Abstract

The present disclosure relates to a method and apparatus for scheduling determination, indication determination, and association relationship indication, wherein the scheduling determination method includes: determining the association relationship corresponding to a first cell; receiving downlink control information DCI for scheduling multiple cells in a second cell, and determining a first value of a carrier indicator field in the DCI; determining a scheduling cell identifier corresponding to the first value in the association relationship; and determining whether the first cell is a DCI-scheduled cell based on the relationship between the scheduling cell identifier corresponding to the first value and the identifier of the second cell. According to the present disclosure, the association relationship between the value of the carrier indicator field corresponding to each first cell and the scheduling cell identifier can be determined. Since the association relationship is not limited to one carrier indicator field value being associated with one scheduling cell identifier, the network device sends MC‑DCI to the terminal based on the association relationship, which is beneficial to improving the scheduling flexibility of MC‑DCI for the first cell.

[0010] According to a sixth aspect of an embodiment of the present disclosure, an indication determination device is proposed, which is executed by a terminal, and the device includes: a processing module, configured to determine an association relationship corresponding to a first cell, wherein the association relationship includes an association relationship between a value of a first information field and information indicated by the first information field for the first cell; receiving downlink control information DCI for scheduling multiple cells in a second cell, and determining the value of the first information field in the DCI; and in a case where the DCI schedules the first cell, determining the information indicated by the first information field in the DCI for the first cell based on the association relationship.

[0011] According to the seventh aspect of an embodiment of the present disclosure, an association relationship indication device is proposed, which is executed by a network device, and the device includes: a sending module, configured to indicate the association relationship corresponding to the first cell to the terminal, wherein the association relationship includes the association relationship between the value of the carrier indication domain and the scheduling cell identifier.

Furthermore, after receiving MC-DCI in the second cell, the terminal can determine the information indicated by the information field in the MC-DCI for each first cell based on the association relationship. Because the association relationship is configured separately for each first cell, the association relationship corresponding to each first cell can be different, facilitating flexible adjustment of the information indicated by the MC-DCI for each first cell.

[0038] 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.

[0039] 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. The singular forms "a," "an," and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include 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 or all possible combinations of one or more associated listed items.

[0040] 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 the same type of information from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first cell may also be referred to as the second cell, and similarly, the second cell may also be referred to as the first cell. 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".

[0041] 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."

[0042] Figure 1 This is a schematic flow chart illustrating a scheduling determination method according to an embodiment of the present disclosure. The scheduling determination method 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, and other communication devices. 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.

[0043] like Figure 1 As shown, the scheduling determination method may include the following steps:

[0044] In step S101, an association relationship corresponding to a first cell (Cell) is determined, wherein the association relationship includes an association relationship between a value of a carrier indicator field and a scheduling cell identifier, for determining whether the first cell is a cell scheduled by a second cell;

[0045] In step S102, the second cell receives downlink control information DCI for scheduling multiple cells, and determines a first value of a carrier indicator field (CIF) in the DCI;

[0046] In step S103, a scheduling cell identifier corresponding to the first value is determined according to the association relationship;

[0047] In step S104, it is determined whether the first cell is the DCI scheduled cell based on the relationship between the scheduling cell identifier corresponding to the first value and the identifier of the second cell (for example, the terminal can determine the identifier of the second cell based on system information).

[0048] In one embodiment, after receiving DCI for scheduling multiple cells (specifically, data for scheduling multiple cells) in the second cell, it is necessary to determine which cells the DCI is specifically for scheduling. For ease of description, DCI for scheduling multiple cells will be referred to as MC-DCI, where MC stands for multi-cell.

[0049] When the terminal determines whether the first cell is the cell scheduled by the MC-DCI, the terminal may make the determination based on a Radio Resource Control (RRC) message received in the first cell.

[0050] For example, the information element (IE) serving cell configuration (ServingCellConfig) in the RRC message is determined, and then the cross-carrier scheduling configuration (CrossCarrierSchedulingConfig) in the serving cell configuration is determined, and then the scheduling cell information (schedulingCellInfo) is determined in the cross-carrier scheduling configuration. Then, when the schedulingCellInfo indication value is other (other), the scheduling cell identifier (schedulingCellId) and the carrier indication field (cif-InScheduingCell) used in the scheduling cell are further determined in schedulingCellInfo. For different serving cells, in a multi-carrier scheduling scenario, the value of the carrier indication field used in the configured scheduling cell can be the same.

[0051] When the scheduling cell identifier configured in the RRC message is the same as the identifier of the second cell, and the value of the carrier indication field used in the scheduling cell configured in the RRC message is the same as the value of the 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.

[0052] When using MC-DCI to schedule multiple cells, if dynamic switching of the scheduled cells is not supported, the above method can configure the same association relationship for different scheduled cells, that is, the value of the carrier indication field in the association relationship of each scheduled cell is the same, and the scheduling cell identifier in the association relationship of each scheduled cell is the same, thereby realizing the indication of multiple cells (cell combinations) scheduled by MC-DCI.

[0053] However, when MC-DCI is used to schedule multiple cells, if dynamic switching of scheduled cells is supported, the scheduling flexibility of the above method is poor. This is because based on this method, the RRC message only carries a combination of a scheduling cell identifier and a carrier indicator field value used in the scheduling cell. Based on this RRC message, the terminal can only determine whether the first cell is scheduled by the MC-DCI sent by the cell corresponding to the scheduling cell identifier in the RRC message. When the CIF value in the MC-DCI is different from the value of the carrier indicator field used in the scheduling cell of the RRC message, or when the identifier of the scheduling cell (for example, the second cell where the MC-DCI is received) is different from the scheduling cell identifier in the RRC message, the first cell cannot be scheduled. In addition, if the scheduling cell switching is achieved by adjusting the CIF value in the MC-DCI, the multiple cells (cell combination) currently being scheduled will no longer be scheduled.

[0054] In an embodiment of the present disclosure, the network device can configure a corresponding association relationship for a serving cell (for example, a cell currently scheduled by MC-DCI or a cell that can be scheduled by MC-DCI). After the terminal receives an RRC message in the first cell in the serving cell, it determines that the RRC message contains the association relationship. Then, it can be determined that the association relationship in the RRC message is the association relationship corresponding to the first cell.

[0055] It should be noted that the terminal can receive RRC messages in multiple first cells, and each first cell can have its own corresponding association relationship. The association relationships corresponding to different first cells can be different or the same, and can be specifically configured as needed.

[0056] The association relationship may include the association relationship between the values ​​of multiple carrier indication fields and the scheduling cell identifier. In the RRC message, the value of the corresponding carrier indication field may be indicated by the cif-InScheduingCell field. The above association relationship may be carried in the RRC message, and the types in the RRC message include but are not limited to sequence, choice, etc. For example, it may be a sequence under an indication value "other" in schedulingCellInfo, or a sequence under multiple indication values ​​"other" in schedulingCellInfo.

