Both the MBMS dedicated cell and the MBMS/unicast hybrid cell can adopt the MBSFN transmission mode. In addition, if advanced terminal receiver technology is used, the time difference of multipath propagation can be solved, thereby eliminating intra-cell interference. The diversity effect brought by this multi-cell co-frequency transmission can also be solved. Issues such as coverage of blind spots, enhance the reliability of reception, and improve coverage.

Abstract

L'invention concerne un procédé et un appareil permettant de rapporter un état de réception de service MBMS. En appliquant les solutions techniques des modes de réalisation selon la présente invention, des stations de base peuvent informer en temps utile un MCE d'un état de réception de service MBMS d'un terminal, afin que le MCE puisse déterminer s'il faut changer de ressources selon l'état de réception actuel. De cette manière, il est garanti que les ressources MBSFN d'interface radio du système sont utilisées de façon optimale.
