Abstract: A method for transmitting a downlink control channel in a mobile communication system and a method for mapping the control channel to physical resources using a block interleaver are provided. In order to transmit a downlink control channel in a mobile communication system, information bits are modulated to generate one or more modulation symbols according to a specific modulation scheme, the modulation symbols are interleaved using a block interleaver, and the interleaved modulated symbols are mapped to resource elements allocated for transmission of at least one control channel in a subframe, thereby transmitting the at least one control channel.

Abstract: A method for a user equipment (UE) in a wireless communication system, includes receiving channel state information reference signal (CSI-RS) for at one antenna port from a network in a subframe, wherein the CSI-RS is mapped to at least one pair of resource elements (REs) per physical resource block (PRB) pair in consecutive orthogonal frequency division multiplexing (OFDM) symbols in the subframe, and wherein the subframe includes two slots, and each slot includes six OFDM symbols based on an extended cyclic prefix (CP).
