Des modes de réalisation de la présente invention se rapportent au domaine technique des communications mobiles. L'invention concerne une méthode et un appareil d'ordonnancement d'un spectre partagé. La méthode comprend les étapes suivantes : un BSC reçoit une demande de ressource, envoyée par une cellule GSM, demandant un spectre partagé, la demande de ressource contenant au moins un identifiant de cellule de la cellule GSM ; et détermine, selon la demande de ressource, un spectre partagé qui n'est pas attribué et qui respecte un critère d'interférences de ressource de la cellule GSM, et envoie, à la cellule GSM, des informations d'indication utilisées pour indiquer le spectre partagé en fonction de l'identifiant de cellule, contenu dans la demande de ressource, de la cellule GSM. Dans la présente invention, une demande de ressource envoyée par une cellule GSM est reçue, un spectre partagé qui n'est pas attribué et respecte un critère d'interférences de ressource de la cellule GSM est déterminé en fonction de la demande de ressource reçue, et de plus, des informations d'indication utilisées pour indiquer le spectre partagé sont envoyées à la cellule GSM, pour éviter que le spectre partagé utilisé par la cellule GSM interfère avec un spectre dans une plage aux alentours, ce qui améliore l'efficacité du partage de spectre.
