Abstract

L'invention porte sur un procédé et un dispositif de configuration de signaux de référence de sondage. Le procédé de configuration de signaux de référence de sondage comprend les opérations suivantes : le côté réseau détermine que le côté réception est utilisé pour envoyer des informations de configuration concernant un signal de référence de sondage (SRS) et notifie cela au côté réception. Le côté réception configure le SRS conformément aux informations de configuration reçues concernant le SRS et envoie un signal SRS configuré au côté réseau. Selon la présente invention, au moyen de l'ajout du nombre de symboles et de l'emplacement utilisé pour envoyer un SRS, et d'au moins un élément parmi un drapeau d'activation OCC, la longueur OCC du SRS, l'OCC du SRS et le procédé de mappage d'OCC du SRS dans chaque sous-trame dans les informations de configuration SRS, les ressources temps/fréquence/code utilisées pour envoyer le SRS sont accrues, ce qui résout efficacement le problème d'insuffisance de capacité du SRS dans CoMP scénario 4.
