Abstract: A terminal scheduling method, a terminal and a base station are provided in the present disclosure, to solve the issue that it is difficult for the base station in the future mobile communication system to flexibly schedule terminal to perform the data transmission on the resources of different carrier interval configurations. The terminal scheduling method includes: sending scheduling information carrying numerology information to a terminal. The base station sends the scheduling information carrying the numerology information to the terminal, and the terminal performs the data transmission on the scheduling resource based on the scheduling information carrying the numerology information, thereby enabling the base station in the future mobile communication system to flexibly schedule the terminal to perform the data transmission on the resources with different numerology information and improving the system performance.