[0057] The association relationship between the carrier indicator field and the scheduling cell identifier may include an association relationship between a value of a carrier indicator field and a scheduling cell identifier, for example, if the value of the carrier indicator field is 1, the corresponding scheduling cell identifier is 0;

[0058] The association relationship between the carrier indication field and the scheduling cell identifier may include an association relationship between the values ​​of multiple carrier indication fields and one scheduling cell identifier, for example, the value of the carrier indication field is 1, the corresponding scheduling cell identifier is 0, the value of the carrier indication field is 2, and the corresponding scheduling cell identifier is 0;

[0059] The association relationship between the above-mentioned carrier indication field and the scheduling cell identifier may include the association relationship between the values ​​of multiple carrier indication fields and multiple scheduling cell identifiers, for example, the value of the carrier indication field is 1, the corresponding scheduling cell identifier is 0, the value of the carrier indication field is 3, and the corresponding scheduling cell identifier is 2.

[0060] According to an embodiment of the present disclosure, an association relationship between the value of the carrier indicator field corresponding to each first cell and the scheduling cell identifier can be determined. Since the association relationship can define the 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, when a network device sends MC-DCI to a 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 combinations) to be scheduled.

[0061] For example, in the association relationship, if the value of the carrier indicator field is 1, the corresponding scheduling cell identifier is 0; if the value of the carrier indicator field is 2, the corresponding scheduling cell identifier is 0. Then, 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 can be scheduled. When the CIF value in the MC-DCI sent to the terminal in the second cell with the cell identifier 0 is 2, the first cell can also be scheduled. The CIF value can range from 0 to 7 and can, of course, be adjusted as needed.

[0062] For example, in the association relationship, the value of the carrier indicator field is 1, and the corresponding scheduling cell identifier is 0; the value of the carrier indicator field is 3, and the corresponding scheduling cell identifier is 2. Then, when the value of the CIF 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 can be scheduled; when the value of the CIF in the MC-DCI sent to the terminal in the second cell with the cell identifier 2 is 3, the first cell can also be scheduled.

[0063] Figure 2 FIG is a schematic flow chart of another scheduling determination method according to an embodiment of the present disclosure. Figure 2As shown, the determining whether the first cell is the DCI scheduled cell according to the relationship between the scheduling cell identifier corresponding to the first value and the identifier of the second cell includes:

[0064] In step S201, when the scheduling cell identifier corresponding to the first value is the same as the identifier of the second cell, it is determined that the first cell is the DCI-scheduled cell; and / or when the scheduling cell identifier corresponding to the first value is different from the identifier of the second cell, it is determined that the first cell is not the DCI-scheduled cell.

[0065] In one embodiment, after receiving MC-DCI in the second cell, the terminal may determine a value of the CIF in the MC-DCI, for example, called a first value, and further determine whether the first value exists according to the association relationship.

[0066] If the first value does not exist in the association relationship, it is determined that the first cell is not the MC-DCI scheduled cell (the scheduling cell identifier in the association relationship does not need to be considered); if the first value exists in the association relationship, but the scheduling cell identifier corresponding to the first value is different from the identifier of the second cell, it is determined that the first cell is not the MC-DCI scheduled cell; if the first value exists in the association relationship, and the scheduling cell identifier corresponding to the first value is the same as the identifier of the second cell, it is determined that the first cell is the MC-DCI scheduled cell.

[0067] In one embodiment, determining the association relationship corresponding to the first cell includes:

[0068] receiving a radio resource control (RRC) message in the first cell;

[0069] The association relationship is determined in the RRC message.

[0070] The network device may send an RRC message to the terminal in the first cell, and carry the association relationship corresponding to the first cell in the RRC message. After the terminal receives the RRC message in the first cell, when it is determined that the RRC message carries the association relationship (for example, the association relationship between the value of the carrier indication field included in the RRC message and the scheduling cell identifier), the association relationship in the RRC message may be determined as the association relationship corresponding to the first cell.

[0071] In one embodiment, the method further includes: determining an indication value of the scheduling cell information in the RRC message; wherein, when the indication value of the scheduling cell information is other, determining the association relationship in the RRC message.

[0072] The cross-carrier scheduling configuration of the RRC message received by the terminal in the first cell may include scheduling cell information schedulingCellInfo. The scheduling cell information may include multiple types of data, such as choice, sequence, Boolean, integer, floating point, etc., where the indication value of the "selection" type data may be own or other. In all embodiments of the present disclosure, the indication value of the scheduling cell information may refer to the indication value of the "selection" type data in the scheduling cell information.

[0073] When the scheduling cell information indicator value is "own", it means that the first cell can be scheduled by the DCI received by the terminal in the first cell, but not by the DCI received by the terminal in other cells (such as the second cell). It can be seen that in this case, the terminal has determined that the first cell is only scheduled by the DCI received by the terminal in the first cell, so the network device does not need to carry the association in the RRC message. Therefore, when the scheduling cell information indicator value is "own", the terminal does not need to determine the association for multi-cell scheduling in the RRC message.

[0074] When the indication value of the scheduling cell information is other (other), it means that the first cell can be scheduled by the DCI received by the terminal in other cells (cells other than the first cell) (cross-carrier scheduling). It can be seen that in this case, the terminal still needs to determine in which cell the DCI received by the terminal is scheduled by the first cell, so the network device can carry the association relationship in the RRC message for the terminal to determine whether the first cell is scheduled by the MC-DCI received by the terminal in the second cell. Also, when the indication value of the scheduling cell information is other, it is necessary for the terminal to determine the association relationship in the RRC message. The value of the carrier indication field in the association relationship can be the carrier indication field used in the scheduling cell in the scheduling cell information in the RRC message (which can be called

[0075] cif-InScheduingCell-r18).

[0076] Figure 3 It is a schematic diagram of an application scenario according to an embodiment of the present disclosure.

[0077] like Figure 3 As shown, it is taken as an example that the first cell includes Cell#1 (cell ID is 1) and Cell#2 (cell ID is 2), and the second cell includes Cell#0 (cell ID is 0).

[0078] The association relationship carried in the RRC message sent by the network device in 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.

[0079] Table 1-1 contains the association between the values ​​of multiple carrier indicator fields and multiple scheduled cell identifiers. For example, a carrier indicator field value of 1 corresponds to a scheduled cell identifier of 0; a carrier indicator field value of 2 corresponds to a scheduled cell identifier of 0; and a carrier indicator field value of 3 corresponds to a scheduled cell identifier of 2. It should be noted that within the same table, the values ​​of the carrier indicator field are all different.

[0080] Table 1-2 contains the association between the values ​​of multiple carrier indication fields and a scheduling cell identifier. The value of the carrier indication field is 1, and the corresponding scheduling cell identifier is 0. The value of the carrier indication field is 3, and the corresponding scheduling cell identifier is 0.

[0081] It should be noted that Figure 3 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.

