    摘要: 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.

    摘要: Provided is a system of performing a random access between a base station and a terminal using a plurality of carriers. When using the plurality of carriers, an uplink carrier and a downlink carrier may be mapped to each other in 1:n or 1:1. The terminal may perform the random access based on mapping information between the uplink carrier and the downlink carrier. A random access success rate increases and thus a time used for the random access may decrease. A wireless resource may also be effectively used.

    摘要: A multicast and broadcast data transmission method is provided. The multicast and broadcast data transmission method includes transmitting, at at least one synchronized macrocell base station, Multicast and Broadcast Service (MBS) data to user equipment (UE) using radio resources allocated for MBS data transmission. Here, a relay or a small cell base station in the cell of the at least one synchronized macrocell base station keeps silent for the radio resources used for the macrocell base station to transmit MBS traffic data without performing any transmitting operation. Accordingly, it is possible to increase transmission efficiency while minimizing interference in a UE, and improve the quality of a multicast broadcast service while reducing required radio resources.

    摘要: A technology enabling a base station to transmit acknowledgement (ACK)/negative ACK (NACK) information about data received from a terminal is provided. A cyclic shift value difference of each terminal may be maximized and a radio resource for transmitting the ACK/NACK information may be assigned without collision.
