The present disclosure relates to an information transmitting method and apparatus, a demodulating method and apparatus for a semi-persistent scheduling scheduling unit, a base station, a user equipment, and a computer readable storage medium. The information sending method includes: adding, by using the control unit, the information element IE in the radio resource control RRC signaling configured for the semi-persistent scheduling SPS scheduling, where the IE is used to indicate the reference to the number of candidate positions of the SPS scheduling unit of the user equipment UE. a value; transmitting, to the UE, RRC signaling carrying a reference value of the number of candidate locations and period information of the SPS scheduling unit. In this embodiment, the RRC signaling carryingthe reference value of the candidate location number and the periodic information of the SPS scheduling unit is sent to the UE, so that the UE can determine the number of candidate locations accordingto the received RRC signaling, and receive the SPS scheduling at the candidate location. Units to reduce the number of times the base station dispatches to the SPS scheduling unit, thereby reducing wasted common control channel resources.
