Dual connectivity (DC) is a promising technique to boost the user throughput performance by allowing user equipments (UEs) to receive data simultaneously from a macro cell and a small cell. In order to ensure high degree of realism and practical relevance of the results, we investigate the performance of DC in a realistic deployment based on three-dimensional data from a dense urban European capital...
Heterogeneous networks (HetNets) have been extensively discussed in 3GPP to further enhance the system throughput of traditional well-planned macrocell deployment. In this paper, we consider a HetNet scenario consisting of macro eNBs and low-power nodes implemented as remote radio heads (RRHs) or picos with dedicated carrier deployment. Collaborative inter-site carrier aggregation (CA) is proposed...
LTE-Advanced is the evolutionary path from LTE Release 8. It is designed to significantly enhance the performance of LTE Release 8 in terms of higher peak data rates, improved system capacity and coverage, and lower latency. These enhancements allow LTE-Advanced to meet or exceed the IMT-Advanced requirements and are being considered as part of LTE Release 10. In this paper, some of the physical layer...
In LTE Uplink, the slow varying pathgain and shadowing are compensated by the standardized open loop power control (OLPC) which is based on a power density offset and a compensating factor for the pathloss experienced by the users. The optimization of those parameters reveals a dependency on the allocated bandwidth. A Load Adaptive Power Control (LAPC) algorithm is proposed to handle the bandwidth...
