Abstract: Some embodiments include utilizing a multilink media access control (MAC) address structure to support multilink devices (MLDs) that can operate concurrently in more than one link such as extremely high throughput (EHT) access points (APs) and EHT stations (STA), where the multilink MAC address structure is compatible with legacy devices. An EHT AP can utilize a multilink basic service set (BSS) identification (BSSID) MAC address to communicate with an EHT STA identified by a multilink MAC address. Values of the multilink BSSID and the multilink MAC address of the EHT STA are independent of which of the multiple links are used in the communication. In addition, to utilizing a multilink BSSID, the EHT AP can also support unique link-specific MAC addresses to concurrently support legacy and MLD stations. The EHT STA can also utilize unique link-specific MAC addresses that can be different than the EHT AP's link-specific MAC addresses.

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 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 power consumption mitigation techniques for downlink transmission of a high priority payload in wireless communication networks. For example, an electronic device includes a transceiver and a processor. The processor is configured to receive, using the transceiver and from a second electronic device, a preamble associated with a first payload. The processor is further configured to determine, based at least on the preamble, that a second payload is to be received. The processor is further configured to receive, from the second electronic device, an overload marker symbol (OMS) and determine, based at least on the OMS, whether the second payload is to be received following the OMS. The processor is further configured to transition the transceiver to, or maintain the transceiver in, an awake state in response to determining that the second payload is to be received following the OMS.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing backup link establishment and operation for multi-link wireless communication networks such as a wireless local area network (WLAN). Some aspects relate to an electronic device including a transceiver configured to communicate over a wireless network and a processor communicatively coupled to the transceiver. The processor receives a message including information associated with a backup link from a second electronic device. The processor further receives data associated with data traffic from the second electronic device on a primary link of the wireless network. In response to a quality of the primary link being below a threshold, the processor receives a notification frame from the second electronic device on the backup link and receives additional data associated with the data traffic from the second electronic device on the backup link or on an other link informed by the notification frame.

Abstract: Some embodiments include an apparatus, method, and computer program product for Extremely High Throughput (EHT) medium reservation. Some embodiments include a first station configured to exchange EHT-Request to Send (RTS) and/or EHT-Clear to Send (CTS) capabilities with a second station, and determine CTS response mode (e.g., rules) for the first station based at least on the RTS and CTS capabilities of the first and the second stations. Some embodiments include transmitting RTS frames and receiving CTS frames in the presence of punctured channels, implementing a flexible channel reservation scheme, reserving punctured bandwidths, and receiving CTS frames even when a primary channel is busy. Some embodiments include an RTS or an CTS frame that includes an EHT bandwidth puncture (BnP) signaling address and/or a modified scrambler seed that enable channel reservations for an EHT bandwidth.

Abstract: Some aspects of this disclosure include an apparatus, method, and computer program product for wireless local area network (WLAN) link adaptation. Some aspects of this disclosure include fast feedback (FB) contents to improve WLAN link adaptation that can address the challenges of ultra-high reliability (UHR) wireless communications. Fast FB contents can include a feedback sequence number (FBSN) that identifies a reference packet and FB data corresponding to the receipt of the reference packet by the receiving device. The FB data can include link adaptation parameters corresponding to the receiving device that the transmitting device can use to adjust (e.g., adapt) subsequent transmissions to the same receiving device. Some aspects include an indicator that informs a receiving device whether to provide a Negative Acknowledgement (NACK) frame (e.g., control packets) with FB contents or not.

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.
