Fig. 1 is a schematic flow chart diagram illustrating a method of schedule determination in accordance with an embodiment of the present disclosure. The scheduling determination method shown in this embodiment may be executed by a terminal, where the terminal includes but is not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other communication devices. The terminal may communicate with network devices including, but not limited to, network devices in 4G, 5G, 6G, etc. communication systems, such as base stations, core networks, etc.

As shown in fig. 1, the scheduling determination method may include the steps of:

in step S101, determining an association relationship corresponding to a first Cell (Cell), where the association relationship includes an association relationship between a value of a carrier indicator field and a scheduling Cell identifier, and is used to determine whether the first Cell is a Cell scheduled by a second Cell;

in step S102, receiving, in a second cell, a downlink control information DCI for scheduling multiple cells, and determining a first value of a Carrier Indicator Field (CIF) in the DCI;

in step S103, determining a scheduling cell identifier corresponding to the first value according to the association relationship;

in step S104, it is determined whether the first cell is the cell scheduled by the DCI according to a relationship between the identifier of the scheduling cell corresponding to the first value and the identifier of the second cell (for example, the terminal may determine the identifier of the second cell according to the system information).

In one embodiment, after receiving DCI for scheduling multiple cells (specifically, data for scheduling multiple cells) in a second cell, it is necessary to determine which cells the DCI is specifically scheduled for. For convenience of description, DCI for scheduling a plurality of cells is hereinafter referred to as MC-DCI, where MC denotes a Multi-cell (Multi-cell).

When determining whether the first cell is the cell scheduled by the MC-DCI, the terminal may determine according to a Radio Resource Control (RRC) message received in the first cell.

For example, an Information Element (IE) in the RRC message is determined, a serving cell configuration (ServingCellConfig) is then determined, a cross-carrier scheduling configuration (crosscarrierscheduledconfig) in the serving cell configuration is then determined, scheduling cell Information (schedulingCellInfo) is then determined in the cross-carrier scheduling configuration, and when the schedulingCellInfo indicated value is other (other), a scheduling cell identification (schedulingCellId) in the schedulingCellInfo and a carrier indication field (cif-schedulingcell) used in the scheduling cell are further determined. For different serving cells, in a multi-carrier scheduling scenario, the values of the carrier indication fields used in the configured scheduling cell may be the same.

The identity of the scheduling cell configured in the RRC message is the same as the identity of the second cell, and the value of the carrier indicator field used in the scheduling cell configured in the RRC message is the same as the value of the CIF in the MC-DCI received in the second cell, it may be determined that the MC-DCI received in the second cell is used to schedule the first cell.

Under the condition of scheduling a plurality of cells by using MC-DCI, if dynamic switching of the scheduled cells is not supported, the above manner can configure the same association relation for different scheduled cells, that is, the values of carrier indication fields in the association relation of each scheduled cell are the same, and the identification of the scheduled cell in the association relation of each scheduled cell is the same, thereby realizing indication of a plurality of cells (cell combination) scheduled by MC-DCI.

However, in the case of scheduling multiple cells by using MC-DCI, if dynamic handover of the scheduled cell is supported, the scheduling flexibility of the above method is poor because, based on this method, an RRC message only carries a combination of a single scheduling cell identifier and a value of a carrier indication field used in a scheduling cell, and a terminal can only determine whether a first cell is scheduled by MC-DCI transmitted by a cell corresponding to the scheduling cell identifier in the RRC message according to this RRC message, and when the value of CIF in MC-DCI is different from the value of the carrier indication field used in the scheduling cell of the RRC message, or when the identifier of the scheduling cell (for example, a second cell where the MC-DCI is received) is different from the scheduling cell identifier in the RRC message, the first cell cannot be scheduled. And if the scheduling cell switching is realized by adjusting the CIF value in the MC-DCI, a plurality of currently scheduled cells (cell combination) are not scheduled any more.

In the embodiment of the present disclosure, the network device may configure a corresponding association relationship for a serving cell (for example, a cell currently scheduled by MC-DCI or a cell that can be scheduled by MC-DCI), and after determining that an RRC message received by a first cell in the serving cell includes the association relationship, the terminal may determine that the association relationship in the RRC message is the association relationship corresponding to the first cell.

