    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： A method and an apparatus for mapping a bit of an enhanced physical downlink control channel (e-PDCCH) in a wireless communication system are provided. A base station maps an e-PDCCH bit on a first region to which the e-PDCCH is allocated from a data region within a subframe, and maps a redundant bit of the e-PDCCH bit on a second region, which is between a control region and the first region within the subframe, including at least one orthogonal frequency division multiplexing symbol (OFDM). The e-PDCCH bit is mapped from a kth OFDM symbol within the subframe in the direction of an increasing OFDM symbol index, and the redundant bit is mapped from a (k−1)th OFDM symbol in the direction of a decreasing OFDM symbol index.
