    • Techniques for controlling transmit power are described. Due to link imbalance, a downlink (DL) serving cell may have the best downlink for a UE, and an uplink (UL) serving cell may have the best uplink for the UE. In one design of UL power control, the UE receives first and second UL TPC commands from the DL and UL serving cells, respectively, and adjusts its transmit power based on these UL TPC commands and in accordance with an OR-of -the-UPs rule. In one design of DL power control, the UE generates a DL TPC command based on received signal qualities of both the DL and UL serving cells. In another design, power control is performed independently for the DL and UL serving cells. This joint DL TPC command results from combining TPC commands based on respective received signal qualities of the DL and UL serving cells in accordance with an OR-of-the-UPS.
    • 描述了用于控制发射功率的技术。 由于链路不平衡,下行链路(DL)服务小区对于UE可以具有最佳下行链路,并且上行链路(UL)服务小区可以具有用于UE的最佳上行链路。 在UL功率控制的一种设计中,UE分别从DL和UL服务小区接收第一和第二UL TPC命令,并且基于这些UL TPC命令并且根据这些UL TPC命令的OR来调整其发射功率 规则。 在DL功率控制的一种设计中,UE基于DL和UL服务小区的接收信号质量生成DL TPC命令。 在另一种设计中,为DL和UL服务小区独立地执行功率控制。 该联合DL TPC命令根据基于UPS的OR的DL和UL服务小区的相应接收信号质量来组合TPC命令。
