Communication method, terminal and base station

The invention discloses a communication method. The communication method comprises steps that, a system information block message sent by a base station is received by a terminal, and the system information block message comprises parameter information used for selecting a relay terminal, whether the terminal satisfies conditions for being the relay terminal is determined by the terminal itself according to the parameter information; if the terminal satisfies the conditions for being the relay terminal, capability information of the terminal is reported to the base station, so the relay terminal is selected from various terminals by the base station according to the capability information reported by the various terminals within a signal coverage scope for communication. The invention further discloses the terminal and the base station. Through the method, the terminal can be initialized to be the relay terminal for relay communication.
