Patent number: 11585916Abstract: 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.Type: GrantFiled: April 12, 2019Date of Patent: February 21, 2023Assignee: Apple Inc.Inventors: Su Khiong Yong, Mithat C.

Publication number: 20210211894Abstract: An electronic device may be provided with wireless circuitry and control circuitry. The wireless circuitry may include a phased antenna array. Sensors and other circuitry in the electronic device may generate sensor data such as accelerometer data, gyroscope data, magnetometer data, location data, and spatial ranging data. The wireless circuitry may establish and maintain one or more wireless links with external devices based on the sensor data as the device moves over time. For example, the wireless circuitry may perform physical layer beam adjustments, inter-radio access technology handovers, intra-radio access technology handovers, and/or dual connectivity adjustments based on the sensor data. This may allow the device to maintain one or more wireless links without having to sweep the signal beam of the phased antenna array over its entire field of view each time the device has moved.Type: ApplicationFiled: March 22, 2021Publication date: July 8, 2021Inventors: Yakun Sun, Mingguang Xu, Mithat C.

Patent number: 10979251Abstract: The embodiments herein use a factorization based technique for determining filter coefficients for a subset of the subcarriers in a wireless frequency band. Once the filter coefficients for the subset of the subcarriers are calculated, the network device uses these filter coefficients to identify the filter coefficients in a neighboring subcarrier. To do so, the network device uses pseudo-inverse iteration to convert the already calculated filter coefficients into filter coefficients for a neighboring subcarrier. The network device can repeat this process for the next set of neighboring subcarriers until all the filter coefficients have been calculated.Type: GrantFiled: April 8, 2019Date of Patent: April 13, 2021Assignee: Cisco Technology, Inc.Inventors: Mithat C.

Patent number: 10931708Abstract: 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).Type: GrantFiled: September 3, 2019Date of Patent: February 23, 2021Assignee: Apple Inc.Inventors: Mingguang Xu, Mithat C.

Patent number: 10924987Abstract: 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.Type: GrantFiled: September 9, 2019Date of Patent: February 16, 2021Assignee: Apple Inc.Inventors: Su Khiong Yong, Christiaan A.

Patent number: 10720978Abstract: 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.Type: GrantFiled: September 17, 2019Date of Patent: July 21, 2020Assignee: Apple Inc.Inventors: Yakun Sun, Rohit U.

Patent number: 10660085Abstract: Communicating wireless devices collaborate and utilize waveforms to enable secure channel estimation. To protect against a repetitive replay attack, some embodiments include Single Carrier Physical Layer (SC-PHY) waveforms and/or interpolated OFDM waveforms that do not include a repeatable or predictable structure. The waveforms are transmitted in ranging packet structures that are compatible with legacy 802.11 technologies that do not utilize secure channel estimation. The ranging packets are received in combination with the information previously exchanged to enable the receiving wireless system to securely determine a channel estimate (e.g., determine a channel estimate without an interloper transmission that is not an authentic first arrival path in a multi-path channel between the wireless systems). Thus, one or both of the wireless systems can estimate the distance between them (or range). Devices utilizing legacy 802.Type: GrantFiled: March 27, 2018Date of Patent: May 19, 2020Assignee: Apple Inc.Inventors: Mingguang Xu, Su Khiong Yong, Mithat C. Dogan, Rohit U. Nabar, Qi Wang, Kyle C.
