摘要：
This paper deals with Multiple Input and Multiple Output (MIMO) based Discontinuous Transmission (DTX) algorithms for cloud based Radio Access Network (RAN) systems. While DTX and MIMO have been individually investigated to improve the Energy Efficiency of base-stations, joint optimization of MIMO based DTX algorithms is still an open issue. In this paper, we first investigate practical limits and performance of joint use of MIMO and DTX using models for remote radio head (RRH). Then, we illustrate and identify scenarios in which MIMO and DTX are jointly beneficial for improving the energy performance of cloud based radio access network.
