The present invention relates to radio telecommunication, and discloses a method for releasing reserved resources. The method includes: utilizing the control signaling or control signaling format 1A with minimum overhead in the downlink scheduling control signalings supported by the user in a Long Term Evolution (LTE) system as the control signaling for releasing reserved resources. An apparatus and a base station for releasing reserved resources are disclosed in an embodiment of the present invention. Through the method, the apparatus, and the base station for releasing reserved resources disclosed herein, the Physical Downlink Control Channel (PDCCH) resources are saved, and transmission performance of the control signaling for releasing reserved resources is improved.
