Abstract :
The main challenge of LTE networks is to use unitary frequency reuse factor to achieve highest possible data throughput, however it leads to a severe interference affecting active users. Several interference mitigation techniques focus on bandwidth partitioning methods to avoid cell edge interference, although they improve user´s average SINR, such techniques reduce maximum achievable data rate. In this work, we introduce a novel resource allocation algorithm utilizing reuse one scheme whereas users are scheduled so that interference between adjacent cells´ users served at same time in same RBs is minimized. Furthermore to meet LTE networks´ low latency target, a novel algorithm is designed to obtain the optimum allocation of users with better complexity compared to well-known combinatorial optimization algorithms. Simulation results show that new proposed resource allocation algorithm improves both cell edge users´ throughput and total average throughput, and also achieves improved user´s average SINR than classic reuse one scheme.
