“…This scheduler allocates the resource blocks to the cellular users with Full-size DOI: 10.7717/peerjcs.546/fig- 3 the best link quality by combining CQI & level of fairness. It also allows the mobile users to achieve a maximum QoS because it maintains a balance between fairness and maximum cell throughput (Mamane et al, 2019). It allocates the RB by considering the throughput at a specific TTI and the average throughput of the cellular user.…”

“…Also, management of the total amount of resources is not efficient as it is not taking into account CQI factor. The reason this scheduler is widely used by many systems is the ease of implementation ( Mamane et al, 2019 ). The basic decision-making process of this scheduler is illustrated in Fig.…”

“…The higher the CQI value the better the channel condition is. Although this scheduler can increase the individual cell throughput, it suffers from the lack of fairness among cellular users ( Mamane et al, 2019 ). The cellular users that are located far from the base station (normally at the edge of the cell) would most likely never be scheduled.…”

Background Wireless links are fast becoming the key communication mode. However, as compared to the wired link, their characteristics make the traffic prone to time- and location-dependent signal attenuation, noise, fading, and interference that result in time varying channel capacities and link error rate. Scheduling algorithms play an important role in wireless links to guarantee quality of service (QoS) parameters such as throughput, delay, jitter, fairness and packet loss rate. The scheduler has vital importance in current as well as future cellular communications since it assigns resource block (RB) to different users for transmission. Scheduling algorithm makes a decision based on the information of link state, number of sessions, reserved rates and status of the session queues. The information required by a scheduler implemented in the base station can easily be collected from the downlink transmission. Methods This paper reflects on the importance of schedulers for future wireless communications taking LTE-A networks as a case study. It compares the performance of four well-known scheduling algorithms including round robin (RR), best channel quality indicator (BCQI), proportional fair (PF), and fractional frequency reuse (FFR). The performance of these four algorithms is evaluated in terms of throughput, fairness index, spectral efficiency and overall effectiveness. System level simulations have been performed using a MATLAB based LTE-A Vienna downlink simulator. Results The results show that the FFR scheduler is the best performer among the four tested algorithms. It also exhibits flexibility and adaptability for radio resource assignment.

“…Many literatures have pointed out the problem of optimal power allocation and concurrent transmission scheduling with interference reduction to maximize user throughput in 5G mm-wave HetNets [10]- [11]. Firstly, a formulation of power control and radio channel scheduling in mm-wave technology is presented in [12] without spatial multiplexing.…”

Due to the explosive growth in the density of wireless network services, applications, and technologies, optimal power consumption and radio resource management with interference mitigation can be emerged as a critical issues for future fifth-generation (5G) heterogeneous networks (HetNets). Millimeter Wave (mm-wave) technology with small cells implemented in heterogeneous 5G networks is deployed as a practical solution to deal with diverse network infrastructures, massively linked devices, and services with multi-gigabit access data rates. In this paper, we propose a jointly optimal power and concurrent radio resource transmission schedule for radio access, backhaul (BH) and Device to Device (D2D) communication links in heterogeneous 5G mmWave networks. Furthermore, for both Line Of Sight (LOS) and Non Line Of Sight (NLOS) transmission, the scheme allows different interfering and non-interfering links to transmit concurrently. Finally, Comprehensive simulations demonstrate that the proposed scheme can achieves significant improvement in terms of radio resources utilization and average user throughput.

“…By the time, the demand for high data application has increased, introducing the fourth generation 4G known as long term evolution (LTE) and offering high capacity and data for large telecommunications networks. Aiming to enable a fully connected world, 5G communication incorporates current and new infrastructures, innovative and heterogeneous technologies to satisfy the severe capability needs and guarantee maximum coverage for users in different circumstances [1]. This full connectivity is targeted not only to communicating people, but also enables the communication of machines and things that can bring evaluated value to improve the operational efficiency of the society and facilitate our everyday life [2].…”

The impending next generation of mobile communications denoted 5G intends to interconnect user equipment, things, vehicles, and cities. It will provide an order of magnitude improvement in performance and network efficiency, and different combinations of use cases enhanced mobile broadband (eMBB), ultra reliable low latency communications (URLLC), massive internet of things (mIoT) with new capabilities and diverse requirements. Adoption of advanced radio resource management procedures such as packet scheduling algorithms is necessary to distribute radio resources among different users efficiently. The proportional fair (PF) scheduling algorithm and its modified versions have proved to be the commonly used scheduling algorithms for their ability to provide a tradeoff between throughput and fairness. In this article, the buffer status is combined with the PF metric to suggest a new scheduling algorithm for efficient support for eMBB. The effectiveness of the proposed scheduling strategy is proved through à comprehensive experimental analysis based on the evaluation of different quality of service key performance indicators (QoS KPIs) such as throughput, fairness, and buffer status.
