Description

[0001] This application is based on a Chinese patent application, application number PCT / CN2022 / 101654, filed on June 27, 2022. Priority to the aforementioned Chinese patent application is claimed, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of communication technology, and more specifically, to scheduling determination method, indication determination method, association relationship indication method, scheduling determination device, indication determination device, association relationship indication device, communication device, and computer-readable storage medium.

[0016] According to an eleventh aspect of the present disclosure, an association relationship indication device is provided, the device comprising: a sending module configured to indicate to a terminal a relationship set corresponding to a first cell, wherein the relationship set includes the association relationship between the value of a first information field and the information indicated by the first information field for the first cell.

[0017] According to a twelfth aspect of the present disclosure, an association relationship indication device is provided, executed by a network device, the device comprising: a sending module configured to indicate to a terminal a relationship set corresponding to a first cell, wherein the relationship set includes the association relationship between the value of a first information field and the information indicated by the first information field for the first cell.

[0018] According to a thirteenth aspect of the present disclosure, a communication device is provided, comprising: a processor; a memory for storing a computer program; wherein, when the computer program is executed by the processor, the above-described scheduling determination method and / or the above-described instruction determination method are implemented.

Then, after the terminal receives the MC-DCI in the second cell, it can determine the information indicated by the information field in the MC-DCI for each first cell based on the association. Since the relationship set is allocated and configured for each first cell, the relationship set corresponding to each first cell can be different, facilitating flexible adjustment of the information indicated by the MC-DCI for each first cell.

[0047] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0048] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0049] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of embodiments of this disclosure, a first cell may also be referred to as a second cell, and similarly, a second cell may also be referred to as a first cell. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination."

[0050] For the sake of brevity and ease of understanding, this document uses the terms "greater than" or "less than", "higher than" or "lower than" to describe size relationships. However, it will be understood by those skilled in the art that the term "greater than" also includes the meaning of "greater than or equal to", and "less than" also includes the meaning of "less than or equal to"; the term "higher than" also includes the meaning of "higher than or equal to", and "lower than" also includes the meaning of "lower than or equal to".

[0051] Figure 1 This is a schematic flowchart illustrating a scheduling determination method according to an embodiment of the present disclosure. The scheduling determination method shown in this embodiment can be executed by a terminal, which includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with network devices, which include, but are not limited to, network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0052] like Figure 1 As shown, the scheduling determination method may include the following steps:

[0053] In step S101, the relationship set corresponding to the first cell is determined, wherein the relationship set includes the association between the value corresponding to the first information and the scheduling cell identifier;

[0054] In step S102, a first value corresponding to the first information received from the second cell is determined;

[0055] In step S103, the scheduling cell identifier corresponding to the first value is determined according to the association relationship;

[0056] In step S104, based on the relationship between the scheduling cell identifier corresponding to the first value and the identifier of the second cell, it is determined whether the first cell is a cell scheduled by downlink control information (MC-DCI) for scheduling multiple cells received in the second cell.

[0057] In one embodiment, the relationship set may include one or more associations, wherein the association refers to the association between the value corresponding to the first information and the scheduling cell identifier.

[0058] In one embodiment, after receiving the MC-DCI for scheduling multiple cells (specifically, data for scheduling multiple cells) in the second cell, it is necessary to determine which cells the MC-DCI is specifically for scheduling. MC stands for Multi-cell.

[0059] In one embodiment, the first information includes at least one information field in downlink control information (such as the MC-DCI or conventional DCI). The at least one information field may be an existing information field or a newly defined information field. This disclosure does not limit this.

[0060] The technical solutions of this disclosure are illustrated below primarily when the first information includes at least one information field in the MC-DCI that is a Carrier Indicator Field (CIF). It should be understood that the embodiments in this disclosure can also be applied to other information fields in the MC-DCI besides the CIF.

[0061] When determining whether the first cell is a cell scheduled by the MC-DCI, the terminal can make the determination based on the Radio Resource Control (RRC) signaling received in the first cell.

[0062] For example, determining the serving cell configuration of the Information Element (IE) in RRC signaling.

[0063] (ServingCellConfig), then determine the cross-carrier scheduling configuration in the serving cell configuration.

[0064] (CrossCarrierSchedulingConfig) is then used to determine the scheduling cell information (schedulingCellInfo) in the cross-carrier scheduling configuration. Furthermore, if the schedulingCellInfo indicator value is "other", the scheduling cell identifier (schedulingCellId) and the carrier indication field (cif-InScheduingCell) used within the scheduling cell are further determined. For different serving cells, in a multi-carrier scheduling scenario, the values ​​corresponding to the first information used within the configured scheduling cell can be the same.

[0065] If the scheduling cell identifier configured in the RRC signaling is the same as the identifier of the second cell, and the value corresponding to the first information used in the scheduling cell configured in the RRC signaling is the same as the CIF value 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.

[0066] When using MC-DCI to schedule multiple cells, if dynamic handover of scheduled cells is not supported, the above method can configure the same association relationship (the association relationship between the carrier indication field and the scheduling cell identifier) ​​for different scheduled cells. That is, the value corresponding to 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, so as to realize the indication of multiple cells (cell combinations) scheduled by MC-DCI.

[0067] However, when using MC-DCI to schedule multiple cells, the scheduling flexibility of the above method is poor if dynamic handover of scheduled cells is supported. This is because, based on this method, the RRC signaling only carries a combination of a scheduling cell identifier and the value corresponding to the carrier indication field used within the scheduling cell. 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 signaling. When the CIF value in the MC-DCI differs from the value corresponding to the carrier indication field used within the scheduling cell in the RRC signaling, or when the identifier of the scheduling cell (e.g., the second cell where the MC-DCI is received) differs from the scheduling cell identifier in the RRC signaling, the first cell cannot be scheduled. Furthermore, if the scheduling cell handover is achieved by adjusting the CIF value in the MC-DCI, the currently scheduled multiple cells (cell combinations) will no longer be scheduled.

[0068] In the embodiments of this disclosure, the association between the identifier of the scheduled cell and the scheduling cell can be decoupled from the protocol framework in related technologies. The network device can configure a corresponding set of relationships for the serving cell (e.g., the cell currently scheduled by MC-DCI or a cell that MC-DCI can schedule). After the terminal receives RRC signaling in the first cell of the serving cell, and determines that the RRC signaling contains the set of relationships, it can then determine that the set of relationships in the RRC signaling is the set of relationships corresponding to the first cell.

[0069] It should be noted that a terminal can receive RRC signaling in multiple first cells, and each first cell can have its own corresponding set of relationships. The set of relationships corresponding to different first cells can be different or the same, depending on the configuration requirements.

[0070] The relationship set can include the association between the value corresponding to the first information and the scheduling cell identifier, such as the association between the value corresponding to the carrier indication field (i.e., the first information can include the carrier indication field) and the scheduling cell identifier. In RRC signaling, the value corresponding to the carrier indication field can be indicated by the cif-InScheduingCell field. The above relationship set can be carried in RRC signaling, and the types in RRC signaling include, but are not limited to, sequences and choices. For example, it can be a sequence under one indication value "other" in schedulingCellInfo, or a sequence under multiple indication values ​​"other" in schedulingCellInfo.

[0071] The set of relationships between the value corresponding to the first information and the scheduling cell identifier can include the association between a value corresponding to the first information and a scheduling cell identifier. For example, if the value corresponding to the first information is 1, the corresponding scheduling cell identifier is 0.

[0072] The set of relationships between the values ​​corresponding to the first information and the scheduling cell identifier can include the association between multiple values ​​corresponding to the first information and a scheduling cell identifier. For example, when the value corresponding to the first information is 1, the corresponding scheduling cell identifier is 0; when the value corresponding to the first information is 2, the corresponding scheduling cell identifier is 0.

