Signaling indication method and device, communication node, and computer storage medium

A signaling indication method, comprising:

• acquiring joint indication information;
• and
• transmitting the joint indication information to a second communication node, wherein
• the joint indication information is used for joint indication,
• the joint indication information comprises demodulation reference signal DMRS information, and
• the joint indication information further comprises at least one of:
• data modulation scheme, data coding scheme, transmission resource allocation, retransmission redundancy version RV, phase noise tracking reference signal PTRS, hybrid automatic repeat request HARQ process, time unit structure and data indication information,
• wherein
• the DMRS information comprises at least one of:
• a sequence number of DMRS port, a number of layers of data transmission and a DMRS pattern, wherein the DMRS pattern comprises at least one of:
• a number of DMRS time domain symbols, DMRS frequency domain density, information on whether DMRS and data are simultaneously transmitted, and multiplexing scheme of a plurality of DMRS ports in a time domain, and positions of time domains of a first subset and a second subset of the DMRS;
• and
• responsive to determining that the DMRS information and PTRS configuration information are jointly indicated, the DMRS information is configured to indicate whether the plurality of DMRS ports uses code division multiplexing CDM on a plurality of time domain symbols,
• wherein the PTRS configuration information comprises information indicating presence of PTRS.
