Title
(EN) TRANSMIT METHODS FOR CCFI/PCFICH IN A WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉS DE TRANSMISSION POUR CCFI/PCFICH DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract
(EN)
A method of transmitting a control channel format indicator (CCFI), also known as PCFICH (Physical Control Format Indicator Channel), in case where the length of a coded CCFI is not an integer multiple of three, including mapping a plurality of two-bit CCFI into a codebook with each component codeword having three bits; generating a sequence of codewords selected from the codebook by repeating the selected component codeword for predetermined times; generating a codeword by concatenating the sequence of the selected component codewords with the original CCFI bits; and transmitting the codeword carrying information of CCFI. The method further includes a step of generating a permutation of each of the four codewords by assigning K repetitions of the three-bit component codeword to the number of K resource units respectively and mapping remaining K bits of each of the four codewords separately to the number of K resource units.

L'invention porte sur un procédé de transmission d'un indicateur de format de canal de commande (CCFI), également connu sous le nom de PCFICH (Canal d'Indicateur de Format de Commande Physique), dans le cas où la longueur d'un CCFI codé n'est pas un entier multiple de trois, comprenant le mappage d'une pluralité de CCFI à deux bits en un livre de codes avec chaque mot de code constitutif ayant trois bits; la génération d'une séquence de mots de code sélectionnés à partir du livre de codes par répétition du mot de code constitutif sélectionné pendant un nombre de fois prédéterminé; la génération d'un mot de code par concaténation de la séquence des mots de code constitutifs sélectionnés avec les bits de CCFI originaux; et la transmission du mot de code portant les informations de CCFI. Le procédé comprend en outre une étape de génération d'une permutation de chacun des quatre mots de code par affectation de K répétitions du mot de code constitutif à trois bits au nombre de K unités de ressource respectivement et mappage des K bits restants de chacun des quatre mots de code séparément au nombre de K unités de ressource.
