Optimal uplink power control for dual connected users in LTE heterogeneous networks
In Dual Connectivity (DC), a User Equipment (UE) can be configured with two radio access nodes in order to aggregate the available resources at both nodes. As with dual connectivity each node has independent radio resource manage- ment, the maximum power allocation at the UE can be easily exceeded and the interference can be increased.
Hence, the power distribution among the carriers needs to be optimized and has to minimize the required coordination among the nodes. In this paper we propose an optimal power allocation based on the load of the cells and cell effective interference. Additionally, we determine criteria for configuration of UEs with dual connectivity.
The simulation results show performance improvement by the proposed algorithm with respect to the achieved user throughput. Performance gains (threefold gain in median user throughput) are evident in low as well as high loads in the cell.
