5G waveform enabling the support of 100x devices with up to 10x lower latency

One driver for 5G is the vision to support a multitude of service and device classes. Bell Labs has invented a new waveform and access structure: Universal-Filtered OFDM (UF-OFDM) with an unified frame structure for handling this heterogeneity. This will enable a highly scalable and flexible system with improved spectral properties and higher robustness against crosstalk and relaxed synchronicity operation. Based on those innovations, the 5G system can increase the number of devices up to 100x, save battery times up to 10x at the device and offer modes with up to 10x lower latency.

A Cloud Native Approach to 5G Network Slicing

  • Francini A.
  • Miller R.
  • Sharma S.

5G networks will have to support a set of very diverse and often extreme requirements. Network slicing offers an effective way to unlock the full potential of 5G networks and meet those requirements on a shared network infrastructure. This paper presents a cloud native approach to network slicing. The cloud ...

  • Wu Q.

Based on the physical model of a bulk reflective semiconductor optical amplifier (RSOA) used as a modulator in radio over fiber (RoF) links, the distributions of carrier density, signal photon density, and amplified spontaneous emission photon density are demonstrated. One of limits in the use of RSOA is the lower ...

How to preserve users' privacy while supporting high-utility analytics for low-latency stream processing? To answer this question: we describe the design, implementation and evaluation of PRIVAPPROX, a data analytics system for privacy-preserving stream processing. PRIVAPPROX provides three properties: (i) Privacy: zero-knowledge privacy (ezk) guarantees for users, a privacy bound tighter ...
