Abstract
A downlink control information sending method, a downlink control information detection method, and a device are provided. The method includes: receiving, by a terminal device, first signaling, where the first signaling includes configuration information of search space; determining, by the terminal device based on the configuration information, a frequency domain resource or a CCE resource occupied by the search space; and detecting, by the terminal device, downlink control information in the search space. A network device may configure the search space to occupy any frequency domain resource or CCE resource. The terminal device determines, based on the first signaling, the search space configured by the network device, and obtains the downlink control information in a timely manner. This effectively improves data transmission efficiency, and in particular, resolves a problem that downlink control information of duration less than 1 ms cannot be obtained in a timely manner.
