摘要

A radio base station receiving data transmission system is provided for uplink site diversity of a mobile communication system that is configured by a mobile station, radio base stations, a base station control device and a mobile communication exchange. Herein, the mobile station establishes the uplink site diversity using the radio base stations under control of the base station control device. Now, each of the radio base stations that are connected to the mobile station to receive its signals performs error detection on receiving data thereof so as to produce error information with respect to each frame. The error information contains error detection information representing occurrence of error in the receiving data and an error frequency representing a degree of error contained in the receiving data. Firstly, the base station control device receives the error information from each of the radio base stations regarding the uplink site diversity. On the basis of the error information, the device detects a radio base station that firstly reports non-error detection result within the radio base stations, or the device selects a radio base station whose amount of error in receiving data is the smallest within the radio base stations. Thus, the device requests such a radio base station to transmit its receiving data thereto. So, the receiving data are further transmitted from the base station control device to the mobile communication exchange. IMAGE
