1. A packet transmission method of a base station in a communication system, the method comprising:

  • receiving a random access preamble message from a terminal;

    transmitting a random access response message including information associated with a radio resource control (RRC) connection, to the terminal;

    receiving a connection request message generated based on the information from the terminal;

    transmitting a connection response message in response to the connection request message to the terminal;

    determining whether a connection complete message is received from the terminal to avoid losing the connection response message;

    retransmitting, if the connection complete message is not received, the connection response message to the terminal, periodically until the connection complete message is received, by controlling transmission power of the connection response message, wherein retransmitting the connection response message comprises triggering, at one of an RRC entity and a Radio Link Control (RLC) entity, retransmission of the connection response message; and

    establishing, if the connection complete message is received from the terminal, a connection between the base station and the terminal, wherein the base station comprises the RRC entity and the RLC entity.
