Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate beyond a 4G communication system such as LTE. To this end, a base station using a large-scale antenna transmits, to a terminal, reference signal resource configuration information including multiple pieces of reference signal configuration information and reference signal port information, for transmission of a reference signal, and transmits the reference signal to the terminal using some or all of channel measurement resources indicated by the multiple pieces of reference signal configuration information and the reference signal port information included in the reference signal resource configuration information. In this case, the channel measurement resources may correspond to antenna ports, the number of which is indicated by a combination of the multiple pieces of reference signal configuration information and the reference signal port information.

Abstract: A method, provided by the present disclosure, of transmitting a reference signal by means of a base station in a wireless communication system using a plurality of antenna ports comprises the steps of: mapping wireless resources, for transmitting a reference signal, to a plurality of antenna ports for transmitting the reference signal; and using the wireless resources and transmitting the reference signal to a terminal through the mapped antenna ports. The step of mapping to the antenna ports is characterized by being executed on the basis of a combination of a first mapping pattern between the wireless resources and the antenna ports and a second mapping pattern between the wireless resources and the antenna ports.
