[0016] Hereinafter, in combination with the drawings of the embodiments of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described. Obviously, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present disclosure.

[0018] In the embodiments of the present disclosure, terms such as first, second, third, etc. may be used to describe various information, but it should be understood that this information should not be limited to these terms. These terms are only used to distinguish the same type of information.

[0020] FIG. 1 is a flowchart of a cell determination method according to an embodiment of the present disclosure. The cell determination method shown in this embodiment is executed by a terminal, and the terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, IoT devices, etc. The terminal can communicate with network devices including, but not limited to, base stations and core networks in communication systems such as 4G, 5G, 6G, etc.

[0021] As shown in Figure 1, the cell determination method may include the following steps: In step S101, at least one set of cells corresponding to downlink control information for scheduling multiple cells is determined. In step S102, for each first cell set among the at least one cell set, a reference cell in the first cell set is determined, and the downlink control information for scheduling the plurality of cells is determined to determine the blind check resource that is occupied when scheduling the cells in the first cell set.

[0022] In one embodiment, if the at least one cell set includes multiple cell sets, the multiple cell sets may or may not contain the same cell.

[0023] In one embodiment, downlink control information for scheduling multiple cells can be abbreviated as, for example, MC-DCI, which is used to schedule multiple cells and specifically refers to data for scheduling multiple cells, such as PUSCH, PDSCH, etc., for scheduling one or more cells among multiple cells, thereby realizing the scheduling of multiple cells via a single DCI. Here, MC stands for Multi-cell.

[0024] In one embodiment, the format of the downlink control information for scheduling multiple cells may be the same as the legacy DCI format (e.g., DCI format 0_0, DCI format 0_1, etc.), or a newly defined format, such as DCI format 0_3, DCI format 1_3, etc., may be used.

[0025] In one embodiment, downlink control information for scheduling multiple cells can be scrambled with a Radio Network Temporary Identity (RNTI), for example, with a cell radio network temporary identifier C-RNTI, or with a newly defined RNTI.

[0026] Downlink control information for scheduling multiple cells can be used to schedule multiple cells, and compared to DCI for scheduling a single cell in legacy DCI, the information in downlink control information for scheduling multiple cells is relatively larger, and consequently, the blind check resources occupied are also relatively larger. A terminal can receive downlink control information for scheduling multiple cells (scheduled cells) used to schedule multiple cells in a scheduling cell, but if all occupied blind check resources are determined based on the scheduling cell, it becomes too burdensome for the scheduling cell and is detrimental to ensuring good blind check efficiency and blind check performance.

[0027] According to embodiments of the present disclosure, a terminal can determine at least one set of cells corresponding to downlink control information for scheduling multiple cells, then determine a reference cell in the first set of cells for each of the first set of cells, and further determine the blind check resource occupied by the downlink control information for scheduling multiple cells at the reference cell in the first set of cells when the downlink control information for scheduling multiple cells subsequently schedules a cell in the first set of cells.

[0028] For example, if at least one cell set includes a first cell set set#1, a first cell set set#2, etc., it is possible to determine the reference cell Cell#1 in set#1 and the reference cell Cell#2 in set#2. Furthermore, if downlink control information for scheduling multiple cells is subsequently received, and it is determined that the downlink control information for scheduling multiple cells will be used to schedule multiple cells in set#1, it is possible to determine the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#1. If it is determined that the downlink control information for scheduling multiple cells will be used to schedule multiple cells in set#2, it is possible to determine the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#2.

[0029] Downlink control information for scheduling multiple cells can schedule multiple cells, for example, it can schedule multiple cells in a first cell set. In this embodiment, a reference cell in the first cell set can be determined, and the downlink control information for scheduling multiple cells in the reference cell can determine the blind check resources occupied when scheduling cells in the first cell set, or a proportional coefficient can be introduced to determine the blind check resources, which is advantageous for the terminal to ensure blind check efficiency and blind check performance for downlink control information and to guarantee fairness in the allocation of blind check resources.

[0030] Here, after determining the reference cell, the terminal can determine the settings for the Search Space (SS) and / or the Control Resource Set (CORESET) corresponding to the downlink control information for scheduling multiple cells set in the reference cell. Furthermore, based on the SS and / or CORESET settings, it can determine the blind check resources occupied by the downlink control information for scheduling multiple cells. For example, the blind check determines the time-domain field resources and frequency-domain field resources of the downlink control information for scheduling multiple cells. The blind check then calculates the blind check resources occupied by all DCIs (e.g., downlink control information for scheduling multiple cells and legacy DCIs) that include the downlink control information for scheduling multiple cells in a slot or time span of the downlink control information for scheduling multiple cells.

[0031] Note that the reference cell in the first set of cells may be a single cell or multiple cells; these two cases will be explained later with examples.

[0032] In one embodiment, the blind check resource is Candidate Physical Downlink Control Channel (PDCCH) candidates, and It includes at least one Control Channel Element (CCE).

[0033] Here, determining the blind check resources means determining the number of blind check resources. For example, for the two types of blind check resources mentioned above, this means determining the number of blind check resources, at least one of the PDCCH candidates or CCEs, that occupy a certain time domain field range, for example, within one slot range or one PDCCH span range. The blind check resources determined by this disclosure are not limited to the PDCCH candidates or CCEs mentioned above, and other blind check resources may be determined as needed. For example, the determined blind check resources may further include blind checks (Blind Decoding, BD), where BD refers to the number of PDCCH candidates that occupy a certain length of time.

[0034] The following describes, by some embodiment, a method for determining a reference cell in the first cell set. Here, the method for determining a reference cell in the first cell set can be determined based on predefined rules (e.g., protocol agreements), or based on instructions from a network device, and the disclosure is not limited thereto.

[0035] Figure 2 is a flowchart of another cell determination method according to an embodiment of the present disclosure. As shown in Figure 2, the step of determining a reference cell in the first cell set includes the following steps: In step S201, the reference cell in the first cell set is determined based on the cell identifier.

[0036] In one embodiment, when determining a reference cell in a first set of cells, first, the cell identifier (Cell ID) of each cell in the first set of cells is determined, and then, based on the cell identifier of each cell, a reference cell can be selected in the set of cells included in the first set of cells.

[0037] In one embodiment, the step of determining a reference cell in the first cell set based on the cell identifier is: If the reference cell in the first cell set contains one cell, the step of determining the cell with the largest cell identifier or the cell with the smallest cell identifier in the first cell set as the reference cell, or If a reference cell in the first cell set includes multiple cells, the method includes the step of determining multiple cells in the first cell set as reference cells in the first cell set in descending order of their identifiers, or determining multiple cells in the first cell set as reference cells in ascending order of their cell identifiers.

[0038] In one embodiment, if the reference cell in the first cell set contains one cell, determining the reference cell in the first cell set based on the cell identifier can be done by determining the cell with the largest cell identifier as the reference cell in the first cell set, or by determining the cell with the smallest cell identifier as the reference cell in the first cell set.

[0039] For example, the first set of cells includes cells Cell#1 (Cell ID is 1), Cell#2 (Cell ID is 2), Cell#3 (Cell ID is 3), and Cell#4 (Cell ID is 4). When the cell with the largest cell identifier is determined as the reference cell in the first set of cells, Cell#4 can be determined as the reference cell in the first set of cells. When the cell with the smallest cell identifier is determined as the reference cell in the first set of cells, Cell#1 can be determined as the reference cell in the first set of cells.

[0040] In one embodiment, if a reference cell in the first cell set includes multiple cells, determining the reference cell in the first cell set based on the cell identifier can be done by determining multiple cells in the first cell set in descending order of identifier as the reference cell in the first cell set, or by determining multiple cells in the first cell set in ascending order of cell identifier as the reference cell in the first cell set.

[0041] For example, the first set of cells contains Cell#1 (Cell ID is 1), Cell#2 (Cell ID is 2), Cell#3 (Cell ID is 3), and Cell#4 (Cell ID is 4), and has 2 reference cells. When the cell with the largest cell identifier is determined as the reference cell in the first set of cells, Cell#4 and Cell#3 can be determined as reference cells in the first set of cells. When the cell with the smallest cell identifier is determined as the reference cell in the first set of cells, Cell#1 and Cell#2 can be determined as reference cells in the first set of cells.

[0042] In one embodiment, the cells in a first cell set can be sorted in a first order (for example, determined based on a predefined rule or based on network instructions), and then a reference cell in the first cell set can be determined based on the sort number of the cells. For example, the first order may include, but is not limited to, the order of cell identifiers in ascending order, the order of cell identifiers in ascending order, or the order of blind check resources corresponding to the DCI set for each cell, where the method for determining the blind check resources corresponding to the DCI set for each cell will be described below.

