[0044] To facilitate understanding of the solutions provided in the embodiments of this application, the current downlink control information (DCI) format is described below:

[0045] The scheduling DCI format in NR includes DCI formats 0_0 / 0_1 / 0_2 / 1_0 / 1_1 / 1_2. For example, DCI format 1_0 contains the following information: DCI format identifier, frequency domain resource assignment, time domain resource assignment, VRB-to-PRB mapping, modulation and coding scheme, new data indicator, redundancy version, hybrid automatic repeat request process number, downlink assignment index, transmission power control command for scheduled PUCCH, PUCCH resource indicator, and PDSCH-to-HARQ feedback timing indicator.

[0046] For example, DCI format 1_1 contains the following information: carrier indicator, DCI format identifier, bandwidth part indicator, frequency domain resource allocation, time domain resource allocation, VRB-to-PRB mapping, physical resource block bundling size indicator, rate matching indicator, ZP CSI-RS trigger, transport block 1, transport block 2, number of HARQ processes, downlink allocation index, TPC command for scheduling PUCCH, PUCCH resource indicator, timing indicator from PDSCH to HARQ feedback, antenna ports, transmission configuration indication, SRS request, code block group transmission information, code block group flushing outinformation, and demodulation reference signal sequence initialization. Transport block 1 includes the modulation and coding scheme, new data indicator, and redundancy version. Transport block 2 also includes modulation and coding schemes, new data indications, and redundant versions.

[0047] Information regarding other DCI formats can be found in existing standards and will not be repeated here. The DCI format in this embodiment may also be other than DCI format 0_0 / 0_1 / 0_2 / 1_0 / 1_1 / 1_2. This embodiment does not limit the DCI format.

[0048] To support a single DCI format that can schedule one or multiple cells flexibly, this application provides a cell scheduling method, apparatus, chip, and module device. The cell scheduling method, apparatus, chip, and module device provided in the embodiments of this application are further described in detail below.

[0049] Figure 2 This is a flowchart illustrating a cell scheduling method provided in an embodiment of this application. Figure 2 As shown, the cell scheduling method includes the following steps 201 and 202. Figure 2 The method shown can be implemented by terminal devices and network devices. Alternatively, Figure 2 The method shown can be executed by a chip in a terminal device or a chip in a network device. Figure 2 The method will be explained using terminal devices and network devices as examples.

[0050] 201. The network device sends the first DCI to the terminal device. Accordingly, the terminal device can receive the first DCI.

[0051] In this embodiment of the application, the first DCI includes a first field, which indicates the first DCI scheduling target cell group or the first cell, and the target cell group includes multiple cells.

[0052] For example, suppose the first DCI schedules cell group 1, cell group 2, or cell 1. When the value of the first field is 00, it indicates scheduling cell group 1; when the value of the first field is 01, it indicates scheduling cell group 2; and when the value of the first field is 11, it indicates scheduling cell 1.

[0053] It should be noted that network devices can schedule one or more cells via the first DCI self-carrier, or they can schedule one or more cells via the first DCI cross-carrier.

[0054] For example, assuming the first cell is cell 1, the network device sends a first DCI to the terminal device in cell 1. This first field indicates that the first DCI schedules cell 1. In other words, the network device can schedule cell 1 via the first DCI using a self-carrier.

[0055] For example, suppose the target cell group includes cell 1 and cell 2. The network device sends a first DCI to the terminal device in cell 1. The first field of this first DCI indicates that the target cell group can be scheduled using the first DCI. In other words, the network device can schedule cell 1 and cell 2 using the first DCI via carrier scheduling.

[0056] For example, suppose the first cell is cell 2. The network device sends a first DCI to the terminal device in cell 1. The first field of this first DCI indicates that cell 2 can be scheduled. In other words, the network device can schedule cell 2 across carriers through the first DCI.

[0057] For example, assuming the target cell group is cells 2 and 3, the network device sends a first DCI to the terminal device in cell 1. The first field of this first DCI indicates that the target cell group can be scheduled. In other words, the network device can schedule cells 2 and 3 across carriers through the first DCI.

[0058] 202. The terminal device determines the length of the field in the first DCI based on the first field.

