上行功率控制很重要,特别是TDD PTMP系统,最终可以实现基站接入的手机通信容量的增加。

GSM中基站对MS有少量的功率控制,当MS距离基站较近时基站会调节减小MS的发射功率,减少对相邻用户的干扰和对MS用户的辐射,当MS距离基站较远时,BTS会调节增加MS发射功率,目的是为了克服路径损耗! 这个实现方式有点像WCDMA中的远近效应,但是原理还是有区别的。
GSM手机用户最大发射功率为2W=33dBm WCDMA 语音用户为21dBm 数据用户24dBM

我想问,移动通信功率控制是两级功率控制吗?先根据蜂窝覆盖大小而限定BTS、MS最大输出功率;再根据MS位置收发信号情况再动态控制BTS、MS输出功率。还是就一级功率控制?根据MS位置收发信号情况而动态控制BTS、MS输出功率
