| Abstract: | The concept of "Green Communications" in broadband mobile soft real-time communication is discussed. The problems of how soft real-time service can save energy with delay and how to use threshold to have a balance between delay and energy are addressed. A power control algorithm, which is applicable to soft real-time service model, is introduced to optimize the power consumption of base stations. |
