    摘要： Provided is a communication system for a multi-cell cooperative communication. A serving base station and at least one neighboring base station may communicate with at least one terminal through mutual cooperation. Each of the serving base station and the at least one neighboring base station may shift a phase of at least one element among elements included in a precoding matrix, using a phase shift matrix, and precode at least one data symbol. A terminal may feed back preferred phase shift matrix information to the serving base station, so that the serving base station and the at least one neighboring base station may adaptively determine a phase shift matrix. The terminal may calculate the phase shift matrix with small calculation amounts. The serving base station, the at least one neighboring base station, and the terminal may pre-store a plurality of candidate matrices with respect to the phase shift matrix.

    摘要： Disclosed is a method for controlling interference in a heterogeneous network environment. The method for controlling the inter-cell interference of a base station according to one aspect of the present invention comprises the following steps: transmitting, to a terminal, information relating to subframes in which a portion of a resource is to be punctured; transmitting, to the terminal, a relevant subframe in which a portion of a resource is punctured on the basis of the information relating to said subframes. A method for controlling the inter-cell interference of a base station according to another aspect of the present invention comprises the following steps: setting a resource for transmitting system information; and transmitting system information using only said resource for transmitting system information, or preferentially using said resource for transmitting system information when transmitting system information using a subframe designated as an almost blank subframe (ABS). Accordingly, inter-cell interference problems may be alleviated even in the event pieces of important system information, such as CRS, should be transmitted using an ABS.

    摘要： 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.

    摘要： 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.
