摘要： Provided is a transmission power control device and method calculating a compensated estimated signal-to-interference ratio (SIR) by subtracting an SIR margin according to change in the state of a receiving channel when measuring an estimated SIR of a reception signal at a receiving end, and determining an increase or decrease in transmission power according to a difference between the compensated estimated SIR and a target SIR, thereby providing a variable SIR margin threshold for TPC bit decision and preventing unnecessary cyclic redundancy check (CRC) errors and untimely change of the target SIR. Therefore, it is possible to efficiently reduce transmission and reception power consumption due to slow update of an existing target SIR, and to prevent a cyclic redundancy check (CRC) error caused by the untimely change of the target SIR.
摘要翻译：提供了一种发送功率控制装置和方法，当测量接收端的接收信号的估计SIR时，根据接收信道的状态的变化减去SIR余量来计算补偿估计信号干扰比（SIR），并且根据补偿估计SIR与目标SIR之间的差来确定发送功率的增加或减少，从而为TPC比特决定提供可变的SIR余量阈值，并防止不必要的循环冗余校验（CRC）错误和不及时改变目标SIR。因此，可以有效地降低由于现有目标SIR的较慢更新所引起的发送和接收功率消耗，并且防止由于目标SIR的不及时改变引起的循环冗余校验（CRC）错误。
