The present application relates to the field of mobile communications. Disclosed are an information sending method and apparatus, and a terminal and a storage medium. The method comprises: a first terminal determining a time range, determining a resource set according to the time range, and sending the resource set to a second terminal in a target time unit, wherein the resource set is used to assist the second terminal with resource selection. In the present application, a first terminal determines a rational time range, and determines, on the basis of the time range, a resource set suitable for the first terminal or not suitable for the first terminal, thereby ensuring that there are no invalid resources in resources sent to a second terminal or that the number of invalid resources is reduced. When the first terminal uses a DRX mechanism, cooperation between the first terminal and the second terminal can be better implemented.
