Abstract
(EN)
A method and system for using a Sounding channel are disclosed by the present invention, wherein the method includes: setting data information and a Sounding sequence, wherein the data information includes user data and/or pilot frequency data; and transmitting the data information on the sub-carrier on which the Sounding sequence is transmitted. The present invention solves the problem that channel transmission efficiency is lower due to the transmission method of the Sounding sequence in the prior art, and improves transmission efficiency.
(FR)
La présente invention porte sur un procédé et un système d'utilisation d'un canal de sondage, le procédé consistant à : régler des informations de données et une séquence de sondage, les informations de données comprenant des données utilisateur et/ou des données de fréquence pilote; et transmettre les informations de données sur la sous-porteuse sur laquelle la séquence de sondage est transmise. La présente invention résout le problème selon lequel l'efficacité de transmission de canal est plus faible en raison du procédé de transmission de la séquence de sondage dans l'état antérieur de la technique, et améliore l'efficacité de transmission.
