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: 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.

Abstract: Techniques are provided for broadcast target wake time (TWT) indication in broadcast probe response and FILS discovery frames to aid unassociated wireless stations (STAs). Since broadcast probe response and/or FILS discovery frames are present to aid an unassociated STA discover an AP, an AP may advertise broadcast TWT in these frames when the AP intends to include at least one random access (RA) resource unit (RU) with AID12 set to 2045 (for unassociated STAs). In an aspect, an AP can include the broadcast TWT element in a broadcast probe response frame if a trigger frame (TF) in the TWT service period (SP) is to include at least one RA RU with AID12 set to 2045. In another aspect, an AP can include broadcast TWT element in a FILS discovery frame if the TF in the TWT SP is to include at least one RA RU with AID12 set to 2045.

Abstract: Techniques are provided for extending a beacon request mechanism in IEEE 802.11k for spatial reuse. Particularly, in order to facilitate spatial reuse, features of the present disclosure allow an access point (e.g., a high efficiency access point or HE AP) to request information regarding neighboring APs from one or more associated STAs such that the AP may determine whether any of the neighboring APs are part of the same enterprise or spatial reuse group (SRG) as the AP based on the basic service set (BSS) color information provided in beacon reports. As such, the AP may either enable or disable SR for communication based on determination whether the neighboring AP is part of the same enterprise.
