Problems solved by technology
[0014] When a mobile station communicates across a plurality of base station areas, in a diversity reception system, since different base station identification signals are received at the boundary of the base station areas, the boundary of the base station areas becomes longer, or the train travels at a low speed. , there may be a problem that the signal from any base station cannot be received for a long time, and it is hoped that there is a countermeasure

The invention provides a radio communication system and a radio communication method which achieve communication of high reliability between a mobile station and a plurality of base stations. The mobile station comprises a first reception part, a second reception part, a synthesizing part for synthesizing output signals of both reception parts, a selection part for selecting output signals of bothreception parts, and a selection determination part for detecting base station identification signals of the plurality of different base stations from output signals of both reception parts. An antenna of the first reception part is placed in the front of an antenna of the second reception part in a movement direction, and the selection determination part controls selection between outputs of thefirst reception part and the second reception part in accordance with detecting the same base station identification signal or different base station identification signals from output signals of thefirst reception part and the second reception part.
Description
technical field [0001] The present invention relates to a wireless communication system and a wireless communication method, and more particularly, to a wireless communication system and a wireless communication method using a diversity reception system used for communication between a plurality of base stations and mobile stations. Background technique [0002] Conventionally, in a wireless communication system, the connection between a mobile station and a base station is generally performed by adopting a series of procedures. For different base station identification signals, the mobile station returns the received base station identification signal as a base station designation signal. According to this method, the connection can be continued when the next area is free, and since the area where the mobile station exists can be occupied, there is an advantage of high communication efficiency.
