1. An integrated circuit for controlling a communication apparatus, the integrated circuit comprising:
receiving circuitry, which, in operation, receives system information for the communication apparatus in Coverage Enhancement (CE), the system information including information elements common to a plurality of CE levels including one or more radio condition threshold values used to determine a CE level out of the plurality of CE levels and at least one information element specific to one or more of the plurality of CE levels;
control circuitry, which, in operation, performs soft-combining of the received system information in a plurality of redundancy versions cyclically repeated a defined plurality of times; and
decoding circuitry, which, after each of the soft-combining, attempts to decode the system information,
wherein the receiving circuitry, in operation, receives the information elements common to the plurality of CE levels with a second frequency equal to or lower than a first frequency with which the information elements common to the plurality of CE levels are transmitted, depending on a current CE status of the communication apparatus.
