Energy Saving via Efficient Allocation of Paging Frames

  • Awada A.
  • Michalopoulos D.

We propose an alternative design for paging in next generation networks, and investigate its potential for increasing the energy efficiency of base stations. The proposed design allocates the paging frames in certain radio frames, aiming at providing longer sleep opportunities to the base stations. This allows more hardware components to be deactivated and reduces the number of transitions between active and sleep mode, leading to lower energy consumption. The resulting energy saving is evaluated and compared with that of the reference paging scheme. Numerical results demonstrate that noteworthy energy savings are achieved for certain parameter configurations.

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 ...
