Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and more specifically, to cell determination methods, cell determination apparatus, cell determination systems, communication devices, and computer-readable storage media. Background Technology

[0002] In related technologies, scheduling a single downlink control information (DCI) within a cell only allows scheduling data from one cell, such as scheduling the Physical Uplink Shared Channel (PUSCH) or the Physical Downlink Shared Channel (PDSCH). However, with the gradual fragmentation of frequency resources, the demand for simultaneously scheduling data from multiple cells will gradually increase. Summary of the Invention

[0003] In view of the above, embodiments of this disclosure provide a cell determination method, a cell determination apparatus, a cell determination system, a communication device, and a computer-readable storage medium to solve the technical problems in the related art.

[0004] According to a first aspect of the present disclosure, a cell determination method is proposed, executed by a terminal, the method comprising: determining at least one cell set corresponding to downlink control information for scheduling multiple cells; and for each first cell set in the at least one cell set, determining a reference cell in the first cell set, wherein the blind detection resources occupied by the downlink control information for scheduling multiple cells when scheduling cells in the first cell set are determined on the reference cell in the first cell set.

[0005] According to a second aspect of the present disclosure, a cell determination method is proposed, executed by a network device, the method comprising: determining at least one set of cells corresponding to downlink control information for scheduling multiple cells; and for each first set of cells in the at least one set of cells, determining a reference cell in the first set of cells, wherein the blind detection resources occupied by the downlink control information for scheduling multiple cells when scheduling cells in the first set of cells are determined on the reference cell in the first set of cells.

[0006] According to a third aspect of the present disclosure, a cell determination apparatus is provided, the apparatus comprising: a processing module configured to determine at least one cell set corresponding to downlink control information for scheduling multiple cells; and for each first cell set in the at least one cell set, determining a reference cell in the first cell set, wherein, on the reference cell in the first cell set, the blind detection resources occupied by the downlink control information for scheduling multiple cells when scheduling cells in the first cell set are determined.

[0007] According to a fourth aspect of the present disclosure, a cell determination apparatus is provided, the apparatus comprising: a processing module configured to determine at least one cell set corresponding to downlink control information for scheduling multiple cells; and for each first cell set in the at least one cell set, determining a reference cell in the first cell set, wherein, on the reference cell in the first cell set, the blind detection resources occupied by the downlink control information for scheduling multiple cells when scheduling cells in the first cell set are determined.

[0008] According to a fifth aspect of the present disclosure, a cell determination system is provided, including a terminal and a network device, wherein the terminal is configured to implement the cell determination method performed by the terminal described above, and the network device is configured to implement the cell determination method performed by the network device described above.

[0009] According to a sixth aspect of the present disclosure, a communication device is provided, comprising: a processor; a memory for storing a computer program; wherein, when the computer program is executed by the processor, it implements the cell determination method executed by the terminal described above.

[0010] According to a seventh aspect of the present disclosure, a communication apparatus is provided, comprising: a processor; a memory for storing a computer program; wherein, when the computer program is executed by the processor, it implements the cell determination method executed by the network device described above.

[0011] According to an eighth aspect of the present disclosure, a computer-readable storage medium is provided for storing a computer program that, when executed by a processor, implements the cell determination method executed by a terminal as described above.

[0012] According to a ninth aspect of the present disclosure, a computer-readable storage medium is provided for storing a computer program that, when executed by a processor, implements the cell determination method performed by a network device as described above.

[0013] According to embodiments of this disclosure, a terminal can determine at least one set of cells corresponding to downlink control information used for scheduling multiple cells, and then determine a reference cell in each first set of cells. Subsequently, when scheduling cells in the first set of cells using downlink control information used for scheduling multiple cells, the blind detection resources occupied by the downlink control information used for scheduling multiple cells can be determined on the reference cell in the first set of cells.

[0014] Since the first cell set can include both scheduling cells and scheduled cells, the reference cells in the first cell set are not limited to scheduling cells but can include scheduled cells. This allows for the determination of blind detection resources on the scheduled cells used to schedule downlink control information for multiple cells. Consequently, this improves the terminal's blind detection efficiency and performance for downlink control information. Attached Figure Description

[0029] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0030] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0031] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination."

[0032] For the sake of brevity and ease of understanding, this document uses the terms "greater than" or "less than", "higher than" or "lower than" to describe size relationships. However, it will be understood by those skilled in the art that the term "greater than" also includes the meaning of "greater than or equal to", and "less than" also includes the meaning of "less than or equal to"; the term "higher than" also includes the meaning of "higher than or equal to", and "lower than" also includes the meaning of "lower than or equal to".

[0033] Figure 1 This is a schematic flowchart illustrating a cell determination method according to an embodiment of the present disclosure. The cell determination method shown in this embodiment can be executed by a terminal, which includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with network devices, which include, but are not limited to, network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0034] like Figure 1 As shown, the cell determination method may include the following steps:

[0035] In step S101, at least one set of cells corresponding to the downlink control information used for scheduling multiple cells is determined;

[0036] In step S102, for each first cell set in the at least one cell set, a reference cell in the first cell set is determined, wherein the blind detection resources occupied by the downlink control information used for scheduling multiple cells when scheduling cells in the first cell set are determined on the reference cell in the first cell set.

[0037] In one embodiment, when the at least one cell set contains multiple cell sets, the multiple cell sets may contain the same cells, or the multiple cell sets may not contain the same cells.

[0038] In one embodiment, downlink control information used to schedule multiple cells can be simply referred to as MC-DCI. MC-DCI is used to schedule multiple cells, specifically referring to data that can be used to schedule multiple cells, such as the PUSCH, PDSCH, etc. of one or more cells, thus realizing the scheduling of multiple cells through a single DCI. Here, MC stands for Multi-cell.

[0039] In one embodiment, the format of downlink control information used to schedule multiple cells can be the same as the format of legacy DCI (e.g., DCI format 0_0, DCI format 0_1, etc.), or a newly defined format, such as DCI format 0_3, DCI format 1_3, etc., can be used.

[0040] In one embodiment, downlink control information used to schedule multiple cells can be scrambled using Radio Network Temporary Identity (RNTI). For example, it can be scrambled using the Cell Radio Network Temporary Identity (C-RNTI) or a newly defined RNTI.

[0041] Since downlink control information used to schedule multiple cells can be used to schedule multiple cells, it contains more information compared to DCI used to schedule a single cell in legacy DCI, thus consuming more blind detection resources. Although the terminal can receive downlink control information used to schedule multiple cells (the scheduled cells) on the scheduling cell, if all the blind detection resources are determined based on the scheduling cell, it places an excessive burden on the scheduling cell, which is detrimental to ensuring good blind detection efficiency and performance.

[0042] According to embodiments of this disclosure, a terminal can determine at least one set of cells corresponding to downlink control information used for scheduling multiple cells, and then determine a reference cell in each first set of cells. Subsequently, when scheduling cells in the first set of cells using downlink control information used for scheduling multiple cells, the blind detection resources occupied by the downlink control information used for scheduling multiple cells can be determined on the reference cell in the first set of cells.

[0043] For example, at least one cell set includes cell sets such as first cell set #1 and first cell set #2. Reference cell Cell #1 in set #1 and reference cell Cell #2 in set #2 can be determined. Subsequently, when receiving downlink control information for scheduling multiple cells, if it is determined that the downlink control information is used to schedule multiple cells in set #1, then the blind detection resources occupied by the downlink control information for scheduling multiple cells can be determined on Cell #1; if it is determined that the downlink control information is used to schedule multiple cells in set #2, then the blind detection resources occupied by the downlink control information for scheduling multiple cells can be determined on Cell #2.

[0044] Since downlink control information used to schedule multiple cells can schedule multiple cells, such as multiple cells in a first cell set, this embodiment can determine a reference cell in the first cell set in this case. This reference cell can then be used to determine the blind detection resources occupied by the downlink control information used to schedule multiple cells when scheduling cells in the first cell set. Alternatively, a proportional coefficient can be introduced to determine the blind detection resources. This helps ensure the terminal's blind detection efficiency and performance for downlink control information and guarantees the fairness of blind detection resource allocation.

[0045] After determining the reference cell, the terminal can determine the configuration of the search space (SS) and / or control resource set (CORESET) corresponding to the downlink control information used to schedule multiple cells for the reference cell. Then, based on the configuration of the SS and / or CORESET, it can determine the blind detection resources occupied by the downlink control information used to schedule multiple cells. For example, it can determine the time domain resources and frequency domain resources of the downlink control information used to schedule multiple cells for blind detection. Then, on the slot or span of the downlink control information used to schedule multiple cells for blind detection, it can calculate the blind detection resources occupied by all DCIs (e.g., downlink control information used to schedule multiple cells and legacy DCIs), including the downlink control information used to schedule multiple cells.

[0046] It should be noted that the reference cell in the first set of cells can be one cell or multiple cells. Examples will be used to illustrate these two cases later.

[0047] In one embodiment, the blind detection resource includes at least one of the following:

[0048] Candidates for Physical Downlink Control Channel (PDCCH);

[0049] Control Channel Element (CCE).

[0050] Determining blind detection resources refers to determining the number of blind detection resources. For example, for the two types of blind detection resources mentioned above, it means determining the number of at least one blind detection resource among PDCCH candidates and CCEs within a certain time domain, such as a slot range or a PDCCH span. It should be noted that the blind detection resources determined in this disclosure are not limited to the aforementioned PDCCH candidates and CCEs. Other blind detection resources can also be determined as needed. For example, the determined blind detection resources may also include blind decoding (BD), where BD refers to the number of PDCCH candidates within a certain time period.

