According to an embodiment of the present specification, a method for measuring a position by a terminal in a wireless communication system can be provided. The method for measuring a position by a terminal may comprise the steps of: receiving MIB information from a base station by a terminal; setting a reference for time on the basis of the received MIB information; receiving a positioning-related signal from the base station by the terminal; measuring the positioning-related signal; and acquiring distance information and orientation information of the terminal on the basis of the measured positioning-related signal. The terminal is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

A wireless animal location system is provided that identifies a location of a pet roaming within an environment using a single base unit. The wireless animal location system tracks and manages animal behavior in the environment using information of pet location.

In examples, systems and methods for direction finding of electromagnetic signals are described. The device includes a first antenna configured to receive electromagnetic energy. The device also includes a second antenna configured to separately receive the same electromagnetic energy. The device further includes a radome located in a receiving pathway of the first antenna, where the radome is configured to cause a predetermined phase shift that varies based on an angular position of the receiving pathway. The device includes 1 or more radio receivers to receive the signals independently from the antennas. Additionally, the direction finding device includes a processor configured to determine an angle of arrival of the electromagnetic energy based on a comparison of a phase of the electromagnetic energy received by the first antenna to a phase of the electromagnetic energy received by the second antenna.

An optimized system and method for determining an angle of arrival or angle of departure is disclosed. A coarse pre-search is performed to identify the general location of the incoming signal. Based on this information, a high-resolution search is performed at the general location identified in the coarse pre-search. This multi-stage approach significantly reduces the number of computations that must be performed by the device, and also reduces the amount of memory that is required to store the results of the computations. For example, a full scan may require the computations to be performed over 32,000 times. Through use of this approach, the number of computations may be reduced by over 97%. This is a similar reduction in computation time and in the amount of memory consumed by this method.
