    Abstract: Disclosed are a data transmission device for transmitting a reference OFDM symbol generated through the application of the frequency division multiplexing to a reference symbol and a data symbol, and a data receiving device for estimating a channel by using the reference OFDM symbol. The data transmission device is capable of transmitting the reference OFDM symbol to the data receiving device more frequently without a large increase of a PAPR through the frequency multiplexing of the reference and data symbols. Therefore, the data receiving device is able to estimate the channel exactly.

    Abstract: Disclosed is a communication system which transmits ACK/NACK information on downlink data by using an uplink control channel. The communication system individually allocates radio resources for a plurality of slots included in an uplink sub frame. Consequently, uplink radio resources may be used freely, and it is even possible to flexibly handle a situation in which the amount of the ACK/NACK information is increased.

    Abstract: Disclosed is a method for generating and transmitting a reference signal in a clustered DFT-spread OFDM transmission scheme. A method for generating and transmitting a DM-RS in a clustered DFT-spread-OFDM scheme comprises: a step of generating DM-RS sequences corresponding to the number of clusters allocated for an uplink transmission; and a step of mapping the generated DM-RS sequences to the relevant DM-RS symbol positions for each cluster. Accordingly, the method for generating and transmitting a reference signal according to the present invention, in which DM-RS sequences are allocated and transmitted on a cluster basis, uses a complete DM-RS sequence for each cluster, and therefore inter-cell interference can be weakened, and problems which might occur when applied to a multi-user MIMO (MU-MIMO) scheme can be solved.

    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.
