    摘要: Disclosed are a method and an apparatus for channel estimation in a multi-node distributed system. A method for channel state estimation comprises the steps of: a terminal receiving channel state information reference signal (CSI-RS) set-up information; and the terminal calculating interference on the basis of the CSI-RS set-up information and then transmitting channel state information (CSI) based on the interference, wherein the CSI-RS set-up information may include at least one of an external interference measurement field and an internal interference measurement field. Accordingly, during the external interference and internal interference measurements, the node for use in the interference measurements may be controlled by a base station so that interference is accurately measured and feedback of accurate channel information is enabled.

    摘要: There are provided a method of user equipment searching for control information and an apparatus using the same. The method includes receiving information about the position of an Enhanced-Physical Control Format Indication Channel (E-PCFICH) from a base station, receiving an E-PCFICH based on the information about the position of the E-PCFICH, obtaining information about the frequency band of an Enhanced Physical Downlink Control Channel (E-PDCCH) region through the E-PCFICH, and searching the E-PDCCH region for an E-PDCCH for the user equipment, wherein the E-PCFICH is transmitted in an OFDM symbol between a Physical Downlink Control Channel (PDCCH), transmitted in the first N (N is one of natural numbers 1 to 4) Orthogonal Frequency Division Multiplexing (OFDM) symbols of a subframe in the time domain, and the E-PDCCH region.
