Resumo
In this work we propose an algorithm to allocate resource blocks for LTE (Long Term
Evolution) communication systems that takes into account the maximum delay guarantee
and MCS (Modulation and Coding Scheme) constraints on the downlink transmission.
At first, we propose an allocation algorithm which tries to reduce user‘s delay using the
information of the network real delay and the channel transmission quality.
Next, we propose an allocation algorithm which considers the channel transmission
quality and the delay target, which is estimated through Network Calculus using service
curve and MFBAP (Multifractal Bounded Arrival Process) envelope process, in order to
decide on the scheduling of available radio resources.
Comparisons with other allocation algorithms are carried out through QoS (Quality
of Service) parameters such as average delay, total throughput, loss rate, fairness and
processing time, verifying the efficiency of the proposed algorithm.
