Method and apparatus for transceiving for beam forming in wireless communication system

摘要

An electronic device for beamforming and a method thereof in a wireless communication system are provided. The electronic device includes a plurality of antennas. The electronic device also includes a plurality of transmitter and receiver switches connected to the antennas and configured to select a plurality of transmission paths and a plurality of reception paths. The electronic device further includes a plurality of first Phase Shifters (P/Ss) configured to shift a phase of Radio Frequency (RF) signals received via the antennas and the transmitter and receiver switches. The electronic device includes a combiner configured to combine the phase-shifted RF signals to one RF signal. The electronic device also includes a quadrature signal generator configured to generate a quadrature signal. The electronic device further includes a down-mixer configured to convert the quadrature signal and the combined RF signal to a first baseband signal and configured to output the first baseband signal to a modem. The electronic device includes a controller configured to control the transmitter and receiver switches, the first P/Ss, and a plurality of second P/Ss to determine a transmission or reception mode of the transmitter and receiver switches, and the phase of the RF signals transmitted and received.

1. A receiver comprising:
a plurality of switches connected to a plurality of antennas and configured to connect the plurality of antennas to a plurality of reception paths; a plurality of Phase Shifters (P/Ss) configured to shift a phase of each of a plurality of Radio Frequency (RF) signals received via the plurality of reception paths; a combiner configured to combine the plurality of phase-shifted RF signals to one RF signal; a quadrature signal generator configured to generate differential I/Q (inphase and quadrature) signals for converting the combined RF signal to a baseband signal; and a down-mixer configured to:
convert the combined RF signal to the baseband signal using the differential I/Q signals, andoutput the baseband signal to a modem.
