1. A method, by a node in a mobile communication network, of controlling aggregation of component carriers from a first spectrum that is assigned to the mobile communication network and a second spectrum that is not assigned to the mobile communication network, the method comprising:

  • allocating at least one component carrier from the second spectrum to a group of mobile terminals that are using component carriers from the first spectrum and that are allowed to use component carriers from the second spectrum; and

    in response to detecting that a primary user of the second spectrum requires usage of the at least one component carrier from the second spectrum, transmitting a group message on at least one component carrier from the first spectrum to the group of mobile terminals that are allowed to use the component carriers from the second spectrum, wherein the at least one component carrier from the second spectrum is already allocated to the group of mobile terminals that are using the component carriers from the first spectrum and that are allowed to use the component carriers from the second spectrum, andwherein said group message controls operation of the mobile terminals of the group of mobile terminals that are allowed to use the component carriers from the second spectrum to deactivate the usage of the at least one component carrier from the second spectrum.
