Accounting for time-varying channel fading and dynamic traffic arrival, a stochastic optimization issue is formulated, which aims to balance the queue delay of users and maximize the network total throughput. Based on Lyapunov optimization method, the closed-form optimal solution of the stochastic optimization issue is derived, and a low-complexity optimal delay equilibrium and power control method is proposed. The method is compared with a NOMA scheme using a non-optimal resource management method and a Time Division Multiple Access (TDMA) scheme with an optimal resource management method. Simulation results show that the proposed method can significantly improve network performance.
