In this talk, we present the development of massive MIMO antenna technologies for the 5G and associated challenges. The overall system performance and antenna design-choice in terms of spectrum and channel propagation properties are discussed. In particular. The novel massive MIMO antenna design to achieve higher capacity with same antenna aperture size and the field trial results are presented. We explore the centimeter wave spectrum for 6G, and the next generation of massive MIMO. The candidate frequency range is from 7GHz to 15GHz, we discuss the new propagation properties and ultra-large antenna element array architecture for both base-station and user-equipment. The 6G centimeter-wave MIMO signal processing represents the new opportunities and challenges to advance the classical MIMO technology.

Keynote 02: Understanding 6G Modulation to Mitigate Doubly Dispersive Channels – OTFS and Alternatives
Tuesday 13 September, 17:15-18:00 (UTC +9)
Due to an increase in bandwidth as well as carrier frequency, mobile communications channels can become doubly dispersive, i.e. in time and in frequency. The increase in carrier frequency at constant velocities of mobile terminals also reduces the coherence time. This results in possibly reducing the chance of acquiring channel state information at the transmitter, and therefore using precoding techniques. Given these boundary conditions a modulation technique is to be found that is robust against doubly dispersive channels for transmitters without channel state information.
For this case, OTFS has been proposed, as it spreads information over time as well as over frequency. It therefore provides the resilience that is searched for. However, it is only a special case. This talk wants to show the general concept of creating the searched robustness, and some specially interesting alternatives to OTFS.

Sony Group’s ambition is to change the entertainment industry with Private 5G. There is a growing need in the manufacturing industry, one of the major business areas of Sony Group, to improve production efficiency by introducing advanced digital tools such as IoT and AI over reliable telecommunication infrastructure. Among various types of telecommunications, wireless communication technology is especially useful in factories since production line changes and equipment reallocations occur frequently. The 5G wireless technology, characterized by Ultra-high Bandwidth (eMBB), Ultra Reliable Low Latency Communication (URLLC), and massive Machine Type Communications (mMTC), is expected to bring further changes in the manufacturing industry. Private 5G in particular is promising as communication bandwidth is secured. It is expected that in the future the manufacturing business will expand its scope into areas of virtual production in addition to the existing physical production, as we see growing attention to areas such as metaverse and digital twins. Such shift will start in the entertainment field, such as content creation and gaming. The process of producing entertainment content is similar to those in the manufacturing field as creation, editing and distribution take place simultaneously. The process here is ‘Inside the large production studio, many staffs use different devices at the same time, then the edited content is sent and received between devices, and final outputs created is delivered to end users in real-time”. Therefore, we believe the entertainment field has a high affinity with Private 5G. In this speech, I will talk about how Private 5G will positively impact the production operation side of the entertainment field, and how Sony Group, which runs multiple lines of entertainment businesses, will take on the challenge of such transformation.

Visual inspection and monitoring systems are being deployed at a rapid rate in a number of settings, including manufacturing plants, warehouses, office buildings, retail stores, hospitals and homes and generate a large amount of image, video, and 3D point cloud information. While many sources of such data are directly wired to infrastructure networks, the need for mobile platforms that capture imagery in the same settings also has increased demand on wireless links. The need will only grow as humans and autonomous systems collaborate on a larger scale in dynamic environments. In addition, the consumers of the data are now less often humans monitoring screens and more often learning algorithms whose performance is adversely impacted by typical image and video compression artifacts. Finally, while more computation is now being performed at network edges due to advances in computer architecture and silicon process technology, many applications such as identifying items, validating proper implementation of workflows or path planning in active workspaces require access to large amounts of previously-acquired information, necessitating a prohibitive amount of storage at the edge nodes. Inevitably, large amounts of imagery will be transmitted back to remote servers and storage in the cloud. Applications with real timing deadlines including control and coordination of autonomous lifts in warehouses, workplace safety monitoring, fall detection, automated check-out, interactive games and many more will drive bandwidth demand and latency limits.
