An approach includes a method implemented in a computer infrastructure having computer executable code tangibly embodied in a computer readable storage medium having programming instructions. The approach further includes the programming instructions configured to collect at least one broadcast control channel allocation list from base stations in a surrounding area. The approach further includes the programming instructions configured to generate a list of power signals which correspond to all broadcast control channel carriers based on the at least one broadcast control channel allocation list. The approach further includes the programming instructions configured to transmit information of a highest carrier power in the list to all virtual base stations in a convoy.
