By Dr. John E. Smee | Senior Vice President, Engineering, Qualcomm Technologies

This week kicks off one of the most important events of the year for the mobile industry — Mobile World Congress in Barcelona (MWC22). The focus this year is on 5G Advanced, which starts the second phase of the 5G decade and will bring to the world a new wave of wireless innovations. Today, we are at the starting line of this evolution as the work for 5G Advanced Release 18 is expected to begin shortly.

To prepare, we have been conducting research in many areas of wireless, and we believe this work will ultimately bring us another step closer to 6G by the end of this decade. In this blog post, I’ll walk you through 10 key wireless innovation areas that will fuel the 5G Advanced evolution toward 6G — five in the area of foundational air interface enhancements and five in 5G expansion into new applications and verticals. At the same time, I will also provide a short preview of our MWC22 technology demonstrations in each area. You can also see them in action at MWC22 YouTube playlist.

Five air interface enhancements for 5G and beyond

At Qualcomm Technologies, we have been driving the advancements of cellular air interface designs for many decades. Looking forward to 5G Advanced and the path to 6G, we continue to push the technology envelopes that can improve the overall performance and efficiency of the cellular system.

Below are the five areas of system innovations, not in any particular order, that our research teams have been working on.

1. Advanced MIMO Evolution

We continue to lead the technology curve of complex RF and massive MIMO antenna designs that can deliver new levels of performance, efficiency, and flexibility. This year, we have prepared three demos that showcase our longer-term research.

  • Subband full duplex (SBFD): our real-time OTA prototype in San Diego can now support simultaneous downlink and uplink transmissions, utilizing a single antenna divided into two subband panels. SBFD brings additional network capacity and lower latency communications.
  • Upper mid-band expansion with Giga-MIMO: we continue to make new spectrum bands viable for cellular communications. Giga-MIMO, which can utilize an order of magnitude more antenna elements than 5G massive MIMO, unlocking more wide-area bandwidth in the upper mid-band (i.e., 7—24 GHz).
  • Sub-THz lensed MIMO: a key vector for 6G is the utilization of new spectrum bands. This demo showcases how a lensed MIMO design can efficiently unlock wider bandwidths in the 100+ GHz spectrum to deliver 100s of Gbps throughput suitable for diverse use cases.
