- Provided are a data transmission method in a communication system and a relay performing the same. The data transmission method in a communication system includes receiving, at a relay, an uplink buffer status report (BSR) of a terminal from the terminal, including the uplink BSR of the terminal received by the relay in an uplink BSR to be transmitted from the relay to a base station to generate a combined uplink BSR, and transmitting the combined uplink BSR to the base station even before the relay receives data stored in an uplink buffer of the terminal from the terminal. Accordingly, it is possible to reduce the transmission delay of the communication system including a relay.
