Abstract
The present specification discloses a mobile communication system. More particularly, the present invention relates to a method and an apparatus for transmitting and receiving data using a plurality of carriers in a mobile communication system.
Claims20
A method by a master base station in a communication system, the method comprising:
- receiving, from a terminal, a measurement report;
- determining to add at least one cell associated with a secondary base station based on the received measurement report;
- transmitting, to the secondary base station, a request for information required to add the at least one cell associated with the secondary base station;
- receiving, from the secondary base station, configuration information for a secondary cell group associated with the secondary base station in response to the request;
- and
- transmitting, to the terminal, a control message including the configuration information for a secondary cell group, wherein the configuration information for the secondary cell group is used by the terminal to configure the secondary cell group and includes configuration information for medium access control (MAC).

A method by a terminal in a communication system, the method comprising:
- transmitting, to a master base station, a measurement report;
- receiving, from a master base station, a control message including configuration information for a secondary cell group associated with a secondary base station;
- and
- configuring the secondary cell group based on the configuration information for a secondary cell group, wherein the configuration information for the secondary cell group includes configuration information for medium access control (MAC), and wherein the secondary cell group is determined based on the measurement report.

A master base station in a communication system, the master base station comprising:
- a transceiver configured to receive and transmit a signal;
- and
- a controller configured to:
- receive, from a terminal, a measurement report,
- determine to add at least one cell associated with a secondary base station based on the received measurement report,
- transmit, to the secondary base station, a request for information required to add the at least one cell associated with the secondary base station,
- receive, from the secondary base station, configuration information for a secondary cell group associated with the secondary base station in response to the request, and
- transmit, to the terminal, a control message including the configuration information for a secondary cell group, wherein the configuration information for the secondary cell group is used by the terminal to configure the secondary cell group and includes configuration information for medium access control (MAC).
5 more elements
