Method and device for transmitting and receiving data by using multiple carriers in mobile communication system

摘要

To solve the above-mentioned problem, the method for transmitting and receiving a signal by user equipment (UE) through one or more cells, according to one embodiment of the present specification, comprises the steps of: receiving, from a base station, a first message indicating whether one or more cells usable by the UE are enabled; determining which cells to enable or disable on the basis of the first message; and enabling or disabling the selected cells. According to the embodiment of the present specification, by aggregating carriers amongst different base stations, a possibility for the UE to transmit and receive high-speed data through carrier aggregation can increase.

1. A method of receiving information by a terminal in a communication system, the method including:
receiving, from a first base station, a first message including first information of at least one serving cell to be configured associated with a second base station; receiving a second message including second information indicating activation or deactivation of at least one secondary cell(SCell); activating or deactivating at least one SCell associated with the first base station based on the second message if the second message is received from the first base station; and activating or deactivating at least one SCell associated with the second base station based on the second message if the second message is received from the second base station, wherein the at least one SCell associated with the second base station is identified based on the first message and the second information received from the second base station.
