[0117] Application example 1
[0118] Such as image 3 As shown, the base station configures a terminal with two serving cells: a primary serving cell and a secondary serving cell, and the terminal is configured to use PUCCH format 3 to feed back HARQ-ACK response messages.
[0119] Assume that within a certain binding window, the terminal only receives a PDSCH from the autonomous serving cell without a PDCCH and a PDSCH corresponding to a PDCCH with a DAI value equal to 1, and assume that the TPC value on the PDCCH with a DAI value equal to 1 is "01" ".
[0120] It is assumed that the corresponding relationship between the value of ARI and the resource of PUCCH format 3 is shown in Table 1.
[0121] Table 1 The value of ARI and the resource correspondence table of PUCCH format 3

[0123]
[0124] When the terminal uses the above method 1-1 to feed back the HARQ-ACK response message, in the method 1-1, the TPC of the PDCCH with a DAI value equal to 1 will be reused as an ARI, ...

[0125] Application example 2
[0126] Such as Figure 4 As shown, the base station configures a terminal with a primary serving cell, and configures the terminal to use PUCCH format 3 to feed back HARQ-ACK response messages.
[0127] Assume that within a certain binding window, the terminal only receives a PDSCH from the autonomous serving cell without a PDCCH and a PDSCH corresponding to a PDCCH with a DAI value equal to 1, and assume that the TPC value on the PDCCH with a DAI value equal to 1 is "01" ".
[0128] It is assumed that the corresponding relationship between the value of ARI and the resource of PUCCH format 3 is shown in Table 1.
[0129] When the terminal uses the above method 1-1 to feed back the HARQ-ACK response message, in the method 1-1, the TPC of the PDCCH with a DAI value equal to 1 will be reused as an ARI, that is, the terminal is based on the received DAI value equal to 1. The TPC corresponding to the PDCCH and the PUCCH format 3 resource configured by the hi...
Example
[0132] Application example 3
[0133] The base station configures a terminal to use PUCCH format 3 to feed back the HARQ-ACK response message.
[0134] It is assumed that in a certain binding window, the terminal only receives a PDSCH without PDCCH and a PDCCH with a DAI value equal to 1 from the autonomous serving cell, and the corresponding relationship between the value of ARI and the resource of PUCCH format 3 is shown in Table 1.
[0135] When the terminal uses the above method 1-2 to feed back the HARQ-ACK response message, the terminal determines the PUCCH format 3 resource according to the default ARI value and the PUCCH format 3 resource configured by the higher layer. Assuming the default ARI value is "00", then According to Table 1, the terminal will use the PUCCH format 3 resource configured by the first higher layer to feed back the corresponding HARQ-ACK response message on PUCCH format 3.
[0136] Considering that the terminal may have DTX (Discontinuous Transmission) o...
