Abstract: A method and an apparatus for an interference measurement method of a terminal in a mobile communication system is provided. The method includes measuring a signal component based on at least one Channel Status Information-Reference Signal (CSI-RS) allocated by a base station, measuring an interference component based on at least one Interference Measurement Resource (IMR) allocated by a base station, receiving a feedback combination configuration of the signal component and the interference component, generating feedback information including at least one of at least one Channel Quality Indicator (CQI), at least one Rank Indicator (RI), and at least one Precoding Matrix Indicator (PMI), and transmitting the feedback information to the base station.

Abstract: A control channel transmission/reception method and an apparatus for transmitting/receiving control channels using a resource allocation scheme applicable regardless of reference signal transmission or whether the reference signal is transmitted in distributed transmission mode or localized transmission mode are provided. The control channel transmission method includes mapping a Demodulation Reference Signal (DMRS) to Resource Elements (REs) of a Resource Block (RB) for transmitting a control channel, mapping the control channel to the REs numbered with numbers of predetermined number of Resource Element Groups (REGs) in a frequency-first ascending order cyclically, with the exception of the REs to which the DMRS is mapped, and transmitting the DMRS and the control channel.
