1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a first base station, first radio resource control (RRC) information on a first logical channel group (LCG), wherein the first LCG is associated with a first cell group;
receiving, from the first base station, second RRC information on a second LCG, wherein the second LCG is associated with a second cell group;
in case that at least one of logical channels contains uplink data, identifying whether a buffer status report (BSR) is triggered based on an expiration of a timer associated with the BSR, wherein the at least one of the logical channels belongs to the first LCG or the second LCG, and wherein a type of the BSR is a regular BSR; and
in case that the BSR is triggered, transmitting the BSR to the first cell group or the second cell group.
