Abstract
The present invention relates to a method for measuring a location of a 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.
