Abstract
Disclosed are a data feedback, sending and receiving method and device, a receiving device and a sending device. The data feedback method includes generating a hybrid automatic repeat request acknowledgement (HARQ-ACK) for transmitted data; and feeding back the HARQ-ACK to a sending end.
Claims18
A data feedback method, comprising:
- generating a hybrid automatic repeat request acknowledgement (HARQ-ACK) for transmitted data;
- and
- feeding back the HARQ-ACK to a sending end;
- wherein generating the HARQ-ACK for the transmitted data comprises at least one of:
- generating a first HARQ-ACK of a transport block (TB) level for each TB in the transmitted data, wherein each TB corresponds to one HARQ-ACK bit;
- or
- generating a second HARQ-ACK of a code block group (CBG) level for each incorrectly decoded TB in the transmitted data, wherein each CBG corresponds to one HARQ-ACK bit;
- and
- wherein generating the second HARQ-ACK of the CBG level for each incorrectly decoded TB in the transmitted data comprises:
- according to an order of TB in the transmitted data, sequentially generating the second HARQ-ACK for each TB of the negative acknowledgement (NACK).
7 more elements
A data sending method, comprising:
- sending transmitted data to a receiving end;
- and
- receiving a fed back hybrid automatic repeat request acknowledgement (HARQ-ACK) which is formed by the receiving end for the transmitted data according to an agreed rule;
- wherein the receiving end generates the HARQ-ACK for the transmitted data in at least one of the following manners:
- generating a first HARQ-ACK of a transport block (TB) level for each TB in the transmitted data respectively, wherein each TB corresponds to one HARQ-ACK bit;
- or
- generating a second HARQ-ACK of a code block group (CBG) level for each incorrectly decoded TB in the transmitted data, wherein each CBG corresponds to one HARQ-ACK bit and
- wherein generating the second HARQ-ACK of the CBG level for each incorrectly decoded TB in the transmitted data comprises:
- according to an order of TB in the transmitted data, sequentially generating the second HARQ-ACK for each TB of the negative acknowledgement (NACK).
6 more elements
A data feedback device, comprising:
- a processor;
- and
- a memory connected to the processor for storing instructions executable by the processor,
- wherein execution of the instructions by the processor causes the processor to perform a data feedback method,
- wherein the data feedback method comprises:
- generating a hybrid automatic repeat request acknowledgement (HARQ-ACK) for transmitted data;
- and
- feeding back the HARQ-ACK to a sending end;
- wherein generating the HARQ-ACK for the transmitted data comprises at least one of:
- generating a first HARQ-ACK of a transport block (TB) level for each TB in the transmitted data, wherein each TB corresponds to one HARQ-ACK bit;
- or
- generating a second HARQ-ACK of a code block group (CBG) level for each incorrectly decoded TB in the transmitted data, wherein each CBG corresponds to one HARQ-ACK bit and
- wherein generating the second HARQ-ACK of the CBG level for each incorrectly decoded TB in the transmitted data comprises:
- according to an order of TB in the transmitted data, sequentially generating the second HARQ-ACK for each TB of the negative acknowledgement (NACK).
