Abstract: The demand for mobile data in today’s society grows explosively,but the limited capacity of the resources severely affects the expansion and improvement of business capacity.Taking the imbalance in the occurrence of wireless data into account,increasing the deployment of small-area cells will undoubtedly become the effective approach.By exa-mining the method to reduce the overhead of the uplink and downlink reference signals and control signaling in small cells,this paper introduced a method to improve cell density by deploying small cells.Compared with the macro-cell deployments,this proposed method can effectively reduce the cost of small cells,and enhance the efficiency of resource usage.

Key words: Small cell,Macro cell,Subframe,Reference signal,Control signaling,UE,eNB
