CA 2707744

A method for sending, transmitting and scheduling a system message in a long term evolution system is disclosed, said sending method includes the following steps: when a base station sends the system message, it takes a radio frame with which system frame number is SFN-M as a radio frame in which a master system information block (MIB) is sent for the first time in the repeat cycle of the master system information block, and sends a scheduling information unit SU-1 in a fixed sub-frame of the radio frame with which system frame number is SFN-S1; wherein, the SFN-M is divisible by 4 and the SFN-S1 is divisible by 8. According to the technical scheme of the present invention, by fixing the relative scheduling relationship between the SU-1 and the MIB, the scheduling information bit related to the SU-1 can be omitted in the MIB, thus under the same sending condition, the coverage of the MIB can be increased and the reliability that the user equipment receives the MIB can be improved.

L'invention porte sur un procédé pour envoyer, transmettre et planifier un message système dans un système d'évolution à long terme, ledit procédé d'envoi comprenant les étapes suivantes : lorsqu'une station de base envoie un message système, elle prend une trame sans fil avec laquelle un numéro de trame système est SFN-M en tant que trame sans fil dans laquelle un bloc de message système principal MIB est envoyé pour la première fois dans la période de répétition du message système principal et envoie un bloc d'informations de planification SU-1 dans une sous-trame fixe d'une trame sans fil avec laquelle le numéro de trame système est SFN-S1. Dans cela, le reste de division de SFN-M par 4 est 0, le reste de division de SFN-S1 par 8 est 0. Le schéma technique de la présente invention peut omettre un bit d'informations de planification concernant SU-1 dans MIB par fixation de la relation de planification relative entre SU-1 et MIB. Dans la même condition d'envoi, le schéma de la présente invention peut augmenter la couverture de MIB et la fiabilité de réception de MIB.
