摘要：
A mobile communication system having a high precision frequency base station device with a high precision frequency generator, and the other low precision frequency base station device with a low precision frequency generator which receives transmission waves from the high precision frequency base station device using a transmission frequency in a prescribed frequency precision, and carries out transmission and reception by controlling transmission and reception frequencies of own station in accordance with the frequency precision of the received transmission waves. It is also fine to provide a mobile station device for a mobile station which receives the transmission waves from the high precision frequency base station device, controls a reference frequency to be a reference for transmission and reception frequencies of own station in accordance with the frequency precision of the received transmission waves, and carries out transmission and reception with respect to a base station using transmission and reception frequencies according to the controlled reference frequency, and make the low precision frequency base station device to receive the transmission waves from the mobile station device carrying out transmission and reception using the transmission and reception frequencies according to the controlled reference frequency, control a reference frequency to be a reference for transmission and reception frequencies of own station in accordance with the frequency precision of the received transmission waves, and carry out transmission and reception with respect to the mobile station using transmission and reception frequencies according to the controlled reference frequency.
