Abstract: PROBLEM TO BE SOLVED: To provide techniques for dynamically mapping assigned resources to physical resources.SOLUTION: A resource assigned for communication may be mapped to a first physical resource on the basis of a first mapping function and to a second physical resource on the basis of a second mapping function. The assigned resource may be configurable for hopping or no hopping. The first mapping function may be a transparent function or may map consecutive input indices to non-consecutive output indices. The second mapping function may be equal to an output of the first mapping function plus an offset defined by a step size and a hop value. The hop value may be configurable for the assigned resource and may be conveyed in a resource assignment. The hop value may be set to a first value to indicate no hopping or to a second value to indicate hopping by the step size.
