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本质是非常动态的，部分原因是无线信道可能的快速变化，部分原因是广泛的用户应用和最近出现的移动应用的多样化要求。传统通信系统的架构和参数是基于所有预期通信场景的“最坏情况”静态设计的。在不考虑信道条件和用户需求的动态特性的情况下，当系统在改善的信道条件或减少的数据流量下运行时，静态设计方法常常导致通信资源的使用效率非常低。