[0059] In this embodiment, the terminal device determines the length of a field in the first DCI based on the scheduling method indicated by the first field, thereby reading the scheduling information in the first DCI. As explained above, the scheduling method indicated by the first field can be either instructing the DCI to schedule multiple cells or instructing the DCI to schedule one cell. The length of the field in the first DCI may differ depending on the scheduling method indicated by the first field. Therefore, the terminal device can determine the length of the field in the first DCI based on the scheduling method indicated by the first field.

[0060] It can be seen that, based on Figure 2 The described method allows for scheduling of multiple cells or a single cell using the same DCI format. A first field in the DCI enables the terminal device to distinguish the scheduling status of the received DCI. Therefore, based on... Figure 2 The described method allows for flexible cell scheduling using a DCI format.

[0061] In one possible implementation, when the first field indicates that the first DCI is scheduling a target cell group, the first DCI has a common field used for joint scheduling of the target cell group. That is, in this embodiment, the field used for joint scheduling of the target cell group can be called a common field. In this embodiment, the field used for joint scheduling of the target cell group may not be called a common field, or may be called by other names, which are not limited here.

[0062] The first DCI may include one or more common fields. All fields in the first DCI may be common fields, or some fields in the first DCI may be common fields. For example, the first DCI may include the following fields: frequency domain resource allocation field, modulation and coding scheme field, new data indication field, etc. Assuming the frequency domain resource allocation field is used for joint scheduling of target cell groups, then the frequency domain resource allocation field is a common field.

[0063] For example, such as Figure 3 As shown in Table 1, assuming the frequency domain resource allocation field is a common field, when the value of the frequency domain resource allocation field is 00, it indicates that the frequency domain resource allocation of cell 1 is resource 1, and the frequency domain resource allocation of cell 2 is resource 2; when the value of the frequency domain resource allocation field is 01, it indicates that the frequency domain resource allocation of cell 1 is resource 3, and the frequency domain resource allocation of cell 2 is resource 4; when the value of the frequency domain resource allocation field is 10, it indicates that the frequency domain resource allocation of cell 1 is resource 5, and the frequency domain resource allocation of cell 2 is resource 6; when the value of the frequency domain resource allocation field is 11, it indicates that the frequency domain resource allocation of cell 1 is resource 7, and the frequency domain resource allocation of cell 2 is resource 8.

[0064] Table 1

[0065] 00 Resource 1 Resource 2 01 Resource 3 Resource 4 10 Resource 5 Resource 6 11 Resource 7 Resource 8

[0066] The target cell group is jointly scheduled using a common field, meaning that the scheduling information of multiple cells can be indicated by a single common field, thereby reducing the DCI payload size.

[0067] Figure 4 This is a flowchart illustrating a cell scheduling method provided in an embodiment of this application. Figure 4 As shown, the cell scheduling method includes the following steps 401 to 403. Figure 4 The method shown can be implemented by terminal devices and network devices. Alternatively, Figure 4 The method shown can be executed by a chip in a terminal device or a chip in a network device. Figure 4 The method will be illustrated using terminal devices and network devices as the implementing entities. Step 403 is a specific implementation of step 202 described above.

[0068] 401. The network device sends a first signaling message to the terminal device. Accordingly, the terminal device receives the first signaling message.

[0069] In this embodiment, the first signaling is used to configure one or more cell groups that the DCI allows scheduling. The first signaling includes configuration information for common fields in the DCI corresponding to the cell group. This configuration information is used to configure candidate values ​​for the common fields and field information for each cell in the cell group corresponding to the candidate values. The one or more cell groups include a target cell group. It should be noted that the network device can configure the common fields using the first signaling, and correspondingly, the terminal device can determine the length of the common fields based on the configuration information of the common fields.

[0070] For example, as shown in Table 2 below, it is assumed that when DCI schedules cell group 1, the frequency domain resource allocation field is a common field; when DCI schedules cell group 2, the frequency domain resource allocation field is also a common field. The first signaling configuration allows DCI within the first cell to schedule cell group 1 and cell group 2. Cell group 1 includes cell 1 and cell 2; cell group 2 includes cell 1 and cell 3. This first signaling includes configuration information for the common field corresponding to cell group 1, i.e., configuration information 1 for the frequency domain resource allocation field; and configuration information for the common field corresponding to cell group 2, i.e., configuration information 2 for the frequency domain resource allocation field. Table 2 uses the example where the common field in DCI is the same when scheduling cell group 1 as when scheduling cell group 2. However, the common field in DCI when scheduling cell group 1 and the common field in DCI when scheduling cell group 2 can also be different, and this application embodiment does not limit this. For example, the common field in DCI when scheduling cell group 1 can be the frequency domain resource allocation field, and the common field in DCI when scheduling cell group 2 can be the modulation and coding scheme field.

