In this paper we analyze various user assignment and scheduling policies for neigbouring femtocell networks. The trade-off between capacity maximization and fairness is investigated and a combined user assignment and proportional fair (PF) scheduling procedure for a femtocell gateway is proposed. The flexibility of the proposed architecture in terms of capacity and fairness is studied via various...
3GPP/LTE femtocell dense deployment scenarios set new challenges in terms of interference and Radio Resource Management (RRM). Traditional policies are mainly designed for classical cellular networks, while femtocells ad-hoc nature notably limits the possible algorithm complexity. Furthermore, efficient RRM algorithms are essential in limiting interference impact to femtocells performance. In this...
This paper proposes a number of novel uses for 3D location and environmental geometry information to enhance the performance of the wireless physical layer. In the context of this paper, such information is obtained in real-time from a mobile operative carrying the ViewNet system. A location-based multi-user scheduler is proposed to exploit multi-user diversity by choosing users with wide angular...
MIMO downlink with base station coordination in a cellular network is considered. In centralized coordinated transmission from a cluster of base stations, the channel state information (CSI) of users needs to be sent to a central processor for user scheduling and resource allocation. Real time CSI feedback from the users to their home base station and from the base stations to the central processor...
