Abstract
The present disclosure relates to a wireless communication system, and more particularly to a method for transmitting a reference signal in a wireless communication system. A new structure allows coexistence of a control channel and a data cannel in one time-frequency resource, thereby increasing efficiency of resources. The data and control channels coexist using a time division scheme. The coexistent control channels reallocate regions of the control signal and reference signal to maintain reliability of the control signal. Also proposed are an auxiliary control signal for measuring or controlling inter-cell interference and a method for thereby controlling interference of a base station/terminal. A new control channel structure is designed for transmitting the auxiliary control signal, whereby enabling coexistence with the legacy terminal. This provides a method for transmission/reception of relevant information between the base station and terminals to prevent erroneous operation of the legacy terminal.
