Frequency reuse and macro diversity are both requested in 3GPP2 AIE system

but current frequency reuse schemes do not support macro diversity.In order to obtain a frequency reuse schemes with macro diversity

a novel frequency reuse scheme based on soft fiactional frequency reuse(SFER) is ptnposed.Furthermore

matterelement model

using extension set theory

is establisfted.By analyzing the model

a scheme called SFFR

supporting macro diversity

is derived.Study shows that the proposed scheme can effectively reduce the inter-cell inteferertces as well as increase spectral efficiency.Futtltemtore

perfommance of cell-edge uses is improved because of interference coordination and macro diversity gain.Simulation results show that this scheme improves average capacity of cell-edge.
