Abstract: According to the present invention, system information in a wireless communication system is transmitted when there is a request from user equipment. A random access channel resource for a system information request is configured. The user equipment can transmit a random access channel by using the random access channel resource when the reception of the system information is needed. A base station can transmit corresponding system information when the random access channel using the random access channel resource configured for the system information request is received.
