Proximity based applications are becoming fastgrowing markets suggesting that Device-to-Device (D2D) communicationsis going to be an essential part of future cellularnetworks, thus studying the scalability of the system is ofparamount importance. This paper focuses on the problem ofscalability defined as finding the maximum number of D2D linksthat can share the same resources with cellular user equipments(CUEs) while assuring quality-of-service (QoS) to all users incellular networks of any size. To solve this problem a carefuldesign of interference coordination schemes is needed, thus wepresent two solutions namely full channel state information(CSI) optimal (F-CSIOp) scheme and partial CSI distributed(P-CSID) scheme. The first solution is based on an optimizationproblem that uses full CSI to maximize the number of D2Dlinks while providing QoS to all users. However implementingthis solution in real systems is infeasible due to high complexityand signaling overhead, thus we present the later solution basedon a low complexity distributed algorithm that uses limitedCSI. The results show that the P-CSID scheme is able to offerhigh spectrum efficiency and good scalability while assuring lowoutage probability to provide QoS for all users.
