PDSCH HARQ

PDSCH-ServingCellConfig ::
nrofHARQ-ProcessesForPDSCH
The number of HARQ processes to be used on the PDSCH of a serving cell.
Value n2 corresponds to 2 HARQ processes,
value n4 corresponds to 4 HARQ processes, and so on.
If the field is absent, the UE uses 8 HARQ processes (see TS 38.214 [19], clause 5.1).

PDSCH-Config ::
pdsch-AggregationFactor
Number of repetitions for data (see TS 38.214 [19], clause 5.1.2.1). When the field is absent the UE applies the value 1.

38.212
7.3.1.1.1 Format 0_0
7.3.1.1.2 Format 0_1
7.3.1.2.1 Format 1_0
7.3.1.2.2 Format 1_1
- HARQ process number – 4 bits

PDSCH同一个HARQ ID
新传RV=0，gNB侧的L2给L1下发一份数据，L1对该数据进行译码，存入HARQ循环buff，从buff中取出RV=0的数据，进行发送；
如果新传的PDSCH数据，UE侧反馈NACK，则gNB侧L2将会进行重传，将需要发送数据再次发送给L1(指示RV版本为2)
gNB侧的L1收到重传数据后(重传和新传数据一样)，对该数据进行译码，存入HARQ循环buff，从buff中取出RV=2的数据进行发送；

备注：
1. 新传和重传，L2发给L1的数据内容相同；
2. 新传和重传，L1的HARQ循环buff中的内容可能一样 (调度参数保持不变)，也可能不一样(调度参数有变化)
3. 新传的RV0是从新传的HARQ循环buff中取出；
4. 重传的RV2是从重传的HARQ循环buff中取出；
5. 重传和新传的TBS必须保持一致，MCS和RB可以变化；

【沿着高速路感受中国活力】As of the end of 2020, China's total mileage of highways reached 160,000 kilometers. Highways in China, which have been built from scratch and developed rapidly over the past three decades, have become a great window on the development, changes, and achievements of China. 从无到有、连线成网。30多年来，中国#高速公路#飞速发展，截至2020年底总里程达16万公里。沿着高速公路看发展、看变化、看成就，无疑是观察中国的一个绝佳窗口。
