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

[0017] The terms used in the embodiments of the present disclosure are merely for the purpose of describing particular embodiments and are not intended to limit the embodiments of the present disclosure.

Furthermore, as used herein, the term "and / or" refers to any and all possible combinations of one or more of the associated listed items.

[0018] In embodiments of the present disclosure, terms such as first, second, and third may be used to describe various pieces of information, but it should be understood that such information should not be limited to these terms. These terms are merely used to distinguish between the same types of information. For example, first information could be referred to as second information, and similarly, second information could be referred to as first information, without departing from the scope of embodiments of the present disclosure. Depending on the context, the word "if" as used herein can be interpreted as "when" or "in the case of" or "responsive to a determination."

[0019] For purposes of brevity and ease of understanding, the terms used herein to characterize magnitude relationships are "greater than" or "smaller," "higher" or "lower." However, to those skilled in the art, the term "greater than" also includes the meaning of "greater than or equal to," the term "smaller" also includes the meaning of "less than or equal to," the term "higher" includes the meaning of "higher than or equal to," and the term "lower" includes the meaning of "lower or equal to."

[0020] 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, core networks, etc. in communication systems such as 4G, 5G, and 6G.

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

[0022] In one embodiment, when the at least one cell set includes a plurality of cell sets, the plurality of cell sets may include the same cell, or the plurality of cells may not include the same cell.

[0023] In one embodiment, the downlink control information for scheduling multiple cells may be abbreviated as MC-DCI, for example, where MC-DCI is used for scheduling multiple cells, and specifically refers to data for scheduling multiple cells, such as PUSCH, PDSCH, etc., for scheduling one or more cells among the multiple cells, thereby realizing scheduling of multiple cells via one DCI, where 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 format of a legacy DCI (e.g., DCI format 0_0, DCI format 0_1, etc.), or may use a newly defined format, e.g., DCI format 0_3, DCI format 1_3, etc.

[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 Identity C-RNTI, or can also be scrambled with a newly defined RNTI.

[0026] The downlink control information for scheduling multiple cells can be used to schedule multiple cells, and compared with the DCI for scheduling a single cell among legacy DCIs, the downlink control information for scheduling multiple cells contains relatively more information, and therefore the occupied blind check resources are also relatively more. Although the UE can receive downlink control information for scheduling multiple cells (scheduled cell) used for scheduling multiple cells from the scheduling cell, determining all occupied blind check resources based on the scheduling cell places too much burden on the scheduling cell, which is disadvantageous in ensuring good blind check efficiency and blind check performance.

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

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

[0029] The downlink control information for scheduling a plurality of cells can schedule a plurality of cells, for example, can schedule a plurality of cells in a first cell set. In this case, this embodiment can determine a reference cell in the first cell set, and determine blind check resources to be occupied when the downlink control information for scheduling a plurality of cells in the reference cell schedules the cells in the first cell set, or can determine the blind check resources by introducing a proportional coefficient, which is advantageous for the terminal to ensure blind check efficiency and blind check performance for the downlink control information and to ensure fairness in blind check resource allocation.

[0030] Here, after determining the reference cell, the terminal may determine a search space (SS) setting and / or a control resource set (CORESET) setting corresponding to downlink control information for scheduling multiple cells set to the reference cell, and may further determine blind check resources occupied by the downlink control information for scheduling multiple cells based on the SS setting and / or the CORESET setting. For example, the blind check determines time domain field resources and frequency domain field resources of the downlink control information for scheduling multiple cells, and then calculates blind check resources occupied by all DCI (e.g., downlink control information for scheduling multiple cells and legacy DCI) including downlink control information for scheduling multiple cells in a slot or time span of the downlink control information for scheduling multiple cells.

[0031] The reference cell in the first cell set may be one cell or multiple cells, and these two cases will be described below using examples.

[0032] In one embodiment, the blind check resource comprises: Candidate physical downlink control channel PDCCH (Physical Downlink Control Channel) candidates, and It includes at least one of the Control Channel Elements (CCE).

[0033] Here, determining blind check resources refers to determining the number of blind check resources, for example, for the above two types of blind check resources, it refers to determining the number of at least one blind check resource among PDCCH candidates and CCEs occupying a certain time domain field range, for example, within one slot range or one PDCCH span range. Note that the blind check resources determined in the present disclosure are not limited to the above PDCCH candidates and CCEs, and other blind check resources may be determined as needed. For example, the determined blind check resources may further include blind decoding (BD), where BD refers to the number of PDCCH candidates occupying a certain time length.

[0034] The following describes exemplary methods for determining a reference cell in the first cell set according to some embodiments. Here, the method for determining a reference cell in the first cell set may be determined based on a predefined rule (e.g., protocol agreement) or an instruction from a network device, but the present disclosure is not limited thereto.

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

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

[0037] In one embodiment, determining a reference cell in the first cell set based on the cell identifier comprises: If the reference cells in the first cell set include 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 in the first cell set; or When the reference cells in the first cell set include multiple cells, the method includes a step of determining multiple cells in the first cell set in descending order of identifiers as reference cells in the first cell set, or determining multiple cells in the first cell set in descending order of cell identifiers as reference cells in the first cell set.

[0038] In one embodiment, when the reference cell in the first cell set includes one cell, determining the reference cell in the first cell set based on the cell identifier may determine the cell with the largest cell identifier as the reference cell in the first cell set, or may determine the cell with the smallest cell identifier as the reference cell in the first cell set.

[0039] For example, the first cell set 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 cell set, Cell#4 can be determined as the reference cell in the first cell set, and when the cell with the smallest cell identifier is determined as the reference cell in the first cell set, Cell#1 can be determined as the reference cell in the first cell set.

[0040] In one embodiment, when the 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 determine multiple cells in the first cell set in descending order of identifiers as reference cells in the first cell set, or can determine multiple cells in the first cell set in descending order of cell identifiers as reference cells in the first cell set.

