In general, while cooperation in wireless communication networks results in performance gain, it incurs some overhead. Specifically, for our framework, this cooperation overhead includes the synchronization required among the cooperating BSs of different networks. The importance of this synchronization is due to the fact that an unsynchronized switching action among different BSs can significantly degrade system performance in terms of call blocking, for example. Such synchronization can be achieved through control signaling among the cooperating BSs.
