    • The present invention relates to a method and an enhanced uplink (UL) telecommunication system for power control. The system comprises at least one first radio network controller (RNC) (12) and at least one first base station (11), which enables wireless communication with at least one first user terminal (15). The power for an uplink Dedicated Physical Control Channel (DPCCH) in a first enhanced UL transport channel (E-DCH) is controlled. The control is made by the first base station (11) on the basis of a signal to interference ratio (SIR) target value sent by the first RNC (12). Thereby, the SIR real time value for the UL DPCCH is controlled towards the target value. The first user terminal (15) and the first base station (11) further calculate a power for at least an Enhanced Dedicated Physical Data Channel (E- DPDCH) in the first E-DCH, which power is defined as the sum of the DPCCH power and a power offset. The calculation is at least based on a power offset configuration and an absolute grant provided by the first base station (11), which grant at least set the maximum E-DPDCH power. The first user terminal (15) further transmits the uplink data traffic on the first E-DCH with the controlled DPCCH power and the calculated E-DPDCH power. What particularly characterises the present invention is that when the first base station (11) and the first user terminal (15) detects that the E-DPDCH absolute grant is reduced below or increased above a grant threshold, the base station (11) changes the SIR target value. Further, the first base station (11) and the first user terminal (15) compensates the change of the target value by recalculating at least the E-DPDCH power so that the power reflects both the changed DPCCH power resulting from the changed SIR target value and the improvement due to optimized channel estimation in case of changed SIR real time value.
    • 本发明涉及用于功率控制的方法和增强型上行链路(UL)电信系统。 该系统包括至少一个第一无线电网络控制器(RNC)(12)和至少一个第一基站(11),其能够与至少一个第一用户终端(15)进行无线通信。 控制第一增强型UL传输信道(E-DCH)中的上行链路专用物理控制信道(DPCCH)的功率。 基于由第一RNC(12)发送的信号干扰比(SIR)目标值,由第一基站(11)进行控制。 由此,针对目标值控制UL DPCCH的SIR实时值。 第一用户终端(15)和第一基站(11)还计算第一E-DCH中的至少一个增强型专用物理数据信道(E-DPDCH)的功率,该功率被定义为DPCCH的和 功率和功率偏移。 该计算至少基于功率偏移配置和由第一基站(11)提供的绝对授权,其允许至少设置最大E-DPDCH功率。 第一用户终端(15)还在具有受控DPCCH功率和所计算的E-DPDCH功率的第一E-DCH上进一步发送上行链路数据业务。 本发明的特征在于,当第一基站(11)和第一用户终端(15)检测到E-DPDCH绝对授权减少到低于或增加到高于授权阈值时,基站(11)改变 SIR目标值。 此外,第一基站(11)和第一用户终端(15)通过至少重新计算E-DPDCH功率来补偿目标值的变化,使得功率反映由改变的SIR目标值产生的改变的DPCCH功率 并且在SIR实时值改变的情况下由于优化的信道估计而改进。

    • The invention refers to a method for improved congestion control in a wireless mobile system where a high speed packet data access (HSDPA) between a node and a number of mobile stations (MS) have been established by dedicating a high speed physical downlink shared channel (HS-PDSCH) to all mobile stations (MS) and one associated dedicated channel (A-DPCH) per each mobile station (MS).
