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: 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: Some embodiments include an electronic device, method, and computer program product for enabling secure time of flight (SToF) measurements for wireless communication packets that include ranging packets with zero padded random sequence waveforms, especially 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 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: This disclosure relates to methods for transmitting and receiving multi-user request-to-send and clear-to-send frames in a wireless communication system. An access point wireless device may establish wireless connections with multiple wireless devices. The access point wireless device may transmit a multi-user request-to-send frame to the wireless devices. The multi-user request-to-send frame may indicate a transmit opportunity duration and allocate frequency resource units on which to transmit clear-to-send frames to the wireless devices. The wireless devices may transmit the clear-to-send frames on the allocated frequency resource units. The clear-to-send frames can include an indication of partial or full availability for the transmit opportunity.
