    • PROBLEM TO BE SOLVED: To solve the disadvantage caused by a sudden increase in power transmitted from E-DPDCH transmitted by a mobile station UE in a mobile communication system of an EUL system.
      SOLUTION: This transmission rate control method includes: a step in which a radio base station NodeB determines a maximum granted value that is notified to the mobile station UE, in accordance with the Happy bit notified from the mobile station UE; a step in which the radio base station NodeB calculates as an allowable value to be notified to the mobile station UE, a granted value not more than the maximum granted value; a step in which the radio base station NodeB notifies the calculated granted value to the mobile station UE, by using a transmission rate control channel; and a step in which the mobile station UE transmits the uplink user data, at a transmission rate corresponding to the notified granted value.

    • 解决的问题:解决由EUL系统的移动通信系统中由移动台UE发送的E-DPDCH发送的功率的突然增加所引起的缺点。 解决方案:该传输速率控制方法包括:根据从移动台UE通知的Happy位,无线基站NodeB确定通知移动台UE的最大允许值的步骤; 无线基站NodeB计算作为要通知移动台UE的容许值的步骤,不超过最大允许值的许可值; 通过使用传输速率控制信道,无线基站NodeB向移动台UE通知计算出的许可值的步骤; 以及移动台UE以对应于所通知的许可值的传输速率发送上行用户数据的步骤。 版权所有(C)2009,JPO&INPIT
