Scope and Objectives

For the sake of enhancing the exploitation of the permanently allocated, but potentially under-utilized spectral resources, sharing the frequency bands between radar and communication systems has attracted substantial attention, which motivates the research of Integrated Sensing and Communications (ISAC) designs. In general, there are two main research directions in ISAC: 1) Radar-communication coexistence (RCC) and 2) Dual-functional Radar-Communication (DFRC) system design. The first category of research aims at developing efficient interference management techniques, so that the two systems can operate without unduly interfering with each other. On the other hand, DFRC techniques focus on designing joint systems that can simultaneously perform wireless communication and remote sensing, which benefits both sensing and signaling operations via real-time cooperation, de-congests the RF environment, and allows a single hardware platform for both functionalities. This type of work has been extended to numerous novel applications, including vehicular networks, indoor positioning and covert communications.

This newly established special interest group seeks to bring together contributions from researchers and practitioners in the area of wireless communications and sensing with an emphasis on new approaches and techniques for joint communication and sensing designs. The are a number of sub-areas of interest including, but not limited to:

  • Fundamental information theoretical limits for ISAC
  • Network architectures and transmission protocols for ISAC
  • Waveform/sequence/coding/modulation/beamforming design for ISAC
  • MIMO, massive MIMO, and intelligent reflecting surface (IRS) for ISAC
  • Millimeter wave and THz ISAC
  • Security and privacy issues in ISAC
  • ISAC design in vehicular-to-everything (V2X) networks
  • ISAC design in unmanned aerial vehicle (UAV) networks
  • Machine learning/AI enhanced ISAC
  • Radar and communication coexistence/spectrum sharing
  • Passive sensing using communication waveforms
  • Wi-Fi sensing for indoor positioning and target detection
  • Radar-assisted low-probability-of-intercept (LPI) communications
  • System-level simulation, prototyping, and field-tests for ISAC
