Since the new network characteristics,the self-healing is reliable distinguish compared with previous studies. This paper drives a solution for selfhealing based on cooperative transmission and power adjustment under C-RAN self-healing management architecture. This compensation model with the aim to maximize the number of connected UEs and optimize power regulation is solved by Benders' decomposition algorithm. And through the simulation,this paper verifies the speediness and effectiveness of this scheme.展开更多

In order to compensate the outage cell autonomously, this paper drives a solution for COC. This method is based on coordinated multiple points(Co MP) transmission and tilt adjusting. Firstly, the paper takes the coordinated pattern and tilt as the optimization objects.
