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: 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: 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 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: Methods, systems and apparatuses for coordinating service periods by an access point (AP) and a wireless device are described. Information related to coexistence or other reduced availability can be determined and exchanged. A schedule of service periods can be created and can be adjusted as needed.

Abstract: This disclosure relates to methods for handling uplink frames in access point assisted roaming in a wireless local area network. A wireless device may establish a wireless association with a first access point. The wireless device may perform signaling to transition from the first access point to a second access point. The signaling may include an uplink reorder buffer handling request.

Abstract: In order to eliminate the reliance of ultra-high bandwidth (UWB) standalone transceivers and narrow-band-assisted (NB-assisted) UWB transceivers on BLUETOOTH™ (BLE) usage, an NB radio may be used. The NB radio may be tightly coupled with the UWB radio, for example driven by the same time source, to enable leveraged use of ACP (Acquisition Packet) for discovery, session setup, and maintenance over UWB and/or NB-assisted UWB without the use of BLE. Rules for advertising ACP and scanning for ACP may be defined for two modes of operation. An ad-hoc discovery may be based on external acquisition triggers, while a managed discovery may be based on an ongoing discovery advertisement process. ACPs may thereby be transmitted over UWB and/or NB.

Abstract: This disclosure relates to methods for multi-access point association in a wireless local area network. Multiple access point wireless devices may establish a multi-access point system. Other access point wireless devices may subsequently join the multi-access point system. Non-access point wireless devices may form an association with the multi-access point system, which may include links with multiple different access point wireless devices in the multi-access point system.
