Mobile station, a mobile radio communication system, and a mobile radio communication method

摘要

In a mobile radio communication method in which a mobile station moves among a plurality of base stations at high speed, in order to solve a problem of increase in the amount of operation and its related increase in the amount of power consumption and heat emission which is resulted for maintaining good communication quality of communication by the mobile station which moves at high speed to the direction for approaching the base station or moving away from it, it provides detecting means for detecting changes in relative positions to a plurality of base stations, and selecting means for selecting an uplink signal reception base station which receives an uplink signal and selecting one or plural base stations, fluctuation of increase and decrease of which of distance from own mobile station is an opposite manner compared with a case of the uplink signal receiving base station, based on changes in the relative positions detected by said detecting means as a downlink signal transmission base station which transmits a downlink signal.

主权项

1. A mobile station, comprising:
a detector for detecting changes in distances between the mobile station and a plurality of base stations; and a selector for selecting an uplink signal reception base station which receives an uplink signal, and, based on the changes in the distances detected by said detector, selecting at least one downlink signal transmission base station which transmits a downlink signal to the mobile station and whose increase and decrease of the change in the distance to the mobile station is opposite to the uplink signal reception base station.
