It is to be understood that, in the embodiment of the present invention, the value of the priority level indication field is not particularly limited.

Step 1202: and transmitting the HARQ-ACK according to the priority of the HARQ-ACK.

If necessary, the content of step 1202 is the same as that of step 302, and will not be described here.

The following description is made for the manner of determining the priority of the HARQ-ACK carried on different PUCCH resources in fig. 5 to 12, respectively, and it is understood that, besides the following exemplary manner, other similar manners of determining the priority of the HARQ-ACK may be conceivable by those skilled in the art, and will not be described herein again.

The first method is as follows:

the terminal determines whether HARQ-ACK carried by a PUCCH Resource (indicated by a PUCCH Resource Indication (PRI)) indicated in DCI has a high priority according to configuration of a Time Domain Resource Assignment (TDRA) in the DCI, specifically, the following manner is used:

(1) the network configures the priority of the Index value (Index) in the time domain resource allocation field in the DCI, for example: and one part of index values in the time domain resource allocation domain are high priority, and the other part of index values in the time domain resource allocation domain are low priority.

Illustratively, the first 8 index values in Table 1 have a higher priority than the last 8 index values, e.g., "0000" has a higher priority than "1111".

If the terminal detects the first DCI and the second DCI, the index value in the time domain resource allocation domain in the first DCI is "0001", the index value in the time domain resource allocation domain in the second DCI is "1111", the priority of the index value "0001" is higher than the priority of the index value "1111", and the priority of the HARQ-ACK carried by the PUCCH resource indicated by the first DCI is higher than the priority of the HARQ-ACK carried by the PUCCH resource indicated by the second DCI. (2) The network configures the priority of mapping Type (mapping Type) in the time domain resource allocation field in DCI, for example: the mapping type "X2" in table 1 is high priority and the mapping type "Z2" is low priority.

If the terminal detects the third DCI and the fourth DCI, the mapping type in the time domain resource allocation domain in the third DCI is "X2", the mapping type in the time domain resource allocation domain in the fourth DCI is "Z2", the priority of the mapping type "X2" is higher than the priority of the mapping type "Z2", and the priority of the HARQ-ACK carried by the PUCCH resource indicated by the third DCI is higher than the priority of the HARQ-ACK carried by the PUCCH resource indicated by the fourth DCI. (3) The network configures the priority of the granularity of the k0 value in the time domain resource allocation field in DCI.

Illustratively, the granularity of all k0 values is divided into two parts, with the first granularity having a higher priority than the second granularity, e.g., the first granularity being a symbol granularity or a sub-slot granularity, and the second granularity being a slot granularity.

If the terminal detects the fifth DCI and the sixth DCI, the granularity of the k0 value in the time domain resource allocation domain in the fifth DCI is a first granularity, the granularity of the k0 value in the time domain resource allocation domain in the second DCI is a second granularity, the priority of the first granularity is higher than that of the second granularity, and the priority of the HARQ-ACK carried by the PUCCH resource indicated by the fifth DCI is higher than that of the HARQ-ACK carried by the PUCCH resource indicated by the sixth DCI.

The second method comprises the following steps:

the terminal determines whether the HARQ-ACK carried by the PUCCH Resource (indicated by the PRI) indicated in the DCI has a high priority according to the priority of a Time Domain Resource Allocation (TDRA) in the DCI.

Illustratively, the network configures a high priority time domain resource allocation domain, such as: TDRA mode1, if the PDSCH indicated by one DCI is configured with TDRA mode1, the priority of HARQ-ACK carried by PUCCH resource indicated by the DCI is higher than the priority of HARQ-ACK carried by PUCCH resource indicated by other DCI.

See table 2 for an example of TDRA mode 1.

Table 2:

Index	PDCCH to PDSCH spacing (symbol granularity)	Length
			0000	X1	X2
0001	Y1	Y2
			…	…	…
1111	Z1	Z2

The third method comprises the following steps:

and the terminal determines the priority of HARQ-ACK carried by the PUCCH Resource indicated by the DCI according to the configured priority of the Nominal Resource block group size P (Nominal RBG size P) of the PDSCH indicated by the DCI.

Illustratively, configuration 2 has the highest priority.

If the configuration of the Nominal RBG size P of the PDSCH indicated by the DCI is 2, the HARQ-ACK carried by the PUCCH resource indicated by the DCI has the highest priority.

Illustratively, configuration 2 has a higher priority than configuration 1.

If the configuration of the Nominal RBG size P of the PDSCH indicated by the eighth DCI is configuration 2, and if the configuration of the Nominal RBG size P of the ninth DCI is configuration 1, the priority of the HARQ-ACK carried by the PUCCH resource indicated by the eighth DCI is higher than the priority of the HARQ-ACK carried by the PUCCH resource indicated by the ninth DCI.

The method is as follows:

and the terminal determines the priority of the HARQ-ACK carried by the PUCCH resource indicated by the DCI according to the priority indication domain of the DCI.

A priority indication field is added in the DCI, and the priority indication field indicates whether HARQ-ACK carried by the PUCCH resource (indicated by PRI) indicated by the DCI has high priority or not.

For example: a 1 bit (bit) priority indication field is added in the DCI, if the field value of the priority indication field is '1', the HARQ-ACK carried by the PUCCH resource (indicated by PRI) indicated by the DCI has high priority; if the domain value of the priority indication field is "0", the HARQ-ACK carried by the PUCCH resource (indicated by the PRI) indicated by the DCI does not have a high priority, for example: has the same priority as the other HARQ-ACKs.

The embodiment of the invention also provides a terminal, and as the principle of solving the problem of the terminal is similar to the hybrid automatic repeat request response transmission method in the embodiment of the invention, the implementation of the terminal can refer to the implementation of the method, and the repeated parts are not repeated.
