The present invention relates to a method and device for activating and de-activating the uplink of a secondary cell of a terminal. The method for activating the uplink of a secondary cell of a terminal comprises: determining the number of component carrier waves the RF chain of the terminal can simultaneously receive; determining the activation method to be used for uplink activation based on the number of component carrier waves; and, based on needs, sending information that carries the activation method. Using this invention, one can determine the uplink activation or de-activation method based on the number of component carrier waves the terminal's RF chain can simultaneously receive, thus conserving the electricity consumption of the terminal and avoiding communication interruptions. |
