Study of different resource allocation scheduling policy in advanced LTE with carrier aggregation

Abstract

The hugely increasing demand for mobile broadband access to internet based services will soon challenge even the Universal Mobile Telecommunication Systems (UMTS), Long Term Evolution (LTE) cellular technology and its future enhancements. The Quality of Service (QoS) provisioning is an important issue in the mobility management of wireless femtocell networks of LTE technology. According to the scheduler allocates resources, required QoS of the user with use of Resource Blocks (RBs) based on the received channel condition feedback form the User Equipments (UEs) in the form of Channel Quality Indicator (CQI). There are several scheduling algorithms are existing, but fails to meet the QoS requirement simultaneously along with scheduling disciplines for communications for public safety users that are demanded to intervene in case of special events or in post disaster area where extremely high peaks of internet capacity required. The existing study on LTE Advanced (LTE-A) scheduling is mostly limited to unidirectional method of resource allocation in Uplink Link (UL) or Down Link (DL), separately. But, there are some works on the bidirectional UL-DL scheduling in other wireless technologies. There is scope of research in the upcoming years in UL-DL joint scheduling in LTE-A system. This paper deals with Study and understanding of the existing LTE system, mainly about the different resouce allocation methods to employed and proposes a new novel algorithm for both UL and DL scheduling of resources. The proposed work aims to bring the fairness among the end users with reduced delay.
