Abstract: 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.

Abstract: A method of operating a wireless communication device for correcting an offset between a base station and the wireless communication device includes determining whether to perform offset correction using a first target synchronization signal block (SSB) to generate a determination result in response to changing a selected reception beam from a first reception beam to a second reception beam in an SSB period, the first target SSB being received via the second reception beam, and performing the offset correction on the second reception beam using at least one first neighbor SSB based on the determination result, the at least one first neighbor SSB being received via the first reception beam.
