A Radio Resource-Efficient Paging Method in High Frequency 5G Networks

  • Awada A.
  • Michalopoulos D.

Conventional paging methods are associated with increased radio resource overhead when deployed in high frequency networks. This is due to the beam sweeping involved, which, particularly for large number of beams, renders conventional paging inefficient. This work provides an assessment in terms of radio resource usage efficiency of an alternative ...

Scaling Deep Learning-based Decoding of Polar Codes via Partitioning

  • Cammerer S.
  • Gruber T.
  • Hoydis J.
  • Ten Brink S.

The training complexity of deep learning-based channel decoders scales exponentially with the codebook size and therefore with the number of information bits. Thus, neural network decoding (NND) is currently only feasible for very short block lengths. In this work, we show that the conventional iterative decoding algorithm for polar codes ...

Ultra-Dense Networks: A New Look at the Proportional Fair Scheduler

  • Amir H. Jafari
  • Guoqiang Mao
  • Lopez-Perez D.
  • Ming Ding
  • Zihuai Lin

In this paper, we theoretically study the proportional fair (PF) scheduler in the context of ultra-dense networks (UDNs). Analytical results are obtained for the coverage probability and the area spectral efficiency (ASE) performance of dense small cell networks (SCNs) with the PF scheduler employed at base stations (BSs). For the ...

Fairness vs. Performance in Rel-13 LTE Licensed Assisted Access

Wireless spectrum being a valuable resource, a large number of both non-profit and for-profit users rely on its unlicensed parts, usually to provide some sort of local area wireless coverage. When the cellular vendors and service providers expressed interest in the unlicensed spectrum, the incumbent community started to fear that ...

Dynamic TDD: the Asynchronous Case and the Synchronous Case

  • Guoqiang Mao
  • Lopez-Perez D.
  • Ming Ding
  • Zihuai Lin

Small cell networks (SCNs) are envisioned to embrace dynamic time division duplexing (TDD) in order to tailor downlink (DL)/uplink (UL) subframe resources to quick variations and burstiness of DL/UL traffic. The study of dynamic TDD is particularly important because it serves as the predecessor of the full duplex transmission technology, ...

A Comparison Between Different Reception Diversity Schemes of a 4G-LTE Base Station in Reverberation Chamber: A Deployment in a Live Cellular Network

The uplink performance of a real fourth-generation long-term-evolution (LTE) frequency-division multiplexing base station was observed by adopting a reverberation chamber as propagating environment. In the downlink direction, the reception of the LTE signal is limited to mobile station receivers. On the other hand, different reception schemes could be implemented by ...
