Radio base station and program for radio base station
First Claim
1. A wireless base station with a space-division multiple access communication mechanism, comprising:
- judging means for judging whether to perform space-division multiple access communication with a first mobile station and a second mobile station according to an index showing communication quality of at least one of the two mobile stations, and communication means for performing space-division multiple access communication with the first mobile station and the second mobile station when the judging means judges to perform space-division multiple access communication.

Abstract
A wireless base station comprises a response vector calculation unit (561), an RSSI measuring unit (562), an MSE calculation unit (563), an FD calculation unit (564) and the like, and those units obtain an index showing communication quality of at least one of two mobile stations that are intended to be space-division multiplexed. According to the index, a control unit (80) judges the suitability of the two mobile stations for space-division multiplexing and performs space-division multiple access communication when judging suitable. The effect achieved with this construction is that the wireless base station maintains quality of communication between the wireless base station and mobile stations at a certain satisfactory level when performing space-division multiple access communication.

7. A wireless base station with a space-division multiple access communication mechanism, comprising:
-
judging means for judging whether to maintain space-division multiple access communication between a first mobile station and a second mobile station that are already in communication by space-division multiple access according to indices showing communication quality of the first mobile station; and
canceling means for canceling space-division multiple access communication between the first mobile station and the second mobile station when the judging means judges not to maintain the space-division multiple access communication, and wherein the indices are at least three of;
a transmission timing difference between a transmission timing of a signal from the wireless base station to the first mobile station and a transmission timing of a signal from the wireless base station to the second mobile station;
an error between a value of a signal received from the first mobile station and a value of a reference signal for the first mobile station;
a travel amount of the first mobile station per unit time;
an electric field strength of a signal received from the first mobile station;
a correlation value between a response vector of the first mobile station and a response vector of the second mobile station; and
a ratio between the electric field strength of the signal received from the first mobile station and the electric strength of a signal received from the second mobile station.
