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 electronic device that determines a transmission schedule is described. This electronic device may include an interface circuit that communicates with a recipient electronic device. During operation, the electronic device may receive a frame with scheduling-request information that is associated with the recipient electronic device. The scheduling-request information may include a buffer status report for persistent traffic, and the frame may be compatible with an IEEE 802.11 communication protocol. For example, the frame may include a scheduling-request management frame. Alternatively, the frame may include a data frame and the scheduling-request information may be included in a media access control (MAC) frame header, such as a high-efficiency (HE) variant high-throughput (HT) control header. Then, the electronic device may determine the transmission schedule based at least in part on the scheduling-request information.

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: The present disclosure describes an electronic device configured to concurrently transmit wake-up radio (WUR) packets in a duplicated WUR transmission mode, non-duplicated WUR transmission mode, and/or mixed WUR transmission mode in one or more channels of a wideband basic service set (BSS) communication. 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.

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.

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: 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: 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 access point transmits a trigger frame to a set of electronic devices in a wireless local area network (WLAN). In response to one or more requests to send data, the access point transmits the trigger frame, which includes information specifying an ordered list of electronic devices in the set of electronic devices that are allowed to transmit, and that groups the electronic devices in the ordered list of electronic devices into a first subset of the electronic devices and a second subset of the electronic devices. Subsequently, the access point sequentially receives one or more frames from the ordered list of electronic devices, where a first group of the frames received from at least some of the first subset of the electronic devices use single-user transmission and a second group of frames received from at least some of the second subset of the electronic devices use multi-user transmission.

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.

Abstract: An electronic device that transmits a frame to a second electronic device is described. In particular, during operation, an interface circuit in the electronic device (such as an access point in a WLAN) may transmit the frame to the second electronic device using a Wi-Fi communication protocol. The frame may include information cancelling a previously specified NAV protected time in a preamble of the frame. For example, the information may include a CF-End indication. Moreover, the information may be included in a MAC header of the frame and, more generally, in a preamble of a high efficiency (HE) physical layer convergence protocol (PLCP) protocol data unit (PPDU). Furthermore, the electronic device may transmit the frame in response to a block acknowledgment (BA) from the second electronic device.

Abstract: Disclosed herein are method, system, and computer program product embodiments for utilizing multiple traffic identifiers (TIDs) in a single user (SU) transmission. 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: 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 electronic device communicates frames with an access point (AP) by receiving, from the AP, a frame header that includes information specifying a first set of tones of an OFDMA communication, the first set of tones associated with first resource block subchannels having a first bandwidth used by the AP to transmit a frame payload. The electronic device obtains a second set of tones associated with second resource block subchannels having a second bandwidth that differs from the first bandwidth, and receives the frame payload using the OFDMA communication, the second resource block subchannels, and the second set of tones. Alternatively, an electronic device dynamically switches a channel-access mode when communicating a frame with the AP depending on whether the communication includes a primary 20 MHz channel. In a technique, an MU-PPDU is communicated using a frame via a non-primary 20 MHz channel without using the primary 20 MHz channel.
