[0034] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.
[0035] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present disclosure.

It should also be understood that the term "and / or" as used herein refers to and includes any or all possible combinations of one or more associated listed items.
[0036] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".
[0037] For the purpose of brevity and ease of understanding, the terms "greater than," "less than," "higher than," and "lower than" are used herein to describe size relationships. However, those skilled in the art will understand that the term "greater than" also encompasses the meaning of "greater than or equal to," and "less than" also encompasses the meaning of "less than or equal to," and the term "higher than" also encompasses the meaning of "higher than or equal to," and "lower than" also encompasses the meaning of "lower than or equal to."
[0038] Figure 1 This is a schematic flow chart illustrating a method for determining a set according to an embodiment of the present disclosure. The method for determining a set illustrated in this embodiment can be executed by a terminal, including but not limited to a mobile phone, tablet computer, wearable device, sensor, IoT device, or other communication device. The terminal can communicate with network devices, including but not limited to network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.
[0039] like Figure 1 As shown, the set determination method may include the following steps:
[0040] In step S101, a cell set to which a first cell belongs is determined, wherein downlink control information (DCI) used for scheduling multiple cells in the cell set (specifically, data of the scheduled cells, such as PUSCH and PDSCH) has the same size.
[0041] In one embodiment, the DCI used to schedule multiple cells may include DCI used to schedule uplink data of multiple cells, for example, it may be called DCI format 0_3, which can be used to schedule uplink data of multiple cells in the cell set; it may also include DCI used to schedule downlink data of multiple cells, for example, it may be called DCI format 1_3, which can be used to schedule downlink data of multiple cells in the cell set.
[0042] In one embodiment, downlink control information used to schedule multiple cells may be referred to as MC-DCI, where MC can represent either multi-carrier or multi-cell. Since MC-DCI is a newly introduced DCI compared to legacy DCI, its size (also translated as "size" refers to the number of occupied bits) may differ from that of legacy DCI. This leads to an increase in the number of sizes, and the excessive number of DCI sizes increases the complexity of terminal blind DCI detection.
[0043] According to an embodiment of the present disclosure, the terminal can determine the cell set to which the first cell (not a specific cell, but any service cell) belongs. For MC-DCI of the same format that schedules multiple cells in the same cell set, the terminal can determine that they have the same size, thereby performing blind detection according to the same size, thereby reducing the number of DCI sizes that need to be considered during the blind detection process, which is conducive to reducing the complexity of blind detection.
[0044] That is, for cells belonging to the same set, when the terminal receives MC-DCI for scheduling the cell, for MC-DCI corresponding to the same format, the terminal expects to perform blind detection according to the same size, or it can be described as for cells belonging to the same set, when the terminal receives MC-DCI for scheduling the cell, for MC-DCI corresponding to the same format, the terminal does not expect to perform blind detection according to different sizes.
[0045] In one embodiment, different cell sets include different cells, that is, the same cell does not belong to different cell sets, and different cell sets include different cells.
[0046] Taking two cell sets as an example, cell set #1 includes Cell#1, Cell#2, and Cell#3, and cell set #2 includes Cell#4, Cell#5, Cell#6, and Cell#7.
[0047] According to the embodiments of the present disclosure, for MC-DCI format 1_3 used for scheduling Cell#1 and Cell#2, and MC-DCI format 1_3 used for scheduling Cell#2 and Cell#3, since Cell#1, Cell#2, and Cell#3 all belong to cell set #1, blind detection can be performed according to the same size when receiving MC-DCI.
[0048] Similarly, for MC-DCI format 1_3 used to schedule Cell#4 and Cell#5, and MC-DCI format 1_3 used to schedule Cell#5 and Cell#6, since Cell#4, Cell#5, and Cell#6 all belong to cell set #2, when receiving MC-DCI, blind detection can be performed according to the same size.
[0049] For different cell sets, the MC-DCI sizes of the cells in the scheduled cell set may be the same or different, and this disclosure does not impose any restrictions on this. For example, the MC-DCI sizes of multiple cells in scheduled cell set #1 and multiple cells in scheduled cell set #2 may be the same or different, and the specific size can be determined based on actual conditions.
[0050] It can be seen that according to the embodiments of the present disclosure, for cells in the same cell set, no matter which cells are in the MC-DCI scheduling set, the terminal can blindly detect MC-DCI according to the same size, without having to blindly detect according to different sizes each time MC-DCI is received.
[0051] In one embodiment, the downlink control information of the same format used for scheduling multiple cells in the cell set has the same size.
[0052] Taking the above-mentioned cell set #1 as an example, for DCIs of the same format of multiple cells in the scheduling cell set #1, the terminal can perform blind detection according to the same size.
[0053] For example, a terminal receives DCI format 0_3 once for scheduling uplink data for Cell#1 and Cell#2 in cell set #1, and then receives DCI format 0_3 again for scheduling uplink data for Cell#2 and Cell#3 in cell set #1. Since Cell#1, Cell#2, and Cell#3 all belong to cell set #1, blind detection of DCI format 0_3 can be performed using the same size for the two DCI format 0_3 receptions.
[0054] Based on this, for MC-DCI of the same format that schedules multiple cells in the same cell set, the terminal can determine that they have the same size, and thus perform blind detection according to the same size, thereby reducing the number of DCI sizes that need to be considered for DCI of the same format during the blind detection process, which is conducive to reducing the complexity of blind detection.
[0055] Figure 2 FIG. 1 is a schematic flow chart of another set determination method according to an embodiment of the present disclosure. Figure 2 As shown, determining the cell set to which the first cell belongs includes:
[0056] In step S201, the correspondence between the cell and the cell set is determined according to the indication information sent by the network device;
[0057] In step S202, the cell set to which the first cell belongs is determined according to the corresponding relationship.
