The cellular network evolution has generally focused on improving system and edge user throughput while reducing latency. Recently, a new class of service involving the communication of short packets has emerged wherein scale, coverage, reliability, and energy efficiency has greater importance than the rate or latency at which the information is delivered. This delay tolerant class of communication may include keep alive application messages from our smart phones or messages for the Internet of Things (IoT) and machine type communications (MTC). In this paper, we propose autonomous transmissions paired with interference cancellation to improve coverage, reliability, scale, and energy/spectral efficiency for delay tolerant short packet communications. Our simulation results demonstrate that up to 2x improvement in spectral efficiency can be achieved.

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 ...
