Abstract

L'invention concerne un procédé et un appareil d'interrogation d'informations de capacité, qui peuvent être appliqués dans un système de communication. Le procédé comprend les étapes suivantes : une station de base envoie des premières informations d'indication à d'autres dispositifs réseau pour demander les informations de capacité d'un dispositif terminal, la station de base étant capable d'indiquer une plage de capacité du dispositif terminal requis ; et reçoit des premières informations de capacité provenant des autres dispositifs réseau, les premières informations de capacité comprenant les informations de capacité du dispositif terminal. Par exemple, les premières informations de capacité comprennent des informations de capacité de commutation de signal de référence de sondage de canal (SRS) du dispositif terminal. Au moyen du procédé d'interrogation d'informations de capacité de l'invention, la station de base peut demander les informations de capacité du dispositif terminal requis de manière flexible, et l'efficacité de transmission des informations de capacité entre la station de base et les autres dispositifs réseau est améliorée.
