Abstract

Ultra-densification of radio access network (RAN) is necessary to handle ever-increasing mobile data traffic even after starting of 5G services. Dense reuse of the same radio resource produces severe interference. Furthermore, when extremely high frequency band like mmWave band is utilized, the radio link may be frequently blocked by obstacles placed between transmitter and receiver according to user movement. To realize highly reliable communications in such a severe radio link environment, an enhanced interference coordination (eIC) and radio resource management (RRM) needs to be introduced. In this paper, we will present the concept of an eIC and RRM for 5G advanced ultra-dense RAN using distributed MIMO, which integrates a classification of user-equipments (UEs) into inner-cell and cell-edge groups, UE clustering, cluster-antenna association, distributed MIMO cooperative transmission reception (CTR), and scheduling. Then, we will present some preliminary results obtained by numerical computation.
