APPARATUS AND METHOD OF UPLINK MEASUREMENT IN CARRIER AGGREGATION SYSTEM

摘要

PURPOSE: A method of uplink measurement in a carrier aggregation system is provided to flexibly perform a scheduling, and reduce the battery consumption. CONSTITUTION: A measurement signal transmission method comprises a step for confirming a plurality of component carrier waves used in a base station, a step for confirming a first component carrier wave set and a second component carrier wave set from a plurality of component carrier waves, and a step for communicating with the base station by using the first component carrier wave set. If the preset condition is satisfied, the measurement signal is transmitted to the base station through the uplink component carrier wave.
