For example, the network device configures N uplink cells for the terminal; the network device configures corresponding M cells (M < = N) which can transmit PUCCH or are configured with PUCCH resources for a certain downlink cell of the terminal. And, the network device configures a priority or order for the M cells.
The network equipment indicates, through a first signaling, a carrier unit of the terminal for performing uplink carrier aggregation, or indicates a cell of the terminal, where the cell can perform uplink transmission, and the number of the cell is T (T < = N);
the terminal determines a cell corresponding to the T cell or the carrier unit indicated by the first signaling and a union of M cells, and uses a highest priority or a highest rank in the union of cells as an uplink cell for transmitting HARQ feedback of the downlink cell, that is, transmits HARQ feedback of a PDSCH of the downlink cell on a PUCCH of the uplink cell.
The uplink cell is a cell capable of performing at least uplink transmission; the downlink cell is a cell capable of performing at least downlink transmission.

step 501, the network equipment sends configuration information to the terminal;
wherein the configuration information comprises:
the network equipment configures a cell index for the terminal, and the cell index is associated with at least two cells configured with PUCCH resources or cells capable of transmitting HARQ feedback.
The configuration information may be predefined, or pre-configured or indicated to the terminal by the network device, and is not limited herein.
Step 502, the network device sends a first signaling to the terminal;
the first signaling is used for indicating a cell activated by a terminal, or a carrier unit for performing carrier aggregation, or a carrier unit or a cell capable of performing uplink transmission.
Step 503, the terminal determines a cell for transmitting the HARQ feedback;
specifically, the terminal determines the cell for transmitting the HARQ feedback according to at least one of the following information:
the cell index; determining at least two corresponding cells according to the association relationship between the cell indexes and the cells;
indicating a cell activated by a terminal, or a carrier unit for performing carrier aggregation, or a carrier unit or a cell capable of performing uplink transmission.
Here, determining, by the terminal according to the first signaling, a cell associated with the cell index for transmitting a PUCCH according to a predefined rule, where the PUCCH is used for the terminal to transmit HARQ feedback; i.e. the cell in which the HARQ feedback is transmitted.
Or selecting the cell with the highest sequencing or priority from the cells associated with the cell indexes for transmitting the PUCCH by the terminal according to the first signaling; the PUCCH is used for terminal transmission HARQ feedback, that is, a cell with highest ranking or priority is selected as a cell for transmitting HARQ feedback according to the first signaling.
Or the terminal receives other signaling sent by the network device, where the signaling is used to indicate an uplink cell associated with the cell index, and the uplink cell is used to transmit a PUCCH; the PUCCH is used for the terminal to transmit HARQ feedback, that is, the corresponding relationship between the cell index and the cell is modified through other signaling, so as to modify the cell transmitting HARQ feedback.
For example, the network device configures N uplink cells for the terminal; the network device configures an index of a certain downlink cell of the terminal, which can transmit the PUCCH or is configured with PUCCH resources, as I.
The network equipment indicates the cell activated by the terminal/the carrier units for carrying out uplink carrier aggregation to be T through the first signaling. The intersection of the T cell and the N cell is M cells.
Predefining a corresponding relation between the cell index I and the T cells, for example, the index I corresponds to the I-th cell in the T cells (the T cells are sorted according to a certain cell index); or the network equipment indicates or configures which cell in the T cells the index I corresponds to through signaling; or the terminal determines the uplink cell for transmitting the HARQ feedback of the downlink cell according to the priority of at least one cell in the T cells corresponding to the cell index I.
Or predefining a corresponding relationship between the cell index I and M cells, for example, the index I corresponds to an ith cell in the M cells (the M cells are sorted according to a certain cell index); or the network equipment indicates or configures which cell of the M cells the index I corresponds to through signaling; or the terminal determines the uplink cell for transmitting the HARQ feedback of the downlink cell according to the priority of at least one cell in the M cells corresponding to the cell index I.
And the terminal determines an uplink cell for transmitting the HARQ feedback of the downlink cell according to the corresponding relation, namely the terminal transmits the HARQ feedback of the downlink cell on the PUCCH of the uplink cell.
In still another embodiment, the communication method includes:
the network device may transmit the PUCCH or the cell configured with the PUCCH resource when the terminal is configured in different activated cells, or carrier units performing carrier aggregation, or cells or carrier units capable of performing uplink transmission.
The terminal determines a cell capable of transmitting PUCCH according to the situation of the activated cell, the carrier unit capable of carrying out carrier aggregation, or the cell or the carrier unit capable of carrying out uplink transmission, wherein the PUCCH is used for the terminal to transmit HARQ feedback.
For example, the network device configures N uplink cells for the terminal; the network device indicates that the number of carrier units or activated cells of uplink carrier aggregation of the terminal is T (T < = N) through a first signaling.
The network device may transmit HARQ feedback or a cell configured with PUCCH resources when a certain downlink cell of the terminal is configured in a different activated cell, or a carrier unit performing carrier aggregation, or a cell or a carrier unit capable of performing uplink transmission.
And the terminal determines the uplink cell for transmitting the HARQ feedback of the downlink cell according to the condition (such as whether PUCCH resources are configured, the priority of each cell and the like) of the T uplink cells corresponding to the carrier unit activated or subjected to carrier aggregation indicated by the current first signaling.
For example, for a certain downlink cell, a rule may be predefined to indicate how to select a cell for transmitting HARQ feedback; for example, the case of configuring the cell whose transmission HARQ feedback is configured is as follows:
if the cell 1 and the cell 2 are activated, selecting the cell for transmitting the HARQ feedback as the cell 1; if the cell 2 and the cell 3 are activated, selecting the cell for transmitting the HARQ feedback as the cell 2; if cell 1 and cell 3 are activated, the cell transmitting the HARQ feedback is selected as cell 1.
When the method is applied, the cell for transmitting the HARQ feedback is determined according to the actual situation based on the predefined rule.
