1. A method performed by a terminal in a communication system including a master base station and a secondary base station, the method comprising:
receiving, from the master base station, a first message including first configuration information for a first medium access control (MAC) entity for a first cell group associated with the master base station;
configuring the first MAC entity for the first cell group based on the first configuration information;
receiving, from the master base station, a second message including second configuration information for a second MAC entity for a secondary cell group associated with the secondary base station;
creating the second MAC entity for the secondary cell group in addition to the first MAC entity for the first cell group based on the second configuration information;
receiving, from the master base station, a third message for releasing the secondary cell group; and
releasing the secondary cell group based on the third message,
wherein the first configuration information includes configuration information for a power headroom report (PHR) for the first cell group and configuration information for a buffer status report (BSR) for the first cell group,
wherein the second configuration information includes configuration information for a PHR for the secondary cell group and configuration information for a BSR for the secondary cell group,
wherein triggering and reporting of the BSR for the first cell group and the BSR for the secondary cell group are performed independently, and
wherein the releasing the secondary cell group comprises:
resetting the second MAC entity for the secondary cell group, and
releasing a configuration for the secondary cell group.
