Title (EN) RADIO LINK CONTROL REASSEMBLING TECHNIQUES IN WIRELESS SYSTEMS
(FR) TECHNIQUES DE RÉASSEMBLAGE DE COMMANDE DE RADIOLIAISON DANS DES SYSTÈMES SANS FIL
Abstract:
(EN) Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a transmitting device may identify a Radio Link Control (RLC) service data unit (SDU) to be transmitted to a receiving device. In some cases, the transmitting device may not have access to sufficient resources to transmit the entire RLC SDU. As such, the transmitting device may segment the RLC SDU into RLC SDU segments, and the transmitting device may transmit the RLC SDU segments to the receiving device. If an RLC layer at the receiving device receives one or more RLC SDU segments out of sequence, the RLC layer may initiate a reassembly (or reordering) timer. The RLC layer may reassemble the successfully received RLC SDU segments to be passed to upper layers. Once the timer expires, the RLC layer may declare that the missing RLC SDU segments are lost.
(FR) L'invention concerne des procédés, des systèmes, et des dispositifs de communication sans fil. Dans certains systèmes de communication sans fil, un dispositif de transmission peut identifier une unité de données de service (SDU) de commande de radioliaison (RLC) devant être transmise à un dispositif de réception. Dans certains cas, le dispositif de transmission peut ne pas avoir accès à des ressources suffisantes pour transmettre la totalité de la SDU RLC. Le dispositif de transmission peut alors segmenter la SDU RLC en segments de SDU RLC, et le dispositif de transmission peut transmettre les segments de SDU RLC au dispositif de réception. Si, au dispositif de réception, une couche RLC reçoit un ou plusieurs segments de SDU RLC externes à une séquence, la couche RLC peut initier un temporisateur de réassemblage (ou de réordonnancement). La couche RLC peut réassembler les segments de SDU RLC reçus avec succès, devant être transmis à des couches supérieures. Lorsque le temporisateur expire, la couche RLC peut déclarer que les segments de SDU RLC manquants sont perdus.
