Abstract: During operation, an electronic device may encrypt an A-control subfield. Then, the electronic device may provide the frame addressed to a second electronic device, where the frame includes a media access control (MAC) header and the MAC header includes the A-control subfield that is encrypted. Note that the encrypted A-control subfield may be jointly encrypted with data in a payload in the frame. Moreover, the encrypted A-control subfield may be separated from the payload in the frame by one or more additional subfields or may be adjacent to the payload in the frame. Furthermore, the MAC header may include an indicator that indicates whether the A-control subfield is encrypted. Additionally, the frame may include a preamble that indicates whether the A-control subfield is encrypted. The frame may be received by the second electronic device. After receiving the frame, the second electronic device may decrypt the A-control subfield.

Abstract: A second electronic device that receives a frame is described. This second electronic device includes: an antenna node communicatively coupled to an antenna; and a second interface circuit, communicatively coupled to the antenna node, that communicates with an electronic device. During operation the second interface circuit receives, associated with the electronic device, the frame that includes an indication that the electronic device uses a frame-based equipment (FBE) channel access technique and attributes of the FBE channel access technique. The attributes include: a duration of the FBE channel access technique, and a fixed frame period (FFP) for communication during the FBE channel access technique. Moreover, the frame is compatible with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard.

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: This disclosure relates to methods for managing uplink transmit opportunity bursting for wireless local area networking. A wireless device may initiate a transmit opportunity to perform an uplink transmission to an access point. The wireless device may receive an acknowledgement from the access point. The acknowledgement may include an indication that the wireless device can initiate a second transmit opportunity without wireless medium contention. The wireless device may initiate the second transmit opportunity without wireless medium contention based at least in part on the indication received from the access point.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing request to send (RTS) and clear to transmit (CTS) frames and transmission rules for the RTS and CTS frame. For example, some aspects relate to an electronic device including a transceiver and one or more processors communicatively coupled to the transceiver. The one or more processors receive, using the transceiver, a request to send (RTS) frame from the second electronic device and determine, using the received RTS frame, a format for a clear to send (CTS) frame to use in response to the RTS frame. The one or more processors further transmit, using the transceiver, the CTS frame based on the determined format on at least one sub-channel on which the RTS frame was received and that the at least one sub-channel is idle.
