摘要： The invention relates to a method of globally balancing the transmit power in a cellular radio system with tight reuse of frequencies, to a central controller node, and to an access point that in combination with conventional power control schemes balances the downlink transmission power on reused frequencies in order to balance co-channel interference in a multi-cell environment. The power balancing scheme dynamically assigns a token to or takes a token away from an individual reused radio channel based on quality of, or based on transmission power in the channel. A token, if taken away from the channel, inhibits conventional power control thereby freezing the transmission power in the channel on its current power level. A token, if assigned or re-assigned to channel, re-assumes conventional power control thereby allowing dynamic variation of the transmission power in the channel in accordance with the conventional power control .
摘要翻译：本发明涉及一种将蜂窝无线电系统中的发射功率与频率的紧密重用，中央控制器节点以及接入点全局平衡的方法，该接入点结合常规功率控制方案，将重新使用频率上的下行链路传输功率平衡以平衡多小区环境中的同信道干扰。功率平衡方案基于质量或基于信道中的传输功率动态地将令牌分配给令牌或从令牌远离个体重用无线电信道。令牌，如果从通道中取走，则禁止传统的功率控制，从而冻结通道当前功率水平的发射功率。令牌，如果被分配或重新分配给信道，则重新采用传统的功率控制，从而允许根据常规功率控制在信道中的发射功率的动态变化。
