9. A non-transitory computer-readable medium containing instructions for providing hybrid functional splits for a system which, when executed, cause the system to perform steps comprising:
defining, for a system having a Radio Unit (RU) and a Distributed Unit (DU) a Centralized Unit (CU) and an interface protocol between the RU to the DU and to the CU, a plurality of split options for balancing computer power and spectral efficiency, the plurality of split options including
a split option 6 in which users are served by a single cell and
a split option 7.x in which users are served by multi-cell joint processing; and
running, by at least one of the DU or CU, at least one cellular protocol stack software (SW).
