This paper presents a novel cooperative uplink inter-cell interference (ICI) mitigation algorithm based on joint reception at the base station using receiver adaptive beamforming in a Cloud Radio Access Network (CRAN). In extension the proposed algorithm exploits global network view of the centralised processing unit within the central office providing an attractive solution for Fibre-Wireless (FiWi) network infrastructures. Centralised processing allows for joint scheduling decisions for individual mobile users to be made based on the information received from different cells. As a result, uplink user transmission is scheduled according to the known positions of other users in order to minimise ICI. This is enhanced in operation by an advanced receiver beamforming technique that in corporation has the potential to improve the overall uplink capacity. Therefore the benefits of receiving uplink signals from a larger number of antennas, in different geographical locations, are investigated using the proposed techniques of FiWi uplink joint reception and coordinated scheduling. System level simulations have demonstrated significant improvement in mobile user throughput and received signal-to-interference-noise-ratio (SINR)
