DOI: 10.1109/tvt.2017.2653799
Abstract: 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… read more here.
