An important aspect of 5G networks is the development Radio Access Network (RAN) slicing, a concept wherein virtualized infrastructure wireless subdivided into slices (or enterprises), tailored to fulfill specific use-cases. A key focus in this context efficient radio resource allocation meet various enterprises' service-level agreements (SLAs). In work, we introduce channel-aware and SLA-aware RAN slicing framework for massive multiple input output (MIMO) where extends incorporate spatial dimension available through beamforming. Essentially, same time-frequency block (RB) can be shared across users antennas. Notably, certain enterprises, particularly those operating critical infrastructure, necessitate dedicated RB allocation, denoted as private networks, ensure security. Conversely, some enterprises would allow sharing with others public network maintain performance while minimizing capital expenditure. Building upon understanding, proposed scheduler comprises scheduling schemes under both scenarios: different share set RBs, they require exclusivity allocated RBs. We validate efficacy our schedulers simulation by utilizing channel data collected from real-world MIMO testbed. Our assessments demonstrate that using approach lead up 60.9% reduction usage compared other approaches. Moreover, exhibit significantly enhanced operational efficiency, faster running time exhaustive greedy approaches meeting stringent sub-millisecond-level latency requirement.
