Problems solved by technology
When the channel condition changes, the adjustment of the transmit power in the prior art does not consider the channel environment, which may lead to a waste of system gain due to excessively high transmit power, and at the same time cause interference to other transmission systems, or even cause service failure due to too low transmit power

The embodiment of the invention discloses a method and a device for adjusting transmission power. The method comprises the following steps of: acquiring transmission power configuration information, wherein the transmission power configuration information comprises a transmission power lower limit and a transmission power upper limit; acquiring modulation mode configuration information, wherein the modulation mode configuration information comprises a lower limit modulation mode and an upper limit modulation mode; acquiring the current channel information; calculating according to the currentchannel information, the transmission power configuration information and the modulation mode configuration information to obtain first transmission power and a first modulation mode; and transmitting a control signal according to the first transmission power and the first modulation mode. In the process of changing the channel conditions, the channel information, the transmission power lower limit, the transmission power upper limit, the lower limit modulation mode and the upper limit modulation mode are simultaneously considered to obtain the optimized transmission power and modulation mode; therefore, the transmission power is improved, and conditions of service blockage due to over-low transmission power, system gain waste due to over-high transmission power and the like are effectively avoided.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for adjusting transmission power. Background technique [0002] Optical fiber transmission is very mature both in terms of technology and network application. However, due to restrictions such as terrain and topography, wireless transmission is required in many places. In the case of large bandwidth requirements, microwave transmission is usually used. At present, in the applications of the base station backhaul transmission of the mobile cellular system, the network of the metropolitan area network of the transmission network, the digital relay transmission network of the radio and television, the private network (such as electric power, the army, etc.) Wider range of applications. [0003] In the microwave transmission communication system, the commonly used frequency bands are 1.4GHz~2.7GHz, 3GHz~11GHz, and 23GHz~55GHz, etc., the channel ban...
