Abstract: Embodiments of this application provide a reconfiguration method, a terminal device, and a communications system. The method includes: A terminal device sends a first capability report message when requesting to attach to a first cell. When a reconfiguration request message is received for N consecutive times and all reconfigurations fail, the terminal device detaches from the first cell, where the reconfiguration request message is used to indicate, to the terminal device, a frequency of a secondary cell in which carrier aggregation is performed, and N is a positive integer. The terminal device sends a second capability report message when re-requesting to attach to the first cell, and carrier aggregation capabilities of the terminal device are disabled.