[0082] When the terminal receives MC-DCI in Cell#0, if the terminal determines that the value of CIF in MC-DCI is 01 (i.e., 1), the terminal further determines that there is a carrier indication field with a value of 1 in table1-1, and then it can be determined that the scheduling cell identifier corresponding to the carrier indication field with a value of 1 in table1-1 is 0, which is the same as the identifier of Cell#0. Therefore, it can be determined that Cell#1 is the cell scheduled by the MC-DCI received by the terminal in Cell#0. The terminal determines that there is a carrier indication field with a value of 1 in table1-2, and then it can be determined that the scheduling cell identifier corresponding to the carrier indication field with a value of 1 in table1-2 is 0, which is the same as the identifier of Cell#0. Therefore, it can be determined that Cell#2 is the cell scheduled by the MC-DCI received by the terminal in Cell#0.

[0083] The network device can adjust the value of CIF in MC-DCI as needed, thereby adjusting the cell scheduled by MC-DCI. For example, the terminal determines that the value of CIF in MC-DCI is changed to 10 (i.e., 2). Further, the terminal determines that there is a carrier indication field with a value of 2 in table1-1, and then it can be determined that the scheduling cell identifier corresponding to the carrier indication field with a value of 2 in table1-1 is 0, which is the same as the identifier of Cell#0. Therefore, it can be determined that Cell#1 is the cell scheduled by the MC-DCI received by the terminal in Cell#0. If the terminal determines that there is no carrier indication field with a value of 1 in table1-2, then it can be determined that Cell#2 is not the cell scheduled by the MC-DCI received by the terminal in Cell#0.

[0084] The MC-DCI received by the terminal in Cell#0 can schedule cells other than Cell#0 as well as Cell#0. The terminal can select "own" or "other" based on the scheduling cell information in the cross-carrier scheduling configuration in the RRC message received from Cell#0. If "own" is selected, it can be determined that the MC-DCI can be used to schedule Cell#0 or is not scheduled by any cell. If the scheduling cell information indicates "other", it can be determined that Cell#0 is the scheduled cell and is scheduled by the DCI received by the terminal in cells other than Cell#0.

[0085] In one embodiment, when the terminal does not determine the association relationship in the RRC message received in the first cell, it can determine whether the first cell is scheduled by the second cell according to the legacy method, for example, determine whether the scheduling cell identifier in the scheduling cell information is the same as the identifier of the second cell. If they are the same, further determine whether the value of the carrier indication field used in the scheduling cell in the scheduling cell information is the same as the CIF value in the MC-DCI received in the second cell. If they are the same, it can be determined that the MC-DCI received in the second cell is used to schedule the first cell.

[0086] It should be noted that in all embodiments of the present disclosure, each element in the table 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.

[0087] In one implementation case, the network device may carry the association relationship to the terminal via the RRC message, may carry the association relationship to the terminal via other means, for example, it may be carried in a media access control control element (MAC CE), or may determine the association relationship in a predefined manner.

[0088] In the case where the association relationship is carried in an RRC message and sent to the terminal, it may be carried in the scheduling cell information (schedulingCellInfo-r18) of the RRC message. For example, in one embodiment, the content of the scheduling cell information may be as follows:

[0089]

[0090] When the scheduling cell information indication value is other (other), the sequence (sequence) may include n indication combinations, where n is an integer greater than 1, and each indication combination in the sequence includes a set of carrier indication field values ​​and scheduling cell identifiers, and n indication combinations (i.e., n carrier indication field values ​​and n scheduling cell identifiers) constitute the association relationship.

[0091] For terminals that do not support multi-cell scheduling, and terminals that support multi-cell scheduling, but when the received DCI is legacy DCI (for example, DCI used to schedule a single cell), after receiving the above-mentioned association relationship, these two terminals can determine the cell scheduled by the received legacy DCI based on the existing scheduling cell information (schedulingCellInfo), or they can determine the cell scheduled by the received legacy DCI based on the association relationship in the scheduling cell information (which can be called schedulingCellInfo-r18) in this embodiment.

[0092] When determining the cell scheduled by the received legacy DCI according to the association relationship in the scheduling cell information in this embodiment, the single cell scheduled by the received legacy DCI can be determined by the value of the carrier indication field in the preset indication combination and the scheduling cell identifier. For example, the single cell scheduled by the legacy DCI can be determined based on the value of the carrier indication field in the first indication combination and the scheduling cell identifier (cif-inSchedulingCell#1 and schedulingCellId#1).

[0093] In one embodiment, the scheduling cell information may include the following content:

[0094]

[0095] The scheduling cell information may include n others (other), and the sequence (sequence) in each other (other) may include 1 indication combination, which includes a set of carrier indication field values ​​and scheduling cell identifiers. The sequence indication combinations in the n others (that is, n carrier indication field values ​​and n scheduling cell identifiers) constitute the association relationship.

[0096] For terminals that do not support multi-cell scheduling, and terminals that support multi-cell scheduling, but when the received DCI is legacy DCI (for example, DCI used to schedule a single cell), after receiving the above-mentioned association relationship, these two terminals can determine the cell scheduled by the received legacy DCI based on the existing scheduling cell information (schedulingCellInfo), or they can determine the cell scheduled by the received legacy DCI based on the association relationship in the scheduling cell information (which can be called schedulingCellInfo-r18) in this embodiment.

[0097] When determining the cell scheduled by the received legacy DCI according to the association relationship in the scheduling cell information in this embodiment, the single cell scheduled by the received legacy DCI can be determined by the indication combination in the preset other indication value (including the value of the carrier indication field and the scheduling cell identifier). For example, the single cell scheduled by the received legacy DCI can be determined based on the value of the carrier indication field in the indication combination in the first other (other#1) and the scheduling cell identifier.

[0098] Figure 4 FIG. 1 is a schematic flow chart of another scheduling determination method according to an embodiment of the present disclosure. Figure 4 As shown, the method further includes:

[0099] In step S401, the size (i.e., the number of cells occupied) of the carrier indication field in the DCI is determined according to the value of the carrier indication field in the association relationship corresponding to the serving cell; wherein the serving cell is the cell currently scheduled by the DCI (for example, the first cell) or the serving cell in the cell that the DCI can schedule (which may include the first cell and cells other than the first cell), and the cells that the DCI can schedule can be defined in the form of a set.

[0100] In one embodiment, when the CIF size in the DCI is different, the terminal may parse the DCI in different ways. Therefore, the terminal needs to determine the size of the CIF in the MC-DCI received in the second cell in order to accurately parse the MC-DCI.

[0101] Since the carrier indication field can have multiple values ​​in the association relationship indicated by the network device to the terminal, the size of the CIF in the MC-DCI sent by the network device to the terminal needs to be sufficient to indicate the values ​​of all carrier indication fields. Therefore, the size of the CIF in the MC-DCI can be determined based on the range of values ​​of the carrier indication field in the association relationship corresponding to the serving cell. For example, the maximum value of the carrier indication field in the association relationship corresponding to the serving cell can be determined, and the size of the carrier indication field in the MC-DCI is determined based on the maximum value. For example, if the maximum value is 7, the size of the CIF in the MC-DCI can be determined to be 3 bits. For example, if the maximum value is 3, the size of the CIF in the MC-DCI can be determined to be 2 bits.

