We are delighted to invite you to the IEEE Tutorial on Spectrum Sharing for Inter-Technology Coexistence 2020. The tutorial will be held online in December 2020, in conjunction with GLOBECOM 2020.

Why is this tutorial relevant?

Spectrum sharing for wireless technology deployments is changing. In the last few decades, there has been a massive increase in data traffic volumes and at the same time offered wireless services have become very diverse. This triggered network densification and an increasing number of bands shared by multiple technologies. Prominent examples include:

  • the 5 GHz unlicensed band for Wi-Fi/LTE coexistence
  • the 3.5 GHz Citizens Broadband Radio Service (CBRS) band in the U.S.
  • mm-wave bands for IEEE 802.11ad/y Wi-Fi, 5G-and-beyond cellular networks, and distributed radar sensing systems
  • the 6 GHz band, which was recently opened for unlicensed use.

We thus expect high interference levels and complex wireless inter-technology interactions. The challenge that arises is to manage these aspects through efficient spectrum sharing mechanisms and potentially changes in spectrum regulation, in order to achieve inter-technology coexistence and successfully provide desired services.

What does the tutorial cover?

The tutorial addresses the design of spectrum sharing mechanisms for inter-technology coexistence. Key technical and non-technical aspects are covered:

  • the spectrum regulation landscape and trends pertinent to spectrum sharing
  • the state of the art of spectrum sharing mechanisms for inter-technology coexistence, with a focus on MAC and PHY
    design and performance evaluation
  • key coexistence case studies and lessons learned, e.g. Wi-Fi/LTE coexistence and LTE/NB-IoT coexistence
  • emerging inter-technology coexistence cases in 5G-and-beyond mm-wave spectrum
  • spectrum management between Wi-Fi 6E and incumbent services in the 6 GHz band
  • open research questions.
