A method of signaling to a mobile terminal the radio resources that will be used in a wireless communication between the mobile terminal and a base station is described. The base station provides a plurality of radio resources. The method comprises the steps: splitting the plurality of radio resources into a set of partitions (124, 126), wherein each partition of the set of partitions comprises a set of virtual blocks (128, . . . , 138), wherein each virtual block of the set of virtual blocks is exclusively mapped to one or more radio resources of the plurality of radio resources; using an identification format (144) according to which a collection of one or more virtual blocks of the set of virtual blocks is identifiable; allocating at least a first virtual block (130, 132) for communication between the mobile terminal and the base station, first block identifier the at least first virtual block being identifiable by a first specification (146) according to the identification format; sending first block identifier the first specification to the mobile terminal.
