US 2020/0028556 A1 · TRANSMISSION AND RECEPTION APPARATUS

Abstract

A transmission and reception apparatus includes a plurality of antenna ports. The transmission and reception apparatus includes at least one orthogonal beam fixed beamforming circuit and a high-speed switching circuit between a transmission and reception circuit and the antenna ports. For example, the transmission and reception circuit outputs a transmission signal subjected to transmission signal processing to the high-speed switching circuit during signal transmission, the high-speed switching circuit selects at least one port from a plurality of ports provided at the orthogonal beamforming circuit, and outputs the transmission signal to the selected port, and the orthogonal beamforming circuit forms a beam corresponding to the selected port to transmit the transmission signal.
