Patent ID: 8526295

Claim:
A method for beam forming transmission, comprising the following steps: an eNB mapping downlink data of a user and UE-specific reference signals carried in a DwPTS Field for beam forming transmission according to a preset mapping structure, and performing a beam forming process; the eNB performing a resource mapping for results of the beam forming process, primary synchronization signal, control signaling, Cell-specific reference signals and other user data to form the DwPTS Field data; and the eNB sending the DwPTS Field data to the UE, wherein the preset mapping structure depends upon the number of OFDM symbols carried in the DwPTS Field, and wherein the number of OFDM symbols carried in the DwPTS Field depends upon the type of a cyclic prefix CP of the OFDM symbols and the specific configuration of the special subframe, and the eNB determines a length T of the DwPTS Field and a length To of one OFDM symbol according to the type of the CP and the specific configuration of the DwPTS Field, so as to obtain the number n of OFDM symbols carried in the DwPTS Field, wherein, n=T/To.