[0073] The set of relationships between the values ​​corresponding to the first information and the scheduling cell identifier can include the association between multiple values ​​corresponding to the first information and multiple scheduling cell identifiers. For example, when the value corresponding to the first information is 1, the corresponding scheduling cell identifier is 0, and when the value corresponding to the first information is 3, the corresponding scheduling cell identifier is 2.

[0074] According to embodiments of this disclosure, the association between the value corresponding to the first information for each first cell and the scheduling cell identifier can be determined. Since the relationship set can define the correspondence between multiple values ​​corresponding to the first information and multiple scheduling cell identifiers, and is not limited to one value corresponding to one scheduling cell identifier, when the network device sends MC-DCI to the terminal based on the relationship set, it is beneficial to improve the scheduling flexibility of the MC-DCI for the first cell. For example, the network device can set the value corresponding to the first information according to the relationship set corresponding to the first cell that needs to be scheduled, thereby dynamically adjusting the multiple cells (cell combinations) scheduled by the MC-DCI.

[0075] Taking the carrier indication field (CIF) in MC-DCI as an example, the first information includes this field.

[0076] For example, in the aforementioned relation set, when the CIF value is 1, the corresponding scheduling cell identifier is 0; when the CIF value is 2, the corresponding scheduling cell identifier is also 0. Therefore, when the network device sends a CIF value of 1 in the MC-DCI sent to the terminal from the second cell with cell identifier 0, it can schedule the first cell; similarly, when the CIF value is 2 in the MC-DCI sent to the terminal from the second cell with cell identifier 0, it can also schedule the first cell. The CIF value can range from 0 to 7, and can be adjusted as needed.

[0077] For example, in the aforementioned relation set, when the CIF value is 1, the corresponding scheduling cell identifier is 0; when the CIF value is 3, the corresponding scheduling cell identifier is 2. Therefore, when the network device sends a MC-DCI with a CIF value of 1 to the terminal from the second cell with cell identifier 0, it can schedule the first cell; similarly, when the network device sends a MC-DCI with a CIF value of 3 to the terminal from the second cell with cell identifier 2, it can also schedule the first cell.

[0078] Figure 2 This is a schematic flowchart illustrating another scheduling determination method according to embodiments of the present disclosure. Figure 2 As shown, determining whether the first cell is a cell scheduled by the MC-DCI based on the relationship between the scheduling cell identifier corresponding to the first value and the identifier of the second cell includes:

[0079] In step S201, if the scheduling cell identifier corresponding to the first value is the same as the identifier of the second cell, the first cell is determined to be a cell scheduled by the MC-DCI; and / or if the scheduling cell identifier corresponding to the first value is different from the identifier of the second cell, the first cell is determined not to be a cell scheduled by the MC-DCI.

[0080] In one embodiment, after receiving MC-DCI in the second cell, the terminal can determine the value corresponding to the first information in MC-DCI, for example, referred to as the first value, and then determine whether the first value exists based on the set of relationships.

[0081] If the first value does not exist in the relation set, then the first cell is determined not to be a cell scheduled by the MC-DCI (the scheduling cell identifier in the relation set does not need to be considered); if the first value exists in the relation set, but the scheduling cell identifier corresponding to the first value is different from the identifier of the second cell, then the first cell is determined not to be a cell scheduled by the MC-DCI; only if the first value exists in the relation set and the scheduling cell identifier corresponding to the first value is the same as the identifier of the second cell, then the first cell is determined to be a cell scheduled by the MC-DCI.

[0082] In one embodiment, determining the set of relationships corresponding to the first cell includes:

[0083] Receive instruction signaling in the first cell;

[0084] The set of relationships is determined in the instruction signaling.

[0085] The network device can send an indication signaling message to the terminal in the first cell, and carry the set of relationships corresponding to the first cell in the indication signaling message. After receiving the indication signaling message in the first cell, when the terminal determines that the indication signaling message carries the set of relationships (for example, the indication signaling message contains one or more associations, and the associations can be the association between the value corresponding to the first information and the scheduling cell identifier), it can determine the set of relationships in the indication signaling message as the set of relationships corresponding to the first cell.

[0086] In one embodiment, the indication signaling includes at least one of the following:

[0087] Radio Resource Control (RRC) layer signaling;

[0088] Media Access Control (MAC) signaling, such as Media Access Control Element (MAC CE);

[0089] Physical layer signaling, such as downlink control information (which can be traditional DCI or MC-DCI).

[0090] In one embodiment, the first information includes at least one information field in MC-DCI, wherein the information field includes a carrier indication field. The method further includes: determining an indication value for scheduling cell information in the radio resource control layer signaling; wherein, if the indication value for the scheduling cell information is other, the relationship set is determined in the radio resource control layer signaling.

[0091] It should be understood that the embodiments of this disclosure are not limited to the case where the indication value of the scheduling cell information is "other". In cases other than "other", the relationship set can be determined in the radio resource control layer signaling as needed. For ease of illustration, the following description focuses on the case where the relationship set is determined in the radio resource control layer signaling when the indication value of the scheduling cell information is "other".

[0092] The cross-carrier scheduling configuration of the RRC signaling received by the terminal in the first cell may include scheduling cell information (schedulingCellInfo). This scheduling cell information may contain multiple data types, such as choice, sequence, boolean, integer, and floating-point. The indicator value for the "choice" type data can be either "own" or "other." In all embodiments of this disclosure, the indicator value of the scheduling cell information may refer to the indicator value of the "choice" type data within the scheduling cell information.

[0093] When the indication value for the scheduling cell information is "own," it means that the first cell can be scheduled by the MC-DCI received by the terminal in the first cell, but not by the MC-DCI received by the terminal in other cells (e.g., the second cell). Therefore, in this case, the terminal has already determined that the first cell is only scheduled by the MC-DCI received by the terminal in the first cell, so the network device does not need to carry the aforementioned relationship set in the RRC signaling. Thus, when the indication value for the scheduling cell information is "own," the terminal does not need to determine the relationship set for multi-cell scheduling in the RRC signaling.

[0094] When the indication value of the scheduling cell information is "other," it indicates that the first cell can be scheduled by MC-DCI received by the terminal in another cell (a cell other than the first cell) (cross-carrier scheduling). Therefore, in this case, the terminal still needs to determine in which cell the MC-DCI received by the terminal is scheduling the first cell. Thus, the network device can carry the aforementioned relationship set in the RRC signaling to allow the terminal to determine whether the first cell is scheduled by MC-DCI received by the terminal in a second cell. The terminal only needs to determine the relationship set in the RRC signaling when the indication value of the scheduling cell information is "other." The value corresponding to the first information in the relationship set can be the value of the carrier indication field (which can be called cif-InScheduingCell-r18) used within the scheduling cell in the scheduling cell information of the RRC signaling.

[0095] Figure 3 This is a schematic diagram illustrating an application scenario according to an embodiment of the present disclosure.

[0096] like Figure 3 As shown, taking the first cell including Cell#1 (cell identifier is 1) and Cell#2 (cell identifier is 2), the second cell including Cell#0 (cell identifier is 0), and the first information including the carrier indication field in MC-DCI as an example.

[0097] The network device carries the relationship set table1-1 in the RRC signaling sent from Cell#1 to the terminal, and the relationship set table1-2 in the RRC signaling sent from Cell#2 to the terminal.

[0098] Table 1-1 contains the associations between multiple carrier indication field values ​​and multiple scheduling cell identifiers. Specifically, when the carrier indication field value is 1, the corresponding scheduling cell identifier is 0; when the carrier indication field value is 2, the corresponding scheduling cell identifier is 0; and when the carrier indication field value is 3, the corresponding scheduling cell identifier is 2. It should be noted that within the same table, the values ​​corresponding to the carrier indication fields are all different.

[0099] Table 1-2 contains the association between the values ​​corresponding to multiple carrier indication fields and a scheduling cell identifier. When the value of the carrier indication field is 1, the corresponding scheduling cell identifier is 0; when the value of the carrier indication field is 3, the corresponding scheduling cell identifier is 0.

