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

Abstract: A method, base station, terminal and communication system for selecting a component carrier. The method includes: determining the coverage range of each available carrier which can be used by the terminal; determining whether the distribution of the coverage ranges of all available carriers accords with a preset distribution mode; and in the case of according with the presetting distribution mode, at least according to a rule which is determined by the distribution mode, determining a component carrier to be used. With the embodiments, a component carrier used by the terminal can be reasonably chosen.
