Abstract: 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.

Abstract: Disclosed is a transmission system for transmitting reference signals with information on the state of a channel for extracting channel state information to a relay and a macro terminal. A base station transmits to the relay or the macro terminal the information on a sub-frame, which includes the channel state information reference signal. The relay and the macro terminal receive the channel state information reference signal using the information on the sub-frame. The relay and the macro terminal extract the channel state information using the channel state information reference signal, and transmit the extracted channel state information to the base station.

Abstract: A type 1 system and a type 2 system are classified according to whether carrier aggregation is used. A shared component carrier is used for both a type 1 terminal and a type 2 terminal, whereas a dedicated component carrier is used only for the type 2 terminal. Also, a type 2 base station transmits broadcast information by using a shared component carrier. In this instance, the broadcast information includes the shared broadcast information used for both the type 1 terminal and the type 2 terminal and the dedicated broadcast information only for the type 2 terminal. Also, the type 2 base station indicates component carriers that are used by the type 2 terminal, by using a semi-static component carrier indicator or a dynamic component carrier indicator.

Abstract: Disclosed is a method of using relay that may continuously transmit data without time division based on superposition coding in a communication system. When transmission of a relay-supported user signal via a base station-relay link is performed, the method of using relay based on the superposition coding reuses a resource allocated to a direct-transmission user based on the superposition coding to perform the transmission. According to example embodiments, a separate resource for the base station-relay link may not be needed, and continuous relay transmission is possible without time division, thereby substantially increasing frequency efficiency and reducing a transmission delay caused by the use of the relay.
