The method includes: determining, by a base station, a configuration of a time-frequency resource unit from at least two configurations of a time-frequency resource unit of a control channel; and sending, by the base station, indication information to a terminal device, where the indication information is used to indicate the configuration of the time-frequency resource unit, and the at least two configurations of a time-frequency resource unit include a first configuration and a second configuration. In the embodiments of this application, the base station can flexibly configure the time-frequency resource unit of the control channel. In addition, flexibly configuring a time-frequency resource unit can reduce a probability that time-frequency resource units of different structures are blocked, thereby reducing complexity of detecting the control channel by the terminal device.

Abstract: Disclosed are methods and systems for determining, by a terminal device, downlink control information that includes a first information field and a second information field. The first information field is used to indicate whether to switch an active bandwidth part of a terminal device. When the first information field indicates to switch the active bandwidth part of the terminal device, the second information field is used to indicate one or more active bandwidth parts and frequency domain resource location of a data channel in the active bandwidth parts to switch; or when the first information field indicates not to switch the active bandwidth part of the terminal device, the second information field is used to indicate a frequency domain resource location of a data channel in a currently accessed active bandwidth part. A working bandwidth part of the terminal device can be indicated, and resource utilisation is improved.
