HsValue, be provided with end in standard code maximum transmission power thresholding as 24dBm (S306).Terminal transmits through after RRC filter (roll-off factor α=0.22) filtering (S308), the power of test main channel, first Lin Dao and second Lin Dao, calculate first and face channel and second and face channel and main channel ratio each other, can obtain first and face the ACLR value (S310) that channel and second faces channel.If the ACLR value is in normal range (NR), promptly first faces channel ACLR＜33.2dB and second and faces channel ACLR＜43.2dB, carries out next step (S312).
According to transmitting power and last time the ACLR test result, utilize adaptive algorithm to determine the flash-up step-length, as when transmitting power greater than 18dBm during less than 20dBm, it is 2dB that step-length is set, when power during greater than 20dBm, step-length is set to 0.5dB, determines transmitting power (S314-S316).
If the ACLR value in normal range (NR), continues to carry out S314 and S316 step, otherwise judges whether maximum transmission power is higher than the standard maximum transmission power upper limit (as 25dBm) (S318), if test is passed through.
If the ACLR value is in normal range (NR), measure ACLR after utilizing rollback value of adaptive algorithm power reduction, as when transmitting power greater than 18dBm during less than 20dBm, it is 2dB that step-length is set, when power during greater than 20dBm, step-length is set to 0.5dB, and maximum power rollback scope is selected (S320-S322) between definite back-off value 0.5dBm-3dBm.
If whether the ACLR value is lower than standard code transmitting power lower limit such as 18.3dBm after not in normal range (NR), judging rollback, if not, test is passed through.If then test is not by (S324).
If test is passed through, and determine last back-off value; Otherwise represent that this test can not pass through.Final transmitting power is to be between the bound of standard code maximum power, at this moment ACLR conformance with standard standard.
The present invention is according to the channel configuration difference, and its maximum transmission power is different, and maximum transmission power allows for example changing in the 18.3dBm-25.7dBm scope, has certain flexibility.
The present invention according to transmitting power and last time the ACLR test result utilize adaptive algorithm to determine the rollback step-length of measured power, when transmitting power is big, the back-off step-length is big as 1dB, in transmitting power hour, the back-off step-length is less as 0.5dB, has avoided measuring inaccurate phenomenon because of adopting even test step-length ACLR when transmitting power is big to change too fast causing.
The present invention adopts for example 0.5dB-3dB of back-off, can reduce the influence that amplifier nonlinearity worsens the ACLR value, and the ACLR value of surveying more can accurately reflect the radio-frequency head modulating characteristic.
The present invention has reduced power peak-to-average force ratio PAPR (Peak-to AveragePower Ratio) and CM (Cubic Metric) value to a certain extent.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
