Abstract: Disclosed are techniques for wireless communication. In an aspect, a network entity determines a location of a target base station and a location of at least one reference device, determines an angle-of-arrival (AoA) measurement of one or more reference signals received by at least one antenna array of the target base station from the at least one reference device, determines an expected AoA between the at least one antenna array and the at least one reference device based on the location of the target base station and the location of the at least one reference device, and determines an orientation offset of the at least one antenna array based on a difference between the expected AoA and the AoA measurement.

Abstract: A system having a locator device and a plurality of tag devices is disclosed. The locator device comprises an antenna array allowing it to determine an angle of arrival for incoming signals from each of the plurality of tag devices. The system also defines a sequence of time slots, where each time slot has a specific function. The sequence may start with a locator time slot, where the locator device transmits a packet that informs all of the tag devices that this is the start of the sequence. A sync slot follows the locator time slot, where new tag devices may transmit a sync request to the locator device. Upon receipt of a sync request, the locator device assigns the new tag device a tag slot. Following the sync slot are a plurality of tag slots, where each tag device transmits an AoA packet during its assigned tag slot.

Abstract: A method and an apparatus establish a distance as well as to a vehicle. In the method for establishing a distance between a vehicle and an infrastructure device, at least two vehicle-mounted reception devices receive a signal transmitted by the infrastructure device. Each of the vehicle-mounted reception devices contains at least two antenna elements. For each reception device, a reception device-specific distance between the vehicle and the infrastructure device is established in accordance with the antenna signals generated by the antenna elements, and the shortest of all the reception device-specific distances is established as the distance.

Abstract: Methods for determining a location of an unknown device (UD) from a plurality of known devices (KDs) are provided including receiving, at the UD, periodically broadcasted messages from each of a plurality of KDs. Corresponding arrival time stamp (Tarrival-i-UD) of each periodically broadcasted message from each of the plurality of KDs are recorded. Each of the plurality of KDs are clock synchronized to a common clock source at a master device(MD). A departure time of the periodically broadcasted message from each of the plurality of KDs is known by the UD in master device time units (Tdepart-i-md). X, y and z coordinates of a location of each of the KDs is known by the UD. The x, y and z coordinates of an actual location of the UD is calculated using the x, y and z coordinates of each of the KDs, the recorded arrival times (Tarrival-i-UD) of each of the periodically broadcasted messages from each of the plurality of KDs and the known departure times of each of the periodically broadcasted messages (Tdepart-i-md) from each of the plurality of KDs.

Abstract: In various embodiments, crowd sourcing techniques are provided to enable RTT-based positioning of UE. To address issues of discovering which beacons (e.g., Wi-Fi APs, cellular base stations, BLE transmitters, etc.) support measurement of RTT (e.g., according to IEEE 802.11mc, 3GPP Release 16, etc.), beacon RTT capabilities may be crowd-sourced from UE and maintained by a cloud-based location platform in a beacon database (or more specifically, a RTT database portion thereof). To address the issue of determining physical antenna positions, RTT measurements may be crowd-sourced from UE for those beacons that are RTT capable, and used by a trilateration algorithm (e.g., a WLS multilateration algorithm) to determine physical antenna positions, which also may be maintained in the beacon database. Accuracy of the trilateration may be enhanced by obtaining raw GNSS measurements (e.g., psuedoranges) from the UE, and performing a cloud-based RTK GNSS position fix for the UE.

Abstract: A method for calculating a time-of-arrival of a multicarrier uplink signal includes: accessing a multicarrier reference signal including a subcarrier reference signal for each subcarrier frequency in a set of subcarrier frequencies; receiving the multicarrier uplink signal transmitted from a user device, the multicarrier uplink signal including a subcarrier uplink signal for each subcarrier frequency in the set of subcarrier frequencies; for each subcarrier frequency in the set of subcarrier frequencies, calculating a phase difference, in a set of phase differences, between the subcarrier reference signal for the subcarrier frequency and a subcarrier uplink signal for the subcarrier frequency; calculating a time-of-arrival of the multicarrier uplink signal at the transceiver based on the set of adjusted phase differences; and transmitting the time-of-arrival of the multicarrier uplink signal to a remote server.

Abstract: Within several applications the ability to localize an individual within an environment is beneficial. However, existing indoor localization approaches depend upon at least one of two assumptions. First, the subject(s) localization is achieved by localizing a wireless device carried by the subject and second, wireless fingerprints are established for the localization via a site survey being performed before a system can actually localize the subject(s). However, in many application scenarios, neither of the above two assumptions are true, namely that the user is not carrying an active wireless device or that the site has been surveyed. Accordingly, embodiments of the invention provide for subject localization by a dynamic calibration of wireless signals between a receiver and a transmitter, where neither the receiver or transmitter are associated with an electronic device carried or worn by the subject.
