Contents I. Introduction
Fifth Generation (5G) has been deployed in many countries around the world with outstanding superiorities in comparison with 4G such as high bit rates, low latency, high capacity, and many new services [1]. However, with the rapid development of technology, beyond 5G such as 6G become the most attractive wireless network with the research community recently. Although this network generation is being researched in terms of academic and commercial. Compared with 5G networks, 6G wireless networks have requirements for providing high-speed experience services, saving and using smart energy to meet services such as IoT, smart cities, and autonomous ports. . . [2]. Many cooperative radio technology technologies have been researched and gradually put into practice, including energy harvesting (EH) [3] and intelligent reflecting surface (IRS) [4].
