Abstract	With the rapid development of wireless personal communications, demand for higher rates and bandwidth becomes more and more significant. In order to satisfy the need, network providers tried to deploy more and more access points such as the RRHs, which can effectively increase spectrum efficiency and ensure reliable QoS to users. In fact, demand for resources in uplink and downlink is not equal in many of the services, such as online movie, downloading, etc. So the separation of uplink and downlink is developed, which allows the heavy traffic for downlink can be served by RRHs and the light one for uplink can be directly served by traditional micro/macro cell. Traditional research of the heterogeneous networks of LTE-Advanced mainly focus on system performance. But in this paper, we studied the effect of the separation from an energy efficient point of view under the evaluation of the LTE-Advanced system level simulation. The design of signaling to implement the separation is firstly raised. The cost and performance of the separation are also evaluated and fully analyzed.
