5G New Radio User Equipment Power Modelling and Potential Energy Savings

Currently the 3rd generation partnership project (3GPP) is studying how user equipment power saving can be achieved for the upcoming fifth generation New Radio technology. To accomplish this objective a power model has been developed for evaluation of schemes related to Radio Resource Control (RRC) Connected mode, Radio Resource Management, and efficient state transitions among other topics. In this work, we examine the RRC Connected mode using a single-user numerical simulation tool and the proposed user equipment power model. We demonstrate that the use of short Discontinuous Reception (DRX) can provide 30% energy saving and 70% latency reduction as compared to the 3GPP baseline with regular DRX. Furthermore, the simulation results of two release 15 schemes and two proposed schemes for release 16 may further reduce the energy consumption 15% at the cost of a small latency increase and potentially lower overall network performance.

© 1963-2012 IEEE. This article presents a packaged SiGe BiCMOS reflectometer for 0.01-26-GHz two-port vector network analyzers (VNAs). The reflectometer chip is composed of a resistive bridge coupler and two wideband heterodyne receivers for coherent magnitude and phase detection. In addition, a high-linearity receiver channel is designed to accommodate 20 ...

Protecting photonic quantum states using topology

  • Blanco-Redondo A.

The use of topology to protect quantum information is well-known to the condensed-matter community and, indeed, topological quantum computing is a bursting field of research and one of the competing avenues to demonstrate that quantum computers can complete certain problems that classical computers cannot. In photonics, however, we are only ...

Digital networks at the nexus of productivity growth

  • Kamat S.

  • Saniee I.
  • Weldon M.

This paper takes a fresh look at the debate over the relationship between digital technology and productivity. The argument of economic historian Robert J. Gordon is that digital technology will not lead to increases in productivity such as we saw in the last century, based on his analysis of the ...
