FIG. 12 is a block diagram showing a configuration example of the UE 3. A Radio Frequency (RF) transceiver 1201 performs analog RF signal processing to communicate with the eNB 1 and the gNB 2. The RF transceiver 1201 may include multiple transceivers. The analog RF signal processing performed by the RF transceiver 1201 includes frequency up-conversion, frequency down-conversion, and amplification. The RF transceiver 1201 is coupled to an antenna array 1202 and a baseband processor 1203. The RF transceiver 1201 receives modulated symbol data (or OFDM symbol data) from the baseband processor 1203, generates a transmission RF signal, and supplies the transmission RF signal to the antenna array 1202. Further, the RF transceiver 1201 generates a baseband reception signal based on a reception RF signal received by the antenna array 1202 and supplies the baseband reception signal to the baseband processor 1203. The RF transceiver 1201 may include an analog beamformer circuit for beam forming. The analog beamformer circuit includes, for example, multiple phase shifters and multiple power amplifiers.
