Abstract: The present application relates to the technical field of communications, and provides a transmission method and apparatus. The method comprises: a network side device 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 equal to 1; the network side device determines, according to the number of the DMRS port groups occupied by the downlink transmission data, a code word transmission mode corresponding to the downlink transmission data; and the network side device performs data processing on the downlink transmission data according to the code word transmission mode, and transmits the processed downlink transmission data by means of transmission points corresponding to the N DMRS port groups. By determining, by means of the number of DMRS port groups actually occupied by a data channel, whether to use single code word transmission or double code word transmission, a more flexible method for determining a code word transmission mode is implemented.

Abstract: Disclosed in embodiments of the present application are a method and device for scheduling transmission, which are used to solve the problem in which there are currently no solutions for transmission scheduling that supports various communication scenario changes. In the embodiments of the present application, a network side device sends a transmission instruction to a terminal device; and the terminal device determines a transmission scheduling mode according to the transmission instruction and performs transmission scheduling. Moreover, after determining that an adjustment condition is satisfied, the network side device determines a new transmission scheduling mode and notifies the terminal device, so that the terminal device performs transmission scheduling by means of the new transmission scheduling mode. In the described method, the network side device may adjust the transmission scheduling mode after determining that the current transmission scheduling mode satisfies the adjustment condition, and then notify the terminal device, so that the terminal device adjusts the transmission scheduling mode, which better ensures the transmission performance and reliability of a system, and achieves dynamic switching between multiple transmission modes.