[0058] In one embodiment, the correspondence between cells and cell sets can be indicated by a network device. For example, the network device can indicate the correspondence between cells and cell sets to the terminal through indication information, and then the terminal can determine the cell set to which the first cell belongs based on the correspondence between the cells and cell sets.
[0059] It should be noted that the cell in the corresponding relationship indicated by the network device can be selected by the network device as needed, or determined by the network device according to predefined rules. For example, the cell specified by the predefined rule can be any cell, or a cell supported by the network device, or a cell supported by the terminal, or a cell currently providing services to the terminal (including a primary cell, a secondary cell, etc.), or a physical uplink control channel (PUCCH) group or a cell in a physical uplink control channel cell.
[0060] In one embodiment, the cells in the cell set belong to the same physical uplink control channel group or physical uplink control channel cell.
[0061] In one embodiment, the number of cells in the cell set is less than or equal to the maximum number of cells that can be scheduled by the downlink control information for scheduling multiple cells; or
[0062] The number of cells in the cell set is greater than the maximum number, or less than the maximum number, or equal to the maximum number; or,
[0063] The number of cells in the cell set is the same as the number of cells included in the physical uplink control channel group or physical uplink control channel cell corresponding to the downlink control information for scheduling multiple cells.
[0064] For example, the number of cells in the cell set is n c , the maximum number of cells that MC-DCI can schedule is n max , you can limit n c Less than n max ; or no limit on n c The size of n c Can be greater than n max , can also be less than n max , can also be equal to n max ; or you can limit n c The amount of data contained in the PUCCH group or PUCCH cell corresponding to the MC-DCI is the same as that of the cell.
[0065] In one embodiment, the maximum number is the maximum number of cells that can be scheduled by the downlink control information (e.g., DCI 0_X, where X can be 0, 1, 2, 3, etc.) used to schedule the physical uplink shared channels (Physical Uplink Shared Channel, PUSCH) of multiple cells; or, the maximum number is the maximum number of cells that can be scheduled by the downlink control information (e.g., DCI 1_X, where X can be 0, 1, 2, 3, etc.) used to schedule the physical downlink shared channels (Physical Downlink Shared Channel, PDSCH) of multiple cells.
[0066] In one embodiment, the method further includes: when the first cell receives the downlink control information, determining that the downlink control information is used to schedule one or more cells in the cell set to which the first cell belongs. That is, when the terminal receives MC-DCI in the first cell, if it is determined that the first cell belongs to the first cell set, then the MC-DCI can be determined to be used only for scheduling one or more cells in the first cell set. Accordingly, the range of cells considered when determining the cells scheduled by the MC-DCI can be reduced, which helps simplify the process of determining the cells scheduled by the MC-DCI.
[0067] In one embodiment, the indication information includes but is not limited to a Radio Resource Control (RRC) message, a Media Access Control Control Element (MAC CE), a DCI, etc. The following mainly illustrates the technical solution of the present disclosure in the case where the indication information is an RRC message.
[0068] Figure 3 FIG. 1 is a schematic flow chart of another set determination method according to an embodiment of the present disclosure. Figure 3 As shown, determining the correspondence between the cell and the cell set according to the indication information sent by the network device includes:
[0069] In step S301, indication information sent by a network device is received in the first cell;
[0070] In step S302, the identifier of the cell set to which the first cell belongs is determined according to the indication information.
[0071] In one embodiment, the terminal may determine the identifier of the set to which the first cell belongs based on the indication information received in the first cell, that is, the indication information sent by the network device to the terminal in the first cell may indicate the identifier of the cell set to which the first cell belongs.
[0072] For example, the network device includes the cell set identifier 1 in the indication information sent to the terminal in the first cell, and includes the cell set identifier 2 in the indication information sent to the terminal in the second cell. Then the terminal can determine that the first cell belongs to the cell set identified as 1, and determine that the second cell belongs to the cell set identified as 2.
[0073] Figure 4 It is a schematic diagram of an application scenario according to an embodiment of the present disclosure.
[0074] like Figure 4 As shown, taking 8 cells as an example, they are Cell#1, Cell#2, Cell#3, Cell#4, Cell#5, Cell#6, Cell#7, and Cell#8.
[0075] The indication information received by the terminal in Cell#1, Cell#2, Cell#3, and Cell#4 includes the cell set identifier of 1, and the indication information received in Cell#5, Cell#6, Cell#7, and Cell#8 includes the cell set identifier of 2. Then the terminal can determine that Cell#1, Cell#2, Cell#3, and Cell#4 belong to the cell set identified as 1 (cell set id=1), and determine that Cell#5, Cell#6, Cell#7, and Cell#8 belong to the cell set identified as 2 (cell set id=2).
[0076] Figure 5 FIG. 1 is a schematic flow chart of another set determination method according to an embodiment of the present disclosure. Figure 5 As shown, determining the correspondence between the cell and the cell set according to the indication information sent by the network device includes:
[0077] In step S501, indication information sent by a network device is received in the first cell;
[0078] In step S502, multiple cell groups are determined according to the indication information received from multiple first cells;
[0079] In step S503, determining a target cell group to which the first cell belongs among the multiple cell groups, and a cell group set to which the target cell group belongs;
[0080] In step S504, a cell set corresponding to the cell group set is determined as the cell set to which the first cell belongs.