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

[0042] In one embodiment, the cells in the first cell set may be sorted in a first order (e.g., determined based on a predefined rule or a network instruction), and then a reference cell in the first cell set may be determined based on the sorting number of the cell. For example, the first order may include, but is not limited to, ascending order of cell identifiers, descending order of cell identifiers, or descending order or ascending order of blind check resources corresponding to DCIs configured in each cell. Here, a method for determining blind check resources corresponding to DCIs configured in each cell will be described later.

[0043] For example, if the first cell set includes four cells, Cell#1, Cell#2, Cell#3, and Cell#4, the first order is to sort the cells in ascending order according to the Cell ID, and the sorting result is Cell#4, Cell#3, Cell#2, and Cell#1. For example, if the cell with sort number 3 is determined as the reference cell for the first cell set, and it is known that Cell#2 is the cell with sort number 3, then Cell#2 can be determined as the reference cell for the first cell set.

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

[0045] In one embodiment, when determining a reference cell in a first cell set, first, the blind check resource that the DCI occupies for each cell in the first cell set can be determined, and then the reference cell in the first cell set can be determined based on the blind check resource that the DCI occupies for each cell in the first cell set.

[0046] In one embodiment, the step of determining a reference cell in the first cell set based on a blind check resource occupied by a DCI configured in each cell of the first cell set includes: If the reference cell in the first cell set includes one cell, determining a cell in the first cell set with the least blind check resource occupied by DCI as the reference cell in the first cell set; or When the reference cell in the first cell set includes multiple cells, the method includes a step of determining multiple cells as reference cells in the first cell set in order of the smallest blind check resources occupied by DCI (which is the DCI set for each cell in the first cell set) in the first cell set.

[0047] Here, the blind check resource occupied by the DCI configured in each cell may be the blind check resource occupied by the legacy DCI configured in each cell, or may be the blind check resource occupied by all DCI configured in each cell (e.g., including the legacy DCI and downlink control information for scheduling multiple cells).

[0048] In one embodiment, taking the blind check resources occupied by the legacy DCI configured in each cell as an example, if the blind check resources occupied by the legacy DCI configured for a cell are large, under certain conditions, the blind check resources occupied by the downlink control information for scheduling multiple cells will be small. Therefore, when the reference cell in the first cell set includes one cell, the blind check resources occupied by the legacy DCI configured in each cell in the first cell set can be first 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 to 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, the blind check resources occupied by all DCIs configured in each cell are taken as an example. The fewer the blind check resources occupied by all DCIs configured for a cell, the lower the complexity of the blind check for the terminal. Therefore, if the reference cell in the first cell set includes one cell, the blind check resources occupied by all DCIs configured in each cell in the first cell set can be first 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 blind check for the terminal on the reference cell.

[0050] For example, the first cell set includes cells Cell#1, Cell#2, Cell#3, and Cell#4, and for these four cells, the blind check resources occupied by the DCI set in each cell can be determined as follows: for example, the blind check resource occupied by the DCI set in Cell#1 is R1, the blind check resource occupied by the DCI set in Cell#2 is R2, the blind check resource occupied by the DCI set in Cell#3 is R3, and the blind check resource occupied by the DCI set in Cell#4 is R4.The order of these four blind check resources is R2, R3, R4, and R1, that is, if the blind check resource R2 occupied by the DCI set in Cell#2 is the fewest, Cell#2 can be selected as the reference cell, and downlink control information for scheduling multiple cells is used to determine the blind check resources to be occupied.

[0051] It should be noted that, in the embodiments of the present disclosure, for a cell, determining the blind check resource occupied by the DCI configured for the cell includes, but is not limited to, the following two ways: Method 1: Determine a search space configured for a cell, and sum up all blind check resources (e.g., PDCCH candidates) of DCI configured in the search space; Method 2: Determine a search space configured for a cell, and sum up blind check resources of corresponding DCIs within a specific time unit in the search space, where the specific time unit may be specified by a predefined rule or indicated by a network device, and may be one or more frames, one or more subframes, one or more slots, one or more symbols, and / or one or more PDCCH spans.

[0052] In one embodiment, taking the blind check resources occupied by the legacy DCI configured in each cell as an example, the larger the blind check resources occupied by the legacy DCI configured for a cell, the smaller the blind check resources occupied by the downlink control information for scheduling multiple cells. Therefore, when the reference cell in the first cell set includes multiple cells, first determine the blind check resources occupied by the legacy DCI configured for each cell in the first cell set, and then determine the multiple 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 terminal's blind check capability for downlink control information for scheduling multiple cells in the reference cell.

[0053] In one embodiment, the blind check resources occupied by all DCIs configured in each cell are taken as an example. The fewer the blind check resources occupied by all DCIs configured for a cell, the lower the complexity of the blind check of the UE. Therefore, when the reference cell in the first cell set includes multiple cells, the blind check resources occupied by all DCIs configured in each cell in the first cell set can be determined first, and then the multiple cells in the first cell set with the smallest blind check resources occupied by all DCIs can be determined as reference cells in the first cell set. This is advantageous for ensuring the UE's ability to blind check downlink control information for scheduling multiple cells in the 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, the blind check resources occupied by the DCI set in each cell can be determined as follows: for example, the blind check resource occupied by the DCI set in Cell#1 is R1, the blind check resource occupied by the DCI set in Cell#2 is R2, the blind check resource occupied by the DCI set in Cell#3 is R3, and the blind check resource occupied by the DCI set in Cell#4 is R4. The order of these four blind check resources is R2, R3, R4, and R1, i.e., the blind check resource R2 occupied by the DCI set in Cell#2 is the smallest, followed by the blind check resource R3 occupied by the DCI set in 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 to be occupied. Determining the blind check resource occupied by the DCI configured in the cell has been described above and will not be further described here.

[0055] In one embodiment, the DCI comprises: At least one of conventional DCIs, i.e., legacy DCIs, for example, DCI 0_0, DCI 0_1, DCI 1_0, DCI 1_1, DCI 2_0, DCI 2_1, etc., is included; All DCI configured in the cell includes, for example, legacy DCI and downlink control information for scheduling multiple cells.

