Claim Text:
1. A method for evaluating power measurement accuracy of signal in a carrier aggregation, the method comprising: transferring a first indication to a front end for indicating a first gain mode is used for a first path and a second gain mode is used for a second path; wherein the first path and the second path are two paths of carrier aggregation of the front end, and the first path and the second path have a same signal transferring direction; receiving a first calibration signal via the first path in the first gain mode of the first path and the second gain mode of the second path; obtaining an amplitude of the first calibration signal; transferring a second indication to the front end for changing the second gain mode to a fourth gain mode for the second path; receiving a second calibration signal via the first path in a third gain mode of the first path and the fourth gain mode of the second path; and obtaining an amplitude of the second calibration signal, wherein the amplitude of the first calibration signal and the amplitude of the second calibration signal are used for evaluating power measurement accuracy; wherein the second gain mode is different from the fourth gain mode, and, the third gain mode is identical to the first gain mode, or the fourth mode.
