In UMTS WCDMA a new RACH-based uplink is being discussed. The resources defined for this new E-RACH need to be signalled to the UE. This should avoid disturbing the signalling to existing terminals, i.e. that are not aware of E-RACH. This could be done for E-RACH by repeating the kind of signalling defined for R99 RACH and transmitted on the BCH (Broadcast Control Channel). However, this would imply a significant extra load on the BCH, which is undesirable. The invention is based on the recognition that E-DCH resources can be defined efficiently at least partly with reference to the R99 RACH resources. This can be done in such a way that no additional signalling is required on the BCH.