It should be noted that the terminal may receive the RRC message in a plurality of first cells, and each first cell may have a corresponding association relationship. The association relations corresponding to different first cells may be different or the same, and may be specifically configured as required.

The association relationship may include an association relationship between values of the multiple carrier indication fields and the scheduling cell identifier, and in the RRC message, the value of the corresponding carrier indication field may be indicated by the cif-scheduling cell field. The association relationship may be carried in an RRC message, and the type in the RRC message includes, but is not limited to, a sequence (sequence), a selection (choice), and the like, for example, the association relationship may be a sequence under one indication value "other" in the schedulingCellInfo, or may be a sequence under multiple indication values "other" in the schedulingCellInfo.

The association relationship between the carrier indication domain and the scheduling cell identifier may include an association relationship between a value of one carrier indication domain and one scheduling cell identifier, for example, the value of the carrier indication domain is 1, and the corresponding scheduling cell identifier is 0;

the association relationship between the carrier indication domain and the scheduling cell identifier may include an association relationship between values of a plurality of carrier indication domains and one scheduling cell identifier, for example, a value of a carrier indication domain is 1, a corresponding scheduling cell identifier is 0, a value of a carrier indication domain is 2, and a corresponding scheduling cell identifier is 0;

the association relationship between the carrier indication field and the scheduling cell identifier may include an association relationship between values of a plurality of carrier indication fields and a plurality of scheduling cell identifiers, for example, a value of a carrier indication field is 1, a corresponding scheduling cell identifier is 0, a value of a carrier indication field is 3, and a corresponding scheduling cell identifier is 2.

According to the embodiment of the disclosure, the association relationship between the value of the carrier indication domain corresponding to each first cell and the scheduling cell identifier may be determined, and since the association relationship may define the correspondence relationship between the values of the plurality of carrier indication domains and the plurality of scheduling cell identifiers, and is not limited to that the value of one carrier indication domain is associated with one scheduling cell identifier, when the network device sends MC-DCI to the terminal according to the association relationship, it is beneficial to improve the scheduling flexibility of the MC-DCI to the first cell. For example, the network device may set a CIF value in the transmitted MC-DCI according to the association relationship corresponding to the first cell to be scheduled, so as to dynamically adjust the scheduled multiple cells (cell combinations).

For example, in the association relationship, the value of the carrier indication field is 1, the corresponding scheduling cell identifier is 0, the value of the carrier indication field is 2, and the corresponding scheduling cell identifier is 0. Then, the network device may implement scheduling for the first cell when the value of CIF in MC-DCI sent to the terminal in the second cell with cell identifier 0 is 1, and may also implement scheduling for the first cell when the value of CIF in MC-DCI sent to the terminal in the second cell with cell identifier 0 is 2. The range of the CIF value may be 0 to 7, and may be adjusted as needed.

For example, in the association relationship, the value of the carrier indication field is 1, the corresponding scheduling cell identifier is 0, the value of the carrier indication field is 3, and the corresponding scheduling cell identifier is 2. Then, the network device may implement scheduling for the first cell when the value of CIF in MC-DCI sent to the terminal in the second cell with cell identifier 0 is 1, and may also implement scheduling for the first cell when the value of CIF in MC-DCI sent to the terminal in the second cell with cell identifier 2 is 3.

Fig. 2 is a schematic flow chart diagram illustrating another method of schedule determination in accordance with an embodiment of the present disclosure. As shown in fig. 2, the determining whether the first cell is the cell scheduled by the DCI according to the relationship between the identifier of the scheduling cell corresponding to the first value and the identifier of the second cell includes:

in step S201, determining that the first cell is the cell scheduled by the DCI when the identifier of the scheduling cell corresponding to the first value is the same as the identifier of the second cell; and/or determining that the first cell is not the cell scheduled by the DCI under the condition that the identification of the scheduling cell corresponding to the first value is different from the identification of the second cell.

In an embodiment, after receiving the MC-DCI in the second cell, the terminal may determine a value of a CIF in the MC-DCI, for example, referred to as a first value, and further may determine whether the first value exists according to the association relationship.

