Additional configuration of small cell network data resource using common reference signal

Abstract

The present disclosure relates to a wireless communication system. The present disclosure relates to a wireless communication system supporting at least one of SC-FDMA, MC-FDMA and OFDMA, and more particularly, to a method for transmitting a reference signal in a wireless communication system. The present disclosure proposes a method for selecting, from common reference signals, a reference signal in a downlink data region and assigning the selected reference signal to a scheduling channel of the downlink data for data transfer, further proposes a method for selecting some common reference signals and diverting them to demodulation reference signals, and thereby promotes a reduction of the system overhead and an increase of data transmission capacity. Moreover, the present disclosure proposes preventing malfunction of the legacy terminals with a method for transmitting and receiving related information between terminals and base stations.
