Abstract
In accordance with an example embodiment of the present invention, there is at least a method, apparatus, and computer program product to perform an over-provisioning of a radio resource including a periodic channel quality indicator resource in a predetermined way, and an allocating of the radio resource in such a manner that at least one of an effective system bandwidth is reduced and out-of-band emissions related to the allocated radio resource are taken into account.
