interference relation table airt through block 145 by which it will identify suitable cells for resources coordination by means of a direct interface with bsb bsa will coordinate time and or frequency resources through block 144 regarding the beams identified in the airt bsb will coordinate resources with bsa as well as with other base stations through block 148 and will also construct its own airt through block 149 according to the air reports received from its own connected users coordination is thus possible with multiple cells according to the contents of the airt table the present invention exploits the possibilities of advanced beamforming in wireless massive mimo systems by allowing coordination of beams between neighbour cells a new physical channel is introduced with the purpose of containing a suitable beam indicator with the property of carrying different beam information for each user by means of the spatial separation provided by beamforming with this new channel a procedure for collecting interference relationships by the terminals and reporting them to the base station is proposed thus extending traditional neighbour relationships such as anr in lte to more dynamic interference relationships dealing individually with interfering beams with this information the victim and aggressor cells can coordinate resources on a per beam basis by adjusting both time and or frequency resources in order to avoid collisions between the serving and interfering beams one of the drawbacks of massive mimo systems is the resulting pilot and or signal contamination which may arise if the beams from adjacent cells are not coordinated thus giving rise to significant interference enhanced by the beamforming process introduction of air.
