12. Concluding Remarks
There are 5 requirements for the 5th generation mobile communication (5G) such as "Massive connection", "Low cost and low power consumption", "Low latency", "High transmission speed", "High capacity". Because we discussed the latter 2 issues at the URSI-C technical meeting held on June 29th, 2018, we had a meeting to discuss about the former three issues, and the technical trend and perspective of the beyond 5th generation cellular communication systems.
The five researchers working on such issues were invited to talk about cutting edge technologies and standardization activities for the IoT network with the 5th generation cellular systems and the beyond 5th generation cellular systems.
Although business models of the IoT have not been established well, wireless assisted car driving, one of the applications of the IoT, was introduced as one of the very promising applications.
The techniques to implement the wireless assisted car driving have been discussed in the third Generation Partnership Project (3GPP) where standardization of the 5th generation cellular system is discussed, and the 5G Automotive Association (5GAA) where the requirement for the wireless car driving is discussed. Although there are still some important issues left, definitely those techniques are interesting.
