Abstract: Some embodiments include an apparatus, method, and computer program product for access point (AP)-assisted AP transition. Using AP-assisted AP transitions, when the STA is associated with a first access point (AP) and is transitioning to a second AP, a station (STA) can transmit to the second AP a control signal including a first indication for sequence number (SN) maintenance. The STA can receive from the second AP responsive to the first indication for SN maintenance, a first downlink (DL) transmission including a next SN. The next SN can be a continuation of an SN sequence utilized by the first AP for one or more previous DL transmissions.

Abstract: A wireless device may transmit ranging transmissions using a compressed PSDU. The compressed PSDU may be configured to support poll packets, response packets, and report packets. The compressed PSDU may comprise an identifier (ID) field, an address field, ID specific data, and a cyclic redundancy check (CRC) field. Further, the wireless device may use an optimized header IE for broadcast.

Abstract: Methods, systems and apparatuses for managing roaming by access points (AP), a controller, and a wireless device are described. The wireless device may indicate intent to roam from a source AP to a target AP. The wireless device, APs, and controller may adjust buffering in anticipation of the change. The wireless device, APs, and controller may deliver buffered data via the target AP following a successful change from the source AP.

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: 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: 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.
