The growing interest over the mobile based communication has attracted the Long-Term Evolution (LTE) technique which facilitates higher data transmission rates to its dynamic users. The LTE-based network involves with scheduling which governs the better communication at different traffic (large, small, medium) condition. The LTE caters up network demands and encounters some potential and unreported problems in presence of large traffic with uncertainty of its associated load. Thus, scheduling becomes most essential is must. This manuscript reviews the recent existing researches with their contribution along with significances and limitations. The paper also contributes in identify the state of art in research issues to identify the research gap towards scheduling techniques in LTE

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.

With the increasing demands of the communication performance over mobile networks, Long-Term Evolution has been observed to offer a significant contributory role by facilitating higher data transmission rates to its dynamic users. One of the core operations in the LTE-based network is scheduling which directly governs the part of communication in the presence of significant, small, medium traffic. Although there are beneficial advantages of LTE towards its catering up network demands, it too encounters some potential and unreported problems in the presence of large truck with the uncertainty of its associated load. Hence, the role of scheduling becomes most essential in this regards. This paper reviews some of the signatory work carried out in recent time and explored their contribution by measure the score of advantages as well as limitation associated with it. The paper also contributes by providing the crisp points that have been identified as the open research issues in the shape of research gap towards scheduling techniques in LTE.