[0071] Table 2

[0072] Community Group 1 (Community 1 + Community 2) Configuration information for the frequency domain resource allocation field 1 Community Group 2 (Community 1 + Community 3) Configuration information for the frequency domain resource allocation field 2

[0073] Configuration information 1 can be as shown in Table 1 above. Configuration information 1 includes candidate values ​​for the frequency domain resource allocation field and the frequency domain resource allocation information for cell 1 and cell 2 corresponding to each candidate value.

[0074] Configuration information 2 is shown in Table 3 below. Configuration information 2 includes candidate values ​​for the frequency domain resource allocation field and the corresponding frequency domain resource allocation information for cell 1 and cell 3. Specifically, when the value of the frequency domain resource allocation field is 00, it indicates that the frequency domain resource allocation for cell 1 is resource 8, and the frequency domain resource allocation for cell 3 is resource 7; when the value of the frequency domain resource allocation field is 01, it indicates that the frequency domain resource allocation for cell 1 is resource 6, and the frequency domain resource allocation for cell 3 is resource 5; when the value of the frequency domain resource allocation field is 10, it indicates that the frequency domain resource allocation for cell 1 is resource 4, and the frequency domain resource allocation for cell 3 is resource 3; when the value of the frequency domain resource allocation field is 11, it indicates that the frequency domain resource allocation for cell 1 is resource 2, and the frequency domain resource allocation for cell 3 is resource 1.

[0077] 402. The network device sends the first DCI to the terminal device. Accordingly, the terminal device can receive the first DCI.

[0078] The specific implementation of step 402 can be referred to the specific implementation of step 201 above, and will not be repeated here.

[0079] 403. If the first field indicates the target cell group for the first DCI scheduling, the terminal device determines the length of the common field in the first DCI based on the configuration information of the common field corresponding to the target cell group.

[0080] In this embodiment, when the first field indicates a target cell group for the first DCI scheduling, the first DCI has a common field. The terminal device can determine the length of the candidate value in the configuration information of the common field as the length of the common field in the first DCI.

[0081] For example, assuming the target cell group is cell group 1, the frequency domain resource allocation field in the first DCI is a common field, and the configuration information of the frequency domain resource allocation field is shown in Table 1 above. Therefore, the length of the frequency domain resource allocation field is 2 bits.

[0082] In one possible implementation, the method further includes: the network device sending a second signaling message to the terminal device, the second signaling message indicating the number of bits corresponding to each cell in a non-public field in one or more cell groups, the non-public field being used for independent scheduling of cells in the cell group. Accordingly, the terminal device receives the second signaling message sent by the network device; if the first field indicates a first DCI scheduling target cell group, the terminal device determines the length of the non-public field in the first DCI based on the second signaling message. It should be noted that the non-public field can be represented as a separate field. The non-public field in the embodiments of this application can also be called other names, which are not limited here.

[0083] In this embodiment, the non-common fields in the DCI corresponding to different cell groups may be the same or different, and this application does not limit this. For example, the non-common fields in the DCI corresponding to cell group 1 may be a frequency domain resource allocation field and a modulation and coding scheme field. The non-common fields in the DCI corresponding to cell group 2 may be a frequency domain resource allocation field and a new data indication field. Again, the non-common fields in the DCI corresponding to cell group 1 may be a frequency domain resource allocation field and a modulation and coding scheme field. The non-common fields in the DCI corresponding to cell group 2 may be a frequency domain resource allocation field and a modulation and coding scheme field.

[0084] It should be noted that non-public fields can independently schedule cells within a cell group. For example, a cell group includes cell 1 and cell 2. Assume the modulation and coding scheme field in the first DCI is a non-public field. A portion of the bits in this modulation and coding scheme field indicates the modulation and coding scheme of cell 1, and another portion indicates the modulation and coding scheme of cell 2. For example, assuming the modulation and coding scheme field includes two bits, the first bit can be used to indicate the modulation and coding scheme of cell 1, and the second bit can be used to indicate the modulation and coding scheme of cell 2.

[0085] The number of bits occupied by the same cell in the same non-public field in different cell groups can be the same or different.

