用于基于CBG的HARQ操作的重传机制
摘要：
在5G系统中，为了提供较高的数据速率，可以在单个时隙中发送针对一个传输块的大量码块(CB)。如果在5G中将支持大量码块，则针对一个传输块的一位混合自动重复请求肯定应答或否定应答(HARQ‑ACK)可能不是所希望的。本文描述的是用于利用基于码块(CB)或CB的组(被称为码块组(CBG))的HARQ‑ACK来更高效地重传和接收未成功解码的数据的机制。
摘要（英）：

In 5G systems, to provide higher data rates, a large number of code blocks (CBs) for one transport block may be transmitted in a single slot. Given that a large number of code blocks would be supported in 5G, one-bit hybrid automatic repeat request acknowledgements or non-acknowledgements (HARQ-ACKs) for one transport block may not be desirable. Described herein are mechanisms for utilizing HARQ-ACKs based upon code blocks (CBs) or groups of CBs, referred to as code block groups (CBGs), to more efficiently retransmit and receive unsuccessfully decoded data.
