METHOD FOR MEASURING LOCATION OF USER EQUIPMENT IN WIRELESS ACCESS SYSTEM AND APPARATUS THEREFOR

摘要

The present invention relates to a method for measuring a location of user equipment in a wireless access system for supporting carrier aggregation/multiple cells and an apparatus therefor. Specifically, the method comprises the steps of: enabling the user equipment to receive information on Positioning Reference Signal (PRS) transmission bandwidths of a reference cell and a neighboring cell; enabling the user equipment to reconfigure an operating channel bandwidth of a Radio Frequency (RF) unit when one of the PRS transmission bandwidth of the reference cell and the PRS transmission bandwidth of the neighboring cell belongs to an inactive secondary cell; enabling the user equipment to receive the PRS from the reference cell and the neighboring cell; and enabling the user equipment to measure a Reference Signal Time Difference (RSTD) by using the PRS of the reference cell and the PRS of the neighboring cell. A parameter for the RSTD is configured on the basis of the smallest bandwidth among a channel bandwidth of a serving cell and the PRS transmission bandwidths of the reference cell and the neighboring cell, and the channel bandwidth of the serving cell can be determined by one of a channel bandwidth of a primary cell or a channel bandwidth of a secondary cell.
