| Summary: | The Long Term Evolution Advanced (LTE-Advanced) transmission bandwidth can be expanded by Carrier
Aggregation (CA), where CA technology expands effective bandwidth supported to User Equipment (UE) by utilizing of
radio resources across multiple carriers. Recently, many studies have been conducted on the radio resource allocation with
CA. However, most of these studies are based on Proportional Fair (PF) packet scheduling algorithms. Indeed, these
algorithms are not adequate to meet the requirements for supporting mixture real-time applications; they ignored channel
condition; and finally, they are unable to support real-time application with delay constraint. Therefore, this paper proposes
novel Packet Scheduling (PS) condition algorithm that attractively enhances the average system throughput by designing a
weighting factor to modified largest weighted delay first PS algorithm. The novel algorithm is implemented in a PS module
for LTE-Advanced via system level simulations. The results demonstrate that the effectiveness of enhanced Modified
Largest Weighted Delay First (M-LWDF) algorithm in improving throughput. |