[0051] The following describes, through several embodiments, an exemplary method for determining reference cells in the first cell set. The method for determining reference cells in the first cell set can be based on predefined rules (e.g., protocol agreements) or on instructions from network devices; this disclosure does not limit this approach.

[0052] Figure 2 This is a schematic flowchart illustrating another cell determination method according to embodiments of the present disclosure. Figure 2 As shown, determining the reference cell in the first cell set includes:

[0053] In step S201, a reference cell in the first cell set is determined based on the cell identifier.

[0054] In one embodiment, when determining a reference cell in a first cell set, the cell ID of each cell in the first cell set can be determined first, and then a reference cell can be selected from the cells included in the first cell set based on the cell ID of each cell.

[0055] In one embodiment, determining the reference cell in the first cell set based on the cell identifier includes:

[0056] When the reference cell in the first cell set includes one cell, the cell with the largest cell identifier or the cell with the smallest cell identifier in the first cell set is determined as the reference cell in the first cell set; or...

[0057] When the reference cells in the first cell set include multiple cells, multiple cells in the first cell set are determined as reference cells in the first cell set in descending order of cell identifiers or in ascending order of cell identifiers.

[0058] In one embodiment, when the reference cell in the first cell set includes one cell, the reference cell in the first cell set is determined according to the cell identifier. This can be done by determining the cell with the largest cell identifier as the reference cell in the first cell set, or by determining the cell with the smallest cell identifier as the reference cell in the first cell set.

[0059] For example, the first cell set includes cells Cell#1 (Cell ID 1), Cell#2 (Cell ID 2), Cell#3 (Cell ID 3), and Cell#4 (Cell ID 4). When determining the cell with the largest cell ID as the reference cell in the first cell set, Cell#4 can be designated as the reference cell; similarly, when determining the cell with the smallest cell ID as the reference cell in the first cell set, Cell#1 can be designated as the reference cell.

[0060] In one embodiment, when the reference cells in the first cell set include multiple cells, the reference cells in the first cell set can be determined based on the cell identifiers. This can be done by determining multiple cells in the first cell set as reference cells in descending order of cell identifiers, or by determining multiple cells in the first cell set as reference cells in ascending order of cell identifiers.

[0061] For example, the first cell set includes cells Cell#1 (Cell ID 1), Cell#2 (Cell ID 2), Cell#3 (Cell ID 3), and Cell#4 (Cell ID 4), with 2 reference cells. When determining the cell with the largest cell ID as the reference cell in the first cell set, Cell#4 and Cell#3 can be selected as reference cells. Similarly, when determining the cell with the smallest cell ID as the reference cell in the first cell set, Cell#1 and Cell#2 can be selected as reference cells.

[0062] In one embodiment, the cells in the first cell set can be sorted according to a first order (e.g., determined according to predefined rules or network instructions), and then reference cells in the first cell set can be determined based on the sorting sequence number of the cells. For example, the first order includes, but is not limited to, cell identifiers in descending order, cell identifiers in ascending order, or blind detection resources corresponding to the DCIs configured in each cell in ascending order, or in descending order. The method for determining the blind detection resources corresponding to the DCIs configured in each cell will be described later.

[0063] Taking the first cell set containing four cells: Cell#1, Cell#2, Cell#3, and Cell#4, as an example, if the first order is sorted by Cell ID from largest to smallest, the sorted result would be Cell#4, Cell#3, Cell#2, and Cell#1. If we determine the cell with sorting number 3 as the reference cell for the first cell set, then Cell#2, being the cell with sorting number 3, can be designated as the reference cell for the first cell set.

[0064] Figure 3 This is a schematic flowchart illustrating a cell determination method according to an embodiment of the present disclosure. Figure 3 As shown, determining the reference cell in the first cell set includes:

[0065] In step S301, a reference cell in the first cell set is determined based on the blind detection resources occupied by the DCI configured in each cell of the first cell set.

[0066] In one embodiment, when determining a reference cell in a first cell set, the blind detection resources occupied by the DCI in each cell of the first cell set can be determined first, and then the reference cell in the first cell set can be determined based on the blind detection resources occupied by the DCI in each cell of the first cell set.

[0067] In one embodiment, determining the reference cell in the first cell set based on the blind detection resources allocated to DCI in each cell of the first cell set includes:

[0068] When the reference cell in the first cell set includes one cell, the cell in the first cell set with the minimum blind detection resources occupied by DCI is determined as the reference cell in the first cell set; or,

[0069] When the reference cells in the first cell set include multiple cells, multiple cells in the first cell set are determined as reference cells in the first cell set in ascending order of the blind detection resources occupied by DCI (DCI configured separately for each cell in the first cell set).

[0070] The blind detection resources occupied by the DCI configured in each cell can be the blind detection resources occupied by the legacy DCI configured in each cell, or the blind detection resources occupied by all the DCIs configured in each cell (e.g., including legacy DCIs and downlink control information used to schedule multiple cells).

[0071] In one embodiment, taking the blind detection resources occupied by the legacy DCI configured in each cell as an example, since the more blind detection resources the legacy DCI configured for a cell occupies, the fewer blind detection resources are needed for scheduling downlink control information for multiple cells, given a fixed amount of blind detection resources corresponding to the DCI configured in a cell. Therefore, when the reference cell in the first cell set includes one cell, the blind detection resources occupied by the legacy DCI configured in each cell of the first cell set can be determined first, and then the cell with the fewest blind detection resources occupied by the legacy DCI can be determined as the reference cell in the first cell set. This helps ensure the terminal's blind detection capability for downlink control information used to schedule multiple cells on the reference cell.

[0072] In one embodiment, taking the blind detection resources occupied by all DCIs configured in each cell as an example, the less blind detection resources occupied by all DCIs configured for a cell, the lower the blind detection complexity of the terminal will be. Therefore, when the reference cell in the first cell set includes one cell, the blind detection resources occupied by all DCIs configured in each cell of the first cell set can be determined first, and then the cell with the fewest blind detection resources occupied by all DCIs can be determined as the reference cell in the first cell set. This helps to reduce the blind detection complexity of the terminal on the reference cell.

[0073] For example, the first cell set includes Cell#1, Cell#2, Cell#3, and Cell#4. For these four cells, the blind detection resources occupied by the DCI configured for each cell can be determined. For example, the blind detection resources occupied by the DCI configured for Cell#1 are R1, those occupied by the DCI configured for Cell#2 are R2, those occupied by the DCI configured for Cell#3 are R3, and those occupied by the DCI configured for Cell#4 are R4. The order of these four blind detection resources from smallest to largest is R2, R3, R4, and R1. That is, the blind detection resources occupied by the DCI configured on Cell#2 are the smallest. Therefore, Cell#2 can be selected as the reference cell to determine the blind detection resources occupied by the downlink control information used to schedule multiple cells.

[0074] It should be noted that, in the embodiments of this disclosure, the blind detection resources occupied by the DCI configured for a specific cell are determined in ways including but not limited to the following two:

[0075] Method 1: Determine the search space configured for the cell, and sum all blind detection resources (e.g., PDCCH candidates) configured for DCI in the search space;

[0076] Method 2: Determine the search space configured for the cell, and sum the blind detection resources of the DCI corresponding to a specific time unit in the search space. The specific time unit can be defined by predefined rules or indicated by the network device, and can be one or more frames, and / or one or more subframes, and / or one or more time slots, and / or one or more symbols, and / or one or more PDCCH spans.

[0077] In one embodiment, taking the blind detection resources occupied by the legacy DCI configured in each cell as an example, since the more blind detection resources the legacy DCI occupies in a cell, the fewer blind detection resources are needed for scheduling downlink control information for multiple cells. Therefore, when the reference cells in the first cell set include multiple cells, the blind detection resources occupied by the legacy DCI configured in each cell of the first cell set can be determined first, and then multiple cells in the first cell set can be determined as reference cells in the first cell set in ascending order of the blind detection resources occupied by the legacy DCI. This helps ensure the terminal's blind detection capability for downlink control information used to schedule multiple cells on the reference cells.

[0078] In one embodiment, taking the blind detection resources occupied by all DCIs configured in each cell as an example, the less blind detection resources are occupied by all DCIs configured for a cell, the lower the blind detection complexity of the terminal will be. Therefore, when the reference cells in the first cell set include multiple cells, the blind detection resources occupied by all DCIs configured on each cell in the first cell set can be determined first. Then, multiple cells in the first cell set can be determined as reference cells in the first cell set in ascending order of the blind detection resources occupied by all DCIs. Accordingly, it is beneficial to ensure the terminal's blind detection capability for downlink control information used to schedule multiple cells on the reference cells.

[0079] For example, if the number of reference cells is 2, and the first cell set includes Cell#1, Cell#2, Cell#3, and Cell#4, the blind detection resources occupied by the DCI configured on each of these 4 cells can be determined. For example, the blind detection resources occupied by the DCI configured on Cell#1 are R1, those occupied by the DCI configured on Cell#2 are R2, those occupied by the DCI configured on Cell#3 are R3, and those occupied by the DCI configured on Cell#4 are R4. The order of these 4 blind detection resources from smallest to largest is R2, R3, R4, R1. That is, the blind detection resources occupied by the DCI configured on Cell#2 are the least, followed by the DCI configured on Cell#3, which has the least blind detection resources. Therefore, Cell#2 and Cell#3 can be selected as reference cells to determine the blind detection resources occupied by the downlink control information used to schedule multiple cells. The blind detection resources allocated to the DCI configured in the cell have been described above and will not be repeated here.

