Abstract
The invention provides a scheduling method for terminal equipment. The method comprises the following steps that a notice that the terminal equipment has interference at an adjacent frequency band of the frequency band for receiving downlink data is sent to a base station when the terminal equipment determines that a difference between the total intensity of currently-received signals and the average signal intensity in the preset time is greater than a first threshold, so that when the base station schedules the terminal equipment at the next time, the terminal equipment is scheduled to receive the downlink data on a frequency band, wherein the distance between the frequency band and the adjacent frequency band is greater than a second threshold. The invention also provides a terminal scheduling device based on the same inventive concept, so that the interference between the adjacent-band terminals can be avoided.
