PURPOSE: An interference arrangement method in a wireless network is provided to prevent multiplication of all crosslink channel matrixes by independently disassembling IA(interference alignment) solutions. CONSTITUTION: Three transmission apparatuses transmit known pilot signals to three reception apparatuses. Each reception apparatus estimates each channel of the transmission apparatus. The reception apparatus transmits feedback information to a target transmission apparatus. The transmission apparatus determines a pre-coding vector in another transmission apparatus. One node individually disassembles IA solutions without using a DoF(degree of freedom). Multiplication of all crosslink channel matrixes is prevented.
