Abstract

本申请提供一种无线链路控制层的数据接收处理的方法和设备，该方法包括：接收目标RLC PDU；若目标RLC PDU的数据域仅包括一个完整的RLC SDU的一个切割段，根据目标RLC PDU中包括的序列号SN的值对应的重装定时器的当前运行状态对目标RLC PDU进行处理，或丢弃RLC PDU，目标RLC PDU为多个RLC PDU中的一个，多个RLC PDU中包括的SN的值相同，多个RLC PDU能够被重装成完整的RLC SDU，当前运行状态为下列运行状态中的一种：未被启动状态、计时状态和超时状态。本申请提供的方法，适用于不支持SDU级联和按序递交的无线通信系统，并能简化通信系统的实现。
