LTE is a promising generation of mobile communication, characterized by high data rate, lower latency in control and user plane. In the study simulation model was developed for LTE system throughput estimation for different scheduling algorithms. Conclusion of the algorithms advantages and weaknesses were made.
This paper is aimed to show the efficiency of downlink control channel (PDCCH — Physical Downlink Control Channel) utilization in LTE networks. The dramatic challenge is related to very typical case when there is no signaling resources to assign the traffic channels for users. This problem is called blocked PDCCH. In this article we are going to show the results of simulation reflecting the LTE network...
Ultra dense indoor deployment is widely recognized as one of the predominant network configurations of the future wireless systems. Dense indoor deployments are characterized by severe interference between co-channel access points deployed usually in close proximity of one another. Thus the effectiveness and efficiency of interference management techniques is the key to the success of ultra dense...
Mobile Network Operators (MNOs) are integrating carrier-grade Wireless Local Area Network (WLAN) to cellular networks to improve network performance and user experience. Access network selection (ANS) between cellular and WLAN plays a key role in the integration. Given the complexity of heterogeneous networks characterized by multiple network layer deployments and inhomogeneous traffic distribution,...
Mobility load balancing (MLB) is an important use case in the long term evolution (LTE) self-optimized networks (SON). To combat the potential Ping-Pong load transfer and low convergence issues, we propose a concurrent MLB (CLB) scheme to solve out the asymmetry traffic distribution among multiple cells and the potential hidden-cell problem. CLB is implemented among multiple source and target cells,...
