1. method that is used for shrinking code element in communication system, this method comprises:

  • Reception will be suitable for S code element of a frame, and this frame has the capacity of N code element, and wherein S is greater than N;

    Determine from S the code element that is received, to shrink the code element number P that falls, make the not code element of contraction of remainder be suitable for this frame;

    Calculate a plurality of contraction space D 1 to DN according to code element number S that is received and code element contraction number P;

    Determine and will shrink number, wherein will carry out P1 to PN code element and shrink to shrink space D 1 to DN respectively each code element of carrying out in described a plurality of contraction space D 1 to DN, and wherein P1'"'"'s to PN and equal P;

    AndCarry out P1 to PN code element contraction to shrink space D 1 to DN respectively.