[0100] It should be noted that, Figure 3 The blank spaces in the table shown can also be used to set values ​​corresponding to the carrier indication field and the scheduling cell identifier, but these are not used in this example and are therefore not shown. Furthermore, the number of rows in the table is not limited to the four rows shown in the figure; the number of rows can be reduced or increased as needed.

[0101] When the terminal receives the MC-DCI in Cell #0, if the terminal determines that the CIF value in the MC-DCI is 01 (i.e., 1), further, the terminal determines that there is a carrier indication field with a value of 1 in table1-1. Therefore, the terminal can determine 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 in Cell #0. Thus, 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 further determines 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 in 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.

[0102] Network devices can adjust the CIF value in the MC-DCI as needed, thereby adjusting the cell scheduled by the MC-DCI. For example, if the terminal determines that the CIF value in the MC-DCI has changed to 10 (10 in binary corresponds to 2 in decimal), and further determines that there is a carrier indication field with a value of 2 in table1-1, 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.

[0103] The MC-DCI received by the terminal in Cell#0 can be used to schedule cells other than Cell#0, or it can schedule Cell#0 itself. The terminal can determine this by selecting its own or another scheduling cell based on the scheduling cell information configured in the cross-carrier scheduling in the RRC signaling received in Cell#0. If it selects its own, then it can be determined that the MC-DCI can be used to schedule Cell#0 or is not scheduled by any cell; if the indication value of the scheduling cell information is another, then it can be determined that Cell#0 is a scheduled cell, and Cell#0 is scheduled by the MC-DCI received by the terminal in a cell other than Cell#0.

[0104] In one embodiment, if the terminal does not determine the relationship set in the RRC signaling received in the first cell, it can determine whether the first cell is scheduled by the second cell in a traditional manner. For example, it can 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, it can further determine whether the value corresponding to the carrier indication field used in the scheduling cell in the scheduling cell information is the same as the value of CIF 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.

[0105] It should be noted that in all embodiments of this disclosure, each element in the table exists independently. These elements are listed in the same table as an example, but this does not mean that all elements in the table must exist simultaneously as shown in the table. The value of each element is independent of the values ​​of any other element in the table. Therefore, those skilled in the art will understand that the value of each element in the table is an independent embodiment.

[0106] In one implementation, the network device can send the relationship set to the terminal via the RRC signaling, or it can send the relationship set to the terminal via other means, such as by carrying it in the media access control unit, or by determining the relationship set through a predefined method.

[0107] When the set of relationships is carried in RRC signaling and sent to the terminal, it can specifically be carried in the scheduling cell information (schedulingCellInfo-r18) of the RRC signaling. For example, in one embodiment, the scheduling cell information may contain the following:

[0108]

[0109] When the scheduling cell information indication value is "other", the sequence can include n indication combinations, where n is an integer greater than 1. Each indication combination in the sequence contains a set of values ​​corresponding to first information (e.g., carrier indication field) and scheduling cell identifier. The n indication combinations (i.e., the values ​​corresponding to the n first information and the n scheduling cell identifiers) constitute the set carried by the sequence.

[0110] For terminals that do not support multi-cell scheduling, and for terminals that support multi-cell scheduling but receive a legacy MC-DCI (e.g., an MC-DCI used for scheduling a single cell), after receiving the aforementioned set of information, these two types of terminals can determine the cell scheduled by the received legacy MC-DCI based on the existing scheduling cell information (schedulingCellInfo), or they can determine the cell scheduled by the received legacy MC-DCI based on the set of information in the scheduling cell information (which can be called schedulingCellInfo-r18) in this embodiment.

[0111] When determining the cell scheduled by the received legacy MC-DCI according to the set of cell information in this embodiment, the individual cell scheduled by the received legacy MC-DCI can be determined by the value corresponding to the first information in the preset indication combination and the scheduling cell identifier. For example, the individual cell scheduled by the legacy MC-DCI can be determined by the value corresponding to the first information in the first indication combination and the scheduling cell identifier (cif-inSchedulingCell#1 and schedulingCellId#1).

[0112] In one embodiment, the scheduling cell information may include the following:

[0113]

[0114]

[0115] The scheduling cell information may include n other information items. Each other information item may include a sequence of indicators. The sequence of indicators in each other information item may include a set of values ​​corresponding to the first information and the scheduling cell identifier. The sequence of indicators in the n other information items (that is, the values ​​corresponding to the n first information and the n scheduling cell identifiers) constitutes the set carried by the system.

[0116] For terminals that do not support multi-cell scheduling, and for terminals that support multi-cell scheduling but receive a legacy MC-DCI (e.g., an MC-DCI used for scheduling a single cell), after receiving the aforementioned set of information, these two types of terminals can determine the cell scheduled by the received legacy MC-DCI based on the existing scheduling cell information (schedulingCellInfo), or they can determine the cell scheduled by the received legacy MC-DCI based on the set of information in the scheduling cell information (which can be called schedulingCellInfo-r18) in this embodiment.

[0117] When determining the cell scheduled by the received legacy MC-DCI according to the set of cell information in this embodiment, the individual cell scheduled by the received legacy MC-DCI can be determined by the indication combination in the preset other indication value (including the value corresponding to the first information and the scheduling cell identifier). For example, the individual cell scheduled by the received legacy MC-DCI can be determined by the value corresponding to the first information in the indication combination of the first other (other#1) and the scheduling cell identifier.

[0118] Figure 4 This is a schematic flowchart illustrating yet another scheduling determination method according to embodiments of the present disclosure. Figure 4 As shown, taking the first information as including at least one information field in downlink control information, for example including the first information field, the method further includes:

[0119] In step S401, the size (i.e., the number of domains) of the first information domain in the MC-DCI is determined according to the value corresponding to the first information domain in the relation set corresponding to the serving cell; wherein, the serving cell is the serving cell currently scheduled by the MC-DCI (e.g., the first cell) or the serving cell among the cells that the MC-DCI can schedule (including the first cell and cells other than the first cell), and the cells that the MC-DCI can schedule can be defined in the form of a set.

[0120] In one embodiment, the terminal may use different methods to parse the MC-DCI when the size of the first information field in the MC-DCI is different. Therefore, the terminal needs to determine the size of the first information field in the MC-DCI received in the second cell in order to accurately parse the MC-DCI.

[0121] Since the first information field can have multiple values ​​in the set indicated by the network device to the terminal, 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 all the values ​​corresponding to the first information field. Therefore, the size of the first information field in the MC-DCI can be determined based on the range of values ​​corresponding to the first information field in the relation set corresponding to the serving cell. For example, the maximum value of the first information field in the relation set corresponding to the serving cell can be determined, and the size of the first information field in the MC-DCI can be determined based on the maximum value. For example, if the maximum value is 7, the size of the first information field in the MC-DCI can be determined to be 3 bits; if the maximum value is 3, the size of the CIF in the MC-DCI can be determined to be 2 bits.

[0122] In one embodiment, determining the size of the first information field in the MC-DCI based on the value corresponding to the first information field in the set received in the serving cell includes:

[0123] When the range of values ​​corresponding to the first information field in the relation set corresponding to the serving cell is the same, the size of the first information field in the MC-DCI is determined according to the range of values ​​corresponding to the first information field of the serving cell.

[0124] And / or if the range of values ​​corresponding to the first information field in the relation set corresponding to the serving cell is different, the size of the first information field in the MC-DCI is determined according to the maximum range of values ​​corresponding to the first information field in the relation set corresponding to the serving cell.

[0125] If the range of values ​​corresponding to the first information field in the relation set corresponding to the serving cell is the same, then the maximum value of the first information field in the relation set corresponding to the serving cell is the same. Therefore, the size of the CIF in the MC-DCI can be determined based on the range of values ​​corresponding to the first information field (e.g., the maximum value of the carrier indication field). For example, if the range is 0-3, the size of the first information field in the MC-DCI can be determined to be 2 bits; if the range is 0-7, the size of the first information field in the MC-DCI can be determined to be 3 bits.

