Title
(EN) REPLICATION IN A WIRELESS COMMUNICATION NETWORK
(FR) RÉPLICATION DANS UN RÉSEAU DE COMMUNICATION SANS FIL
Abstract
(EN) A wireless communication device (412) replicates, at a Radio Link Control (RLC) layer of a protocol stack of the wireless communication device (412), an original packet associated to a particular service to provide one or more replicate packets. Each of the one or more replicate packets is a replication of the original packet. For each packet from among a set of packets consisting of the original packet and at least one of the one or more replicate packets, the wireless communication device (412) generates a transport block that comprises the packet and transmits the transport block to one or more base stations or transmission/reception points, TRPs, via a physical layer of the protocol stack of the wireless communication device (412).
(FR) L'invention concerne un dispositif de communication sans fil (412) qui réplique, au niveau d'une couche de commande de liaison radio (RLC) d'une pile de protocoles du dispositif de communication sans fil (412), un paquet d'origine associé à un service particulier pour fournir un ou plusieurs paquets de réplication. Chacun du ou des paquets de réplication est une réplication du paquet d'origine. Pour chaque paquet parmi un ensemble de paquets constitué du paquet d'origine et d'au moins l'un du ou des paquets de réplication, le dispositif de communication sans fil (412) génère un bloc de transport qui comprend le paquet et transmet le bloc de transport à une ou plusieurs stations de base ou points d'émission/réception, TRP, par l'intermédiaire d'une couche physique de la pile de protocoles du dispositif de communication sans fil (412).
