    Abstract: An electronic device (such as an access point) that receives one or more block acknowledgments is described. This electronic device may transmit an extremely high-throughput (EHT) physical layer convergence protocol (PLCP) protocol data unit (PPDU) to a recipient electronic device, where the EHT PPDU is transmitted in multiple non-contiguous sub-bands that are separated by a punctured sub-band. Moreover, the electronic may receive the one or more block acknowledgments from the recipient electronic device, where the one or more block acknowledgments exclude the punctured sub-band. Note that the EHT PPDU may exclude transmitted energy in the punctured sub-band. Moreover, the punctured sub-band may have a bandwidth of at least 20 MHz and may be different from a primary sub-band.

    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: 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.

    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.
