Efficient Signal Processing and Radio Resource Management (RRM) for Coordinated Multi-node Downlink Transmission in Heterogeneous Cellular Networks

Reliable high speed wireless data transmission is the primary goal of future cellular systems. A key impediment
towards that goal is interference on receivers from transmitters in adjacent cells. Coordinating transmissions
between clusters of transmitters is one way of solving this problem. This coordination is more difficult when the
types of transmitters and cell sizes vary within a heterogeneous network (HetNet). The design of HetNets is an
emerging research field. This project has three main goals: 1) Investigate the design of coordinated HetNets. 2)
Design efficient resource allocation algorithms for these networks, for the selection and encoding of users and
their data, and the dynamic formation of clusters of transmission points. 3) Investigate how best to reduce the
feedback overhead in the sharing of information within a cluster, and the impact of this limited feedback. This
research will allow the partners to gain relevant expertise and impact the design of future wireless standards.
