SIMPLIFIED CELL LOCATION INFORMATION SHARING FOR POSITIONING PURPOSES - A simplified explanation of the abstract

  • This abstract for appeared for US patent application number 18350218 Titled 'SIMPLIFIED CELL LOCATION INFORMATION SHARING FOR POSITIONING PURPOSES'

Simplified Explanation

The abstract describes techniques for determining the position of a user equipment (UE) using positioning reference signals (PRS) from multiple cells. The UE receives PRS from different cells, measures the time of arrival (TOA) of these signals, and prunes the TOA measurements based on the PRS. The UE then calculates a time difference of arrival (TDOA) vector from the pruned TOAs, which includes multiple measurements from different cells. The UE prunes the TOAs in a way that ensures the cells represented in the TDOA vector are spread out geographically, allowing for the determination of the UE's position in at least two dimensions.


Original Abstract Submitted

Disclosed are techniques to determine a position of a user equipment (UE). In an aspect, the UE receives a plurality of positioning reference signals (PRS) from a plurality of cells. The UE determines a plurality of time of arrivals (TOA) of the plurality of PRSs, and prunes the plurality of TOAs based on the plurality of PRSs. The UE then derives a time difference of arrival (TDOA) vector from the pruned TOAs. The TDOA vector includes multiple TOA related measurements of multiple cells. The UE prunes the TOAs such that the cells represented in the TDOA vector are sufficiently geographically dispersed to determine the position of the UE at least in 2D.
