Abstract
Provided are methods and apparatuses for transmitting a buffer status report in carrier aggregation environment. The method may include receiving, from a base station, high layer signaling including information for configuring data duplicate transmission using carrier aggregation, configuring a plurality of radio link control (RLC) entities including a first RLC entity and a second RLC entity associated with one packet data convergence protocol (PDCP) entity based on the high layer signaling, and configuring a logical channel associated with the first RLC entity and a logical channel associated with the second RLC entity to one medium access control (MAC) entity; and when the data duplicate transmission is activated, transmitting, to the base station, the buffer status report including PDCP data volume in both a logical channel group associated with the first RLC entity and a logical channel group associated with the second RLC entity.
