US 2017/0366378 A1 · METHOD AND APPARATUS FOR DESIGNING REFERENCE SIGNAL PATTERN IN MULTI-CELL MULTI-CARRIER SYSTEM

Abstract

The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate than a 4G communication system such as LTE. The present invention relates to channel estimation and equalization in a cellular environment on the basis of an FBMC transmission and reception technique. A communication method of a base station according to one embodiment of the present invention may comprise the steps of: determining a reference signal (RS) pattern building block of a plurality of cells according to filter information of the plurality of cells; determining an RS pattern of the plurality of cells by using the determined RS pattern building block and the size of a resource block (RB); and transmitting, to a terminal, information about the determined RS pattern. According to one embodiment of the present invention, it is possible to provide a method and an apparatus for mapping a reference signal in a multi-cell environment.