If the first value does not exist in the association relationship, determining that the first cell is not the cell scheduled by the MC-DCI (without considering the identification of the scheduling cell in the association relationship); if the incidence relation has a first value, but the identification of the scheduling cell corresponding to the first value is different from the identification of the second cell, determining that the first cell is not the cell scheduled by the MC-DCI; and if the first value exists in the association relationship and the identification of the scheduling cell corresponding to the first value is the same as the identification of the second cell, determining that the first cell is the cell scheduled by the MC-DCI.

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

receiving a radio resource control, RRC, message at the first cell;

determining the association in the RRC message.

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

In one embodiment, the method further comprises: determining an indication value of scheduling cell information in the RRC message; and determining the association relationship in the RRC message when the indicated value of the scheduling cell information is other.

The terminal may include scheduling cell information, scheduling cellinfo, in the cross-carrier scheduling configuration of the RRC message received by the first cell, and the scheduling cell information may include multiple types of data, such as selection (choice), sequence (sequence), boolean (boolean), integer, floating point, etc., where an indication value of the "selection" type of data may be itself (own) or others (other). In all embodiments of the present disclosure, the indication value of the scheduling cell information may refer to an indication value of "selection" type data in the scheduling cell information.

In the case that the indicated value of the scheduling cell information is self (own), it indicates that the first cell may be scheduled by the DCI received by the terminal in the first cell, but not by the DCI received by the terminal in another cell (e.g., a second cell). It can be seen that, in this case, the terminal has already determined that the first cell is only scheduled by the DCI received by the terminal in the first cell, so the network device does not need to carry the association relationship in the RRC message. Then in case that the indicated value of the scheduling cell information is self, the terminal does not need to determine the association relationship of multi-cell scheduling in the RRC message.

In the case that the indicated value of the scheduling cell information is other (other), it indicates that the first cell may be scheduled by DCI received by the terminal in other cells (cells other than the first cell) (cross-carrier scheduling), and it is seen that in this case, the terminal still needs to determine in which cell the DCI received by the terminal is scheduled in the first cell, so the network device may carry the association in an RRC message, so that the terminal determines whether the first cell is scheduled by MC-DCI received by the terminal in the second cell. The terminal is also required to determine the association relationship in the RRC message only when the indicated value of the scheduling cell information is other. The value of the carrier indication field in the association relationship may be a value of a carrier indication field (which may be referred to as cif-scheduling cell-r 18) used in a scheduling cell in the scheduling cell information in the RRC message.

As shown in fig. 3, the first Cell includes Cell #1 (Cell id is 1) and Cell #2 (Cell id is 2), and the second Cell includes Cell #0 (Cell id is 0).

The association relationship carried in the RRC message sent by the Cell #1 to the terminal is table1-1, and the association relationship carried in the RRC message sent by the Cell #2 to the terminal is table1-2.

table1-1 contains the association between the values of multiple carrier indication domains and multiple scheduling cell identifiers, where the value of a carrier indication domain is 1, the corresponding scheduling cell identifier is 0, the value of a carrier indication domain is 2, and the corresponding scheduling cell identifier is 0; the value of the carrier indication field is 3, and the corresponding scheduling cell identifier is 2. It should be noted that, in the same table, the values of the carrier indication fields are different.

table1-2 contains the association between the values of multiple carrier indication fields and one scheduling cell identifier, where the value of a carrier indication field is 1, the corresponding scheduling cell identifier is 0, the value of a carrier indication field is 3, and the corresponding scheduling cell identifier is 0.

Note that, in a blank portion in the table (table) shown in fig. 3, a value of the carrier indication field and a scheduling cell identifier may also be set, but this embodiment is not used in the example process, and therefore is not shown. In addition, the number of rows in the table is not limited to the 4 rows shown in the figure, and the number of rows may be decreased or increased as necessary.

When the terminal receives the MC-DCI in Cell #0, if the terminal determines that the value of the CIF in the MC-DCI is 01 (i.e. 1), further, the terminal determines that a carrier indication field with a value of 1 exists in table1-1, and further may 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 of Cell #0. Thus, cell #1 can be determined as the Cell scheduled by the MC-DCI received by the terminal in Cell #0. The terminal determines that a carrier indication domain with a value of 1 exists in table1-2, and further determines that a corresponding scheduling Cell identifier of the carrier indication domain with the value of 1 in table1-2 is 0, which is the same as the identifier of Cell #0. Thereby, cell #2 can be determined as the Cell scheduled by the MC-DCI received by the terminal in Cell #0.

