Le procédé de transmission de signal décrit dans la présente invention comprend les étapes suivantes : d'après la relation correspondante entre de premières informations de configuration de signal en liaison montante et un élément de service supporté par une petite cellule MBMS actuelle, quand un UE demande ledit élément de service, l'UE détermine les premières informations de configuration de signal en liaison montante, l'élément de service comprenant un service, un ensemble de services comprenant au moins deux services, ou un système de services supportant au moins un service ; et, d'après les premières informations de configuration de signal en liaison montante, l'UE envoie un premier signal en liaison montante. Comme l'UE peut demander l'élément de service sur le côté réseau sans qu'il soit nécessaire d'envoyer une demande d'accès aléatoire au côté réseau, une congestion d'accès et une aggravation d'une interférence de signal en liaison montante et en liaison descendante peuvent être évitées.
