Abstract

Procédé et appareil de transmission de signal d'économie d'énergie. Le procédé fait appel aux étapes suivantes : un terminal recevant un signal d'économie d'énergie, le signal d'économie d'énergie portant au moins des informations parmi des informations d'indication de réveil et des informations d'indication de sommeil de cellule secondaire, les informations d'indication de sommeil de cellule secondaire étant utilisées pour indiquer un comportement de sommeil d'une cellule secondaire ou d'un groupe de sommeil de cellule secondaire appartenant à au moins un groupe de réception discontinue (DRX), et les informations d'indication de réveil étant utilisées pour indiquer un comportement de sommeil de l'au moins un groupe DRX. Par conséquent, dans la mesure où une pluralité de groupes DRX sont configurés pour le terminal en même temps, le groupe DRX indiqué peut être spécifié au moyen d'un signal d'économie d'énergie.
