“…retransmissions, preemption, and packet duplication as well as multiconnectivity architectures [2]. However, the importance of time synchronization, which is a crucial component of the new RAN technologies and services, moves beyond RAN to provide an accurate time instant on a common time base to the devices and is perceived as a key enabler for cMTC applications.…”

Wireless edge is about distributing intelligence to the wireless devices wherein the distribution of accurate time reference is essential for time-critical machine-type communication (cMTC). In 5G-based cMTC, enabling time synchronization in the wireless edge means moving beyond the current synchronization needs and solutions in 5G radio access. In this article, we analyze the device-level synchronization needs of potential cMTC applications: industrial automation, power distribution, vehicular communication, and live audio/video production. We present an over-the-air (OTA) synchronization scheme comprised of 5G air interface parameters, and discuss their associated timing errors. We evaluate the estimation error in device-tobase station propagation delay from timing advance (TA) under random errors and show how to reduce the estimation error. In the end, we identify the random errors specific to dense multipath fading environments and discuss countermeasures.

“…The future 5G wireless networks require a huge capacity to connect anything-anywhere at any time. With mm-wave bands, massive multiple-input multiple-output (MIMO) and other 5G technologies, the wireless network will be able to serve the future smartphone users, robotics [22], remote surgeries [23], and autonomous cars [24,25]. Already, elevated expectations have been set for 5G by promising ultralow latency and record-breaking data speeds for consumers.…”

Comparative Study of Indoor Propagation Model Below and Above 6 GHz for 5G Wireless Networks

et al. 2019

It has been widely speculated that the performance of the next generation based wireless network should meet a transmission speed on the order of 1000 times more than the current cellular communication systems. The frequency bands above 6 GHz have received significant attention lately as a prospective band for next generation 5G systems. The propagation characteristics for 5G networks need to be fully understood for the 5G system design. This paper presents the channel propagation characteristics for a 5G system in line of sight (LOS) and non-LOS (NLOS) scenarios. The diffraction loss (DL) and frequency drop (FD) are investigated based on collected measurement data. Indoor measurement results obtained using a high-resolution channel sounder equipped with directional horn antennas at 3.5 GHz and 28 GHz as a comparative study of the two bands below and above 6 GHz. The parameters for path loss using different path loss models of single and multi-frequencies have been estimated. The excess delay, root mean square (RMS) delay spread and the power delay profile of received paths are analyzed. The results of the path loss models show that the path loss exponent (PLE) in this indoor environment is less than the free space path loss exponent for LOS scenario at both frequencies. Moreover, the PLE is not frequency dependent. The 3GPP path loss models for single and multi-frequency in LOS scenarios have good performance in terms of PLE that is as reliable as the physically-based models. Based on the proposed models, the diffraction loss at 28 GHz is approximately twice the diffraction loss at 3.5 GHz. The findings of the power delay profile and RMS delay spread indicate that these parameters are comparable for frequency bands below and above 6 GHz.

“…However, when dealing with QoS, each type of traffic will require its own QoS requirements to be guaranteed through the network. Thus, a multiplexer is interacting actively with each type of traffic depending on how urgent is the need for that type of traffic to be prioritized in terms of resource allocation Sachs et al (2019) and Aijaz et al (2018). The multiplexing technique should take into consideration the high update and packet rate compared to audio and video traffic, as it should also change its behavior not only when multiplexing and sending the data through the network but also for congestion control when it happens, the multiplexer should decide which packet to drop and which has higher priority to be passed through the channel Eid et al (2011), , and Cabrera et al (2019).…”

Tactile Internet is considered as the next step towards a revolutionary impact on the society, this is due to the introduction of different types of applications mainly the haptic ones that require strict Quality of Service guarantee especially in terms of latency. This would be a major challenge towards the design of new communication technologies and protocols in order to provide ultra-low latency. This article discusses the diverse technologies, communication protocols, and the necessary infrastructure to provide low latency based principally on the fifth generation (5G) of mobile network that is considered as the key enablers of the Tactile Internet. Furthermore, current research direction along with future challenges and open issues are discussed extensively.