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

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

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

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

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

[0061] It should be noted that the above-mentioned embodiments of determining a reference cell in the first cell set can be realized individually and can be combined as necessary. For example, a cell can be determined in which a search space corresponding to downlink control information for scheduling multiple cells in the first cell set is set. When multiple cells are determined, the cell with the least blind check resources occupied by the DCIs set in each of the multiple cells can be further determined as the reference cell.

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

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

[0064] For example, the first cell set includes Cell#1, Cell#2, Cell#3, and Cell#4.

[0065] If the determined reference cells are Cell#1 and Cell#2, the blind check resources occupied by downlink control information for scheduling multiple cells in Cell#1 can be determined, and the blind check resources occupied by downlink control information for scheduling multiple cells in Cell#2 can be determined.

[0066] When all the cells in the first cell set are determined as reference cells, it is possible to determine the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#1, to determine the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#2, to determine the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#3, and to determine the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#4.

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

[0068] When determining the blind check resources occupied by the downlink control information for scheduling the plurality of cells set in each of the reference cells in the first cell set, the determination results of each cell (i.e., the determined blind check resources) can be processed by a quantization coefficient (e.g., by algorithmic processing such as multiplication, division, addition, subtraction, square root, or logarithm of the determination results based on the quantization coefficient) to obtain the final blind check resources. For example, the determination results of a certain cell can be multiplied by the quantization coefficient to obtain the final determined blind check resources of the cell.

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

[0070] For example, the first cell set includes Cell#1, Cell#2, Cell#3, and Cell#4.

[0071] When the determined reference cells are Cell#1 and Cell#2, the quantization coefficient is 1 / 2. The determination result A for determining the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#1 can be multiplied by 1 / 2 to obtain A / 2, which is the blind check resources occupied by the downlink control information for scheduling multiple cells determined in Cell#1, and the determination result B for determining the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#2 can be multiplied by 1 / 2 to obtain B / 2, which is the blind check resources 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 determining the blind check resources to be occupied by the 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 resources to be occupied by the downlink control information for scheduling multiple cells in Cell#1; decision result B determining the blind check resources to be occupied by the 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 resources to be occupied by the downlink control information for scheduling multiple cells in Cell#1; decision result C determining the blind check resources to be occupied by the 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 resources to be occupied by the downlink control information for scheduling multiple cells in Cell#3; and decision result D determining the blind check resources to be occupied by the 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 resources to be occupied by the downlink control information for scheduling multiple cells in Cell#4.

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

[0074] In one embodiment, if at least one cell set is in multiple cell sets, there may be intersecting cells (including the same cell) in the multiple cell sets, or there may be no intersecting cells (not including the same cell).

[0075] For example, consider two cell sets.

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

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

[0078] When an intersection cell exists between multiple cell sets, the same reference cell may be determined when determining a reference cell for each first cell set among the multiple cell sets. In this case, the same reference cell may be used to determine blind check resources to be occupied when downlink control information for scheduling multiple cells schedules cells in each first cell set where an intersection exists with the same reference cell. In this case, the blind check resources occupied by the downlink control information for scheduling multiple cells determined using 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 cell set.

[0079] For example, if the reference cell in the above set #1 is determined to be Cell #1, and the reference cell in the above set #2 is also determined to be 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 resources 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 resources occupied by the downlink control information for scheduling multiple cells when scheduling multiple cells in set #2, for example, B. The blind check resources occupied by the downlink control information for scheduling multiple cells determined in Cell #1 are the sum of A and B.

[0080] It should be noted that in the embodiments of the present disclosure, for a cell, determining the blind check resource occupied by the downlink control information for scheduling multiple cells configured for the cell includes, but is not limited to, the following two ways: Method 1: Determine a search space configured for a cell, and sum up all blind check resources (e.g., PDCCH candidates) of downlink control information for scheduling multiple cells in the search space; Method 2: Determine a search space configured for cells, and sum up blind check resources of downlink control information for scheduling multiple cells within a specific time unit in the search space, where the specific time unit may be specified 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, when the at least one cell set includes a plurality of cell sets and there is an intersection cell between the plurality of cell sets, for each first cell set of the at least one cell set, determining a reference cell in the first cell set includes: For each first cell set of the plurality of first cell sets, determining a reference cell in the first cell set, wherein the reference cell in each first cell set is different.

[0082] In one embodiment, as can be seen from the above embodiment, when 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. When downlink control information for scheduling multiple cells using the same reference cell schedules a cell in each first cell set that has an intersecting cell with the same reference cell, it is necessary to determine the blind check resource to occupy. This is advantageous for simplifying the configuration logic, but it imposes a heavy burden on the determination of the same reference cell.

[0083] Therefore, considering the cell determination burden angle, when at least one cell set in this embodiment includes multiple cell sets and there are intersecting cells between the multiple cell sets, different reference cells can be determined in each first cell set, thereby avoiding the determination burden of a certain reference cell from being too large.

[0084] For example, for multiple cell sets: First, a sorting method (which may be called priority) for cell sets may be defined, for example, sorting cell sets according to the smallest cell set identifier (ID), or sorting cell sets according to the largest cell set identifier, or sorting according to the largest blind check resource occupied by DCIs set in one or more cells within a cell set, or sorting according to the smallest blind check resource occupied by DCIs set in one or more cells within a cell set. The following description will be mainly given as an example of sorting cell sets according to the smallest cell set identifier.

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

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

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

[0090] This makes it possible to determine the reference cell in each of the three first cell sets, and ensure that the reference cell in each first cell set is different.

[0091] The following provides an exemplary description of a method for determining at least one cell set corresponding to downlink control information for scheduling multiple cells according to some embodiments.