The network device may adjust a value of a CIF in the MC-DCI as needed, so as to adjust a Cell scheduled by the MC-DCI, for example, the terminal determines that the value of the CIF in the MC-DCI is changed to 10 (i.e. 2), further, the terminal determines that a carrier indication field with a value of 2 exists in table1-1, and further may determine that a 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. Thus, cell #1 can be determined as the Cell scheduled by the MC-DCI received by the terminal in Cell #0. The terminal determines that no carrier indication field with a value of 1 exists in table1-2, and then it may be determined that Cell #2 is not a Cell scheduled by the MC-DCI received by the terminal in Cell #0.

The MC-DCI received by the terminal in Cell #0 may schedule cells other than Cell #0, or may schedule Cell #0, and the terminal may select (choice) as its own (own) or other (other) according to the scheduling Cell information configured in cross-carrier scheduling in the RRC message received in Cell #0. If selected as self, it may be determined that MC-DCI may be used to schedule Cell #0 or not scheduled by any Cell; if the indication value of the scheduling Cell information is other, it can be determined that Cell #0 is the scheduled Cell, and Cell #0 is scheduled by the DCI received by the terminal in the Cell other than Cell #0.

In an embodiment, when the terminal does not determine the association relationship in the RRC message received by the first cell, it may determine whether the first cell is scheduled by the second cell according to a legacy (legacy) manner, for example, determine whether the identifier of the scheduling cell in the scheduling cell information is the same as the identifier of the second cell, if the identifier of the scheduling cell in the scheduling cell information is the same as the identifier of the second cell, further determine whether the value of the carrier indicator field used in the scheduling cell information is the same as the value of the CIF in the MC-DCI received in the second cell, and if the value of the carrier indicator field used in the scheduling cell information is the same as the CIF in the MC-DCI received in the second cell, determine that the MC-DCI received in the second cell is used to schedule the first cell.

It should be noted that, in the tables referred to in all the embodiments of the present disclosure, each element is independently present, and these elements are exemplarily listed in the same table, but do not mean that all the elements in the table must be present according to the table shown at the same time. The value of each element is independent of any other element value in the table. Therefore, it will be understood by those skilled in the art that the value of each element in the table is a separate embodiment.

In an implementation case, the network device may send the association carried by the RRC message to the terminal, may send the association carried by the RRC message to the terminal in other manners, for example, the association may be carried by a Media Access Control Element (MAC CE), and may also determine the association in a predefined manner.

In a case that the association relationship is carried in an RRC message and sent to the terminal, the association relationship may be specifically carried in scheduling cell information (scheduling cellinfo-r 18) of the RRC message, for example, in an embodiment, contents included in the scheduling cell information may be as follows:

in the case that the scheduling cell information indication value is other, the sequence (sequence) may include n indication combinations, where n is an integer greater than 1, each indication combination in the sequence includes a set of values of the carrier indication field and the scheduling cell identifier, and the n indication combinations (i.e., the values of the n carrier indication fields and the n scheduling cell identifiers) form the association relationship.

For a terminal that does not support multi-cell scheduling and a terminal that supports multi-cell scheduling, but when the received DCI is legacy DCI (e.g., DCI for scheduling a single cell), after receiving the association relationship, the two terminals may determine a cell scheduled by the received legacy DCI according to the existing scheduling cell information (scheduling cellinfo), or determine a cell scheduled by the received legacy DCI according to the association relationship in the scheduling cell information (which may be referred to as scheduling cellinfo-r 18) in this embodiment.

When determining a cell scheduled by the received legacy DCI according to the association relationship in the scheduling cell information in this embodiment, a single cell scheduled by the received legacy DCI may be determined by presetting the value of the carrier indication field in the indication combination and the scheduling cell identifier, for example, the single cell scheduled by the legacy DCI may be determined according to the value of the carrier indication field in the first indication combination and the scheduling cell identifiers (cif-in scheduling cell #1 and scheduling cell # 1).