[0081] In one embodiment, a terminal may receive indication information sent by a network device in multiple first cells, wherein the indication information may indicate an association relationship between a value of a carrier indicator field (CIF) corresponding to the first cell in which the indication information is received and a scheduling cell identifier, and the terminal may determine multiple cell groups based on the association relationship corresponding to each first cell. The association relationship may specifically be an association relationship between a value of a carrier indicator field (cif-InScheduingCell) in a scheduling cell and a scheduling cell identifier.
[0082] The terminal may determine whether the first cell is the cell scheduled by the MC-DCI received in the second cell based on the following manner:
[0083] Determine the serving cell configuration (ServingCellConfig) of the information element (IE) in the RRC message, then determine the cross-carrier scheduling configuration (CrossCarrierSchedulingConfig) in the serving cell configuration, and then determine the scheduling cell information (schedulingCellInfo) in the cross-carrier scheduling configuration. When the schedulingCellInfo indication value is other (other), further determine the scheduling cell identifier (schedulingCellId) and cif-InScheduingCell in schedulingCellInfo.
[0084] When 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 MC-DCI received in the second cell, it can be determined that the MC-DCI received in the second cell is used to schedule the first cell.
[0085] The association relationship can define a correspondence between the values of multiple carrier indicator fields and multiple scheduling cell identifiers, and is not limited to the association of one carrier indicator field value with one scheduling cell identifier. Therefore, when the network device sends MC-DCI to the terminal based on the association relationship, it is beneficial to improve the scheduling flexibility of MC-DCI for the first cell. For example, the network device can set the CIF value in the sent MC-DCI based on the association relationship corresponding to the first cell to be scheduled, thereby dynamically adjusting the multiple cells (cell groups) to be scheduled.
[0086] Figure 6 It is a schematic diagram of another application scenario according to an embodiment of the present disclosure.
[0087] like Figure 6 As shown, taking three cells, Cell#0 (cell ID is 0), Cell#1 (cell ID is 1) and Cell#2 (cell ID is 2), as an example, the network device carries indication information through an RRC message.
[0088] The association relationship carried in the RRC message sent by the network device in Cell#0 to the terminal is table1-0, the association relationship carried in the RRC message sent by Cell#1 to the terminal is table1-1, and the association relationship carried in the RRC message sent by Cell#2 to the terminal is table1-2.
[0089] The association relationship contained in table 1-0 is: the value of the carrier indicator field is 0 and the corresponding scheduling cell identifier is 2;
[0090] Table 1-1 contains the following association: a carrier indicator field value of 1 corresponds to a scheduling cell ID of 0, and a carrier indicator field value of 2 corresponds to a scheduling cell ID of 0. Therefore, when the CIF value in the MC-DCI sent by the network device to the terminal in the second cell with cell ID 0 is 1, scheduling can be performed on the first cell (e.g., Cell#1). When the CIF value in the MC-DCI sent to the terminal in the second cell with cell ID 0 is 2, scheduling can also be performed on the first cell (e.g., Cell#1). The CIF value can range from 0 to 7 and can, of course, be adjusted as needed.
[0091] The association relationship contained in table 1-2 is: the value of the carrier indication field is 1 corresponding to the scheduling cell identifier 0, and the value of the carrier indication field is 3 corresponding to the scheduling cell identifier 0. Therefore, when the CIF value in the MC-DCI sent by the network device to the terminal in the second cell with the cell identifier 0 is 1, the first cell (for example, Cell#2) can be scheduled. When the CIF value in the MC-DCI sent to the terminal in the second cell with the cell identifier 2 is 3, the first cell (for example, Cell#2) can also be scheduled.
[0092] Among them, since table1-0 is the association relationship received in the scheduling cell Cell#0, and the MC-DCI received in the scheduling cell can be used for self-scheduling, that is, the MC-DCI received in Cell#0 can be used to schedule Cell#0 itself, the association relationship corresponding to Cell#0, in addition to the correspondence contained in table1-0, can also additionally include: the value of the carrier indication field is 0 corresponding to the scheduling cell identifier of 0, the value of the carrier indication field is 1 corresponding to the scheduling cell identifier of 0, the value of the carrier indication field is 2 corresponding to the scheduling cell identifier of 0, and the value of the carrier indication field is 3 corresponding to the scheduling cell identifier of 0.
[0093] It should be noted that Figure 6 The blank portion of the table shown can also be used to set the value of the carrier indicator field and the scheduling cell identifier, but this is not used in the example process of this embodiment and is therefore not shown. In addition, the number of rows in the table is not limited to the four rows shown in the figure, and the number of rows can be reduced or increased as needed.
[0094] Based on the above association relationship, it can be determined that when the value of the carrier indication field is 0 (00), MC-DCI can schedule Cell#0; when the value of the carrier indication field is 1 (01), MC-DCI can schedule Cell#0, Cell#1, and Cell#2; when the value of the carrier indication field is 2 (10), MC-DCI can schedule Cell#0 and Cell#1; when the value of the carrier indication field is 3 (11), MC-DCI can schedule Cell#0 and Cell#2. Based on this, the relationship between the value of the carrier indication field and the scheduled cell that can be determined by the terminal is shown in Table 1 below:
[0095] CIF Cell Group 00 {0} 01 {0,1,2} 10 {0,1} 11 {0,2}
[0096] Table 1
[0097] Among them, the cell group can be a cell group composed of cells corresponding to the value of each carrier indication field in the association relationship indicated by the indication information received by each first cell. As shown in representation 1, the multiple cell groups are {0}, {0,1,2}, {0,1}, {0,2}.
[0098] It is understood that each element in the tables shown in all embodiments of the present disclosure exists independently. These elements are illustratively listed in the same table, 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 value of any other element in the table. Therefore, those skilled in the art will understand that the value of each element in the table represents an independent embodiment.
