1. A method for determining a transmission mode, comprising:
obtaining configuration indication information, the configuration indication information comprising demodulation reference signal (DMRS) indication information, or a combination of repeated-transmission indication information and transmission configuration indication information, wherein the DMRS indication information indicates one or more DMRS port identifiers; and
determining a transmission mode based on the configuration indication information;
when the configuration indication information comprises the DMRS indication information, the determining the transmission mode based on the configuration indication information comprises determining the transmission mode as a frequency division multiplexing (FDM) mode or a space division multiplexing (SDM) mode based on the one or more DMRS port identifiers;
when the configuration indication information comprises the combination of repeated-transmission indication information and transmission configuration indication information, the determining the transmission mode based on the configuration indication information comprises determining the transmission mode as a time division multiplexing (TDM) mode.
