Abstract: The present invention discloses a method for receiving scheduling information, comprising steps of: receiving Downlink Control Information (DCI); and determining, according to a mapping relationship between configured transmission resources used for a Physical Uplink Shared Channel (PUSCH) and scheduling information in the DCI, scheduling information corresponding to the PUSCH in the DCI. Compared with the prior art, in the present invention, the scheduling information in the DCI is determined by the mapping relationship between the configured transmission resources used for transmitting the PUSCH by a UE and the scheduling information in the DCI, so that a base station can schedule all UEs for which there is a mapping relationship between PUSCH configured transmission resources and the scheduling information in DCI by sending only one piece of DCI. The scheduling overhead is reduced, the resource waste is reduced, and the efficiency of scheduling terminals by a communication system is significantly improved.
