SIG on Cognitive Radio for 5G

Scope and Objectives

To meet the explosively growing demands for high-speed mobile broadband, many efforts have been done on the development of 3GPP Long-Term Evolution (LTE) cellular systems. Recently, the wireless industry has been focusing on the research of the Fifth Generation (5G) cellular systems, which are expected to be first deployed in the year of 2020. As we all know, one of the fundamental issues is the increasing challenge of acquiring adequate spectral resources in radio frequency bands to operate 5G cellular systems. All over the world, a large amount of spectral resources are still utilized in a static and therefore, inefficient manner. Hence, Cognitive Radio (CR), with the capability to be aware of radio environments and flexibly adjust its transceiver parameters, has drawn much attention in academia and recently also in industry and has been proposed as an enabling technique to dynamically access the underutilized spectral resources.

The previous research on CR was focusing on improving the utilization of radio spectrum resources mainly within the primary-secondary user models in the UHF TV band. In 5G wireless communications, to meet the challenging requirements of huge capacity, massive connectivity, high reliability and low latency, CR is expected to play an important role in two aspects. First, since the spectrum band for 5G will be extended to even millimeter-wave range, CR can still be used to improve the spectrum utilization while protecting much larger range of coexisting users and within broader types of spectrum sharing models, such as licensed spectrum sharing (LSA) and dynamic spectrum leasing etc. Second, 5G will take aggressive spatial reuse of spectrum as one of the key enablers with new techniques such as massive MIMO and Ultra-dense Deployment. In this context, CR can be used to mitigate the interference issues from space, frequency and time domains with a very dynamic manner.

The proposed Special Interest Group will focus on the convergence of Cognitive Radio and 5G system. The motivation of establishing this Special Interest Group is to tightly connect researchers from both academia and industry so that they can conveniently exchange their creative ideas, cutting-edge research activities, and state-of-the-art advancements in techniques and solutions on CR for 5G. We propose the following sub-topics:

  • Spectrum sensing with focus on 5G cellular systems
  • Radio environment map/Geo-location database for 5G cellular systems
  • Cognitive Radio with Massive MIMO for 5G communications
  • Physical layer algorithms for cognitive radio in 5G cellular systems
  • Medium access control for 5G cognitive networks
  • Localization technique in 5G cognitive networks
  • Device-to-device communications in 5G cognitive networks
  • Cognitive technologies in 5G public safety communications
  • Cognitive small cells in 5G cellular systems
  • Test-beds and prototypes for 5G cellular systems
  • Business models, standardizations and regulations for 5G cellular systems