[0126] When the range of values ​​corresponding to the first information field in the relation set corresponding to the serving cell is different (e.g., partially different or completely different), the maximum value of the first information field in the relation set corresponding to the serving cell can be different. Therefore, it is necessary to determine the maximum range of values ​​corresponding to the first information field in the relation set corresponding to the serving cell, and then determine the size of the first information field in the MC-DCI based on the maximum range. For example, the range of values ​​corresponding to the first information field in the relation set corresponding to cell 1 is 0-3, and the range of values ​​corresponding to the first information field in the set carrier corresponding to cell 2 is 0-7, with a maximum range of 0-7. Based on this, the size of the first information field in the MC-DCI can be determined to be 3 bits.

[0127] Figure 4A This is a schematic flowchart illustrating a scheduling determination method according to an embodiment of the present disclosure. The scheduling determination method can be executed by a terminal, which includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with network devices, which include, but are not limited to, network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0128] like Figure 4A As shown, the scheduling determination method includes:

[0129] In step S401A, a set of relationships corresponding to the first cell is determined, wherein the set of relationships includes the association between the value corresponding to the first information sent by the network device and the first cell;

[0130] In step S401B, the first information is received in the second cell, and the first value corresponding to the first information is determined;

[0131] In step S401C, based on the relationship between the first value and the value of the first information associated with the first cell in the association relationship, it is determined whether the first cell is the cell scheduled by the downlink control information MC-DCI for scheduling multiple cells received in the second cell.

[0132] In one embodiment, the relationship set may include one or more associations, wherein the association refers to the association between the value corresponding to the first information and the first cell.

[0133] According to embodiments of this disclosure, the association between the identifier of the scheduled cell and the scheduled cell can be decoupled from the protocol framework in related technologies. Network devices can configure corresponding relationship sets for serving cells (e.g., cells currently scheduled by MC-DCI or cells that MC-DCI can schedule). After a terminal receives RRC signaling in the first cell of the serving cell, and determines that the RRC signaling contains the relationship set, it can be determined that the relationship set in the RRC signaling is the relationship set corresponding to the first cell.

[0134] It should be noted that a terminal can receive RRC signaling in multiple first cells, and each first cell can have its own corresponding set of relationships. The set of relationships corresponding to different first cells can be different or the same, depending on the configuration requirements.

[0135] The set of relationships may include the association between the value corresponding to the first information and the first cell, such as the association between the value corresponding to the carrier indication field and the first cell.

[0136] The set of relationships between the value corresponding to the first information and the scheduling cell identifier can include an association between the value corresponding to the first information and the first cell, for example, the value of the first information corresponding to the first cell is 1.

[0137] The set of relationships between the values ​​corresponding to the first information and the scheduling cell identifier can include multiple associations between the values ​​corresponding to the first information and the first cell. For example, the values ​​corresponding to the first information of the first cell are 1 and 2.

[0138] According to embodiments of this disclosure, the association between the value corresponding to the first information for each first cell and the first cell can be determined. Since the relationship set can define multiple values ​​corresponding to the first information as associated with the same cell, and is not limited to a single value corresponding to the first information as associated with the first cell, when the network device sends MC-DCI to the terminal based on the relationship set, it is beneficial to improve the scheduling flexibility of MC-DCI for the first cell. For example, the network device can set the first information corresponding to the first cell that needs to be scheduled based on the relationship set, thereby dynamically adjusting the multiple cells (cell combinations) scheduled by MC-DCI.

[0139] Taking the Carrier Indication Field (CIF) in the MC-DCI as an example, the first cell includes Cell#0, Cell#1, and Cell#2.

[0140] For example, in the relation set corresponding to Cell#0, the CIF value corresponding to Cell#0 is 0 and 1; in the relation set corresponding to Cell#1, the CIF value corresponding to Cell#1 is 1 and 2; and in the relation set corresponding to Cell#2, the CIF value corresponding to Cell#2 is 1 and 3.

[0141] When the CIF value in the MC-DCI sent by the terminal in Cell#0 (that is, Cell#0 as the second cell) is 1, since the CIF value is 1, there is a CIF value of 1 in the above relationship between Cell#0, Cell#1 and Cell#2. That is, the CIF value of 1 corresponds to Cell#0, Cell#1 and Cell#2, so it can be determined that the MC-DCI schedules Cell#0, Cell#1 and Cell#2.

[0142] Similarly, when the CIF value in the MC-DCI sent by the terminal in Cell#0 (that is, Cell#0 as the second cell) is 2, since the CIF value is 1, there is a CIF value of 2 in the above relationship corresponding to Cell#1. That is, the CIF value of 2 corresponds to Cell#1, and it can be determined that the MC-DCI schedules Cell#1.

[0143] The following embodiments correspond to some of the embodiments described above, and the implementation methods are similar. You can refer to the corresponding embodiments described above to determine the implementation method, and will not repeat them here.

[0144] In one embodiment, determining whether the first cell is the cell scheduled by the downlink control information (MC-DCI) for scheduling multiple cells received in the second cell, based on the relationship between the first value and the value of the first information associated with the first cell in the association relationship, includes:

[0145] When the first value is the same as the value of the first information associated with the first cell in the association relationship, the first cell is determined to be the cell scheduled by the MC-DCI; and / or

[0146] When the first value is different from the value of the first information associated with the first cell in the association relationship, it is determined that the first cell is not a cell scheduled by the MC-DCI.

[0147] In one embodiment, determining the set of relationships corresponding to the first cell includes:

[0148] Receive instruction signaling in the first cell;

[0149] The set of relationships is determined in the instruction signaling.

[0150] In one embodiment, the indication signaling includes at least one of the following:

[0151] Radio Resource Control (RRC) signaling;

[0152] Media access control layer signaling;

[0153] Physical layer signaling.

[0154] In one embodiment, the first information includes at least one information field in the downlink control information.

[0155] In one embodiment, the information field includes a carrier indication field.

[0156] In one embodiment, the indication signaling includes Radio Resource Control (RRC) signaling, and the method further includes:

[0157] Determine the indication value of the scheduling cell information in the radio resource control layer signaling;

[0158] Wherein, if the indication value of the scheduling cell information is other, the relationship set is determined in the radio resource control layer signaling.

[0159] In one embodiment, the method further includes:

[0160] The size of the first information field in the MC-DCI is determined based on the value corresponding to the first information field in the relation set corresponding to the serving cell; wherein, the serving cell includes the cell currently scheduled by the MC-DCI or the cell that the MC-DCI can schedule.

[0161] In one embodiment, determining the size of the first information field in the MC-DCI based on the value of the first information field in the relation set received in the serving cell includes:

[0162] When the range of values ​​for the first information field in the relation set corresponding to the serving cell is the same, the size of the first information field in the MC-DCI is determined according to the range of values ​​for the first information field.

[0163] and / or

[0164] When the range of values ​​of the first information field in the relation set corresponding to the serving cell is different, the size of the first information field in the MC-DCI is determined according to the maximum range of values ​​of the first information field in the relation set corresponding to the serving cell.

[0165] Figure 5This is a schematic flowchart illustrating an instruction determination method according to an embodiment of the present disclosure. The instruction determination method shown in this embodiment can be executed by a terminal, which includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with network devices, which include, but are not limited to, network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0166] like Figure 5 As shown, the indication determination method may include the following steps:

[0167] In step S501, a set of relationships corresponding to the first cell is determined, wherein the set of relationships includes the association between the value of the first information field and the information indicated by the first information field for the first cell;

[0168] In step S502, the second cell receives downlink control information MC-DCI for scheduling multiple cells and determines the value of the first information field in the MC-DCI.

[0169] In step S503, when the MC-DCI schedules the first cell, the information indicated by the first information field in the MC-DCI for the first cell is determined according to the association relationship.