[0043] Let's take the example of a first cell set containing four cells: Cell#1, Cell#2, Cell#3, and Cell#4. For instance, the first sorting order is performed by sorting the cells in descending order according to their Cell IDs, resulting in Cell#4, Cell#3, Cell#2, and Cell#1. For example, if we determine that the cell with sort number 3 is the reference cell of the first cell set, and we know that Cell#2 is the cell with sort number 3, we can then determine that Cell#2 is the reference cell of the first cell set.

[0044] Figure 3 is a flowchart of a cell determination method according to an embodiment of the present disclosure. As shown in Figure 3, the step of determining a reference cell in the first cell set includes step S301, In step S301, the reference cell in the first cell set is determined based on the blind check resources occupied by the DCI set in each cell of the first cell set.

[0045] In one embodiment, when determining a reference cell in a first cell set, DCI can first determine the blind check resources occupied by each cell in the first cell set, and then determine the reference cell in the first cell set based on the blind check resources occupied by DCI in each cell in the first cell set.

[0046] In one embodiment, the step of determining a reference cell in the first cell set is based on the blind check resources occupied by the DCI set for each cell in the first cell set. If the reference cell in the first cell set contains one cell, the step of determining the cell in the first cell set that has the fewest blind check resources occupied by DCI is the reference cell in the first cell set, or If the reference cell in the first cell set includes multiple cells, the process includes determining multiple cells in the first cell set as reference cells in the first cell set, in ascending order of the number of blind check resources occupied by DCI (which is the DCI set for each cell in the first cell set).

[0047] Here, the blind check resources occupied by the DCI configured for each cell may be the blind check resources occupied by the legacy DCI configured for each cell, or they may be the blind check resources occupied by all DCI configured for each cell (for example, including legacy DCIs and downlink control information for scheduling multiple cells).

[0048] In one embodiment, taking the legacy DCI set for each cell as an example, if the legacy DCI set for a cell occupies a large number of blind check resources, then under certain conditions, the number of blind check resources corresponding to the DCI set for a cell will be small, and the number of blind check resources occupied by the downlink control information for scheduling multiple cells will be small. Therefore, if the reference cell in the first cell set contains one cell, first, the number of blind check resources occupied by the legacy DCI set for each cell in the first cell set can be determined, and then the cell with the fewest blind check resources occupied by the legacy DCI can be determined as the reference cell in the first cell set. This is advantageous in ensuring the blind check capability of the downlink control information for scheduling multiple cells in the reference cell of the terminal.

[0049] In one embodiment, taking the blind check resources occupied by all DCIs set for each cell as an example, the fewer the blind check resources occupied by all DCIs set for a cell, the lower the complexity of the terminal's blind check. Therefore, if the reference cell in the first cell set contains one cell, first, the blind check resources occupied by all DCIs set for each cell in the first cell set can be determined, and then the cell with the fewest blind check resources occupied by all DCIs can be determined as the reference cell in the first cell set. This is advantageous in reducing the complexity of the terminal's blind check on the reference cell.

[0050] For example, the first set of cells includes cells Cell#1, Cell#2, Cell#3, and Cell#4. For these four cells, the blind check resources occupied by the DCI set for each cell can be determined to be, for example, R1 for the DCI set for Cell#1, R2 for the DCI set for Cell#2, R3 for the DCI set for Cell#3, and R4 for the DCI set for Cell#4. The order of these four blind check resources from smallest to largest is R2, R3, R4, and R1. In other words, the DCI set for Cell#2 has the smallest blind check resource R2, so Cell#2 can be selected as the reference cell. Downlink control information for scheduling multiple cells is used to determine which blind check resources are occupied.

[0051] In embodiments of this disclosure, determining the blind check resources occupied by the DCI set up for a given cell includes, but is not limited to, the following two methods: Method 1: Determine the search space set for the cell, and sum all blind check resources (e.g., PDCCH candidates) of the DCI set in the search space. Method 2: Determine the search space set up for the cell and sum the blind check resources of the corresponding DCI within a specific time unit in the search space. Here, the specific time unit may be defined by a predefined rule or indicated by a network device, and may be one or more frames and / or one or more subframes and / or one or more slots and / or one or more symbols and / or one or more PDCCH spans.

[0052] In one embodiment, taking the legacy DCI set for each cell as an example, the legacy DCI set for a cell occupies a large number of blind check resources, so the downlink control information for scheduling multiple cells occupies fewer blind check resources. Therefore, if the reference cell in the first cell set includes multiple cells, first, the blind check resources occupied by the legacy DCI set for each cell in the first cell set can be determined, and then multiple cells in the first cell set can be determined as reference cells in the first cell set in ascending order of the blind check resources occupied by the legacy DCI. This is advantageous in ensuring the blind check capability of the downlink control information for scheduling multiple cells in the reference cell of the terminal.

[0053] In one embodiment, taking the blind check resources occupied by all DCIs set for each cell as an example, the fewer the blind check resources occupied by all DCIs set for a cell, the relatively lower the complexity of the terminal's blind check. Therefore, if the reference cell in the first cell set includes multiple cells, first, the blind check resources occupied by all DCIs set for each cell in the first cell set can be determined, and then multiple cells in the first cell set can be determined as reference cells in the first cell set in ascending order of the blind check resources occupied by all DCIs. This is advantageous in ensuring the ability to blind check downlink control information for scheduling multiple cells in the terminal's reference cell.

[0054] For example, the number of reference cells is 2, and the first cell set includes cells Cell#1, Cell#2, Cell#3, and Cell#4. For these four cells, it can be determined that the blind check resources occupied by the DCI set for each cell are, for example, R1 for the DCI set for Cell#1, R2 for the DCI set for Cell#2, R3 for the DCI set for Cell#3, and R4 for the DCI set for Cell#4. The order of these four blind check resources from smallest to largest is R2, R3, R4, and R1. That is, the blind check resource R2 occupied by the DCI set for Cell#2 is the smallest, followed by the blind check resource R3 occupied by the DCI set for Cell#3. Next, Cell#2 and Cell#3 can be selected as reference cells, and downlink control information for scheduling multiple cells is used to determine the blind check resources occupied. Determining the blind check resources occupied by the DCI set in the aforementioned cell has already been explained above and will not be explained further here.

[0055] In one embodiment, the DCI is Conventional DCI, i.e. legacy DCI, includes at least one of DCI 0_0, DCI 0_1, DCI 1_0, DCI 1_1, DCI 2_0, DCI 2_1, etc. All DCIs set in the aforementioned cell include, for example, legacy DCIs and downlink control information for scheduling multiple cells.

[0056] Figure 4 is a flowchart of another cell determination method according to an embodiment of the present disclosure. As shown in Figure 4, the step of determining a reference cell in the first cell set includes step S401, In step S401, a cell is determined as a reference cell in the first cell set for determining the size budget of downlink control information for scheduling the plurality of cells in the first cell set.

[0057] In one embodiment, when downlink control information for scheduling multiple cells schedules multiple cells in a first set of cells, at least one cell in the multiple cells can determine the budget for the size (i.e., the number of bits occupied) of the downlink control information for scheduling the multiple cells, and at least one cell specifically aligns the size of the DCI (DCI containing the downlink control information for scheduling the multiple cells) (this is an inference alignment process for the terminal side).

[0058] Then, when selecting a reference cell, at least one cell can be selected as the reference cell to determine the size budget of the downlink control information for scheduling the multiple cells, and in the process of scheduling the multiple cells using downlink control information for scheduling the multiple cells, the decision actions performed by the cells that need to be scheduled can be concentrated on a single cell, which is advantageous in simplifying the setting logic for the cells.

[0059] Figure 5 is a flowchart of another cell determination method according to an embodiment of the present disclosure. As shown in Figure 5, the step of determining a reference cell in the first cell set includes step S501, In step S501, a cell in the first cell set that has a search space set corresponding to downlink control information for scheduling the plurality of cells is determined to be the reference cell in the first cell set.

[0060] In one embodiment, when determining a reference cell in a first cell set, first, a search space corresponding to downlink control information for scheduling multiple cells that schedule cells in the first cell set can be determined, and then a cell in the first cell set that has a search space corresponding to the downlink control information for scheduling the multiple cells set up can be determined as the reference cell. For example, if the search space is SS#1, that is, an SS with identifier 1, then a cell (which may be one or more cells) in the first cell set that has an SS identified as 1 can be determined as the reference cell.

[0061] Furthermore, the embodiments for determining the reference cell in several of the first cell sets described above can be implemented individually and combined as needed. For example, it is possible to determine a cell in the first cell set that has a search space set up corresponding to downlink control information for scheduling multiple cells. If multiple cells have been determined, it is possible to further determine the cell with the fewest blind check resources occupied by the DCI set up in each of the multiple cells as the reference cell.

