“…SAS is an emerging SS model that is currently gaining attention [70], [73], [76], [88], [91]- [93]. In the USA, SAS can be used by operators to access the 3.5 GHz military radar band for commercial use.…”

“…However, sharing activities have been observed between mobile operators in recent years mainly due to the limited infrastructure. With SS, capacity demands have increased substantially despite the decrement in average revenue per user [70]. Another advantage of infrastructure sharing is the multitude of costs related to network deployment and maintenance, which leads to low capital expenditure.…”

“…Several SS licenses can be applied for 5G use, such as exclusive use (individual licenses), license-exempt rules (unlicensed or commons), LSA and authorised shared access, citizen broadband radio service with SAS, pluralistic licensing and Licensed Assisted Access (LAA) co-primary shared access. An overview of these license schemes was presented by [70], with legal regulations (in USA, Europe and elsewhere) and trial activities for SS schemes (LSA, LAA and SAS) as well as the characteristics of SS from inter-operator and virtualised network architecture perspective.…”

“…Although SS is beneficial, the challenges of its adoption must be clearly addressed by operators and competitors to ensure benefits to all parties involved. Furqan et al [70] presented an overview of SS schemes considered for 5G networks and discussed SS techniques, legal regulations and trial activities in detail. Furthermore, a basis of spectrum management for SS was discussed.…”

“…SS classification can be divided into three parts: according to the spectrum access behaviour (cooperative or non-cooperative), network architecture (centralised or decentralised) and spectrum access methods (overlay or underlay) [72]. Several of the challenges were addressed by [70]. These challenges included spectrum management and spectrum assignment, metrics to quantify spectrum usage, interference coexistence and management, security and enforcement, protocols and standards and regulatory, policy and economic problems.…”

The explosive popularity of small-cell and Internet of Everything devices has tremendously increased traffic loads. This increase has revolutionised the current network into 5G technology, which demands increased capacity, high data rate and ultra-low latency. Two of the research focus areas for meeting these demands are exploring the spectrum resource and maximising the utilisation of its bands. However, the scarcity of the spectrum resource creates a serious challenge in achieving an efficient management scheme. This work aims to conduct an in-depth survey on recent spectrum sharing (SS) technologies towards 5G development and recent 5G-enabling technologies. SS techniques are classified, and SS surveys and related studies on SS techniques relevant to 5G networks are reviewed. The surveys and studies are categorised into one of the main SS techniques on the basis of network architecture, spectrum allocation behaviour and spectrum access method. Moreover, a detailed survey on cognitive radio (CR) technology in SS related to 5G implementation is performed. For a complete survey, discussions are conducted on the issues and challenges in the current implementation of SS and CR, and the means to support efficient 5G advancement are provided.
