A retrospective interference reconstruction (RIR) scheme was proposed for the uplink multi-cell multiple-input multiple-output (MIMO) cellular interfering network with delayed feedback.The main idea of RIR is to eliminate the inter-cell interference based on the delayed output feedback (OF).The received beamforming matrix is used to reconstruct the interference signal at each base station (BS).Each BS feeds the reconstructed OF back to its corresponding user.Subsequently

the corresponding user for each BS utilizes the delayed OF to precode information and sends the precoding information to its served BS.The precoding information is used to eliminate all interference signals at each BS.The achievable degrees of freedom (DoF)

the achievable sum rate and the application conditions of RIR scheme were analyzed for the uplink multi-cell MIMO cellular interfering network with arbitrary number of cells.Experiment results show that the RIR scheme can provide significant DoF gain over the time division multiple access (TDMA) and the existing retrospective interference alignment schemes.
