Abstract: front page image
(EN) Disclosed are a retransmission control method and apparatus in a multi-user shared access (MUSA) process, a UE and a storage medium. The method comprises: allocating an MUSA number for a UE (101); receiving an MUSA data packet sent by the UE in an uplink MUSA resource range indicated by a base station (102); using a multi-user shared access radio network temporary identifier (MUSA-RNTI) to indicate a segment of radio resource block used for transmitting acknowledgement information (103); broadcasting the MUSA number of the UE, the data packet of which is correctly received, in the indicated radio resource block, so that the UE determines, according to the MUSA number, whether to retransmit the MUSA data packet which has been sent (104).
(FR) La présente invention concerne un procédé et un appareil de commande de retransmission dans un procédé d'accès partagé multi-utilisateur (MUSA), un équipement utilisateur (UE) et un support d'informations. Le procédé consiste à : attribuer un nombre MUSA à un UE (101) ; recevoir un paquet de données MUSA envoyé par l'UE dans une plage de ressources MUSA de liaison montante indiquée par une station de base (102) ; utiliser un identifiant temporaire de réseau radio à accès partagé multi-utilisateur (MUSA-RNTI) pour indiquer un segment de bloc de ressources radio utilisé pour transmettre des informations d'accusé de réception (103) ; diffuser le numéro MUSA de l'UE, dont le paquet de données est correctement reçu, dans le bloc de ressources radio indiqué, de sorte que l'UE détermine, selon le nombre MUSA, s'il faut retransmettre ou pas le paquet de données MUSA qui a été envoyé (104).
