FIELD: radio engineering, communication.
SUBSTANCE: method comprises: generating, by the network side, the downlink control information (DCI) for the terminal. The control bits in the DCI format do not include a transmission unit to the code word "swap flag" control bit in the case where the network side for the terminal has preconfigured the demodulation reference signal used for demodulating the data, and the control bits in the DCI format include a the transmission unit to the code word "swap flag" control bit in the case where the network side for the terminal has not preconfigured the demodulation reference signal used to demodulate the data; and sending, the network side generated by the DCI terminal.
EFFECT: increase the efficiency of using the overhead required to transmit control information.
