Patent ID: 8694047

Claim:
A power control method, comprising: determining a transmit power P 1 of a base station of a first-standard communication system when a service runs in the first-standard communication system; determining that the transmit power P 1 is higher than or equal to a threshold value P 2 of a power interference of the first-standard communication system to a second-standard communication system, wherein the first-standard communication system is different from the second-standard communication system; when (P max −P 1 )×n 1 >(P 1 −P 2 )×n 2 +P offset is determined, wherein the n 1 is a number of non-interfering frequencies, the n 2 is a number of interfering frequencies, the P offset is an offset of the compensated power, the P max is a maximum transmit power of a cell of the first-standard communication system where the service is ran, sending data on an interfering frequency of the first-standard communication system by using a power lower than transmit power P 1 , wherein the interfering frequency is a frequency that causes an interference to the second-standard communication system among hopping frequencies used by the service, comprising: sending the data on the interfering frequency by using a power of the threshold value P 2 of the interference; and sending data on a non-interfering frequency of the first-standard communication by using a power higher than the transmit power P 1 ; wherein the power for sending data on the interfering frequency is determined according to a relationship between a lost power on the interfering frequency when the power for sending data on the interfering frequency is reduced to the P 2 and a compensated power on the non-interfering frequency when the power for sending data on the non-interfering frequency is increased to the P max .
