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.

Abstract: In one set of embodiments, one or more client stations operate to configure Neighbor Awareness Networking (NAN)—direct communication with neighboring client stations, i.e., direct communication between the client stations without utilizing an intermediate access point. Embodiments of the disclosure relate to NAN datapath scheduling and NAN pre-datapath operation setup and scheduling. The NAN datapath embodiments described herein provide a mechanism through which devices can communicate and provide services. Aspects of the datapath development include datapath scheduling, including datapath setup and scheduling attributes, as well as pre-datapath operation triggering and scheduling. Scheduling may include determination of a type of datapath, including paging and synchronized datapaths. NAN data cluster base schedules may be scheduled as equal-sets or subsets of datapath schedules. The datapath model may be implemented for unicast and multicast communication between client stations.

Abstract: Embodiments described herein relate to providing reduced power consumption in wireless communication systems, such as 802.11 WLAN systems. Timing information regarding power save opportunities (PSOPs) may be provided in communication frames, which may inform mobile devices of expected frame exchange periods during which they may transition to a Doze state. Additional PSOP information may be included in beacon frames, which may inform mobile devices of expected multicast periods during which they may transition to a Doze state. This may operate to provide improvements in terms of power consumption.

Abstract: In some embodiments, one or more wireless stations operate according to Neighbor Awareness Networking (NAN)—direct communication with neighboring wireless stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate to triggering a NAN datapath using Bluetooth low energy (BLE) signaling. The NAN datapath embodiments described herein provide a mechanism through which devices can communicate to establish a Wi-Fi connection via non-Wi-Fi signaling and provide services. Aspects of the datapath development include Wi-Fi connection establishment and datapath initiation. The datapath model may be implemented for unicast and/or multicast communication between wireless stations, including mobile stations.

Abstract: The disclosed embodiments provide a system that provides wireless service groups. During operation, a wireless device's advertising mechanism advertises a service group over Wi-Fi, wherein the service group comprises at least the wireless device and wherein the service group's security requirements regulate multicast protection within the service group. In response to receiving a request from a second device to be admitted into the service group, the wireless device's security mechanism admits the second device into the service group and sends the service group's security requirements to the second device, thereby enabling the second device to initialize multicast protection in accordance with the service group's security requirements.

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 accelerated service discovery between peer devices. In some embodiments, a wireless device may broadcast a probe beacon on one or more discovery channels. The wireless device may then scan the discovery channels for an extended period of time. The wireless device may receive a response from a peer device and transmit further service information to the peer device in an availability window indicated in the response.

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 and apparatuses are disclosed for high-bandwidth stations in a WiFi environment. In embodiments, a bandwidth of communications supported by the access point is divided into multiple frequency segments. In an embodiment, bandwidths up to 320 MHz are supported, which can be subdivided into four frequency segments of 80 MHz each. Different stations park on different frequency segments, whereas the access point has its primary channel located on the first frequency segment. With this configuration, uplink and downlink channel access can be provided to the different stations using a primary channel hopping pattern, which is provided to the stations from the AP. This pattern provides time windows for each frequency segment, during which the stations in that segment are able to freely communicate. Several other aspects of the disclosure further support this configuration and other high-bandwidth configurations.

Abstract: Methods, systems and apparatuses for performing enhanced integrity protection techniques by an access point (AP) and non-AP are described. A station (STA) can receive, from an access point (AP), an integrity protection (IP) capability request and transmit an IP capability response to the AP. The STA can receive, from the AP, one or more downlink (DL) frames comprising at least one adjusted parameter field of a plurality of parameter fields. The STA can verify, based on at least one value of the adjusted parameter field or one or more parameter fields of the plurality of parameter fields, that the one or more DL frames have been correctly received from the AP.

Abstract: Embodiments herein provide systems, apparatuses, and methods for authentication of an access point and a station in a wireless local area network. An access point and station may generate a Key Encryption Key (KEK). The access point and station may send authentication credentials encrypted based on the KEK. The access point may authenticate the station by validating the station authentication credential, and the station may authenticate the access point by validating the access point authentication credential.