[0099] Since the cell group also has a cell group set to which it belongs, and the cell group set can correspond to the cell set, 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. Then, it can be determined that the first cell belongs to the determined cell set.
[0100] Among them, the cells included in the cell groups in different cell group sets are different. For example, cell group set #1 includes cell group #1 and cell group #2, and cell group set #2 includes cell group #3 and cell group #4. Then the cells included in cell group #1 and cell group #2 are different from the cells included in cell group #3 and cell group #4.
[0101] Figure 7 FIG. 1 is a schematic flow chart of another set determination method according to an embodiment of the present disclosure. Figure 7 As shown, the method further includes:
[0102] In step S701, at least one cell group set is determined based on the multiple cell groups, wherein a first cell group in a first cell group set includes at least the same cells as a second cell group in the first cell group set.
[0103] In one embodiment, after determining multiple cell groups, the terminal can determine a cell group set based on the multiple cell groups, wherein the cell groups containing the same cells can be divided into the same cell group set. 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 divided into the same cell group set, for example, in the first cell group set.
[0104] Then, a cell group containing the same cell as any cell group in the first cell group set can be determined from the other cell groups, and the determined cell group can also be included in the first cell group set. Similarly, the determination of the first cell group set can be completed. Further cell group sets can then be determined based on the method used to determine the first cell group set.
[0105] It should be noted that the first cell group and the second cell group in the same cell group set are different. The first cell group and the second cell group do not specifically refer to a certain cell, but are any cell group in a cell group set.
[0106] For example, take the following cell groups as examples to determine the cell group set:
[0107] {0,1,2,3},{3},{5,6,7},{3,4,5,6},{8,9},{8};
[0108] First, we can consider any one of the cell groups. For example, we can first consider the cell group {0,1,2,3}. We can determine that the cell group {3} and the cell group {3,4,5,6} contain the same cell Cell#3 as the cell group {0,1,2,3}. Then, the three cell groups {3}, {3,4,5,6}, and {0,1,2,3} can be divided into the same cell group set, for example, called the first cell group set.
[0109] Then, we can determine the cell groups in other cell groups that contain the same cells as any cell group in the first cell group set. It can be determined that the cell group {5, 6, 7} and the cell group {3, 4, 5, 6} in the first cell group contain the same cells Cell#5 and Cell#6, so the cell group {5, 6, 7} can also be divided into the first cell group set.
[0110] Since the cell groups {8, 9} and {8} do not contain the same cells as any of the cell groups in the first cell group set, the first cell group set is determined, and the second cell group set can be determined. For example, according to the above method, the second cell group set can be determined to include the cell groups {8, 9} and {8}.
[0111] For cell groups, Figure 4 In the case of the illustrated embodiment, for example, the indication information received in Cell#1, Cell#2, Cell#3, and Cell#4 includes a cell set identifier of 1, and the indication information received in Cell#5, Cell#6, Cell#7, and Cell#8 includes a cell set identifier of 2. The terminal determines that Cell#1, Cell#2, Cell#3, and Cell#4 belong to the cell set identified as 1 (cell set id=1), and determines that Cell#5, Cell#6, Cell#7, and Cell#8 belong to the cell set identified as 2 (cell set id=2).
[0112] Subsequently, the MC-DCI received by the terminal in the scheduling cell is used to schedule multiple cells (Cell#1, Cell#2, Cell#3, and Cell#4), and can also be used to schedule multiple cells (Cell#2 and Cell#3). Another MC-DCI received in the scheduling cell can be used to schedule multiple cells (Cell#5, Cell#6, Cell#7, and Cell#8), and can also be used to schedule multiple cells (Cell#6 and Cell#7). Thus, four cell groups {1,2,3,4}, {2,3}, {5,6,7,8}, and {6,7}} can be determined, as well as two cell group sets {{1,2,3,4}, {2,3}}, {{5,6,7,8}, and {6,7}}. Different cell group sets can be determined by the cells scheduled by MC-DCI sent by different cells.
[0113] Figure 8 FIG. 1 is a schematic flow chart of another set determination method according to an embodiment of the present disclosure. Figure 8 As shown, determining the cell set corresponding to the cell group set includes:
[0114] In step S801, a cell set consisting of cells included in the cell group in the cell group set is determined.
[0115] In one embodiment, the method of determining the cell set corresponding to the cell group set may be to determine the cells included in the cell groups in the cell group set, and then use the set composed of the determined cells as the cell set corresponding to the cell group set.
[0116] Figure 9This is another schematic diagram of an application scenario according to an embodiment of the present disclosure.
[0117] Taking the first cell group set and the second cell group set determined in the above 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}}.
[0118] Then according to this embodiment, it can be determined that the cells included in the cell group in the first cell group set are Cell#0, Cell#1, Cell#2, Cell#3, Cell#4, Cell#5, Cell#6, and Cell#7, then it can be determined that the cell set constituted by these cells is {0,1,2,3,4,5,6,7}, that is, the cell set corresponding to the first cell group set is {0,1,2,3,4,5,6,7}. Similarly, it can be determined that the cell set corresponding to the second cell group set is {8,9}.
[0119] The above embodiments mainly consider that the sizes of DCIs used for scheduling multiple cells in a cell set are the same. In fact, the embodiments of the present disclosure can also be applied to scheduling cell groups, that is, the sizes of DCIs used for scheduling multiple cell groups in a cell group set are the same.
[0120] The present disclosure also proposes a set determination method, which is executed by a terminal, and the method includes: determining a first cell group to which a first cell belongs; determining a first cell group set to which the first cell group belongs, wherein the size of the downlink control information used to schedule multiple cell groups in the first cell group set is the same.