[0086] Let's take the example of the same cell in different cell groups occupying the same number of bits in the same non-common field. Assume the first signaling configuration (DCI) allows scheduling of cell group 1 and cell group 2. Cell group 1 includes cell 1 and cell 2; cell group 2 includes cell 1 and cell 3. The second signaling can indicate the number of bits corresponding to cell 1, cell 2, and cell 3 in the non-common field. For example, assume the DCI includes the following fields: frequency domain resource allocation, modulation and coding scheme, and new data indication. The DCI may also include other fields; for ease of description, we will now assume the DCI includes three fields. Assuming the frequency domain resource allocation field, modulation and coding scheme field, and new data indication field are non-common fields, the number of bits corresponding to cell 1 in cell group 1 in the frequency domain resource allocation field is the same as the number of bits corresponding to cell 1 in cell group 2 in the frequency domain resource allocation field, the number of bits corresponding to cell 1 in cell group 1 in the modulation and coding scheme field is the same as the number of bits corresponding to cell 1 in cell group 2 in the modulation and coding scheme field, and the number of bits corresponding to cell 1 in cell group 1 in the new data indication field is the same as the number of bits corresponding to cell 1 in cell group 2 in the new data indication field.

[0087] For cell group 1, the second signaling indicates the number of bits corresponding to cell 1 in the frequency domain resource allocation field, which is 1 bit; the number of bits corresponding to cell 1 in the modulation and coding scheme field, which is 1 bit; and the number of bits corresponding to cell 1 in the new data indication field, which is 1 bit. For cell 2 in cell group 1, the number of bits corresponding to cell 2 in the frequency domain resource allocation field is 2 bits; the number of bits corresponding to cell 2 in the modulation and coding scheme field, which is 2 bits; and the number of bits corresponding to cell 2 in the new data indication field, which is 2 bits.

[0088] For cell group 2, the second signaling also indicates the number of bits corresponding to cell 1 in the frequency domain resource allocation field, which is also 1 bit; the number of bits corresponding to cell 1 in the modulation and coding scheme field, which is also 1 bit; and the number of bits corresponding to cell 1 in the new data indication field, which is also 1 bit. For cell 3 in cell group 2, the number of bits corresponding to cell 3 in the frequency domain resource allocation field is 3 bits; the number of bits corresponding to cell 3 in the modulation and coding scheme field is 3 bits; and the number of bits corresponding to cell 3 in the new data indication field is 3 bits.

[0089] Take, for example, the number of bits occupied by the same cell in the same non-common field differs across different cell groups. Assume the frequency domain resource allocation field, modulation and coding scheme field, and new data indication field are non-common fields. The number of bits corresponding to cell 1 in the frequency domain resource allocation field in cell group 1 is different from the number of bits corresponding to cell 1 in cell group 2. The number of bits corresponding to cell 1 in the modulation and coding scheme field in cell group 1 is different from the number of bits corresponding to cell 1 in cell group 2. The number of bits corresponding to cell 1 in the new data indication field in cell group 1 is different from the number of bits corresponding to cell 1 in cell group 2.

[0090] For cell group 1, the second signaling indicates the number of bits corresponding to cell 1 in the frequency domain resource allocation field, which is 1 bit; the number of bits corresponding to cell 1 in the modulation and coding scheme field, which is 1 bit; and the number of bits corresponding to cell 1 in the new data indication field, which is 1 bit. For cell 2 in cell group 1, the number of bits corresponding to cell 2 in the frequency domain resource allocation field is 2 bits; the number of bits corresponding to cell 2 in the modulation and coding scheme field, which is 2 bits; and the number of bits corresponding to cell 2 in the new data indication field, which is 2 bits.

[0091] For cell group 2, the second signaling indicates the number of bits corresponding to cell 1 in the frequency domain resource allocation field, which is also 2 bits. The number of bits corresponding to cell 1 in the modulation and coding scheme field is also 2 bits. The number of bits corresponding to cell 1 in the new data indication field is also 2 bits. For cell 3 in cell group 2, the number of bits corresponding to cell 3 in the frequency domain resource allocation field is 3 bits; the number of bits corresponding to cell 3 in the modulation and coding scheme field is 3 bits; and the number of bits corresponding to cell 3 in the new data indication field is 3 bits.

