Motion tracking systems and methods for determining how trackers are positioned on body members of a person, the methods including: wirelessly receiving, by a computing device, one or more first data packets of each tracker; digitally determining a first direction in which the computing device is relative to the respective tracker by computing an angle of departure of the one or more first data packets; digitally determining based on the first directions, a second direction in which each tracker is relative to one or more other trackers; and digitally determining on which body member is each tracker positioned on the person at least based on both the second directions and the body members requiring to have a tracker positioned thereon. Also, systems and methods in which angles of arrival are computed for determining the first directions.

Methods and systems are provided for dynamically adjusting broadcast beam patterns of a wavefront emitted by an antenna array based on the velocities of devices communicatively coupled to the base station associated with the antenna array. The broadcast beam patterns can be adjusted by modifying the broadcast mode or at least one phase, amplitude, or power of the at least one antenna associated with the base station. Adjusting the beam pattern, for example between multiple beams and a single unified beam, based on device types can improve the quality of service for the devices and reduce the processing burden of the base station.

This disclosure provides systems, methods, and devices for wireless communication that support enhanced positioning operations using a repeater. In a first aspect, a method of wireless communication includes receiving, by the UE, an instruction from a base station (BS) to perform a first signal measurement at a first time and a second signal measurement at a second time; determining, by the UE and based on the instruction, a first signal characteristic of a first signal during the first time corresponding to a time when a first repeater is repeating the first signal from a base station; determining, by the UE and based on the instruction, a second signal characteristic of a second signal during the second time corresponding to a time when the first repeater is not repeating the second signal; and a location of the UE is determined based on the first signal characteristic and the second signal characteristic.

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In some aspects, the apparatus may be a user equipment (UE) or a component thereof; however, in some other aspects, the apparatus may be a base station or a component thereof. The apparatus may be configured as a wireless node that configures an intermediary apparatus to reflect signals for the wireless node and another wireless node. The apparatus may be further configured to communicate a set of sensing signals with the other wireless node using the intermediary apparatus. The apparatus may be further configured to sense an object based on a set of measurements associated with the set of sensing signals.

Systems and methods for mapping location and characteristics about traffic participants are described. The systems and methods advantageously use correlative receivers for observing wireless emissions from or reflected by a plurality of traffic participants to allow for tracking geolocation and velocimetry information in real-time. The real-time geolocation and velocimetry information can be useful in autonomous vehicle navigation applications and useful for reducing computational burdens associated with tracking locations of many multiple traffic participants using direct sensor measurements, for example.

In one aspect, a process for position estimation entails obtaining (a) at least one direct distance estimate corresponding to a distance between one or more intervening devices, (b) at least one direct angle estimate corresponding to a spanning angle formed involving the one or more intervening devices, or both (a) and (b). Based on (a) the at least one direct distance estimate corresponding to the distance between devices including the one or more intervening devices, (b) the at least one direct angle estimate corresponding to the spanning angle formed involving the one or more intervening devices, or both (a) and (b), an indirect distance estimate between a first device and a second device or an indirect angle estimate involving the first device and the second device is determined. The first device and the second device may be out of range with respect to one another for a direct distance measurement.
