The present invention provides a single-user beamforming method suitable for a frequency division duplex system, comprising the following steps: obtaining a first transmission weight and a second transmission weight according to an uplink signal; using the first transmission weight to weight after adding a dedicated pilot of a layer 1 to a to-be-transmitted first data stream, and using the second transmission weight to weight after adding a dedicated pilot of a layer 2 to a to-be-transmitted second data stream; mapping the weighted first data stream to an antenna, mapping the weighted second data stream to the antenna, and sending them after superimposing them at the antenna port. The present invention also provides a single-user beamforming apparatus suitable for a frequency division duplex system. The present invention can send two data streams to one user at the same time, so it increases throughputs of user and system.
