Abstract: An electronic device that performs a scan is described. During operation, the electronic device may perform, using a scanning radio, the scan of a band of frequencies, where the scanning radio only receives frames. Then, the electronic device may receive, using the scanning radio, a beacon associated with a second electronic device, where the beacon includes information associated with operation of a third electronic device in a second band of frequencies. Next, the electronic device may perform, using a data radio, a second scan of the second band of frequencies based at least in part on the information, where the data radio transmits and/or receives second frames, and where the second scan is performed, at least in part, while the scan is performed. Note that the electronic device may not be associated with (or may not have a connection with) the second electronic device and/or the third electronic device.

Abstract: Systems, methods, and mechanisms for preemption of non-low latency data within an aggregated medium access control (MAC) protocol data unit (AMPDU), e.g., such as in current and future IEEE 802.11 systems. A wireless device (e.g., an access point or wireless station) may transmit, during an AMPDU, a trigger to receive (TRX) frame. The TRX frame may indicate preemption of non-low latency data intended for a first wireless station with low latency data intended for a second wireless station, e.g., via an acknowledgement policy change. Additionally, the wireless device may be configured to transmit, to the second wireless station, the low latency data within the AMPDU. Further, the wireless device may be configured to receive, after the AMPDU transmission is complete, a multi-block acknowledgement (M-BA) frame from the second wireless station. The M-BA frame and completion of the AMPDU transmission are separated by a short inter-frame space (SIFS).

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: This disclosure relates to methods for transmission preemption in a wireless local area network. A downlink transmission may be performed by an access point device on a first wireless link. Signaling requesting or indicating preemption of the downlink transmission may be provided from a non-access point device to the access point device on a second wireless link. The downlink transmission may be preempted based at least in part on the signaling requesting or indicating preemption of the downlink transmission.

Abstract: An electronic device (such as an access point) that receives a modified response frame is described. During operation, an interface circuit in the electronic device may provide a trigger frame addressed to a second electronic device, where the trigger frame includes a trigger-frame variant that is compatible with an IEEE 802.11 standard (such as IEEE 802.11ax or a subsequent IEEE 802.11 standard). Then, the interface circuit may receive a modified response frame associated with the second electronic device, where the modified response frame is different from a response frame associated with the trigger frame specified by the IEEE 802.11 standard. When the second electronic device indicates support for the modified response frame during association with the electronic device, the interface circuit may define parameters associated with the modified response frame in an association response.

Abstract: An electronic device (such as an access point) that receives a modified response frame is described. During operation, an interface circuit in the electronic device may provide a management frame addressed to a second electronic device. Then, the interface circuit may provide a trigger frame addressed to the second electronic device, where the trigger frame includes a trigger-frame variant that is compatible with an IEEE 802.11 standard. Next, the interface circuit may receive a modified response frame associated with the second electronic device, where the modified response frame is different from a response frame associated with the trigger frame specified by the IEEE 802.11 standard, and modifications to the modified response frame are specified in the management frame.

Abstract: An electronic device (such as an access point) is described. This electronic device transmits an orthogonal frequency division multiple access (OFDMA) frame to a recipient electronic device (such as a client or a station). The OFDMA frame includes multiple predefined resource units (RUs) allocated to the recipient electronic device in a set of predefined RUs having associated frequency bandwidths. Moreover, the multiple predefined RUs include two or more first predefined RUs having a first number of tones less than a predefined amount, or two or more second predefined RUs having a second number of tones greater than or equal to the predefined amount. For example, the predefined amount may include 242 tones. Note that the multiple predefined RUs may have the same or different numbers of tones. Moreover, the electronic may receive an acknowledgment or a block acknowledgment from the recipient electronic device.
