Document Type and Number:
WIPO Patent Application WO/2010/078801
Kind Code:
A1
Abstract:
A method for subband/miniband resources permutation and a method for subcarrier/subcarrier group permutation are disclosed by the present invention. The method for subband/miniband resources permutation includes: the number of columns of a matrix is determined according to the number of subbands/minibands which need to be permutated and the number of rows of the matrix, or, the number of rows of the matrix is determined according to the number of subbands/minibands which need to be permutated and the number of columns of the matrix; the labels of subbands/minibands which need to be permutated are written into the matrix in turn according to a first predetermined sequence, the remnant elements of the matrix are filled with blanks after all labels of subbands/minibands which need to be permutated have been written into the matrix; the written labels are read in turn from the matrix according to a second predetermined sequence and the blanks are skipped, and the labels read in turn are regard as permutation table to perform the subsequent permutation. The present invention avoids the problem that the memory space is waste due to storage of the primitive root lists and the problem that the permutation sequence can not be generated because of incalculable Reed Solomon (RS) code, and the permutation mode is effectively improved.
