Call For Papers

In the past year, 5G has been evolving at a faster rate, showing its massive potential. However, current 5G networks predominantly focus on meeting downlink requirements of consumers. As new uplink-centric applications keep emerging in the market, 5G must constantly improve its uplink connection capabilities. Various consumer AR/XR services require high-definition images and videos to be sent from local devices to clouds for further rendering. Remote control and machine vision in industrial applications also require real-time transfer of 4K and 8K videos. This will lead to a considerable increase in the proportion of uplink traffic over 5G networks to above 40%. To deal with such a huge amount of uplink traffic, 5G uplink capabilities must be improved by at least 10 times.
It is believed that the evolving MIMO technology will be one of the indispensable and important means for that target. For example, massive receiving antennas at base stations and multi-cell joint reception significantly enhance the uplink signal strength. At the same time, novel MIMO architectures such as extremely large aperture arrays (ELAA) and intelligent arrays, and advanced MIMO systems in user centric no cell (UCNC) and cell free deployments, are also promising directions for ubiquitous high-rate low-latency uplink transmission. Furthermore, the improvement of the transmit capability of terminals also plays a pivotal role such as increased number of transmit antennas and higher transmit power at terminals as well as cooperative multi-terminal transmission.
This workshop will bring together attendees from both academia and industry to share their latest progress in MIMO technology and identify open research problems, technical challenges and the potential evolution of the MIMO technology for Uplink-Centric Broadband Communication (UCBC).
