Abstract
(EN)
Provided are a contention random access method and apparatus. The method comprises: a terminal side device sends an Msg1 message corresponding to a two-step contention random access to a network side device; the terminal side device receives an Msg2 message returned by the network side device, and if the terminal side device determines two-step contention random access failure according to the reception condition of the Msg2 message, the terminal side device performs two-step contention random access failure processing, the Msg2 message being determined by the network side device according to the reception condition of the Msg1 message received by the network side device.
(FR)
L'invention concerne un procédé et un appareil d'accès aléatoire de contention. Le procédé comprend les étapes suivantes : un dispositif côté terminal envoie un message Msg1 correspondant à un accès aléatoire de contention en deux étapes à un dispositif côté réseau ; le dispositif côté terminal reçoit un message Msg2 renvoyé par le dispositif côté réseau, et si le dispositif côté terminal détermine une défaillance d'accès aléatoire de contention en deux étapes selon l'état de réception du message Msg2, le dispositif côté terminal effectue un traitement de défaillance d'accès aléatoire de contention en deux étapes, le message Msg2 étant déterminé par le dispositif côté réseau selon l'état de réception du message Msg1 reçu par le dispositif côté réseau.
