In this article, we study how to efficiently utilize heterogeneous network resources for various service provisioning in LTE networks with unlicensed bands. Our focus is on traffic steering, which is to intelligently distribute traffic among heterogenous cells, radio access technologies, and spectrum bands based on the desires of the network or users. We first highlight the significance of traffic...
Long Term Evolution (LTE) has been designed to deliver more data than the previous wireless and mobile systems. Failures are expected in many practical systems and they have a significant impact on the system's performance. The wireless and mobile telecommunication systems are prone to failures. The failures and repairs issues can affect the quality of service (QoS) measurements of the systems significantly...
We consider wireless femtocell networks where scheduling of transmissions is coordinated across multiple cells to mitigate interference and deliver fairness and quality of service (QoS). Coordination across multiple cells entails (i) exchange of (serving and interfering) channel information and traffic priority (which is a function of packet delays, average rate, queue length), and (ii) signalling...
Long term evolution (LTE) is the next major step towards 4th generation of mobile communications. LTE introduces a new radio access network with technologies that offer higher data rates, efficiency and quality of services as well as lower costs and the integration with the existing open standards.
