TLDR
A symmetric physical layer design with OFDM is proposed for all link types, including uplink, downlink, device-to-device, and backhaul, and a scalable OFDM waveform is proposed to handle the wide range of carrier frequencies and deployments.Abstract:
The standardization of the next generation 5G radio access technology has just started in 3GPP with the ambition of making it commercially available by 2020. There are a number of features that are unique for 5G radio access compared to the previous generations such as a wide range of carrier frequencies and deployment options, diverse use cases with very different user requirements, small-size base stations, self-backhaul, massive MIMO, and large channel bandwidths. In this article, we propose a flexible physical layer for the NR to meet the 5G requirements. A symmetric physical layer design with OFDM is proposed for all link types, including uplink, downlink, device-to-device, and backhaul. A scalable OFDM waveform is proposed to handle the wide range of carrier frequencies and deployments.read more

TL;DR: An analysis of several different oscillators, starting with the common class-B architecture and arriving to the proposed class-C design, shows that the latter exhibits a figure-of-merit (FoM) that is closest to the ideal FoM allowed by the integration technology.
The effects of phase noise in COFDM
TL;DR: In this article, it is shown that the amounts of these effects can be deduced from the spectrum of the phase noise using a pair of weighting functions, which simplifies the process of computation; it also makes it easier to visualize the consequences of any modifications to the phase-noise spectrum.

TL;DR: A closed solution for optimum window coefficients suited to this scenario is derived and can mitigate the joint effect of additive noise and intercarrier interference among subcarriers caused by the carrier frequency offset.
