USER APPARATUS, BASE STATION AND COMMUNICATION SYSTEM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18214556 Titled 'USER APPARATUS, BASE STATION AND COMMUNICATION SYSTEM'
Simplified Explanation
This abstract describes a communication system that uses a multi-element antenna to transmit and receive signals between a base station device and a communication terminal device. The system includes a PHY processing unit, which is a calibration unit responsible for calibrating the phases and amplitudes of the beams formed by the antenna elements during signal transmission and reception. The PHY processing unit calculates a correction value to ensure that the phases and amplitudes of the beams are the same across all antenna elements, and then performs the calibration using this correction value.
Original Abstract Submitted
A signal is transmitted and received between a base station device and a communication terminal device that are included in a communication system, through a multi-element antenna including a plurality of antenna elements. At least one of the base station device and the communication terminal device includes a PHY processing unit that is a calibration unit that performs calibration of phases and amplitudes of beams formed by the antenna elements when the signal is transmitted and received. The PHY processing unit obtains a correction value for the phases and the amplitudes of the beams in the respective antenna elements so that the phases and the amplitudes of the beams are identical among the antenna elements, and performs the calibration based on the obtained correction value.
