RADIO OPERATIONS IN A CARRIER AGGREGATION SYSTEM

摘要

A method comprises, in a carrier aggregation system having multiple component carriers, utilizing an air interface based collision avoidance procedure on at least one component carrier that is associated to a cellular radio access technology to check that a radio resource in the at least one component carrier is available; and thereafter communicating on the radio resource using the cellular radio access technology only if the check reveals that the radio resource is available.