[0092] In one embodiment, the step of determining at least one cell set corresponding to downlink control information for scheduling the plurality of cells comprises: determining configuration parameters for each cell in the plurality of cells (e.g., cells for which downlink control information for scheduling a plurality of cells is schedulable), the configuration parameters including, but not limited to, a set identifier, a cell identifier, a number, and a carrier indicator field (CIF); determining that cells having the same configuration parameters belong to a cell set corresponding to downlink control information for scheduling multiple cells.

[0093] For example, assuming four cells are Cell#1, Cell#2, Cell#3, and Cell#4, and the configuration parameters include a CIF, the CIF configured for each of these four cells can be determined (for example, based on radio resource control (RRC) signaling). For example, if the CIF configured for Cell#1 is 01, the CIF configured for Cell#2 is 01, the CIF configured for Cell#3 is 02, and the CIF configured for Cell#4 is 02, it can be determined that Cell#1 and Cell#2 have the same CIF, and Cell#3 and Cell#4 have the same CIF, and Cell#1 and Cell#2 are divided into a cell set {Cell#1, Cell#2} corresponding to downlink control information for scheduling one plurality of cells, and Cell#3 and Cell#4 are divided into a cell set {Cell#3, Cell#4} corresponding to downlink control information for scheduling another plurality of cells.

[0094] In one embodiment, the step of determining at least one cell set corresponding to downlink control information for scheduling the plurality of cells comprises: The method 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 first cells; determining a target cell group to which the first cell belongs among the plurality of cell groups and a set of cell groups belonging to the target cell group; and determining a cell set corresponding to the set of cell groups.

[0095] The terminal may receive indication information transmitted by a network device in a plurality of first cells, where the indication information may indicate an association relationship between a value of a carrier indication field (CIF) corresponding to the first cell in which the terminal is located when receiving the indication information and a scheduling cell identifier, and the terminal may determine a plurality of cell groups based on the association relationship corresponding to each first cell, where the association relationship may specifically be an association relationship between a value of an in-scheduling-cell carrier indication field (cif-InScheduingCell) and a scheduling cell identifier.

[0096] The terminal may determine whether the first cell is a scheduling cell according to the downlink control information for scheduling the plurality of cells received at the second cell based on the following manner: The information element (IE) serving cell configuration (ServingCellConfig) in the RRC message is determined, then the cross-carrier scheduling configuration (CrossCarrierSchedulingConfig) in the serving cell configuration is determined, then the scheduling cell information (schedulingCellInfo) is determined in the cross-carrier scheduling configuration, and if the schedulingCellInfo indication value is other, then the scheduling cell identifier (schedulingCellId) and cif-InScheduingCell in the 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 value of cif-InScheduingCell set in the RRC message is the same as the value of CIF in the downlink control information for scheduling multiple cells received by the second cell, it can be determined that the downlink control information for scheduling multiple cells received by the second cell is used to schedule the first cell.

[0098] The association relationship may define correspondence relationships between multiple carrier indication field values ​​and multiple scheduling cell identifiers, and is not limited to one carrier indication field value 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 relationship, the downlink control information for scheduling multiple cells is advantageous to improve scheduling flexibility for a first cell. For example, the network device may dynamically adjust 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 relationship corresponding to the first cell to be scheduled as needed.

[0099] FIG. 7 is a schematic diagram of another application scene according to an embodiment of the present disclosure.

[0100] As shown in Figure 7, taking three cells Cell#0 (cell identifier is 0), Cell#1 (cell identifier is 1) and Cell#2 (cell identifier is 2) as an example, the network device conveys the indication information via an RRC message.

[0101] In the network device, the association relationship carried in the RRC message sent to the terminal in Cell#0 is table1-0, the association relationship carried in the RRC message sent to the terminal in Cell#1 is table1-1, and the association relationship carried in the RRC message sent to the terminal in Cell#2 is table1-2.

[0102] The association relationship included in table 1-0 is that the scheduling cell identifier corresponding to the value 0 of the carrier indication field is 2; The association relationship included in table 1-1 is that when the scheduling cell identifier is 0 and the scheduling cell identifier is 0 and the value of the carrier indication field is 2, the network device can schedule a first cell (e.g., Cell #1) when the value of the CIF in the downlink control information for scheduling multiple cells transmitted 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) when the value of the CIF in the downlink control information for scheduling multiple cells transmitted to the terminal by the second cell whose cell identifier is 0 is 2. Here, the value of the CIF may range from 0 to 7, and of course, can be adjusted as needed.

[0103] The association relationship included in table 1-2 is that the scheduling cell identifier 0 corresponds to the value of the carrier indication field of 1, and the scheduling cell identifier 0 corresponds to the value of the carrier indication field of 3. Then, when the value of the CIF in the downlink control information for scheduling multiple cells transmitted to the terminal by the second cell whose network device cell identifier is 0 is 1, it is possible to realize scheduling of the first cell (e.g., Cell #2), and when the value of the CIF in the downlink control information for scheduling multiple cells transmitted to the terminal by the second cell whose cell identifier is 2 is 3, it is also possible to realize scheduling of the first cell (e.g., Cell #2).

[0104] Here, since table1-0 is the association relationship received by the 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 the scheduling Cell#0 itself, so the association relationship corresponding to Cell#0 can additionally include, in addition to the correspondence relationships included in table1-0, that the scheduling cell identifier corresponding to a carrier indication field value of 0 is 0, that the scheduling cell identifier corresponding to a carrier indication field value of 1 is 0, that the scheduling cell identifier corresponding to a carrier indication field value of 2 is 0, and that the scheduling cell identifier corresponding to a carrier indication field value of 3 is 0.

[0105] 6, the value of the carrier indication field and the scheduling cell identifier can be set, but 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 four rows shown in the figure, and the number of rows can be reduced or increased as needed.

