“…Device-to-Device (D2D) technology is also used to reduce the system complexity, provide security from malicious users, and provide better reliability [ 20 , 21 , 22 , 23 , 24 ]. The bandwidth of the cellular network can be improved by using carrier aggregation (CA) techniques [ 25 , 26 , 27 , 28 , 29 ]. The opportunities and future challenges of massive MIMO in 5G and beyond are discussed in [ 29 ].…”

Fifth generation (5G) is a recent wireless communication technology in mobile networks. The key parameters of 5G are enhanced coverage, ultra reliable low latency, high data rates, massive connectivity and better support to mobility. Enhanced coverage is one of the major issues in the 5G and beyond 5G networks, which will be affecting the overall system performance and end user experience. The increasing number of base stations may increase the coverage but it leads to interference between the cell edge users, which in turn impacts the coverage. Therefore, enhanced coverage is one of the future challenging issues in cellular networks. In this survey, coverage enhancement techniques are explored to improve the overall system performance, throughput, coverage capacity, spectral efficiency, outage probability, data rates, and latency. The main aim of this article is to highlight the recent developments and deployments made towards the enhanced network coverage and to discuss its future research challenges.
