Abrégé
(EN)

The invention relates to an apparatus including at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code con-figured to, with the at least one processor, cause the apparatus at least to: search for feasible component carriers by measurements, and if at least one feasible component carrier is found, take it into use; select at least one home node for negotiations for obtaining resources, the selection being based on the measurements, and negotiate for obtaining resources, if no feasible component carriers are found; take into use at least one feasible component carrier obtained based on the negotiations, if at least one feasible component carrier is obtained; and take into use at least one component carrier which is closest feasible, if no feasible component carriers are obtained.
