Title
(EN) METHOD FOR TRANSMITTING CODEWORD
(FR) PROCÉDÉ DE TRANSMISSION DE MOT CODÉ
Abstract
(EN)
A method for transmitting a codeword through a subchannel consisting of a plurality of tiles in a wireless communication system in which one tile comprises a plurality of data subcarriers and at least one pilot subcarrier is provided. The method includes generating a codeword by assigning pilot symbols to the at least one pilot subcarrier in each tile, by assigning a first codeword symbol to some of the plurality of data subcarriers, and by assigning a second codeword symbol to the remaining data subcarriers, the codeword corresponding to the plurality of tiles, and transmitting the codeword. Resources on a frequency-time axis can be effectively used for transmitting various data or control information.
(FR)
La présente invention concerne un procédé permettant de transmettre un mot codé par le biais d'un sous-canal composé d'une pluralité de pavés dans un système de communication sans fil dans lequel un pavé comprend une pluralité de sous-porteuses de données et au moins une sous-porteuse pilote. Le procédé comprend la génération de mot codé en attribuant des symboles pilotes à la sous-porteuse pilote dans chaque pavé au moins, en attribuant un premier symbole de mot codé à certaines sous-porteuses de données parmi la pluralité et en attribuant un second symbole de mot codé aux sous-porteuses de données restantes, le mot codé correspondant à la pluralité de pavés, et en transmettant le mot codé. Des ressources sur un axe fréquence-temps peuvent être efficacement utilisées pour transmettre diverses données ou informations de commande.
