Abstract: Passive and active scanning for extended range wireless networking. The choice between legacy and extended range signaling can depend on one or more factors. For passive scanning, an electronic device may transmit a combination of legacy beacons and extended range beacons for network discovery by receiving electronic devices. For active scanning, an electronic device may transmit extended range probe requests in addition to legacy probe requests to discover all of the access points within its transmission range. 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: An interface circuit in an electronic device (such as an access point) may receive a wake-up-radio (WUR)-setup request associated with a recipient electronic device, where the WUR-setup request specifies one or more proposed data criteria or wake-up criteria that indicate when a wake-up frame is to be transmitted to the recipient electronic device. In response, the electronic device may determine one or more data criteria (or wake-up criteria) for use based at least in part on the one or more proposed data criteria. Then, the interface circuit may provide a WUR-setup response intended for the recipient electronic device, where the WUR-setup response indicates acceptance of the one or more proposed data criteria for use as the one or more data criteria or a proposed modification of at least one of the one or more proposed data criteria.

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.

A first acknowledgment that may include an appended second secure training sequence may be transmitted. The second secure training sequence may be associated with a prior dialog token. A second ranging frame that may include a second dialog token and may have an appended third secure training sequence may be received. The second ranging frame may be decoded based on the third dialog token and correlated based on the third secure training sequence.

Abstract: During operation, an interface circuit in an electronic device may receive, from a second electronic device (such as an access point in a WLAN), an uplink trigger frame that may specify an access category. In response to the uplink trigger frame, the electronic device may first include data associated with the specified access category in one or more frames, and then may transmit the one or more frames to the second electronic device. Moreover, when all the data associated with the specified access category has been transmitted or when there is no data associated with the specified access category, and when there is leftover time in an allocation associated with the uplink trigger frame, the interface circuit may transmit the one or more frames to the second electronic device with additional data associated with another access category that is different from the specified access category.

Abstract: An interface circuit in an electronic device (such as an access point) may provide a targeted wake-up time (TWT) service period (SP) schedule to a recipient electronic device. During operation the interface circuit may receive a TWT setup request associated with the recipient electronic device, where the TWT setup request includes non-availability information specifying one or more times when the recipient electronic device will be unavailable. For example, the non-availability information may include one or more times when the recipient electronic device has limited ability to transmit and/or receive. The interface circuit may provide a TWT setup response for the recipient electronic device, where the TWT setup response includes information specifying the TWT SP schedule for the recipient electronic device that includes at least one of: a TWT SP start time, a TWT SP duration, or an interval between TWT SPs.

Abstract: Disclosed herein are system, method, and computer program product embodiments for identity obscuration of a station (STA) connected to a wireless network to prevent the tracking of the STA. Embodiments include a STA configured to establish a security association with an access point (AP) based on an original long term identity for the station and an identity of the AP. The STA can transmit a new long term identity for the STA to the AP based on the security association. The STA can then transmit a request frame to change the original short term identity assigned to the STA to the AP. The STA can receive a response frame from the AP. The response frame can include a new short term identity assigned to the station by the AP. The STA can then map its new long term identity to its new short term identity assigned by the AP.

Abstract: This disclosure relates to methods for conducting multilink communications between a user equipment device (UE) and a wireless access point (AP) over a wireless local area network (WLAN). The UE establishes a connection with an access point through a WLAN, wherein the connection utilizes a plurality of links. The UE transmits an indication to the access point through a first link of the plurality of links, where the indication specifies one or more available links of the plurality of links that are available for the UE to receive downlink (DL) communications from the access point. The UE receives one or more DL communications from the access point through at least one of the one or more available links.

Abstract: Wireless stations may operate to configure direct communication with neighboring wireless stations (direct communication between wireless stations without an intermediate access point). Mechanisms for near-field device-to-device communications are disclosed. A wireless station may be configured to determine a minimum power level for a near-field device-to-device datapath. The wireless device may determine an average channel interference for a first discovery channel and compare the average channel interference to a first threshold. If the average channel interference is less than the first threshold, the wireless device may select a first transmission mode associated with a first power level and determine a maximum data rate for the first transmission mode.

Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing a queuing latency aware buffer status report (BSR). 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 determine an amount of data queued in a buffer for transmission over the wireless network and determine latency information associated with the queued data. The one or more processors generate a queuing latency aware buffer status report (BSR) based at least on the determined latency information. The electronic device transmits the queuing latency aware BSR to an access point.

Abstract: Some embodiments enable improved aggregated throughput and average latency in a wireless communication channel. Wireless electronic devices may implement adaptive contention window (ACW) channel access that improves channel capacity and enables latency sensitive applications (e.g., video streaming), especially when all wireless electronic devices operating on the channel as well as those in proximity utilize ACW channel access. Some embodiments detect when wireless stations on the communication channel as well as wireless stations in proximity are utilizing ACW channel access to obtain a transmit opportunity (TXOP). Based on the detection, an access point (AP) can instruct an associated wireless station to: use ACW channel access to obtain a TXOP, use a different channel access method obtain a TXOP as needed, disassociate and associate with a different AP, or use a different channel access method to obtain a TXOP.

Receiving electronic devices may be grouped together and assigned to monitor for the WUR packets. For example, the receiving electronic devices may be assigned to a position within the one or more channels to monitor for the WUR packets.

Some embodiments may operate by forming a SU multiple TID data unit that includes first data associated with a first access category and a first TID and second data associated with a second access category and a second TID. Some embodiments may further operate by transmitting the SU multiple TID data unit during a transmission opportunity based on configuration parameters associated with the transmission opportunity.

Abstract: A basic bandwidth wireless local area network (WLAN) device or station (STA) is assigned to a secondary channel. The basic bandwidth STA may be a 20 MHz STA. On the secondary channel, the basic bandwidth STA operates in a wideband mode recovering received data transmitted from an access point (AP) as part of a high bandwidth physical layer protocol data unit (PPDU). The STA and the AP can be members of a basic service set (BSS). The high bandwidth PPDU may be, for example, a 40 MHz, 60 MHz, or 80 MHz PPDU. Once on the secondary channel, the STA relies on the AP to perform channel sensing and scheduling activities, thus reducing power consumption at the STA and increasing the efficiency of the BSS. Several signaling formats are provided for indicating the secondary channel that the STA is assigned to or requests to move to.

Abstract: An access point establishes target wakeup times (TWTs) with one or more associated electronic devices in a WLAN. The access point transitions to a power-saving mode outside of the one or more TWTs. The access point maintains synchronization with the one or more electronic devices, during at least a first TWT in the one or more TWTs, by transmitting, to the one or more electronic devices, a TWT beacon that includes, or in conjunction with, synchronization information. Alternatively or additionally, during at least the first TWT, the access point transmits a multi-user trigger frame that includes the synchronization information to the one or more electronic devices. In response to the multi-user trigger frame, the access point receives data frames from the one or more electronic devices, transmits one or more acknowledgments, and transitions into the power-saving mode during a remainder of at least the first TWT.