[0106] The carrier indication field may be determined based on the above-mentioned relationship, and when the value of the carrier indication field is 0 (00), the downlink control information for scheduling multiple cells may schedule Cell #0, when the value of the carrier indication field is 1 (01), the downlink control information for scheduling multiple cells may schedule Cell #0, Cell #1, and Cell #2, when the value of the carrier indication field is 2 (10), the downlink control information for scheduling multiple cells may schedule Cell #0 and Cell #1, when the value of the carrier indication field is 3 (11), the downlink control information for scheduling multiple cells may schedule Cell #0 and Cell #2. Thus, the terminal determines that the relationship between the determined value of the carrier indication field and the scheduling cell is as shown in Table 1: [Table 1] Table 1 Here, the cell groups are cell groups each composed of cells corresponding to the value of each carrier indication field (which may also be indicated by the value of other fields) in the association relationship set indicated by the indication information received by each first cell, and the multiple cell groups are {0}, {0, 1, 2}, {0, 1}, {0, 2}, as shown in Table 1. For convenience, only cell identifiers are listed in the set.

[0107] Each element in the table shown in all the embodiments of the present disclosure exists independently, and although these elements are exemplarily listed in the same table, 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 therein is a value that does not depend on the values ​​of other elements in the table. Therefore, those skilled in the art can understand that the value of each element in the table is an independent embodiment.

[0108] Since there is a cell group set that also belongs to a cell group, the cell group set can correspond to a cell set; therefore, after determining the multiple cell groups, the terminal can further determine a target cell group that belongs to the multiple cell groups of the first cell; and after further determining the cell group set that belongs to the target cell group and the cell set corresponding to the cell group set, the terminal can determine a cell set where the first cell belongs to the determined cell set, i.e., corresponds to downlink control information for scheduling the multiple cells.

[0109] Here, the cells included in the cell groups in different cell group sets are different. For example, if cell group set #1 includes cell group #1 and cell group #2, and cell group set #2 includes cell group #3 and cell group #4, 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 cell set corresponding to the cell group set includes the steps of determining at least one cell group set based on the plurality of cell groups, wherein a first cell group in a first cell group set is the same cell as a second cell group in at least the first cell group set; and determining that cells included in a cell group in one cell group set of the at least one cell group set constitute one cell set.

[0111] After determining a plurality of cell groups, the terminal can determine a cell group set based on the plurality of cell groups, where cell groups including the same cells can be divided into the same cell group set, for example, if a first cell group and a second cell group include the same cells, the first cell group and the second cell group can be divided into the same cell group set, for example, divided into the first cell group set.

[0112] Next, the cell groups in the first cell group set that contain the same cells can be determined in other cell groups, and the determined cell groups can then be divided into the first cell group set. By analogy, the determination of the first cell group set can be completed. Furthermore, other cell group sets can be determined based on the method for determining the first cell group set.

[0113] Note that the first cell group and the second cell group in the same cell group set are different, and the first cell group and the second cell group do not refer to specific cells but to any one cell group in one cell group set.

[0114] For example, let's determine the 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, any cell group within it can be considered. For example, first consider cell group {0, 1, 2, 3}. If it is determined that cell group {3}, cell group {3, 4, 5, 6}, and cell group {0, 1, 2, 3} contain the same cell Cell#3, then these three cell groups {3}, {3, 4, 5, 6}, and {0, 1, 2, 3} are divided into the same cell group set, which is called, for example, the first cell group set.

[0115] Furthermore, in other cell groups, any cell group in the first cell group set can be re-determined 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 cell group contain the same cells Cell#5 and Cell#6, and cell group {5, 6, 7} can also be divided into the first cell group set.

[0116] Since the cell groups {8, 9} and {8} do not contain the same cell as any other cell group in the first cell group set, the determination of the first cell group set is completed, and the second cell group set can be determined subsequently. For example, it can be determined that the second cell group set includes the cell groups {8, 9} and {8} according to the above method.

[0117] For a cell group, for example, the instruction information received by Cell#1, Cell#2, Cell#3, and Cell#4 includes that the cell set identifier is 1, and the instruction information received by Cell#5, Cell#6, Cell#7, and Cell#8 includes that the cell set identifier is 2, and the terminal determines the cell set (cell set id=1) to which Cell#1, Cell#2, Cell#3, and Cell#4 belong with identifier 1, and determines the cell set (cell set id=2) to which Cell#5, Cell#6, Cell#7, and Cell#8 belong with identifier 2.

[0118] Subsequently, the downlink control information for scheduling a plurality of cells received by the UE at the scheduling cell is downlink control information for scheduling a plurality of cells Cell #1, Cell #2, Cell #3, and Cell #4, and can be used to schedule a plurality of cells Cell #2 and Cell #3. Downlink control information for scheduling another plurality of cells received at the scheduling cell can be used to schedule a plurality of cells Cell #5, Cell #6, Cell #7, and Cell #8, and can also be used to schedule a plurality of cells Cell #6 and 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 cells to be scheduled by the downlink control information for scheduling a plurality of cells transmitted by different cells.

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

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

[0121] As shown in Figure 8, take the first cell group set and the second cell group set determined in the above embodiment as an example, 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] When it can be determined that the cells included in the cell groups in the first cell group set are Cell#0, Cell#1, Cell#2, Cell#3, Cell#4, Cell#5, Cell#6, and Cell#7, it can be determined that the cell set composed of these cells is {0, 1, 2, 3, 4, 5, 6, 7}, i.e., the cell set corresponding to the first cell group set is {0, 1, 2, 3, 4, 5, 6, 7}, and similarly, it can be determined that the cell set corresponding to the second cell group set is {8, 9}. At least one cell set corresponding to the downlink control information for scheduling multiple cells includes the cell set {0, 1, 2, 3, 4, 5, 6, 7} and the cell set {8, 9}.

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

[0124] Here, the method of determining the plurality of cell groups is similar to that of the previous embodiment and will not be described further here. The difference between this embodiment and the previous embodiment is that the cell groups are directly determined as cell sets without determining the cell sets belonging to the cell groups. For example, after determining Table 1 based on the indication information, the plurality of cell groups {0}, {0, 1, 2}, {0, 1}, and {0, 2} in Table 1 can be respectively determined as cell sets. That is, at least one cell set corresponding to the downlink control information for scheduling the plurality of cells includes the four sets {0}, {0, 1, 2}, {0, 1}, and {0, 2}.

