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 transmitting multicast information over a network, such as a wireless local area network (WLAN). A source device may transmit a multicast and a request for feedback to a plurality of sink devices. The sink devices may transmit feedback based on whether they successfully decoded the multicast. The source device may retransmit the multicast (or a portion thereof) based on the feedback.

Abstract: Methods, systems and apparatuses for performing a channel switch by an access point (AP) multi-link device (MLD) and non-AP MLD are described. An AP MLD may transmit information about parameters of an AP that will be implemented following an upcoming channel switch. The non-AP MLD may use the information to implement the channel switch.

Abstract: During operation, an electronic device may perform, using a scanning radio, a scan of a band of frequencies, where the scanning radio only receives frames. Then, the electronic device may receive, using the scanning radio, a beacon frame associated with a second electronic device, where the beacon frame includes information associated with operation of a third electronic device in a second band of frequencies. Next, the electronic device may perform, using a data radio, a second scan of the second band of frequencies based at least in part on the information, where the data radio transmits and/or receives second frames, and where the second scan is performed, at least in part, while the scan is performed. Note that the electronic device may not be associated with (or may not have a connection with) the second electronic device and/or the third electronic device.

Abstract: An electronic device is described. This electronic device may associate with a second electronic device (such as an access point) in a WLAN. While associating or associated with the second electronic device, the electronic device may receive, from the second electronic device, an AID corresponding to the electronic device for use when communicating frames in the WLAN. Moreover, while associated with the second electronic device, the electronic device may obtain a second AID corresponding to the electronic device for use when communicating second frames in the WLAN, where the associating includes replacing the AID with the second AID. Note that obtaining the second AID may include: the electronic device selecting the second AID from a predefined set of AIDs, which were previously received from the second electronic device; or the electronic device receiving, from the second electronic device, the second AID.

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: During operation, an electronic device (e.g., an access point) may provide a multi-user (MU)-request-to-send (RTS) frame that communicates an RTS in a channel associated with the second electronic device and a second RTS in a second channel associated with a third electronic device. For example, the channel may include a primary channel and the second channel may include a secondary channel. Note that the third electronic device may include a SST station and the second electronic device may include a non-SST station. Then, the electronic device may receive an MU-clear-to-send (CTS) frame that includes a CTS in a third channel associated with the third electronic device. Moreover, the third channel may be equal to or a subset of the second channel, and/or the third channel may include a CTS reception channel associated with the electronic device.

Abstract: This disclosure relates to methods for providing unsolicited unavailability announcements to manage the co-existence of Wi-Fi and other technologies (such as Bluetooth) and to manage infrastructure and peer-to-peer connections in a wireless communication system. A wireless device may establish multiple wireless connections on a set of radio resources. The wireless device may transmit an unsolicited unavailability announcement frame, which may include information indicating a time period of future unavailability for the wireless device on the set of radio resources. Such an unsolicited unavailability announcement frame may also include information regarding the device's current availability, for example during which the device plans to initiate a transmit opportunity.

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.