[0102] In one embodiment, determining the size of the carrier indication field in the DCI according to the value of the carrier indication field in the association relationship received in the serving cell includes:

[0103] When the range of values ​​of the carrier indication fields in the association relationship corresponding to the serving cells is the same, determining the size of the carrier indication field in the DCI according to the range of values ​​of the carrier indication field of the serving cell;

[0104] And / or when the range of the value of the carrier indication field in the association relationship corresponding to the serving cell is different, the size of the carrier indication field in the DCI is determined according to the maximum range of the value of the carrier indication field in the association relationship corresponding to the serving cell.

[0105] If the range of values ​​of the carrier indication field in the association relationship corresponding to the serving cells is the same and the maximum value of the carrier indication field in the association relationship corresponding to the serving cells is the same, then the size of the CIF in the MC-DCI can be determined based on the range of values ​​of the carrier indication field (e.g., the maximum value of the carrier indication field). For example, if the range is 0-3, the size of the CIF in the MC-DCI can be determined to be 2 bits; for example, if the range is 0-7, the size of the CIF in the MC-DCI can be determined to be 3 bits.

[0106] When the value ranges of the carrier indication field in the association relationship corresponding to the serving cell are different (e.g., partially different or completely different), the maximum value of the carrier indication field in the association relationship corresponding to the serving cell may be different. In this case, it is necessary to determine the maximum range of the value of the carrier indication field in the association relationship corresponding to the serving cell, and then determine the size of the CIF in the MC-DCI based on the maximum range. For example, if the range in the association relationship corresponding to cell 1 is 0-3, the range in the association relationship corresponding to cell 2 is 0-7, and the maximum range is 0-7, then the size of the CIF in the MC-DCI can be determined to be 3 bits.

[0107] Figure 5 This is a schematic flow chart illustrating a method for determining an indication according to an embodiment of the present disclosure. The method for determining an indication 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.

[0108] like Figure 5 As shown, the indication determination method may include the following steps:

[0109] In step S501, an association relationship corresponding to a first cell is determined, wherein the association relationship includes an association relationship between a value of a first information field and information indicated by the first information field for the first cell;

[0110] In step S502, downlink control information DCI for scheduling multiple cells is received in the second cell, and a value of the first information field in the DCI is determined;

[0111] In step S503, in a case where the DCI schedules the first cell, information indicated by the first information field in the DCI for the first cell is determined according to the association relationship.

[0112] In one embodiment, the first information field includes but is not limited to BWP (Bandwidth part) indicator, TDRA (Time Domain Resource Assignment), FDRA (Frequency Domain Resource Assignment), ZP CSI-RS trigger (Zero Power Channel State Information Reference Signal Trigger), Downlink assignment index, PUCCH resource indicator, PDSCH-to-HARQ feedback timing indicator, Antenna port(s), Transmission configuration indication, SRS request, and DMRS sequence initialization.

[0113] The following mainly takes the BWP indicator information field as an example to exemplify the technical solution of the present disclosure.

[0114] In one embodiment, when multiple cells are scheduled via MC-DCI, the information field in the MC-DCI also needs to indicate each of the multiple cells. For example, if a terminal receives MC-DCI in the second cell, Cell#0, and the first cells scheduled by the MC-DCI include Cell#1 and Cell#2, then it is necessary to determine the information indicated by the information field in the MC-DCI for Cell#1 and the information indicated for Cell#2. For example, for the BWP indicator in the MC-DCI, it is necessary to determine the BWP identifier indicated by the BWP indicator for Cell#1 and the BWP identifier indicated for Cell#2.

[0115] In an embodiment of the present disclosure, the network device can configure a corresponding association relationship for a serving cell (for example, a cell currently scheduled by MC-DCI or a cell that can be scheduled by MC-DCI). For example, after the terminal receives an RRC message in the first cell in the serving cell, it determines that the RRC message contains the association relationship. Then, it can be determined that the association relationship in the RRC message is the association relationship corresponding to the first cell.

[0116] It should be noted that the terminal can receive RRC messages in multiple first cells, and each first cell can have its own corresponding association relationship. The association relationships corresponding to different first cells can be different or the same, and can be specifically configured as needed.

[0117] The association relationship between the first information field and the information indicated by the first information field for the first cell may include an association relationship between the value of the first information field and the information indicated by the first information field for the first cell, which may be carried in an RRC message.

[0118] The association relationship between the first information field and the information indicated by the first information field for the first cell may include an association relationship between a value of the first information field and the information indicated by the first information field for the first cell, for example, the value of the first information field is 1, and the indication information is that the BWP identifier is 3;

[0119] The association relationship between the above-mentioned first information field and the information indicated by the first information field for the first cell may include the association relationship between the values ​​of multiple first information fields and the information indicated by multiple first information fields for the first cell, for example, the value of the first information field is 0, the indication information is BWP identification is 2, the value of the first information field is 1, and the indication information is BWP identification is 3.

[0120] According to an embodiment of the present disclosure, an association relationship between the value of the first information field corresponding to each first cell and the information indicated by the first information field for the first cell can be determined. Furthermore, after receiving MC-DCI in the second cell, the terminal can determine the information indicated by the information field in the MC-DCI for each first cell based on the association relationship. Because the association relationship is configured separately for each first cell, the association relationship corresponding to each first cell can be different, facilitating flexible adjustment of the information indicated by the MC-DCI for each first cell.

[0121] In one embodiment, determining the association relationship corresponding to the first cell includes:

[0122] receiving a radio resource control (RRC) message in the first cell;

[0123] The association relationship is determined in the RRC message.

[0124] The network device may send an RRC message to the terminal in the first cell, and carry the association relationship corresponding to the first cell in the RRC message. After the terminal receives the RRC message in the first cell, when it is determined that the RRC message carries the association relationship (for example, an association relationship between the value of the first information field included in the RRC message and the information indicated by the first information field for the first cell), the association relationship in the RRC message may be determined as the association relationship corresponding to the first cell.

[0125] Figure 6A It is a schematic diagram of an application scenario according to an embodiment of the present disclosure. Figure 6B It is a schematic diagram of another application scenario according to an embodiment of the present disclosure.

[0126] like Figure 6A As shown, it is taken as an example that the first cell includes Cell#1 (cell identifier is 1) and Cell#2 (cell identifier is 2), the second cell includes Cell#0 (cell identifier is 0), and the first information field includes the BWP indicator.

[0127] The terminal determines that the MC-DCI received in Cell#0 schedules the first cell Cell#1 and Cell#2, and also schedules the second cell Cell#0. The network device carries the association relationship table 2-0 in the RRC message sent from Cell#0 to the terminal, the association relationship carried in the RRC message sent from Cell#1 to the terminal is table 2-1, and the association relationship carried in the RRC message sent from Cell#2 to the terminal is table 2-2.

