Title:
METHOD FOR ADJUSTING PHASE OF SIGNAL TO BE INPUT TO MULTIPLE ANTENNAS, AND ELECTRONIC DEVICE IMPLEMENTING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/040554
Kind Code:
A1
Abstract:
Disclosed are various embodiments relating to a method and device for estimating the angle of a base station transmission beam by calculating the time difference between reception signals acquired through simultaneous beam sweeping to multiple antenna arrays. According to various embodiments, an electronic device may comprise: one or more first antennas; one or more second antennas spaced predetermined distance apart from the one or more first antennas; and a communication circuit electrically connected to the one or more first antennas and the one or more second antennas, wherein the communication circuit acquires a designated signal output from a base station as a first reception signal through the one or more first antennas and a second reception signal through the one or more second antennas, the first reception signal and the second reception signal are transmitted as one base station transmission beam, the time difference between the first reception signal and the second reception signal is obtained, the angle of the one base station transmission beam is calculated at least on the basis of the predetermined distance and the time difference, and the phase of a signal to be input to the one or more first antennas or the one or more second antennas is adjusted on the basis of the angle.Various embodiments are possible.
