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.

Abstract: Embodiments may relate to group addressed frame delivery over multi-link systems. Systems and methods are configured for identifying, by an access point (AP) multilink device (MLD) in a wireless network, a first sequence number space (SNS) that is to be used by the AP MLD to transmit data to a non-AP MLD over a first communications link and a second communications link, wherein frames with identical data that are transmitted over the first and second communications links will have an identical first SN based on the first SNS; identifying, by the MLD in the wireless network, the first SN based on the first SNS; and transmitting, by the AP MLD in the wireless network, a frame that includes the data to the non-AP MLD based on the first SN.

Abstract: A multilink access point may communicate with a legacy device. The multilink access point identifies an attempt, by at least one legacy station, to connect to the access point, determines that the at least one legacy station does not support multilink communications, broadcasts a beacon identifying information for a basic communication link that can be used by the at least one legacy station and associates with the at least one legacy station based at least on information included in the beacon, wherein the at least one legacy station communicates exclusively on the basic communication link with the access point.

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: Some embodiments of this disclosure include apparatuses and methods for a media access control (MAC) level operation that enables a transmitter and a receiver to select low-density parity check (LDPC) codewords that are HARQ retransmitted. The operations described herein provide for reducing the number of codewords that need to be retransmitted, minimizing the overhead needed to signal the feedback from a receiver to a transmitter, and allowing a transmitter to control which codewords are retransmitted.

Abstract: A mobile device may receive a plurality of polling messages with each polling message including an identifier of a particular access device transmitting the polling message. Each polling message of the plurality of polling messages may be transmitted during a polling phase. The mobile device may select a timeslot of a response phase of a communication session. The mobile device may transmit a response message during the timeslot of the response phase. The mobile device may receive, during a third phase, an assignment message including an assigned timeslot for a response phase of a future session. The mobile device may perform secure ranging with one or more access devices of the plurality of access devices during the future session using the assigned timeslot. The mobile device may provide an access credential to the one or more access devices based on a location determined using the secure ranging.

Abstract: An electronic device (such as an access point) is described. This electronic device transmits an orthogonal frequency division multiple access (OFDMA) frame to a recipient electronic device (such as a client or a station). The OFDMA frame includes multiple predefined resource units (RUs) allocated to the recipient electronic device in a set of predefined RUs having associated frequency bandwidths. Moreover, the multiple predefined RUs include two or more first predefined RUs having a first number of tones less than a predefined amount, or two or more second predefined RUs having a second number of tones greater than or equal to the predefined amount. For example, the predefined amount may include 242 tones. Note that the multiple predefined RUs may have the same or different numbers of tones. Moreover, the electronic may receive an acknowledgment or a block acknowledgment from the recipient electronic device.

Abstract: An electronic device (such as an access point) that performs a remedial action is described. This electronic device may transmit, using a first radio in the electronic device, a physical layer convergence protocol (PLCP) protocol data unit (PPDU) to a recipient electronic device on a first link between the electronic device and the recipient electronic device, where the PPDU includes a PPDU preamble and a set of media access control (MAC) protocol data units (MPDUs). Then, the electronic device may receive, using a second radio in the electronic device, feedback from the recipient electronic device on a second link between the electronic device and the recipient electronic device. Next, the electronic device may perform the remedial action based at least in part on the feedback. For example, the electronic device may abort the PPDU transmission and/or retransmit one or more of the set of MPDUs.
