Where Mobile Meets Cloud - Journey to 5G with vRAN / NFV

  • Reinink K.
  • Segel J.
  • Urie A.

This chart set describes the role of virtualization and NFV in effecting the transition from VRAN 4G LTE to 5G; 5G will bring a broad range of new services at various capability, price, cost and performance points with a focus on end-to-end services and flexible personalization. New technologies such as virtualization, life-cycle management automation and orchestration, already being implemented in VRAN, will lay the foundation for the transition to 5G end-to-end services; the proposed service management architecture to deliver such services is presented.

Fair Dynamic Spectrum Management for QRD-Based Precoding with User Encoding Ordering in Downstream G.fast Transmission

In next generation DSL networks such as G.fast, employing discrete multi-tone transmission in high frequencies up to 212 MHz, the crosstalk among lines reaches very high levels. To precompensate the crosstalk in downstream transmission, QRD-based precoding has been proposed as a near-optimal dynamic spectrum management (DSM) technique. However, the performance ...

Practical Mitigation of Passive Intermodulation in Microstrip Circuits

This paper presents new experimental evidence and a novel practical approach for mitigation of passive intermodulation (PIM) in microstrip circuits fabricated on commercial printed circuit board laminates. The mechanisms of distributed PIM in microstrip circuits are reviewed and a phenomenology of PIM generation due to locally enhanced electromagnetic fields at ...

Efficient Cooperative HARQ for Multi-Source Multi-Relay Wireless Networks

In this paper, we compare the performance of three different cooperative Hybrid Automatic Repeat reQuest (HARQ) protocols for slow-fading half-duplex orthogonal multiple access multiple relay channel. Channel State Information (CSI) is available at the receiving side of each link only. Time Division Multiplexing is assumed, where each orthogonal transmission occurs ...
