Performance Analysis of MAC Scheduler in LTE (EUTRAN) for "ASAR": Resource Allocation

Abstract

Evolved UMTS Terrestrial Radio Access Network (EUTRAN) offer high uplink and downlink throughput. This enhances user experience in term of Quality-of-Service (QoS). Radio resource allocation is a complex arrangement of resources in multiuser scenario. Generally in network, radio resources are configured in pool, however resources are offered to user on the basis of "as soon as required (ASAR)". LTE in EUTRAN provides radio resource to user, with different scheduling mechanism. This definitely reduces network capacity in whole, but at the same time increases resources availability per user at particular state of time. In every cycle of resource allocation a feedback mechanism works to cater operational resource requirement. In this paper we investigate performance of different strategies of resource allocation, driven through different scheduler such as round robin, proportional fair, best channel quality indicator (CQI), max transmission point (TP) and resource fair(RF). We evaluate strategy for resource allocation under indistinguishable arrangement and conclude with comparative performance analysis and find proportional fair offers balance throughput, fairness and spectral efficiency.
