“…An RB is of 180 kHz bandwidth and extends up to 1 ms duration. These include the Channel Aware Queue Aware (CAQA) [17], Cross-layer Based Queue-Aware (CBQA) [18], Robust M-LWDF1 (RM1) and Robust M-LWDF2 (RM2) [19] which were the modified versions of the M-LWDF algorithm. These modified versions of M-LWDF scheduling algorithms are discussed next.…”

<span lang="EN-GB">The allocation of radio resources is one of the most critical functions performed by the Radio Resource Management (RRM) mechanisms in the downlink Long Term Evolution – Advanced (LTE-Advanced). Packet scheduling concerns itself with allocation of these radio resources in an intelligent manner such that system throughput/capacity can be maximized whilst the required multimedia Quality of Service (QoS) is met. Majority of the previous studies of packet scheduling algorithms for LTE-Advanced did not take the effect of channel impairments into account. However, in real world the channel impairments cannot be obliterated completely and have a direct impact on the packet scheduling performance. As such, this work studies the impact of channel impairments on packet scheduling performance in a practical downlink LTE-Advanced. The simulation results obtained demonstrate the efficacy of RM2 scheduling algorithm over other scheduling algorithms in maximizing the system capacity and is more robust on the effect of the cellular channel impairments. </span>

“…A number of packet scheduling algorithms have been developed [11][12][13][14][15][16][17][18][19]. For example, the classic Maximum-Largest Weighted Delay First (M-LWDF) [15] is one of the packet scheduling algorithms that showed an excellent performance in the legacy wireless communication systems.…”

“…The common goal is to maximize the system throughput while achieving user QoS requirements and fairness among users. In the previous studies, the performance of the well‐known schemes are compared, and the advantage of each of them has been discussed. Ghariani and Jouaber studied the energy efficiency for popular LTE scheduling schemes and showed that M‐LWDF is more energy efficient than EXP/PF and PF, especially at ultra‐dense wireless networks.…”

“…Significant improvement in total system capacity and outage probability has been shown by the simulations. Ramli and Isa extend the M‐LWDF scheme to exploit the multicarrier transmissions (carrier aggregation) in Long Term Evolution Advanced (LTE‐A) networks. The proposed scheme manages the component carriers, modulation, and coding used on each carrier to improve QoS satisfaction and retransmission performance.…”

This paper proposes two novel packet scheduling schemes, called as throughput enhanced scheduling (TES) and TES plus (TES+), for future ultra-dense networks. These schemes introduce two novel parameters to the scheduling decision making and reformulate the parameters used by the state-of-the-art schemes. The aim is to have a more balanced weight distribution between delay and throughput-related parameters at scheduling decisions. Also include a new telecommunications related parameter into scheduling decision making that has not been studied by popular schedulers. The performance of novel schemes is compared with well-known schemes-proportional fairness (PF), exponential/proportional fairness (EXP/PF), and M-LWDF. For performance evaluation, five performance metrics-average spectral efficiency and delay, quality of service (QoS) violation ratio, jitter, and Jain's fairness index-are investigated. The simulation results show that proposed schemes can outperform all the compared scheduling schemes.

“…This video streaming traffic is delay-sensitive and demands for the provision of high transmission reliability (as described in the 3GPP specifications [5]) for a huge number of live mobile video users whilst ensuring the network performance is maximized. It was shown in [6,7] that channel and delay aware scheduling algorithms are the best candidates for meeting the desired QoS of this delay-sensitive live video streaming traffic and are hence considered in this paper.…”

This paper investigates the performance of a number of channel and delay-based scheduling algorithms for an efficient QoS (Quality of Service) provision with more live video streaming users over the Fifth Generation Long-Term Evolution-Advanced (5G LTE-A) network. These algorithms were developed for use in legacy wireless networks and minor changes were made to enable these algorithms to perform packet scheduling in the downlink 5G LTE-A. The efficacies of the EXP and M-LWDF algorithms in maximizing the number of live video streaming users at the desired transmission reliability, minimizing the average network delay and maximizing network throughput, are shown via simulations. As the M-LWDF has a simpler mathematical equation as compared to the EXP, it is more favoured for implementation in the complex downlink 5G LTE-A. ABSTRAK: Kertas ini menyiasat prestasi sebilangan saluran dan algoritma penjadualan berdasarkan kelewatan untuk penyediaan QoS (Kualiti Perkhidmatan) yang cekap dengan banyak pengguna video secara langsung melalui rangkaian Generasi Kelima Long-Term Evolution Advanced (5G LTE-A). Algoritma-algoritma yang disiasat di dalam kertas ini dicadangkan untuk digunakan dalam generasi rangkaian tanpa wayar yang lama dan sedikit perubahan dibuat untuk membolehkan algoritma ini menyokong penjadualan paket dalam downlink 5G LTE-A. Keberkesanan EXP dan M-LWDF algoritma dalam memaksimumkan jumlah pengguna pada kebolehpercayaan transmisi yang diinginkan dari streaming video secara langsung, meminimumkan kelewatan rangkaian, dan memaksimumkan truput rangkaian ditunjukkan melalui simulasi. Namun, dengan M-LWDF mempunyai formula matematik yang mudah dibandingkan dengan EXP, ia lebih sesuai untuk digunakan dalam downlink 5G LTE-A yang lebih kompleks.
