Method and apparatus for activating carriers in mobile communication system

摘要

A method for activating a carrier by a User Equipment (UE) in a mobile communication system supporting carrier aggregation is provided. The UE receives a Down-Link (DL) assignment from an Evolved Node B (ENB), and determines whether to activate a carrier based on the DL assignment. By doing so, the UE may perform carrier activation rapidly and efficiently.

1. A method for measuring a deactivated cell by a terminal in a mobile communication system, the method comprising:
receiving measurement information for a deactivated cell, from a base station; in performing measurement on an activated cell in an activated state, determining a measurement interval and a measurement period taking a Discontinuous Reception (DRX) operation into account and measuring the activated cell at the determined measurement interval for the determined measurement period; and in performing measurement on the deactivated cell, determining a measurement interval and a measurement period using the received measurement information related to at least one of a measurement interval and a measurement period indicated by the base station, and measuring the deactivated cell at the determined measurement interval for the determined measurement period, wherein the measurement period is acquired by the equation:
measurement period=5*measurement interval.
