Abstract: Embodiments are disclosed for triggered multi-link (ML) access coordination. A station (STA) ML device (MLD) can establish a preferred triggering link (PTL) with an access point (AP) MLD where the PTL is the preferred link for receiving triggering frames. The STA MLD can transmit uplink (UL) frames via the PTL in response to a trigger frame. Subsequently, the STA MLD can determine that the PTL is busy, and transmit enhanced distributed channel access (EDCA) UL frames on a non-PTL link. In a power save mode, the STA MLD can use the PTL to exchange UL and downlink (DL) frames. Multiple PTLs can be established supporting concurrent trigger frames, and different ranges of traffic IDs (TIDs) can be used for each PTL. The STA MLD can utilize AP MLD link pair information to receive a DL retransmission corresponding to one TID via both links of the AP MLD link pair.

Abstract: Some embodiments include an apparatus, method, and computer program product for dynamic window access point (AP) power save enhancements. Some embodiments include transmitting an availability window (AW) of an AP to stations (STAs) and dynamically modifying the AW. In some embodiments, a mobile device may perform soft AP functions and associate with the stations. The modifications can include truncating or extending the AW. Some embodiments include: a broadcast availability frame that informs STAs of the modified AW; an Availability Clear To Send (A-CTS) frame that allows the AP to inform associated STAs of the modified AW; and/or an uplink (UL) multi-user (MU)-Request to Send (RTS) Enabled feature, that allows an AP to be available while operating in a low power receive (LPR) state (e.g., low power mode) and transition to a full power state to receive data using a bandwidth greater than 20 MHz.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing a hibernation mode for multi-link wireless communication networks such as a wireless local area network (WLAN). For example, some aspects relate to a multi-link device (MLD) including a first station (STA) associated with a first link of a wireless network and configured to communicate with a second MLD over the first link. The MLD also includes a second STA associated with a second link of the wireless network. The second STA is in a hibernation mode. The MLD also includes one or more processors communicatively coupled to the first and second STAs and configured to control operations of the first and second STAs.

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: 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: Methods and apparatuses are disclosed for high-bandwidth stations in a WiFi environment. In embodiments, a bandwidth of communications supported by the access point is divided into multiple frequency segments. In an embodiment, bandwidths up to 320 MHz are supported, which can be subdivided into four frequency segments of 80 MHz each. Different stations park on different frequency segments, whereas the access point has its primary channel located on the first frequency segment. With this configuration, uplink and downlink channel access can be provided to the different stations using a primary channel hopping pattern, which is provided to the stations from the AP. This pattern provides time windows for each frequency segment, during which the stations in that segment are able to freely communicate. Several other aspects of the disclosure further support this configuration and other high-bandwidth configurations.

Abstract: Some embodiments include an apparatus, method, and computer program product for infrastructure and peer-to-peer (P2P) medium access sharing. Some embodiments enable an access point (AP) to assist associated stations (STAs) in accessing a channel. In some embodiments, an AP can receive a request for coordinated transmission for peer-to-peer (P2P) communications, determine a bandwidth available for use during a transmit opportunity (TXOP), and allocate, from the bandwidth, a first subset of one or more channels for infrastructure communications and a second subset of one or more channels for the P2P communications responsive to the request. The AP can transmit to a STA, a first signal corresponding to the second subset of one or more channels for the P2P communications, indicating that the second subset of one or more channels can be used for P2P communications during the TXOP.
