“…The conventional proportional fair (PF) scheduler is considered to be from the first category, ie, channel‐aware QoS‐unaware. However, it is considered to be the most commonly known scheduling strategy when dealing with none‐RT (NRT) traffic . The PF scheduler achieves a high level of fairness with an acceptable overall system throughput.…”

Summary Guaranteeing a certain delay threshold for delay‐sensitive applications in long term evolution (LTE) cellular communication system is a very challenging mission. By implementing an optimal scheduling strategy, this mission will be achieved. In this article, a novel scheduler is introduced in order to meet a predefined level of service quality by guaranteeing a specific delay threshold for delay‐sensitive applications in LTE cellular systems. The proposed scheduler assigns the available resource blocks (RBs) to active user equipments (UEs) tacking into consideration several attributes. The expiration date of each packet, the channel quality, the average data rate previously achieved by each UE, and the number of dropped packets for each UE compared with the average number of packets totally dropped are all considered in the proposed scheduler working mechanism. Consequently, the proposed scheduling strategy reduces the number of packets dropped for multimedia applications, and at the same time maximizes the overall throughput of the network. Simulation results are provided to study and evaluate the performance of the proposed scheduling strategy. A comparative study is presented between the proposed strategy and the most recent scheduling techniques. The obtained results prove that the proposed scheduling strategy has considerably acceptable and appreciated results compared with the results of the state‐of‐the‐art scheduling techniques.

“…However, it is considered to be the most commonly known scheduling strategy when dealing with none-RT (NRT) traffic. [24][25][26] The PF scheduler achieves a high level of fairness with an acceptable overall system throughput. Obviously, the PF scheduler cannot support the RT traffic over the LTE cellular system.…”

“…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.…”

“…In comparing (12) and (14), it should be noted that as the PSD in the conventional method is not a functional of PL, in the fractional method the term PL (α − 1) is added. Here, we find that P 0 and α are the same for the network and only PL may change for UE towards a particular cell by the eNB.…”

Summary In evolved UMTS terrestrial radio access network, long‐term evolution is known as the fourth‐generation mobile network with a leading radio performance metric as a throughput and signal‐to‐noise ratio (SNR) that affect the radio links. In this paper, we analytically describe the different long‐term evolution propagation model and measure and compare the throughput and SNR on different Doppler frequencies. To validate the performance of channel, we implement network on 3 standard models, viz, as pedestrian (EPA), vehicular (EVA), and typical urban (ETU) at different Doppler frequency (5, 70, 300, and 750 Hz), and different value of SNR (10, 13, 16, and 19 dB) on downlink channel and measured the channel throughput rate. We conclude that a performance of the channel for high SNR values severely affected by the high value of the Doppler frequency while for the channels at low SNR values is a negligible effect with high Doppler frequency.
