“…The proposed technique provide reduction with the distance between receiver and transmitter and the channel load. In the study of Chang et al discussed the issues low throughput and high packet loss rate, which arises in LTE-A [46]. Has introduced a technique which is based on cross layer packet scheduling, and it is classified into two mechanisms: -Adaptive reward priority scheduling in MAC layer.…”

Scarce wireless resources, lead to development of cognitive radio network as a solution to unlicensed users communication in the licensed frequency band. In response to the behavior of licensed users communication, unlicensed users communication need to change from one frequency band to another band. In this communication paradigm, the performance of unlicensed users transmission control protocol gets degraded due to the features of cognitive radio network. To overcome this, several authors suggested quite a few modifications in the existing wireless transport protocol for cognitive radio network environment. This paper gives an overview of different transport protocols used for unlicensed users’ communication in cognitive radio networks.

“…But it is tough to evaluate or examine the number of arranged resource blocks exactly. The study of Chakrapani [46] has described an efficient resource scheduling framework model, which is collaborating with narrowband internet things and improved machine type communication and also using two algorithmic approaches. The proposed technique reduces the complexity of limited bandwidth and enhances the coverage LTE network.…”

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.

“…While the repeating of transmission data or control signals has been selected as a promising approach to enhance coverage of NB-IoT systems according to the 3GPP rel 13 because a larger repetition number would enhance the transmission reliability, it however results in a significant spectral efficiency loss [15].…”

Most of the current research work on the Narrowband Internet of Things (NB-IoT) is focused on enhancing its network coverage. Many of the existing NB-IoT channel coding techniques are based on repeating transmission data and control signals as a way of enhancing the network’s reliability and therefore, enabling long-distance transmissions. Although most of these efforts are made at the expense of reducing the energy consumption of the NB-IoT network, they do not always consider the channel conditions. Therefore, this work proposes a novel NB-IoT Energy-Efficient Adaptive Channel Coding (EEACC) scheme. The EEACC approach is a two-dimensional (2D) approach which not only selects an appropriate channel coding scheme based on the estimated channel conditions (dynamically classified as bad, medium or good from initial based on a periodically assessed BLER performance outcome) but also minimizes the transmission repetition number under a pre-assessed probability of successful transmission (based on the ratio of previous successful transmissions over the total number of transmissions). This results in creating a single mixed gradient based on which a higher or lower Modulating Coding Scheme (MCS) is selected on each transmission. It is aimed at enhancing the overall energy efficiency of the network by dynamically selecting the appropriate Modulation Coding Scheme (MCS) number and efficiently minimizing the transmission repetition number. Link-level simulations are performed under different channel conditions (good, medium, or bad) considerations to assess the performance of the proposed up-link adaptation technique for NB-IoT. The obtained results demonstrate that the proposed technique outperforms the existing Narrowband Link Adaptation (NBLA) as well as the traditional repetition schemes in terms of the achieved energy efficiency as well as network reliability, latency, and scalability.