[0128] Table 2-0, table 2-1, and table 2-2 contain associations between values ​​of multiple first information fields and information indicated by the multiple first information fields for the first cell. For example, in table 2-1, the value of the BWP indicator in the MC-DCI is 00, and the information indicated is that the BWP ID is 2; the value of the BWP indicator in the MC-DCI is 01, and the information indicated is that the BWP ID is 3; the value of the BWP indicator in the MC-DCI is 10, and the information indicated is that the BWP ID is 2; the value of the BWPindicator in the MC-DCI is 11, and the information indicated is that the BWP ID is 10.

[0129] When the terminal receives MC-DCI in Cell#0, if the terminal determines that the value of the BWP indicator in the MC-DCI is 01 (that is, 1), the terminal further determines that there is a BWP indicator with a value of 1 in table2-0, and then it can be determined that the information indicated by the BWP indicator with a value of 1 in table2-0 is BWP ID 2, thereby determining that the BWP ID indicated by the MC-DCI for Cell#0 is 2; the terminal determines that there is a BWP indicator with a value of 1 in table2-1, and then it can be determined that the information indicated by the BWP indicator with a value of 1 in table2-1 is BWP ID 3, thereby determining that the BWP ID indicated by the MC-DCI for Cell#1 is 3; the terminal can determine that there is a BWP indicator with a value of 1 in table2-2, and then it can be determined that the information indicated by the BWP indicator with a value of 1 in table2-2 is BWP ID 1, thereby determining that the BWP ID indicated by the MC-DCI for Cell#2 is 1.

[0130] like Figure 6B As shown, it is taken as an example that the first cell includes Cell#1 (cell ID is 1) and Cell#2 (cell ID is 2), the second cell includes Cell#0 (cell ID is 0), and the first information field includes a ZP CSI-RS trigger.

[0131] The terminal determines that the MC-DCI received in Cell#0 schedules the first cell Cell#1 and Cell#2, and also schedules the second cell Cell#0. The network device carries the association relationship table 3-0 in the RRC message sent by Cell#0 to the terminal, carries the association relationship table 3-1 in the RRC message sent by Cell#1 to the terminal, and does not carry the association relationship in the RRC message sent by Cell#2 to the terminal, or carries the association relationship table 3-2, but table 3-2 is blank, indicating that the corresponding BWP is not configured.

[0132] Table 3-0 and Table 3-1 contain associations between values ​​of multiple first information fields and information indicated by the multiple first information fields for the first cell. For example, in Table 3-1, the value of the ZP CSI-RS trigger in the MC-DCI is 00, indicating that the information is reserved; the value of the ZP CSI-RS trigger in the MC-DCI is 01, indicating that the ZP CSI-RS resource set ID is 1.

[0133] When the terminal receives MC-DCI in Cell#0, if the terminal determines that the value of the ZP CSI-RS trigger in the MC-DCI is 01 (i.e., 1), the terminal further determines that there is a ZP CSI-RS trigger with a value of 1 in table3-0, and then it can be determined that the information indicated by the ZP CSI-RS trigger with a value of 1 in table3-0 is that the ZP CSI-RS resource set ID is reserved, thereby determining that the ZP CSI-RS resource set ID indicated by the MC-DCI for Cell#0 is reserved; the terminal determines that there is a ZP CSI-RS trigger with a value of 1 in table3-1, and then it can be determined that the information indicated by the ZP CSI-RS trigger with a value of 1 in table3-1 is that the ZP CSI-RS resource set ID is 1, thereby determining that the ZP CSI-RS resource set ID indicated by the MC-DCI for Cell#1 is 1.

[0134] It should be noted that in Figure 6A and Figure 6B In the table, the values ​​of the first information field are arranged from 00 to 11. However, in specific applications, the arrangement of the values ​​of the first information field in the table can be set as needed, for example, it can be set from 11 to 00, or it is not monotonically increasing or decreasing from top to bottom, for example, it can be set to 10, 01, 00, 11 from top to bottom.

[0135] In one implementation case, the network device may carry the association relationship through the RRC message and send it to the terminal, or may carry the association relationship through other means, for example, may carry it in a MAC CE and send it to the terminal.

[0136] In the case where the association relationship is carried in an RRC message and sent to the terminal, taking the BWP indicator as the first information as an example, the RRC message may include n indication combinations, where n is an integer greater than 1, and each indication combination contains a set of BWPindicator values ​​and BWP IDs. The n indication combinations (that is, n BWP indicator values ​​and BWP IDs) constitute the association relationship.

[0137] For terminals that do not support multi-cell scheduling, and terminals that support multi-cell scheduling, but when the received DCI is legacy DCI (for example, DCI used to schedule a single cell), after receiving the above-mentioned association relationship, these two terminals can determine the BWP ID indicated by the BWP indicator in the received DCI for the first cell based on the value of the BWP indicator in the preset indication group and the BWP ID. For example, the BWP ID indicated by the BWP indicator in the received DCI for the first cell can be determined based on the value of the BWP indicator in the first indication group and the BWP ID.

[0138] It should be noted that, when the terminal does not receive the association relationship in the RRC messages received in all cells scheduled by MC-DCI, the information indicated by the first information field for the first cell can be determined according to a legacy method.

[0139] The information indicated by the first information field for the first cell may also be determined in other ways, for example, it may be determined based on the configuration of the reference cell, for example, it may be determined based on the configuration parameters related to the first information field in the RRC message received in the first cell and the value of the first information field in the MC-DCI.

[0140] The reference cell may be determined according to a predefined rule, for example, the second cell, or the cell with the largest or smallest cell identifier among the cells currently scheduled by MC-DCI or among the cells that can be scheduled.

[0141] Taking the second cell as a reference cell as an example, the first information field is exemplified as a BWP indicator, and the configuration parameter related to the first information field is the number of BWPs.

[0142] When the terminal does not determine the association relationship in the RRC messages received from all cells scheduled by MC-DCI, it can first determine the information indicated by the first information field for the reference cell. For example, the value of the BWP indicator in the first information field is 11, and the information indicated for the second cell (e.g., cell 0) is BWP ID 4.

[0143] Then, the configuration parameters related to the first information field in the RRC message received in each first cell can be determined, and then the information indicated by the first information field in the MC-DCI for the first cell can be determined based on the configuration parameters related to the first information field in the RRC message received in the first cell and the value of the first information field in the MC-DCI.

[0144] If the configuration parameter related to the first information field in the RRC message received in the first cell is greater than or equal to the range of values ​​of the information indicated by the first information field for the reference cell, then it can be determined that the information indicated by the first information field in the MC-DCI for the first cell is the same as the information indicated for the reference cell; for example, cell 1 is the first cell scheduled by MC-DCI, and the number of BWPs configured in the RRC message received in cell 1 is greater than or equal to 4, then it can be determined that the information indicated by the BWPindicator in the MC-DCI for cell 1 is the same as the information indicated for cell 0, that is, the information indicated for cell 1 is also BWP ID 4.

