Method, system and device for beam shaping transmission

A system for beam forming transmission, comprising an eNB and at least one UE,

• the eNB being configured to map 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, and to perform a resource mapping on 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 UE being configured to receive the DwPTS Field data,
• 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 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 special subframe, so as to obtain the number n of OFDM symbols carried in the DwPTS Field, wherein, n=T/To.

An eNB, comprising a data processing module and a transmitting module,

• the data processing module being configured to map 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 perform a beam forming process, and to perform a resource mapping on 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 transmitting module being configured to transmit the DwPTS Field data obtained by the data processing module to the UE,
• wherein the data processing module comprises a judging module, a resource mapping module and a beam forming processing module,
• the judging module being configured to obtain an OFDM symbol number carried in the DwPTS Field to determine a length T of the DwPTS Field and a length To of one OFDM symbol according to the type of a CP of the OFDM symbols and a specific configuration of the special subframe, so as to obtain an OFDM symbol number n carried in the DwPTS Field, wherein, n=T/To;
• the resource mapping module being configured to map 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 obtain the results of the beam forming process with the beam forming processing module, and to perform the resource mapping on the 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 beam forming processing module being configured to perform the beam forming process on the downlink service data and the UE-specific reference signals that are mapped by the resource mapping module according to the preset mapping structure.
