The invention belongs to the technical field of wireless communication, and particularly relates to a high-energy-efficiency networking method for realizing adaptive large-scale URLLC. The method comprises the following steps: constructing a communication system model, and distributing available channels to corresponding users according to the proportion that the users have URLLC requirements and do not have the URLLC requirements; modeling small-scale fading and calculating a small-scale fading gain; performing channel estimation and multi-user detection according to the communication system model and the small-scale fading gain to obtain a posterior signal-to-noise ratio of the user; calculating the upper bound of the time delay exceeding probability of the user according to the posterior signal-to-noise ratio of the user; adjusting the sending power and the number of available channels according to the upper bound of the time delay exceeding probability of the user so as to realize network recombination; t
