    • A method of power control in a wireless communications system wherein blocks are transmitted from a transmitter to a receiver via a wireless transmission channel. The method comprises comparing a target signal quality value with a received signal quality value and providing the results of the comparing step to the transmitter to adjust transmit power based on the comparing step. The target signal quality value is set by the following steps: determining an initial target value; determining if received blocks have been successfully decoded; identifying the received blocks as pass or fail blocks; when pass blocks are received, comparing the target signal quality value with the received signal quality value and decreasing the target value only if the target value is greater than the received signal quality value less a margin.
    • 一种在无线通信系统中的功率控制的方法,其中通过无线传输信道将块从发射机发射到接收机。 该方法包括:将目标信号质量值与接收到的信号质量值进行比较,并根据比较步骤向发射机提供比较步骤的结果以调整发射功率。 目标信号质量值由以下步骤设定:确定初始目标值; 确定接收的块是否已被成功解码; 将接收到的块识别为通过或失败块; 当接收到传递块时,仅当目标值大于接收信号质量值减去余量时,将目标信号质量值与接收到的信号质量值进行比较并降低目标值。

    • A method of power control in a wireless communication system, wherein blocks are transmitted from a transmitter to a receiver via a wireless transport channel. The method comprises comparing a target signal quality value with a received signal quality value and providing the results of the comparing step to the transmitter to adjust transmit power based on the comparing step. The target signal quality value is set by the following steps: determining an initial target value; detecting if a data block has been received; detecting if received blocks have been successfully decoded, and identifying the received blocks as pass or fail blocks; and decreasing the target value when pass blocks are received and increasing the target value when failed blocks are received subject to monitoring a period of inactivity on the transport channel in which no blocks, or only failed blocks are received and where the period of inactivity exceeds a threshold reducing a current target value to a value determined by the target value at commencement of the period of inactivity and possibly by the initial target value.
    • 一种在无线通信系统中进行功率控制的方法,其中通过无线传输信道将块从发射机发射到接收机。 该方法包括:将目标信号质量值与接收到的信号质量值进行比较,并根据比较步骤向发射机提供比较步骤的结果以调整发射功率。 目标信号质量值由以下步骤设定:确定初始目标值; 检测是否已经接收到数据块; 检测接收到的块是否已被成功解码,并将接收到的块识别为通过或失败块; 并且当接收到传递块时降低目标值,并且当接收到失败块时增加目标值,受监视在其中没有块或仅接收故障块的传输信道上的不活动周期以及不活动时段超过 阈值将当前目标值减小到在不活动时段开始时由目标值确定的值,并且可能将初始目标值减小。
