Abstract: A method of a first cell for supporting a downlink channel demodulation at a user equipment. The method according to one embodiment includes transmitting, by the first cell to the user equipment, information on a Cell-specific Reference Signal (CRS) of a second cell including at least one CRS antenna port count information of the second cell or Multicast/Broadcast over Single Frequency Network (MBSFN) subframe configuration information of the second cell; and transmitting, by the first cell to the user equipment, a downlink signal on the downlink channel. The information on the CRS of the second cell is used by the user equipment to demodulate the downlink channel.

Abstract: A method for receiving channel state information (CSI) feedback by a base station supporting multiple transmit antennas from a mobile station; the base station therefore; a method for transmitting CSI feedback by a mobile station to a base station supporting multiple transmit antennas; and the mobile station therefore are discussed. The method for receiving CSI feedback by a base station includes according to one embodiment configuring, by the base station via radio resource control (RRC) signaling, one or more channel state information-reference signal (CSI-RS) configurations and one or more null resource element (RE) configurations; transmitting CSI-RSs; and receiving the CSI feedback measured based on the CSI-RSs and the one or more null RE configurations. The one or more CSI-RS configurations are used for a channel quality measurement of the CSI feedback. The one or more null RE configurations are used for an interference measurement of the CSI feedback.

Abstract: A method and apparatus of transmitting a reference signal in a wireless communication system is provided. A reference signal sequence is generated by using a pseudo-random sequence. A portion or entirety of the reference signal sequence is mapped to at least one resource block and is transmitted. The pseudo-random sequence is generated by a gold sequence generator which is initialized with initial values obtained by using cell identifier. The reference signal provides low PAPR and high cross correlation characteristic.