[0121] According to an embodiment of the present disclosure, the terminal can determine the first cell group set to which the first cell group (not specifically referring to a certain cell group, but can be a cell group composed of any service cells) belongs. For the MC-DCI for scheduling multiple cell groups in the same cell group set, the terminal can determine that they have the same size, thereby performing blind detection according to the same size, thereby reducing the number of DCI sizes that need to be considered during the blind detection process, which is conducive to reducing the complexity of blind detection.
[0122] In one embodiment, different cell group sets include different cell groups, that is, the same cell group does not belong to different cell group sets, and different cell group sets include different cell groups.
[0123] In one embodiment, downlink control information of the same format used to schedule multiple cell groups in the first cell group set has the same size. That is, for MC-DCI of the same format used to schedule multiple cell groups in the same cell group set, the terminal can determine that they have the same size, and thus perform blind detection based on the same size, thereby reducing the number of DCI sizes that need to be considered for DCI of the same format during the blind detection process, which is conducive to reducing the complexity of blind detection.
[0124] In one embodiment, the method further comprises:
[0125] receiving, in the first cell, indication information sent by the network device;
[0126] determining, according to the indication information, a plurality of cell groups and a first cell set to which the first cell belongs;
[0127] The first cell group set is determined based on the cell groups in the multiple cell groups that include the cells in the first cell set.
[0128] In one embodiment, a terminal may receive indication information sent by a network device in multiple first cells, wherein the indication information may indicate an association relationship between a value of a carrier indication field corresponding to the first cell in which the indication information is received and a scheduling cell identifier. The terminal may determine multiple cell groups based on the association relationship corresponding to each first cell. The association relationship may specifically be an association relationship between a value of cif-InScheduingCell and a scheduling cell identifier.
[0129] The method for determining multiple cell groups based on the indication information is similar to the embodiment described above and will not be repeated here. Regarding determining the first cell set to which the first cell belongs based on the indication information, the identifier of the cell set to which the first cell belongs can be determined based on the indication information, thereby determining that the first cell belongs to the cell set corresponding to the identifier. The specific example method is also described in the embodiment described above and will not be repeated here. This section mainly describes how to determine the first cell group set.
[0130] For example, based on the embodiment shown above, the cell group includes:
[0131] {0,1,2,3},{3},{5,6,7},{3,4,5,6},{8,9},{8};
[0132] For example, if the indication information includes a cell set identifier of 1, it can be determined that the first cell belongs to the cell set identified as 1. For example, the first cell set identified as 1 is {0, 1, 2, 3, 4, 5, 6, 7}.
[0133] It can be further determined that the multiple cell groups include the cell groups in the first cell set {0,1,2,3,4,5,6,7}, and 4 cell groups {0,1,2,3}, {3}, {5,6,7}, and {3,4,5,6} in the multiple cell groups include cells in the first cell set, and then these cell groups including the cells in the first cell set {0,1,2,3,4,5,6,7} can be divided into a cell group set, that is, {{0,1,2,3},{3},{3,4,5,6},{5,6,7}}.
[0134] For example, if the indication information includes a cell set identifier of 2, it can be determined that the first cell belongs to the cell set identified as 2, for example, the first cell set identified as 2 is {8, 9}.
[0135] It can be further determined that the cell groups in the multiple cell groups include the cells in the first cell set {8,9}, and two cell groups {8,9} and {8} in the multiple cell groups include the cells in the first cell set {8,9}. These cell groups including the cells in the first cell set {8,9} can then be divided into a cell group set, namely {{8,9}, {8}}.
[0136] Figure 10 This is a schematic flow chart illustrating a method for determining a set according to an embodiment of the present disclosure. The method for determining a set illustrated 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, a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station. The terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, an IoT device, and other communication devices.
[0137] like Figure 10 As shown, the set determination method may include the following steps:
[0138] In step S1001, a cell set to which a first cell belongs is determined, wherein downlink control information used for scheduling multiple cells in the cell set has the same size.
[0139] In one embodiment, the DCI used to schedule multiple cells may include DCI used to schedule uplink data of multiple cells, for example, it may be called DCI format 0_3, which can be used to schedule uplink data of multiple cells in the cell set; it may also include DCI used to schedule downlink data of multiple cells, for example, it may be called DCI format 1_3, which can be used to schedule downlink data of multiple cells in the cell set.
[0140] In one embodiment, downlink control information used to schedule multiple cells may be referred to as MC-DCI, where MC can represent either multi-carrier or multi-cell. Since MC-DCI is a newly introduced DCI compared to legacy DCI, its size (also translated as "size" refers to the number of occupied bits) may differ from that of legacy DCI. This leads to an increase in the number of sizes, and the excessive number of DCI sizes increases the complexity of terminal blind DCI detection.
[0141] According to an embodiment of the present disclosure, the network device can determine the cell set to which the first cell (not a specific cell, but any service cell) belongs. For the MC-DCI format for scheduling multiple cells in the same cell set, the network device can set the same size, so that the terminal performs blind detection on the MC-DCI for scheduling multiple cells in the same cell set according to the same size, so as to reduce the number of DCI sizes that need to be considered during the blind detection process, which is conducive to reducing the complexity of blind detection.
[0142] That is, for cells belonging to the same set, when the network device sends MC-DCI to schedule multiple cells in the set, the same size can be set for each MC-DCI sent that corresponds to the same format. Therefore, for cells belonging to the same set, when the terminal receives MC-DCI for scheduling cells, for MC-DCI corresponding to the same format, the terminal expects to perform blind detection based on the same size. Alternatively, it can be described as follows: for cells belonging to the same set, when the terminal receives MC-DCI for scheduling cells, for MC-DCI corresponding to the same format, the terminal does not expect to perform blind detection based on different sizes.