[0170] 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, Downlink assignment index, PUCCH resource indicator, PDSCH-to-HARQ feedback timing indicator, Antenna port(s), Transmission configuration indication, SRS request, and DMRS sequence initialization.

[0171] The following mainly uses the BWP indicator information field as an example to illustrate the technical solution of this disclosure.

[0172] In one embodiment, when scheduling multiple cells via MC-DCI, the information fields in the MC-DCI also need to provide indications for each of the multiple cells. For example, if the terminal receives the MC-DCI in the second cell (Cell #0), 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 fields in the MC-DCI that indicate the information 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.

[0173] In the embodiments of this disclosure, the network device can configure a corresponding relationship set for the serving cell (e.g., the cell currently scheduled by MC-DCI or the cell that MC-DCI can schedule). For example, after the terminal receives RRC signaling in the first cell of the serving cell, it determines that the RRC signaling contains the relationship set. Then, it can be determined that the relationship set in the RRC signaling is the relationship set corresponding to the first cell.

[0174] It should be noted that a terminal can receive RRC signaling in multiple first cells, and each first cell can have its own corresponding set of relationships. The set of relationships corresponding to different first cells can be different or the same, depending on the configuration requirements.

[0175] The set of relationships between the first information field and the information indicated by the first information field for the first cell may include the association between the value of the first information field and the information indicated by the first information field for the first cell, and may be carried in RRC signaling.

[0176] The set of relationships between the first information field and the information indicated by the first information field for the first cell may include the association between the value of a first information field and the information indicated by the first information field for the first cell. For example, if the value of the first information field is 1, the indication information is BWP identifier 3.

[0177] The set of relationships between the first information field and the information indicated by the first information field for the first cell may include the association between the values ​​of multiple first information fields and the information indicated by multiple first information fields for the first cell. For example, if the value of the first information field is 0, the indication information is BWP identifier 2; if the value of the first information field is 1, the indication information is BWP identifier 3.

[0178] According to embodiments of this disclosure, the association 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. Then, after the terminal receives the MC-DCI in the second cell, it can determine the information indicated by the information field in the MC-DCI for each first cell based on the association. Since the relationship set is allocated and configured for each first cell, the relationship set corresponding to each first cell can be different, facilitating flexible adjustment of the information indicated by the MC-DCI for each first cell.

[0179] In one embodiment, determining the set of relationships corresponding to the first cell includes:

[0180] Receive Radio Resource Control (RRC) signaling in the first cell;

[0181] The set of relationships is determined in the RRC signaling.

[0182] Network devices can send RRC signaling to terminals in the first cell, carrying the relationship set corresponding to the first cell in the RRC signaling. After receiving the RRC signaling in the first cell, if the terminal determines that the RRC signaling carries the relationship set, it can identify the relationship set in the RRC signaling as the relationship set corresponding to the first cell.

[0183] Figure 6A This is a schematic diagram illustrating an application scenario according to an embodiment of the present disclosure. Figure 6B This is a schematic diagram illustrating another application scenario according to an embodiment of the present disclosure.

[0184] like Figure 6A As shown, taking the first cell including Cell#1 (cell identifier is 1) and Cell#2 (cell identifier is 2), the second cell including Cell#0 (cell identifier is 0), and the first information field including BWP indicator as an example.

[0185] 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 relationship set carried by the network device in the RRC signaling sent to the terminal in Cell#0 is table2-0, the relationship set carried in the RRC signaling sent to the terminal in Cell#1 is table2-1, and the relationship set carried in the RRC signaling sent to the terminal in Cell#2 is table2-2.

[0186] Tables 2-0, 2-1, and 2-2 contain the values ​​of multiple first information fields and the correlation between these values ​​and the information indicated by the 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, indicating BWP ID 2; the value of the BWP indicator in the MC-DCI is 01, indicating BWP ID 3; the value of the BWP indicator in the MC-DCI is 10, indicating BWP ID 2; and the value of the BWPindicator in the MC-DCI is 11, indicating BWP ID 10.

[0187] When the terminal receives the MC-DCI in Cell #0, if the terminal determines that the value of the BWP indicator in the MC-DCI is 01 (i.e., 1), further, the terminal determines that there is a BWP indicator with a value of 1 in table 2-0, and can then determine that the information indicated by the BWP indicator with a value of 1 in table 2-0 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 table 2-1, and can then determine that the information indicated by the BWP indicator with a value of 1 in table 2-1 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 table 2-2, and can then determine that the information indicated by the BWP indicator with a value of 1 in table 2-2 is BWP ID 1, thereby determining that the BWP ID indicated by the MC-DCI for Cell #2 is 1.

[0188] like Figure 6B As shown, taking the first cell including Cell#1 (cell identifier is 1) and Cell#2 (cell identifier is 2), the second cell including Cell#0 (cell identifier is 0), and the first information field including ZP CSI-RS trigger as an example.

[0189] The terminal determines that the MC-DCI received in Cell#0 scheduled the first cell Cell#1 and Cell#2, and also scheduled the second cell Cell#0. The network device carries the relationship set table3-0 in the RRC signaling sent from Cell#0 to the terminal, the relationship set table3-1 in the RRC signaling sent from Cell#1 to the terminal, and does not carry the aforementioned relationship set in the RRC signaling sent from Cell#2 to the terminal, or carries the relationship set table3-2, but table3-2 is blank, indicating that no corresponding BWP is configured.

[0190] Tables 3-0 and 3-1 contain the values ​​of multiple first information fields and the relationships between these values ​​and the information indicated by the first information fields for the first cell. For example, in table 3-1, the value of the ZP CSI-RS trigger in MC-DCI is 00, indicating that it is reserved; the value of the ZP CSI-RS trigger in MC-DCI is 01, indicating that the ZP CSI-RS resource set ID is 1.

[0191] When the terminal receives the 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), further, the terminal determines that there is a ZP CSI-RS trigger with a value of 1 in table 3-0, and can then determine that the information indicated by the ZP CSI-RS trigger with a value of 1 in table 3-0 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 table 3-1, and can then determine that the information indicated by the ZP CSI-RS trigger with a value of 1 in table 3-1 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.

[0192] 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 to 11 to 00, or it can be set to 10, 01, 00, 11 from top to bottom, instead of monotonically increasing or decreasing from top to bottom.

[0193] In one implementation, the network device can send the relationship set to the terminal via the RRC signaling, or it can send the relationship set to the terminal via other means, such as by sending it to the terminal via MAC CE.

[0194] When the relationship set is carried in RRC signaling and sent to the terminal, taking BWP indicator as the first information as an example, the RRC signaling may include n indicator combinations, where n is an integer greater than 1. Each indicator combination contains a set of BWP indicator values ​​and BWP IDs. The n indicator combinations (that is, the values ​​of n BWP indicators and BWP IDs) constitute the relationship set.

[0195] For terminals that do not support multi-cell scheduling, and for terminals that support multi-cell scheduling but receive a legacy MC-DCI (e.g., an MC-DCI used for scheduling a single cell), after receiving the above set of relationships, these two types of terminals can determine the BWP ID indicated by the BWP indicator in the received MC-DCI for the first cell based on the value of the BWP indicator and the BWP ID in the preset indication group. For example, the BWPID indicated by the BWP indicator in the received MC-DCI for the first cell can be determined based on the value of the BWPindicator in the first indication group and the BWP ID.

[0196] It should be noted that if the terminal does not receive the aforementioned relationship set in the RRC signaling received in all cells scheduled by MC-DCI, then the information indicated by the first information field for the first cell can be determined according to the legacy method.

[0197] The information indicated by the first information field for the first cell can also be determined in other ways, such as based on the configuration of the reference cell, or based on the configuration parameters related to the first information field in the RRC signaling received in the first cell and the value of the first information field in the MC-DCI.

[0198] The reference cell can be determined according to predefined rules, such as 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.

