ENHANCED SIDELINK-AIDED HYBRID NETWORK POSITIONING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18250155 titled 'ENHANCED SIDELINK-AIDED HYBRID NETWORK POSITIONING

Simplified Explanation

- The patent application describes a method for determining the position of a target user equipment (UE) using a single base station and multiple sidelink UEs with known locations. - The base station sends a reference signal to both the target UE and the sidelink UEs. - The target UE then sends sidelink signals to each sidelink UE. - By measuring the time differences between the reception and transmissions of the reference signals by the target UE, and the time difference between reception of the reference signals by the sidelink UE, a range-sum can be determined for each sidelink UE. - The range-sum represents the combined range between the target UE and the sidelink UE, and the range between the sidelink UE and the base station. - By comparing the differential in the range-sums, the position of the target UE can be determined.


Original Abstract Submitted

Position determination for a target user equipment (UE) uses a single base station and a plurality of sidelink UEs with known locations. The base station sends a reference signal to the target UE and sidelink UEs, and the target UE sends sidelink signals to each sidelink UEs. A range-sum for the range between the target UE and sidelink UE and the range between the sidelink UE and the base station can be determined for each sidelink UE, based on the time differences between the reception and transmissions of the reference signals measured by the target UE, and the time difference between reception of the reference signals measured by the sidelink UE. A differential in the range-sums can be determined and used to determine the position of the target UE.
