There is provided a device and method for transmitting packet data in a mobile communication system.
A sub-code generator generates a plurality of sub-codes with the same of different code rates for the
input of a PLP (Physical Layer Packet) information bit stream. A Controller determines a minimum
data rate by which the number of the modulation symbols of a sub-code generated by a predetermined
modulation method is equal to or greater than the number of transmittable modulation symbols for each
time period. A symbol pruner prunes part of the modulation symbols of the sub-code equal to the
number of transmittable modulation symbols for the time period, if the number of the modulation
symbols of the sub-code is greater than the number of transmittable modulation symbols for the time
period.
