This chapter describes in detail the DUDe technique. First, Section 9.2 goes through the main challenges HetNets must face in terms of radio planning and interference management, and reviews the potential solutions to address these problems. Thereupon, decoupling UL and DL is recognised as a new technique that can effectively improve the HetNet performance, as shown in Section 9.4, and also can impact positively the performance of other radio access technologies, such as Carrier Aggregation (CA), Coordinated Multipoint transmission and reception (CoMP) or millimetre wave (Section 9.5). The enabling radio access network architectures are discussed in Section 9.6 and higher layer opportunities and challenges are addressed in Section 9.7.