[0145] If the configuration parameter related to the first information field in the RRC message received in the first cell is less than the value of the information indicated by the first information field for the reference cell, then it can be determined that the first information field in the MC-DCI does not indicate the first cell, or it can be determined that the value of the information indicated by the first information field in the MC-DCI for the first cell is equal to the maximum value of the configuration parameter related to the first information field in the RRC message received in the first cell. For example, if cell 2 is the first cell scheduled by MC-DCI, and the number of BWPs configured in the RRC message received in cell 2 is equal to 2 (the maximum value is 2), then it can be determined that the BWP indicator in the MC-DCI does not indicate cell 2, or it can be determined that the information indicated by the BWPindicator in the MC-DCI for cell 2 is BWP ID 2.

[0146] Figure 7 FIG6 is a schematic flow chart of another scheduling determination method according to an embodiment of the present disclosure. As shown in FIG6 , the method further includes:

[0147] In step S701, the size (i.e., the number of cells occupied) of the first information field in the DCI is determined according to the value of the first information field in the association relationship corresponding to the serving cell; wherein the serving cell is the cell currently scheduled by the DCI (for example, the first cell) or the serving cell in the cell that the DCI can schedule (which may include cells other than the first cell), and the cells that the DCI can schedule can be defined in the form of a set.

[0148] In one embodiment, for the first information field in the DCI, different sizes may result in different parsing methods of the terminal. Therefore, the terminal needs to determine the size of the first information field in the MC-DCI received in the second cell to accurately parse the information.

[0149] Since the first information field in the association indicated by the network device to the terminal can have multiple values, the size of the first information field in the MC-DCI sent by the network device to the terminal needs to be sufficient to indicate the values ​​of all the first information fields of the association. Therefore, the size of the CIF in the MC-DCI can be determined based on the range of values ​​of the first information field in the association corresponding to the serving cell. For example, the maximum value of the first information field in the association corresponding to the serving cell can be determined, and the size of the carrier indication field in the MC-DCI can be determined based on the maximum value. For example, if the maximum value is 1, the size of the CIF in the MC-DCI can be determined to be 1 bit. For example, if the maximum value is 3, the size of the CIF in the MC-DCI can be determined to be 2 bits.

[0150] In one embodiment, determining the size of the first information field in the DCI according to the value of the first information field in the association relationship received in the serving cell includes:

[0151] When the range of the value of the first information field in the association relationship corresponding to the serving cell is the same, determining the size of the first information field in the DCI according to the range of the value of the first information field of the serving cell;

[0152] And / or when the range of the value of the first information field in the association relationship corresponding to the serving cell is different, the size of the first information field in the DCI is determined according to the maximum range of the value of the first information field in the association relationship corresponding to the serving cell.

[0153] If the range of values ​​of the first information field in the association relationship corresponding to the serving cells is the same and the maximum value of the first information field in the association relationship corresponding to the serving cells is the same, the size of the CIF in the MC-DCI can be determined based on the range of values ​​of the first information field (e.g., the maximum value of the first information field). For example, if the range is 0-1, the size of the first information field in the MC-DCI can be determined to be 1 bit; if the range is 0-3, the size of the first information field in the MC-DCI can be determined to be 2 bits.

[0154] If the range of values ​​of the first information field in the association relationship corresponding to the serving cells is different, the maximum value of the first information field in the association relationship corresponding to the serving cells may be different. In this case, it is necessary to determine the maximum range of values ​​of the first information field in the association relationship corresponding to the serving cells, and then determine the size of the first information field in the MC-DCI based on the maximum range. For example, if the range in the association relationship corresponding to cell 1 is 0-1, and the range in the association relationship corresponding to cell 2 is 0-3, and the maximum range is 0-3, then the size of the CIF in the MC-DCI can be determined to be 2 bits.

[0155] Figure 8 The present invention is a schematic flow chart of a method for indicating an association relationship according to an embodiment of the present disclosure. The method for indicating an association relationship 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 mobile phones, tablet computers, wearable devices, sensors, Internet of Things devices, and other communication devices.

[0156] like Figure 8 As shown, the association relationship indication method may include the following steps:

[0157] In step S801, an association relationship corresponding to a first cell is indicated to a terminal, wherein the association relationship includes an association relationship between a value of a carrier indicator field and a scheduling cell identifier.

[0158] In an embodiment of the present disclosure, the network device can configure a corresponding association relationship for a serving cell (for example, a cell currently scheduled by MC-DCI or a cell that can be scheduled by MC-DCI). After the terminal receives an RRC message in the first cell in the serving cell, it determines that the RRC message contains the association relationship. Then, it can be determined that the association relationship in the RRC message is the association relationship corresponding to the first cell.

[0159] It should be noted that the network device can send RRC messages to the terminal in multiple first cells, and each first cell can have its own corresponding association relationship. The association relationships corresponding to different first cells can be different or the same, and can be configured as needed.

[0160] The association relationship may include the association relationship between the values ​​of multiple carrier indication fields and the scheduling cell identifier. In the RRC message, the value of the corresponding carrier indication field may be indicated by the cif-InScheduingCell field. The above association relationship may be carried in the RRC message, and the types in the RRC message include but are not limited to sequence, choice, etc. For example, it may be a sequence under an indication value "other" in schedulingCellInfo, or a sequence under multiple indication values ​​"other" in schedulingCellInfo.

[0161] The association relationship between the carrier indicator field and the scheduling cell identifier may include an association relationship between a value of a carrier indicator field and a scheduling cell identifier, for example, if the value of the carrier indicator field is 1, the corresponding scheduling cell identifier is 0;

[0162] The association relation between the carrier indicator field and the scheduling cell identifier may include an association relation between the values ​​of multiple carrier indicator fields and one scheduling cell identifier, for example, if the value of the carrier indicator field is 1, the corresponding scheduling cell identifier is 0; if the value of the carrier indicator field is 2, the corresponding scheduling cell identifier is 0;

[0163] The association relationship between the above-mentioned carrier indication field and the scheduling cell identifier may include the association relationship between the values ​​of multiple carrier indication fields and multiple scheduling cell identifiers, for example, the value of the carrier indication field is 1, the corresponding scheduling cell identifier is 0, the value of the carrier indication field is 3, and the corresponding scheduling cell identifier is 2.

[0164] According to an embodiment of the present disclosure, a network device can determine the association relationship between the value of the carrier indication field corresponding to each first cell and the scheduling cell identifier, and indicate the association relationship to the terminal. Since 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 the association of the value of one carrier indication field with one scheduling cell identifier, when the subsequent network device sends MC-DCI to the terminal according to 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 according to the association relationship corresponding to the first cell to be scheduled, thereby dynamically adjusting the multiple cells (cell combinations) to be scheduled.

[0165] For example, in the association relationship, the value of the carrier indicator field is 1, and the corresponding scheduling cell identifier is 0; the value of the carrier indicator field is 2, and the corresponding scheduling cell identifier is 0. Then, when the value of the CIF 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 can be scheduled; when the value of the CIF in the MC-DCI sent by the network device to the terminal in the second cell with the cell identifier 0 is 2, the first cell can also be scheduled.

