A UE needing to use coverage extension to request access to a prospective serving cell detects cells (other than the prospective serving cell) on its frequency, and then investigates each such cell (for example, by attempting to read its system information block and, if the system information block can be read, determining if the cell supports access using coverage extension. If detected cells do not support coverage extension, the UE does not use coverage extension techniques to request access, but if all detected cells support coverage extension, the UE requests access using coverage extension techniques.
