A number of techniques are described for signalling the allocation of resources within a communications system. A preferred method that is described includes the steps of: receiving an allocation of sub-carriers for a user device, the allocation comprising data defining a starting block and data defining a number of consecutive blocks from the starting block; a first mapping step of mapping the data defining the number of consecutive blocks from the starting block to a first mapped value in accordance with first mapping data; a second mapping step of mapping the data defining the starting block and said first mapped value to a second mapped value representative of the allocation in accordance with second mapping data; and signalling said second mapped value as resource allocation data to the user device.