[0166] For example, in the association relationship, the value of the carrier indicator field is 1, and the corresponding scheduling cell identifier is 0; the value of the carrier indicator field is 3, and the corresponding scheduling cell identifier is 2. Then, when the value of the CIF 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 can be scheduled; when the value of the CIF in the MC-DCI sent to the terminal in the second cell with the cell identifier 2 is 3, the first cell can also be scheduled.

[0167] Figure 9 FIG. 1 is a schematic flow chart of another method for indicating an association relationship according to an embodiment of the present disclosure. Figure 9 As shown, the method further includes:

[0168] In step S901, it is determined that the first cell is scheduled through the DCI for scheduling multiple cells sent by the second cell, and a first value of a carrier indicator field corresponding to the identifier of the second cell is determined according to the association relationship;

[0169] In step S902, the DCI is sent to the terminal in the second cell, wherein the value of the indication field in the DCI is equal to the first value.

[0170] In one embodiment, after the network device indicates the association relationship to the terminal, when it is necessary to schedule the first cell by sending MC-DCI in the second cell, the network device can determine the first value of the carrier indicator field corresponding to the identifier of the second cell based on the association relationship, and then in the MC-DCI sent by the second cell to the terminal, the value of the CIF in the MC-DCI can be set equal to the first value. After the terminal receives the MC-DCI in the second cell, it can determine that the scheduling cell identifier corresponding to the first value of the CIF in the MC-DCI in the association relationship is the same as the identifier of the second cell, thereby determining that the first cell is the cell scheduled by the MC-DCI.

[0171] In one embodiment, sending the association relationship corresponding to the first cell to the terminal includes: sending an RRC message to the terminal in the first cell, wherein the RRC message carries the association relationship.

[0172] The network device may send an RRC message to the terminal in the first cell, and carry the association relationship corresponding to the first cell in the RRC message. After the terminal receives the RRC message in the first cell, when it is determined that the RRC message carries the association relationship (for example, the association relationship between the value of the carrier indication field included in the RRC message and the scheduling cell identifier), the association relationship in the RRC message may be determined as the association relationship corresponding to the first cell.

[0173] In one embodiment, the method further includes: determining an indication value of the scheduling cell information in the RRC message; wherein, when the indication value of the scheduling cell information is other, carrying the association relationship in the RRC message.

[0174] The cross-carrier scheduling configuration of the RRC message sent by the network device to the terminal in the first cell may include scheduling cell information, and the scheduling cell information may include multiple types of data, such as choice, sequence, Boolean, integer, floating point, etc., wherein the indication value of the "selection" type data may be self (own) or other (other). In all embodiments of the present disclosure, the indication value of the scheduling cell information may refer to the indication value of the "selection" type data in the scheduling cell information.

[0175] When the scheduling cell information indicator value is "own," it indicates that the first cell can be scheduled by DCI sent by the first cell, but not by DCI sent by other cells (e.g., the second cell). Therefore, in this case, it has been determined that the first cell is scheduled only by DCI received by the terminal in the first cell. Therefore, the network device does not need to carry the multi-cell scheduling association in the RRC message.

[0176] When the indication value of the scheduling cell information is other (other), it means that the first cell can be scheduled by the DCI sent by other cells (cross-carrier scheduling). It can be seen that in this case, the terminal still needs to determine in which cell the DCI received by the terminal is scheduled by the first cell, so the network device can carry the association relationship in the RRC message for the terminal to determine whether the first cell is scheduled by the MC-DCI received by the terminal in the second cell. The value of the carrier indication field in the association relationship can be the value of the carrier indication field (which can be called cif-InScheduingCell-r18) used in the scheduling cell in the scheduling cell information in the RRC message.

[0177] In one embodiment, the method further includes: determining the size of the carrier indication field in the DCI based on the value of the carrier indication field in the association relationship corresponding to the serving cell; wherein the serving cell includes the cell currently scheduled by the DCI or the cell that can be scheduled by the DCI, and the cell that can be scheduled by the DCI can be defined in the form of a set.

[0178] In one embodiment, for the CIF in the DCI, different sizes may result in different parsing methods of the terminal. Therefore, the terminal needs to determine the size of the CIF in the MC-DCI received in the second cell in order to accurately parse it.

[0179] Since the carrier indication field can have multiple values ​​in the association relationship indicated by the network device to the terminal, the size of the CIF in the MC-DCI sent by the network device to the terminal needs to be sufficient to indicate the values ​​of all carrier indication fields. Therefore, the size of the CIF in the MC-DCI can be determined based on the value of the carrier indication field in the association relationship corresponding to the serving cell. For example, the maximum value of the carrier indication field in the association relationship corresponding to the serving cell can be determined, and the size of the carrier indication field in the MC-DCI is determined based on the maximum value. For example, if the maximum value is 7, the size of the CIF in the MC-DCI can be determined to be 3 bits. For example, if the maximum value is 3, the size of the CIF in the MC-DCI can be determined to be 2 bits.

[0180] In one embodiment, determining the size of the carrier indication field in the DCI according to the value of the carrier indication field in the association relationship received in the serving cell includes:

[0181] When the range of values ​​of the carrier indication fields in the association relationship corresponding to the serving cells is the same, determining the size of the carrier indication field in the DCI according to the range of values ​​of the carrier indication field;

[0182] And / or when the range of the value of the carrier indication field in the association relationship corresponding to the serving cell is different, the size of the carrier indication field in the DCI is determined according to the maximum range of the value of the carrier indication field in the association relationship corresponding to the serving cell.

[0183] If the range of values ​​of the carrier indication field in the association relationship corresponding to the serving cells is the same and the maximum value of the carrier indication field in the association relationship corresponding to the serving cells is the same, then the size of the CIF in the MC-DCI can be determined based on the range of values ​​of the carrier indication field (e.g., the maximum value of the carrier indication field). For example, if the range is 0-3, the size of the CIF in the MC-DCI can be determined to be 2 bits; for example, if the range is 0-7, the size of the CIF in the MC-DCI can be determined to be 3 bits.

[0184] If the range of values ​​of the carrier indicator field in the association relationship corresponding to the serving cell is different, the maximum value of the carrier indicator field in the association relationship corresponding to the serving cell may be different. In this case, it is necessary to determine the maximum range of values ​​of the carrier indicator field in the association relationship corresponding to the serving cell, and then determine the size of the CIF in the MC-DCI based on the maximum range. For example, if the range in the association relationship corresponding to cell 1 is 0-3, the range in the association relationship corresponding to cell 2 is 0-7, and the maximum range is 0-7, then the size of the CIF in the MC-DCI can be determined to be 3 bits.

[0185] Figure 10 The present invention is a schematic flow chart of a method for indicating an association relationship according to an embodiment of the present disclosure. The method for indicating an association relationship 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 mobile phones, tablet computers, wearable devices, sensors, Internet of Things devices, and other communication devices.

[0186] like Figure 10 As shown, the association relationship indication method may include the following steps:

[0187] In step S1001, an association relationship corresponding to a first cell is indicated to a terminal, wherein the association relationship includes an association relationship between a value of a first information field and information indicated by the first information field for the first cell.

