Panel 5: Evolution of 5G mmWave

Thursday 16 September, 16:00-18:00 (UTC/GMT +3)

The evolution of 5G New Radio (NR) has progressed swiftly since 3GPP standardized the first NR release, i.e., Release 15 in mid-2018. Release 16 was completed in early July 2020. Also in July 2020, 3GPP 5G spanning Release 15&16 was formally endorsed as ITU IMT-2020 5G standard. In addition to efficient utilization of sub 6GHz spectrum, Release 15&16 also provide the basic functionalities of supporting mmWave. Nowadays Release 17 has taken center stage. Technologies for enhanced mmWave are under discussion.

At the same time, 3GPP also starts to plan Release 18 and beyond. To enable large-scale mmWave network deployment, we still face lots of challenges, such as massive MIMO beamforming for outdoor and indoor coverage, cost-effective deployement solutions, seamless mobility with effective beam management, network and device energy efficiency, mobile device complexity and etc. In addtion to the existing challeges, there are lots of new emerging use cases for mmWave, such as uplink centric traffic, real time immsersive communications, positioning for IIOT, sensing. Therefore, it will be very timely to investigate how 5G mmWave evolves towards 2025 and beyond from technology points of view, taking into accounts the main use cases, key challenges and potential technology trends.

In this panel, we will bring together leading experts from the mobile industry. The panel can serve as a good opportunity to share the experts’ views about mmWave technology for 5G evolution and can provide a bridge between industry and academia.


  1. What are the challenges in the current 5G mmWave deployment worldwide?
  2. What are the emerging new use cases for mmWave toward 2025 and beyond?
  3. Considering those challenges and emerging new use cases, what are the top driving forces for 5G evolution on mmWave?
  4. What objectives and requirements for 5G evolution on mmWave?
  5. What are technologies for 5G evolution on mmWave to fulfill the above requirements?