[0062] Figure 6 is a flowchart of another cell determination method according to an embodiment of the present disclosure. As shown in Figure 6, when the reference cell in the first cell set includes multiple cells, the step of determining the blind check resources occupied by the downlink control information for scheduling the multiple cells in the reference cell in the first cell set when scheduling the cells in the first cell set includes the following steps: In step S601, the downlink control information for scheduling multiple cells set in each of the reference cells in the first cell set is determined, and the blind check resources occupied by each of these cells are determined.

[0063] In one embodiment, if a reference cell includes multiple cells, each of these cells can determine the blind check resources occupied by the downlink control information for scheduling the multiple cells.

[0064] Let's take the example where the first set of cells includes Cell#1, Cell#2, Cell#3, and Cell#4.

[0065] If the determined reference cells are Cell#1 and Cell#2, it is possible to determine the blind check resources occupied by downlink control information for scheduling multiple cells in Cell#1, and it is also possible to determine the blind check resources occupied by downlink control information for scheduling multiple cells in Cell#2.

[0066] If all cells in the first cell set are determined to be reference cells, then the blind check resources occupied by downlink control information for scheduling multiple cells can be determined in Cell#1, the blind check resources occupied by downlink control information for scheduling multiple cells can be determined in Cell#2, the blind check resources occupied by downlink control information for scheduling multiple cells can be determined in Cell#3, and the blind check resources occupied by downlink control information for scheduling multiple cells can be determined in Cell#4.

[0067] In one embodiment, the step of determining the blind check resources occupied by downlink control information for scheduling a plurality of cells set in each of the reference cells in the first cell set includes the step of determining the blind check resources based on the determination result and quantization coefficients in each of the cells.

[0068] When determining the blind check resources occupied by downlink control information for scheduling multiple cells set in each of the reference cells in the first cell set, the determination result for each cell (i.e., the determined blind check resource) can be processed by a quantization coefficient (for example, by performing algorithmic processing such as multiplying, dividing, adding, subtracting, squaring, or taking the logarithm of the determination result based on the quantization coefficient) to obtain the final blind check resource. For example, the determination result for a certain cell can be multiplied by a quantization coefficient to obtain the final determined blind check resource for that cell.

[0069] In one embodiment, the quantization coefficient is determined based on the number of cells (e.g., all or some cells in a first cell set) contained in the reference cell, for example, the quantization coefficient may be 1 / K, where K is the number of cells contained in the reference cell. This is advantageous in reducing the overall burden of determining the blind check resources occupied by downlink control information for scheduling multiple cells in multiple cells.

[0070] Let's take the example where the first set of cells includes Cell#1, Cell#2, Cell#3, and Cell#4.

[0071] If the determined reference cells are Cell#1 and Cell#2, the quantization coefficient is 1 / 2. Decision result A, which determines the blind check resource occupied by the downlink control information for scheduling multiple cells in Cell#1, can be multiplied by 1 / 2 to obtain A / 2, which can be used as the blind check resource occupied by the downlink control information for scheduling multiple cells determined in Cell#1. Decision result B, which determines the blind check resource occupied by the downlink control information for scheduling multiple cells in Cell#2, can be multiplied by 1 / 2 to obtain B / 2, which can be used as the blind check resource occupied by the downlink control information for scheduling multiple cells determined in Cell#1.

[0072] If the determined reference cells are Cell#1, Cell#2, Cell#3, and Cell#4, the quantization coefficient is 1 / 4. Decision result A, which determines the blind check resource occupied by downlink control information for scheduling multiple cells in Cell#1, can be multiplied by 1 / 4 to obtain A / 4, which can be used as the blind check resource occupied by downlink control information for scheduling multiple cells determined in Cell#1. Decision result B, which determines the blind check resource occupied by downlink control information for scheduling multiple cells in Cell#2, can be multiplied by 1 / 4 to obtain B / 4, which can be used as the blind check resource occupied by downlink control information for scheduling multiple cells determined in Cell#1. Decision result C, which determines the blind check resource occupied by downlink control information for scheduling multiple cells in Cell#3, can be multiplied by 1 / 4 to obtain C / 4, which can be used as the blind check resource occupied by downlink control information for scheduling multiple cells determined in Cell#3. Decision result D, which determines the blind check resource occupied by downlink control information for scheduling multiple cells in Cell#4, can be multiplied by 1 / 4 to obtain D / 4, which can be used as the blind check resource occupied by downlink control information for scheduling multiple cells determined in Cell#4.

[0073] In one embodiment, if the at least one cell set includes multiple cell sets and there are intersecting cells between the multiple cell sets, and if the multiple first cell sets include the same reference cell, then downlink control information for scheduling the multiple cells with the same reference cell determines the blind check resources to be occupied when scheduling cells in each of the multiple first cell sets.

[0074] In one embodiment, if at least one cell set is present in multiple cell sets, then the multiple cell sets may have intersecting cells (containing the same cell) and may not have intersecting cells (not containing the same cell).

[0075] For example, let's consider two sets of cells.

[0076] If cell set #1 is {Cell #1, Cell #2, Cell #3} and cell set #2 is {Cell #1, Cell #4, Cell #5}, then there is an intersection {Cell #1} between set #1 and set #2, and the intersecting cell is Cell #1.

[0077] If cell set #1 is {Cell #1, Cell #2, Cell #3} and cell set #3 is {Cell #4, Cell #5, Cell #6}, then there is no intersection between set #1 and set #3.

[0078] When there are intersecting cells between multiple sets of cells, the same reference cell can be determined when determining a reference cell for each first set of cells among the multiple sets. In this case, the blind check resources occupied by the downlink control information for scheduling multiple cells can be determined when scheduling cells in each first set of cells that intersect with that same reference cell. In this case, the blind check resources occupied by the downlink control information for scheduling multiple cells determined by the same reference cell are the sum of the blind check resources occupied by the downlink control information for scheduling multiple cells determined for each first set of cells.

[0079] For example, if it is determined that the reference cell in set#1 is Cell#1, and the reference cell in set#2 is also Cell#1, and Cell#1 is the same reference cell, then the downlink control information for scheduling multiple cells in Cell#1 determines the blind check resource occupied by the downlink control information for scheduling multiple cells when scheduling multiple cells in set#1, for example, A, and the downlink control information for scheduling multiple cells in Cell#1 determines the blind check resource occupied by the downlink control information for scheduling multiple cells when scheduling multiple cells in set#2, for example, B. The blind check resource occupied by the downlink control information for scheduling multiple cells determined in Cell#1 is the sum of A and B.

[0080] In embodiments of this disclosure, determining the blind check resources occupied by downlink control information for scheduling multiple cells set for a given cell includes, but is not limited to, the following two methods: Method 1: Determine the search space set for the cell, and sum all blind check resources (e.g., PDCCH candidates) of the downlink control information for scheduling multiple cells within the search space. Method 2: Determine the search space set up for the cell and sum up the blind-check resources of downlink control information for scheduling multiple cells within a specific time unit in the search space. Here, the specific time unit may be defined by a predefined rule or indicated by a network device, and may be one or more frames and / or one or more subframes and / or one or more slots and / or one or more symbols.

[0081] In one embodiment, if the at least one cell set includes multiple cell sets and intersecting cells exist between the multiple cell sets, the step of determining the reference cell in the first cell set for each first cell set of the at least one cell set is: A step of determining a reference cell in a first cell set for each of the multiple first cell sets, wherein the reference cell in each first cell set includes different steps.

[0082] In one embodiment, as can be seen from the embodiment described above, if at least one cell set includes multiple cell sets and there are intersecting cells between the multiple cell sets, the same reference cell can be determined when determining a reference cell for each first cell set among the multiple cell sets. Downlink control information for scheduling multiple cells with this same reference cell needs to determine the occupied blind check resources when scheduling cells in each first cell set that intersects with the same reference cell. This is advantageous in simplifying the configuration logic, but it places a heavy decision burden on the same reference cell.

[0083] Therefore, considering the cell determination burden angle, in this embodiment, if at least one cell set includes multiple cell sets and intersecting cells exist between the multiple cell sets, different reference cells can be determined in each first cell set, thus avoiding an excessive determination burden on any given reference cell.

[0084] For example, for a set of multiple cells: First, we can define a sorting method (which can be called priority) for the cell set. For example, we can sort the cell set in ascending order of its identifier (id), or in descending order of its identifier, or in descending order of the blind check resources occupied by one or more DCIs set in the cell set, or in ascending order of the blind check resources occupied by one or more DCIs set in the cell set. The following explanation will mainly use sorting the cell set in ascending order of its identifier as an example.

[0085] Next, for the sorted set n (where the identifier is n), the cells included in set n are determined, and the reference cell corresponding to set m (which may be one or more cells) where all identifiers are less than n is determined. If the MC DCI schedules multiple cells in set m using the reference cell, the blind check resource occupied by the downlink control information for scheduling the multiple cells can be determined.