[0188] In one embodiment, when multiple cells are scheduled via MC-DCI, the information field in the MC-DCI also needs to indicate each of the multiple cells. For example, if the second cell, Cell#0, sends MC-DCI to the terminal, and the first cells used by the MC-DCI for scheduling include Cell#1 and Cell#2, then it is necessary to determine the information indicated by the information field in the MC-DCI for Cell#1 and the information indicated for Cell#2. For example, for the BWP indicator in the MC-DCI, it is necessary to determine the BWP identifier indicated by the BWP indicator for Cell#1 and the BWP identifier indicated for Cell#2.

[0189] In an embodiment of the present disclosure, the network device can configure a corresponding association relationship for a serving cell (for example, a cell currently scheduled by MC-DCI or a cell that can be scheduled by MC-DCI). For example, after the terminal receives an RRC message in the first cell in the serving cell, it determines that the RRC message contains the association relationship. Then, it can be determined that the association relationship in the RRC message is the association relationship corresponding to the first cell.

[0190] It should be noted that the terminal can receive RRC messages in multiple first cells, and each first cell can have its own corresponding association relationship. The association relationships corresponding to different first cells can be different or the same, and can be specifically configured as needed.

[0191] The association relationship between the above-mentioned first information field and the information indicated by the first information field for the first cell may include an association relationship between the value of the first information field and the information indicated by the first information field for the first cell, which may be carried in the RRC message in the form of a table.

[0192] The association relationship between the first information field and the information indicated by the first information field for the first cell may include an association relationship between a value of the first information field and the information indicated by the first information field for the first cell, for example, the value of the first information field is 1, and the indication information is that the BWP identifier is 3;

[0193] The association relationship between the above-mentioned first information field and the information indicated by the first information field for the first cell may include the association relationship between the values ​​of multiple first information fields and the information indicated by multiple first information fields for the first cell, for example, the value of the first information field is 0, the indication information is BWP identification is 2, the value of the first information field is 1, and the indication information is BWP identification is 3.

[0194] According to an embodiment of the present disclosure, a network device can determine an association relationship between the value of the first information field corresponding to each first cell and the information indicated by the first information field for the first cell, and indicate the association relationship to a terminal, so that after the terminal receives MC-DCI in a second cell, it can determine the information indicated by the information field in the MC-DCI for each first cell based on the association relationship. Because the association relationship is configured separately for each first cell, the association relationship corresponding to each first cell can be different, facilitating flexible adjustment of the information indicated by the MC-DCI for each first cell.

[0195] Figure 11 FIG. 1 is a schematic flow chart of another method for indicating an association relationship according to an embodiment of the present disclosure. Figure 11 As shown, the method further includes:

[0196] In step S1101, first information indicated by a first information field in a DCI for scheduling multiple cells sent by a second cell for the first cell is determined, and a value of a first information field corresponding to the first information is determined according to the association relationship;

[0197] In step S1102, the DCI is sent to the terminal in the second cell, wherein the value of the first information field in the DCI is equal to the value of the first information field corresponding to the first information in the association relationship.

[0198] In one embodiment, after the network device indicates the association relationship to the terminal, when it is necessary to indicate first information for the first cell through the first information field, the value of the first information field corresponding to the first information can be determined based on the association relationship. Then, in the MC-DCI sent by the second cell to the terminal, the value of the first information field in the MC-DCI can be set equal to the value of the first information field corresponding to the first information in the association relationship. After the terminal receives the MC-DCI in the second cell, it can determine that the value of the first information field in the MC-DCI corresponds to the first information in the association relationship, thereby determining that the information indicated by the first information field in the MC-DCI for the first cell is the first information.

[0199] In one embodiment, the method further includes: determining the size of the first information field in the DCI based on the value of the first information field in the association relationship corresponding to the serving cell; wherein the serving cell includes the cell currently scheduled by the DCI or the cell that can be scheduled by the DCI, and the cell that can be scheduled by the DCI can be defined in the form of a set.

[0200] In one embodiment, for the first information field in the DCI, different sizes may result in different parsing methods of the terminal. Therefore, the terminal needs to determine the size of the first information field in the MC-DCI received in the second cell to accurately parse the information.

[0201] Since the first information field in the association indicated by the network device to the terminal can have multiple values, the size of the first information field in the MC-DCI sent by the network device to the terminal needs to be sufficient to indicate the values ​​of all the first information fields of the association. Therefore, the size of the CIF in the MC-DCI can be determined based on the range of values ​​of the first information field in the association corresponding to the serving cell. For example, the maximum value of the first information field in the association corresponding to the serving cell can be determined, and the size of the carrier indication field in the MC-DCI can be determined based on the maximum value. For example, if the maximum value is 1, the size of the CIF in the MC-DCI can be determined to be 1 bit. For example, if the maximum value is 3, the size of the CIF in the MC-DCI can be determined to be 2 bits.

[0202] In one embodiment, determining the size of the first information field in the DCI according to the value of the first information field in the association relationship received in the serving cell includes:

[0203] When the range of the value of the first information field in the association relationship corresponding to the serving cell is the same, determining the size of the first information field in the DCI according to the range of the value of the first information field of the serving cell;

[0204] And / or when the range of the value of the first information field in the association relationship corresponding to the serving cell is different, the size of the first information field in the DCI is determined according to the maximum range of the value of the first information field in the association relationship corresponding to the serving cell.

[0205] If the range of values ​​of the first information field in the association relationship corresponding to the serving cells is the same and the maximum value of the first information field in the association relationship corresponding to the serving cells is the same, the size of the CIF in the MC-DCI can be determined based on the range of values ​​of the first information field (e.g., the maximum value of the first information field). For example, if the range is 0-1, the size of the first information field in the MC-DCI can be determined to be 1 bit; if the range is 0-3, the size of the first information field in the MC-DCI can be determined to be 2 bits.

[0206] If the range of values ​​of the first information field in the association relationship corresponding to the serving cells is different, the maximum value of the first information field in the association relationship corresponding to the serving cells may be different. In this case, it is necessary to determine the maximum range of values ​​of the first information field in the association relationship corresponding to the serving cells, and then determine the size of the first information field in the MC-DCI based on the maximum range. For example, if the range in the association relationship corresponding to cell 1 is 0-1, and the range in the association relationship corresponding to cell 2 is 0-3, and the maximum range is 0-3, then the size of the CIF in the MC-DCI can be determined to be 2 bits.

[0207] In one embodiment, sending the association relationship corresponding to the first cell to the terminal includes: sending an RRC message to the terminal in the first cell, wherein the RRC message carries the association relationship.

[0208] The network device may send an RRC message to the terminal in the first cell, and carry the association relationship corresponding to the first cell in the RRC message. After the terminal receives the RRC message in the first cell, when it is determined that the RRC message carries the association relationship (for example, a table containing an association relationship between a value of a first information field and information indicated by the first information field for the first cell in the RRC message), the association relationship in the RRC message may be determined as the association relationship corresponding to the first cell.
