As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0083] The following technologies are supported in the related technology: one DCI (multi-cell scheduling DCI, referred to as mc-DCI, such as DCI format 3-0, DCI format 3-1) schedules the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) or physical downlink shared channel (Physical downlink shared channel, PDSCH) of multiple cells.

[0084] And supports the following frameworks:

[0085] A plurality of cells may be divided into a plurality of cell sets. For example, a cell set (cell1 / 2 / 3 / 4 / 5 / 6 / 7 / 8) may be divided into two cell sets (cell1 / 2 / 3 / 4) and a cell set (cell5 / 6 / 7 / 8).

[0086] A cell set can be divided into multiple cell combinations (cell combinations), for example, a cell set (cell1 / 2 / 3 / 4) can include a cell combination (cell1 / 2 / 3, cell1 / 2 / 4, cell1 / 3);

[0087] One DCI can schedule and / or indicate one cell combination at a time. There are two specific scheduling and / or indication methods:

[0088] Method 1: cell indicator based

[0089] The Radio Resource Control (RRC) message configures a cell combination table for each cell set. Each cell combination table has a corresponding index. The mc-DCI carries a field to indicate an index. For example, if '01' corresponds to cell1 / 3, then the mc-DCI indicates '01', indicating that cell1 / 3 is indicated. The mc-DCI only carries the frequency domain resource allocation (FDRA) field of cell1 / 3.

[0090] Method 2: FDRA based

[0091] In the above example, mc-DCI carries the FDRA field of cell1 / 2 / 3 / 4. If the FDRA field indicates an invalid value, it means that this cell is not scheduled.

[0092] Each cell set has a reference cell, and the number of blind detections and the DCI size of the mc-DCI of the cell set are calculated on the reference cell;

[0093] Each reference cell or cell set or each cell has a corresponding DCI number limit and / or scheduling number limit.

[0094] For example, in a monitoring occasion, there are at most N1 mc-DCIs for the reference cell or cell set (at least some cells in the cell set can be scheduled).

[0095] For example, in one monitoring occasion, there are at most N2 sc-DCIs (single-cell scheduling DCIs) for one cell in the cell set (the cell can be scheduled).

[0096] When counting the downlink assignment index (DAI), if a certain cell combination is scheduled, the DAI is counted for the cell with the smallest cell identification (ID) in the cell combination (for example, DAI+1), or the DAI count is performed based on the cell with the smallest cell ID in the cell combination to generate a hybrid automatic repeat request acknowledgement (HARQ-ACK) bit. Here, the DAI count can be regarded as associating the DAI count with the cell with the smallest cell ID in the cell combination.

[0097] When generating the HARQ-ACK bit number, the cell set dimension is traversed, and each cell in the cell set is traversed, so that the HARQ-ACK bit corresponding to each cell is connected in series to generate the HARQ-ACK bit. The HARQ-ACK bit information corresponding to a cell combination is placed in the bit position corresponding to the cell with the smallest cell ID in the cell combination. For cells that have not been scheduled, a corresponding negative acknowledgement (NACK) is generated.

[0098] Among them, mc-DCI can carry dormancy indication information, can carry an explicit dormancy indication field, or use the modulation and coding scheme (MCS) corresponding to a certain cell, the hybrid automatic repeat request (HARQ) process and other fields to indicate the dormancy indication information.

[0099] In the prior art, if an mc-DCI schedules data of O cells (O>=2), the feedback information corresponding to the mc-DCI is placed in the second subcodebook, and the position of its HARQ-ACK feedback information corresponds to the cell with the smallest ID among the O cells. And this type of mc-DCI will be counted in the DCI number limit of the scheduled cell or the corresponding reference cell.

[0100] However, an mc-DCI can not only indicate and / or schedule multiple cells, but also indicate dormancy indication information. Although the mc-DCI indicates and / or schedules certain cells, the resource allocation information (such as FDRA) of these cells is invalid, so there is no actual data. Therefore, how to determine which cell this type of mc-DCI belongs to, how to perform blind detection, which DCI number limit corresponds to, the terminal's ability to process this type of mc-DCI, and how to generate the corresponding feedback information are issues that need to be solved.

[0101] In combination with the accompanying drawings, the method, apparatus, terminal and network side equipment for sending and receiving downlink control information DCI provided in the embodiments of the present application are described in detail through some embodiments and their application scenarios.