In one embodiment, the content included in the scheduling cell information may be as follows:

in the scheduling cell information, n other(s) may be included, and the sequence (sequence) in each other(s) may include 1 indication combination, where the indication combination includes the value of a set of carrier indication fields and the scheduling cell id, and the sequence indication combination in the n other(s) (i.e., the value of the n carrier indication fields and the n scheduling cell ids) forms the association.

When determining the cell scheduled by the received legacy DCI according to the association relationship in the scheduling cell information in this embodiment, a single cell scheduled by the received legacy DCI may be determined by presetting an indication combination (including a value of a carrier indication field and a scheduling cell identifier) in an indicator value, for example, a single cell scheduled by the received legacy DCI may be determined according to a value of a carrier indication field in an indication combination in a first other (other # 1) and a scheduling cell identifier.

Fig. 4 is a schematic flow chart diagram illustrating yet another scheduling determination method according to an embodiment of the present disclosure. As shown in fig. 4, the method further comprises:

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

In one embodiment, when the CIF sizes in the DCI are different, the terminal may have different parsing manners for the DCI, and therefore, the terminal needs to determine the CIF size in the MC-DCI received in the second cell in order to accurately parse the MC-DCI.

Since there may be multiple values in the carrier indication field in the association relationship indicated to the terminal by the network device, the size of the CIF in the MC-DCI sent to the terminal by the network device needs to be sufficient to indicate the values of all the carrier indication fields. Therefore, the size of the CIF in the MC-DCI may be determined according to the range of the value of the carrier indication field in the association relationship corresponding to the serving cell, for example, the maximum value of the carrier indication field in the association relationship corresponding to the serving cell may be determined, the size of the carrier indication field in the MC-DCI may be determined according to the maximum value, for example, the maximum value is 7, the size of the CIF in the MC-DCI may be determined to be 3 bits, for example, the maximum value is 3, and the size of the CIF in the MC-DCI may be determined to be 2 bits.

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

determining the size of the carrier indication domain in the DCI according to the value range of the carrier indication domain of the serving cell under the condition that the value ranges of the carrier indication domains in the association relationship corresponding to the serving cell are the same;

and/or determining the size of the carrier indication domain in the DCI according to the maximum range of the value of the carrier indication domain in the association relationship corresponding to the serving cell under the condition that the ranges of the values of the carrier indication domains in the association relationship corresponding to the serving cell are different.

Under the condition that the value ranges of the carrier indication fields in the association relationship corresponding to the serving cell are the same, and the maximum values of the carrier indication fields in the association relationship corresponding to the serving cell are the same, the size of the CIF in the MC-DCI may be determined according to the value ranges of the carrier indication fields (e.g., the maximum values of the carrier indication fields). E.g., ranging from 0-3, the size of CIF in MC-DCI can be determined to be 2 bits; e.g., ranging from 0-7, the size of CIF in MC-DCI can be determined to be 3 bits.

In a case that ranges of values of carrier indication fields in the association relationship corresponding to the serving cell are different (for example, partially or completely different), the maximum value of the carrier indication fields in the association relationship corresponding to the serving cell may be different, and then the maximum range of the values of the carrier indication fields in the association relationship corresponding to the serving cell needs to be determined, so as to determine the size of the CIF in the MC-DCI according to the maximum range. For example, the range in the association relationship corresponding to cell 1 is 0 to 3, the range in the association relationship corresponding to cell 2 is 0 to 7, and the maximum range is 0 to 7, so that the size of CIF in MC-DCI can be determined to be 3 bits.

Fig. 5 is a schematic flow chart diagram illustrating an indication determination method in accordance with an embodiment of the present disclosure. The indication determining method shown in this embodiment may be executed by a terminal, where the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other communication devices. The terminal may communicate with network devices including, but not limited to, network devices in 4G, 5G, 6G, etc. communication systems, such as base stations, core networks, etc.

As shown in fig. 5, the indication determining method may include the steps of:

in step S501, determining an association relationship corresponding to a first cell, where the association relationship includes an association relationship between a value of a first information field and information indicated by the first information field for the first cell;

in step S502, receiving, in a second cell, downlink control information DCI for scheduling multiple cells, and determining a value of the first information field in the DCI;

in step S503, in a case that the first cell is scheduled by the DCI, determining, according to the association relationship, information that the first information field in the DCI indicates for the first cell.

