Abstract

The embodiment of the invention provides a power control method in a communication network, a base station, and a communication system. The power control method comprises: A, performing power distribution in the first dimensionality of the communication network in order to obtain a first power distribution result; B, determining whether the first power distribution result satisfies a stable condition, and ending the power control if yes or executing the step C if not; C, performing power distribution in the second dimensionality of the communication network in order to obtain a second power distribution result; and D, determining whether the second power distribution result satisfies the stable condition, and ending the power control if yes or executing the step A if not. The power control method, the base station, and the communication system achieve balance between interference and resource utilization efficiency.

Description

technical field [0001] The invention relates to the field of communication, in particular to a power control method in a communication network, a base station, and a communication system. Background technique [0002] The data growth in the communication network can be solved by deploying communication cells, and small cell (small cell, SC) deployment is one of the solutions. like figure 1 As shown, the distance between the small cells deployed in the early stage is relatively large, and the interference between the small cells can be ignored. However, existing small cell deployments are dense and random. from figure 1 It can be seen that a plurality of small cells with relatively close distances form a small cell group, and overlapping coverage areas exist among these small cell groups, which brings challenges to the management of cell interference. For dense small cell deployment, interference will become a bottleneck for improving throughput. The existing almost blan...
