Abstract: This application provides an information transmission method. The method includes: determining, by a first network device, a communication type of the first network device in a second time period; and sending, by the first network device, a signal to a second network device in a first time period through an air interface when the communication type is downlink communication or an idle communication type, where the signal is used to indicate the communication type. The second network device may use the received information on the communication type of the first network device in the second time period to determine its communication type in the second time period to minimize interference between the two network devices. For example, if the communication type of the first network device is downlink in the second time period, the second network device may determine its communication type to be downlink in the second time period.

Abstract: A DCI sending method and an apparatus are provided. A base station determines a first channel resource, where the first channel resource is located in the ith time unit of a subframe in a time domain, the subframe includes NT time units, NT is an integer greater than or equal to 2, and i is a positive integer less than or equal to NT; and the base station sends DCI to a terminal device on the first channel resource. In this solution, the first channel resource that carries the DCI is located in the ith time unit of the subframe in the time domain, where i is a positive integer less than or equal to NT. That is, there is a first channel resource in each time unit of the subframe. Therefore, when data needs to be transmitted in any time unit, the data can be transmitted immediately.
