Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing block acknowledgment (BA) operations for multi-link wireless communication networks. 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 transmit, using the transceiver and to a second electronic device, a first set of one or more frames on a first link and a second set of one or more frames on a second link. The one or more processors receive, using the transceiver and from the second electronic device, a first block acknowledgment (BA) frame on the first link and a second BA frame on the second link. The one or more processors further determine, based on received first BA frame and the second BA frame, a failed or missing frame of the first set of one or more frames transmitted on the first link.

Abstract: One or more wireless stations may operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. A mechanism for wireless stations to learn preferred channels of neighboring wireless stations and to schedule channel sequences within a time period based on the learned channels may include advertisement of preferred channels and adaptation of channel sequences, based on the preferred channels, to maximize bandwidth utilization.

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: During operation, an electronic device may encrypt an A-control subfield. Then, the electronic device may provide the frame addressed to a second electronic device, where the frame includes a media access control (MAC) header and the MAC header includes the A-control subfield that is encrypted. Note that the encrypted A-control subfield may be jointly encrypted with data in a payload in the frame. Moreover, the encrypted A-control subfield may be separated from the payload in the frame by one or more additional subfields or may be adjacent to the payload in the frame. Furthermore, the MAC header may include an indicator that indicates whether the A-control subfield is encrypted. Additionally, the frame may include a preamble that indicates whether the A-control subfield is encrypted. The frame may be received by the second electronic device. After receiving the frame, the second electronic device may decrypt the A-control subfield.

Abstract: Embodiments described herein relate to a system and method for providing flexible receiver configuration in wireless communication systems, such as 802.11 WLAN systems. In one embodiment, a wireless device may transmit a first data frame including first configuration information specifying a first configuration of the receiver to notify a remote device that the wireless device intends to configure its receiver according to the first configuration. After receiving an acknowledgement frame confirming the first configuration information, the wireless device may configure the receiver according to the first configuration. In another embodiment, a wireless device may receive a first data frame including first configuration information and further including a request that the wireless device configure its receiver according to the first configuration. In response, the wireless device may configure the receiver according to the first configuration. In either case, the wireless device may receive subsequent communications according to the first configuration.

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 electronic device that communicates frames is described. During operation, the electronic device may transmit the frames addressed to a recipient electronic device and associated with multiple links between the electronic device and the recipient electronic device. Then, the electronic device may receive block acknowledgments for at least a subset of the frames, where a given block acknowledgment is associated with the recipient electronic device and indicates received frames on a given link in the links. Moreover, the electronic device may control an amount of traffic conveyed on the links based at least in part on the block acknowledgments. Next, the electronic device may store a remainder of the frames based at least in part on the block acknowledgments, where the frames include the subset of the frames and the remainder of the frames. Note that the frames may have a common traffic identifier.

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.
