数据重传方法及装置
摘要：
本发明公开了一种数据重传方法及装置。其中，所述数据重传方法包括：设置无线链路控制RLC层数据重传门限值；判断传输块TB的空闲空间小于所述数据重传门限值；使用新的TB重传所述RLC层的重传数据。本发明通过设置RLC层数据重传门限值，避免了重传数据的不适当拆分，有效控制了PDU的长度，节省了上下行数据传输带宽，减少了RLC重传数据处理的复杂度。
摘要（英）：

The invention discloses a data retransmission method and device. The data retransmission method comprises the following steps of: setting a data retransmission threshold value of a radio link control (RLC) layer; judging whether the free space of a transport block (TB) is smaller than the data retransmission threshold value; and retransmitting retransmission data of the RLC layer by using a new TB. By setting the data retransmission threshold value of the RLC layer, inappropriate de-clustering of the retransmission data is avoided, the length of a PDU (Protocol Data Unit) is controlled effectively, the uplink and downlink data transmission bandwidths are saved, and the processing complexity of RLC retransmission data is lowered.