[0080] In one embodiment, the DCI includes at least one of the following:

[0081] Traditional DCI, also known as legacy DCI, includes DCI 0_0, DCI 0_1, DCI 1_0, DCI 1_1, DCI 2_0, DCI 2_1, etc.

[0082] All DCIs configured in the cell, including legacy DCIs and downlink control information used to schedule multiple cells.

[0083] Figure 4 This is a schematic flowchart illustrating yet another cell determination method according to embodiments of the present disclosure. Figure 4 As shown, determining the reference cell in the first cell set includes:

[0084] In step S401, the cell in the first cell set used to determine the downlink control information size budget for scheduling multiple cells is determined as the reference cell in the first cell set.

[0085] In one embodiment, when scheduling multiple cells in a first set of cells using downlink control information for scheduling multiple cells, the budget for the size (i.e., the number of bits) of the downlink control information used for scheduling multiple cells can be determined by at least one of the multiple cells. Specifically, at least one cell aligns the size of the DCI (including the downlink control information used for scheduling multiple cells) (which is a deductive alignment process for the terminal side).

[0086] Therefore, when selecting a reference cell, at least one cell used to determine the downlink control information size budget for scheduling multiple cells can be selected as the reference cell. In this way, the determination operations that need to be performed by the scheduled cells can be concentrated on one cell during the downlink control information scheduling process for multiple cells, which helps to simplify the configuration logic of the cells.

[0087] Figure 5 This is a schematic flowchart illustrating yet another cell determination method according to embodiments of the present disclosure. Figure 5 As shown, determining the reference cell in the first cell set includes:

[0088] In step S501, the cell in the first cell set that has configured the downlink control information corresponding to the search space for scheduling multiple cells is determined as the reference cell in the first cell set.

[0089] In one embodiment, when determining a reference cell in the first cell set, the search space corresponding to the downlink control information used for scheduling multiple cells within the first cell set can be determined first. Then, among the cells included in the first cell set, the cell configured with the search space corresponding to the downlink control information used for scheduling multiple cells can be determined as the reference cell. For example, if the search space is SS#1, that is, SS identified as 1, then the cell (which can be one or more cells) configured with SS identified as 1 can be determined as the reference cell.

[0090] It should be noted that the above-mentioned embodiments for determining reference cells in the first cell set can be implemented separately or combined as needed. For example, cells in the first cell set that are configured with downlink control information corresponding to the search space for scheduling multiple cells can be determined. If multiple cells are determined, the cell with the least blind detection resources occupied by the DCI configured in each of the multiple cells can be further determined as the reference cell.

[0091] Figure 6 This is a schematic flowchart illustrating yet another cell determination method according to embodiments of the present disclosure. Figure 6 As shown, when the reference cells in the first cell set include multiple cells, the blind detection resources used to determine the downlink control information for scheduling multiple cells in the reference cells of the first cell set for scheduling cells in the first cell set include:

[0092] In step S601, the blind detection resources allocated for scheduling downlink control information of multiple cells are determined for each of the reference cells in the first cell set.

[0093] In one embodiment, when the reference cell includes multiple cells, the blind detection resources used for scheduling downlink control information for the multiple cells can be determined separately in each of these cells.

[0094] Taking the first cell set containing Cell#1, Cell#2, Cell#3, and Cell#4 as an example.

[0095] If the reference cells are Cell#1 and Cell#2, then the blind detection resources occupied by downlink control information for scheduling multiple cells can be determined in Cell#1, and the blind detection resources occupied by downlink control information for scheduling multiple cells can be determined in Cell#2.

[0096] If all cells in the first cell set are determined as reference cells, then the blind detection resources occupied by downlink control information for scheduling multiple cells can be determined in Cell#1, Cell#2, Cell#3, and Cell#4.

[0097] In one embodiment, determining the blind detection resources allocated for scheduling multiple cells in each of the reference cells in the first cell set includes: determining the blind detection resources based on the determination results and quantization coefficients in each of the cells.

[0098] When the blind detection resources allocated for scheduling downlink control information across multiple cells are determined for each reference cell in the first cell set, the determination result for each cell (i.e., the determined blind detection resources) can be processed using quantization coefficients (e.g., by multiplying, dividing, adding, subtracting, taking the square root, or taking the logarithm based on the quantization coefficients) to obtain the final blind detection resources. For example, the determination result for a certain cell can be multiplied by a quantization coefficient to obtain the final determined blind detection resources for that cell.

[0099] In one embodiment, the quantization coefficient is determined based on the number of cells included in the reference cell (e.g., all or some cells in a first cell set). For example, the quantization coefficient can be 1 / K, where K is the number of cells included in the reference cell. This helps reduce the overall burden of blind detection resources required to determine downlink control information for scheduling multiple cells across multiple cells.

[0100] Taking the first cell set containing Cell#1, Cell#2, Cell#3, and Cell#4 as an example.

[0101] If the determined reference cells are Cell#1 and Cell#2, then the quantization coefficient is 1 / 2. The determination result A of the blind detection resources occupied by downlink control information used for scheduling multiple cells in Cell#1 can be multiplied by 1 / 2 to obtain A / 2, which is the blind detection resource occupied by downlink control information used for scheduling multiple cells in Cell#1. Similarly, the determination result B of the blind detection resources occupied by downlink control information used for scheduling multiple cells in Cell#2 can be multiplied by 1 / 2 to obtain B / 2, which is the blind detection resource occupied by downlink control information used for scheduling multiple cells in Cell#1.

[0102] If the determined reference cells are Cell#1, Cell#2, Cell#3, and Cell#4, then the quantization coefficient is 1 / 4. The result A of determining the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #1 can be multiplied by 1 / 4 to obtain A / 4 as the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #1; the result B of determining the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #2 can be multiplied by 1 / 4 to obtain B / 4 as the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #1; the result C of determining the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #3 can be multiplied by 1 / 4 to obtain C / 4 as the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #3; the result D of determining the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #4 can be multiplied by 1 / 4 to obtain D / 4 as the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #4.

[0103] In one embodiment, when the at least one cell set includes multiple cell sets and there are overlapping cells among the multiple cell sets, if the multiple first cell sets contain the same reference cell, the blind detection resources occupied by the downlink control information used to schedule multiple cells when scheduling cells in each of the multiple first cell sets are determined on the same reference cell.

[0104] In one embodiment, when at least one cell set is multiple cell sets, there may be overlapping cells (containing the same cells) between the multiple cell sets, or there may be no overlapping cells (not containing the same cells).

[0105] For example, consider two sets of neighborhoods.

[0106] If cell set set #1 is {Cell#1, Cell#2, Cell#3} and cell set set #2 is {Cell#1, Cell#4, Cell#5}, then there is an intersection {Cell#1} between set #1 and set #2, and the cell at the intersection is Cell#1.

[0107] If cell set set #1 is {Cell #1, Cell #2, Cell #3} and cell set set #3 is {Cell #4, Cell #5, Cell #6}, then there is no intersection between set #1 and set #3.

[0108] When multiple cell sets intersect, the same reference cell may be determined when identifying a reference cell for each first cell set within these sets. In this case, the blind detection resources used for scheduling downlink control information for multiple cells within this same reference cell can be determined. Therefore, the blind detection resources used for scheduling downlink control information for multiple cells within the same reference cell are the sum of the blind detection resources used for scheduling downlink control information for each first cell set.

[0109] For example, if the reference cell in set#1 is determined to be Cell#1, and the reference cell in set#2 is also determined to be Cell#1, then Cell#1 is the same reference cell. The blind detection resources used for scheduling downlink control information for multiple cells in set#1 are determined in Cell#1, such as A. The blind detection resources used for scheduling downlink control information for multiple cells in set#2 are determined in Cell#1, such as B. Therefore, the blind detection resources used for scheduling downlink control information for multiple cells in Cell#1 are the sum of A and B.

[0110] It should be noted that, in the embodiments of this disclosure, for a specific cell, the blind detection resources allocated to the downlink control information used for scheduling multiple cells are determined in ways including but not limited to the following two:

[0111] Method 1: Determine the search space configured for the cell, and sum all blind detection resources (e.g., PDCCH candidates) used to schedule downlink control information for multiple cells in the search space;

[0112] Method 2: Determine the search space configured for the cell, and sum the blind detection resources of downlink control information used to schedule multiple cells within a specific time unit in the search space. The specific time unit can be specified by predefined rules or indicated by network devices, and can be one or more frames, and / or one or more subframes, and / or one or more time slots, and / or one or more symbols.

[0113] In one embodiment, when the at least one cell set includes multiple cell sets and there are overlapping cells among the multiple cell sets, determining the reference cell in each first cell set in the at least one cell set includes:

[0114] For each of the multiple sets of first cells, a reference cell is determined in the first cell set, and the reference cell in each set of first cells is different.

[0115] In one embodiment, as described in the above embodiments, when at least one cell set includes multiple cell sets, and there are overlapping cells among the multiple cell sets, determining a reference cell for each first cell set among the multiple cell sets may result in the same reference cell being determined. Therefore, it is necessary to determine the blind detection resources occupied by each cell in the first cell set whose downlink control information scheduling for multiple cells intersects with this same reference cell. While this simplifies the configuration logic, the determination burden is significant for the same reference cell.

