Cloud radio access network (C-RAN) is becoming more than ever timely in 5G for dense network deployments, but its design has to be adapted to 5G requirements. To ensure high-uplink throughput in cell-edge regions affected by inter-cell interference, C-RAN enables the multi-user reception techniques among cells. In this paper, we propose an efficient end-to-end uplink transmission scheme dealing with...
Aiming to throughput enhancement in future mobile networks, dense deployment of wireless access points (APs) is intended. Spectral efficiency on the uplink can be improved via joint processing of users located in areas covered by several APs. Thanks to centralized processing of such users enabled by Cloud Radio Access Network (C-RAN) architecture, low-latency multi-cell cooperation becomes possible...
Centralization of base-band processing in mobile networks is a key element of 5G architecture and aims to achieve significant performance and efficiency gains. Large transmission bandwidth and high number of antennas require an adaptation of Cloud Radio Access Network (C-RAN) architecture in order to realize efficient and affordable data transfer between remote units (RUs) included in the distributed...
Coordination between neighboring cells is intended to be implemented in future mobile networks, since it promises significant performance gains. Despite low-latency cooperation made possible by Cloud Radio Access Networks (C-RAN), practical feasibility and improvements brought to a real system were still to be evaluated. We define in this paper an architecture based on the abstraction and scalability...
To meet quality of service requirements on the uplink of future cellular networks, we need to exploit inter-cell interference among users eligible for cooperation. Cloud Radio Access Network (C-RAN) architecture is particularly favorable to realize cooperation between users in neighboring cells, since signal detection is realized in the same processing unit. The novel technology of Software Defined...