[0143] In one embodiment, different cell sets include different cells, that is, the same cell does not belong to different cell sets, and different cell sets include different cells.
[0144] Taking two cell sets as an example, cell set #1 includes Cell#1, Cell#2, and Cell#3, and cell set #2 includes Cell#4, Cell#5, Cell#6, and Cell#7.
[0145] According to the embodiments of the present disclosure, for MC-DCI format 1_3 used for scheduling Cell#1 and Cell#2, and MC-DCI format 1_3 used for scheduling Cell#2 and Cell#3, since Cell#1, Cell#2, and Cell#3 all belong to cell set #1, the same size can be set when sending MC-DCI;
[0146] Similarly, for MC-DCI format 1_3 used to schedule Cell#4 and Cell#5, and MC-DCI format 1_3 used to schedule Cell#5 and Cell#6, since Cell#4, Cell#5, and Cell#6 all belong to cell set #2, the same size can be set when sending MC-DCI.
[0147] For different cell sets, the MC-DCI sizes of the cells in the scheduled cell set may be the same or different, and this disclosure does not impose any restrictions on this. For example, the MC-DCI sizes of multiple cells in scheduled cell set #1 and multiple cells in scheduled cell set #2 may be the same or different, and the specific size can be determined based on actual conditions.
[0148] It can be seen that according to the embodiments of the present disclosure, for cells in the same cell set, no matter which cells are in the MC-DCI scheduling set, the network device can set the size of the MC-DCI to be the same, so that the terminal can blindly detect the MC-DCI according to the same size without having to blindly detect according to different sizes each time the MC-DCI is received.
[0149] In one embodiment, the downlink control information of the same format used for scheduling multiple cells in the cell set has the same size.
[0150] Taking the above-mentioned cell set #1 as an example, for DCIs of the same format of multiple cells in the scheduling cell set #1, the terminal can perform blind detection according to the same size.
[0151] For example, the network sends DCI format 0_3 once to schedule uplink data for Cell#1 and Cell#2 in cell set #1, and then sends DCI format 0_3 again to schedule uplink data for Cell#2 and Cell#3 in cell set #1. Since Cell#1, Cell#2, and Cell#3 all belong to cell set #1, the same size can be set for the two DCI format 0_3 transmissions, allowing the terminal to blindly detect DCI format 0_3 based on the same size.
[0152] Based on this, for MC-DCI of the same format scheduling multiple cells in the same cell set, the network equipment can set the same size, so that the terminal can perform blind detection according to the same size, thereby reducing the number of DCI sizes that need to be considered for DCI of the same format during the blind detection process, which is conducive to reducing the complexity of blind detection.
[0153] Figure 11FIG. 1 is a schematic flow chart of another set determination method according to an embodiment of the present disclosure. Figure 11 As shown, the method further includes:
[0154] In step S1101, indication information is sent to a terminal, where the indication information is used to indicate a correspondence between a cell and a cell set.
[0155] In one embodiment, the correspondence between cells and cell sets can be indicated by a network device. For example, the network device can indicate the correspondence between cells and cell sets to the terminal through indication information, and then the terminal can determine the cell set to which the first cell belongs based on the correspondence between the cells and cell sets.
[0156] It should be noted that the cell in the corresponding relationship indicated by the network device can be selected by the network device as needed, or determined by the network device according to predefined rules. For example, the cell specified by the predefined rule can be any cell, or a cell supported by the network device, or a cell supported by the terminal, or a cell currently providing services to the terminal (including a primary cell, a secondary cell, etc.), or a cell in a physical uplink control channel group (PUCCH group) or a physical uplink control channel cell (PUCCH Cell).
[0157] In one embodiment, the cells in the cell set belong to the same physical uplink control channel group or physical uplink control channel cell.
[0158] In one embodiment, the number of cells in the cell set is less than or equal to the maximum number of cells that can be scheduled by the downlink control information for scheduling multiple cells; or
[0159] The number of cells in the cell set is greater than the maximum number, or less than the maximum number, or equal to the maximum number; or,
[0160] The number of cells in the cell set is the same as the number of cells included in the physical uplink control channel group or physical uplink control channel cell corresponding to the downlink control information for scheduling multiple cells.
[0161] For example, the number of cells in the cell set is n c , the maximum number of cells that MC-DCI can schedule is n max , you can limit n c Less than n max ; or no limit on n c The size of n c Can be greater than n max , can also be less than n max , can also be equal to n max; or you can limit n c The amount of data contained in the PUCCH group or PUCCH cell corresponding to the MC-DCI is the same as that of the cell.
[0162] In one embodiment, the maximum number is the maximum number of cells that can be scheduled by the downlink control information (e.g., DCI 0_X, where X can be 0, 1, 2, 3, etc.) used to schedule the physical uplink shared channel PUSCH of multiple cells; or, the maximum number is the maximum number of cells that can be scheduled by the downlink control information (e.g., DCI 1_X, where X can be 0, 1, 2, 3, etc.) used to schedule the physical downlink shared channel PDSCH of multiple cells.
[0163] In one embodiment, the method further includes: sending downlink control information to the terminal in the first cell, wherein the downlink control information is used to schedule one or more cells in a cell set to which the first cell belongs.
[0164] That is, when the network device sends MC-DCI to the terminal in the first cell, if it is determined that the first cell belongs to the first cell set, then the MC-DCI sent is only used to schedule one or more cells in the first cell set. Accordingly, the range of cells considered when determining the cells scheduled by the MC-DCI can be reduced, which is conducive to simplifying the process of determining the cells scheduled by the MC-DCI.