[0199] Taking the second cell as a reference cell as an example, the first information domain is the BWP indicator, and the configuration parameter related to the first information domain is the number of BWPs.

[0200] If the terminal does not identify the aforementioned relationship set in any of the RRC signaling received in all cells scheduled by MC-DCI, it can first determine the information indicated by the first information field for the reference cell. For example, if the value of the first information field BWP indicator is 11, the information indicated for the second cell (e.g., cell 0) is BWP ID 4.

[0201] Then, the configuration parameters related to the first information field in the RRC signaling 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 signaling received in the first cell and the value of the first information field in the MC-DCI.

[0202] If the configuration parameters related to the first information field in the RRC signaling received in the first cell are greater than or equal to the range of values ​​indicated by the first information field for the reference cell, then it can be determined that the information indicated by the first information field for the first cell in the MC-DCI is the same as the information indicated for the reference cell. For example, if cell 1 is the first cell scheduled by the MC-DCI, and the number of BWPs configured in the RRC signaling 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.

[0203] If the configuration parameter related to the first information field in the RRC signaling received in the first cell is less than the value 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 anything for the first cell, or it can be determined that the value 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 signaling received in the first cell. For example, if cell 2 is the first cell scheduled by the MC-DCI, and the number of BWPs configured in the RRC signaling 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 anything for cell 2, or it can be determined that the BWPindicator in the MC-DCI indicates a BWP ID of 2 for cell 2.

[0204] Figure 7 This is a schematic flowchart illustrating another scheduling determination method according to embodiments of the present disclosure. As shown in FIG6, the method further includes:

[0205] In step S701, the size (i.e., the number of fields) of the first information field in the MC-DCI is determined according to the value of the first information field in the relation set corresponding to the serving cell; wherein, the serving cell is the serving cell currently scheduled by the MC-DCI (e.g., the first cell) or the serving cell among the cells that the MC-DCI can schedule (including cells other than the first cell), and the cells that the MC-DCI can schedule can be defined in the form of a set.

[0206] In one embodiment, the terminal may use different parsing methods for the first information field in the MC-DCI depending on its size. Therefore, the terminal needs to determine the size of the first information field in the MC-DCI received in the second cell in order to perform accurate parsing.

[0207] Since the first information field can have multiple values ​​in the relation set indicated by the network device to the terminal, 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 first information fields in the relation set. Therefore, the size of the CIF in the MC-DCI can be determined based on the range of values ​​of the first information fields in the relation set corresponding to the serving cell. For example, the maximum value of the first information field in the relation set 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; if the maximum value is 3, the size of the CIF in the MC-DCI can be determined to be 2 bits.

[0208] In one embodiment, determining the size of the first information field in the MC-DCI based on the value of the first information field in the relation set received in the serving cell includes:

[0209] When the range of values ​​of the first information field in the relation set corresponding to the serving cell is the same, the size of the first information field in the MC-DCI is determined according to the range of values ​​of the first information field of the serving cell.

[0210] And / or, if the range of values ​​of the first information field in the relation set corresponding to the serving cell is different, the size of the first information field in the MC-DCI is determined according to the maximum range of values ​​of the first information field in the relation set corresponding to the serving cell.

[0211] If the range of values ​​for the first information field in the relation set corresponding to the serving cell is the same, then the maximum value of the first information field in the relation set corresponding to the serving cell is the same. Therefore, the size of the CIF in the MC-DCI can be determined based on the range of values ​​for 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.

[0212] When the range of values ​​for the first information field in the relation set corresponding to the serving cell is different, the maximum value of the first information field in the relation set corresponding to the serving cell can also be different. Therefore, it is necessary to determine the maximum range of values ​​for the first information field in the relation set corresponding to the serving cell, and then determine the size of the first information field in the MC-DCI based on the maximum range. For example, the range in the relation set corresponding to cell 1 is 0-1, and the range in the relation set corresponding to cell 2 is 0-3, with a maximum range of 0-3. Based on this, the size of the CIF in the MC-DCI can be determined to be 2 bits.

[0213] Figure 8 This is a schematic flowchart illustrating an association relationship indication method according to an embodiment of the present disclosure. The association relationship indication method shown in this embodiment can be executed by a network device that can communicate with a terminal. The network device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.

[0214] like Figure 8 As shown, the association relationship indication method may include the following steps:

[0215] In step S801, the terminal is instructed to the relationship set corresponding to the first cell, wherein the relationship set includes the association between the value corresponding to the first information and the scheduling cell identifier.

[0216] In the embodiments of this disclosure, the network device can configure a corresponding relationship set for the serving cell (e.g., the cell currently scheduled by MC-DCI or the cell that MC-DCI can schedule). After the terminal receives RRC signaling in the first cell of the serving cell, it determines that the RRC signaling contains the relationship set. Then, it can be determined that the relationship set in the RRC signaling is the relationship set corresponding to the first cell.

[0217] It should be noted that network devices can send RRC signaling to terminals from multiple first cells, and each first cell can have its own corresponding set of relationships. The set of relationships corresponding to different first cells can be different or the same, depending on the configuration requirements.

[0218] The relationship set can include the association between multiple values ​​corresponding to the first information and the scheduling cell identifier. In RRC signaling, the value corresponding to the first information can be indicated by the cif-InScheduingCell field. The above association can be carried in RRC signaling. The types in RRC signaling include, but are not limited to, sequence, choice, etc. For example, it can be a sequence under a single indication value "other" in schedulingCellInfo, or it can be a sequence under multiple indication values ​​"other" in schedulingCellInfo.

[0219] The set of relationships between the carrier indication field and the scheduling cell identifier mentioned above may include the association between a value corresponding to a first piece of information and a scheduling cell identifier. For example, if the value corresponding to the first piece of information is 1, the corresponding scheduling cell identifier is 0.

[0220] The set of relationships between the carrier indication field and the scheduling cell identifier mentioned above may include the association between multiple values ​​corresponding to the first information and a scheduling cell identifier. For example, if the value corresponding to the first information is 1, the corresponding scheduling cell identifier is 0; if the value corresponding to the first information is 2, the corresponding scheduling cell identifier is 0.

[0221] The set of relationships between the carrier indication field and the scheduling cell identifier can include the association between multiple values ​​corresponding to the first information and multiple scheduling cell identifiers. For example, if the value corresponding to the first information is 1, the corresponding scheduling cell identifier is 0; if the value corresponding to the first information is 3, the corresponding scheduling cell identifier is 2.

[0222] According to embodiments of this disclosure, a network device can determine the association between the value corresponding to the first information of each first cell and the scheduling cell identifier, and carry the association in a relationship set to indicate it to the terminal. Since the relationship set can define the correspondence between multiple values ​​corresponding to the first information and multiple scheduling cell identifiers, and is not limited to one value corresponding to one scheduling cell identifier, the subsequent sending of the MC-DCI to the terminal based on the relationship set by the network device is beneficial to improving the scheduling flexibility of the MC-DCI for the first cell. For example, the network device can set the CIF value in the sent MC-DCI according to the relationship set corresponding to the first cell that needs to be scheduled, thereby dynamically adjusting the multiple cells (cell combinations) to be scheduled.

[0223] For example, in the aforementioned relationship set, if the value corresponding to the first information is 1, the corresponding scheduling cell identifier is 0; if the value corresponding to the first information is 2, the corresponding scheduling cell identifier is 0. Therefore, when the network device sends a CIF value of 1 in the MC-DCI sent to the terminal from the second cell with cell identifier 0, it can schedule the first cell; similarly, when the CIF value in the MC-DCI sent to the terminal from the second cell with cell identifier 0 is 2, it can also schedule the first cell.

[0224] For example, in the aforementioned relationship set, the value corresponding to the first information is 1, and the corresponding scheduling cell identifier is 0; the value corresponding to the first information is 3, and the corresponding scheduling cell identifier is 2. Therefore, when the network device sends a CIF value of 1 in the MC-DCI sent to the terminal from the second cell with cell identifier 0, it can schedule the first cell; similarly, when the CIF value in the MC-DCI sent to the terminal from the second cell with cell identifier 2 is 3, it can also schedule the first cell.

