Abstract: In one set of embodiments, one or more client stations operate to configure Neighbor Awareness Networking (NAN)—direct communication with neighboring client stations, i.e., direct communication between the client stations without utilizing an intermediate access point. Embodiments of the disclosure relate to NAN datapath scheduling and NAN pre-datapath operation setup and scheduling.

The datapath model may be implemented for unicast and multicast communication between client stations.

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: Some embodiments enable secure time of flight (SToF) measurements for wireless communication packets that include secure ranging packets with zero padded random sequence waveforms, including at higher frequency bands (e.g., 60 GHz) and in non-line of sight (NLOS) scenarios. Some embodiments provide a flexible protocol to allow negotiation of one or more security parameters and/or SToF operation parameters. For example, some embodiments employ: phase tracking and signaling to support devices with phase noise constraints to mitigate phase noise at higher frequencies; determining a number of random sequences (RSs) used for SToF to support consistency checks and channel verification; additional rules supporting sub-phases of the SToF operation; and/or determining First Path (FP), Sub-Optimal, and/or Hybrid path AWV modes and the pre-conditioning usage of these modes.

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: A communication device generates a transmission signal for transmission via a wireless communication channel, wherein the transmission signal corresponds to a physical layer (PHY) data unit that conforms to a range extension mode of a first communication protocol. Generating the PHY data unit includes generating a preamble of a PHY data unit, wherein the preamble is generated to include: a legacy signal field that includes information indicating a duration of the PHY data unit, a duplicate of the legacy signal field, a plurality of subfields of a non-legacy signal field, and a plurality of additional subfields with the same data as the plurality of subfields of the non-legacy signal field. The plurality of subfields of the non-legacy signal field and the plurality of additional subfields are modulated to signal to a receiving device that the PHY data unit conforms to the range extension mode of a first communication protocol.

Abstract: A dual-radio AP including both a high-power (e.g., Wi-Fi) radio and a low-power (e.g., BLE) radio may support an assisted wakeup service for a power-limited dual-radio mobile device (STA). The power-limited STA may register with the AP for the assisted wakeup service, and may then disable its Wi-Fi radio (or otherwise initiate a lower-power mode). The power-limited STA may receive a BLE communication indicating the AP has pending Wi-Fi transmissions or updates applicable to the power-limited STA. In response, the power-limited STA may turn on its Wi-Fi radio and receive the pending transmissions or updates from the AP. If an AP does not include a low-power radio, then a high-power/low-power dual-radio STA that is not power-limited may serve as an assisted wakeup service proxy. The proxy may scan and trace the Wi-Fi beacons from the AP, and generate the BLE communication to the power-limited STA on behalf of the AP.

Some embodiments provide a flexible protocol to allow negotiation of various security parameters and SToF operation parameters. For example, some embodiments employ: phase tracking and signaling to support devices with phase noise constraints to mitigate phase noise at higher frequencies; determining a number of random sequences (RSs) used for SToF to support consistency checks and channel verification; additional rules supporting sub-phases of the SToF operation; and/or determining First Path (FP), Sub-Optimal, and/or Hybrid path AWV modes and the pre-conditioning usage of these modes.

Abstract: Timestamps associated with when transmissions are sent and received between a pair of communication devices are used to determine a distance between the pair of communication devices. The communication devices operate according to a wireless communication protocol, which specifies that a requester of a ranging measurement session is to compensate for a clock frequency offset between the pair of communication device and that a responder is not to compensate for the clock frequency offset. As part of the ranging measurement session, the responder sends feedback to the requester, where the feedback includes timestamps recorded by the responder. The timestamps in the feedback are not compensated for the clock frequency offset by the responder. After receiving the feedback, the requester compensates the timestamps in the feedback for the clock frequency offset before using the timestamps to calculate the distance between the pair of communication devices.
