Resource Allocation in LTE: An Extensive Review on Methods, Challenges and Future Scope

With the increase in the multimedia applications that requires the high speed, high data rate in real time basis, and continuous connectivity supporting mobility. In order to facilitate effective ubiquitous or pervasive computing, stress the need for efficient utilization of the LTE characteristic. For efficient utilization of the characteristic needs focus on the maximum usability of the resource allocated. Various challenges in a different scheme of resource allocation such as downlink, uplink, and radio resources allocation is thoroughly analyzed. This paper extensively focuses basic of resource allocation, and concentrates on different kinds of issues faced by various resource allocation schemes and aims at fulfilling the needs of students, academician as well as industry in the particular aspect