[0125] 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, and the network device can communicate with a terminal, including but not limited to a base station in a communication system, such as a 4G base station, a 5G base station, or a 6G base station. The terminal can include but is not limited to a communication device, such as a mobile phone, a tablet, a wearable device, a sensor, or an IoT device.

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

[0127] In one embodiment, when the at least one cell set includes a plurality of cell sets, the plurality of cell sets may include the same cell, or the plurality of cells may not include the same cell.

[0128] In one embodiment, the downlink control information for scheduling multiple cells may be abbreviated as MC-DCI, for example, where MC-DCI is used for scheduling multiple cells, and specifically refers to data for scheduling multiple cells, such as PUSCH, PDSCH, etc., for scheduling one or more cells among the multiple cells, thereby realizing scheduling of multiple cells via one DCI, where 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 format of a legacy DCI (e.g., DCI format 0_0, DCI format 0_1, etc.), or may use a newly defined format, e.g., DCI format 0_3, DCI format 1_3, etc.

[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 Identity C-RNTI, or can also be scrambled with a newly defined RNTI.

[0131] The downlink control information for scheduling multiple cells can be used to schedule multiple cells, and compared with the DCI for scheduling a single cell among legacy DCIs, the downlink control information for scheduling multiple cells contains relatively more information, and therefore the occupied blind check resources are also relatively more. Although the UE can receive downlink control information for scheduling multiple cells (scheduled cell) used for scheduling multiple cells from the scheduling cell, determining all occupied blind check resources based on the scheduling cell places too much burden on the scheduling cell, which is disadvantageous in ensuring good blind check efficiency and blind check performance.

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

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

[0134] The downlink control information for scheduling a plurality of cells can schedule a plurality of cells, for example, a plurality of cells in a first cell set. In this case, this embodiment can determine a reference cell in the first cell set, and determine blind check resources to be occupied when the downlink control information for scheduling a plurality of cells schedules the cells in the first cell set from the reference cell, which is advantageous for subsequently ensuring blind check efficiency and blind check performance for the downlink control information by the UE.

[0135] After the terminal determines a reference cell in a first cell set, it can determine blind check resources to be occupied when downlink control information for scheduling the plurality of cells schedules the cells in the first cell set from the reference cell in the first cell set. If the determined blind check resources exceed the blind check capacity, it can drop some of the blind check resources corresponding to the configured DCI, and do not perform blind check of the DCI using the dropped some of the blind check resources.

[0136] Meanwhile, the network device determines a reference cell in a first cell set, and determines, from the reference cell in the first cell set, blind check resources that the downlink control information for scheduling the plurality of cells occupies when scheduling the cells in the first cell set. This further enables the network device to determine blind check resources that can be subsequently discarded by the terminal, which is advantageous in improving the flexibility and effectiveness of scheduling.

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

[0138] The reference cell in the first cell set may be one cell or multiple cells, and these two cases will be described below using examples.

[0139] In one embodiment, the blind check resource comprises: Candidate physical downlink control channels (PDCCH candidates); and a control channel element (CCE).

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

[0141] The following describes exemplary methods for determining a reference cell in the first cell set according to some embodiments. Here, the method for determining a reference cell in the first cell set may be determined based on a predefined rule (e.g., protocol agreement) or an instruction from a network device, but the present disclosure is not limited thereto.

[0142] In one embodiment, determining a reference cell in the first set of cells includes 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 cell set, a cell identifier (Cell ID) of each cell in the first cell set can be first determined, and then a reference cell can be selected in a cell set included in the first cell set based on the cell identifier of each cell.

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

[0145] In one embodiment, when the reference cell in the first cell set includes one cell, determining the reference cell in the first cell set based on the cell identifier may determine the cell with the largest cell identifier as the reference cell in the first cell set, or may determine the cell with the smallest cell identifier as the reference cell in the first cell set.

[0146] For example, the first cell set 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 cell set, Cell#4 can be determined as the reference cell in the first cell set, and when the cell with the smallest cell identifier is determined as the reference cell in the first cell set, Cell#1 can be determined as the reference cell in the first cell set.

[0147] In one embodiment, when the 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 determine multiple cells in the first cell set in descending order of identifiers as reference cells in the first cell set, or can determine multiple cells in the first cell set in descending order of cell identifiers as reference cells in the first cell set.

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

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

[0150] For example, if the first cell set includes four cells, Cell#1, Cell#2, Cell#3, and Cell#4, the first order is to sort the cells in ascending order according to the Cell ID, and the sorting result is Cell#4, Cell#3, Cell#2, and Cell#1. For example, if the cell with sort number 3 is determined as the reference cell for the first cell set, and it is known that Cell#2 is the cell with sort number 3, then Cell#2 can be determined as the reference cell for the first cell set.

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

[0152] In one embodiment, when determining a reference cell in a first cell set, first, the blind check resource that the DCI occupies for each cell in the first cell set can be determined, and then the reference cell in the first cell set can be determined based on the blind check resource that the DCI occupies for 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 in each cell in the first cell set includes, if the reference cell in the first cell set includes one cell, determining the cell in the first cell set with the fewest blind check resources occupied by the DCI 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 in order of the smallest blind check resources occupied by the DCI (which is the DCI set for each cell in the first cell set) in the first cell set as the reference cell in the first cell set.

[0154] Here, the blind check resource occupied by the DCI configured in each cell may be the blind check resource occupied by the legacy DCI configured in each cell, or may be the blind check resource occupied by all DCI configured in each cell (e.g., including the legacy DCI and downlink control information for scheduling multiple cells).

