Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing a target wake time (TWT) scheme that includes traffic differentiation and service period extension. For example some embodiments relate to an electronic device including a transceiver and one or more processors communicatively coupled to the transceiver. The one or more processors receive an indication of traffic associated with an application. The one or more processors determine information associated with the traffic and configure the TWT scheme associated with the traffic based at least in part on the determined information. The one or more processors further communicate initial information associated with the TWT scheme to an access point of a wireless network. The initial information associated with the TWT scheme can include at least one of traffic direction information, traffic pattern information, a traffic identifier (TID), or an access category, indication (ACID).

Abstract: Some embodiments include an apparatus and method for enabling concurrent peer-to-peer (P2P) communications via a scheduled resource unit (RU) allocated by an access point (AP). For example, the AP may use a trigger frame to schedule uplink (UL) multi-user (MU) access for a first station of a plurality of stations by allocating an RU to the first station. Instead of using the allocated RU for UL infrastructure communications with the AP, the first station may utilize the allocated RU for a P2P communications with a second station. In some embodiments the AP facilitates RU utilization for P2P communications between stations. In some embodiments, the first station uses the allocated RU and the AP may be unaware of the P2P communications.

Abstract: An electronic device may transmit beacons associated with multiple access points that are cohosted by the electronic device, and that provide concurrent links in different bands of frequencies. The electronic device may include an access-point multi-link device (AP MLD). Moreover, the beacons may include: a basic service set identifier (BSSID) associated with the access points in the AP MLD, a service set identifier (SSID) associated with the access points in the AP MLD, and a MLD media access control (MAC) address associated with the access points in the AP MLD. Furthermore, a given beacon may be associated with a given access point and may include: information specifying a channel of a given link, a reduced neighbor report (RNR) providing information about at least the access points in the AP MLD, and a field that indicates when the given access point is included in the AP MLD.

Abstract: Embodiments are disclosed for group cast with retries (GCR) in a multi-link wireless communications system. In some embodiments, an access point (AP) multi-link device (MLD) can exchange information with a non-AP MLD to establish a GCR-multi-link operation (MLO) agreement corresponding to a group address, wherein the information includes, but is not limited to: a GCR primary link or a GCR primary link set of the AP MLD, an association identifier (AID) that corresponds to the group address. In some embodiments, the AP MLD can transmit a GCR frame subject to the GCR-MLO agreement, where the GCR frame includes a sequence number assigned from sequence number space (SNS)_GCR_MLO defined at a MLD level, and generate a Group Temporal Key (GTK)_GCR_ML at the MLD level, where the GTK_GCR_ML enables encryption and decryption of the GCR frame.

Abstract: An electronic device that performs a scan is described. During operation, the electronic device may perform, using a scanning radio, the scan of a band of frequencies, where the scanning radio only receives frames. Then, the electronic device may receive, using the scanning radio, a beacon associated with a second electronic device, where the beacon includes information associated with operation of a third electronic device in a second band of frequencies. Next, the electronic device may perform, using a data radio, a second scan of the second band of frequencies based at least in part on the information, where the data radio transmits and/or receives second frames, and where the second scan is performed, at least in part, while the scan is performed. Note that the electronic device may not be associated with (or may not have a connection with) the second electronic device and/or the third electronic device.

Abstract: Techniques for trigger-based transmission in a wireless network include receiving, at a first wireless device, a trigger signal including an indication of a first value for a parameter of a trigger-based physical layer protocol data unit (TB PPDU) transmission to a second wireless device, selecting, by the first wireless device, a second value for the parameter of the TB PPDU transmission, wherein the second value for the parameter is different from the first value for the parameter, and transmitting, by the first wireless device and to the second wireless device, the TB PPDU transmission using the second value for the parameter.

Abstract: An electronic device may receive a frame associated with a second electronic device. This frame may include a MAC header with information specifying a request for a trigger or a trigger frame, and the information may include a suggested time interval during which the trigger or the trigger frame is to be provided and a requested resource allocation. For example, the MAC header may include an A-control field, and the A-control field may include the information or may include multiple A-MPDUs and one or more of the A-MPDUs (such as a last A-MPDU or all of the A-MPDUs) may include the information. Moreover, the time interval may begin at a previous transmission associated with the second electronic device, and the requested resource allocation may include a capacity. In response to the request, the electronic device may provide the trigger or the trigger frame addressed to the second electronic device.

Abstract: A dual-radio AP including both a high-power (e.g., Wi-Fi) radio and a low-power (e.g., BLE) radio may support an assisted wakeup service for a power-limited dual-radio mobile device (STA). The power-limited STA may register with the AP for the assisted wakeup service, and may then disable its Wi-Fi radio (or otherwise initiate a lower-power mode). The power-limited STA may receive a BLE communication indicating the AP has pending Wi-Fi transmissions or updates applicable to the power-limited STA. In response, the power-limited STA may turn on its Wi-Fi radio and receive the pending transmissions or updates from the AP. If an AP does not include a low-power radio, then a high-power/low-power dual-radio STA that is not power-limited may serve as an assisted wakeup service proxy. The proxy may scan and trace the Wi-Fi beacons from the AP, and generate the BLE communication to the power-limited STA on behalf of the AP.

Abstract: An interface circuit in an electronic device (such as an access point) may receive a wake-up-radio (WUR)-setup request associated with a recipient electronic device, where the WUR-setup request specifies one or more proposed data criteria or wake-up criteria that indicate when a wake-up frame is to be transmitted to the recipient electronic device. In response, the electronic device may determine one or more data criteria (or wake-up criteria) for use based at least in part on the one or more proposed data criteria. Then, the interface circuit may provide a WUR-setup response intended for the recipient electronic device, where the WUR-setup response indicates acceptance of the one or more proposed data criteria for use as the one or more data criteria or a proposed modification of at least one of the one or more proposed data criteria.
