    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: Provided is a technology adopting multiple transmit antennas in a radio communication system. In a mobile communication system of a signal carrier frequency division multiple access (SC-FDMA) scheme, it is possible to transmit data using the multiple transmit antennas, while maintaining a peak to average power ratio (PAPR) to be low. Also, it is possible to provide a new transmit diversity transmission even in a general radio communication system including an orthogonal frequency division multiple access (OFDMA), a code division multiple access (CDMA) scheme, and the like.

    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: Disclosed is a method for determining the position of a terminal. The method for determining the position of a terminal belonging to an overlay network environment comprises: a step in which the terminal transmits a position determination request to a positioning server; and a step in which the terminal receives, from the positioning server, position determination support information comprising a virtual cell ID allocated to transmission points surrounding the terminal. Therefore, using this method for determining the position of a terminal enables highly accurate position determination even in an overlay network environment in which a plurality of transmission points are configured so as to have the same cell ID.