[0116] Therefore, considering the cell determination burden, in this embodiment, when at least one cell set includes multiple cell sets and there are overlapping cells among the multiple cell sets, different reference cells can be determined in each first cell set, thereby avoiding an excessive determination burden for a particular reference cell.

[0117] For example, for multiple cell sets:

[0118] First, the sorting method (also known as priority) of the cell set can be defined. For example, the cell set can be sorted from smallest to largest by its cell set identifier (id), or from largest to smallest by its cell set identifier, or from largest to smallest by the blind detection resources allocated to DCI for one or more cells in the cell set, or from smallest to largest by the blind detection resources allocated to DCI for one or more cells in the cell set. The following description primarily uses sorting the cell set from smallest to largest by its cell set identifier as an example.

[0119] Secondly, for the sorted set n (identified as n), determine the cells contained in set n, and determine the reference cells corresponding to the set m (which may be one or more cells) whose identifiers are less than n. Among them, when multiple cells in the MC DCI scheduling set m are determined on the reference cell, the blind detection resources occupied by the downlink control information used to schedule multiple cells can be determined.

[0120] Then, a second set of cells corresponding to cell set n is determined. If the reference cell in set m belongs to cell set n, the second set of cells is re-determined, and the second set of cells does not include the reference cell. That is, the second set of cells is equal to the range of all cells in set n excluding the reference cell belonging to set n (which may be the reference cell determined to be in set m).

[0121] Finally, among the cells included in the second cell set, a reference cell is determined (refer to the aforementioned embodiment). The determined reference cell is used to determine the blind detection resources occupied by the downlink control information used to schedule multiple cells when scheduling multiple cells in the scheduling set n.

[0122] Taking the determination of the reference cell based on the cell ID as an example, the above process is illustrated by the following pseudocode:

[0123] Determine the index γ(j) of the first cell set, wherein γ(j) gradually increases as j (j = 0, 1, 2, ...) increases;

[0124]

[0125] Taking three sets of first cells as an example, let's say set #1 contains {Cell#1, Cell#2, Cell#3}, set #2 contains {Cell#1, Cell#2, Cell#4}, and set #3 contains {Cell#3, Cell#4, Cell#5}. The cell sets are sorted in ascending order of their cell IDs as set #1, set #2, and set #3. For example, the reference cell can be determined by selecting the cell with the smallest ID from the first cell set.

[0126] First, determine the reference cell in set#1 (that is, the cell set corresponding to γ(1)). Take the cell with the smallest cellid in the first cell set as an example. For example, if the reference cell in set#1 is Cell#1, then Cell#1 belongs to set θ.

[0127] Then, the reference cell is determined in set#2 (that is, the cell set corresponding to γ(2)). Since Cell#1 in set#2 belongs to set θ, set#2 is redefined as the set of all remaining cells after excluding Cell#1. That is, set#2 is redefined as {Cell#2, Cell#4}. Cell#2 with the smallest cell identifier is selected in set#2. Since Cell#2 does not belong to set θ, Cell#2 is used as the reference cell in set#2. Set θ is redefined so that Cell#2 belongs to set θ.

[0128] Next, a reference cell is determined in set#3 (that is, the cell set corresponding to γ(3)). Considering that set#3 does not contain cells belonging to set θ, the cell corresponding to the smallest cell ID in set#3 is determined to be Cell#3. Since Cell#3 does not belong to set θ, Cell#3 can be used as a reference cell in set#3. The set θ is redefined so that Cell#2 belongs to set θ.

[0129] Therefore, a reference cell can be determined for each of the three first cell sets mentioned above, and it can be ensured that the reference cells in each first cell set are different.

[0130] The following examples illustrate how to determine at least one set of cells corresponding to downlink control information used for scheduling multiple cells.

[0131] In one embodiment, determining at least one set of cells corresponding to the downlink control information used for scheduling multiple cells includes:

[0132] Determine the configuration parameters of each cell in the plurality of cells (e.g., cells that can be scheduled by downlink control information used to schedule the plurality of cells), wherein the configuration parameters include, but are not limited to, set identifier, cell identifier, sequence number, and carrier indicator field (CIF);

[0133] Cells with the same configuration parameters are identified as belonging to a set of cells corresponding to downlink control information used to schedule multiple cells.

[0134] For example, taking four cells (Cell#1, Cell#2, Cell#3, and Cell#4) with configuration parameters including CIF, we can determine the CIF configured for each of these four cells (e.g., determined based on Radio Resource Control (RRC) signaling). For instance, 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, then we can determine that Cell#1 and Cell#2 have the same CIF, and Cell#3 and Cell#4 have the same CIF. Therefore, Cell#1 and Cell#2 are grouped into one cell set {Cell#1, Cell#2} for scheduling downlink control information of multiple cells, and Cell#3 and Cell#4 are grouped into another cell set {Cell#3, Cell#4} for scheduling downlink control information of multiple cells.

[0135] In one embodiment, determining at least one set of cells corresponding to the downlink control information used for scheduling multiple cells includes:

[0136] The system receives indication information sent by a network device in a first cell; determines multiple cell groups based on the indication information received in multiple first cells; determines the target cell group to which the first cell belongs in the multiple cell groups, and the set of cell groups to which the target cell group belongs; and determines the set of cells corresponding to the set of cell groups.

[0137] The terminal can receive indication information sent by network devices in multiple first cells. This indication information can indicate the association between the value of the Carrier Indication Field (CIF) corresponding to the first cell where the indication information is received and the scheduling cell identifier. The terminal can determine multiple cell groups based on the association corresponding to each first cell. Specifically, the association can be the association between the value of the Carrier Indication Field (CIF-InScheduingCell) within the scheduling cell and the scheduling cell identifier.

[0138] The terminal can determine whether the first cell is the cell scheduled by the downlink control information for scheduling multiple cells received in the second cell, based on the following method:

[0139] The process involves determining the ServingCellConfig of the Information Element (IE) in the RRC message, then determining the CrossCarrierSchedulingConfig within the ServingCellConfig, then determining the SchedulingCellInfo within the CrossCarrierSchedulingConfig, and finally, if the SchedulingCellInfo indicator value is "other", determining the SchedulingCellId and cif-InScheduingCell within the SchedulingCellInfo.

[0140] If the scheduling cell identifier configured in the RRC message is the same as the identifier of the second cell, and the value of cif-InScheduingCell configured in the RRC message is the same as the value of CIF in the downlink control information for scheduling multiple cells received in the second cell, it can be determined that the downlink control information for scheduling multiple cells received in the second cell is used to schedule the first cell.

[0141] The association relationship can define the correspondence between the values ​​of multiple carrier indication fields and multiple scheduling cell identifiers, and is not limited to one carrier indication field value being associated with one scheduling cell identifier. Therefore, when the network device sends downlink control information for scheduling multiple cells to the terminal according to the association relationship, it helps to improve the scheduling flexibility of the downlink control information for scheduling multiple cells on the first cell. For example, the network device can set the CIF value in the downlink control information for scheduling multiple cells according to the association relationship corresponding to the first cell that needs to be scheduled, thereby dynamically adjusting the multiple cells (cell groups) to be scheduled.

[0142] Figure 7 This is a schematic diagram illustrating another application scenario according to an embodiment of the present disclosure.

[0143] like Figure 7 As shown, taking three cells, Cell#0 (cell identifier 0), Cell#1 (cell identifier 1), and Cell#2 (cell identifier 2), as examples, the network device carries indication information through RRC messages.

[0144] The association carried by the network device in the RRC message sent from Cell#0 to the terminal is table1-0, the association carried in the RRC message sent from Cell#1 to the terminal is table1-1, and the association carried in the RRC message sent from Cell#2 to the terminal is table1-2.

[0145] The relationships contained in table1-0 are as follows: a value of 0 in the carrier indication field corresponds to a scheduling cell identifier of 2;

[0146] Table 1-1 contains the following relationships: a carrier indication field value of 1 corresponds to a scheduling cell identifier of 0, and a carrier indication field value of 2 corresponds to a scheduling cell identifier of 0. Therefore, when the CIF value in the downlink control information (Downlink Control Information) sent by the network device from the second cell (cell identifier 0) to the terminal for scheduling multiple cells is 1, it can schedule the first cell (e.g., Cell #1). Similarly, when the CIF value in the downlink control information sent by the second cell (cell identifier 0) to the terminal for scheduling multiple cells is 2, it can also schedule the first cell (e.g., Cell #1). The CIF value can range from 0 to 7, and can be adjusted as needed.

[0147] The relationships contained in Table 1-2 are as follows: a value of 1 in the carrier indication field corresponds to scheduling cell identifier 0, and a value of 3 in the carrier indication field also corresponds to scheduling cell identifier 0. Therefore, when the CIF value is 1 in the downlink control information (HSI) sent by the network device from the second cell (cell identifier 0) to the terminal for scheduling multiple cells, it can schedule the first cell (e.g., Cell #2). Similarly, when the CIF value is 3 in the HSI sent by the second cell (cell identifier 2) to the terminal for scheduling multiple cells, it can also schedule the first cell (e.g., Cell #2).

