“…On the other hand, proportional fairness (PF) algorithm balances between spectral efficiency and fairness among users and makes use of users' channel condition for resource allocation (Choi and Bhak, 2007). Modified largest weighted delay first (MLWDF) algorithm, exponential (EXP) rule and logarithmic (LOG) rule algorithms use delay value as a weighting parameter for scheduling (Ramli et al, 2009;Rhee et al, 2003;Sadiq et al, 2011;Seyed et al, 2013;Stolyar and Ramanan, 2001;Wei and Tang, 2013;Xian et al, 2011). A cross layer design approach is presented in Ioannis and Stavros (2013), which makes use of both users' queue states and channel states for the allocation of resources.…”

Long-term evolution (LTE) is the broadband technology, introduced by third generation partnership project (3GPP) to support variety of multimedia services. Scheduling in LTE plays an important role to meet the system performance targets. In this paper, a new scheduling method is proposed, which considers the achievable rate based on the estimated channel condition of user in the priority metric calculation. It is highly uncertain to have perfect channel quality indicator (CQI) report at scheduler end due to poor quality of the channel and the variation of current channel condition with that of received CQI report. So, the channel condition of the user is ascertained with imperfect CQI, where the Kalman filter is used to estimate the channel condition and effectively recover the correct CQI from imperfect CQI to improve the system performance. The proposed scheduling provides better performance in terms of throughput, delay and packet loss rate (PLR) when compared with the already proposed service based scheduler (SBS) method.

“…In literature, few algorithms focus on achieving fairness among the users and others try to improve the spectral efficiency [3]. Selected algorithms use delay value as a weighting parameter for scheduling in order to satisfy the real time services, but fails to guarantee non real time services [4,5,6]. This paper proposes a three level scheduling algorithm to enhance the cell throughput while maintaining satisfied level of fairness and average user delay among users.…”

In this paper, a three level scheduling scheme is proposed for Long Term Evolution (LTE) network to enhance the cell throughput while maintaining fairness among User Equipments (UE). At initial level, the users with good channel conditions are scheduled that result in increase in cell throughput. At next level, the users with maximum delay requirements are allocated and at last level the users with long buffer queue are scheduled to maintain fairness among users. The proposed scheme is compared with traditional scheduling algorithms and validated by means of simulation results.
