“…Type (i) can be further divided into Dynamic Spectrum Sharing (DSS), Licensed Shared Access (LSA), and Spectrum Access System (SAS). DSS has been envisioned as a seamless global transition towards universal 5G deployment, and it is based on highlevel scheduling algorithms between 4G and 5G [14].

As the services and requirements of next-generation wireless networks become increasingly diversified, it is estimated that the current frequency bands of mobile network operators (MNOs) will be unable to cope with the immensity of anticipated demands. Due to spectrum scarcity, there has been a growing trend among stakeholders toward identifying practical solutions to make the most productive use of the exclusively allocated bands on a shared basis through spectrum sharing mechanisms. However, due to the technical complexities of these mechanisms, their design presents challenges, as it requires coordination among multiple entities. To address this challenge, in this paper, we begin with a detailed review of the recent literature on spectrum sharing methods, classifying them on the basis of their operational frequency regime-that is, whether they are implemented to operate in licensed bands (e.g., licensed shared access (LSA), spectrum access system (SAS), and dynamic spectrum sharing (DSS)) or unlicensed bands (e.g., LTE-unlicensed (LTE-U), licensed assisted access (LAA), MulteFire, and new radio-unlicensed (NR-U)). Then, in order to narrow the gap between the standardization and vendor-specific implementations, we provide a detailed review of the potential implementation scenarios and necessary amendments to legacy cellular networks from the perspective of telecommunication vendors and regulatory bodies. Next, we analyze applications of artificial intelligence (AI) and machine learning (ML) techniques for facilitating spectrum sharing mechanisms and leveraging the full potential of autonomous sharing scenarios. Finally, we conclude the paper by presenting open research challenges, which aim to provide insights into prospective research endeavors.

“…For example, Qualcomm introduced the Snapdragon X55 modem [110] to provide coverage for different generations from 2G to 5G. This modem also has the ability to provide DSS technology to facilitate coexistence Case B: SSB with 30 kHz at (4,5,6,7), (8,9,10,11), (16,17,18,19), and (20,21,22,23) symbols for 𝑓 ≤ 3 𝐺𝐻𝑧 Case C: SSB with 30 kHz at (2,3,4,5), (8,9,10,11), (16,17,18,19), and (22,23,24,25) symbols for 𝑓 ≤ 3 𝐺𝐻𝑧…”