[0086] Next, a second cell set corresponding to cell set n is determined, and if a reference cell in set m belongs to cell set n, the second cell set is re-determined, and if the second cell set does not include the reference cell, that is, the second cell set is equal to the cell range after excluding the reference cell of set n to which all cells included in set n belong (which can be determined to be a reference cell in set m).

[0087] Finally, a reference cell is determined in the cells included in the second cell set (see the previously described embodiment), and the determined reference cell is used to determine the blind check resource occupied by the downlink control information for scheduling multiple cells when the downlink control information for scheduling multiple cells schedules multiple cells in set n.

[0090] This allows us to determine the reference cells in each of the three first cell sets mentioned above, and also ensure that the reference cells in each first cell set are different.

[0091] The following describes, through several embodiments, a method for determining at least one set of cells corresponding to downlink control information for scheduling multiple cells.

[0092] In one embodiment, the step of determining at least one set of cells corresponding to downlink control information for scheduling the plurality of cells is: A step of determining setting parameters for each cell in the plurality of cells (for example, cells on which downlink control information for scheduling the plurality of cells can be scheduled), wherein the setting parameters include, but are not limited to, a set identifier, a cell identifier, a number, and a Carrier Indicator Field (CIF), The process includes the step of determining that cells having the same configuration parameters belong to a single cell set corresponding to downlink control information for scheduling multiple cells.

[0093] For example, let's say there are four cells, Cell#1, Cell#2, Cell#3, and Cell#4, and the setting parameters include CIF. We can determine the CIF set for each of these four cells (for example, based on radio resource control RRC signaling). For example, if the CIF set for Cell#1 is 01, the CIF set for Cell#2 is 01, the CIF set for Cell#3 is 02, and the CIF set for Cell#4 is 02, we can determine that Cell#1 and Cell#2 have the same CIF, and Cell#3 and Cell#4 have the same CIF. We can then divide Cell#1 and Cell#2 into a cell set {Cell#1, Cell#2} corresponding to downlink control information for scheduling one set of multiple cells, and divide Cell#3 and Cell#4 into a cell set {Cell#3, Cell#4} corresponding to downlink control information for scheduling another set of multiple cells.

[0094] In one embodiment, the step of determining at least one set of cells corresponding to downlink control information for scheduling the plurality of cells is: The process includes: receiving instruction information transmitted by a network device in a first cell; determining a plurality of cell groups based on the instruction information received in the plurality of first cells; determining a target cell group to which the first cell belongs from among the plurality of cell groups, a set of cell groups belonging to the target cell group, and determining a set of cells corresponding to the set of cell groups.

[0095] A terminal can receive instruction information transmitted by a network device in multiple first cells, where the instruction information may indicate an association between the value of the carrier instruction field CIF corresponding to the first cell where the instruction information is received and the scheduling cell identifier, and the terminal can determine multiple cell groups based on the association corresponding to each first cell. Here, the association may specifically be an association between the value of the in-scheduling cell carrier instruction field (cif-InScheduingCell) and the scheduling cell identifier.

[0096] The terminal can determine whether the first cell is the cell to be scheduled based on the downlink control information received by the second cell for scheduling multiple cells, using the following method: The information element (IE) in the RRC message, the ServingCellConfig, is determined first. Then, the CrossCarrierSchedulingConfig in the ServingCellConfig is determined. Next, the schedulingCellInfo is determined in the CrossCarrierSchedulingConfig. If the schedulingCellInfo instruction value is "other", the schedulingCellId and cif-InSchedulingCell in schedulingCellInfo are determined.

[0097] When the scheduling cell identifier set in the RRC message is the same as the identifier of the second cell, and the cif-InScheduingCell value set in the RRC message is the same as the CIF value in the downlink control information for scheduling multiple cells received in the second cell, it can be determined that the downlink control information for scheduling multiple cells received in the second cell is used to schedule the first cell.

[0098] The aforementioned association can define a correspondence between the values ​​of multiple carrier instruction fields and multiple scheduling cell identifiers, and is not limited to the value of one carrier instruction field being associated with one scheduling cell identifier. Therefore, when a network device transmits downlink control information for scheduling multiple cells to a terminal based on the association, the downlink control information for scheduling multiple cells is advantageous in improving the scheduling flexibility for a first cell. For example, a network device can dynamically adjust the multiple cells (cell groups) to be scheduled by setting a CIF value in the transmitted downlink control information for scheduling multiple cells based on the association corresponding to the first cell to be scheduled as needed.

[0099] Figure 7 is a schematic diagram of another application scene according to an embodiment of this disclosure.

[0100] As shown in Figure 7, using Cell#0 (cell identifier 0), Cell#1 (cell identifier 1), and Cell#2 (cell identifier 2) as examples, the network device carries instruction information via RRC messages.

[0101] The relationships carried in an RRC message sent to a terminal via Cell#0 are shown in table1-0, the relationships carried in an RRC message sent to a terminal via Cell#1 are shown in table1-1, and the relationships carried in an RRC message sent to a terminal via Cell#2 are shown in table1-2.

[0102] The relationship shown in table1-0 is that the scheduling cell identifier corresponding to a value of 0 in the carrier instruction field is 2. The relationships included in Table 1-1 are such that if the scheduling cell identifier 0 corresponds to a value of 1 in the carrier instruction field, and the scheduling cell identifier 0 corresponds to a value of 2 in the carrier instruction field, then the network device can schedule the first cell (e.g., Cell #1) if the value of CIF in the downlink control information for scheduling multiple cells sent to the terminal by the second cell whose cell identifier is 0 is 1, and can also schedule the first cell (e.g., Cell #1) if the value of CIF in the downlink control information for scheduling multiple cells sent to the terminal by the second cell whose cell identifier is 0 is 2. Here, the range of the CIF value may be 0 to 7, and of course, it can be adjusted as needed.

[0103] The relationships included in Table 1-2 are that scheduling cell identifier 0 corresponds to a carrier instruction field value of 1, and scheduling cell identifier 0 corresponds to a carrier instruction field value of 3. Then, if the value of CIF in the downlink control information for scheduling multiple cells sent to the terminal by a second cell whose network device cell identifier is 0 is 1, it is possible to schedule the first cell (e.g., Cell #2). Similarly, if the value of CIF in the downlink control information for scheduling multiple cells sent to the terminal by a second cell whose cell identifier is 2 is 3, it is also possible to schedule the first cell (e.g., Cell #2).

[0104] Here, since table1-0 is the association received by scheduling cell Cell#0, the downlink control information for scheduling multiple cells received by the scheduling cell can be used for self-scheduling, that is, the downlink control information for scheduling multiple cells received by Cell#0 can be used by scheduling Cell#0 itself. Therefore, the association corresponding to Cell#0 may also include, in addition to the associations included in table1-0, that the scheduling cell identifier corresponding to a value of 0 in the carrier indicator field is 0, the scheduling cell identifier corresponding to a value of 1 in the carrier indicator field is 0, the scheduling cell identifier corresponding to a value of 2 in the carrier indicator field is 0, and the scheduling cell identifier corresponding to a value of 3 in the carrier indicator field is 0.

[0105] Note that the blank spaces in the table shown in Figure 6 can also be used to set the values ​​of the carrier instruction field and the scheduling cell identifier, but these are not shown because they are not used in the exemplary process of this embodiment. Also, the number of rows in the table is not limited to the four rows shown in the figure, and the number of rows can be reduced or increased as needed.

[0106] Based on the above-described relationships, the following can be determined: if the value of the carrier instruction field is 0 (00), the downlink control information for scheduling multiple cells can schedule Cell #0; if the value of the carrier instruction field is 1 (01), the downlink control information for scheduling multiple cells can schedule Cell #0, Cell #1, and Cell #2; if the value of the carrier instruction field is 2 (10), the downlink control information for scheduling multiple cells can schedule Cell #0 and Cell #1; and if the value of the carrier instruction field is 3 (11), the downlink control information for scheduling multiple cells can schedule Cell #0 and Cell #2. As a result, the relationship between the determined carrier instruction field value and the scheduling cell will be as shown in Table 1: [Table 1] Table 1 Here, a cell group is a cell group in which each cell corresponds to the value of each carrier instruction field (which can also be indicated by the values ​​of other fields) in the set of association relationships indicated by the instruction information received in each first cell. As shown in Table 1, multiple cell groups are {0}, {0, 1, 2}, {0, 1}, and {0, 2}. For convenience, the set contains only cell identifiers.

[0107] Each element of the tables shown in all embodiments of this disclosure exists independently, and although these elements are listed in the same table exemplarily, it should be understood that this does not mean that all elements in the table must necessarily exist simultaneously according to what is shown in the table. The value of each element is independent of the values ​​of other elements in the table. Therefore, those skilled in the art will understand that the values ​​of each element in the table are independent embodiments.

