitor the channel conditions on its own primary and secondary links, and may signal a change in its primary link (such as to one of its secondary links) when one or more conditions are met.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a STA. The STA receives a management frame including a first broadcast TWT parameter set associated with a broadcast TWT schedule identified by a first ID. The first broadcast TWT parameter set identifies a first time duration associated with a validity of the first broadcast TWT parameter set. The first broadcast TWT parameter set identifies at least four bits indicating the first time duration. In addition, the STA determines the validity of the first broadcast TWT parameter set based on the received first time duration. The STA may refrain from monitoring subsequent management frames (e.g., in order to sleep, to enter into a power saving mode, or to monitor other devices) that include the first broadcast TWT parameter set for a second time duration based on the first time duration.

Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for signaling communication characteristics between wireless devices. In one implementation, a first wireless communication device may determine that a trigger frame will allocate one or more resource units for communications by one or more stations unassociated with the first wireless communication device. The first wireless communication device adds an indication of a reference channel associated with the first wireless communication device or a basic service set (BSS) color indication to the trigger frame. The trigger frame is output for transmission to one or more other wireless communication devices. A receiving device may then identify the reference channel or the BSS color indication from the trigger frame and use this information for communication with the first wireless communication device.
