Abstract: Certain aspects of the present disclosure provide a method for wireless communications at a first wireless device. The method generally includes generating a protected frame that indicates: 1) an updated starting sequence number (SSN) of a block acknowledgment (BA) window and 2) an intended purpose of the protected frame as a request to update a BA window with the updated SSN; outputting, for transmission to a second wireless device that the first wireless device has established a protected block acknowledgment (BA) agreement with, the protected frame; generating multiple medium access control (MAC) Protocol Data Units (MPDUs) with SNs within the updated BA window; and outputting, for transmission to the second wireless device, the multiple MPDUs.

Abstract: This disclosure provides methods, components, devices and systems that may help various wireless devices that select multiple primary channels, for a basic service set (BSS), to contend for channel access. An example method, performed at a first wireless node (e.g., an access point), generally includes obtaining, via a first primary channel, a frame indicating a first configuration of a first basic service set (BSS), and communicating, with at least a second wireless node in a second BSS, in accordance with a second configuration, said second configuration being based on the first configuration and one or more rules, wherein the second configuration configures a first operating bandwidth for the first primary channel and at least a second operating bandwidth for at least one second primary channel.

Abstract: This disclosure provides methods, components, devices and systems for preemption techniques for low latency devices. Some aspects more specifically relate to preemption techniques to enable transmission of low latency data. In some examples, an access point (AP) may transmit a first physical layer protocol data unit (PPDU) using a dedicated resource unit (RU) and a broadcast RU. The broadcast RU may indicate information for a preemption indication, such as a resource unit within the same transmission opportunity (TXOP) for the preemption indication. A wireless station (STA) with pending low latency data may transmit the preemption indication via the RU indicated by the first PPDU. The preemption indication may indicate that a subsequent scheduled PPDU in the TXOP will be preempted for the STA to transmit a PPDU and convey the low latency data.

Abstract: This disclosure provides methods, components, devices and systems for enabling coordinated multiple access on multiple primary channels. Some aspects more specifically relate to inter access point (AP) coordination to share a portion of a transmission opportunity (TXOP). A first AP may transmit a first signal on a secondary primary channel conveying an indication that a portion of the TXOP is available for sharing. The second AP may respond with a confirmation on the secondary primary channel that the second AP is tuned to the secondary primary channel. Accordingly, the second AP may transmit a second signal on the secondary primary channel to the first AP indicating that the portion of the TXOP is available for use. The second AP may use the portion of the TXOP to communicate with one or more station(s) on the secondary primary channel.

Abstract: This disclosure provides methods, components, devices, and systems for signaling for dynamic subchannel operation (DSO). Some aspects more specifically relate to indicating a set of subchannels supported for DSO. In some implementations, a wireless station (STA) may transmit a frame indicating subchannels supported for DSO (for example, for a specific link). An access point (AP) may receive the frame and may assign, using a control frame, one or more frequency resources of a subchannel of the set of subchannels to the STA for DSO. The STA may dynamically switch to the subchannel and may communicate via the subchannel while operating in a DSO mode. In some implementations, the STA may transmit capabilities information indicating that the STA supports the DSO mode. Additionally, or alternatively, the STA may dynamically enable or disable the DSO mode using action frames or aggregated-control (A-Control) subfields. The AP may support similar signaling.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for managing uplink access in a wireless local area network. A station (STA) may inform an access point (AP) of uplink quality of service (QOS) parameters for a traffic flow from the STA. The AP may control uplink resources to satisfy the QoS parameters. For example, the AP may select from among different access modes (including a single user (SU) access mode, an uplink multi-user (UL-MU) scheduled access mode, a multi-user enhanced distributed controlled access (MU EDCA) access mode, or a low latency (LL) access mode). The AP may cause the STA to use a SU access mode or the LL access mode if the UL-MU scheduled access mode and the MU EDCA access mode are not sufficient to satisfy the uplink QoS parameters for the traffic flow.

Abstract: In some implementations, an access point (AP) establishes a restricted target wake time (TWT) session including at least one restricted TWT service period (SP) for peer-to-peer (P2P) communications. The AP admits a group of wireless stations (STAs) associated with P2P communications as members of the restricted TWT session, obtains a transmission opportunity (TXOP) on the wireless channel during the at least one restricted TWT SP, and transmits, on the wireless channel, a protection frame identifying one or more STAs of the group of STAs belonging to the restricted TWT session that are permitted to transmit or receive P2P communications on the wireless channel during the TXOP. The protection frame may also indicate to receiving devices other than the one or more identified STAs that the wireless channel is unavailable for at least a portion of the TXOP.

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: Aspects of the present disclosure generally relate to wireless communications and, more particularly, to techniques for managing multi-link communications. Some aspects of the present disclosure provide techniques for configuring data unit and control response transmissions on multiple links. The data unit and control responses may be configured such that a control response transmission does not overlap with a data unit reception at a station that is without simultaneous transmission and reception capability.

Abstract: In some implementations, a first access point (AP) selects one or more other APs for participation with the first AP in a coordinated access point transmission session. The first AP obtains a transmission opportunity (TXOP), and transmits a frame indicating scheduling information for uplink (UL) or downlink (DL) transmissions to or from the selected APs, the scheduling information indicating a respective start time for the UL or DL transmissions to or from the selected APs, at least two of the start times being offset from one another by a time period associated with decoding a preamble of a wireless packet. The first AP transmits or receives wireless packets to or from one or more associated stations (STAs) at least partially concurrently with the transmission or reception of wireless packets by the selected APs to or from their respective associated STAs based on the scheduling information.
