Disclosed are a method and apparatus for transmitting a time-discontinuous burst pilot channel being dependent on transmission data in a mobile communication system. In the apparatus, a modulator generates a modulated pilot symbol by outputting an input pilot symbol at a designated at least one of phase and on a designated complex channel according to an information bit for determining at least one of the phase and/or the complex channel, and a spreader spreads the modulated pilot symbol from the modulator with an orthogonal code selected among a plurality of orthogonal codes. The burst pilot channel transmits side information being dependent on the transmission data according to the phase, and/or the complex channel and the orthogonal code.

La présente invention concerne un procédé un et dispositif d'émission de canal pilote en mode rafales en discontinuité temporelle en fonction de données d'émission dans un système de communications mobiles. Dans l'appareil, un modulateur génère un symbole pilote modulé par production en sortie d'un symbole pilote d'entrée à l'une au moins des phases désignées et sur un canal complexe désigné en fonction d'un bit d'information pour déterminer l'un au moins de la phase et/ou du canal complexe, et l'étaleur étale le symbole pilote modulé provenant du modulateur avec un code orthogonal sélectionné parmi une pluralité de codes orthogonaux. Le canal pilote en mode rafales émet une information latérale en fonction de données démission en tenant compte de la phase et/ou du canal complexe ainsi que du code orthogonal.
