  In this paper, the fundamental throughput limits and extremums of the
invariant criteria of energy, power and spectral efficiency of the physical
layer (PHY) and medium access control (MAC) sublayer are proved. The invariant
criteria are constructed relying on Shannon m-ary digital channel capacity
which a rich palette of the technically interpreted physical and control
parameters consider. Therefore, the invariant criteria as very suitable for
research and design of the fifth generation (5G) communications extremely
performance problems are found. The smart distributed control techniques which
able implements on-the-fly the limits close and invariant criterion
optimization or trade-off is proposed. Such smart control techniques represent
a key disruptive technology meet the 5G and Beyond 5G network challenges.
