Abstract:
(EN) It is provided a method, comprising generating an ordered sequence of U check bits for an ordered sequence of K information bits by a CRC algorithm based on a polynomial; determining d determined groups among D groups, wherein each of the D groups has a respective group index g, each of the D groups consists of at least one of the K information bits and a respective one of the U check bits; arranging the K information bits and the U check bits into a code block, wherein for each of the d determined groups, the respective information bits and the respective check bit are arranged at the code block positions not later than the code block position K or K+d; the polynomial consists of an outer bit sequence directly followed by D-1 bits having a value of 0 directly followed by the outer bit sequence.
(FR) Cette invention concerne un procédé, comprenant : la génération d'une séquence ordonnée de U bits de contrôle pour une séquence ordonnée de K bits d'information par un algorithme CRC sur la base d'un polynôme; la détermination de d groupes déterminés parmi D groupes, chacun des D groupes ayant un indice de groupe g respectif, chacun des D groupes étant constitué d'au moins l'un des K bits d'information et d'un bit respectif parmi les U bits de contrôle; l'agencement des K bits d'information et des U bits de contrôle en un bloc de code, où pour chacun des d groupes déterminés, les bits d'information respectifs et le bit de contrôle respectif sont agencés dans les positions de bloc de code pas plus tard que la position de bloc de code K ou K+d; le polynôme est constitué d'une séquence de bits externe suivie directement de D-1 bits ayant une valeur de 0 directement suivis par la séquence de bits externe.
