1. A method for transmitting a signal by a transmitting apparatus in a beam forming-based communication system, the method comprisingtransmitting a first reference signal using a first transmission beam based on a first transmission period and a second reference signal using a second transmission beam based on a second transmission period,wherein a first beam width of the first transmission beam is broader than a second beam width of the second transmission beam if a first target region of the first transmission beam is closer to the transmitting apparatus than a second target region of the second transmission beam,wherein the first beam width of the first transmission beam is narrower than the second beam width of the second transmission beam if a size of the first target region of the first transmission beam is larger than a size of the second target region of the second transmission beam,wherein the size of the first target region is determined based on a first elevation angle and a first azimuth of the transmitting apparatus for the first transmission beam,wherein the size of the second target region is determined based on a second elevation angle and a second azimuth of the transmitting apparatus for the second transmission beam, andwherein the first transmission period is shorter than the second transmission period if the first beam width of the first transmission beam is broader than the second beam width of the second transmission beam.
