Downlink control channel indication method, terminal device and network device

Disclosed are a downlink control channel indication method, a terminal device and a network device. The method comprises: a terminal device receiving indication information sent by a network device on a pre-set frequency band of a first time-frequency resource, wherein the first time-frequency resource partially or completely overlaps with a second time-frequency resource; and the terminal device determining the position of a physical downlink control channel (PDCCH) time-frequency resource of the first time-frequency resource according to the indication information. In the technical solution of the present application, the terminal device with the first time-frequency resource can determine the position of the physical downlink control channel (PDCCH) time-frequency resource.