[0165] In one embodiment, the indication information includes but is not limited to a radio resource control (RRC) message, a media access control layer control element (MAC CE), a DCI, etc. The following mainly describes the technical solution of the present disclosure in the case where the indication information is an RRC message.
[0166] Figure 12 FIG. 1 is a schematic flow chart of another set determination method according to an embodiment of the present disclosure. Figure 12 As shown, the sending of instruction information to the terminal includes:
[0167] In step S1201, indication information is sent to the terminal in the first cell, where the indication information is used to indicate an identifier of a cell set to which the first cell belongs.
[0168] In one embodiment, the network device may send indication information to the terminal in the first cell to indicate the identifier of the cell set to which the first cell belongs.
[0169] For example, the network device includes the cell set identifier 1 in the indication information sent to the terminal in the first cell, and includes the cell set identifier 2 in the indication information sent to the terminal in the second cell. This can indicate that the first cell belongs to the cell set identified as 1, and that the second cell belongs to the cell set identified as 2.
[0170] Figure 13 FIG. 1 is a schematic flow chart of another set determination method according to an embodiment of the present disclosure. Figure 13 As shown, the sending of instruction information to the terminal includes:
[0171] In step S1301, indication information is sent to the terminal in multiple first cells, where the indication information sent in the multiple first cells is used to indicate multiple cell groups;
[0172] Determining the cell set to which the first cell belongs includes:
[0173] In step S1302, determining a target cell group to which the first cell belongs among the multiple cell groups, and a cell group set to which the target cell group belongs;
[0174] In step S1303, a cell set corresponding to the cell group set is determined as the cell set to which the first cell belongs.
[0175] In one embodiment, the network device may send indication information to the terminal in multiple first cells, wherein the indication information may indicate an association relationship between a value of a carrier indication field CIF corresponding to the first cell where the indication information is sent and a scheduling cell identifier, and the network device may determine multiple cell groups based on the association relationship corresponding to each first cell. The association relationship may specifically be an association relationship between a value of a carrier indication field (cif-InScheduingCell) in a scheduling cell and a scheduling cell identifier.
[0176] The role of the association relationship has been described in the previous embodiment corresponding to the terminal side and will not be repeated here. The way in which the network device determines multiple cell groups is opposite to the way in which the terminal determines multiple cells. The network device can determine multiple cell groups before sending the indication information and indicate it to the terminal through the indication information, while the terminal can only determine multiple cells after receiving the indication information. This will not be repeated here.
[0177] Figure 14 FIG. 1 is a schematic flow chart of another set determination method according to an embodiment of the present disclosure. Figure 14 As shown, the method further includes:
[0178] In step S1401, at least one cell group set is determined based on the multiple cell groups, wherein a first cell group in a first cell group set includes at least the same cells as a second cell group in the first cell group set.
[0179] In one embodiment, when the network device indicates multiple cell groups through indication information, a cell group set can be determined based on the multiple cell groups, wherein the cell groups containing the same cells can be divided into the same cell group set. 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 divided into the same cell group set, for example, in the first cell group set.
[0180] Then, a cell group containing the same cell as any cell group in the first cell group set can be determined from the other cell groups, and the determined cell group can also be included in the first cell group set. Similarly, the determination of the first cell group set can be completed. Further cell group sets can then be determined based on the method used to determine the first cell group set.
[0181] It should be noted that the first cell group and the second cell group in the same cell group set are different. The first cell group and the second cell group do not specifically refer to a certain cell, but are any cell group in a cell group set.
[0182] For example, take the following cell groups as examples to determine the cell group set:
[0183] {0,1,2,3},{3},{5,6,7},{3,4,5,6},{8,9},{8};
[0184] First, we can consider any one of the cell groups. For example, we can first consider the cell group {0,1,2,3}. We can determine that the cell group {3} and the cell group {3,4,5,6} contain the same cell Cell#3 as the cell group {0,1,2,3}. Then, the three cell groups {3}, {3,4,5,6}, and {0,1,2,3} can be divided into the same cell group set, for example, called the first cell group set.
[0185] Then, we can determine the cell groups in other cell groups that contain the same cells as any cell group in the first cell group set. It can be determined that the cell group {5, 6, 7} and the cell group {3, 4, 5, 6} in the first cell group contain the same cells Cell#5 and Cell#6, so the cell group {5, 6, 7} can also be divided into the first cell group set.
[0186] Since the cell groups {8, 9} and {8} do not contain the same cells as any of the cell groups in the first cell group set, the first cell group set is determined, and the second cell group set can be determined. For example, according to the above method, the second cell group set can be determined to include the cell groups {8, 9} and {8}.
[0187] For cell groups, Figure 4In the case of the illustrated embodiment, for example, the network device determines that Cell#1, Cell#2, Cell#3, and Cell#4 belong to a cell set identified as 1 (cell set id=1), and determines that Cell#5, Cell#6, Cell#7, and Cell#8 belong to a cell set identified as 2 (cell set id=2). Then, the indication information sent by Cell#1, Cell#2, Cell#3, and Cell#4 includes the identification of the cell set as 1, and the indication information sent by Cell#5, Cell#6, Cell#7, and Cell#8 includes the identification of the cell set as 2.
