Downlink Interference Mitigation Scheme for Two-tier OFDMA Cellular Networks
In a two-tier cellular network, macrocells and femtocells coexist. Since femtocells use low transmission power and share network resources with macrocells, they are considered as one of the promising solutions to highly congested network environments. However, since femtocells are deployed in a selforganized manner without cell-planning, they cause severe downlink interference to macro users. T...
متن کاملDynamic Power Tuning for Downlink Interference Mitigation in Heterogeneous Lte Network
Heterogeneous Long Term Evolution (LTE) network comprising femtocells leads to cross-tier interference that arises between macrocells and femtocells in both uplink and downlink degrading the performance of the cellular system. The downlink interference from the femtocell to Macro User Equipments (MUE) being the most serious interference case is focused in this work. A power tuning technique has...
متن کاملJointly power and bandwidth allocation for a heterogeneous satellite network
Due to lack of resources such as transmission power and bandwidth in satellite systems, resource allocation problem is a very important challenge. Nowadays, new heterogeneous network includes one or more satellites besides terrestrial infrastructure, so that it is considered that each satellite has multi-beam to increase capacity. This type of structure is suitable for a new generation of commu...
متن کاملResearch on Power Control Algorithms Based on Stackelberg Game Model in Two-tier Network
With the continuous development of information, wireless network has become an integral part of people’s everyday lives. With the explosive growth of data in wireless network, the interferences and competition for resources are more and more serious, especially in the intensive network scenarios. Power control can effectively reduce the interference to improve throughput, save energy and prolon...
