Abstract:
The present invention discloses a method for beam forming transmission, comprising the following steps: the eNB mapping the downlink data of the user and the UE-specific reference signals carried in the DwPTS Field for beam forming transmission according to the preset mapping structure, and performing the beam forming process; the eNB performing the resource mapping on results of the beam forming process result, primary synchronization signal, control signaling, Cell specific reference signal and other user data to form the DwPTS Field data; and the eNB sending the DwPTS Field data to the UE. The present invention further discloses a system and a corresponding device for beam forming transmission. The present invention can realize beam forming transmission in the Special Field DwPTS and improve the performance of the system without introducing a new user UE-specific reference signal mapping structure, which is simple to be realized.
