The Institute of Telecommunications Science and Technology has tackled the key issues of beamforming and space multiplexing technologies and has achieved great results. It invented the multi-antenna multi-stream beamforming technology based on the small pitch antenna array, and sent multiple beams through the small pitch antenna array. The data transmission and the wide coverage are realized. The method of three-dimensional resource scheduling and joint interference management is proposed, and the hierarchical interference model at the network level, cell level and user level is established, which greatly improves the system Capacity; developed wideband Orthogonal Frequency Division Multiplexing time division duplex transmission control and access technology, multi-stream beamforming technology obtained in the relevant international standards.