[0148] Since table1-0 contains the associations received in scheduling cell Cell#0, and the downlink control information received in the scheduling cell for scheduling multiple cells can be used for self-scheduling, that is, the downlink control information received in Cell#0 for scheduling multiple cells can be used to schedule Cell#0 itself, the associations corresponding to Cell#0 can include, in addition to the correspondences contained in table1-0, the following additional associations: a value of 0 in the carrier indication field corresponds to a scheduling cell identifier of 0, a value of 1 in the carrier indication field corresponds to a scheduling cell identifier of 0, a value of 2 in the carrier indication field corresponds to a scheduling cell identifier of 0, and a value of 3 in the carrier indication field corresponds to a scheduling cell identifier of 0.

[0149] It should be noted that, Figure 6 The blank spaces in the table shown can also be used to set the values ​​for the carrier indication field and the scheduling cell identifier, but these are not used in this example and are therefore not shown. Furthermore, the number of rows in the table is not limited to the four rows shown in the figure; the number of rows can be reduced or increased as needed.

[0150] Based on the above correlation, it can be determined that when the value of the carrier indication field is 0 (00), downlink control information used to schedule multiple cells can be scheduled for Cell#0; when the value of the carrier indication field is 1 (01), downlink control information used to schedule multiple cells can be scheduled for Cell#0, Cell#1, and Cell#2; when the value of the carrier indication field is 2 (10), downlink control information used to schedule multiple cells can be scheduled for Cell#0 and Cell#1; and when the value of the carrier indication field is 3 (11), downlink control information used to schedule multiple cells can be scheduled for Cell#0 and Cell#2. Accordingly, the relationship between the value of the carrier indication field and the scheduled cells that the terminal can determine is shown in Table 1 below:

[0151] CIF Community Group 00 {0} 01 {0,1,2} 10 {0,1} 11 {0,2}

[0152] Table 1

[0153] Here, a cell group can be a group of cells corresponding to the values ​​of each carrier indication field (or indicated by the values ​​of other fields) in the association relationship indicated by the indication information received by each first cell, as shown in Table 1. Multiple cell groups are {0}, {0,1,2}, {0,1}, and {0,2}. For ease of illustration, only the cell identifier is recorded in the set.

[0154] It is understood that each element in the tables shown in all embodiments of this disclosure exists independently. These elements are listed in the same table by way of example, but this does not mean that all elements in the table must exist simultaneously as shown in the table. The value of each element is independent of the values ​​of any other element in the table. Therefore, those skilled in the art will understand that the value of each element in the table is an independent embodiment.

[0155] Since cell groups also belong to cell group sets, and cell group sets can correspond to cell sets, after determining multiple cell groups, the terminal can further determine the target cell group to which the first cell belongs among the multiple cell groups, and then determine the cell group set to which the target cell group belongs, as well as the cell set corresponding to the cell group set. Thus, it can be determined that the first cell belongs to the determined cell set, which is the cell set corresponding to the downlink control information used to schedule multiple cells.

[0156] The communities contained in different community groups are different. For example, community group #1 contains community group #1 and community group #2, and community group #2 contains community group #3 and community group #4. Therefore, the communities contained in community group #1 and community group #2 are different from the communities contained in community group #3 and community group #4.

[0157] In one embodiment, determining the cell set corresponding to the cell group set includes: determining at least one cell group set based on the plurality of cell groups, wherein a first cell group in the first cell group set contains at least the same cells as a second cell group in the first cell group set; and determining that the cells contained in a cell group in one of the at least one cell group set constitute a cell set.

[0158] After determining multiple cell groups, the terminal can determine a set of cell groups based on these multiple cell groups. Cell groups containing the same cells can be grouped into the same set of cell groups. For example, if the first cell group and the second cell group contain the same cells, then the first cell group and the second cell group can be grouped into the same set of cell groups, for example, grouped into the first cell group set.

[0159] Then, we can identify neighborhood groups from other neighborhood groups that contain the same neighborhoods as any neighborhood group in the first neighborhood group set, and then add these identified neighborhood groups to the first neighborhood group set. This process is repeated to determine the first neighborhood group set. Finally, based on the method used to determine the first neighborhood group set, we can determine the other neighborhood group sets.

[0160] It should be noted that the first and second community groups in the same community group set are different. The first and second community groups do not refer to a specific community, but are any community group in a community group set.

[0161] For example, the following cell groups are used to determine the cell group set:

[0162] {0,1,2,3},{3},{5,6,7},{3,4,5,6},{8,9},{8};

[0163] First, we can consider any one of the cell groups. For example, if we first consider cell group {0,1,2,3}, we can determine that cell groups {3} and {3,4,5,6} contain the same cell Cell#3 as cell group {0,1,2,3}. Then, we can classify the three cell groups {3}, {3,4,5,6}, and {0,1,2,3} into the same cell group set, for example, called the first cell group set.

[0164] Then, we can determine which of the other cell groups contains the same cell as any cell group in the first cell group set. We can determine that cell group {5,6,7} contains the same cell Cell#5 and Cell#6 as cell group {3,4,5,6} in the first cell group set. Therefore, cell group {5,6,7} can also be assigned to the first cell group set.

[0165] Since cell groups {8,9} and {8} do not contain any cells in the same cell group as any cell group in the first cell group set, the first cell group set is now determined, and we can proceed to determine the second cell group set. For example, following the above method, we can determine that the second cell group set includes cell groups {8,9} and {8}.

[0166] For cell groups, for example, if the indication information received in Cell#1, Cell#2, Cell#3, and Cell#4 contains a cell set identifier of 1, and the indication information received in Cell#5, Cell#6, Cell#7, and Cell#8 contains a cell set identifier of 2, the terminal determines that Cell#1, Cell#2, Cell#3, and Cell#4 belong to the cell set with identifier 1 (cell set id = 1), and determines that Cell#5, Cell#6, Cell#7, and Cell#8 belong to the cell set with identifier 2 (cell set id = 2).

[0167] The downlink control information received by the terminal in the scheduling cell for scheduling multiple cells can be used to schedule multiple cells (Cell#1, Cell#2, Cell#3, Cell#4), or multiple cells (Cell#2, Cell#3). Another downlink control information received in the scheduling cell can be used to schedule multiple cells (Cell#5, Cell#6, Cell#7, Cell#8), or multiple cells (Cell#6, Cell#7). Therefore, four cell groups can be identified: {1,2,3,4}, {2,3}, {5,6,7,8}, and {6,7}, as well as two cell group sets: {{1,2,3,4}, {2,3}}, and {{5,6,7,8}, {6,7}}. The different cell group sets can be determined by the cells scheduled by the downlink control information sent by different cells.

[0168] In one embodiment, the method for determining the cell set corresponding to the cell group set may be to determine the cells contained in the cell group within the cell group set, and then use the determined set of cells as the cell set corresponding to the cell group set.

[0169] Figure 8 This is a schematic diagram illustrating another application scenario according to an embodiment of the present disclosure.

[0170] like Figure 8 As shown, taking the first cell group set and the second cell group set determined in the aforementioned embodiment as an example, 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}}.

[0171] It can be determined that the cell group in the first cell group set contains Cell#0, Cell#1, Cell#2, Cell#3, Cell#4, Cell#5, Cell#6, and Cell#7. Therefore, the cell set formed by these cells is {0,1,2,3,4,5,6,7}, which is the cell set corresponding to the first cell group set. Similarly, the cell set corresponding to the second cell group set is {8,9}. Therefore, at least one cell set corresponding to the downlink control information used for scheduling multiple cells includes cell set {0,1,2,3,4,5,6,7} and cell set {8,9}.

[0172] In one embodiment, determining at least one cell set corresponding to downlink control information for scheduling multiple cells includes: receiving indication information sent by a network device in a first cell; determining multiple cell groups based on the indication information received in multiple first cells; and determining the cell group as a cell set.

[0173] The method for determining multiple cell groups is similar to that in the previous embodiments, and will not be repeated here. The difference between this embodiment and the previous embodiments is that the cell group is directly determined as a set of cells, without determining the set of cells to which the cell group belongs. For example, after determining Table 1 according to the instruction information, the multiple cell groups {0}, {0,1,2}, {0,1}, and {0,2} in Table 1 can be respectively regarded as sets of cells. That is, at least one set of cells corresponding to the downlink control information used to schedule multiple cells includes the four sets {0}, {0,1,2}, {0,1}, and {0,2}.

[0174] Figure 9 This is a schematic flowchart illustrating a cell determination method according to an embodiment of the present disclosure. The cell determination method shown in this embodiment can be executed by a network device that can communicate with a terminal. The network device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.

[0175] like Figure 9 As shown, the cell determination method may include the following steps:

[0176] In step S901, at least one set of cells corresponding to the downlink control information used for scheduling multiple cells is determined;

[0177] In step S902, for each first cell set in the at least one cell set, a reference cell in the first cell set is determined, wherein the blind detection resources occupied by the downlink control information used for scheduling multiple cells when scheduling cells in the first cell set are determined on the reference cell in the first cell set.

[0178] In one embodiment, when the at least one cell set contains multiple cell sets, the multiple cell sets may contain the same cells, or the multiple cell sets may not contain the same cells.

[0179] In one embodiment, downlink control information used to schedule multiple cells can be simply referred to as MC-DCI. MC-DCI is used to schedule multiple cells, specifically referring to data that can be used to schedule multiple cells, such as the PUSCH, PDSCH, etc. of one or more cells, thus realizing the scheduling of multiple cells through a single DCI. Here, MC stands for Multi-cell.

