New radio technologies for the fifth generation of wireless system have been extensively studied globally. Specifically, air interface protocols for 5G radio access network will be standardized in coming years by 3GPP. All basic physical layer functions for the new radio system are currently under active development in 3GPP. Due to its crucial function in scheduled system, physical layer control channel...
Multi-Carrier (MC) modulation schemes like Orthogonal Frequency Division Multiplexing (OFDM) are highly sensitive to Phase Noise (PN). In the case of air interfaces operating in higher frequencies, e.g. the range between 6 and 100 GHz frequently called millimeter wave (mmWave), the PN generated by the local oscillators is even more accentuated. Alternative MC systems are being considered for future...
In the last years, the interest on millimeter wave communications increased due to the high potentiality foreseen to face the continuous growth of wireless communications capacity demand. One of the major drawback is represented by the limited coverage capacity. In order to cope with it, beamformers that generate beams with very narrow beams have been studied. Special attention has to be devoted to...
Millimeter-wave (mmWave) communication is envisioned to be a promising technology to cater for the continuous growth of wireless communication capacity demand. To compensate severe path loss for mmWave signals, mmWave system typically employs beamforming technique to achieve essential antenna gain. To provide services to multiple user equipment (UE), mmWave system needs to schedule UEs in both frequency...
Millimeter-wave (mmW) communication is envisioned to be a promising technology to cater for the continuous growth of backhaul link capacity demand. To compensate the severe path loss for mmW signals, the mmW backhaul link typically employs beam alignment between transmitter and receiver to achieve essential antenna gain. To reduce deployment cost and improve operational efficiency, it is desired to...
In the framework of the forthcoming 5G telecommunication system, the definition of realistic use cases and prototypes strongly connected to them is key in order to demonstrate how well emerging enabling technologies can fulfil the challenges introduced by the 5G Heterogeneous Network (HetNet) architecture. This paper shows how millimeter wave (mmWave) technologies can be properly assessed by selecting...
This paper studies the physical layer performance of a lean carrier with reduced reference symbols and reduced control channel overhead as a possible candidate for a new 5G air interface. Specifically, we will show that, with minor modifications and optimizations, competitive link level performance can be achieved even in extreme use case scenarios using synchronization and channel estimation algorithms...
This paper presents the main advantages and challenges that the introduction of millimeter-wave mobile access brings to the forthcoming 5G system architecture, focusing on the expected impact of that technology on standards and regulation bodies. The EU-funded project MiWaveS is taken as a concrete example for the standardization impact.
