Method of determining a position in a wireless communication system and apparatus thereof

摘要

A method of determining a position in a wireless communication system and apparatus thereof are disclosed. The present invention includes receiving system information including information on a reference cell and at least one neighbor cell from a location server, receiving positioning reference signals (PRSs) from the reference cell and the at least one neighbor cell using the system information, measuring reference signal time difference (RSTD) of each of the at least one neighbor cell for the reference cell, and transmitting the at least one measured RSTD to the location server. And, the RSTD is a relative timing difference between two cells. Moreover, the system information includes at least one cell for obtaining a system frame number (SFN) by the UE, as the reference cell or the at least one neighbor cell.

主权项

1. A method of determining a position of a User Equipment (UE) in a wireless communication system, comprising:
receiving, by the UE from a location server, system information including information on a reference cell for an observed time difference of arrival (OTDOA) and information on at least one neighbor cell for the OTDOA; and transmitting, by the UE to the location server, reference signal time difference (RSTD) using positioning reference signals (PRSs) received based on the system information from the reference cell and at least one neighbor cell, wherein the system information includes information on a serving cell, for which the UE can obtain a system frame number (SFN), as information on the reference cell or as information on one of the at least one neighbor cell.
