Abstract

La présente invention concerne un procédé et un dispositif d'émission de DRS, un procédé et un dispositif de réception de DRS, une station de base, un équipement d'utilisateur et un support d'enregistrement lisible par ordinateur. Le procédé d'émission de DRS consiste à : émettre un DRS dans une première sous-période d'émission, une période d'émission du DRS comprenant la première sous-période d'émission et une deuxième sous-période d'émission ; et si l'émission du DRS ne réussit pas dans la première sous-période d'émission, émettre le DRS dans la deuxième sous-période d'émission. Dans les modes de réalisation de la présente invention, le DRS est émis dans la première sous-période d'émission, et lorsque l'émission du DRS ne réussit pas dans la première sous-période d'émission, le DRS est émis dans la deuxième sous-période d'émission, de façon à augmenter la possibilité d'émettre le DRS, ce qui permet de pouvoir satisfaire les exigences du réseau, et d'apporter davantage de possibilités d'accès pour l'UE.
