　　在有限反馈系统中，针对用户端向基站反馈完整的信道状态信息对上行链路传输能力要求较高、设备实现较为复杂的问题，给出一种基于码本的最大化 SLNR 及 SFR 的 PF 调度算法。该算法通过码本量化预编码矩阵，基站仅需用户端反馈码本编号即可获得预编码矩阵，从而大大降低了信息反馈量。仿真结果表明，算法保证了系统和边缘用户性能，但是，作为降低反馈量的代价，与引入码本前相比，算法性能略微下降。

Aiming at the high requirement of uplink transmit and the complexity of device implemention in complete feedback of channel state information, a PF scheduling algorithm maximizing SLNR and SFR based on code book is proposed. The algorithm could greatly reduce the feedback by quantized precoding matrix based on maximizing SLNR and SFR. Simulations results show that this algorithm could ensure the subscriber’s fairness, while slightly reduce the algorithm’s performance as a result of debasing feedback as compared to no-codebook condition.
