[0036] The information processing method, apparatus, communication device, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0037] Please see Figure 2 , Figure 2This is a flowchart illustrating an information processing method provided in an embodiment of this application. The method is executed by a communication device, which may be a terminal or a network-side device. Figure 2 As shown, the method includes the following steps:

[0038] Step 21: When L scheduling cells schedule the target cell, the communication equipment determines the size of the DCI for each scheduling cell, which is used to schedule the target cell.

[0039] In this embodiment, L is greater than or equal to 2, i.e., L≥2. Taking the target cell as the primary cell Pcell as an example, when the secondary cell Scell ​​is configured to schedule Pcell, Pcell is scheduled by both Scell ​​and Pcell simultaneously, and L equals 2 in this case.

[0040] Optionally, the L scheduling cells can satisfy at least one of the following conditions:

[0041] All are in the activated state;

[0042] All are in non-dormant state;

[0043] Each scheduled cell has a search space in its active bandwidth part (BWP) for scheduling target cells.

[0044] Optionally, the size of the DCI determined in step 21 satisfies at least one of the following:

[0045] The size of the DCI used for scheduling target cells in each scheduling cell satisfies the first condition; that is, for a scheduled target cell, the budget of the DCI size is defined according to each scheduling cell.

[0046] The size of the DCI used for scheduling target cells in L scheduling cells satisfies the first condition; that is, for a scheduled target cell, the budget of the DCI size is defined according to all scheduling cells.

[0047] In other words, when determining the size of the DCI for each scheduling cell, the communication equipment can determine the size of the DCI for each scheduling cell based on a first condition, so that the determined DCI size satisfies the corresponding first condition.

[0048] Optionally, the first condition above may include at least one of the following:

[0049] The number of different DCI sizes monitored by the terminal during PDCCH monitoring does not exceed the first value;

[0050] The number of different DCI sizes monitored by the terminal for PDCCH with specific identifier scrambling does not exceed the second value.

[0051] It should be noted that the first and / or second values ​​mentioned above can be selected based on actual needs, and can be the same or different, without limitation. For example, the first value is 4 and the second value is 3. The above-mentioned specific identifier can be selected as a specific Radio Network Temporary Identifier (RNTI), such as the Cell RNTI (C-RNTI).

[0052] The information processing method of this application embodiment, when L scheduling cells schedule a target cell, can determine the size of the DCI used for scheduling the target cell in each scheduling cell, where L≥2, and the size of the DCI satisfies at least one of the following: the size of the DCI used for scheduling the target cell in each scheduling cell satisfies a first condition; the size of the DCI used for scheduling the target cell in the L scheduling cells satisfies the first condition. Therefore, the requirement for DCI size when multiple cells schedule the same cell can be met.

[0053] In this embodiment of the application, when the size of the DCI used for scheduling the target cell in L scheduling cells satisfies a first condition, determining the size of the DCI of each scheduling cell may include: when a first field is defaulted to or configured to exist in the DCI of at least one of the L scheduling cells, it is determined that a first field exists in the DCI of the L scheduling cells, and the size of the first field in the DCI of each scheduling cell is determined to be N bits. That is, when the first field is defaulted to or configured to exist in the DCI of at least one of the L scheduling cells, the first field is defaulted to or forced to exist in the DCI of the L scheduling cells, meaning that the first field exists in the DCI of all scheduling cells, and the size of the first field is N bits. N is greater than 1.

[0054] Optionally, N can be determined based on at least one of the following:

[0055] Protocol predefined;

[0056] Network-side equipment, such as base station configuration;

[0057] The maximum value of the default or configured first field size in the DCI of at least one of the aforementioned scheduling cells.

[0058] Optionally, for the other scheduling cells among the L scheduling cells (excluding at least one), the first field in the DCI of these other scheduling cells is ignored by the terminal during DCI detection, and / or the first field in the DCI of these other scheduling cells is set to a predefined value or a configured value. In other words, when the DCI of a certain scheduling cell among the L scheduling cells is not configured or does not require the function corresponding to the first field, the terminal will ignore the first field in that DCI during DCI detection, and / or the value of the first field in that DCI will be set to a predefined value or a configured value.

[0059] For example, for network-side devices, if the first field exists by default or is configured in the DCI of at least one of the L scheduling cells, the network-side devices can configure all the DCIs of the L scheduling cells to have the first field. The value of the first field in the DCIs of the other scheduling cells among the L scheduling cells, except for at least one scheduling cell, is set to a predefined value or a configuration value, and the configured DCI is sent to the terminal.

[0060] For example, for a terminal, if the DCI of at least one of the L scheduling cells has a first field by default or in configuration, the terminal determines that the DCI of all L scheduling cells has a first field. The value of the first field in the DCI of the other scheduling cells (excluding at least one scheduling cell) is set to a predefined value or a configuration value, and the first field in the DCI of the other scheduling cells is ignored when performing DCI detection.

