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.

5. 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 a first uplink data burst; receiving second information indicating correspondence between at least a second communication scheme mobile terminal and information to be transmitted in a second uplink data burst; and transmitting information in either the first uplink data burst or the second uplink data burst according to the first information or the second information, wherein the 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 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 first uplink data burst and the second uplink data burst, wherein a first region for the second uplink data burst from only the at least a second communication scheme mobile terminal is immediately followed by a second region for the first uplink data burst from the at least a first communication scheme mobile terminal and the at least a second communication mobile terminal in an uplink time duration, wherein one ranging channel is transmitted in the uplink time duration, and wherein the one ranging channel is a frequency division multiplexing (FDM) multiplexed with the first region and the second region in the uplink time duration. - View Dependent Claims (6, 7, 8)
