摘要： Method and apparatus for adjusting the transmission power of base stations in simultaneous communication with a mobile station. The methods described provide for the transmission power of the base stations to be aligned. In the first exemplary embodiment, the transmitters are attached to a separate control unit through communication links. The control unit then derives the most likely command stream and send that to the base stations. In the second exemplary embodiment, the control unit periodically receives the final or average transmit level in a period and an aggregate quality measure for the feedback during a period from each of the transmitters. The control unit determines the aligned power level and transmits a message indicative of the aligned power level to the transmitters. In the third exemplary embodiment, the transmitters send the control unit a message indicative of the transmit power of transmissions to the receiver. The control unit determines the aligned transmit power based on the current transmit power.

摘要翻译： 用于调整与移动台同时通信的基站的发射功率的方法和装置。 所描述的方法提供了要对准的基站的发射功率。 在第一示例性实施例中，发射机通过通信链路附接到单独的控制单元。 控制单元然后导出最可能的命令流并将其发送到基站。 在第二示例性实施例中，控制单元在每个发射机的周期期间周期性地接收一段时间内的最终或平均发送电平以及用于反馈的总体质量度量。 控制单元确定对准的功率电平，并将指示对准的功率电平的消息发送到发射机。 在第三示例性实施例中，发射机向控制单元发送指示传输到接收机的传输功率的消息。 控制单元基于当前发射功率确定对准的发射功率。
