Abstract: L'invention concerne des procédés, des systèmes et des dispositifs de communication sans fil. Un dispositif sans fil peut être configuré pour communiquer avec un noeud maître et un noeud secondaire. En cas de défaillance d'un groupe de cellules maîtresses associé au noeud maître, le dispositif sans fil peut lancer ou mettre en oeuvre une procédure de reprise du groupe de cellules maîtresses. La procédure de reprise du groupe de cellules maîtresses peut consister à utiliser une porteuse radio de signalisation secondaire pour transmettre des informations de défaillance relatives à la défaillance du groupe de cellules maîtresses lorsqu'une porteuse radio de signalisation divisée n'est pas configurée. Le noeud secondaire peut relayer les informations de défaillance du groupe de cellules maîtresses vers le noeud maître, qui peut déterminer une réponse de réseau sur la base des informations de défaillance du groupe de cellules maîtresses. Le noeud maître peut transmettre la réponse de réseau à la cellule secondaire, qui peut relayer la réponse de réseau vers le dispositif sans fil.

Abstract: Aspects of the present disclosure provide mechanisms for delivering out-of-order PDCP PDUs to the PDCP sublayer. In a user equipment configured for dual connectivity between LTE and NR, upon delivering at least one out-of-order PDCP PDU from the RLC sublayer to the PDCP sublayer, a PDCP reordering timer may be initialized. To prevent discarding of LTE PDCP PDUs while the RLC sublayer is performing a retransmission procedure, prior to expiration of the PDCP reordering timer, the out-of-order LTE PDCP PDUs mapped to decoded LTE RLC PDUs may be delivered from the RLC sublayer to the PDCP sublayer without reordering thereof. When the PDCP reordering timer expires, any LTE PDCP PDUs mapped to missing LTE RLC PDUs may be discarded.