[0108] Since a cell group also has a set of cell groups to which it belongs, a set of cell groups can correspond to a set of cells. Therefore, after determining multiple cell groups, the terminal can further determine the target cell groups to which the first cell belongs. By further determining the set of cell groups to which the target cell groups belong, and the set of cells corresponding to the set of cell groups, the terminal can determine the set of cells to which the first cell belongs, i.e., the set of cells corresponding to the downlink control information for scheduling multiple cells.

[0109] Here, the cells included in different sets of cell groups are different. For example, if set of cell groups #1 includes cell group #1 and cell group #2, and set of cell groups #2 includes cell group #3 and cell group #4, then the cells included in cell group #1 and cell group #2 are different from the cells included in cell group #3 and cell group #4.

[0110] In one embodiment, the step of determining a set of cells corresponding to the set of cell groups includes the step of determining at least one set of cell groups based on the plurality of cell groups, wherein the first cell group in the first set of cell groups is the same cell that is included in at least the second cell group in the first set of cell groups, and the step of determining that the cells included in the cell group in one of the at least one set of cell groups constitute a set of cells.

[0111] After determining multiple cell groups, the terminal can determine a set of cell groups based on these multiple cell groups. Here, cell groups containing the same cell can be divided into the same set of cell groups. For example, if the first cell group and the second cell group contain the same cell, the first cell group and the second cell group can be divided into the same set of cell groups, for example, into the first set of cell groups.

[0112] Next, we can determine which cell groups contain the same cells in any of the first set of cell groups within other cell groups, and then divide these determined cell groups into the first set of cell groups. By analogy, we can complete the determination of the first set of cell groups. Furthermore, we can determine other sets of cell groups based on the method used to determine the first set of cell groups.

[0113] Note that the first and second cell groups within the same set of cell groups are different; the first and second cell groups do not refer to specific cells, but rather to any single cell group within a set of cell groups.

[0114] For example, let's determine a set of cell groups using the following cell groups as examples: {0, 1, 2, 3}, {3}, {5, 6, 7}, {3, 4, 5, 6}, {8, 9}, {8}; First, we can consider any cell group within it. For example, if we first consider cell group {0, 1, 2, 3} and determine that cell group {3} and cell group {3, 4, 5, 6} and cell group {0, 1, 2, 3} all contain the same cell #3, then we divide these three cell groups {3}, {3, 4, 5, 6}, and {0, 1, 2, 3} into a single set of cell groups, which we call, for example, the first set of cell groups.

[0115] Furthermore, in other cell groups, any cell group in the first set of cell groups can be re-evaluated to determine which cell groups contain the same cells, and it can be determined that cell group {5, 6, 7} and cell group {3, 4, 5, 6} in the first set of cell groups contain the same cells Cell #5 and Cell #6, and cell group {5, 6, 7} can also be divided into the first set of cell groups.

[0116] Since cell groups {8, 9} and {8} do not contain any of the same cells as any of the cell groups in the first set of cell groups, the determination of the first set of cell groups is complete, and the second set of cell groups can be determined next. For example, following the method described above, it can be determined that the second set of cell groups contains cell groups {8, 9} and {8}.

[0117] For example, the instruction information received in Cell#1, Cell#2, Cell#3, and Cell#4 includes the fact that the cell set identifier is 1, and the instruction information received in Cell#5, Cell#6, Cell#7, and Cell#8 includes the fact that the cell set identifier is 2. The terminal determines that Cell#1, Cell#2, Cell#3, and Cell#4 are the cell set to which identifier 1 belongs (cell set id=1), and Cell#5, Cell#6, Cell#7, and Cell#8 are the cell set to which identifier 2 belongs (cell set id=2).

[0118] Subsequently, downlink control information for scheduling multiple cells received by the terminal in the scheduling cell is downlink control information for scheduling multiple cells Cell#1, Cell#2, Cell#3, Cell#4, which can also be used to schedule multiple cells Cell#2, Cell#3, and downlink control information for scheduling other multiple cells received in the scheduling cell can be used to schedule multiple cells Cell#5, Cell#6, Cell#7, Cell#8, which can also be used to schedule multiple cells Cell#6, Cell#7. Four cell groups {1, 2, 3, 4}, {2, 3}, {5, 6, 7, 8}, {6, 7} and two cell group sets {{1, 2, 3, 4}, {2, 3}}, {{5, 6, 7, 8}, {6, 7}} can be determined. Here, different cell group sets may be the determination of the cells to be scheduled by downlink control information for scheduling multiple cells transmitted by different cells.

[0119] In one embodiment, the method for determining a cell set corresponding to a cell group set involves determining the cells included in the cell group in the cell group set, and further, the set composed of the determined cells can be considered as the cell set corresponding to the cell group set.

[0120] Figure 8 is a schematic diagram of another application scene according to an embodiment of the present disclosure.

[0121] As shown in Figure 8, the first and second cell group sets determined in the above-described embodiment are used as examples, where the first cell group set is {{0, 1, 2, 3}, {3}, {3, 4, 5, 6}, {5, 6, 7}} and the second cell group set is {{8, 9}, {8}}.

[0122] If it can be determined that the cells included in the first set of cell groups are Cell#0, Cell#1, Cell#2, Cell#3, Cell#4, Cell#5, Cell#6, and Cell#7, then it can be determined that the set of cells composed of these cells is {0, 1, 2, 3, 4, 5, 6, 7}, that is, the set of cells corresponding to the first set of cell groups is {0, 1, 2, 3, 4, 5, 6, 7}, and similarly, it can be determined that the set of cells corresponding to the second set of cell groups is {8, 9}. At least one set of cells corresponding to downlink control information for scheduling multiple cells includes the set of cells {0, 1, 2, 3, 4, 5, 6, 7} and the set of cells {8, 9}.

[0123] In one embodiment, the step of determining at least one set of cells corresponding to downlink control information for scheduling the plurality of cells includes the steps of receiving instruction information transmitted by a network device in a first cell, determining a plurality of cell groups based on the instruction information received in the plurality of first cells, and determining that the cell group is in a set of cells.

[0124] Here, the method for determining multiple cell groups is similar to that of the previously described embodiment and will not be described further here. The difference between this embodiment and the previously described embodiment is that, instead of determining the cell sets belonging to the cell groups, the cell groups are directly determined as cell sets. For example, after determining table 1 based on instruction information, each of the multiple cell groups {0}, {0, 1, 2}, {0, 1}, and {0, 2} within table 1 can be treated as a cell set. That is, at least one cell set corresponding to the downlink control information for scheduling multiple cells includes these four sets: {0}, {0, 1, 2}, {0, 1}, and {0, 2}.

[0125] Figure 9 is a flowchart of a cell determination method according to an embodiment of the present disclosure. The cell determination method shown in this embodiment can be performed by a network device, which can communicate with a terminal, and the network device includes, but is not limited to, base stations in a communication system such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.

[0126] As shown in Figure 9, the cell determination method may include the following steps: In step S901, at least one set of cells corresponding to downlink control information for scheduling multiple cells is determined. In step S902, for each first cell set among the at least one cell set, a reference cell in the first cell set is determined, and the downlink control information for scheduling the plurality of cells is determined to be the blind check resource that is occupied when scheduling the cells in the first cell set.

[0127] In one embodiment, if the at least one cell set includes multiple cell sets, the multiple cell sets may or may not contain the same cell.

[0128] In one embodiment, downlink control information for scheduling multiple cells can be abbreviated as, for example, MC-DCI, which is used to schedule multiple cells and specifically refers to data for scheduling multiple cells, such as PUSCH, PDSCH, etc., for scheduling one or more cells among multiple cells, thereby realizing the scheduling of multiple cells via a single DCI. Here, MC stands for Multi-cell.

[0129] In one embodiment, the format of the downlink control information for scheduling multiple cells may be the same as the legacy DCI format (e.g., DCI format 0_0, DCI format 0_1, etc.), or a newly defined format, such as DCI format 0_3, DCI format 1_3, etc., may be used.

[0130] In one embodiment, downlink control information for scheduling multiple cells can be scrambled with a Radio Network Temporary Identity (RNTI), for example, with a cell radio network temporary identifier C-RNTI, or with a newly defined RNTI.

[0131] Downlink control information for scheduling multiple cells can be used to schedule multiple cells, and compared to DCI for scheduling a single cell in legacy DCI, the amount of information in the downlink control information for scheduling multiple cells is relatively larger, and consequently, the amount of blind check resources occupied is also relatively larger. A terminal can receive downlink control information for scheduling multiple cells (scheduled cells) used to schedule multiple cells in a scheduling cell, but if all occupied blind check resources are determined based on the scheduling cell, it becomes too burdensome for the scheduling cell and is detrimental to ensuring good blind check efficiency and blind check performance.

[0132] According to embodiments of the present disclosure, after a network device determines at least one set of cells corresponding to downlink control information for scheduling multiple cells, it can determine a reference cell in the first set of cells for each of the first sets of cells, and further, when the downlink control information for scheduling multiple cells subsequently schedules a cell in the first set of cells, it can determine the blind check resource occupied by the downlink control information for scheduling multiple cells at the reference cell in the first set of cells.

