    摘要： Disclosed are channel management methods in a multicarrier structure in a mobile communication system. Uplink (UL) and downlink (DL) channel management methods in a carrier aggregation environment are used as the channel management methods. In DL, a base station determines a component carrier (CC) of an unstable radio channel state, stops data retransmission by the CC, and notifies a terminal of retransmission stop. In UL, the base station determines a CC of an unstable radio channel state and instructs the terminal to stop data retransmission by the CC, and the terminal stops the data retransmission and initializes a retransmission buffer. Using the channel management methods in the mobile communication system employing the multicarrier structure, an increase in the number of unnecessary retransmissions is prevented, so that unnecessary retransmission and power consumption of the terminal can be reduced and the waste of radio resources and the degradation of base station performance due to unnecessary retransmission can be prevented.

    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： Provided are an uplink transmission method and downlink transmission method in a mobile communication network including a relay. In the uplink and downlink transmission methods, frame structures and transmission timings of a backhaul downlink and a backhaul uplink are determined in consideration of at least one of a time for the relay to switch between transmission and reception and a signal transmission time. Accordingly, in a wireless communication system including a relay, it is possible to effectively perform data transmission and reception between the relay and a base station.

    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.
