Classification: CPC H | IPC H

Claim 1:
2. The method according to claim 1, wherein the determining, by the terminal device and based on the second offset and a smaller value between (1) a sum of the first offset and a maximum transmit power of the terminal device allowed by a first cell and (2) a maximum radio frequency output power that corresponds to the first power class and that is of the terminal device, a compensation amount of the first power class comprises:
determining, by the terminal device, the compensation amount of the first power class based on the following formula (1):

Pcompensation=Max(PEMAX−min(PEMAX+Poffset,Ppowerclass)−Qoffsettemp,0)(dB)  (1), wherein:

Pcompensation in the formula (1) represents the compensation amount of the first power class, PEMAX is the maximum transmit power of the terminal device allowed by the first cell, Poffset represents the first offset, Qoffsettemp represents the second offset, and Ppowerclass is the maximum radio frequency output power that corresponds to the first power class and that is of the terminal device.
