Abstract: Methods, systems, and apparatus are presented for performing network probing. A user equipment device (UE) may store a record associating traditional service set identifiers (SSIDs) with corresponding Short SSIDs. According to some embodiments, the UE may receive a message including a Short SSID, and determine whether a corresponding full SSID is known to the UE. Based on the determination, a probe request may be generated, addressed to either the Short SSID or the full SSID. After transmitting the probe request, the UE may receive a probe response, which may include a full SSID corresponding to the Short SSID. The UE may store a record associating the full SSID with the Short SSID, if applicable. According to some embodiments, a UE may receive a plurality of messages including respective SSIDs, and may generate a single probe request addressed to the SSIDs. The UE may receive a plurality of probe responses.

Abstract: An interface circuit in an electronic device (such as an access point) may provide a wake-up-radio (WUR) discovery frame for a recipient electronic device, where the WUR discovery frame includes an operating class of a wireless local area network (WLAN) associated with the electronic device. The operating class may specify a regulatory domain and a channel set of the WLAN. Moreover, the WUR discovery frame may include an index of a channel in the channel set.

The amount of compression may be based at least in part on a communication environment of the electronic device, such as a number of electronic devices, or a number of neighboring WLANs. Thus, the WUR discovery frame may have a variable size or length.

Responses to probe requests can use extended range, legacy, single user, and/or multi user protocols.

Abstract: An interface circuit in an electronic device (such as an access point) may provide a wake-up beacon to a recipient electronic device. During operation, the interface circuit may provide a wake-up beacon associated with a predefined sub-channel in one or more channels in a band of frequencies, where the wake-up beacon is for a wake-up radio in the recipient electronic device. Moreover, the wake-up beacon may be provided within an associated time interval, such as a keep-alive interval of the electronic device. In some embodiments, the wake-up beacon includes a field with channel information that specifies one or more second channels used by a main radio in the recipient electronic device. Alternatively or additionally, the wake-up beacon may include a field with service information that specifies one or more types of services and/or a field with information specifying a transmit power of the interface circuit.

Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing block acknowledgment (BA) operations for multi-link wireless communication networks. For example some embodiments relate to an electronic device including a transceiver and one or more processors communicatively coupled to the transceiver. The one or more processors transmit, using the transceiver and to a second electronic device, a first set of one or more frames on a first link and a second set of one or more frames on a second link. The one or more processors receive, using the transceiver and from the second electronic device, a first block acknowledgment (BA) frame on the first link and a second BA frame on the second link. The one or more processors further determine, based on received first BA frame and the second BA frame, a failed or missing frame of the first set of one or more frames transmitted on the first link.

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: Some embodiments of this disclosure include apparatuses and methods for a PHY level operation that enables a transmitter and a receiver to select low-density parity check (LDPC) codewords that are HARQ retransmitted. The operations described herein provide for an increased reliability in detecting codewords at the physical (PHY) layer, as the codeword detection does not depend on detection of a media access control (MAC) protocol data unit (MPDU) start position and length. For example, the PHY layer may store failed codewords without instructions from the MAC layer. This providers for faster and simpler implementation of the PHY layer. Additionally, the operations described herein reduce overhead requirements as the MAC layer may stores a bit stream of correctly received codewords, which requires less the storage space required to store failed codewords. Furthermore, a feedback signal transmitted from a receiving device to a transmitting device may further reduce the number of retransmitted codewords.

The operations described herein provide for reducing the number of codewords that need to be retransmitted, minimizing the overhead needed to signal the feedback from a receiver to a transmitter, and allowing a transmitter to control which codewords are retransmitted.

Abstract: An interface circuit in an electronic device (such as an access point) may utilize a configurable wake-up-frame format. During operation, the interface circuit may receive a wake-up-radio (WUR)-setup request associated with a recipient electronic device, where the WUR-setup request specifies a proposed configurable wake-up-frame format. In response, the electronic device may determine the configurable wake-up-frame format to be used based at least in part on the proposed configurable wake-up-frame format. Then, the interface circuit may provide a WUR-setup response intended for the recipient electronic device, where the WUR-setup response specifies the configurable wake-up-frame format selected for use. Note that the configurable wake-up-frame format may specify a payload length in a wake-up frame and/or one or more operations of at least one of the recipient electronic device or the electronic device after the wake-up frame is transmitted by the electronic device.