[0092] like Figure 5 As shown, assuming the first field indicates the first DCI scheduling cell group 1, the first DCI includes the following fields: frequency domain resource allocation, modulation and coding scheme, and new data indication. The frequency domain resource allocation field is a common field, while the modulation and coding scheme field and the new data indication field are non-common fields. Since the frequency domain resource allocation field in this first DCI is a common field, the terminal device determines the length of the frequency domain resource allocation field in the first DCI to be 2 bits based on the candidate values ​​in the configuration information of the common fields of cell group 1 included in the first signaling. Since the modulation and coding scheme field and the new data indication field in this first DCI are non-common fields, the terminal device determines the length of the modulation and coding scheme field in the first DCI (i.e., 3 bits) by summing the number of bits corresponding to the modulation and coding scheme field configured for cell 1 by the second signaling (i.e., 1 bit) and the number of bits corresponding to the modulation and coding scheme field configured for cell 2 by the second signaling (i.e., 2 bits). The terminal device determines the length of the new data indication field in the first DCI (i.e., 3 bits) by summing the number of bits (1 bit) corresponding to the new data indication field configured for cell 1 by the second signaling and the number of bits (2 bits) corresponding to the new data indication field configured for cell 2 by the second signaling. In other words, the length of the common field is determined based on the candidate values ​​in the configuration information of the common field included in the first signaling, and the length of the non-common field is determined based on the number of bits corresponding to the non-common field configured separately for each cell by the second signaling.

[0093] In one possible implementation, the second signaling can indicate the number of bits corresponding to each cell in the non-common field in one or more cell groups in the following three ways:

[0094] Method 1: The second signaling includes the number of bits corresponding to each cell in the non-public field of one or more cell groups.

[0095] Method 1 allows you to directly indicate the number of bits corresponding to each cell in the non-public field within one or more cell groups.

[0096] Taking the example of the same cell in different cell groups occupying the same number of bits in the same non-common field. Assume the frequency domain resource allocation field, modulation and coding scheme field, and new data indication field are non-common fields. Cell group 1 includes cell 1 and cell 2, and cell group 2 includes cell 1 and cell 3. The second signaling can include the number of bits corresponding to cell 1 in the frequency domain resource allocation field, i.e., 1 bit; the number of bits corresponding to cell 2 in the frequency domain resource allocation field, i.e., 2 bits; and the number of bits corresponding to cell 3 in the frequency domain resource allocation field, i.e., 3 bits. The second signaling also includes the number of bits corresponding to cell 1 in the modulation and coding scheme field, i.e., 1 bit; the number of bits corresponding to cell 2 in the modulation and coding scheme field, i.e., 2 bits; and the number of bits corresponding to cell 3 in the modulation and coding scheme field, i.e., 3 bits. The second signaling also includes the number of bits corresponding to cell 1 in the new data indication field, i.e., 1 bit; the number of bits corresponding to cell 2 in the new data indication field, i.e., 2 bits; and the number of bits corresponding to cell 3 in the new data indication field, i.e., 3 bits.

[0097] Method 2: The second signaling includes the number of bits corresponding to the second cell in the non-public field and the field length difference information corresponding to each third cell. The second cell is one of one or more cell groups, and the third cell is one of one or more cell groups other than the second cell. The field length difference information corresponding to the third cell is used to indicate the difference between the number of bits corresponding to the third cell in the non-public field and the number of bits corresponding to the second cell in the non-public field. The second cell is the first cell.

[0098] Method 2 allows for the use of differential methods to indicate the number of bits corresponding to each cell in the non-public field within one or more cell groups.

[0099] Taking the example of the same cell in different cell groups occupying the same number of bits in the same non-common field. Assume the frequency domain resource allocation field, modulation and coding scheme field, and new data indication field are non-common fields. Cell group 1 includes cell 1 and cell 2, and cell group 2 includes cell 1 and cell 3. The second signaling may include the number of bits corresponding to cell 1 in the frequency domain resource allocation field, which is 1 bit; the difference between the number of bits corresponding to cell 2 and cell 1 in the frequency domain resource allocation field, which is 1 bit; and the difference between the number of bits corresponding to cell 3 and cell 1 in the frequency domain resource allocation field, which is 2 bits. The second signaling also includes the number of bits corresponding to cell 1 in the modulation and coding scheme field, which is 1 bit; the difference between the number of bits corresponding to cell 2 and cell 1 in the modulation and coding scheme field, which is 1 bit; and the difference between the number of bits corresponding to cell 3 and cell 1 in the modulation and coding scheme field, which is 2 bits. The second signaling also includes the number of bits corresponding to cell 1 in the new data indication field, which is 1 bit; the difference between the number of bits corresponding to cell 2 in the new data indication field and the number of bits corresponding to cell 1 in the new data indication field, which is 1 bit; and the difference between the number of bits corresponding to cell 3 in the new data indication field and the number of bits corresponding to cell 1 in the new data indication field, which is 2 bits.