[0061] Optionally, when the first field of the DCI required by the first scheduling cell among the L scheduling cells is M bits in size, and M is less than N, the preset M bits of the first field in the DCI of the first scheduling cell are used for functional indication, and the other NM bits of the first field, excluding the preset M bits, are set to a first preset value. This first preset value can be set based on actual needs, such as 0. The first scheduling cell can be any cell among the L scheduling cells that meets the corresponding conditions, and there is no limitation on this.

[0062] Optionally, the aforementioned preset M bits can be any of the following: the first M bits of the N bits in the first field; or the last M bits of the N bits in the first field.

[0063] For example, when the DCI of a certain scheduling cell requires the size M of the first field to be less than the determined size N of the first field, the UE can use the high M bits or the low M bits to indicate the function of the first field, and set the other NM bits to a specific value such as 0.

[0064] Optionally, the first field described above may include at least one of the following:

[0065] Carrier Indication Field (CIF);

[0066] Transmission configuration indication field;

[0067] Scell ​​dormancy indication field;

[0068] Bit fields added during DCI size alignment.

[0069] In some embodiments, for DCI 0_1 or DCI 1_1, when the cell scheduled by the DCI is not the same cell as its own cell (i.e., cross-carrier scheduling), the CIF field of the DCI is 3 bits; when the cell scheduled by the DCI is the same cell as its own cell (i.e., self-scheduling), the existence of the CIF field of the DCI depends on the configuration parameters of the Radio Resource Control (RRC) signaling for self-scheduling.

[0070] In some embodiments, for DCI 0_1 or DCI 1_1, the Scelldormancy indication field of DCI exists when the following conditions are met simultaneously, and its size is determined according to the number of cell groups configured in the secondary cell Scell: 1) DCI is transmitted during the active time of Discontinuous Reception (DRX) in the primary cell Pcell; 2) At least one Scell ​​is configured with dormancyGroupWithinActiveTime; 3) At least one Scell ​​is configured with more than two downlink DL BWPs.

[0071] In some embodiments, for DCI 1_1, the Transmission configuration indication field of the DCI is configured in each control resource set (Coreset) of the BWP in the scheduling cell. When the configurations in multiple Coresets of a BWP are different, the size of this field is different, for example, 0 or 3 bits. When multiple search spaces on a BWP are associated with different Coresets, the size of DCI 1_1 needs to be padded with zeros to unify it to the largest size.

[0072] In this embodiment, when the budget for the DCI size is defined according to all scheduled cells, different DCI sizes of the same DCI format in different scheduled cells can be considered as one DCI size. For L scheduled cells whose DCI sizes for scheduling the target cell satisfy the first condition, when the DCI sizes of different scheduled cells with the same DCI format (e.g., DCI 0_1 or DCI 1_1) are different, the DCI sizes of these different scheduled cells are considered the same. That is, for different scheduled cells with the same DCI format, even if the determined DCI sizes are different, they are treated as the same DCI size for determining whether the first condition is met.

[0073] Optionally, when the DCI size budget is defined according to all scheduled cells, the DCI size of different scheduled cells with the same DCI format can be controlled to be the same. That is, if the DCI size of the target cell used for scheduling in L scheduled cells satisfies the first condition, when determining the DCI size of the target cell used for scheduling in each scheduled cell, if the DCI sizes of different scheduled cells under the first DCI format in the L scheduled cells are different when initially determined, the DCI size of all scheduled cells under the first DCI format can be determined to be a third value, so that the DCI sizes of all scheduled cells under the first DCI format are aligned. The first DCI format is, for example, DCI 1_1 or DCI 0_1, etc.

[0074] The third value can be the maximum value among the DCI sizes of all scheduled cells under the initially determined first DCI format, or it can be a second preset value. This second preset value can be set based on actual needs; it can be configured / defined for each DCI format, or it can be configured / defined for all DCI formats, or it can be the maximum value among the DCI sizes under all DCI formats. There are no restrictions on this.

[0075] In some embodiments, for the same DCI format in different scheduling cells, if the initially determined DCI size is different, the DCI size of all scheduling cells under this DCI format is determined to be the preset value or the maximum value among the initially determined DCI sizes. The insufficient part can be supplemented by adding specific values, such as 0, to the first or last bit.

[0076] Optionally, when the budget for the DCI size is defined according to all scheduled cells, the DCI size of the same DCI format in different scheduled cells can be controlled to be the same. That is, if the DCI size of the target cell of the L scheduled cells meets the first condition, determining the DCI size of the target cell for each scheduled cell can include: determining the initial DCI size of each scheduled cell for the target cell; then, if the initial DCI size of the L scheduled cells does not meet the first condition under the initial DCI size, adjusting the DCI size of each scheduled cell for the target cell so that the DCI size of the L scheduled cells for the target cell meets the first condition.

[0077] Optionally, the process of adjusting the DCI size for each scheduling cell used to schedule the target cell may include: when the DCI sizes of different scheduling cells under the second DCI format in the L scheduling cells are different when initially determined, determining the DCI size of all scheduling cells under the second DCI format to a fourth value, so that the DCI sizes of all scheduling cells under the second DCI format are aligned. The second DCI format is, for example, DCI 1_1 or DCI 0_1, etc.

