“…Although it is possible to adopt the widely used cryptography algorithms, this may results into high-complexity signal processing and then not suitable for URLLCs, especially for IoT devices with low computing capacities. Recently, the adoption of physicallayer security (PLS) has been recognised a valid solution against eavesdropping attacks in URLLCs [75], [76]. Furthermore, the LoS-dominated UAV channel plays an important for physical layer keys generation aimed (PLKG) to generate the secret keys to protect the confidential information exchanged between transceivers [77].…”

Ultra-reliable low-latency communications (URLLCs) and the adoption of unmanned aerial vehicles (UAVs) for network coverage improvement have emerged as key enabling communication paradigms for the successful deployment of mobile communication services envisioned in both the fifthgeneration (5G) and the sixth-generation (6G) networks. This paper provides a comprehensive survey about the current state-of-the-art (SoA) on UAV-enabled URLLC networks. The core idea is to highlight the main characteristics of this new network concept as well as its critical aspects. We first perform an overview of URLLC by illustrating the main features and related implementation chellenges. Subsequently, an indepth discussion on UAV-enabled networks is provided, with a special emphasis on how URLLCs and UAV communication can be classified as complementary paradigms. Finally, a comprehensive analysis and classification of the current research advancements on UAV-enabled URLLCs networks is carried out. This paper is concluded by pointing out some the open challenges and our visions related to future directions which should be undertaken in order to pave the way towards the practical implementation of this promising network architecture.INDEX TERMS Beyond fifth-generation (5G) , Ultra-reliable low-latency communications (URLLCs), unmanned aerial vehicles (UAVs) I.

In 2030, 6G is going to bring remarkable revolution in communication technologies as it will enable Internet of Everything. Still many countries are working over 5G and B5G has yet to be developed, while some research groups have already initiated projects on 6G. 6G will provide high and sophisticated QoS e.g. virtual reality and holographic communication. At this stage, it is impossible to speculate every detail of 6G and which key technologies will mark 6G. The wide applications of ICT, such as IoT, AI, blockchain technology, XR (Extended Reality) and VR (Virtual Reality), has created the emergence of 6G technology. On the basis of 5G technique, 6G will put profound impact over ubiquitous connectivity, holographic connectivity, deep connectivity and intelligent connectivity. Notably, research fraternity should focus on challenges and issues of 6G. They need to explore various alternatives to meet desired parameters of 6G. Thus, there are many potential challenges to be envisioned. This review study outlines some future challenges and issues which can hamper deployment of 6G. We subsequently define key potential features of 6G to provide the state of the art of 6G technology for future research. We have provided a review of extant research on 6G. In this review, technology prospects, challenges, key areas and related issues are briefly discussed. In addition, we have provided technologies breakdown and framework of 6G. We have shed light over future directions, applications and practical considerations of 6G to help researchers for possible breakthroughs. Our aim is to aggregate the efforts and eliminate the technical uncertainties towards breakthrough innovations for 6G.

“…Physical layer authentication (PLS) using L1 information is a good choice since it could remove the time-consuming functionalities of security protection for SRB0 and merely focus on inherent security advantages at L1 to bring lightweight overheads and desirable security performance [11]. Authors in [16] have analyzed the advantages of using physical layer information to protect URLLC. Previously, lots of research of PLS in [17], [18] have been done by employing channel state information (CSI) which is usually estimated using pilots.…”

“…Authors in [32] also concluded that the technique of encoding SAPs to carry information in parallel with data transmission can improve the system reliability with less power and complexity, making it a very suitable candidate for 5G URLLC service. This technique was also studied in grant-free URLLC systems in [16]. Those schemes provide a road access to TRP using SAPs.…”

Concatenated Graph Coding on Bandwidth Part for Secure Pilot Authentication in Grant-Free URLLC

Grant-free multiple access is a critical mechanism introduced in 5G new radio (NR) to support ultra-reliable low-latency communication (URLLC) services. Pilot authentication (PA) is a key security mechanism to guarantee reliable performance of grant-free URLLC. However, PA can be easily paralyzed by pilot-aware attack since pilot signals are usually publicly known and unprotected. To solve this, we develop the concatenated graph coding (CGC) theory by which time-frequency resources on bandwidth part (BWP) can be encoded flexibly to protect PA securely. Particularly, we use bipartite graph and multigraph theory to model PA on BWP as transmission and retrieval of pilot (TRP). Each transmitter in the uplink needs transmit a unique random pilot sequence as subcarrier activation pattern (SAP) on BWP. After observing SAPs from multiple transmitters, the receiver decodes a pilot sequence of interest and tests its authenticity. The retrievability of authentic pilots is defined and formulated analytically. We also derive the analytical closed-form expression of system failure probability and accessibility in the regime of large-scale antenna arrays and short data packets. Interestingly, we find that four trade-offs exist: retrievability-latency, retrievability-accessibility, reliability-latency and reliability-accessibility. Simulation results show the security advantage of our proposed theory in grant-free URLLC system.