[0133] For example, if at least one cell set includes a first cell set set#1, a first cell set set#2, etc., it is possible to determine the reference cell Cell#1 in set#1 and the reference cell Cell#2 in set#2. Furthermore, if downlink control information for scheduling multiple cells is subsequently received, and it is determined that the downlink control information for scheduling multiple cells will be used to schedule multiple cells in set#1, it is possible to determine the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#1. If it is determined that the downlink control information for scheduling multiple cells will be used to schedule multiple cells in set#2, it is possible to determine the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#2.

[0134] Downlink control information for scheduling multiple cells can schedule multiple cells, for example, it can schedule multiple cells in a first cell set. In this embodiment, the reference cell in the first cell set can be determined, and the downlink control information for scheduling multiple cells in the reference cell determines the blind check resources occupied when scheduling cells in the first cell set, which is advantageous for subsequent terminals to ensure blind check efficiency and blind check performance for the downlink control information.

[0135] After the terminal determines a reference cell in the first cell set, the downlink control information for scheduling the multiple cells can determine the blind check resources to be occupied when scheduling the cells in the first cell set. If the determined blind check resources exceed the blind check capacity, some of the blind check resources corresponding to the configured DCI can be dropped, and the blind check of the DCI is not performed with these dropped blind check resources.

[0136] On the other hand, the network device determines a reference cell in a first cell set, and the downlink control information for scheduling the multiple cells in the reference cell in the first cell set determines the blind check resources occupied when scheduling the cells in the first cell set. This is advantageous because it allows for the determination of blind check resources that can be subsequently discarded by terminals, thereby improving the flexibility and effectiveness of scheduling.

[0137] Here, after determining the reference cell, the network device can determine the settings for the search space SS and / or the control resource set CORESET corresponding to the downlink control information for scheduling multiple cells set in the reference cell. Furthermore, based on the settings for SS and / or CORESET, it can determine the blind check resources occupied by the downlink control information for scheduling multiple cells. For example, the blind check determines the time-domain field resources and frequency-domain field resources of the downlink control information for scheduling multiple cells. Then, the blind check calculates the blind check resources occupied by all DCIs (e.g., downlink control information for scheduling multiple cells and legacy DCIs) that include the downlink control information for scheduling multiple cells in a slot or time span of the downlink control information for scheduling multiple cells.

[0138] Note that the reference cell in the first set of cells may be a single cell or multiple cells; these two cases will be explained later with examples.

[0139] In one embodiment, the blind check resource is Candidate physical downlink control channels (PDCCH candidates) and... It includes at least one of the control channel elements (CCEs).

[0140] Here, determining the blind check resources means determining the number of blind check resources. For example, for the two types of blind check resources mentioned above, this means determining the number of blind check resources, at least one of the PDCCH candidates or CCEs, that occupy a certain time domain field range, for example, within one slot range or one PDCCH span range. Note that the blind check resources determined by this disclosure are not limited to the PDCCH candidates or CCEs mentioned above, and other blind check resources may be determined as needed. For example, the determined blind check resources may further include blind check BDs, where BD refers to the number of PDCCH candidates that occupy a certain length of time.

[0141] The following describes, by some embodiment, a method for determining a reference cell in the first cell set. Here, the method for determining a reference cell in the first cell set can be determined based on predefined rules (e.g., protocol agreements), or based on instructions from a network device, and the disclosure is not limited thereto.

[0142] In one embodiment, the step of determining a reference cell in the first set of cells includes the step of determining a reference cell in the first set of cells based on a cell identifier.

[0143] In one embodiment, when determining a reference cell in a first set of cells, first, the cell identifier (Cell ID) of each cell in the first set of cells is determined, and then, based on the cell identifier of each cell, a reference cell can be selected in the set of cells included in the first set of cells.

[0144] In one embodiment, the step of determining a reference cell in the first cell set based on the cell identifier includes, if the reference cell in the first cell set includes one cell, determining the cell with the largest cell identifier or the cell with the smallest cell identifier in the first cell set as the reference cell, or, if the reference cell in the first cell set includes multiple cells, determining multiple cells in the first cell set in descending order of identifiers as the reference cells in the first cell set, or determining multiple cells in the first cell set in ascending order of cell identifiers as the reference cells in the first cell set.

[0145] In one embodiment, if the reference cell in the first cell set contains one cell, determining the reference cell in the first cell set based on the cell identifier can be done by determining the cell with the largest cell identifier as the reference cell in the first cell set, or by determining the cell with the smallest cell identifier as the reference cell in the first cell set.

[0146] For example, the first set of cells includes cells Cell#1 (Cell ID is 1), Cell#2 (Cell ID is 2), Cell#3 (Cell ID is 3), and Cell#4 (Cell ID is 4). When the cell with the largest cell identifier is determined as the reference cell in the first set of cells, Cell#4 can be determined as the reference cell in the first set of cells. When the cell with the smallest cell identifier is determined as the reference cell in the first set of cells, Cell#1 can be determined as the reference cell in the first set of cells.

[0147] In one embodiment, if a reference cell in the first cell set includes multiple cells, determining the reference cell in the first cell set based on the cell identifier can be done by determining multiple cells in the first cell set in descending order of identifier as the reference cell in the first cell set, or by determining multiple cells in the first cell set in ascending order of cell identifier as the reference cell in the first cell set.

[0148] For example, the first set of cells contains Cell#1 (Cell ID is 1), Cell#2 (Cell ID is 2), Cell#3 (Cell ID is 3), and Cell#4 (Cell ID is 4), and has 2 reference cells. When the cell with the largest cell identifier is determined as the reference cell in the first set of cells, Cell#4 and Cell#3 can be determined as reference cells in the first set of cells. When the cell with the smallest cell identifier is determined as the reference cell in the first set of cells, Cell#1 and Cell#2 can be determined as reference cells in the first set of cells.

[0149] In one embodiment, cells in a first set of cells can be sorted in a first order (for example, determined based on a predefined rule or based on a network instruction), and then a reference cell in the first set of cells can be determined based on the sort number of the cells. For example, the first order may include, but is not limited to, the order of cell identifiers in ascending order or in ascending order.

[0150] Let's take the example of a first cell set containing four cells: Cell#1, Cell#2, Cell#3, and Cell#4. For instance, the first sorting order is performed by sorting the cells in descending order according to their Cell IDs, resulting in Cell#4, Cell#3, Cell#2, and Cell#1. For example, if we determine that the cell with sort number 3 is the reference cell of the first cell set, and we know that Cell#2 is the cell with sort number 3, we can then determine that Cell#2 is the reference cell of the first cell set.

[0151] In one embodiment, the step of determining a reference cell in the first cell set includes determining a reference cell in the first cell set based on the blind check resources occupied by the DCI set for each cell in the first cell set.

[0152] In one embodiment, when determining a reference cell in a first cell set, DCI can first determine the blind check resources occupied by each cell in the first cell set, and then determine the reference cell in the first cell set based on the blind check resources occupied by DCI in each cell in the first cell set.

[0153] In one embodiment, the step of determining a reference cell in the first cell set based on the blind check resources occupied by the DCI set for each cell in the first cell set includes, if the reference cell in the first cell set includes one cell, determining the cell with the fewest blind check resources occupied by the DCI in the first cell set as the reference cell in the first cell set, or, if the reference cell in the first cell set includes multiple cells, determining multiple cells in the first cell set as reference cells in order of increasing blind check resources occupied by the DCI (which is the DCI set for each cell in the first cell set).

[0154] Here, the blind check resources occupied by the DCI configured for each cell may be the blind check resources occupied by the legacy DCI configured for each cell, or they may be the blind check resources occupied by all DCI configured for each cell (for example, including legacy DCIs and downlink control information for scheduling multiple cells).

[0155] In one embodiment, taking the legacy DCI set for each cell as an example, if the legacy DCI set for a cell occupies a large number of blind check resources, then under certain conditions, the number of blind check resources occupied by the downlink control information for scheduling multiple cells will be small, corresponding to the DCI set for the cell. Therefore, if the reference cell in the first cell set contains one cell, it is possible to first determine the number of blind check resources occupied by the legacy DCI set for each cell in the first cell set, and then determine that the cell with the fewest blind check resources occupied by the legacy DCI is the reference cell in the first cell set. This is advantageous in ensuring the blind check capability of the downlink control information for scheduling multiple cells in the reference cell of the terminal.

[0156] In one embodiment, taking the blind check resources occupied by all DCIs set for each cell as an example, the fewer the blind check resources occupied by all DCIs set for a cell, the lower the complexity of the terminal's blind check. Therefore, if the reference cell in the first cell set contains one cell, first, the blind check resources occupied by all DCIs set for each cell in the first cell set can be determined, and then the cell with the fewest blind check resources occupied by all DCIs can be determined as the reference cell in the first cell set. This is advantageous in reducing the complexity of the terminal's blind check on the reference cell.

