Abstract After the deployment of 5th generation (5G), beyond 5G (B5G) and 6th (6G) communication grabs critical attention academia researchers. In ongoing cellular generation, selected radio spectrum (i.e., millimeter waves [mm‐Wave]) is unable to achieve required data rates. Future generations need more rate link reliability serve emerging intelligent applications B5G 6G (e.g., autonomous driving, virtual reality, etc.). To handle these limitations researchers are working on key factors...