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), frequency Domain Resource Assignment, ZP CSI-RS trigger (zero power channel state information reference signal trigger), downlink Assignment index (Downlink Assignment index), PUCCH Resource indicator (physical uplink control channel Resource indicator), PDSCH-to-HARQ feedback timing indicator (physical Downlink shared channel to hybrid automatic retransmission feedback timing indicator), antenna port(s), transmission configuration indication (SRS), request for listening reference signal, DMRS Transmission (demodulation reference signal sequence initialization).

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

In one embodiment, in the case of scheduling multiple cells through MC-DCI, the information field in the MC-DCI also needs to complete the indication for each of the multiple cells. For example, the MC-DCI received by the terminal in the second Cell #0, and the first Cell used by the MC-DCI for scheduling includes Cell #1 and Cell #2, it is necessary to determine the information indicated by the information field in the MC-DCI for Cell #1 and the information indicated for Cell # 2. For example, for BWP indicator in MC-DCI, the BWP identifier indicated by BWP indicator for Cell #1 and the BWP identifier indicated for Cell #2 need to be determined.

In the embodiment of the present disclosure, the network device may configure a corresponding association relationship for a serving cell (for example, a cell currently scheduled by MC-DCI or a cell that can be scheduled by MC-DCI), for example, after determining that an RRC message received by a first cell in the serving cell includes the association relationship, the network device may determine that the association relationship in the RRC message is the association relationship corresponding to the first cell.

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

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

the association relationship between the first information field and the information indicated by the first information field for the first cell may include an association relationship between values of a plurality of first information fields and information indicated by a plurality of first information fields for the first cell, for example, the value of the first information field is 0, the indication information is BWP identifier 2, the value of the first information field is 1, and the indication information is BWP identifier 3.

receiving a radio resource control, RRC, message at the first cell;

determining the association relationship in the RRC message.

The network device may send an RRC message to the terminal in the first cell, and the association relationship corresponding to the first cell is carried in the RRC message. After receiving the RRC message in the first cell, the terminal may determine, when determining that the RRC message carries the association relationship (for example, the association relationship between a value of the first information field included in the RRC message and information indicated by the first information field for the first cell), the association relationship in the RRC message as an association relationship corresponding to the first cell.

Fig. 6A is a schematic diagram illustrating an application scenario according to an embodiment of the present disclosure. Fig. 6B is a schematic diagram illustrating another application scenario according to an embodiment of the present disclosure.

As shown in fig. 6A, it is exemplified that the first Cell includes Cell #1 (Cell id is 1) and Cell #2 (Cell id is 2), the second Cell includes Cell #0 (Cell id is 0), and the first information field includes a BWP indicator.

The terminal determines that the MC-DCI received in Cell #0 schedules the first cells Cell #1 and Cell #2 and also schedules the second Cell #0. The association relationship carried in the RRC message sent by the Cell #0 to the terminal is table2-0, the association relationship carried in the RRC message sent by the Cell #1 to the terminal is table2-1, and the association relationship carried in the RRC message sent by the Cell #2 to the terminal is table2-2.

the table2-0, table2-1 and table2-2 contain the association relationship between the values of the plurality of first information fields and the information indicated by the plurality of first information fields for the first cell. For example, in table2-1, the BWP indicator in MC-DCI has a value of 00, the BWP ID in MC-DCI has a value of 2, the BWP indicator in MC-DCI has a value of 01, the BWP ID in MC-DCI has a value of 3, the BWP indicator in MC-DCI has a value of 10, the BWP ID in MC-DCI has a value of 2, and the BWP indicator in MC-DCI has a value of 11, and the BWP ID in MC-DCI has a value of 10.

When the MC-DCI received by the terminal 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 the BWP indicator with the value of 1 exists in table2-0, and further may determine that the information indicated by the BWP indicator with the value of 1 in table2-0 is BWP ID 2, thereby determining that the BWP ID indicated by the MC-DCI for Cell #0 is BWP ID 2; the terminal determines that a BWP indicator with a value of 1 exists in table2-1, and further determines that the information indicated by the BWP indicator with the value of 1 in table2-1 is BWP ID 3, thereby determining that the BWP ID indicated by MC-DCI for Cell #1 is 3; the terminal may determine that a BWP indicator having a value of 1 exists in table2-2, and may further determine that the BWP indicator having a value of 1 indicates a BWP ID of 1 in table2-2, thereby determining that the BWP ID indicated by the MC-DCI for Cell #2 is 1.

