Abstract

一种用于在用户终端的功率控制设备处控制至少一个分量载波上的多个发射信道上的发射功率的方法，所述方法包括步骤：针对所述至少一个分量载波中的每一个，分别计算多个功率值，所述多个功率值中的每一个一一对应于所述多个发射信道中的每一个；针对所述至少一个分量载波中的每一个，将对应的所述多个功率值求和，得到相应分量载波的功率值；改变所述多个功率值中至少一个的大小，使所述相应分量载波的功率值不大于分量载波的最大功率值限制。利用本发明的技术方案，补偿了LTE-A系统中的路径损耗差并确保了公平的跨CC调度，同时可以限制多个CC之间的发射功率差。并且仅需较少的计算量，用户能够灵活地进行联合调度。
