“…The system grants service providers control over linear content delivery, enables configuration of radio carriers with almost 100% capacity for broadcast services and supports large area Single Frequency Networks (SFN) with topologies beyond cellular networks [13], [14]. All this is accompanied by a significant change, as neither uplink capabilities nor registration to the provisioning network is required to consume broadcast content.…”

“…For each resource block at the base station is calculated propagation attenuation based on information from the service channels. To describe the quality of the channel at the upper levels of the base station, the resulting value of signal attenuation for a particular resource block and HTC/MTC device will turn into a modulation-code scheme (MCS) [28]. MCS is a combination of modulation (QPSK, QAM-16, QAM-64, and QAM-256) and noise coding settings.…”

In this paper, we consider the saturation problem in the 3GPP LTE cellular system caused by the expected huge number of machine-type communication (MTC) devices, leading to a significant impact on both machine-to-machine (M2M) and human-to-machine H2H traffic. M2M communications are expected to dominate traffic in LTE and beyond cellular networks. In order to address this problem, we proposed an advanced architecture designed for 5G LTE networks to enable the coexistence of H2H/M2M traffic, supported by different priority strategies to meet QoS for each traffic. The queuing strategy is implemented with an M2M gateway that manages four queues allocated to different types of MTC traffic. The optimal radio resource allocation method in LTE and beyond cellular networks was developed. This method is based on adaptive selection of channel bandwidth depending on the QoS requirements and priority traffic aggregation in the M2M gateway. Additionally, a new simulation model is proposed which can help in studying and analyzing the mutual impact between M2M and H2H traffic coexistence in 5G networks while considering high and low priority traffics for both M2M and H2H devices. This simulator automates the proposed method of optimal radio resource allocation between the M2M and H2H traffic to ensure the required QoS. Our simulation results proved that the proposed method improved the efficiency of radio resource utilization to 13% by optimizing the LTE frame formation process.

“…Xu et al [99] test the use of LDPC codes from 5G NR standard and newly designed NUCs to enable LTE-based 5G terrestrial broadcast, which is a solution expected for Release 17/18 aiming at providing convergence between broadcast and broadband networks. They present link-level simulations carried out over AWGN and TDL-B channels, and they obtain performance gains of NUCs up to 0.62 dB over the AWGN channel and up to 1.15 dB over the TDL-B channel with QAM based on Turbo codes.…”

The choice of modulation schemes is a fundamental building block of wireless communication systems. As a key component of physical layer design, they critically impact the expected communication capacity and wireless signal robustness. Their design is also critical for the successful rollout of wireless standards that require a compromise between performance, efficiency, latency, and hardware requirements. This paper presents a survey of constellation design strategies and associated outcomes for wireless communication systems. The survey discusses their performance and complexity to address the need for some desirable properties, including consistency, channel capacity, system performance, required demapping architecture, flexibility, and independence. Existing approaches for constellation designs are investigated using appropriate metrics and categorized based on their theoretical algorithm design. Next, their application to different communication standards is analyzed in context, aiming at distilling general guidelines applicable to the wireless building block design. Finally, the survey provides a discussion on design directions for future communication system standardization processes.INDEX TERMS Bandwidth, communication waveforms, mobile communications, spectral efficiency, wireless communications.