[0225] Figure 9 This is a schematic flowchart illustrating another method for indicating association relationships according to embodiments of the present disclosure. Figure 9 As shown, the method further includes:

[0226] In step S901, it is determined that the first cell is scheduled by sending the MC-DCI for scheduling multiple cells in the second cell, and the first value of the first information corresponding to the identifier of the second cell is determined according to the association relationship.

[0227] In step S902, the MC-DCI is sent to the terminal in the second cell, wherein the value corresponding to the first information in the MC-DCI is equal to the first value.

[0228] In one embodiment, after the network device sends the association relationship to the terminal in the relationship set, when it needs to schedule the first cell by sending MC-DCI in the second cell, it can determine the first value of the carrier indication field corresponding to the identifier of the second cell based on the association relationship. Then, in the MC-DCI sent from the second cell to the terminal, the CIF value in the MC-DCI can be set to equal the first value. After receiving the MC-DCI in the second cell, the terminal can determine that the scheduling cell identifier corresponding to the first value of CIF in the MC-DCI in the relationship set is the same as the identifier of the second cell, thereby determining that the first cell is the cell scheduled by the MC-DCI.

[0229] In one embodiment, sending the relationship set corresponding to the first cell to the terminal includes: sending RRC signaling to the terminal in the first cell, wherein the RRC signaling carries the relationship set.

[0230] Network devices can send RRC signaling to terminals in the first cell, carrying the relationship set corresponding to the first cell in the RRC signaling. After receiving the RRC signaling in the first cell, if the terminal determines that the RRC signaling carries the relationship set, it can identify the relationship set in the RRC signaling as the relationship set corresponding to the first cell.

[0231] In one embodiment, sending the relationship set corresponding to the first cell to the terminal includes: sending an indication signaling message to the terminal in the first cell, wherein the indication signaling message carries the relationship set.

[0232] In one embodiment, the indication signaling includes at least one of the following:

[0233] Radio Resource Control (RRC) signaling;

[0234] Media access control layer signaling;

[0235] Physical layer signaling.

[0236] In one embodiment, the first information includes at least one information field in the downlink control information.

[0237] In one embodiment, the information field includes a carrier indication field.

[0238] In one embodiment, the indication signaling includes Radio Resource Control (RRC) signaling, and the method further includes: determining an indication value for scheduling cell information in the RRC signaling; wherein, if the indication value for the scheduling cell information is other, the relationship set is carried in the RRC signaling.

[0239] The cross-carrier scheduling configuration of the RRC signaling sent by the network device to the terminal in the first cell may include scheduling cell information. This scheduling cell information may contain multiple types of data, such as choice, sequence, boolean, integer, and floating-point data. The indicator value for the "choice" type data can be either "own" or "other." In all embodiments of this disclosure, the indicator value of the scheduling cell information may refer to the indicator value of the "choice" type data within the scheduling cell information.

[0240] When the indication value for scheduling cell information is "own", it means that the first cell can be scheduled by MC-DCI sent from the first cell, but not by MC-DCI sent from other cells (e.g., the second cell). Therefore, in this case, it has been determined that the first cell is only scheduled by MC-DCI received by the terminal in the first cell, so the network device does not need to carry the set of relationships for multi-cell scheduling in the RRC signaling.

[0241] When the indication value of the scheduling cell information is "other," it indicates that the first cell can be scheduled by MC-DCI transmitted from other cells (cross-carrier scheduling). Therefore, in this case, the terminal still needs to determine in which cell the MC-DCI received by the terminal is scheduled for the first cell. Thus, the network device can carry the aforementioned relationship set in the RRC signaling to allow the terminal to determine whether the first cell is scheduled by MC-DCI received by the terminal in a second cell. The value of the carrier indication field in the association relationship can be the value of the carrier indication field used within the scheduling cell in the scheduling cell information of the RRC signaling (which can be called cif-InScheduingCell-r18).

[0242] In one embodiment, the method further includes: determining the size of the first information field in the MC-DCI based on the value corresponding to the first information field in the relation set corresponding to the serving cell; wherein the serving cell includes the cell currently scheduled by the MC-DCI or the cell that the MC-DCI can schedule, and the cell that the MC-DCI can schedule can be defined in the form of a set.

[0243] In one embodiment, the terminal may use different parsing methods for CIF in MC-DCI when the size is different. Therefore, the terminal needs to determine the size of CIF in the MC-DCI received in the second cell in order to perform accurate parsing.

[0244] Since the carrier indication field can have multiple values ​​in the relationship set 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 values ​​of the carrier indication fields in the relationship set corresponding to the serving cell. For example, the maximum value of the carrier indication field in the relationship set 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 7, the size of the CIF in the MC-DCI can be determined to be 3 bits; if the maximum value is 3, the size of the CIF in the MC-DCI can be determined to be 2 bits.

[0245] In one embodiment, determining the size of the first information field in the MC-DCI based on the value corresponding to the first information field in the relation set corresponding to the serving cell includes:

[0246] When the range of values ​​corresponding to the first information field in the relation set corresponding to the serving cell is the same, the size of the first information field in the MC-DCI is determined according to the range of values ​​corresponding to the first information field.

[0247] And / or if the range of values ​​corresponding to the first information field in the relation set corresponding to the serving cell is different, the size of the first information field in the MC-DCI is determined according to the maximum range of values ​​corresponding to the first information field in the relation set corresponding to the serving cell.

[0248] If the range of values ​​for the carrier indication field in the relation set corresponding to the serving cell is the same, then the maximum value of the carrier indication field in the relation set corresponding to the serving cell is the same. Therefore, the size of the CIF in the MC-DCI can be determined based on the range of values ​​for 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; if the range is 0-7, the size of the CIF in the MC-DCI can be determined to be 3 bits.

[0249] When the range of values ​​for the carrier indication field in the relation set corresponding to the serving cell is different, the maximum value of the carrier indication field in the relation set corresponding to the serving cell can also be different. Therefore, it is necessary to determine the maximum range of values ​​for the carrier indication field in the relation set corresponding to the serving cell, and then determine the size of the CIF in the MC-DCI based on the maximum range. For example, the range in the relation set corresponding to cell 1 is 0-3, and the range in the relation set corresponding to cell 2 is 0-7, with a maximum range of 0-7. Based on this, the size of the CIF in the MC-DCI can be determined to be 3 bits.

[0250] Figure 9A This is a schematic flowchart illustrating an association relationship indication method according to an embodiment of the present disclosure. The association relationship indication method shown in this embodiment can be executed by a network device that can communicate with a terminal. The network device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.

[0251] like Figure 9A As shown, the association relationship indication method may include the following steps:

[0252] In step 901A, the terminal is indicated with the relationship set corresponding to the first cell, wherein the relationship set includes the association between the value corresponding to the first information sent by the network device and the first cell.

[0253] The following embodiments correspond to some of the embodiments described above, and the implementation methods are similar. You can refer to the corresponding embodiments described above to determine the implementation method, and will not repeat them here.

[0254] In one embodiment, the method further includes:

[0255] It is determined that the first cell is scheduled by sending MC-DCI for scheduling multiple cells in the second cell, and the first value of the first information corresponding to the first cell is determined according to the association relationship.

[0256] The sending module is further configured to send the first information to the terminal in the second cell, wherein the value corresponding to the first information is equal to the first value.

[0257] In one embodiment, determining the set of relationships corresponding to the first cell includes: receiving indication signaling in the first cell; and determining the set of relationships in the indication signaling.

[0258] In one embodiment, the indication signaling includes at least one of the following: radio resource control layer signaling; media access control layer signaling; physical layer signaling.

[0259] In one embodiment, the first information includes at least one information field in the downlink control information.

[0260] In one embodiment, the information field includes a carrier indication field.

