The nature of future broadband wireless communications is very dynamic, due partly to the possible fast variation of wireless channels, and partly to the wide range of user applications and diverse requirements from recent advent of mobile applications. Architecture and parameters of conventional communications systems are designed statically based on a "worst case" of all expected communications scenarios. Without considering the dynamic nature of channel conditions and user requirements, the static design approach often leads to a very inefficient usage of the communications resources when the system operates at improved channel conditions or reduced data traffic.

未来宽带无线通信的性质非常动态，部分是由于无线通道的快速变化，部分是由于最近移动应用程序出现的广泛用户应用程序和各种要求。常规通信系统的体系结构和参数是根据所有预期通信方案的“最坏情况”静态设计的。在不考虑渠道条件和用户需求的动态性质的情况下，静态设计方法通常会导致系统在改善的频道条件下运行或减少数据流量时，对通信资源的使用效率非常低。
