Small cell is an emerging and promising technology for improving hotspots coverage and capacity, which tends to be densely deployed in populated areas. However, in a dense small cell network, the performances of users differ vastly due to the random deployments and the interferences. To guarantee fair performance among users in different cells, we propose a new distributed strategy for fairness constrained...
The authors consider the joint admission and power control problem in a dense small cell network, which contains multiple interference links. The goal is to mainly maximise the number of the admitted links, and at the same time minimise the transmit power. The authors formulate the admission control and power control problem as a joint optimisation problem, which is however non-deterministic polynomial...
Device-to-Device (D2D) communication is proposed as a promising remedy to improve the quality-of-service (QoS) for communicating user equipments (UEs) in proximity by reusing the spectrum of cellular system. Meanwhile, energy conservation receives great attention for D2D UEs owing to the battery-driven feature and undesirable cross-tier interference. So, we leverage about performance tradeoff and...
Device-to-Device (D2D) communication can greatly enhance the system throughput (ST) and individual quality-of-service (QoS) experience by reusing the spectrum of cellular network. But due to dense spectrum sharing, severe co-channel interference may be imposed between cellular links (C-links) and D2D links (D-links). So, to fully utilize the gain of D2D communication, we attempt to maximize the ST...