[0100] Method 3: The second signaling includes the number of bits corresponding to the second cell in the non-public field and the field length difference information corresponding to each third cell. The second cell is one of one or more cell groups, and the third cell is one of one or more cell groups other than the second cell. The field length difference information corresponding to the third cell is used to indicate the difference between the number of bits corresponding to the third cell in the non-public field and the number of bits corresponding to the previous cell in the non-public field. The second cell is the first cell.

[0101] Method 3 allows for a different differential approach to indicate the number of bits corresponding to each cell in the non-public field within one or more cell groups.

[0102] Taking the example of the same cell in different cell groups occupying the same number of bits in the same non-common field. Assume the frequency domain resource allocation field, modulation and coding scheme field, and new data indication field are non-common fields. Cell group 1 includes cell 1 and cell 2, and cell group 2 includes cell 1 and cell 3.

The second signaling also includes the number of bits corresponding to cell 1 in the modulation and coding scheme field, which is 1 bit; the difference between the number of bits corresponding to cell 2 and cell 1 in the modulation and coding scheme field, which is 1 bit; and the difference between the number of bits corresponding to cell 3 and cell 2 in the modulation and coding scheme field, which is 1 bit. The second signaling also includes the number of bits corresponding to cell 1 in the new data indication field, which is 1 bit; the difference between the number of bits corresponding to cell 2 in the new data indication field and the number of bits corresponding to cell 1 in the new data indication field, which is 1 bit; and the difference between the number of bits corresponding to cell 3 in the new data indication field and the number of bits corresponding to cell 2 in the new data indication field, which is 1 bit.

[0103] Method 4: The second signaling includes the number of bits corresponding to the second cell in the non-common field of each cell group in one or more cell groups, and the field length difference information of each third cell corresponding to each cell group. The second cell corresponding to the cell group is one cell in the cell group, and the third cell corresponding to the cell group is the cell in the cell group other than the second cell. The field length difference information of the third cell corresponding to the cell group is used to indicate the difference between the number of bits corresponding to the third cell in the non-common field and the number of bits corresponding to the second cell corresponding to the cell group in the non-common field. The second cell is the first cell.

[0104] Taking the example of different numbers of bits occupied by the same cell in the same non-common field in different cell groups. Assume the frequency domain resource allocation field, modulation and coding scheme field, and new data indication field are non-common fields. Cell group 1 includes cell 1 and cell 2, and cell group 2 includes cell 1, cell 2, and cell 3.

The number of bits corresponding to Cell 1 in Cell Group 2 in the new data indication field is 2 bits; the difference between the number of bits corresponding to Cell 2 in Cell Group 2 and the number of bits corresponding to Cell 1 in Cell Group 2 in the new data indication field is 0 bits; the difference between the number of bits corresponding to Cell 3 in Cell Group 2 and the number of bits corresponding to Cell 1 in Cell Group 2 in the new data indication field is 1 bit.

[0106] Method 5: The second signaling includes the number of bits corresponding to the second cell in the non-common field of each cell group in one or more cell groups, and the field length difference information of each third cell corresponding to each cell group. The second cell corresponding to the cell group is one cell in the cell group, and the third cell corresponding to the cell group is the cell in the cell group other than the second cell. The field length difference information of the third cell corresponding to the cell group is used to indicate the difference between the number of bits corresponding to the third cell in the non-common field and the number of bits corresponding to the previous cell in the cell group in the non-common field. The second cell is the first cell.

