WS05: The 4th International Workshop on High Capacity Wireless Communications (HCWC)

WS05: The 4th International Workshop on High Capacity Wireless Communications (HCWC)


Toward 6G increasing the capacity of wireless communication becomes essential. Looking into the era of  6G when various types of wireless usage are becoming mature, capacity of base stations should be large enough to accommodate these diversely increasing traffic. It is utmost important to consider the vision and core technologies for the 6G era. Among various aspects, it is no doubt that mobile traffic will continuously increase and the demand for large-capacity wireless transmission will continue to grow as 5G accelerates usage of wireless communications in all sorts of fields including connected cars, virtual-reality/augmented-reality (VR/AR), and high-definition video transmission. Considering such mobile traffic growth trend, it is expected several hundred gigabit-class to terabit-class wireless transmission is necessary to support demand for wireless communications in the 2030s.  

    In the previous workshops, we revisited the point-to-point wireless communication with focus on the realization of high capacity. Then, we expanded the scope to include both point-to-point and point-to-multipoint communications that achieve “high capacity” to actively cope with new challenges and demands toward 6G. In this workshop, we further expand the scope to include various technologies that enables the “high capacity” such as photonics-aided wireless communication, FSO, and hybrid THz and mmWave communications. At the same time the scope of this workshop includes various perspectives such as potential applications, system consideration, and wireless transmission technologies. In the application and system perspectives, realization of high capacity wireless fronthaul/backhaul as well as integrated access and backhaul might be examples. Of course, other related topics are included in the scope. To ensure complete coverage of the advances in this field, this workshop calls for original contributions in, but not limited to, the following topical areas: 

   - Vision and expectation for 6G
 - Usage scenarios of high capacity wireless communications 
 - Wireless fronthaul, backhaul, integrated access and backhaul
 - OAM multiplexing wireless communications
 - THz/mmWave wireless communications
 - Line of sight MIMO wireless communications, Holographic MIMO, RIS
 - Optical wireless communications, free space communications
 - Hybrid optical and wireless communications
 - Photonics-aided wireless transmission
   - Device technologies
 - Proof of concept experiments
