Provided is a method of operating a wireless communication device including a phased array including a first antenna group and a second antenna group to form a beam for transmitting and receiving signals polarized in different directions, which includes receiving first signals polarized in a first direction; receiving second signals polarized in a second direction; measuring power of the first signals and power of the second signals; analyzing a relationship between a channel corresponding to the first receiving beam and a channel corresponding to the second receiving beam; estimating power of third signals that are expected to be received through the first antenna group and power of fourth signals that are expected to be received through the second antenna group; and selecting a receiving beam pattern for wireless communication.
