Abstract: In some embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate to a mechanism for peer NAN devices to assist one another in receiving communications from an access point common to the peer NAN devices. In some embodiments, a wireless station may establish a communication link with a Wi-Fi access point and establish a peer-to-peer communication link with one or more neighboring wireless stations. In addition, the wireless station may receive transmissions intended for at least one neighboring wireless station of the one or more neighboring wireless stations from the Wi-Fi access point and relay the transmissions to the at least one wireless station on behalf of the Wi-Fi access point.

Abstract: Methods, systems, and apparatus are presented for providing enhanced scheduling requests, e.g., in an IEEE 802.11 network. A client station (STA) may determine one or more minimum quality of service (QoS) metrics for supporting an application being implemented by the STA, and may determine minimum scheduling parameters to be implemented by an access point (AP) to achieve the minimum QoS. The STA may transmit to the AP a specific scheduling request indicating the minimum scheduling parameters. In response, the AP may schedule communication resources for the STA in accordance with the minimum scheduling resources.

Abstract: An interface circuit in an electronic device (such as an access point) may receive a setup request associated with the recipient electronic device. The setup request may specify a group address for which the recipient electronic device wants to receive associated frames and a proposed transmission interval. Based at least in part on the proposed transmission interval, the electronic device may determine a transmission schedule and/or may assign, based at least in part on the group address, the recipient electronic device to an aggregated group having a flexible multicast service identifier (FMSID). Then, the electronic device may provide a wake-up frame for the recipient electronic device, where the wake-up frame includes an identifier of the aggregated group for which a group-addressed frame will subsequently be transmitted by the electronic device. Moreover, the wake-up frame may be provided at a transmission time based at least in part on the transmission schedule.

Abstract: One or more wireless stations may operate to configure Neighbor Awareness Networking (NAN)—direct communication with neighboring wireless stations, e.g., without utilizing an intermediate access point. Scheduling of NAN ranging procedures may include a first wireless station sending first information, including first scheduling preferences and a first ranging role, to a second wireless station. The first wireless station receives second information, including second scheduling preferences and a second ranging role, from the second wireless station. The first wireless station may initiate the ranging procedure based on the scheduling preferences and ranging parameters. Alternatively, the second wireless station and may initiate the ranging procedure based on the scheduling preferences and ranging parameters.

Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing a queuing latency aware buffer status report (BSR). 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 determine an amount of data queued in a buffer for transmission over the wireless network and determine latency information associated with the queued data. The one or more processors generate a queuing latency aware buffer status report (BSR) based at least on the determined latency information. The electronic device transmits the queuing latency aware BSR to an access point.

Abstract: An electronic device (such as an access point) may provide a management frame, intended for at least a recipient electronic device, that includes slotted-operation information corresponding to a power-save mode of the electronic device for communication with at least the recipient electronic device. The slotted-operation information may include a sequence of temporal slots and associated channel information for the temporal slots. When a channel for a temporal slot comprises a null value, the power-save mode may include transitioning the electronic device into a lower-power-consumption mode during the temporal slot. Alternatively, when a channel for a temporal slot is different than a null value, the power-save mode may include performing another activity than communicating with the recipient electronic device during the temporal slot.

Abstract: An interface circuit in an electronic device (such as an access point) may request a channel status in order to specify a subset of one or more frequency sub-bands. During operation, the interface circuit may provide at least a frame to the recipient electronic device, where the frame requests the channel status for the one or more frequency sub-bands. Then, the electronic device may receive one or more measurement results from the recipient electronic device that specify the subset of the one or more frequency sub-bands (such as one or more RUs) that are not to be used when communicating with the recipient electronic device.

Abstract: An interface circuit in an electronic device (such as an access point) may provide a wake-up beacon to a recipient electronic device. During operation, the interface circuit may provide a wake-up beacon associated with a predefined sub-channel in one or more channels in a band of frequencies, where the wake-up beacon is for a wake-up radio in the recipient electronic device. Moreover, the wake-up beacon may be provided within an associated time interval, such as a keep-alive interval of the electronic device. In some embodiments, the wake-up beacon includes a field with channel information that specifies one or more second channels used by a main radio in the recipient electronic device. Alternatively or additionally, the wake-up beacon may include a field with service information that specifies one or more types of services and/or a field with information specifying a transmit power of the interface circuit.

Abstract: This disclosure relates to methods for conducting multilink communications between a user equipment device (UE) and a wireless access point (AP) over a wireless local area network (WLAN). The UE establishes a connection with an access point through a WLAN, wherein the connection utilizes a plurality of links. The UE transmits an indication to the access point through a first link of the plurality of links, where the indication specifies one or more available links of the plurality of links that are available for the UE to receive downlink (DL) communications from the access point. The UE receives one or more DL communications from the access point through at least one of the one or more available links.

Abstract: An electronic device that selectively provides a trigger frame is described. During operation, the electronic device may receive a frame from a recipient electronic device, where the frame includes information that specifies a maximum uplink multi-user transmit duration of the recipient electronic device. Moreover, the electronic device may selectively provide the trigger frame to the recipient electronic device that specifies an uplink OFDMA frame or an uplink MIMO frame associated with the recipient electronic device. The trigger frame may be selectively provided when a transmit time corresponding to the uplink OFDMA frame or the uplink MIMO frame is less than or equal to the maximum uplink multi-user transmit duration.
