The aim is to reduce intercell interference in order to protect users, especially at the cell edge. The strategy consists of appropriately splitting the available bandwidth and is shown to be well-suited to scenarios where the number of cell-edge users is considerable. For a system comprising two cells each with a base station of Nt antennas, it is shown that, compared to a previous augmented code approach where transmission to all users occurs in the same frequency band, the proposed strategy leads to better rates over a wide range of signal-to-noise ratios when the number of cell-edge users in both cells exceeds 2Nt -1.6application/pdfeng© 2014 IEEEBandwidthInterferenceNISTSignal to noise ratioTransmitting antennasconference paperTelecomunicacionesopen access57355740IEEE International Conference on Communications (ICC), proceedingsCC/0000021482
