| Abstract(in English) | In ultra-dense mobile radio communication systems, severe co-channel interference is produced by reusing the same radio resource in a very close distance and this interference limits the enhancement of capacity and reliability of the system. Hence, the interference countermeasure will become one of key technical issues in beyond 5G systems. The ultra-dense radio access network (RAN) needs to be designed with interference countermeasure in mind and its system structure will become different from those of 5G systems. In this report, we will present the architecture of reconfigurable cellular distributed MU-MIMO system aiming at the realization of ultra-dense RAN having a large capacity as well as enhanced reliability, adaptability, and scalability. Then, we will introduce a concept of interference countermeasure suitable for the reconfigurable cellular distributed MU-MIMO system. |
