This paper focuses on the power allocation scheme for delay-constrained communication with delay requirements and time-varying channels. We formulate the effective capacity of the multi-user system for time-varying channel and propose the multiuser power allocation scheme (MPAS) based on effective capacity. Simulation results show that MPAS achieves 10%~20% effective capacity gain over the water-filling algorithm aimed at throughput maximization as well as the suboptimum power allocation algorithm.
