Abstract
A terminal device is operative to receive a broadcast message (91) from a cellular network, the broadcast message (91) including at least one bit associated with coverage enhancement, CE, operation of the terminal device. The terminal device is operative to control, when the terminal device is in CE operation, a radio interface to selectively delay, based on the at least one bit included in the broadcast message (91), a CE level dependent repetition of a random access preamble transmission (93, 94).
