Title (EN) METHOD AND APPARATUS FOR PILOT SIGNAL TRANSMISSION
(FR) PROCEDE ET DISPOSITIF DE TRANSMISSION DE SIGNAL PILOTE
Abstract: front page image
(EN)A method and apparatus for pilot signal transmission is disclosed herein. In particular, a pilot transmission scheme is utilized where pilot sub-carrier bandwidth differs from data sub-carrier bandwidth. Because some user's data sub-carriers will no longer have the user's pilot sub-carriers adjacent to them, the set, or pattern of sub-carriers used by the pilot blocks changes at least once in a burst. Changing the pilot block pattern (the set of occupied pilot block sub-carriers) at least once in the burst serves to increase the frequency proximity of occupied data sub-carriers to occupied pilot sub-carriers in the burst.
(FR)L'invention concerne un procédé et un dispositif de transmission de signal pilote. Un schéma de transmission pilote est notamment utilisé, une bande passante de sous-porteuse pilote différant d'une bande passante de sous-porteuse de données. Comme certaines sous-porteuses de données ne sont plus adjacentes aux sous-porteuses pilote, l'ensemble ou le motif de sous-porteuses utilisé par les blocs pilote change au moins une fois dans une rafale. La modification du motif de bloc pilote (l'ensemble de sous-porteuses de blocs pilote occupées) dans la rafale sert à augmenter la proximité de fréquence de sous-porteuses de données occupées par rapport aux sous-porteuses pilote dans la rafale.
