Description

Information transmission method, apparatus, storage medium, and program product Technical Field The present disclosure relates to the field of communications technologies, and in particular, to an information transmission method, apparatus, storage medium, and program product. Background In a communication system, demodulation reference signals (DEDICATED DEMODULATION REFERENCE SIGNAL, DMRS) are used to demodulate signals when transmitting data. When the DMRS is transmitted, one DMRS port corresponds to a plurality of DMRSs, and different DMRS ports are associated with different transmission data layers. In order to increase the transmission capacity of a communication system, increasing the number of transmission data layers is the most straightforward means. However, the number of DMRS ports supported by the current user is small, and the number of increased transmission data layers cannot be satisfied. Disclosure of Invention The embodiment of the disclosure provides an information transmission method, an information transmission device, a storage medium and a program product, which can adapt the number of supported DMRS ports to the number of increased transmission data layers. In one aspect, an information transmission method is provided, which includes receiving first indication information, where the first indication information is used to indicate DMRS configuration, and the DMRS configuration is associated with pattern information corresponding to a DMRS and/or orthogonal code OCC information corresponding to the DMRS. In still another aspect, an information transmission method is provided, which includes sending first indication information, where the first indication information is used to indicate DMRS configuration, and the DMRS configuration is associated with pattern information corresponding to a DMRS and/or OCC information corresponding to the DMRS. In still another aspect, an information transmission apparatus is provided, which includes a receiving unit, configured to receive first indication information, where the first indication information is used to indicate DMRS configuration, and the DMRS configuration is associated with pattern information corresponding to a DMRS and/or orthogonal code OCC information corresponding to the DMRS. In still another aspect, an information transmission apparatus is provided, including a transmitting unit, configured to transmit first indication information, where the first indication information is used to indicate DMRS configuration, and the DMRS configuration is associated with pattern information corresponding to a DMRS and/or OCC information corresponding to the DMRS. In yet another aspect, an electronic device is provided, including a memory and a processor, the memory and the processor being coupled, the memory being configured to store a computer program, the processor implementing the information transmission method according to any of the embodiments described above when executing the computer program. In yet another aspect, a computer readable storage medium is provided, on which computer program instructions are stored, which when executed by a processor implement the information transmission method according to any of the above embodiments. In a further aspect, a computer program product is provided, comprising computer program instructions which, when executed by a processor, implement the information transmission method according to any of the embodiments described above. The embodiment of the disclosure discloses that a first node may receive first indication information for indicating a DMRS configuration, where the DMRS configuration is associated with pattern information corresponding to a DMRS and/or orthogonal code OCC information corresponding to the DMRS. Since the pattern information and the OCC information are related to the maximum DMRS port number supported by the DMRS configuration, the maximum DMRS port number corresponding to the DMRS configuration can be increased by indicating the pattern information and/or the OCC information supporting more maximum DMRS port numbers, so that the method can be adapted to the increased number of transmission data layers.