[0180] In one embodiment, the format of downlink control information used to schedule multiple cells can be the same as the format of legacy DCI (e.g., DCI format 0_0, DCI format 0_1, etc.), or a newly defined format, such as DCI format 0_3, DCI format 1_3, etc., can be used.

[0181] In one embodiment, downlink control information used to schedule multiple cells can be scrambled using Radio Network Temporary Identity (RNTI). For example, it can be scrambled using the Cell Radio Network Temporary Identity (C-RNTI) or a newly defined RNTI.

[0182] Since downlink control information used to schedule multiple cells can be used to schedule multiple cells, it contains more information compared to DCI used to schedule a single cell in legacy DCI, thus consuming more blind detection resources. Although the terminal can use downlink control information for scheduling multiple cells (the scheduled cells) on the scheduling cell, if all the blind detection resources are determined based on the scheduling cell, it places an excessive burden on the scheduling cell, which is detrimental to ensuring good blind detection efficiency and performance.

[0183] According to embodiments of this disclosure, after determining at least one set of cells corresponding to downlink control information used for scheduling multiple cells, the network device can determine a reference cell in each first set of cells. Subsequently, when scheduling cells in the first set of cells using downlink control information used for scheduling multiple cells, the blind detection resources occupied by the downlink control information used for scheduling multiple cells can be determined on the reference cell in the first set of cells.

[0184] For example, at least one cell set includes cell sets such as first cell set #1 and first cell set #2. Reference cell Cell #1 in set #1 and reference cell Cell #2 in set #2 can be determined. Subsequently, when receiving downlink control information for scheduling multiple cells, if it is determined that the downlink control information is used to schedule multiple cells in set #1, then the blind detection resources occupied by the downlink control information for scheduling multiple cells can be determined on Cell #1; if it is determined that the downlink control information is used to schedule multiple cells in set #2, then the blind detection resources occupied by the downlink control information for scheduling multiple cells can be determined on Cell #2.

[0185] Since downlink control information used to schedule multiple cells can schedule multiple cells, such as multiple cells in a first cell set, this embodiment can determine a reference cell in the first cell set in this case. This reference cell can then be used to determine the blind detection resources occupied by the downlink control information used to schedule multiple cells when scheduling cells in the first cell set. This helps ensure the blind detection efficiency and performance of subsequent terminals for downlink control information.

[0186] After determining the reference cell in the first cell set, the terminal can determine the blind detection resources occupied by the downlink control information used to schedule multiple cells when scheduling cells in the first cell set on the reference cell in the first cell set. When the determined blind detection resources exceed the blind detection capability, a portion of the blind detection resources corresponding to the configured DCI can be dropped, and no blind detection of DCI will be performed on the dropped portion of blind detection resources.

[0187] The network device determines a reference cell in the first cell set, and determines the blind detection resources occupied when scheduling the downlink control information for scheduling multiple cells in the first cell set on the reference cell in the first cell set. This can further determine the blind detection resources that subsequent terminals may discard, which is beneficial to improving the flexibility and effectiveness of scheduling.

[0188] After determining the reference cell, the network equipment can determine the configuration of the search space (SS) and / or the control resource set (CORESET) corresponding to the downlink control information used for scheduling multiple cells, which is configured for the reference cell. Then, based on the configuration of the SS and / or the CORESET, the blind detection resources occupied by the downlink control information used for scheduling multiple cells can be determined. For example, the time domain resources and frequency domain resources of the downlink control information used for scheduling multiple cells can be determined. Then, on the slot or span of the downlink control information used for scheduling multiple cells, the blind detection resources occupied by all DCIs (e.g., downlink control information used for scheduling multiple cells and legacy DCIs) including the downlink control information used for scheduling multiple cells can be calculated.

[0189] It should be noted that the reference cell in the first set of cells can be one cell or multiple cells. Examples will be used to illustrate these two cases later.

[0190] In one embodiment, the blind detection resource includes at least one of the following:

[0191] Candidate Physical Downlink Control Channel (PDCCH) candidates;

[0192] Control Channel Unit (CCE)

[0193] Determining blind detection resources refers to determining the number of blind detection resources. For example, for the two types of blind detection resources mentioned above, it refers to determining the number of at least one blind detection resource among PDCCH candidates and CCEs within a certain time domain, such as a slot range or a PDCCH span. It should be noted that the blind detection resources determined in this disclosure are not limited to the aforementioned PDCCH candidates and CCEs. Other blind detection resources can also be determined as needed. For example, the determined blind detection resources may also include blind detection BDs, where BDs refer to the number of PDCCH candidates within a certain time period.

[0194] The following describes, through several embodiments, an exemplary method for determining reference cells in the first cell set. The method for determining reference cells in the first cell set can be based on predefined rules (e.g., protocol agreements) or on instructions from network devices; this disclosure does not limit this approach.

[0195] In one embodiment, determining a reference cell in the first cell set includes: determining a reference cell in the first cell set based on a cell identifier.

[0196] In one embodiment, when determining a reference cell in a first cell set, the cell ID of each cell in the first cell set can be determined first, and then a reference cell can be selected from the cells included in the first cell set based on the cell ID of each cell.

[0197] In one embodiment, determining the 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 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 cell in the first cell set includes multiple cells, determining multiple cells in the first cell set in descending order of cell identifier or in ascending order of cell identifier as the reference cell in the first cell set.

[0198] In one embodiment, when the reference cell in the first cell set includes one cell, the reference cell in the first cell set is determined according to the cell identifier. This can be done by determining the cell with the largest cell identifier as the reference cell in the first cell set, or by determining the cell with the smallest cell identifier as the reference cell in the first cell set.

[0199] For example, the first cell set includes cells Cell#1 (Cell ID 1), Cell#2 (Cell ID 2), Cell#3 (Cell ID 3), and Cell#4 (Cell ID 4). When determining the cell with the largest cell ID as the reference cell in the first cell set, Cell#4 can be designated as the reference cell; similarly, when determining the cell with the smallest cell ID as the reference cell in the first cell set, Cell#1 can be designated as the reference cell.

[0200] In one embodiment, when the reference cells in the first cell set include multiple cells, the reference cells in the first cell set can be determined based on the cell identifiers. This can be done by determining multiple cells in the first cell set as reference cells in descending order of cell identifiers, or by determining multiple cells in the first cell set as reference cells in ascending order of cell identifiers.

[0201] For example, the first cell set includes cells Cell#1 (Cell ID 1), Cell#2 (Cell ID 2), Cell#3 (Cell ID 3), and Cell#4 (Cell ID 4), with 2 reference cells. When determining the cell with the largest cell ID as the reference cell in the first cell set, Cell#4 and Cell#3 can be selected as reference cells. Similarly, when determining the cell with the smallest cell ID as the reference cell in the first cell set, Cell#1 and Cell#2 can be selected as reference cells.

[0202] In one embodiment, cells in the first cell set can be sorted according to a first order (e.g., determined according to predefined rules or network instructions), and then reference cells in the first cell set can be determined based on the sorting sequence number of the cells. For example, the first order includes, but is not limited to, cell identifiers from largest to smallest and cell identifiers from smallest to largest.

[0203] Taking the first cell set containing four cells: Cell#1, Cell#2, Cell#3, and Cell#4, as an example, if the first order is sorted by Cell ID from largest to smallest, the sorted result would be Cell#4, Cell#3, Cell#2, and Cell#1. If we determine the cell with sorting number 3 as the reference cell for the first cell set, then Cell#2, being the cell with sorting number 3, can be designated as the reference cell for the first cell set.

[0204] In one embodiment, determining the reference cell in the first cell set includes: determining the reference cell in the first cell set based on the blind detection resources occupied by the DCI configured in each cell of the first cell set.

[0205] In one embodiment, when determining a reference cell in a first cell set, the blind detection resources occupied by the DCI in each cell of the first cell set can be determined first, and then the reference cell in the first cell set can be determined based on the blind detection resources occupied by the DCI in each cell of the first cell set.

[0206] In one embodiment, determining the reference cell in the first cell set based on the blind detection resources occupied by the DCI configured in each cell of the first cell set includes: when the reference cell in the first cell set includes one cell, determining the cell in the first cell set with the minimum blind detection resources occupied by the DCI 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 as reference cells in the first cell set in ascending order of the blind detection resources occupied by the DCI (which is configured separately for each cell in the first cell set).

[0207] The blind detection resources occupied by the DCI configured in each cell can be the blind detection resources occupied by the legacy DCI configured in each cell, or the blind detection resources occupied by all the DCIs configured in each cell (e.g., including legacy DCIs and downlink control information used to schedule multiple cells).

[0208] In one embodiment, taking the blind detection resources occupied by the legacy DCI configured in each cell as an example, since the more blind detection resources the legacy DCI configured for a cell occupies, the fewer blind detection resources are needed for scheduling downlink control information for multiple cells, given a fixed amount of blind detection resources corresponding to the DCI configured in a cell. Therefore, when the reference cell in the first cell set includes one cell, the blind detection resources occupied by the legacy DCI configured in each cell of the first cell set can be determined first, and then the cell with the fewest blind detection resources occupied by the legacy DCI can be determined as the reference cell in the first cell set. This helps ensure the terminal's blind detection capability for downlink control information used to schedule multiple cells on the reference cell.

