Title:
BASE STATION DEVICE, TERMINAL DEVICE, RADIO COMMUNICATION SYSTEM AND FREQUENCY ADJUSTMENT METHOD
Document Type and Number:
Japanese Patent JP2018061098
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a base station device, terminal device, radio communication system and frequency adjustment method, capable of suppressing generation of degradation in throughput.SOLUTION: The base station devices are a RRH 21 and a RRH 22, each of which has an information acquisition unit and a frequency control unit. The RRH 21 transmits a signal generated by using an oscillator in the RRH 21. The RRH 22 transmits a signal generated by using an oscillator in the RRH 22. The information acquisition unit acquires information of each frequency deviation in signals from the RRH 21 and the RRH 22 by communicating with a UE 31 or a UE 32 in an overlapped region of a cell 23 and a cell 24 formed by the RRH 21 and the RRH 22. The frequency control unit adjusts a frequency of each of the oscillators in the RRH 21, the RRH 22 on the basis of the information on the frequency deviation acquired by the information acquisition unit.SELECTED DRAWING: Figure 1
