Performance evaluation of throughput and fairness balancing in LTE packet scheduling

Abstract

Provisioning network QoS is the essential aim in the recent cellular broadband system e.g. 4G LTE network. However, this task became a conflict when variety of user application introduced to the network, having that; each of which should be maintained with different QoS requirements. In another side, when radio resources are limited, that is very often in mobile networks nowadays, maximizing system capacity will be obtained on expense of unfair share of the resources. Therefore, motivated by the highlighted issue above, we emphasize on balancing between throughput and fairness as a key design criterion in LTE scheduling scheme. We also handle a discussion for some of the common scheduling schemes based on the above goal. A system level simulation is set up to evaluate which of the investigated schedulers can maintain the bond of fairness-throughput with a good performance.