[0157] For example, the first set of cells includes cells Cell#1, Cell#2, Cell#3, and Cell#4. For these four cells, the blind check resources occupied by the DCI set for each cell can be determined to be, for example, R1 for the DCI set for Cell#1, R2 for the DCI set for Cell#2, R3 for the DCI set for Cell#3, and R4 for the DCI set for Cell#4. The order of these four blind check resources from smallest to largest is R2, R3, R4, and R1. In other words, the DCI set for Cell#2 has the smallest blind check resource R2, so Cell#2 can be selected as the reference cell. Downlink control information for scheduling multiple cells is used to determine which blind check resources are occupied.

[0158] In embodiments of this disclosure, determining the blind check resources occupied by the DCI set up for a given cell includes, but is not limited to, the following two methods: Method 1: Determine the search space set for the cell, and sum all blind-checked resources of DCI in the search space (e.g., PDCCH candidates). Method 2: Determine the search space set up for the cell and sum the blind check resources of the corresponding DCI within a specific time unit in the search space. Here, the specific time unit may be defined by a predefined rule or indicated by a network device, and may be one or more frames and / or one or more subframes and / or one or more slots and / or one or more symbols and / or one or more PDCCH spans.

[0159] In one embodiment, taking the legacy DCI set for each cell as an example, the legacy DCI set for a cell occupies a large number of blind check resources, so the downlink control information for scheduling multiple cells occupies fewer blind check resources. Therefore, if the reference cell in the first cell set includes multiple cells, first, the blind check resources occupied by the legacy DCI set for each cell in the first cell set can be determined, and then multiple cells in the first cell set can be determined as reference cells in the first cell set in ascending order of the blind check resources occupied by the legacy DCI. This is advantageous in ensuring the blind check capability of the downlink control information for scheduling multiple cells in the terminal's reference cell.

[0160] In one embodiment, taking the blind check resources occupied by all DCIs set for each cell as an example, the fewer the blind check resources occupied by all DCIs set for a cell, the relatively lower the complexity of the terminal's blind check. Therefore, if the reference cell in the first cell set includes multiple cells, first, the blind check resources occupied by all DCIs set for each cell in the first cell set can be determined, and then multiple cells in the first cell set can be determined as reference cells in the first cell set in ascending order of the blind check resources occupied by all DCIs. This is advantageous in ensuring the ability to blind check downlink control information for scheduling multiple cells in the terminal's reference cell.

[0161] For example, the number of reference cells is 2, and the first cell set includes cells Cell#1, Cell#2, Cell#3, and Cell#4. For these four cells, it can be determined that the blind check resources occupied by the DCI set for each cell are, for example, R1 for the DCI set for Cell#1, R2 for the DCI set for Cell#2, R3 for the DCI set for Cell#3, and R4 for the DCI set for Cell#4. The order of these four blind check resources from smallest to largest is R2, R3, R4, and R1. That is, the blind check resource R2 occupied by the DCI set for Cell#2 is the smallest, followed by the blind check resource R3 occupied by the DCI set for Cell#3. Next, Cell#2 and Cell#3 can be selected as reference cells, and downlink control information for scheduling multiple cells is used to determine the blind check resources occupied. Determining the blind check resources occupied by the DCI set in the aforementioned cell has already been explained above and will not be explained further here.

[0162] In one embodiment, the DCI includes at least one of a conventional DCI and all the DCIs set in the cell.

[0163] In one embodiment, the step of determining a reference cell in the first cell set includes determining a cell in the first cell set as a reference cell for determining the size budget of downlink control information for scheduling the plurality of cells in the first cell set.

[0164] In one embodiment, when downlink control information for scheduling multiple cells schedules multiple cells in a first set of cells, at least one cell in the multiple cells can determine the size (i.e., the number of bits occupied) budget of the downlink control information for scheduling the multiple cells, and at least one cell specifically aligns the size of the DCI (DCI containing the downlink control information for scheduling the multiple cells).

[0165] When selecting a reference cell, at least one cell can be selected as the reference cell to determine the size budget of the downlink control information for scheduling the multiple cells. In the process of scheduling the multiple cells using downlink control information for scheduling multiple cells, the decision actions performed by the cells that need to be scheduled can be concentrated on a single cell, which is advantageous for simplifying the setting logic for the cells.

[0166] In one embodiment, a cell in the first cell set that has a search space set corresponding to downlink control information for scheduling the plurality of cells is determined to be a reference cell in the first cell set.

[0167] In one embodiment, when determining a reference cell in a first cell set, first, a search space corresponding to downlink control information for scheduling multiple cells that schedule cells in the first cell set can be determined, and then a cell in the first cell set that has a search space corresponding to the downlink control information for scheduling the multiple cells set up can be determined as the reference cell. For example, if the search space is SS#1, that is, an SS with identifier 1, then a cell (which may be one or more cells) in the first cell set that has an SS identified as 1 can be determined as the reference cell.

[0168] Furthermore, the embodiments for determining the reference cell in several of the first cell sets described above can be implemented individually and combined as needed. For example, it is possible to determine a cell in the first cell set that has a search space set up corresponding to downlink control information for scheduling multiple cells. If multiple cells have been determined, it is possible to further determine the cell with the fewest blind check resources occupied by the DCI set up in each of the multiple cells as the reference cell.

[0169] In one embodiment, if the reference cell in the first cell set includes multiple cells, the step of determining the blind check resources occupied by the downlink control information for scheduling the multiple cells in the first cell set when scheduling the cells in the first cell set in the reference cell includes determining the blind check resources occupied by the downlink control information for scheduling the multiple cells set in each of the reference cells in the first cell set.

[0170] In one embodiment, if a reference cell includes multiple cells, each of these cells can determine the blind check resources occupied by the downlink control information for scheduling the multiple cells.

[0171] Let's take the example where the first set of cells includes Cell#1, Cell#2, Cell#3, and Cell#4.

[0172] If the determined reference cells are Cell#1 and Cell#2, it is possible to determine the blind check resources occupied by downlink control information for scheduling multiple cells in Cell#1, and it is also possible to determine the blind check resources occupied by downlink control information for scheduling multiple cells in Cell#2.

[0173] If all cells in the first cell set are determined to be reference cells, then the blind check resources occupied by downlink control information for scheduling multiple cells can be determined in Cell#1, the blind check resources occupied by downlink control information for scheduling multiple cells can be determined in Cell#2, the blind check resources occupied by downlink control information for scheduling multiple cells can be determined in Cell#3, and the blind check resources occupied by downlink control information for scheduling multiple cells can be determined in Cell#4.

[0174] In one embodiment, the step of determining the blind check resources occupied by downlink control information for scheduling a plurality of cells set in each of the reference cells in the first cell set includes the step of determining the blind check resources based on the determination result and quantization coefficients in each of the cells.

[0175] When determining the blind check resources occupied by downlink control information for scheduling multiple cells set in each of the reference cells in the first cell set, the determination result for each cell (i.e., the determined blind check resource) can be processed by a quantization coefficient (for example, by performing algorithmic processing such as multiplying, dividing, adding, subtracting, squaring, or taking the logarithm of the determination result based on the quantization coefficient) to obtain the final blind check resource. For example, the determination result for a certain cell can be multiplied by a quantization coefficient to obtain the final determined blind check resource for that cell.

[0176] In one embodiment, the quantization coefficient is determined based on the number of cells (e.g., all or some cells in a first cell set) contained in the reference cell, for example, the quantization coefficient may be 1 / K of the number of cells contained in the reference cell, where K is the number of cells contained in the reference cell. This is advantageous in reducing the overall burden of determining the blind check resources occupied by downlink control information for scheduling multiple cells in multiple cells.

[0177] Let's take the example where the first set of cells includes Cell#1, Cell#2, Cell#3, and Cell#4.

[0178] If the determined reference cells are Cell#1 and Cell#2, the quantization coefficient is 1 / 2. Decision result A, which determines the blind check resource occupied by the downlink control information for scheduling multiple cells in Cell#1, can be multiplied by 1 / 2 to obtain A / 2, which can be used as the blind check resource occupied by the downlink control information for scheduling multiple cells determined in Cell#1. Decision result B, which determines the blind check resource occupied by the downlink control information for scheduling multiple cells in Cell#2, can be multiplied by 1 / 2 to obtain B / 2, which can be used as the blind check resource occupied by the downlink control information for scheduling multiple cells determined in Cell#1.

