5G communication network is viewed as a “cognitive network” since it is featured by the coexistence of multiple communication systems. Therefore, cognitive radio will play a key role in 5G communication systems. In this chapter, we present interference coordination techniques for cognitive radio systems, which enable the secondary systems to exploit the spatial spectrum hole of primary systems. First, the cognitive interference network is considered, where both primary and secondary system are point-to-point MIMO. An interference coordination scheme is introduced to eliminate the interference on the primary system. Then, a cognitive uplink network is studied, where the secondary system becomes a uplink network. We present an opportunistic user scheduling scheme to improve the performance of secondary system by relaxing the interference constraint of primary system and taking advantage of multiuser diversity.
