Abstract: PURPOSE: An inter-cell interference mediating method through a wireless channel in a cellular system is provided to exchange interference mediation method between neighbor cells through a broadcasting channel. CONSTITUTION: HeNBs(Home evolved-NodeBs)(10,20) broadcast transmission power allocated to a RB(Resource Block) through a broadcast channel. The HeNBs predict an inter-cell interference value by RB with the transmission power information of neighbor cells. Cells establish a RB which wants to assign low transmission power in neighbor HeNBs. The cell transmits information about a corresponding RB to UE(User Equipment)(30,40). The UE transmit the information through UL(UpLink) to neighbor cells. The neighbor cell assigns low power to the corresponding RB.

Abstract: An interference mitigation method of a cellular system based on orthogonal frequency division multiple access is provided to improve spectrum efficiency of a cell boundary user by removing interference between cells using a multiple receiving antenna and a spreading code. A radio resource is divided into a resource group for reusing a partial frequency and a resource group for removing interference between cells(S910). The resource group for reusing a partial frequency is redivided into detailed resource groups as the number of cells for reusing a partial frequency(S920). The resource group for removing the interference between the cells in redivided into detailed resource groups according to spreading coefficient(S930). A resource of the resource group according to the spreading coefficient is allocated according to a performance requirement of a down-link control channel(S950). Each transmitting data symbol is spread to a spreading code vector coupled with each unit resource, and is transmitted by using a base resource which forms a corresponding unit resource(S960). A data symbol is restored according to the spreading coefficient by receiving desired signals or interference signals(S970).
