Abstract EN
Heterogeneous networks (HetNets) can increase network capacitythrough complementing the macro-base-station with low-power nodes, in response to the ongoing exponential growth in datatraffic demand.
While, unprecedented challenges exist in theplanning, optimization, and maintenance in HetNets, especially activities such as cell outage detection and mitigation arelabor-intensive and costly.
One potential solution to address theseissues is to introduce the extensively attracted self-organizingnetwork (SON).
This paper is mainly devoted to cell outage detectionand compensation methods in two-tier HetNets where macrocell andpicocells are coexisted.
A K-nearest neighbor (KNN) classificationalgorithm is employed to detect the cell outage automatically.
Consider the breakdown picocell can reload its degraded service tothe overlapped macrocell via vertical handover; only the breakdownmacrocell executes the performance compensation.
Power adjustment oneach resource block is carried out via Lagrange optimizing algorithmto compensate the breakdown cell.
Through intensive numericalexperiments, with the help of our proposal, the outage cells can besuccessfully detected and performance gain for the outage macrocellcan reach 91.4% with α=1/3.
