MOBILE COMMUNICATION SYSTEM, MOBILE STATION, BASE STATION, AND METHOD FOR ESTIMATING QUALITY OF COMMUNICATION PATH USED FOR THEM

摘要

PROBLEM TO BE SOLVED: To provide a mobile communication system capable of improving the system throughput.

SOLUTION: A base station 1 divides one cell into three sectors and uses an adaptive antenna to transmit a common pilot channel to a plurality of mobile stations in each sector by means of beams 101 to 103 the directivity of which is controlled by the adaptive antenna. On the other hand, when a mobile station 2 makes data communication with the base station 1, the base station 1 transmits a data channel and an individual control channel to the mobile station 2 by using a beam 201 the directivity of which is individually controlled. The mobile station 2 switches the common pilot channel and the individual control channel from the base station 1 to estimate the quality of communication paths.