[0188] Subsequently, the network device can send MC-DCI to the terminal in the scheduling cell for scheduling multiple cells (Cell#1, Cell#2, Cell#3, and Cell#4), or for scheduling multiple cells (Cell#2 and Cell#3). Another MC-DCI sent in the scheduling cell can be used to schedule multiple cells (Cell#5, Cell#6, Cell#7, and Cell#8), or for scheduling multiple cells (Cell#6 and Cell#7). Thus, four cell groups ({1,2,3,4}, {2,3}, {5,6,7,8}, and {6,7}) can be determined, as well as two cell group sets ({1,2,3,4}, {2,3}}, {{5,6,7,8}, and {6,7}}). Different cell group sets can be determined by the cells scheduled by MC-DCI sent by different cells.
[0189] Figure 15 FIG. 1 is a schematic flow chart of another set determination method according to an embodiment of the present disclosure. Figure 15 As shown, determining the cell set corresponding to the cell group set includes:
[0190] In step S1501, a cell set consisting of cells included in the cell group in the cell group set is determined.
[0191] In one embodiment, the method of determining the cell set corresponding to the cell group set may be to determine the cells included in the cell groups in the cell group set, and then use the set composed of the determined cells as the cell set corresponding to the cell group set.
[0192] Taking the first cell group set and the second cell group set determined in the above 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}}.
[0193] Then according to this embodiment, it can be determined that the cells included in the cell group in the first cell group set are Cell#0, Cell#1, Cell#2, Cell#3, Cell#4, Cell#5, Cell#6, and Cell#7, then it can be determined that the cell set constituted by these cells is {0,1,2,3,4,5,6,7}, that is, the cell set corresponding to the first cell group set is {0,1,2,3,4,5,6,7}. Similarly, it can be determined that the cell set corresponding to the second cell group set is {8,9}.
[0194] The present disclosure also proposes a set determination method, which is executed by a network device, and the method includes: determining a first cell group to which a first cell belongs; determining a first cell group set to which the first cell group belongs, wherein the size of the downlink control information used to schedule multiple cell groups in the first cell group set is the same.
[0195] According to an embodiment of the present disclosure, the network device can determine the first cell group set to which the first cell group (not specifically referring to a certain cell group, but can be a cell group composed of any service cells) belongs. For the MC-DCI for scheduling multiple cell groups in the same cell group set, the network can set the same size, and the terminal can perform blind detection according to the same size, thereby reducing the number of DCI sizes that need to be considered during the blind detection process, which is conducive to reducing the complexity of blind detection.
[0196] In one embodiment, different cell group sets include different cell groups, that is, the same cell group does not belong to different cell group sets, and different cell group sets include different cell groups.
[0197] In one embodiment, downlink control information of the same format used to schedule multiple cell groups in the first cell group set has the same size. That is, for MC-DCI of the same format used to schedule multiple cell groups in the same cell group set, the terminal can determine that they have the same size, and thus perform blind detection based on the same size, thereby reducing the number of DCI sizes that need to be considered for DCI of the same format during the blind detection process, which is conducive to reducing the complexity of the blind detection.
[0198] In one embodiment, the method further comprises:
[0199] receiving, in a first cell, indication information sent to a terminal, where the indication information is used to indicate a plurality of cell groups and a first cell set to which the first cell belongs;
[0200] The first cell group set is determined based on the cell groups in the multiple cell groups that include the cells in the first cell set.
[0201] In one embodiment, a network device may send indication information to a terminal in multiple first cells, wherein the indication information may indicate that the received indication information is an association relationship between a value of a carrier indication field corresponding to the first cell and a scheduling cell identifier, and the terminal may determine multiple cell groups based on the association relationship corresponding to each first cell. The association relationship may specifically be an association relationship between a value of cif-InScheduingCell and a scheduling cell identifier.
[0202] The method for determining multiple cell groups based on the indication information is similar to the embodiment described above and will not be repeated here. Regarding determining the first cell set to which the first cell belongs based on the indication information, the identifier of the cell set to which the first cell belongs can be determined based on the indication information, thereby determining that the first cell belongs to the cell set corresponding to the identifier. The specific example method is also described in the embodiment described above and will not be repeated here. This section mainly describes how to determine the first cell group set.
[0203] For example, based on the embodiment shown above, the cell group includes:
[0204] {0,1,2,3},{3},{5,6,7},{3,4,5,6},{8,9},{8};
[0205] For example, if the indication information includes a cell set identifier of 1, it can be determined that the first cell belongs to the cell set identified as 1. For example, the first cell set identified as 1 is {0, 1, 2, 3, 4, 5, 6, 7}.
[0206] It can be further determined that the multiple cell groups include the cell groups in the first cell set {0,1,2,3,4,5,6,7}, and 4 cell groups {0,1,2,3}, {3}, {5,6,7}, and {3,4,5,6} in the multiple cell groups include cells in the first cell set, and then these cell groups including the cells in the first cell set {0,1,2,3,4,5,6,7} can be divided into a cell group set, that is, {{0,1,2,3},{3},{3,4,5,6},{5,6,7}}.
[0207] For example, if the indication information includes a cell set identifier of 2, it can be determined that the first cell belongs to the cell set identified as 2, for example, the first cell set identified as 2 is {8, 9}.
[0208] It can be further determined that the cell groups in the multiple cell groups include the cells in the first cell set {8,9}, and two cell groups {8,9} and {8} in the multiple cell groups include the cells in the first cell set {8,9}. These cell groups including the cells in the first cell set {8,9} can then be divided into a cell group set, namely {{8,9}, {8}}.
[0209] Corresponding to the aforementioned embodiments of the set determination method, the present disclosure also provides embodiments of a set determination device.
[0210] Figure 16 This is a schematic block diagram of a set determination apparatus according to an embodiment of the present disclosure. The set determination apparatus shown in this embodiment can be a terminal, or a device composed of modules within a terminal. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.
