    Abstract: A method of transmitting channel state information. The method includes receiving, from a base station, channel measurement information comprising a plurality of antenna ports to be measured for a serving cell; measuring signals related to the plurality of antenna ports based on the channel measurement information; transmitting reference signal received power (RSRP) information for the plurality of antenna ports based on the measured signals; receiving, from the base station, in response to transmission of the RSRP information, channel state information (CSI) report instruction information for a candidate of a distributed antenna port set including at least one antenna port; measuring a channel state of the at least one antenna port in the candidate; and transmitting the measured channel state to the base station, wherein the candidate of the distributed antenna port set among the plurality of antenna ports is determined based on the RSRP information by the base station.

    Abstract: A method and apparatus for transmitting Channel State Information Reference Symbol (CSI-RS) and data with partial muting of the CSI-RS are proposed. The method includes determining a CSI-RS pattern to be used among CSI-RS pattern candidates, determining a muting pattern for muting some resource elements constituting CSI-RS pattern candidates except for the determined CSI-RS pattern, mapping data symbols and CSI-RS to resource elements in a resource grid with rate patching in consideration of the CSI-RS pattern and muting pattern, and transmitting the data symbols and CSI-RS to a terminal.

    Abstract: A control information interpretation method of a terminal and a base station in a mobile communication system, and a terminal and a base station concerning the same, respectively, are provided. The control information interpretation method of a terminal includes receiving, by the terminal, control information including transport block information and antenna port related information; identifying whether a codeword 0 is enabled and a codeword 1 is disabled, or both the codeword 0 and the codeword 1 are enabled based on the transport block information; and interpreting the antenna port related information according to a result of the identification.
