RADIO COMMUNICATION METHOD AND RADIO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To utilize frequency resources effectively by establishing an interference canceller technique in an uplink which can be realized using a realistic operation amount and circuit scale to control the number of frequency channels using the same frequency repeatedly.

SOLUTION: Steps are repeated from a first step in which channel information between a base station and a terminal station is obtained in the same cell and between different cells; a second step in which the channel information is managed as a channel matrix between a base station and a terminal station; a third step in which a reception weight matrix between a base station and a terminal station in the same cell is obtained from the channel matrix, and a matrix corresponding to the channel matrix is obtained; a fourth step in which a zero order estimation signal in the number i cell is obtained by multiplying reception information in the number i cell by a transmission weight; and a fifth step in which an "a" order estimation signal in the number j cell, where j≠i, calculated in a cell having the same frequency as the number i cell is obtained; to a sixth step in which an "a+1" order estimation signal in the number i cell is calculated by adding the estimation signal to the total regarding j of a summation result of the matrix and the estimation signal.
