Patent ID: 8159979

Claim:
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, 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.
