Abstract
LTE (Long Term Evolution) is a standard for 4G remote broadband innovations that offers enhanced network capacity and speed to mobile device users. LTE offers higher information exchange rates up to 100 Mbps downstream and 30 Mbps upstream. It also provides reduced latency, scalable bandwidth capacity and backward-compatibility with existing GSM and UMTS technology. Future developments could yield peak throughput on the order of 300 Mbps. LTE system allocates radio resources for different type of services such as real time (RT) services, non-real time (NRT) services, control signaling through a radio resource manager, and these services require dynamic resource allocation for transmitting corresponding data packets. A scheduler in radio resource manager needs to satisfy demand of these services with limited radio resources. Therefore, scheduler should be efficient in performing radio resource allocation in such dynamic environment. In this paper we are working on resource block scheduling in LTE system and proposed an algorithm to allocate resource blocks so that user’s rate requirement can be fulfilled optimally and throughput of the system can be improved. The overall performance of proposed technique is better and it enhances the network throughput up to 9.5.
