WIPO Patent Application WO/2017/129035

A1

Disclosed in the present invention are a method and apparatus for transmitting and detecting downlink control information. The method comprises: determining a state of resource allocation in a downlink transmission time period, the resource allocation comprising allocation of at least one downlink transmission resource region; and transmitting downlink control information on a preset resource in the at least one downlink transmission resource region, the downlink control information being used for scheduling at least one terminal to perform data transmission in the downlink transmission resource region. The method also comprises: detecting the downlink control information on the preset resource in the downlink transmission time period; determining, according to the detected downlink control information, a data transmission region indicated by the downlink control information; and detecting follow-up downlink control information according to the data transmission region. By using the present invention, downlink control information can be transmitted at a fixed position in each downlink transmission time period, and multiple transmission time intervals of different lengths are supported, so that rich service types in the future can be better supported.
