    Abstract: The present invention relates to a radio resource reallocation method based on the circuit mode. In order to efficiently use the radio resource in the packet-based data transmission system, a circuit mode radio resource is reallocated based on a rearrangement information element and a rearrangement counter information element by using the circuit mode. Accordingly, an unused region of the discontinuous radio resource that can be generated by resource de-allocation and resource change can be eliminated, and a resource allocation mismatch that can be generated by a MAP receiving error can be solved.

    Abstract: PURPOSE: A method and apparatus for determining iterative decoding of a decoder are provided to reduce unnecessary repetition by changeably controlling the Iterative decoding operation of a CTC decoder according to radio channel environments. CONSTITUTION: An iterative decoding determination part(24) includes an error count part(241), a comparison part(242), and a repetition determination part(243). The iterative decoding determination part further includes a threshold value setting part(244). The error count part produces errors by comparing second decoding data for hard decision outputted from the first decoder with fourth decoding data for the hard decision outputted from a second decoder. The comparison part compares counted errors with a threshold value. The repetition decision part performs iterative decoding based on a comparison result of the comparison part.
