METHOD AND APPARATUS FOR COMMUNICATING BY USING DIFFERENT TYPES OF CARRIERS IN RADIO COMMUNICATION SYSTEM SUPPORTING CARRIER AGGREGATION

摘要

Provided through the present application are a method and an apparatus for use in a radio communication system, which supports carrier aggregation and carries out communication in subframe units. More specifically, user equipment operating in a first type carrier for receiving from a base station, a first piece of control information, which is related to the first type carrier and a second type carrier that support the carrier aggregation, can measure a radio signal to carry out radio resource management with respect to the first type carrier by using a first reference signal, which is included in the first type carrier, and/or a second reference signal, which is included in the second type carrier.

主权项

1. A method of performing synchronization in a wireless communication system, the method performed by a user equipment (UE) and comprising:
receiving, from a serving cell having a first carrier frequency, information on a non-serving cell having a second carrier frequency; while staying in a coverage of the serving cell, receiving, from the non-serving cell, a synchronization signal; and obtaining synchronization by using the synchronization signal from the non-serving cell.
