摘要： Provided are a method and apparatus for reporting power headroom in a mobile communication system supporting carrier aggregation. A user equipment (UE) determines the maximum transmit power for each carrier and the maximum UE transmit power, and sends a power headroom report that contains power headroom for each carrier computed based on the maximum transmit power for the carrier and the maximum UE transmit power to a corresponding base station (ENB).

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.

摘要： The present invention relates to a method and apparatus for transmitting and receiving data using a plurality of carriers in a mobile communication system. The communication method by a terminal according to one embodiment of the present invention includes the steps of: receiving a secondary cell (SCell) adding command including setting information on an SCell to be added from a primary serving cell (PCell); transmitting a preamble to the SCell to be added; receiving a random access response message (RAR) for the SCell to be added; and, if the SCell adding command includes an indicator indicating that a first base station to which the SCell to be added belongs and a base station to which the PCell belongs are different from each other, applying parameters included in the RAR to the SCell that transmits the RAR. According to the embodiment of the present invention, by aggregating carriers between different base stations, a terminal can have increased chances of transmitting and receiving data at high speed through the carrier aggregation.
