A New Relaying Protocol For 5G Small Cell With Wireless Backhaul Channels

  • Claussen H.
  • Fang D.

In this paper, we propose a network coding enabled wireless backhaul (NC-WB) for the next generation small cell networks. NC-WB aggregates the access and backhaul links to the same frequency band for wireless backhaul small cells. The smallcell base stations (SBS) generate the network coded functions of the signals coming from user equipments (UE) and macrocell base station (MBS), i.e., SBS does not separate incoming composite signal but map it into a linear combination of Tx signals instead. The resulted network coded functions are broadcasted to UEs and MBS. This design allows MBS and UE to exploit the side information and network coded functions to extract the desired signals. Compared with the conventional relaying protocol in wireless backhaul small cells, the proposed approach almost doubled the spectral efficiency.

  • 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 ...

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 ...
