    摘要: Disclosed is a method and apparatus for RA in a cellular system. The RA in the cellular system includes receiving an RA preamble from a terminal for RA, transmitting, to the terminal, an RA response message including a sequence of the received RA preamble and uplink resource information of the terminal and overload state information with respect to the RA, receiving control information generated based on the RA response message from the terminal through the uplink resource information, and transmitting control response information with respect to the received control information.

    摘要: Disclosed is a method for allocating radio resources in a wireless communication system. Subframes that use only a particular terminal or a particular terminal group are allocated through the period, offset, and number of subframes that are consecutively used, or the subframes are allocated through the period, offset, and bitmap for subframes that are available within one or a plurality of frames, whereby radio resources are effectively allocated.

    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: Disclosed is a method in which a terminal transmits retransmission request information for an error packet of a multimedia broadcast/multicast service (MBMS), and a base station retransmits a packet in the multimedia broadcast/multicast service. The method in which the terminal transmits retransmission request information for an error packet comprises: a step of receiving an MBMS packet from the base station; a step of checking whether or not an error exists in the received MBMS packet; and a step of transmitting retransmission request information for the error packet using at least one of PUSCH, PUCCH and a random access preamble for a random access process if an error exists in the received MBMS packet. The present invention achieves improved service satisfaction among terminals located on an intercell boundary, an MBSFN boundary, and regions with a poor wireless environment.

    摘要: Disclosed is a data transmission system that transmits data by using relay. The relay may select a transmission terminal from among a plurality of terminals accessing a base station. The base station may transmit base station data to the relay during a first time slot, the transmission terminal may transmit terminal data to the relay. The relay may transmit the terminal data to the base station and may transmit the base station data to the transmission terminal during a second time slot.