[0209] In one embodiment, taking the blind detection resources occupied by all DCIs configured in each cell as an example, the less blind detection resources occupied by all DCIs configured for a cell, the lower the blind detection complexity of the terminal will be. Therefore, when the reference cell in the first cell set includes one cell, the blind detection resources occupied by all DCIs configured in each cell of the first cell set can be determined first, and then the cell with the fewest blind detection resources occupied by all DCIs can be determined as the reference cell in the first cell set. This helps to reduce the blind detection complexity of the terminal on the reference cell.

[0210] For example, the first cell set includes Cell#1, Cell#2, Cell#3, and Cell#4. For these four cells, the blind detection resources occupied by the DCI configured for each cell can be determined. For example, the blind detection resources occupied by the DCI configured for Cell#1 are R1, those occupied by the DCI configured for Cell#2 are R2, those occupied by the DCI configured for Cell#3 are R3, and those occupied by the DCI configured for Cell#4 are R4. The order of these four blind detection resources from smallest to largest is R2, R3, R4, and R1. That is, the blind detection resources occupied by the DCI configured on Cell#2 are the smallest. Therefore, Cell#2 can be selected as the reference cell to determine the blind detection resources occupied by the downlink control information used to schedule multiple cells.

[0211] It should be noted that, in the embodiments of this disclosure, the blind detection resources occupied by the DCI configured for a specific cell are determined in ways including but not limited to the following two:

[0212] Method 1: Determine the search space configured for the cell, and sum all blind detection resources (e.g., PDCCH candidates) in the search space for DCI;

[0213] Method 2: Determine the search space configured for the cell, and sum the blind detection resources of the DCI corresponding to a specific time unit in the search space. The specific time unit can be defined by predefined rules or indicated by the network device, and can be one or more frames, and / or one or more subframes, and / or one or more time slots, and / or one or more symbols, and / or one or more PDCCH spans.

[0214] In one embodiment, taking the blind detection resources occupied by the legacy DCI configured in each cell as an example, since the more blind detection resources the legacy DCI occupies in a cell, the fewer blind detection resources are needed for scheduling downlink control information for multiple cells. Therefore, when the reference cells in the first cell set include multiple cells, the blind detection resources occupied by the legacy DCI configured in each cell of the first cell set can be determined first, and then multiple cells in the first cell set can be determined as reference cells in the first cell set in ascending order of the blind detection resources occupied by the legacy DCI. This helps ensure the terminal's blind detection capability for downlink control information used to schedule multiple cells on the reference cells.

[0215] In one embodiment, taking the blind detection resources occupied by all DCIs configured in each cell as an example, the less blind detection resources are occupied by all DCIs configured for a cell, the lower the blind detection complexity of the terminal will be. Therefore, when the reference cells in the first cell set include multiple cells, the blind detection resources occupied by all DCIs configured on each cell in the first cell set can be determined first. Then, multiple cells in the first cell set can be determined as reference cells in the first cell set in ascending order of the blind detection resources occupied by all DCIs. Accordingly, it is beneficial to ensure the terminal's blind detection capability for downlink control information used to schedule multiple cells on the reference cells.

[0216] For example, if the number of reference cells is 2, and the first cell set includes Cell#1, Cell#2, Cell#3, and Cell#4, the blind detection resources occupied by the DCI configured on each of these 4 cells can be determined. For example, the blind detection resources occupied by the DCI configured on Cell#1 are R1, those occupied by the DCI configured on Cell#2 are R2, those occupied by the DCI configured on Cell#3 are R3, and those occupied by the DCI configured on Cell#4 are R4. The order of these 4 blind detection resources from smallest to largest is R2, R3, R4, R1. That is, the blind detection resources occupied by the DCI configured on Cell#2 are the least, followed by the DCI configured on Cell#3, which has the least blind detection resources. Therefore, Cell#2 and Cell#3 can be selected as reference cells to determine the blind detection resources occupied by the downlink control information used to schedule multiple cells. The blind detection resources allocated to the DCI configured in the cell have been described above and will not be repeated here.

[0217] In one embodiment, the DCI includes at least one of the following: conventional DCI; all DCIs configured in the cell.

[0218] In one embodiment, determining the reference cell in the first cell set includes: determining the cell in the first cell set used to determine the downlink control information size budget for scheduling multiple cells as the reference cell in the first cell set.

[0219] In one embodiment, when scheduling multiple cells in a first set of cells using downlink control information for scheduling multiple cells, the downlink control information size (i.e., the number of bits) budget for scheduling multiple cells can be determined by at least one of the multiple cells, specifically by aligning the size of the DCI (including the downlink control information for scheduling multiple cells).

[0220] Therefore, when selecting a reference cell, at least one cell used to determine the downlink control information size budget for scheduling multiple cells can be selected as the reference cell. In this way, the determination operations that need to be performed by the scheduled cells can be concentrated on one cell during the downlink control information scheduling process for multiple cells, which helps to simplify the configuration logic of the cells.

[0221] In one embodiment, a cell in the first cell set that has configured the search space corresponding to the downlink control information for scheduling multiple cells is identified as a reference cell in the first cell set.

[0222] In one embodiment, when determining a reference cell in the first cell set, the search space corresponding to the downlink control information used for scheduling multiple cells within the first cell set can be determined first. Then, among the cells included in the first cell set, the cell configured with the search space corresponding to the downlink control information used for scheduling multiple cells can be determined as the reference cell. For example, if the search space is SS#1, that is, SS identified as 1, then the cell (which can be one or more cells) configured with SS identified as 1 can be determined as the reference cell.

[0223] It should be noted that the above-mentioned embodiments for determining reference cells in the first cell set can be implemented separately or combined as needed. For example, cells in the first cell set that are configured with downlink control information corresponding to the search space for scheduling multiple cells can be determined. If multiple cells are determined, the cell with the least blind detection resources occupied by the DCI configured in each of the multiple cells can be further determined as the reference cell.

[0224] In one embodiment, when the reference cells in the first cell set include multiple cells, determining the blind detection resources occupied by the downlink control information used for scheduling multiple cells in the reference cells of the first cell set when scheduling cells in the first cell set includes: determining the blind detection resources occupied by the configured downlink control information used for scheduling multiple cells in each of the reference cells in the first cell set.

[0225] In one embodiment, when the reference cell includes multiple cells, the blind detection resources used for scheduling downlink control information for the multiple cells can be determined separately in each of these cells.

[0226] Taking the first cell set containing Cell#1, Cell#2, Cell#3, and Cell#4 as an example.

[0227] If the reference cells are Cell#1 and Cell#2, then the blind detection resources occupied by downlink control information for scheduling multiple cells can be determined in Cell#1, and the blind detection resources occupied by downlink control information for scheduling multiple cells can be determined in Cell#2.

[0228] If all cells in the first cell set are determined as reference cells, then the blind detection resources occupied by downlink control information for scheduling multiple cells can be determined in Cell#1, Cell#2, Cell#3, and Cell#4.

[0229] In one embodiment, determining the blind detection resources allocated for scheduling multiple cells in each of the reference cells in the first cell set includes: determining the blind detection resources based on the determination results and quantization coefficients in each of the cells.

[0230] When the blind detection resources allocated for scheduling downlink control information across multiple cells are determined for each reference cell in the first cell set, the determination result for each cell (i.e., the determined blind detection resources) can be processed using quantization coefficients (e.g., by multiplying, dividing, adding, subtracting, taking the square root, or taking the logarithm of the determination result based on the quantization coefficients) to obtain the final blind detection resources. For example, the determination result for a certain cell can be multiplied by a quantization coefficient to obtain the final determined blind detection resources for that cell.

[0231] In one embodiment, the quantization coefficient is determined based on the number of cells included in the reference cell (e.g., all or some cells in a first cell set). For example, the quantization coefficient can be one-K times the number of cells in the reference cell, where K is the number of cells in the reference cell. This helps reduce the overall burden of blind detection resources required to determine downlink control information for scheduling multiple cells across multiple cells.

[0232] Taking the first cell set containing Cell#1, Cell#2, Cell#3, and Cell#4 as an example.

[0233] If the determined reference cells are Cell#1 and Cell#2, then the quantization coefficient is 1 / 2. The determination result A of the blind detection resources occupied by downlink control information used for scheduling multiple cells in Cell#1 can be multiplied by 1 / 2 to obtain A / 2, which is the blind detection resource occupied by downlink control information used for scheduling multiple cells in Cell#1. Similarly, the determination result B of the blind detection resources occupied by downlink control information used for scheduling multiple cells in Cell#2 can be multiplied by 1 / 2 to obtain B / 2, which is the blind detection resource occupied by downlink control information used for scheduling multiple cells in Cell#1.

[0234] If the determined reference cells are Cell#1, Cell#2, Cell#3, and Cell#4, then the quantization coefficient is 1 / 4. The result A of determining the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #1 can be multiplied by 1 / 4 to obtain A / 4 as the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #1; the result B of determining the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #2 can be multiplied by 1 / 4 to obtain B / 4 as the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #1; the result C of determining the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #3 can be multiplied by 1 / 4 to obtain C / 4 as the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #3; the result D of determining the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #4 can be multiplied by 1 / 4 to obtain D / 4 as the blind detection resources occupied by downlink control information for scheduling multiple cells in Cell #4.

[0235] In one embodiment, when the at least one cell set includes multiple cell sets and there are overlapping cells among the multiple cell sets, if the multiple first cell sets contain the same reference cell, the blind detection resources occupied by the downlink control information used to schedule multiple cells when scheduling cells in each of the multiple first cell sets are determined on the same reference cell.

