Abstract
(EN)
Provided are a method and device for random access, which can implement flexible random access. The method comprises: a first device determining a first basic parameter set used by a first message transmitted in a random access process; and the first device, using the first basic parameter set, sending the first message to a second device, or the first device receiving the first message sent by the second device.
(FR)
L'invention concerne un procédé et un dispositif d'accès aléatoire, aptes à mettre en œuvre un accès aléatoire flexible. Le procédé comprend les étapes suivantes : un premier dispositif détermine un premier ensemble de paramètres de base utilisé par un premier message transmis durant une procédure d'accès aléatoire; et, à l'aide du premier ensemble de paramètres de base, le premier dispositif envoie le premier message à un second dispositif, ou bien le premier dispositif reçoit le premier message envoyé par le second dispositif.
