The invention belongs to the technical field of communication, and particularly relates to a dynamic resource allocation method based on an intelligent reflector assisted uplink system. The invention relates to an intelligent reflector auxiliary communication system, a Lyapunov optimization theory framework, a drift and penalty algorithm and other knowledge. A scheme for dynamically selecting an intelligent reflecting surface is provided, and at the starting moment of each frame, a user can select a certain IRS to assist communication or select to directly communicate with a base station. Meanwhile, the long-term stability of the performance of the dynamic system and the long-term satisfaction of the constraint are researched. In addition, a fractional programming method based on Lagrangian dual transformation is adopted to iteratively optimize power distribution of users and phase shift of an intelligent reflecting surface. On the whole, the method has good convergence and effectiveness. Compared with other
