Title:
MULTI-CODEWORD TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/149273
Kind Code:
A1
Abstract:
The application discloses a multi-codeword transmission method and device. The method comprises: network equipment generating downlink control information corresponding to each of a plurality of codewords of terminal equipment, wherein the downlink control information corresponding to each of the codewords comprises at least one of the following: a physical downlink shared channel resource element mapping indication and a quasi-co-location information indication, an antenna port, a scrambling indication, and a layer number; and the network equipment transmitting to the terminal equipment the downlink control information of the plurality of codewords. Also disclosed is a corresponding device. In the technical solution of the application, the network equipment generates the downlink control information corresponding to each of the plurality of codewords of the terminal equipment, the terminal equipment can perform data demodulation on the plurality of codewords according to the downlink control information of the plurality of codewords, ensuring accuracy of data demodulation at terminal equipment in a multi-codeword transmission scenario.
