Claim:
1. An apparatus comprising: at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: search for feasible component carriers by measuring interference on selected component carriers, and in response to finding at least one feasible component carrier whose interference is below a set threshold according to Quality of Service requirements, take it into use; in response to finding more than one feasible component carrier, take one of the feasible component carriers into use and include the others into a backup list; select at least one home node for carrying out negotiations for obtaining at least one feasible component carrier, the selection being based on the measurements, and carry out negotiations between the selected node and a neighboring home node for obtaining at least one feasible component carrier, in response to failure to find any feasible component carriers in the search, wherein negotiations for obtaining at least one feasible component carrier comprise a request to release a feasible component carrier currently in use so as to make that component carrier available for the at least one home node; in response to obtaining at least one feasible component carrier based on the negotiations, take into use the at least one feasible component carrier; and in response to failure to obtain any feasible component carriers, take into use the component carrier experiencing the lowest interference.
