1. A method of transmitting uplink data bursts in a mobile communication system comprising a plurality of mobile terminals, the method comprising:

  • receiving first information indicating correspondence between at least a first communication scheme mobile terminal and information to be transmitted in at least a first uplink data burst and a correspondence between at least a second communication scheme mobile terminal and information to be transmitted in at least a second uplink data burst; and

    transmitting information in the at least a first uplink data burst or the at least a second uplink data burst according to the first information,wherein the at least a first uplink data burst comprises information from both the at least a first communication scheme mobile terminal and the at least a second communication scheme mobile terminal,wherein the at least a second uplink data burst comprises information from only the at least a second communication scheme mobile terminal,wherein a time division multiplexing (TDM) scheme is applied between the at least a first uplink data burst and the at least a second uplink data burst,wherein a first region for the at least a second uplink data burst from only the at least a second communication scheme mobile terminal is immediately followed by a second region for the at least a first uplink data burst from both the at least a first communication scheme mobile terminal and the at least a second communication scheme mobile terminal in an uplink time duration,wherein one ranging channel is transmitted in the uplink time duration, andwherein the one ranging channel is a frequency division multiplexing (FDM) multiplexed with the first region and the second region in the uplink time duration.
