LTE macro-micro co-networking can help to improve the coverage in smal local areas and increase the network capacity, however different frequency using strategies wil result in different network performance. Firstly the pros and cons of macro-micro co-networking with the same frequency and different frequencies are analyzed respectively. Then the simulation and test results of both are introduced and compared. Finaly some suggestions are given on frequency using strategy of macro-macro co-networking. The conclusions have some reference value tothe current LTE network construction.
