Sajjad Emdadi Mahdimahalleh (Univ Akron)

TL;DR
This paper analyzes various resource scheduling schemes in LTE-Advanced with Carrier Aggregation, introducing a novel QSCS scheme that improves throughput and QoE by optimizing carrier selection based on service priority and signal quality.
Contribution
The paper proposes a new Carrier Scheduling scheme, QSCS, that enhances throughput and QoE by dynamically selecting carriers based on QoS and channel conditions, outperforming existing schemes.
Findings
QSCS improves user throughput similar to JUS.
QSCS achieves better QoE than other algorithms.
Simulation confirms effectiveness of the proposed scheme.
Abstract
In this paper I focused on resource scheduling in the downlink of LTE-Advanced with aggregation of multiple Component Carriers (CCs). When Carrier Aggregation (CA) is applied, a well-designed resource scheduling scheme is essential to the LTE-A system. Joint User Scheduling (JUS), Separated Random User Scheduling (SRUS), Separated Burst-Level Scheduling (SBLS) are three different resource scheduling schemes. JUS is optimal in performance but with high complexity and not considering quality of experience (QoE) parameters. Whereas SRUS and SBLS are contrary and users will acquire few resources because they do not support CA and the system fairness is disappointing. The author propose a novel Carrier Scheduling (CS) scheme, termed as "Quality of Service and Channel Scheduling" (QSCS). Connected CCs of one user can be changed in burst level and these changes are based on checking of…