[0261] In one embodiment, the indication signaling includes radio resource control (RFC) signaling, and the method further includes: determining an indication value for scheduling cell information in the RFC signaling; wherein, if the indication value for scheduling cell information is other, the relationship set is determined in the RFC signaling.

[0262] In one embodiment, the method further includes: determining the size of the first information field in the MC-DCI based on the value corresponding to the first information field in the relation set corresponding to the serving cell; wherein the serving cell includes the cell currently scheduled by the MC-DCI or the cell that the MC-DCI can schedule.

[0263] In one embodiment, determining the size of the first information field in the MC-DCI based on the value of the first information field in the relation set received in the serving cell includes: if the range of values ​​of the first information field in the relation set corresponding to the serving cell is the same, determining the size of the first information field in the MC-DCI based on the range of values ​​of the first information field; and / or if the range of values ​​of the first information field in the relation set corresponding to the serving cell is different, determining the size of the first information field in the MC-DCI based on the maximum range of values ​​of the first information field in the relation set corresponding to the serving cell.

[0264] Figure 10This is a schematic flowchart illustrating an association relationship indication method according to an embodiment of the present disclosure. The association relationship indication method shown in this embodiment can be executed by a network device that can communicate with a terminal. The network device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.

[0265] like Figure 10 As shown, the association relationship indication method may include the following steps:

[0266] In step S1001, the terminal is indicated with the relationship set corresponding to the first cell, wherein the relationship set includes the association between the value of the first information field and the information indicated by the first information field for the first cell.

[0267] In one embodiment, when scheduling multiple cells via MC-DCI, the information fields in the MC-DCI also need to provide indications for each of the multiple cells. For example, if the MC-DCI is sent to the terminal from Cell #0 in the second cell, and the first cells to be scheduled by the MC-DCI include Cell #1 and Cell #2, then it is necessary to determine the information fields in the MC-DCI that indicate the information 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.

[0268] In the embodiments of this disclosure, the network device can configure a corresponding relationship set for the serving cell (e.g., the cell currently scheduled by MC-DCI or the cell that MC-DCI can schedule). For example, after the terminal receives RRC signaling in the first cell of the serving cell, it determines that the RRC signaling contains the relationship set. Then, it can be determined that the relationship set in the RRC signaling is the relationship set corresponding to the first cell.

[0269] It should be noted that a terminal can receive RRC signaling in multiple first cells, and each first cell can have its own corresponding set of relationships. The set of relationships corresponding to different first cells can be different or the same, depending on the configuration requirements.

[0270] The set of relationships between the first information field and the information indicated by the first information field for the first cell may include the association between the value of the first information field and the information indicated by the first information field for the first cell, and may be carried in the RRC signaling in the form of a table.

[0271] The set of relationships between the first information field and the information indicated by the first information field for the first cell may include the association between the value of a first information field and the information indicated by the first information field for the first cell. For example, if the value of the first information field is 1, the indication information is BWP identifier 3.

[0272] The set of relationships between the first information field and the information indicated by the first information field for the first cell may include the association between the values ​​of multiple first information fields and the information indicated by multiple first information fields for the first cell. For example, if the value of the first information field is 0, the indication information is BWP identifier 2; if the value of the first information field is 1, the indication information is BWP identifier 3.

[0273] According to embodiments of this disclosure, a network device can determine the association between the value of a first information field corresponding to each first cell and the information indicated by the first information field for the first cell, and indicate this association to a terminal. This allows the terminal, after receiving the MC-DCI in a second cell, to determine the information indicated by the information field in the MC-DCI for each first cell based on the association. Since the association set is configured for each first cell, the association set corresponding to each first cell can be different, facilitating flexible adjustment of the information indicated by the MC-DCI for each first cell.

[0274] Figure 11 This is a schematic flowchart illustrating another method for indicating association relationships according to embodiments of the present disclosure. Figure 11 As shown, the method further includes:

[0275] In step S1101, the first information indicated to the first cell by the first information field in the MC-DCI for scheduling multiple cells sent by the second cell is determined, and the value of the first information field corresponding to the first information is determined according to the association relationship.

[0276] In step S1102, the MC-DCI is sent to the terminal in the second cell, wherein the value of the first information field in the MC-DCI is equal to the value of the first information field corresponding to the first information in the association relationship.

[0277] In one embodiment, after the network device sends the association relationship to the terminal in a relationship set, when it needs to indicate first information for the first cell through the first information field, it can determine the value of the first information field corresponding to the first information based on the association relationship. Then, in the MC-DCI sent from 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 receiving the MC-DCI in the second cell, the terminal can determine the first information corresponding to the value of the first information field in the MC-DCI in the relationship set, thereby determining that the information indicated by the first information field in the MC-DCI for the first cell is the first information.

[0278] In one embodiment, the method further includes: determining the size of the first information field in the MC-DCI based on the value of the first information field in the relation set corresponding to the serving cell; wherein the serving cell includes the cell currently scheduled by the MC-DCI or the cell that the MC-DCI can schedule, and the cell that the MC-DCI can schedule can be defined in the form of a set.

[0279] In one embodiment, the terminal may use different parsing methods for the first information field in the MC-DCI depending on its size. Therefore, the terminal needs to determine the size of the first information field in the MC-DCI received in the second cell in order to perform accurate parsing.

[0280] Since the first information field can have multiple values ​​in the relation set indicated by the network device to the terminal, 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 first information fields in the relation set. Therefore, the size of the CIF in the MC-DCI can be determined based on the range of values ​​of the first information fields in the relation set corresponding to the serving cell. For example, the maximum value of the first information field in the relation set 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; if the maximum value is 3, the size of the CIF in the MC-DCI can be determined to be 2 bits.

[0281] In one embodiment, determining the size of the first information field in the MC-DCI based on the value of the first information field in the relation set received in the serving cell includes:

[0282] When the range of values ​​of the first information field in the relation set corresponding to the serving cell is the same, the size of the first information field in the MC-DCI is determined according to the range of values ​​of the first information field of the serving cell.

[0283] And / or if the range of values ​​of the first information field in the relation set corresponding to the serving cell is different, the size of the first information field in the MC-DCI is determined according to the maximum range of values ​​of the first information field in the relation set corresponding to the serving cell.

[0284] If the range of values ​​for the first information field in the relation set corresponding to the serving cell is the same, then the maximum value of the first information field in the relation set corresponding to the serving cell is the same. Therefore, the size of the CIF in the MC-DCI can be determined based on the range of values ​​for 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.

[0285] When the range of values ​​for the first information field in the relation set corresponding to the serving cell is different, the maximum value of the first information field in the relation set corresponding to the serving cell can also be different. Therefore, it is necessary to determine the maximum range of values ​​for the first information field in the relation set corresponding to the serving cell, and then determine the size of the first information field in the MC-DCI based on the maximum range. For example, the range in the relation set corresponding to cell 1 is 0-1, and the range in the relation set corresponding to cell 2 is 0-3, with a maximum range of 0-3. Based on this, the size of the CIF in the MC-DCI can be determined to be 2 bits.

[0286] In one embodiment, sending the relationship set corresponding to the first cell to the terminal includes: sending RRC signaling to the terminal in the first cell, wherein the RRC signaling carries the relationship set.

[0287] Network devices can send RRC signaling to terminals in the first cell, carrying the relationship set corresponding to the first cell in the RRC signaling. After receiving the RRC signaling in the first cell, if the terminal determines that the RRC signaling carries the relationship set, it can identify the relationship set in the RRC signaling as the relationship set corresponding to the first cell.

[0288] Corresponding to the aforementioned embodiments of the scheduling determination method, indication determination method, and association relationship indication method, this disclosure also provides embodiments of the scheduling determination device, indication determination device, and association relationship indication device.

[0289] Figure 12This is a schematic block diagram illustrating a scheduling determination device according to an embodiment of the present disclosure. The scheduling determination device 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.
