Massive MIMO Technologies and Challenges towards 5G
Massive MIMO is widely recognized as an essential technology for 5G. Together with newly allocated spectrum (bandwidth) and network densification (small cells), it is expected to play a key role in coping with the ongoing explosion in data-traffic demand and services. Compared to 4G MIMO technologies, massive MIMO can offer large gains in cell spectral efficiency, which, in combination with sma...
متن کاملMassive MIMO 5G Cellular Networks: mm-wave vs. μ-wave Frequencies
Enhanced mobile broadband (eMBB) is one of the key use-cases for the development of the new standard 5G New Radio for the next generation of mobile wireless networks. Large-scale antenna arrays, a.k.a. Massive MIMO, the usage of carrier frequencies in the range 10-100 GHz, the so-called millimeter wave (mm-wave) band, and the network densification with the introduction of small-sized cells are ...
متن کامل5G small-cell networks leveraging optical technologies with mm-wave massive MIMO and MT-MAC protocols
Analog optical fronthaul for 5G network architectures is currently being promoted as a bandwidthand energy-efficient technology that can sustain the data-rate, latency and energy requirements of the emerging 5G era. This paper deals with a new optical fronthaul architecture that can effectively synergize optical transceiver, optical add/drop multiplexer and optical beamforming integrated photon...
متن کاملMassive MIMO and Millimeter Wave for 5G Wireless HetNet: Potentials and Challenges
There have been active research activities worldwide in developing the next-generation 5G wireless network. The 5G network is expected to support significantly large amount of mobile data traffic and huge number of wireless connections, achieve better costand energy-efficiency as well as quality of service (QoS) in terms of communication delay, reliability and security. To this end, the 5G wire...
متن کاملMassive MIMO for 5G
Massive MIMO is the currently most compelling sub-6 GHz physical-layer technology for future wireless access. The main concept is to use large antenna arrays at base stations to simultaneously serve many autonomous terminals, as illustrated in Figure 1. The rich and unique propagation signatures of the terminals are exploited with smart processing at the array to achieve superior capacity. Mass...
