Abstract
Methods, apparatuses, controllers, systems, and terminals can, in certain embodiments, determine a number and properties of potential interferers in a plurality of available radio channels. The properties of the potential interferers can include modulation methods used by the potential interferers. A network element responsible for channel allocation can perform channel allocation for a terminal and select a modulation method for the allocated channel on the basis of the determination.
