Uplink Performance Improvement by Decoupling Uplink/Downlink Access in HetNets

In dense and heterogeneous cellular networks (HetNets), significant imbalance between uplink (UL) and downlink (DL) transmissions may happen in regard to signal-to-interference-and-noise ratio and traffic load. Under this circumstance, decoupled UL/DL access (DUDA) is proposed for HetNets for improving system performance. In this paper, we theoretically investigate UL performance improvement broug...
