Title (EN) RADIO LINK CONTROL UNACKNOWLEDGED MODE RECEIVE TECHNIQUES
(FR) TECHNIQUES DE RÉCEPTION EN MODE SANS ACCUSÉ DE RÉCEPTION DE COMMANDE DE LIAISON RADIO
Abstract:
(EN) A wireless device may receive a radio link control (RLC) protocol data unit (PDU) from a lower layer (e.g., from a media access control (MAC) layer) when processing communications (e.g., packets) received from another wireless device. The receiving wireless device may identify that the PDU is an RLC service data unit (SDU) segment based at least in part on an indication corresponding to a sequence number associated with the RLC SDU segment. The receiving wireless device may then determine that the RLC SDU segment is received out of order based on previously received PDUs or previously received RLC SDU segments, and initiate a reassembly timer based on the out of order determination for the RLC SDUs. If the remaining RLC SDU segments (e.g., that complete the RLC SDU) are received before reassembly timer expires, the wireless device may reassemble the RLC SDU to be passed to a higher layer.
(FR) L'invention concerne un dispositif sans fil pouvant recevoir une unité de données de protocole (PDU) de commande de liaison radio (RLC) à partir d'une couche inférieure (par exemple, à partir d'une couche de commande d'accès au support (MAC)) lors du traitement de communications (par exemple, des paquets) reçues d'un autre dispositif sans fil. Le dispositif sans fil de réception peut identifier que la PDU est un segment d'unité de données de service (SDU) RLC sur la base, au moins en partie, d'une indication correspondant à un numéro de séquence associé au segment de SDU RLC. Le dispositif sans fil de réception peut ensuite déterminer que le segment de SDU RLC est reçu hors service sur la base de PDU reçues précédemment ou de segments de SDU RLC reçus précédemment, et initier un temporisateur de réassemblage sur la base de la détermination hors service des SDU RLC. Si les segments de SDU RLC restants (par exemple, qui complètent la SDU RLC) sont reçus avant l'expiration du temporisateur de réassemblage, le dispositif sans fil peut réassembler la SDU RLC devant être transmise à une couche supérieure.
