Abstract: Methods and apparatus are provided for transmitting downlink control information in mobile communications system. A size of a downlink control information (DCI) format associated with an uplink transmission mode is determined and then compared with a size of a DCI format corresponding to a current downlink transmission mode. If the size of the DCI format associated with the uplink transmission mode is same as the size of the DCI format corresponding to the current downlink transmission mode, a bit is appended to the DCI format associated with the uplink transmission mode to differentiate the size of the DCI format associated with the uplink transmission mode from the size of the DCI format corresponding to the current downlink transmission mode.
