Abstract
(EN)
The present invention relates to a method and apparatus for sending a synchronization signal. The method comprises: measuring the signal intensity of a received communication signal; according to the signal intensity of the communication signal, determining a target configuration parameter for sending a synchronization signal; and sending the synchronization signal by using the target configuration parameter. In the technical solution, by means of analyzing the signal intensity of a received communication signal, a target configuration parameter for sending a synchronization signal is automatically determined, so as to realize the supply of differentiated synchronization signal sending resources to a scenario covering signals of different intensities, thereby being able to improve the synchronization effect of a user equipment within a weak coverage area, increase the utilization rate of radio resources and enhance the user experience.

La présente invention concerne un procédé et un appareil d'envoi d'un signal de synchronisation. Le procédé consiste à : mesurer l'intensité de signal d'un signal de communication reçu ; selon l'intensité de signal du signal de communication, déterminer un paramètre de configuration cible pour envoyer un signal de synchronisation ; et envoyer le signal de synchronisation en utilisant le paramètre de configuration cible. Dans la solution technique, au moyen de l'analyse de l'intensité de signal d'un signal de communication reçu, un paramètre de configuration cible pour envoyer un signal de synchronisation est déterminé automatiquement, de façon à réaliser la fourniture de ressources d'envoi de signal de synchronisation différencié à un scénario portant sur des signaux d'intensités différentes, ce qui permet d'améliorer l'effet de synchronisation d'un équipement d'utilisateur dans une zone de faible couverture, d'augmenter le taux d'utilisation de ressources radio et d'améliorer l'expérience d'utilisateur.
