WIRELESS COMMUNICATION SYSTEM, TERMINAL DEVICE, BASE STATION DEVICE, WIRELESS COMMUNICATION METHOD, AND INTEGRATED CIRCUIT

摘要

The present invention configures a terminal device connected to a base station device so as to efficiently receive a random access response message for a random access procedure. On the basis of system information, the terminal device monitors first random access identification information when set in a manner such that the random access response is received via a physical downlink shared channel, monitors second random access identification information when set in a manner such that the random access response is received via a physical downlink control channel, and monitors the first and second random access identification information when set in a manner such that the random access response is received via the physical downlink shared channel and the physical downlink control channel.
