Abstract: A management frame is generated which comprises a per-station profile of an access point (AP) affiliated with a AP multilink device (MLD) having a non-transmitted basic service set identifier (BSSID) AP. The per-station profile is carried in two or more elements, each element comprising an element identifier, a length, and an information field which carries a respective fragment of the per-station profile and the two or more elements are not in a multiple BSSID element. The management frame is transmitted to a station, wherein a non-AP of the station associates with the AP MLD based on the management frame.

Abstract: The present disclosure includes systems and techniques relating to broadcast and multicast in a wireless communication system. In some implementations, an announcement frame indicating a broadcast or multicast service period to multiple second wireless devices is transmitted by a first wireless device. The announcement frame indicates (i) an end time of the broadcast or multicast service period and (ii) an order of a sequence of frames to be directed to the multiple second wireless devices. Each of the sequence of frames is transmitted at the first wireless device using a directional antenna pattern to a respective one of the multiple second wireless devices, according to the order of the sequence of frames indicated in the announcement frame. An acknowledgement frame in response to the each of the sequence of frames is received at the first wireless device from the respective one of the multiple second wireless devices.

Abstract: In an IEEE 802.11bc wireless system, aggregated data frames are communicated between first and second STA devices by configuring the first STA device to assemble and transmit an A-MPDU frame having multiple A-MPDU subframes characterized by a fixed MPDU start spacing parameter and a fixed maximal MPDU length parameter, where the first STA device is configured with the fixed MPDU start spacing parameter and the fixed maximal MPDU length parameter without negotiating association request and response messages, and by configuring the second STA device to assemble and transmit a BA message comprising a BA bitmap identifying the one or more of the multiple A-MPDU subframes which are not successfully received by the second STA device, where the BA bitmap has a size characterized by a fixed buffer size parameter which is configured at the second STA device without negotiating add BA request (ADDBA Request) request and response messages.

Abstract: Aspects of the present disclosure involve negotiating a TWT agreement by communicating which links, of a multi-link system as may be used in WiFi communications, are to be used for negotiating the TWT agreement. This communication may be accomplished, for example, by using fields of the MAC header, individual TWT parameter set, or broadcast TWT parameter set.

Abstract: A first communication device generates and transmits a first physical layer (PHY) data unit as part of a hybrid automatic repeat request (HARQ) session, the first PHY data unit having a first plurality of media access control (MAC) protocol data units (MPDUs) including a first MPDU. The first communication device determines that a second communication device did not acknowledge successfully receiving the first MPDU. The first communication device generates and transmits a second PHY data unit as part of the HARQ session, the second PHY data unit having a second plurality of MPDUs, the second plurality of MPDUs including the first MPDU.

Abstract: Aspects of the present disclosure are directed to wireless communications based on a restricted TWT SP and buffer status. As may be implemented in accordance with one or more embodiments, frames are transmitted based on a restricted TWT SP and buffer status for communications between a wireless circuits. Control data for the communications traffic may be processed in response to the restricted TWT SP, with a TXOP ending at the beginning of a restricted TWT SP of a another link, in response to the restricted TWT SP being negotiated in a different link. Such an approach may be carried out where one of the wireless circuits has no STR configuration. A protected duration time for the TWT SP may be set to a time that is less than a duration of the TWT SP in response to the TWT SP being protected by a quiet element duration period.

Abstract: A method for securing a Wi-Fi link in a wireless communication system includes configuring an existing agent with a controller, wherein the existing agent is configured as a first Basic Service Set (BSS). An enrollee agent is onboarded with a Push Button Configuration (PBC) method to establish an 1905 layer security between the existing agent and the enrollee agent. The enrollee agent is configured with the controller, including the controller transmitting a Device Provisioning Protocol (DPP) Bootstrapping Information Request to the enrollee agent and the controller receiving a DPP Bootstrapping Information Response from the enrollee agent, wherein the enrollee agent is configured as a second BSS.
