Patent ID: 8279887

Claim:
A method of selecting radio resources for transmission of data over a radio link to which a set of resource units comprising at least two resource units have been allocated, the method comprising: identifying a most favourable received coded bit information rate; setting a lower boundary of an acceptable range for received coded bit information rates to a value obtained by subtracting, from the most favourable received coded bit information rate, a term defining an acceptable difference from the most favourable received coded bit information rate; determining, for each of one or more resource units (j), a respective received coded bit information rate (RBIR j ) based on a modulated symbol-level mutual information value (I j ) associated with that resource unit and a modulation order (M j ) associated with that resource unit, such that RBIR j =I j /M j ; checking whether the respective received coded bit information rate of one or more resource units falls within the acceptable range; and selecting at least one resource unit out of the set of resource units, wherein the selecting is performed in dependence on whether the respective received coded bit information rate for the selected resource unit falls within the acceptable range.