[0155] In one embodiment, taking the blind check resources occupied by the legacy DCI configured in each cell as an example, if the blind check resources occupied by the legacy DCI configured for a cell are large, under certain conditions, the blind check resources occupied by the downlink control information for scheduling multiple cells will be small. Therefore, when the reference cell in the first cell set includes one cell, it is possible to first determine the blind check resources occupied by the legacy DCI configured 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 to 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, the blind check resources occupied by all DCIs configured in each cell are taken as an example. The fewer the blind check resources occupied by all DCIs configured for a cell, the lower the complexity of the blind check for the terminal. Therefore, if the reference cell in the first cell set includes one cell, the blind check resources occupied by all DCIs configured in each cell in the first cell set can be first 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 blind check for the terminal on the reference cell.

[0157] For example, the first cell set includes cells Cell#1, Cell#2, Cell#3, and Cell#4, and for these four cells, the blind check resources occupied by the DCI set in each cell can be determined as follows: for example, the blind check resource occupied by the DCI set in Cell#1 is R1, the blind check resource occupied by the DCI set in Cell#2 is R2, the blind check resource occupied by the DCI set in Cell#3 is R3, and the blind check resource occupied by the DCI set in Cell#4 is R4.The order of these four blind check resources is R2, R3, R4, and R1, that is, if the blind check resource R2 occupied by the DCI set in Cell#2 is the fewest, Cell#2 can be selected as the reference cell, and downlink control information for scheduling multiple cells is used to determine the blind check resources to be occupied.

[0158] It should be noted that, in the embodiments of the present disclosure, for a cell, determining the blind check resource occupied by the DCI configured for the cell includes, but is not limited to, the following two ways: Method 1: Determine a search space configured for a cell, and sum up all blind check resources (e.g., PDCCH candidates) of DCI in the search space; Method 2: Determine a search space configured for a cell, and sum up blind check resources of corresponding DCIs within a specific time unit in the search space, where the specific time unit may be specified by a predefined rule or indicated by a network device, and may be one or more frames, one or more subframes, one or more slots, one or more symbols, and / or one or more PDCCH spans.

[0159] In one embodiment, taking the blind check resources occupied by the legacy DCI configured in each cell as an example, the larger the blind check resources occupied by the legacy DCI configured for a cell, the smaller the blind check resources occupied by the downlink control information for scheduling multiple cells. Therefore, when the reference cell in the first cell set includes multiple cells, the blind check resources occupied by the legacy DCI configured in each cell in the first cell set can be first determined, and then the 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.

[0160] In one embodiment, the blind check resources occupied by all DCIs configured in each cell are taken as an example. The fewer the blind check resources occupied by all DCIs configured for a cell, the lower the complexity of the blind check of the UE. Therefore, when the reference cell in the first cell set includes multiple cells, the blind check resources occupied by all DCIs configured in each cell in the first cell set can be determined first, and then the multiple cells in the first cell set with the smallest blind check resources occupied by all DCIs can be determined as reference cells in the first cell set. This is advantageous for ensuring the UE's ability to blind check downlink control information for scheduling multiple cells in the 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, the blind check resources occupied by the DCI set in each cell can be determined as follows: for example, the blind check resource occupied by the DCI set in Cell#1 is R1, the blind check resource occupied by the DCI set in Cell#2 is R2, the blind check resource occupied by the DCI set in Cell#3 is R3, and the blind check resource occupied by the DCI set in Cell#4 is R4. The order of these four blind check resources is R2, R3, R4, and R1, i.e., the blind check resource R2 occupied by the DCI set in Cell#2 is the smallest, followed by the blind check resource R3 occupied by the DCI set in 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 to be occupied. Determining the blind check resource occupied by the DCI configured in the cell has been described above and will not be further described here.

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

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

[0164] In one embodiment, when the downlink control information for scheduling the multiple cells schedules the multiple cells in a first cell set, a downlink control information size (i.e., the number of bits to occupy) budget for scheduling the multiple cells can be determined by at least one cell among the multiple cells, and the at least one cell specifically aligns the size of the DCI (DCI including the downlink control information for scheduling the multiple cells).

[0165] When selecting a reference cell, at least one cell for determining the size budget of the downlink control information for scheduling the multiple cells can be selected as the reference cell, and in the process of scheduling the multiple cells using the downlink control information for scheduling the multiple cells, the decision operations performed by the cells that need to be scheduled can be concentrated in one cell, which is advantageous in simplifying the configuration logic for the cells.

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

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

[0168] It should be noted that the above-mentioned embodiments of determining a reference cell in the first cell set can be realized individually and can be combined as necessary. For example, a cell can be determined in which a search space corresponding to downlink control information for scheduling multiple cells in the first cell set is set. When multiple cells are determined, the cell with the least blind check resources occupied by the DCIs set in each of the multiple cells can be further determined as the reference cell.

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

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

[0171] For example, the first cell set includes Cell#1, Cell#2, Cell#3, and Cell#4.

[0172] If the determined reference cells are Cell#1 and Cell#2, the blind check resources occupied by downlink control information for scheduling multiple cells in Cell#1 can be determined, and the blind check resources occupied by downlink control information for scheduling multiple cells in Cell#2 can be determined.

[0173] When all the cells in the first cell set are determined as reference cells, it is possible to determine the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#1, to determine the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#2, to determine the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#3, and to determine the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#4.

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

[0175] When determining the blind check resources occupied by the downlink control information for scheduling the plurality of cells set in each of the reference cells in the first cell set, the determination results of each cell (i.e., the determined blind check resources) can be processed by a quantization coefficient (e.g., by algorithmic processing such as multiplication, division, addition, subtraction, square root, or logarithm of the determination results based on the quantization coefficient) to obtain the final blind check resources. For example, the determination results of a certain cell can be multiplied by the quantization coefficient to obtain the final determined blind check resources of the cell.

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

[0177] For example, the first cell set includes Cell#1, Cell#2, Cell#3, and Cell#4.

