1. A method for operating a base station in a wireless communication system, the method comprising:
- transmitting allocation information for a plurality of beam patterns corresponding to resource periods including a first resource period and a second resource period;
transmitting first reference signals with a first beamwidth in the first resource period;
transmitting second reference signals with a second beamwidth in the second resource period;
receiving feedback information regarding channel quality for at least one of the first reference signals and the second reference signals; and
transmitting data signals through a beam pattern which is identified based on the feedback information among the plurality of beam patterns,wherein the first beamwidth is different from the second beamwidth.
