<p>Disclosed are a downlink multi-stream beamforming data transmission method and device, the method comprising the following steps: splitting existing user terminal dedicated ports - Port 7 and Port 8 into more than two user terminal dedicated ports; mapping each service stream data processed by an eNB into one or more of the split user terminal dedicated ports; using multi-stream beamforming to conduct cooperative transmission (and/or interference avoidance transmission) for the split user terminal dedicated ports mapped with the service stream data. The present invention splits the user terminal dedicated ports into more than two ports, and can be realized by an R9 protocol-based system via only small modifications, while the maximum downlink of the more than two ports exceeds a double-stream multiplexing transmission mode, thus improving multiplexing efficiency, changing neighboring cell interference into a useful signal and enhancing the throughput and coverage of an edge terminal.</p> |
