Abstract

To employ the network resources more effectively and flexibly, cloud radio access network (C-RAN) adopts centralized network construction and management. Since the new network characteristics, the self-healing is reliable distinguish compared with previous studies. This paper drives a solution for self-healing 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.
