A time-frequency resource preemption determining method includes: receiving and reading first service data sent by the base station; if it is determined that the first service data fails to be received, reading second service scheduling control data in a set time period and in a set frequency range according to a time-frequency resource occupied by the first service data that fails to be received; and if the second service scheduling control data is read, and it is determined according to scheduling information carried in the second service scheduling control data that a time-frequency resource area occupied by the scheduled second service data covers a time-frequency resource area occupied by the first service data that fails to be received, determining that the second service data preempts the time-frequency resource of the first service data. As such, the situation of time-frequency resource preemption between service data can be determined.
