A communication method for a terminal is disclosed, including creating a radio link failure (rlf)-report including information associated with an rlf with a first base station; connecting to one base station from among base stations including the first base station; and transmitting the rlf-report to the one base station. Furthermore, a communication method for a base station is also disclosed, including connecting to the terminal; and receiving an rlf-report including information associated with a previous rlf between the terminal and another base station. In an aspect, information including channel information is transmitted to a base station to which a terminal is initially connected even when the terminal has failed in performing random access thereto, to thus enable the efficient transmission of information, and the base station may control scheduling or the like in accordance with the information reported by the terminal, thereby enabling efficient communication.
