“…The advanced UMTS Terrestrial Radio Access Network (UTRAN) in LTE facilitates a wide range of scheduling mechanisms to offer users resources. The authors Saxena et al [11] has performed a critical analysis of the performance metrics, including a) throughput, b) spectral efficiency, and c) fairness for the various schedulers that includes: a) resource fair, b) round-robin, c) best channel indicator (CQI). It is observed that though the users get more resources, overall network performance degrades.…”

Downlink scheduling is one of the essential operations when it comes to improving the quality of service in Long Term Evolution (LTE). With an increasing user base, there will be an extensive challenge in resource provisioning too. A review of existing approaches shows that there is a significant possibility of improvement in this regard, and hence, the proposed manuscript presents a benchmarking model for addressing the issues associated with Best-Channel Quality Indicator (CQI), Round Robin, and Hybrid Automatic Repeat Request (HARQ). The outcome shows HARQ scheduling to offer better performance in higher throughput, higher fairness, and lower delay over different test cases.

“…In addition, the authors concluded that the performance of CoMP is depending upon the channel imperfectness. In [8], the authors discuss an analysis of cell re-selection procedure followed in LTE and concluded that the SNR played an important role in channel allocation to UE.The authors in [9], [10] using system-level simulations compare the performance of five different media access control (MAC) scheduler under uniform LTE (EUTRAN) network in terms of key performance indicators (KPIs) for cell and UE. In [11], [12], authors discuss on the performance of proportional fair MAC scheduler over a feedback delay for EUTRAN.…”

“…They also propose CQI feedback based on a linearized model using mutual information effective SNR mapping; they calculate the average CQI per UE resources and compare performance of the scheduler in terms of fairness and throughput. Authors in [5] using system level simulations compare the performance of five different schedulers under uniform LTE (EUTRAN) network in terms of KPIs for cell and UE.…”

Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (EUTRAN) deals with high uplink and downlink throughput. The Proportional Fair (PF) Medium Access Control (MAC) scheduler offered a good balance between allocated resources and fairness among the User Equipment (UE) in comparison with other schedulers. In the PF scheduler, at each cycle of resource allocation, a feedback mechanism ensures that operational resource requirements are met while maintaining a degree of fairness among the UE. We analyze the effect of feedback Transmission Time Interval (TTI) delay on two typical EUTRAN networks, in terms of Key Performance Indicators (KPIs). One network is referred to as EUTRAN LTE and the other as EUTRAN LTE-A, which fulfils high throughput requirement. We evaluate the performance of the PF MAC scheduler for both networks under varying feedback delay in TTI. Simulated results show that the delay in TTI affects the performance of resource allocation in terms of throughput, fairness, and spectral efficiency. Feedback delay improves network performance by compensating effect of imperfect channel condition.
