Power and Channel Allocation for Non-orthogonal Multiple Access in 5G Systems: Tractability and Computation
Lei Lei, Di Yuan, Chin Keong Ho +1
Network capacity calls for significant increase for 5G cellular systems. A promising multi-user access scheme, non-orthogonal multiple access (NOMA) with successive interference ca…
A Performance Study of Energy Minimization for Interleaved and Localized FDMA
Lei You, Lei Lei, Di Yuan
Optimal channel allocation is a key performance engineering aspect in single-carrier frequency-division multiple access (SC-FDMA). It is of significance to consider minimum sum pow…
Range Assignment for Power Optimization in Load-Coupled Heterogeneous Networks
Lei You, Lei Lei, Di Yuan
We consider the problem of transmission energy op- timization via range assignment for Low Power Nodes (LPNs) in Long Term Evolution (LTE) Heterogenous Networks (HetNets). The opti…
Load Balancing via Joint Transmission in Heterogeneous LTE: Modeling and Computation
Lei You, Lei Lei, Di Yuan
As one of the Coordinated Multipoint (CoMP) techniques, Joint Transmission (JT) can improve the overall system performance. In this paper, from the load balancing perspective, we s…
Optimizing Power and User Association for Energy Saving in Load-Coupled Cooperative LTE
Lei You, Lei Lei, Di Yuan
We consider an energy minimization problem for cooperative LTE networks. To reduce energy consumption, we investigate how to jointly optimize the transmit power and the association…
