Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing discovery frames and group addressed frames communication. For example, some embodiments relate to a method including generating a first frame to be transmitted to a first electronic device. An association identifier (AID) value of the first frame is set to a first value to indicate that the first frame is an individually addressed frame addressed to the first electronic device. The method further includes generating a second frame to be transmitted to a group of one or more electronic devices. An AID value of the second frame is set to a second value different from the first value. The method also includes transmitting the first frame and the second frame.

Abstract: This disclosure relates to transmitting multicast information over a network, such as a wireless local area network (WLAN). A source device may transmit a multicast and a request for feedback to a plurality of sink devices. The sink devices may transmit feedback based on whether they successfully decoded the multicast. The source device may retransmit the multicast (or a portion thereof) based on the feedback.

Abstract: 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. A wireless station may enter an unsynchronized discovery mode, transmit, in response to receiving a subscribe message from a neighboring device, a publish message to the neighboring device, perform authentication and trusted device cluster provisioning with the neighboring wireless device, and protect transmissions using the security credentials. In the unsynchronized discovery mode, the wireless device may monitor a discovery channel for subscribe messages, e.g., from neighboring peer devices. Additionally, the trusted device cluster provisioning may provide security credentials to the wireless device. Note that protecting transmissions using the security credentials may include protecting a trusted device cluster identity, transmitted beacons, transmitted management frames, or transmitted action frames using the security credentials acquired via the trusted device cluster provisioning.

Abstract: Methods for performing robust discovery of a new access point (AP) in AP MLD, robust link addition to an AP MLD association, AP beaconing modes when the AP is added or deleted to/from an AP MLD, and robust BSS transition management (BTM) signaling to steer a non-AP MLD to a best AP MLD and to most suitable APs, as well as privacy improvements for associated non-AP MLD.

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: This disclosure relates to service discovery using a dynamically configurable Bloom filter. According to some embodiments, various parameters of the Bloom filter may be determined by a first wireless device. The parameters may include a number of services advertised using the Bloom filter, a false positive rate of the Bloom filter, a set of hash functions used with the Bloom filter, and/or a size of the Bloom filter. The Bloom filter may be generated according to the determined parameters. The Bloom filter, along with some or all of the parameters of the Bloom filter, may be transmitted by the first wireless device. A second wireless device may use the Bloom filter as part of a service discovery process to determine whether or not a desired service is available via the first wireless device.

Abstract: 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. A wireless station may determine a further availability window schedule for a first time period, including specifying availability for particular channels at particular time slots at a first time slot increment. The wireless station may specify availability at a second time slot increment for a subset of the time slots specified at the first time slot increment. The second time slot increment may be less than the first slot time increment. The wireless station may negotiate, with a neighboring wireless station, a peer-to-peer communication schedule for the peer-to-peer communication application based on the further availability window schedule, including specifying a portion of the peer-to-peer schedule using the second time slot increment.

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: 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 mitigate medium congestion in discovery windows may include suppressing solicited publisher responses via an SRF for a first time period and resetting the SRF after the first time period in order to receive updates from peer devices.

Abstract: 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. A wireless station may be configured to perform a method to accelerate discovery of a peer device after an out-of-band triggering event. For example, a wireless device may detect an out-of-band triggering event and activate a wireless interface capable of peer-to-peer communications in response. The wireless device may transmit one or more discovery messages (e.g., discovery beacons, active subscribe messages, and/or unsolicited publish messages) over the wireless interface immediately after activation of the wireless interface to aid in discovery of the peer device. The one or more discovery messages may be transmitted as service discovery frames. The wireless device may perform service discovery over the wireless interface with the peer device post discovery.
