Abstract
Embodiments of the present application provide a method and apparatus for transmitting downlink control information (DCI), for solving the technical problem that neither the existing protocol nor the communication system has a method for encoding sounding reference signal resource indication (SRI) and pre-coding matrix indication (TPMI) or rank indication (TRI) information. The method comprises: a network device determines the number of candidate values of preset indication information borne by a preset indication field in the downlink control information (DCI), the preset indication information comprising one of or a combination of two of the sounding reference signal resource indication (SRI) and pre-coding matrix indication (TPMI) or rank indication (TRI) information; the network device determines the length of the preset indication field according to the number of candidate values of the preset indication information, and encodes the preset indication information according to the length to generate the DCI; and the network device sends the DCI to the UE.
