无线电频谱是支持各种无线服务的宝贵资源。传统上，它是由固定的频率分配策略来管理的，该策略将频段分配给许可证持有人独家使用。动态频谱接入被认为是一种很有前途的方法，它允许新的无线系统在协商或机会的基础上动态访问或共享许可的频段，从而提高频谱利用率。
The radio spectrum is a precious resource that underpins various wireless services. It is traditionally regulated by a fixed frequency assignment policy, which allocates frequency bands to license holders for exclusive use. Dynamic spectrum access has been proposed as a promising approach to improve spectrum utilization by allowing new wireless systems to dynamically access or share the licensed band on a negotiated or an opportunistic basis.
