Abstract: Disclosed is a method for signaling control information for coordinated multipoint (CoMP) transmission in a wireless communication system. The control information signaling method for CoMP transmission is performed by a base station and comprises providing, through RRC signaling, a terminal with setup information on each CSI-RS resource of a CoMP measurement group which is set in the terminal; and selectively providing, through DCI, the terminal with control information which indicates mapping of the PDSCH resource element corresponding to terminal and at least either pseudo-same positionality information of CSI-RS or pseudo-same positionality information of DM-RS. Thus, control information signaling for coordinated multipoint transmission can be efficiently performed.

Abstract: A technology enabling a terminal to receive acknowledgement (ACK)/negative ACK (NACK) information about data transmitted from the terminal is provided. The method includes receiving cyclic shift information for a reference signal from the base station; transmitting, to the base station, the data and a reference signal which is cyclic-shifted using a cyclic shift value, the cyclic shift value being determined based on a dynamic cyclic shift value mapped one-to-one to the cyclic shift information for the reference signal; and receiving, from the base station, the ACK/NACK information about the transmitted data through a radio resource of a downlink channel, the radio resource of the downlink channel being identified based on a modifier mapped one-to-one to the cyclic shift information for the reference signal.

Abstract: A reference signal (RS) transmission system to transmit a channel state information (CSI) RS for extraction of CSI to a relay and a macro terminal is disclosed. The base station transmits information on a sub frame containing the CSI RS to the relay or the macro terminal. The macro terminal and the relay receive the CSI RS using the information on the sub frame. The macro terminal and the relay extract the CSI using the CSI RS and transmit the extracted CSI to the base station.

Abstract: Provided is a method of transmitting and receiving data using a persistent allocation scheme in order to effectively support a voice service between a base station and a mobile terminal in a packet based mobile communication system. When an error occurs in transmitting control information that indicates whether to use a radio resource using the persistent allocation scheme, the base station may retransmit the control information and thereby maintain a communication quality.

Abstract: A method of transmitting and receiving a specific reference signal in single point transmission and multi-point transmission is disclosed. The specific reference signal transmission method includes determining specific reference signal transmission resources for at least one terminal targeted for transmission, and transmitting the specific reference signal using the determined transmission resources and notifying of information for a layer used by the terminal. The specific reference signal transmission method includes determining specific reference signal reception resources, receiving the information for the layer used by the terminal from a serving cell base station, and receiving the specific reference signal using the information for determined transmission resources and the layer.Therefore, the terminal can recognize a position and a sequence of the specific reference signal. Particularly, in the case of multi-user MIMO and cooperative scheduling, signal interference can be suppressed or removed using the specific reference signal of another terminal.

Abstract: A discovery method for device to device communication between terminals is disclosed. The discovery method for the device to device communication between terminals comprises the steps of: performing transmission in a first sub-frame; transmitting a discovery channel through a preset section in a second sub-frame located next to the first sub-frame; and performing transmission in a third sub-frame next to the second sub-frame. Therefore, the present invention can transmit and receive the discovery channel without colliding with other data.

Abstract: Data transmission and reception is provided by configuring control channels in a wireless communication system using a plurality of carriers. User equipment (UE) may monitor physical downlink control channel (PDCCH) candidates within common search spaces (CSSs) and User Equipment-specific search spaces (USSs). If the UE is configured with cross-carrier scheduling, when two PDCCH candidates originating from a CSS and a USS, respectively, have cyclic redundancy check (CRC) scrambled by the same Radio Network Temporary Identifier (RNTI) and have a common payload size and the same first control channel element (CCE) index, the UE may interpret that only the PDCCH originating from the CSS is transmitted, thereby solving ambiguity of downlink control information (DCI) detection.

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.
