5G is a mobile communication network that meets the development needs of future communication.Due to the use of higher frequencies
more base BS are needed
results in huge CAPEX and OPEX.RAN sharing will be an effective way to speed up the 5G commercial process and reduce costs and increase efficiency.The possibility of 5G RAN sharing by analyzing the scheme under SA/SA and SA/NSA architecture was explored
then a systematic theoretical basis for 5G RAN sharing and co-construction was given.