[0179] If the determined reference cells are Cell#1, Cell#2, Cell#3, and Cell#4, the quantization coefficient is 1 / 4. Decision result A, which determines the blind check resource occupied by downlink control information for scheduling multiple cells in Cell#1, can be multiplied by 1 / 4 to obtain A / 4, which can be used as the blind check resource occupied by downlink control information for scheduling multiple cells determined in Cell#1. Decision result B, which determines the blind check resource occupied by downlink control information for scheduling multiple cells in Cell#2, can be multiplied by 1 / 4 to obtain B / 4, which can be used as the blind check resource occupied by downlink control information for scheduling multiple cells determined in Cell#1. Decision result C, which determines the blind check resource occupied by downlink control information for scheduling multiple cells in Cell#3, can be multiplied by 1 / 4 to obtain C / 4, which can be used as the blind check resource occupied by downlink control information for scheduling multiple cells determined in Cell#3. Decision result D, which determines the blind check resource occupied by downlink control information for scheduling multiple cells in Cell#4, can be multiplied by 1 / 4 to obtain D / 4, which can be used as the blind check resource occupied by downlink control information for scheduling multiple cells determined in Cell#4.

[0180] In one embodiment, if the at least one cell set includes multiple cell sets and there are intersecting cells between the multiple cell sets, and if the multiple first cell sets include the same reference cell, then downlink control information for scheduling the multiple cells with the same reference cell determines the blind check resources to be occupied when scheduling cells in each of the multiple first cell sets.

[0181] In one embodiment, if at least one cell set is present in multiple cell sets, then the multiple cell sets may have intersecting cells (containing the same cell) and may not have intersecting cells (not containing the same cell).

[0182] For example, let's consider two sets of cells.

[0183] If cell set #1 is {Cell #1, Cell #2, Cell #3} and cell set #2 is {Cell #1, Cell #4, Cell #5}, then there is an intersection {Cell #1} between set #1 and set #2, and the intersecting cell is Cell #1.

[0184] If cell set #1 is {Cell #1, Cell #2, Cell #3} and cell set #3 is {Cell #4, Cell #5, Cell #6}, then there is no intersection between set #1 and set #3.

[0185] When there are intersecting cells between multiple sets of cells, the same reference cell can be determined when determining a reference cell for each first set of cells among the multiple sets. In this case, the blind check resources occupied by the downlink control information for scheduling multiple cells can be determined when scheduling cells in each first set of cells that intersect with that same reference cell. In this case, the blind check resources occupied by the downlink control information for scheduling multiple cells determined by the same reference cell are the sum of the blind check resources occupied by the downlink control information for scheduling multiple cells determined for each first set of cells.

[0186] For example, if it is determined that the reference cell in set#1 is Cell#1, and the reference cell in set#2 is also Cell#1, and Cell#1 is the same reference cell, then the downlink control information for scheduling multiple cells in Cell#1 determines the blind check resource occupied by the downlink control information for scheduling multiple cells when scheduling multiple cells in set#1, for example, A, and the downlink control information for scheduling multiple cells in Cell#1 determines the blind check resource occupied by the downlink control information for scheduling multiple cells when scheduling multiple cells in set#2, for example, B. The blind check resource occupied by the downlink control information for scheduling multiple cells determined in Cell#1 is the sum of A and B.

[0187] In embodiments of this disclosure, determining the blind check resources occupied by downlink control information for scheduling multiple cells set for a given cell includes, but is not limited to, the following two methods: Method 1: Determine the search space set for the cell, and sum all blind check resources (e.g., PDCCH candidates) of the downlink control information for scheduling multiple cells within the search space. Method 2: Determine the search space set up for the cell and sum up the blind-check resources of downlink control information for scheduling multiple cells within a specific time unit in the search space. Here, the specific time unit may be defined by a predefined rule or indicated by a network device, and may be one or more frames and / or one or more subframes and / or one or more slots and / or one or more symbols.

[0188] In one embodiment, if the at least one cell set includes a plurality of cell sets and there are intersecting cells between the plurality of cell sets, the step of determining a reference cell in the first cell set for each first cell set of the at least one cell set includes determining a reference cell in the first cell set for each first cell set of the plurality of first cell sets, and the reference cell in each first cell set includes different steps.

[0189] In one embodiment, as can be seen from the embodiment described above, if at least one cell set includes multiple cell sets and there are intersecting cells between the multiple cell sets, the same reference cell can be determined when determining a reference cell for each first cell set among the multiple cell sets. Downlink control information for scheduling multiple cells with this same reference cell needs to determine the occupied blind check resources when scheduling cells in each first cell set that intersects with the same reference cell. This is advantageous in simplifying the configuration logic, but it places a heavy decision burden on the same reference cell.

[0190] Therefore, considering the cell determination burden angle, in this embodiment, if at least one cell set includes multiple cell sets and intersecting cells exist between the multiple cell sets, different reference cells can be determined in each first cell set, thus avoiding an excessive determination burden on any given reference cell.

[0191] For example, for a set of multiple cells: First, we can define a sorting method (which can be called priority) for the cell set. For example, we can sort the cell set in ascending order of its identifier (id), or in descending order of its identifier, or in descending order of the blind check resources occupied by one or more DCIs set in the cell set, or in ascending order of the blind check resources occupied by one or more DCIs set in the cell set. The following explanation will mainly use sorting the cell set in ascending order of its identifier as an example.

[0192] Next, for the sorted set n (where the identifier is n), the cells included in set n are determined, and the reference cell corresponding to set m (which may be one or more cells) where all identifiers are less than n is determined. If the MC DCI schedules multiple cells in set m using the reference cell, the blind check resource occupied by the downlink control information for scheduling the multiple cells can be determined.

[0193] Next, a second cell set corresponding to cell set n is determined, and if a reference cell in set m belongs to cell set n, the second cell set is re-determined, and if the second cell set does not include the reference cell, that is, the second cell set is equal to the cell range after excluding the reference cell of set n to which all cells included in set n belong (which can be determined to be a reference cell in set m).

[0194] Finally, a reference cell is determined in the cells included in the second cell set (see the previously described embodiment), and the determined reference cell is used to determine the blind check resource occupied by the downlink control information for scheduling multiple cells when the downlink control information for scheduling multiple cells schedules multiple cells in set n.

[0197] This allows us to determine the reference cells in each of the three first cell sets mentioned above, and also ensure that the reference cells in each first cell set are different.

[0198] The following describes, through several embodiments, a method for determining at least one set of cells corresponding to downlink control information for scheduling multiple cells.

[0199] In one embodiment, the step of determining at least one set of cells corresponding to downlink control information for scheduling the plurality of cells is: The steps include determining the setting parameters for each cell in multiple cells (for example, cells in which downlink control information for scheduling multiple cells can be scheduled), The process includes the step of determining that cells having the same configuration parameters belong to a single cell set corresponding to downlink control information for scheduling multiple cells.

[0200] For example, let's say we have four cells, Cell#1, Cell#2, Cell#3, and Cell#4, and their configuration parameters include a Carrier Indicator Field (CIF). We can determine the CIF set for each of these four cells (for example, based on radio resource control RRC signaling). For example, if the CIF set for Cell#1 is 01, the CIF set for Cell#2 is 01, the CIF set for Cell#3 is 02, and the CIF set for Cell#4 is 02, we can determine that Cell#1 and Cell#2 have the same CIF, and Cell#3 and Cell#4 have the same CIF. We can then divide Cell#1 and Cell#2 into a cell set {Cell#1, Cell#2} corresponding to downlink control information for scheduling one set of cells, and Cell#3 and Cell#4 into a cell set {Cell#3, Cell#4} corresponding to downlink control information for scheduling another set of cells.

[0201] In one embodiment, the step of determining at least one set of cells corresponding to downlink control information for scheduling the plurality of cells includes the step of receiving instruction information transmitted by a network device in a first cell, wherein the instruction information transmitted by the plurality of first cells is used to instruct a plurality of cell groups; the step of determining a target cell group to which the first cell belongs among the plurality of cell groups, a set of cell groups belonging to the target cell group; and the step of determining a set of cells corresponding to the set of cell groups.

[0202] In one embodiment, a network device can transmit instruction information to a terminal in a plurality of first cells, where the instruction information can indicate an association between the value of a carrier instruction field CIF corresponding to a first cell present for transmitting the instruction information and a scheduling cell identifier, and the network device can determine a plurality of cell groups based on the associations corresponding to each first cell, where the association may specifically be an association between the value of a scheduling cell carrier instruction field (cif-InScheduingCell) and a scheduling cell identifier.

[0203] Here, the function of the relationship is explained in the embodiment corresponding to the terminal side in the preceding paragraph and will not be discussed further here. The method by which a network device determines multiple cell groups is opposite to the method by which a terminal determines multiple cells. On the one hand, the network device can determine multiple cell groups before transmitting instruction information and instruct the terminal via the instruction information, while the terminal can only determine multiple cells after receiving the instruction information. The method by which a network device determines at least one set of cells corresponding to downlink control information for scheduling multiple cells also corresponds to the embodiment on the terminal side and will not be discussed here either.
