Minimizing delay in resource block allocation algorithm of LTE downlink

In this paper, it is proposed an algorithm to allocate resource blocks for Long Term Evolution (LTE) communication systems where it is taken into account the maximum delay guarantee and Modulation and Coding Scheme (MCS) restrictions of the downlink transmission. The proposed algorithm considers the channel quality and the delay target value for each user in order to decide on the scheduling of available radio resources. Comparisons with other allocation algorithms are carried out through statistical data in terms of Quality of Service (QoS) parameters such as average delay, loss rate, total throughput, average throughput, fairness and processing time, proving the efficiency of the proposed algorithm.
