... Intercell interference, therefore, is omnipresent throughout the network and interference man- agement strategies such as intercell interference coordination [8–12] are of utmost importance in ... each relaying scheme. The two-way relaying strategy, for instance, exhibited severe interference enhancement in both the uplink and downlink transmissions. This was not surprising since t...
