<p>Existing solutions eliminating interference among cells based on base station collaboration have drawbacks such as resource consumption, Backhaul burden increase etc. This invention presents a low-information interactive multi-base station collaborative MIMO and corresponding scheduling method and apparatus. The base station accesses signal quality relevant information of nearby mobile end-equipment, reports to scheduling apparatus, where signal quality relevant information is best embodied as RSSI or CQI for smaller size. Thereafter, scheduling apparatus chooses service base station for each mobile end-equipment, determines which base station needs to eliminate interference for which mobile end-equipment. The scheduling apparatus also controls sending service data of mobile end-equipment to service base station correspondingly. The base station determines the end-equipment which it serves and where the interference is eliminated based on scheduling apparatus' indications. The base station only needs to know the channel status information between said base station relevant mobile equipment and said base station upon corresponding time frequency resource, calculate pre-coding matrix, and pre-codify mobile equipment service data the said base station serves to form downlink signalready to send. Said procedure takes place when one base station needs to serve mobile end-equipment on one time frequency resource and eliminate interference for other mobile end-equipments. The said procedure is among the base stations.</p> |
