Abstract

The invention discloses a power control method and device. The power control method comprises the following steps: confirming resource utilization rate corresponding to a first communication frequencyband and at least one second communication frequency band for the target area respectively; calculating and obtaining the transmission power difference between the at least one second communication frequency band and the first communication frequency band at least based on the resource utilization rate corresponding to each communication frequency band and the bandwidth of each communication frequency band; and adjusting the transmission power of the at least one second communication frequency band at least based on the transmission power difference to obtain the adjusted transmission power of the at least one second communication frequency band.

Description

technical field [0001] The present invention relates to signal transmission technology in the communication field, in particular to a power control method and device. Background technique [0002] Considering the rapid improvement of the utilization rate of TD-LTE network resources, in the service area of ​​mobile communication, it is possible to deploy supplementary communication frequency points in the main communication frequency band or main communication frequency points for load sharing. In the prior art, when the deployment scheme of supplementary communication frequency band + main communication frequency band is usually adopted, the transmit power of the two communication frequency bands (or frequency points) is set to the same power, so as to maximize the spectrum efficiency. However, the above-mentioned setting method cannot guarantee flexible adjustment to the transmit power of the supplementary frequency points, and thus cannot guarantee to reduce the impact on ...
