POWER CONTROL METHOD, APPARATUS AND SYSTEM
First Claim
1. A power control method, comprising:
- determining a transmit power P1 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 P1 is higher than or equal to a threshold value P2 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;
sending data on an interfering frequency of the first-standard communication system by using a power lower than transmit power P1, wherein the interfering frequency is a frequency that causes an interference to the second-standard communication system among hopping frequencies used by the service; and
sending data on a non-interfering frequency of the first-standard communication by using a power higher than the transmit power P1.

Abstract
The present invention discloses a power control method and apparatus. The power control method of the present invention includes: when a service runs in a first-standard communication system, determining a transmit power P1 of the first-standard communication system; determining that the transmit power P1 is higher than or equal to a threshold value P2 of power interference of the first-standard communication system to a second-standard communication system; use a power lower than P1 to send data on an interference frequency of the first-standard communication system. According to the power control method in the present invention, a signal transmit power of the interfering frequency of the first-standard communication system can be reduced when it is determined that the first-standard communication system will cause interference to the second-standard communication system, thereby reducing the interference of the first-standard communication system to the second-standard communication system.
