虽然新的移动通信系统LTE提供了更高的带宽,更好的频谱利用率,但是无线网络提供给用户的带宽始终有限的,为了满足不断增长的用户需求,就需要合理规划和利用无线资源。无线资源调度的不合理将会影响用户的网络体验和通信质量,因此资源调度算法是LTE系统中必不可少的技术之一。 Although the new mobile communication system LTE provides higher bandwidth and better spectrum utilization, the bandwidth provided by wireless networks to users is always limited. In order to meet the ever-increasing demand of users, radio resources need to be planned and utilized reasonably. Radio resource scheduling unreasonable will affect the user’s network experience and communication quality, resource scheduling algorithm is one of the indispensable technologies in the LTE system.
