    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: 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.