[0236] In one embodiment, when at least one cell set is multiple cell sets, there may be overlapping cells (containing the same cells) between the multiple cell sets, or there may be no overlapping cells (not containing the same cells).

[0237] For example, consider two sets of neighborhoods.

[0238] If cell set set #1 is {Cell#1, Cell#2, Cell#3} and cell set set #2 is {Cell#1, Cell#4, Cell#5}, then there is an intersection {Cell#1} between set #1 and set #2, and the cell at the intersection is Cell#1.

[0239] If cell set set #1 is {Cell #1, Cell #2, Cell #3} and cell set set #3 is {Cell #4, Cell #5, Cell #6}, then there is no intersection between set #1 and set #3.

[0240] When multiple cell sets intersect, the same reference cell may be determined when identifying a reference cell for each first cell set within these sets. In this case, the blind detection resources used for scheduling downlink control information for multiple cells within this same reference cell can be determined. Therefore, the blind detection resources used for scheduling downlink control information for multiple cells within the same reference cell are the sum of the blind detection resources used for scheduling downlink control information for each first cell set.

[0241] For example, if the reference cell in set#1 is determined to be Cell#1, and the reference cell in set#2 is also determined to be Cell#1, then Cell#1 is the same reference cell. The blind detection resources used for scheduling downlink control information for multiple cells in set#1 are determined in Cell#1, such as A. The blind detection resources used for scheduling downlink control information for multiple cells in set#2 are determined in Cell#1, such as B. Therefore, the blind detection resources used for scheduling downlink control information for multiple cells in Cell#1 are the sum of A and B.

[0242] It should be noted that, in the embodiments of this disclosure, for a specific cell, the blind detection resources allocated to the downlink control information used for scheduling multiple cells are determined in ways including but not limited to the following two:

[0243] Method 1: Determine the search space configured for the cell, and sum all blind detection resources (e.g., PDCCH candidates) used to schedule downlink control information for multiple cells in the search space;

[0244] Method 2: Determine the search space configured for the cell, and sum the blind detection resources of downlink control information used to schedule multiple cells within a specific time unit in the search space. The specific time unit can be specified by predefined rules or indicated by network devices, and can be one or more frames, and / or one or more subframes, and / or one or more time slots, and / or one or more symbols.

[0245] In one embodiment, when the at least one cell set includes multiple cell sets and there are overlapping cells among the multiple cell sets, determining a reference cell in each of the first cell sets in the at least one cell set includes: determining a reference cell in each of the multiple first cell sets, and the reference cell in each first cell set is different.

[0246] In one embodiment, as described in the above embodiments, when at least one cell set includes multiple cell sets, and there are overlapping cells among the multiple cell sets, determining a reference cell for each first cell set among the multiple cell sets may result in the same reference cell being determined. Therefore, it is necessary to determine the blind detection resources occupied by each cell in the first cell set whose downlink control information scheduling for multiple cells intersects with this same reference cell. While this simplifies the configuration logic, the determination burden is significant for the same reference cell.

[0247] Therefore, considering the cell determination burden, in this embodiment, when at least one cell set includes multiple cell sets and there are overlapping cells among the multiple cell sets, different reference cells can be determined in each first cell set, thereby avoiding an excessive determination burden for a particular reference cell.

[0248] For example, for multiple cell sets:

[0249] First, the sorting method (also known as priority) of the cell set can be defined. For example, the cell set can be sorted from smallest to largest by its cell set identifier (id), or from largest to smallest by its cell set identifier, or from largest to smallest by the blind detection resources allocated to DCI for one or more cells in the cell set, or from smallest to largest by the blind detection resources allocated to DCI for one or more cells in the cell set. The following description primarily uses sorting the cell set from smallest to largest by its cell set identifier as an example.

[0250] Secondly, for the sorted set n (identified as n), determine the cells contained in set n, and determine the reference cells corresponding to the set m (which may be one or more cells) whose identifiers are less than n. Among them, when multiple cells in the MC DCI scheduling set m are determined on the reference cell, the blind detection resources occupied by the downlink control information used to schedule multiple cells can be determined.

[0251] Then, a second set of cells corresponding to cell set n is determined. If the reference cell in set m belongs to cell set n, the second set of cells is re-determined, and the second set of cells does not include the reference cell. That is, the second set of cells is equal to the range of all cells in set n excluding the reference cell belonging to set n (which may be the reference cell determined to be in set m).

[0252] Finally, among the cells included in the second cell set, a reference cell is determined (refer to the aforementioned embodiment). The determined reference cell is used to determine the blind detection resources occupied by the downlink control information used to schedule multiple cells when scheduling multiple cells in the scheduling set n.

[0253] Taking the determination of the reference cell based on the cell ID as an example, the above process is illustrated by the following pseudocode:

[0254] Determine the index γ(j) of the first cell set, wherein γ(j) gradually increases as j (j = 0, 1, 2, ...) increases;

[0255]

[0256] Taking three sets of first cells as an example, let's say set #1 contains {Cell#1, Cell#2, Cell#3}, set #2 contains {Cell#1, Cell#2, Cell#4}, and set #3 contains {Cell#3, Cell#4, Cell#5}. The cell sets are sorted in ascending order of their cell IDs as set #1, set #2, and set #3. For example, the reference cell can be determined by selecting the cell with the smallest ID from the first cell set.

[0257] First, determine the reference cell in set#1 (that is, the cell set corresponding to γ(1)). Take the cell with the smallest cellid in the first cell set as an example. For example, if the reference cell in set#1 is Cell#1, then Cell#1 belongs to set θ.

[0258] Then, the reference cell is determined in set#2 (that is, the cell set corresponding to γ(2)). Since Cell#1 in set#2 belongs to set θ, set#2 is redefined as the set of all remaining cells after excluding Cell#1. That is, set#2 is redefined as {Cell#2, Cell#4}. Cell#2 with the smallest cell identifier is selected in set#2. Since Cell#2 does not belong to set θ, Cell#2 is used as the reference cell in set#2. Set θ is redefined so that Cell#2 belongs to set θ.

[0259] Next, a reference cell is determined in set#3 (that is, the cell set corresponding to γ(3)). Considering that set#3 does not contain cells belonging to set θ, the cell corresponding to the smallest cell ID in set#3 is determined to be Cell#3. Since Cell#3 does not belong to set θ, Cell#3 can be used as a reference cell in set#3. The set θ is redefined so that Cell#2 belongs to set θ.

[0260] Therefore, a reference cell can be determined for each of the three first cell sets mentioned above, and it can be ensured that the reference cells in each first cell set are different.

[0261] The following examples illustrate how to determine at least one set of cells corresponding to downlink control information used for scheduling multiple cells.

[0262] In one embodiment, determining at least one set of cells corresponding to the downlink control information used for scheduling multiple cells includes:

[0263] Determine the configuration parameters for each cell in a plurality of cells (e.g., cells that can be scheduled by downlink control information used to schedule multiple cells);

[0264] Cells with the same configuration parameters are identified as belonging to a set of cells corresponding to downlink control information used to schedule multiple cells.

[0265] For example, taking four cells (Cell#1, Cell#2, Cell#3, and Cell#4) with configuration parameters including the Carrier Indicator Field (CIF), the CIF configured for each of these four cells can be determined (e.g., based on Radio Resource Control (RRC) signaling). For instance, if the CIF configured for Cell#1 is 01, for Cell#2 is 01, for Cell#3 is 02, and for Cell#4 is 02, then it can be determined that Cell#1 and Cell#2 have the same CIF, and Cell#3 and Cell#4 have the same CIF. Therefore, Cell#1 and Cell#2 are grouped into one cell set {Cell#1, Cell#2} used for scheduling downlink control information for multiple cells, and Cell#3 and Cell#4 are grouped into another cell set {Cell#3, Cell#4} used for scheduling downlink control information for multiple cells.

[0266] In one embodiment, determining at least one cell set corresponding to downlink control information for scheduling multiple cells includes: receiving indication information sent by a network device in a first cell, wherein the indication information sent in multiple first cells is used to indicate multiple cell groups; determining a target cell group to which the first cell belongs in the multiple cell groups, and a set of cell groups to which the target cell group belongs; and determining a cell set corresponding to the set of cell groups.

[0267] In one embodiment, a network device can send indication information to a terminal from multiple first cells. The indication information can indicate the association between the value of the Carrier Indication Field (CIF) corresponding to the first cell from which the indication information is sent and the scheduling cell identifier. The network device can determine multiple cell groups based on the association corresponding to each first cell. Specifically, the association can be the association between the value of the Carrier Indication Field (CIF-InScheduingCell) within the scheduling cell and the scheduling cell identifier.

[0268] The role of the association relationship has been described in the previous terminal-side embodiments and will not be repeated here. The method by which the network device determines multiple cell groups is the opposite of the method by which the terminal determines multiple cells. The network device can determine multiple cell groups before sending the indication information and instructs the terminal through the indication information. The terminal can only determine multiple cells after receiving the indication information. Furthermore, the method by which the network device determines at least one cell set corresponding to the downlink control information used for scheduling multiple cells also corresponds to the terminal-side embodiments and will not be repeated here.

[0269] Corresponding to the aforementioned embodiments of the cell determination method, this disclosure also provides embodiments of the cell determination apparatus.
