    • PURPOSE: An uplink power control method and an uplink signal method using the same are provided to accurately control uplink transmission power by reflecting path loss for a plurality of reception points in an uplink CoMP(Coordinated Multi-Point) system. CONSTITUTION: UE(User Equipment) receives a downlink signal from transmission points(S510). The UE calculates path loss for each point(S520). The UE calculates PLE(Effective Path Loss) for uplink power control(S530). The UE calculates power for uplink transmission based on the calculated PLE(S540). The UE executes the uplink transmission through the calculated transmission power(S550). [Reference numerals] (AA) Start; (BB) End; (S510) Receiving downlink signaling; (S520) Calculating path loss for each point; (S530) Calculating effective path loss; (S540) Calculating uplink power control; (S550) Transmitting uplink;
    • 目的:提供上行链路功率控制方法和使用该上行链路功率控制方法的上行链路信号方法,以通过反映上行链路CoMP(协调多点)系统中的多个接收点的路径损耗来精确地控制上行链路发送功率。 构成:UE(用户设备)从传输点接收下行链路信号(S510)。 UE计算每个点的路径损耗(S520)。 UE计算上行链路功率控制的PLE(有效路径损耗)(S530)。 UE根据计算出的PLE计算上行链路传输的功率(S540)。 UE通过计算出的发送功率执行上行链路传输(S550)。 (附图标记)(AA)开始; (BB)结束; (S510)接收下行信令; (S520)计算每个点的路径损耗; (S530)计算有效路径损耗; (S540)计算上行链路功率控制; (S550)发送上行;
