Abstract
(EN)
Disclosed are a data retransmission decoding method, apparatus and system, and a communication device. The method comprises: obtaining retransmitted data to be decoded, the retransmitted data to be decoded comprising a code block to be decoded (S102); according to the stored check state information of a code block decoded the last time, determining whether the code block to be decoded comprises a target code block required to be decoded again (S104); if the code block to be decoded comprises the target code block required to be decoded again, merging and decoding the currently stored first code block and the target code block on the basis of a predetermined parameter (S106), wherein the first code block is a code block corresponding to the target code block.

L'invention concerne un procédé, un appareil et un système de décodage de retransmission de données, ainsi qu'un dispositif de communication. Le procédé consiste à : obtenir des données retransmises devant être décodées, les données retransmises devant être décodées contenant un bloc de code devant être décodé (S102) ; en fonction des informations sur un état de vérification stockées d'un bloc de code décodé en dernier lieu, déterminer si le bloc de code devant être décodé contient un bloc de code cible requis pour un nouveau décodage (S104) ; le cas échéant, fusionner et décoder le premier bloc de code actuellement stocké et le bloc de code cible sur la base d'un paramètre prédéterminé (S106), le premier bloc de code étant un bloc de code correspondant au bloc de code cible.

本申请实施例公开了一种数据的重传解码方法、装置、系统及通信设备,所述方法包括:获取重传待解码数据,重传待解码数据中包括待解码的码块(S102),根据存储的上次解码的码块校验状态信息,判断待解码的码块中是否包含需要再次解码的目标码块(S104),如果待解码的码块中包含需要再次解码的目标码块,则基于预定解码参数,将当前存储的第一码块与目标码块进行合并解码(S106),其中,第一码块为与目标码块对应的码块。
