Device-to-device (D2D) communications in cellular spectrum supported by a cellular infrastructure holds the promise of three types of gains. The proximity of user equipments (UE) may allow for extremely high bit rates, low delays and low power consumption [1]. The reuse gain implies that radio resources may be simultaneously used by cellular as well as D2D(More)
Due to spectrum scarcity in microwave bands used by legacy communication technologies, millimeter wave (mmWave) bands are considered as a promising enabler for 5G cellular networks to provide multi-gigabit wireless access. However, mmWave communications exhibit high attenuations, vulnerability to obstacles, and sparse-scattering environments, which are not(More)
Intercell interference coordination (ICIC) in orthogonal frequency division multiple access (OFDMA) networks in general and in the 3GPP Long Term Evolution system in particular has received much attention both from the academia and the standardization communities. Understanding the trade-offs associated with ICIC mechanisms is important, because it helps(More)
Device-to-device (D2D) communications underlaying a cellular infrastructure has recently been proposed as a means of increasing the cellular capacity, improving the user throughput and extending the battery lifetime of user equipments by facilitating the reuse of spectrum resources between D2D and cellular links. In network assisted D2D communications, when(More)
We consider the problem of link capacity dimensioning and bandwidth allocation in networks that support elastic flows and maintain proportional fairness among these flows. We assume that a certain allocated bandwidth to a user demand generates revenue for the network operator. On the other hand, the operator is incurred a capacity dependent cost for each(More)
Device-to-device (D2D) communications underlaying a cellular infrastructure has recently been proposed as a means of increasing the resource utilization, improving the user throughput and extending the battery lifetime of user equipments. In this paper we propose a new distributed power control algorithm that iteratively determines the(More)