[0078] The fourth value can be the maximum value among all scheduled cells under the initially determined second DCI format, or it can be a third preset value. This third preset value can be set based on actual needs; it can be configured / defined for each DCI format, or it can be configured / defined for all DCI formats, or it can be the maximum value among all DCI formats. There is no limitation on this.

[0079] In some embodiments, when adjusting the DCI size, if the initially determined DCI size is different for one or more specific DCI formats of different scheduling cells, the DCI size of all scheduling cells under that DCI format is adjusted to a preset value or the maximum value among the initially determined DCI sizes. The insufficient part can be supplemented by adding a specific value, such as 0, to the first or last bit.

[0080] The present application will now be described in conjunction with specific embodiments.

[0081] Example 1

[0082] When the same cell is scheduled by multiple cells, or when an Scell ​​schedules a Pcell configuration (i.e., a Pcell is scheduled by both an Scell ​​and a Pcell simultaneously), the process for confirming the DCI size and DCI size alignment is performed independently for each scheduled cell. Finally, the DCI size of each scheduled cell is confirmed to meet the following conditions:

[0083] For each scheduling target cell, the UE does not expect the number of different DCI sizes for PDCCH monitoring to exceed 4, nor does it expect the number of different DCI sizes for PDCCH monitoring with C-RNTI scrambling to exceed 3.

[0084] Example 2

[0085] When the same cell is scheduled by multiple cells, or when an Scell ​​schedules a Pcell configuration (i.e., a Pcell is scheduled by both an Scell ​​and a Pcell simultaneously), the process of confirming the DCI size and DCI size alignment is performed independently for each scheduled cell. For the same DCI format in different scheduled cells, even if the determined DCI sizes are different, they are treated as a single DCI size to determine whether the following conditions are met:

[0086] For the target cell being scheduled, i.e. all scheduled cells, the UE does not expect the number of different DCI sizes for PDCCH monitoring to exceed 4, nor does it expect the number of different DCI sizes for PDCCH monitoring with C-RNTI scrambling to exceed 3.

[0087] Example 3

[0088] When the same cell is scheduled by multiple cells, or when an Scell ​​schedules a Pcell configuration (i.e., a Pcell is scheduled by both an Scell ​​and a Pcell simultaneously), the initial DCI size is determined independently for each scheduled cell. For the same DCI format in different scheduled cells, if the initially determined DCI sizes are different, the DCI size for that DCI format in all scheduled cells is the maximum value among the initially determined DCI sizes. Any shortfall is filled by padding with a specific value (e.g., 0) in the first or last bit. The resulting DCI size is then used to determine whether it meets the following conditions:

[0089] For the target cell being scheduled, i.e. all scheduled cells, the UE does not expect the number of different DCI sizes for PDCCH monitoring to exceed 4, nor does it expect the number of different DCI sizes for PDCCH monitoring with C-RNTI scrambling to exceed 3.

[0090] Example 4

[0091] When the same cell is scheduled by multiple cells, or when an Scell ​​schedules a Pcell configuration (i.e., a Pcell is scheduled by both an Scell ​​and a Pcell simultaneously), for some special fields in the DCI, it is necessary to combine the situation of multiple scheduled cells to determine the size of these fields in the DCI of each scheduled cell, and finally determine the DCI size of each scheduled cell.

[0092] For example, for the CIF field in DCI, the DCI1_1 / 0_1 of all cells (e.g., Pcell and Scell) of the scheduling target cell have a CIF field.

[0093] For example, for the Transmission configuration indication field in DCI, the size of the Transmission configuration indication field in DCI 1_1 of all cells of the scheduling target cell (e.g., Pcell and Scell) is the same, which is the maximum value among the sizes of the Transmission configuration indication fields determined on at least one scheduling cell.

[0094] For example, the Scell ​​dormancy indication field in DCI exists and is the same size in DCI 1_1 for all cells of the scheduling target cell (e.g., Pcell and Scell).

[0095] For example, if one of the scheduling cells adds 1 bit to DCI 0_1 / DCI 0_1 during DCI size alignment to distinguish different DCI formats, then 1 bit is added to DCI 0_1 / 1_1 for all scheduling cells (e.g., Pcell and Scell). For instance, if the non-Fallback DCI0_1 of a user-specific search space (USS) is the same size as the fallback DCI of other USSs, then 1 bit of 0 can be added after DCI 0_1; conversely, if the non-Fallback DCI 1_1 of a USS is the same size as the fallback DCI of other USSs, then 1 bit of 0 can be added after DCI 1_1.

[0096] Example 5

[0097] When the same cell configuration is scheduled by L cells (L≥2), and the L cells are in activated or non-dormant states, the DCI budget is defined based on the assumption that the target cell is scheduled by L cells. Specifically, when Scell ​​is configured to schedule Pcell (i.e., Pcell is scheduled by both Pcell and Scell), if Scell ​​switches to deactivated or dormant state, the DCI budget is adjusted to the scenario where Pcell is only scheduled by Pcell.
