Inter-Cell Interference Cancelation Schemes Using Alternate Relay Transmission

For multicell environment, relays introduce additional interferences at the cell edge. To overcome such intercell interferences, we propose the alternate relay transmission schemes. We quantify the ergodic rate performance of the proposed schemes over Nakagami-m fading channel. Numerical results show that the proposed schemes can effectively cancel the inter-cell interference and improve the sum rate performance for cell edge users.
