Fronthaul design for mmWave massive MIMO

摘要: Abstract This chapter discusses the fronthaul design for a millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO)-based heterogeneous network (HetNet). The dense small-cell deployment requires cost-effective with high capacity to accommodate 1000-fold increase of cellular 5G. Against this background, mmWave MIMO-based mesh has been attracting increasing interest. Compared existing solutions working at low-frequency bands, is very compatible ultradense small cells because link can be short (typically 50–200 m) mitigate path loss signals and guarantee line-of-sight link. Moreover, by leveraging emerging MIMO technique, we easily realize topology facilitate installation reduce cost. Additionally, beamforming techniques make more flexible intelligent. will present survey first, which followed market requirement future 5G HetNet. More importantly, concept network, where some issues including antenna techniques, design, duplexing protocol, in-band fronthaul, so on, discussed in detail.
