Provided are a method for reporting user equipment auxiliary information, user equipment and a base station. The method comprises: if the configuration in user equipment (UE) for disabling the transmission of UE auxiliary information has not been started or has been closed, the UE transmitting the UE auxiliary information to a base station; or if the configuration in the UE for enabling the transmission of UE auxiliary information has been started, the UE transmitting the UE auxiliary information to the base station. The above method will not cause an increase of air interface signalling overheads, and at the same time, allows a base station to better optimize the performance of UE according to UE auxiliary information.
