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, systems and apparatuses for performing a channel switch by an access point (AP) multi-link device (MLD) and non-AP MLD are described. An AP MLD may transmit information about parameters of an AP that will be implemented following an upcoming channel switch. The non-AP MLD may use the information to implement the channel switch.

Abstract: A wireless communication system may include a Multi-link Multi-device (MLMD). The MLMD may be associated with a single MLMD MAC address. A set of access point (AP) multi-link devices (MLDs) may be associated with the MLMD. Each of the AP MLDs may comprise one or more APs. A station (STA) may use the MLMD MAC address to setup links with multiple APs across different AP MLDs and roam between the APs.

Abstract: A method for communicating over a wireless network includes broadcasting, by a Multi-Link Device (MLD) device, service data indicative of one or more services for wireless communication with a client device; wherein the service data indicates that a service type is differentiated based on a type of the client device; establishing a security association with the client device; and in response to establishing a security association with the client device, granting access by the client device to a subset of the one or more services based on the type of the client device.

Abstract: A wireless device may use 2.5 MHz narrow band channel spacing. In some embodiments, clear channel assessment based listen before talk may be used to determine if a channel is idle or busy. In some embodiments, randomized channel access may be achieved using a pseudo random number generator on an allowed list of channels. In some embodiments, an avoid loitering mechanism may be employed to reduce interference with transmitters using the same frequency bands.

Abstract: During operation, an electronic device may perform, using a scanning radio, a 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 frame associated with a second electronic device, where the beacon frame 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: An electronic device is described. This electronic device may associate with a second electronic device (such as an access point) in a WLAN. While associating or associated with the second electronic device, the electronic device may receive, from the second electronic device, an AID corresponding to the electronic device for use when communicating frames in the WLAN. Moreover, while associated with the second electronic device, the electronic device may obtain a second AID corresponding to the electronic device for use when communicating second frames in the WLAN, where the associating includes replacing the AID with the second AID. Note that obtaining the second AID may include: the electronic device selecting the second AID from a predefined set of AIDs, which were previously received from the second electronic device; or the electronic device receiving, from the second electronic device, the second AID.

Abstract: This disclosure relates to methods for managing uplink transmit opportunity bursting for wireless local area networking. A wireless device may initiate a transmit opportunity to perform an uplink transmission to an access point. The wireless device may receive an acknowledgement from the access point. The acknowledgement may include an indication that the wireless device can initiate a second transmit opportunity without wireless medium contention. The wireless device may initiate the second transmit opportunity without wireless medium contention based at least in part on the indication received from the access point.