[0107] Taking the example of different numbers of bits occupied by the same cell in the same non-common field in different cell groups. Assume the frequency domain resource allocation field, modulation and coding scheme field, and new data indication field are non-common fields. Cell group 1 includes cell 1 and cell 2, and cell group 2 includes cell 1, cell 2, and cell 3. For cell group 1, the second signaling can include the number of bits corresponding to cell 1 in the frequency domain resource allocation field, which is 1 bit; the difference between the number of bits corresponding to cell 2 in the frequency domain resource allocation field and the number of bits corresponding to cell 1 in the frequency domain resource allocation field, which is 1 bit. The number of bits corresponding to cell 1 in the modulation and coding scheme field, which is 1 bit; the difference between the number of bits corresponding to cell 2 in the modulation and coding scheme field and the number of bits corresponding to cell 1 in the modulation and coding scheme field, which is 1 bit. The number of bits corresponding to Cell 1 in Cell Group 1 in the New Data Indication field is 1 bit; the difference between the number of bits corresponding to Cell 2 in Cell Group 1 and the number of bits corresponding to Cell 1 in Cell Group 1 in the New Data Indication field is 1 bit.

[0108] For cell group 2, the second signaling may include the number of bits corresponding to cell 1 in the frequency domain resource allocation field, which is 2 bits; the difference between the number of bits corresponding to cell 2 in the frequency domain resource allocation field and the number of bits corresponding to cell 1 in the frequency domain resource allocation field, which is 0 bits; and the difference between the number of bits corresponding to cell 3 in the frequency domain resource allocation field and the number of bits corresponding to cell 2 in the frequency domain resource allocation field, which is 1 bit. The number of bits corresponding to cell 1 in the modulation and coding scheme field is 2 bits; the difference between the number of bits corresponding to cell 2 in the modulation and coding scheme field and the number of bits corresponding to cell 1 in the modulation and coding scheme field, which is 0 bits; and the difference between the number of bits corresponding to cell 3 in the modulation and coding scheme field and the number of bits corresponding to cell 2 in the modulation and coding scheme field, which is 1 bit. The number of bits corresponding to Cell 1 in Cell Group 2 in the new data indication field is 2 bits; the difference between the number of bits corresponding to Cell 2 in Cell Group 2 and the number of bits corresponding to Cell 1 in Cell Group 2 in the new data indication field is 0 bits; the difference between the number of bits corresponding to Cell 3 in Cell Group 2 and the number of bits corresponding to Cell 2 in Cell Group 2 in the new data indication field is 1 bit.

[0109] In one possible implementation, the length of the common fields corresponding to the one or more cell groups is the same, and / or the length of the non-common fields corresponding to the one or more cell groups is the same; or the total length of the DCI corresponding to the one or more cell groups is the same. This method can simplify the blind detection operation of the terminal device.

[0110] For example, assume that the time-frequency domain resource allocation field of DCI-scheduled cell group 1 is a common field, and the time-frequency domain resource allocation field of DCI-scheduled cell group 2 is also a common field. The length of the frequency domain resource allocation field corresponding to cell group 1 is the same as the length of the frequency domain resource allocation field corresponding to cell group 2.

[0111] For example, suppose the new data indication field is a non-common field when DCI schedules cell group 1, and suppose the new data indication field is a non-common field when DCI schedules cell group 2. The length of the new data indication field corresponding to cell group 1 is the same as the length of the new data indication field corresponding to cell group 2.

[0112] For example, suppose that the time-frequency domain resource allocation field of DCI-scheduled cell group 1 is a common field, while the modulation and coding scheme field and the new data indication field are non-common fields; and the time-frequency domain resource allocation field of DCI-scheduled cell group 2 is a common field, while the modulation and coding scheme field and the new data indication field are non-common fields. The length of the frequency domain resource allocation field corresponding to cell group 1 is the same as the length of the frequency domain resource allocation field corresponding to cell group 2; the length of the modulation and coding scheme field corresponding to cell group 1 is the same as the length of the modulation and coding scheme field corresponding to cell group 2; and the length of the new data indication field corresponding to cell group 1 is the same as the length of the new data indication field corresponding to cell group 2.

[0113] For example, suppose that when DCI schedules cell group 1, the total length of DCI is 10 bits, and when DCI schedules cell group 2, the total length of DCI is also 10 bits.

[0114] In one possible implementation, if the first field indicates that the first DCI schedules the first cell, the terminal device determines the length of each field in the first DCI according to existing methods.

[0115] It can be seen that, based on Figure 4 The described method can configure the public fields through the first signaling, and flexibly configure the information of the public fields in the DCI corresponding to the cell group.

[0116] Please see Figure 6 , Figure 6 This is a schematic diagram of a cell scheduling device provided in an embodiment of the present invention. The cell scheduling device can be a terminal device or a device with terminal device functions (e.g., a chip). Specifically, as shown...
