To implement the ultra-dense wireless access network required for fifth generation (5G) and beyond networks, the “cloud-RAN” and now the “virtualised RAN” paradigms have been developed. These involve a large number of distributed antennas or remote radio units (RRUs) connected to separate baseband units (BBUs) at which the signal and data processing is carried out. The BBUs are either centralised on large servers in the “cloud”, or else distributed within the network infrastructure. There is currently much research on where they should be located, how they should be connected to the RRUs, and how they should be implemented, including the distribution of various signal processing functions between different. The project will investigate a number of options for the transmission of signals, including vector quantization, lattice coding and compressive sensing, and evaluate the overall network performance when functions are implemented in different locations. We have industrial partners who are interested in this work, who may provide us with information on the practical constraints of implementing the network.
