    摘要: Provided are a method and an apparatus for searching control information by a terminal. The method comprises the steps of: acquiring from a base station, by means of a physical downlink control channel (PDCCH) or an upper layer message, at least one type of information being from location information on a physical control format indication channel (E-PCFICH) or location information on an E-control region; receiving the E-PCFICH based on the E-PCFICH location information; acquiring size information on the E-control region by means of the E-PCFICH; and searching E-PDCCH in the E-control region.

    摘要: Disclosed is a signal transceiving method which can reduce interference between nodes in a multi-node system. The method comprises the steps of: receiving reference signal configuration information from a first node; receiving a reference signal from a second node; measuring interference caused by the second node using the reference signal, and generating interference node information; and transmitting the interference node information to the first node, wherein the reference signal configuration information includes mapping information between the second node and the reference signal, and the interference node information includes an index of the reference signal.

    摘要: A method and apparatus of feeding back channel state information in a multi-node system are provided. The method includes receiving a reference signal of N nodes, wherein N is a natural number equal to or more than 2, aligning the N nodes in an order of preferring the N nodes based on a result of measuring the reference signal, generating channel state information for the aligned nodes, and transmitting the generated channel state information to the base station, wherein the channel state information is generated with respect to N node combinations configured from the aligned nodes, and wherein the N node combinations are obtained by adding next highest-priority nodes to a first node combination one by one, the first node combination consisting a highest-priority node among the aligned nodes.
