Abstract: A communication system may include a wireless base station (BS), one or more user equipment (UE) devices, and optionally one or more reconfigurable intelligent surfaces (RIS's). Phased antenna arrays may be implemented on one or more of these devices. The phased antenna arrays may exhibit beam squint. The beam squint may be leveraged to optimize communications efficiency in the system. For example, a transmit device may leverage beam squint to perform modulation coding scheme (MCS) adjustment, transmit power level adjustment, reference signal allocation, beam width adjustment, frequency domain resource allocation, carrier aggregation band selection, and/or beam management procedures. Beam squint may also be leveraged to ensure that satisfactory communications are maintained between the BS and the UE devices even as the UE devices move over time.

Abstract: This disclosure relates to techniques for performing secure ranging wireless communication. A first wireless device may receive a ranging packet from a second wireless device in a wireless manner. The ranging packet may include a first random sequence portion and a second random sequence portion. The first wireless device may perform one or more channel and noise estimations for the ranging packet. The first wireless device may perform one or more security checks for the ranging packet based on any or all of the first random sequence portion, the second random sequence portion, or the channel and noise estimation(s).

Abstract: Methods for performing error recovery during a ranging procedure may include negotiation one or more ranging parameters, including a set of secure training sequences and receipt of a first ranging frame that may include a first dialog token and may have an appended first secure training sequence. The first ranging frame may be decoded based on the first dialog token but not correlated based on the first secure training sequence. 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: Methods and systems include reducing or mitigating interference by sweeping multiple beams used to communicate between a wireless network base station and an electronic device. The multiple beams include beams having different sidelobe directions. The electronic device selects, using a processor of the electronic device, a beam from the multiple beams. Furthermore, selecting the beam includes selecting the beam having a lowest level of interference of the multiple beams due to a sidelobe direction of the beam. The electronic device then communicates with the wireless network base station using the selected beam.

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.