[0178] When the determined reference cells are Cell#1 and Cell#2, the quantization coefficient is 1 / 2. The determination result A for determining the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#1 can be multiplied by 1 / 2 to obtain A / 2, which is the blind check resources occupied by the downlink control information for scheduling multiple cells determined in Cell#1, and the determination result B for determining the blind check resources occupied by the downlink control information for scheduling multiple cells in Cell#2 can be multiplied by 1 / 2 to obtain B / 2, which is the blind check resources 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 determining the blind check resources to be occupied by the 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 resources to be occupied by the downlink control information for scheduling multiple cells in Cell#1; decision result B determining the blind check resources to be occupied by the 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 resources to be occupied by the downlink control information for scheduling multiple cells in Cell#1; decision result C determining the blind check resources to be occupied by the 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 resources to be occupied by the downlink control information for scheduling multiple cells in Cell#3; and decision result D determining the blind check resources to be occupied by the 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 resources to be occupied by the downlink control information for scheduling multiple cells in Cell#4.

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

[0181] In one embodiment, if at least one cell set is in multiple cell sets, there may be intersecting cells (including the same cell) in the multiple cell sets, or there may be no intersecting cells (not including the same cell).

[0182] For example, consider two cell sets.

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

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

[0185] When an intersection cell exists between multiple cell sets, the same reference cell may be determined when determining a reference cell for each first cell set among the multiple cell sets. In this case, the same reference cell may be used to determine blind check resources to be occupied when downlink control information for scheduling multiple cells schedules cells in each first cell set where an intersection exists with the same reference cell. In this case, the blind check resources occupied by the downlink control information for scheduling multiple cells determined using 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 cell set.

[0186] For example, if the reference cell in the above set #1 is determined to be Cell #1, and the reference cell in the above set #2 is also determined to be 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 resources 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 resources occupied by the downlink control information for scheduling multiple cells when scheduling multiple cells in set #2, for example, B. The blind check resources occupied by the downlink control information for scheduling multiple cells determined in Cell #1 are the sum of A and B.

[0187] It should be noted that in the embodiments of the present disclosure, for a cell, determining the blind check resource occupied by the downlink control information for scheduling multiple cells configured for the cell includes, but is not limited to, the following two ways: Method 1: Determine a search space configured for a cell, and sum up all blind check resources (e.g., PDCCH candidates) of downlink control information for scheduling multiple cells in the search space; Method 2: Determine a search space configured for cells, and sum up blind check resources of downlink control information for scheduling multiple cells within a specific time unit in the search space, where the specific time unit may be specified 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, when the at least one cell set includes a plurality of cell sets and an intersection cell exists between the plurality of cell sets, determining, for each first cell set of the at least one cell set, a reference cell in the first cell set includes determining, for each first cell set of the plurality of first cell sets, a reference cell in the first cell set, and the reference cell in each first cell set is different.

[0189] In one embodiment, as can be seen from the above embodiment, when 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. When downlink control information for scheduling multiple cells using the same reference cell schedules a cell in each first cell set that has an intersecting cell with the same reference cell, it is necessary to determine the blind check resource to occupy. This is advantageous for simplifying the configuration logic, but it imposes a heavy burden on the determination of the same reference cell.

[0190] Therefore, considering the cell determination burden angle, when at least one cell set in this embodiment includes multiple cell sets and there are intersecting cells between the multiple cell sets, different reference cells can be determined in each first cell set, thereby avoiding the determination burden of a certain reference cell from being too large.

[0191] For example, for multiple cell sets: First, a sorting method (which may be called priority) for cell sets may be defined, for example, sorting cell sets according to the smallest cell set identifier (ID), or sorting cell sets according to the largest cell set identifier, or sorting according to the largest blind check resource occupied by DCIs set in one or more cells within a cell set, or sorting according to the smallest blind check resource occupied by DCIs set in one or more cells within a cell set. The following description will be mainly given as an example of sorting cell sets according to the smallest cell set identifier.

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

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

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

[0197] This makes it possible to determine the reference cell in each of the three first cell sets, and ensure that the reference cell in each first cell set is different.

[0198] The following provides an exemplary description of a method for determining at least one cell set corresponding to downlink control information for scheduling multiple cells according to some embodiments.

[0199] In one embodiment, the step of determining at least one cell set corresponding to downlink control information for scheduling the plurality of cells comprises: determining configuration parameters for each cell in a plurality of cells (e.g., cells for which downlink control information for scheduling a plurality of cells is schedulable); determining that cells having the same configuration parameters belong to a cell set corresponding to downlink control information for scheduling multiple cells.

[0200] For example, taking four cells Cell#1, Cell#2, Cell#3, and Cell#4 as an example where the configuration parameters include a carrier indicator field (CIF), the CIF configured for each of these four cells can be determined (for example, determined based on radio resource control (RRC) signaling). For example, if the CIF configured for Cell#1 is 01, the CIF configured for Cell#2 is 01, the CIF configured for Cell#3 is 02, and the CIF configured for Cell#4 is 02, it can be determined that Cell#1 and Cell#2 have the same CIF and Cell#3 and Cell#4 have the same CIF, and Cell#1 and Cell#2 are divided into a cell set {Cell#1, Cell#2} corresponding to downlink control information for scheduling one plurality of cells, and Cell#3 and Cell#4 are divided into a cell set {Cell#3, Cell#4} corresponding to downlink control information for scheduling another plurality of cells.

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

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

[0203] Here, the function of the association relationship will be described in the embodiment corresponding to the terminal side in the preceding sentence, and will not be further described here. The manner in which the network device determines a plurality of cell groups is opposite to the manner in which the terminal determines a plurality of cells, on the other hand, the network device can determine a plurality of cell groups before sending the indication information and indicate them to the terminal through the indication information, on the other hand, the terminal can determine a plurality of cells only after receiving the indication information. In addition, the manner in which the network device determines at least one cell set corresponding to the downlink control information for scheduling a plurality of cells also corresponds to the embodiment on the terminal side, and will not be described here either.

[0204] Corresponding to the above-mentioned embodiment of the cell determination method, the present disclosure further provides an embodiment of a cell determination apparatus.
