摘要：The present application relates to the technical field of communications, andprovides a transmission method and apparatus. The method comprises: a network sidedevice determines a number of Demodulation Reference Signal (DMRS) port groups N

occupied by downlink transmission data sent to a terminal, N being greater than or equalto 1; the network side device determines, according to the number of the DMRS portgroups occupied by the downlink transmission data, a code word transmission modecorresponding to the downlink transmission data; and the network side device performsdata processing on the downlink transmission data according to the code word

transmission mode, and transmits the processed downlink transmission data by means oftransmission points corresponding to the N DMRS port groups. By determining, bymeans of the number of DMRS port groups actually occupied by a data channel, whetherto use single code word transmission or double code word transmission, a more flexiblemethod for determining a code word transmission mode is implemented.