As shown in fig. 6B, for example, the first Cell includes Cell #1 (Cell id is 1) and Cell #2 (Cell id is 2), the second Cell includes Cell #0 (Cell id is 0), and the first information field includes ZP CSI-RS trigger.

The terminal determines that the MC-DCI received in Cell #0 schedules the first cells Cell #1 and Cell #2 and also schedules the second Cell #0. The association relationship carried in the RRC message sent by the network device to the terminal by the Cell #0 is table3-0, the association relationship carried in the RRC message sent by the Cell #1 to the terminal is table3-1, the association relationship is not carried in the RRC message sent by the Cell #2 to the terminal, or the carried association relationship is table3-2, but table3-2 is blank and indicates that the corresponding BWP is not configured.

the table3-0 and the table3-1 contain the association relationship between the values of the plurality of first information fields and the information indicated by the plurality of first information fields for the first cell. For example, in table3-1, the value of ZP CSI-RS trigger in MC-DCI is 00, the indicated information is reserved (reserved), the value of ZP CSI-RS trigger in MC-DCI is 01, and the indicated information is ZP CSI-RS resource set ID is 1.

When the MC-DCI received by the terminal in Cell #0, if the terminal determines that the value of the ZP CSI-RS trigger in the MC-DCI is 01 (namely 1), further, the terminal determines that the ZP CSI-RS trigger with the value of 1 exists in table3-0, and further can determine that the information, indicated by the ZP CSI-RS trigger with the value of 1, in table3-0 is the ZP CSI-RS resource set ID as reservation, so that the MC-DCI is determined to be reserved for the ZP CSI-RS resource set ID indicated by Cell # 0; the terminal determines that the ZP CSI-RS trigger with the value of 1 exists in table3-1, and then the information, indicated by the ZP CSI-RS trigger with the value of 1, in table3-1 is determined that the ZP CSI-RS resource set ID is 1, so that the ZP CSI-RS resource set ID indicated by MC-DCI for Cell #1 is determined to be 1.

It should be noted that, in fig. 6A and 6B, the values of the first information field are arranged from 00 to 11, but in a specific application, the arrangement of the values of the first information field in the table may be set as required, for example, from 11 to 00, or may not be monotonically increased or decreased from top to bottom, for example, from top to bottom to 10, 01, 00, 11.

In an implementation case, the network device may send the association carried by the RRC message to the terminal, and may send the association carried by the RRC message to the terminal in other manners, for example, the association may be carried in the MAC CE and sent to the terminal.

When the association relationship is carried in the RRC message and sent to the terminal, taking the BWP indicator as the first information as an example, the RRC message may include n indication combinations, where n is an integer greater than 1, each indication combination includes a set of BWP indicator values and a BWP ID, and the n indication combinations (that is, the BWP indicator values and the BWP ID) form the association relationship.

For a terminal that does not support multi-cell scheduling and a terminal that supports multi-cell scheduling, but the received DCI is legacy DCI (e.g., DCI for scheduling a single cell), after receiving the association relationship, the two terminals may determine, according to the value of the BWP indicator in the preset indication group and the BWP ID, a BWP ID indicated by the BWP indicator in the received DCI for the first cell, for example, may determine, according to the value of the BWP indicator in the first indication group and the BWP ID, a BWP ID indicated by the BWP indicator in the received DCI for the first cell.

It should be noted that, when the terminal does not receive the association relationship in the RRC message received in all cells scheduled by the MC-DCI, the information indicated by the first information field for the first cell may be determined according to a legacy (legacy) manner.

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

The reference cell may be determined according to a predefined rule, for example, to identify a largest or smallest cell for the second cell, or for a cell currently scheduled by MC-DCI or a cell that can be scheduled.

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

When the association relationship is not determined in the RRC message received by the terminal in all cells scheduled by the MC-DCI, the information indicated by the first information field for the reference cell may be determined first. For example, the first information field BWP indicator has a value of 11 and the indicated information for the second cell (e.g., cell 0) has a BWP ID of 4.

Then, the configuration parameters related to the first information field in the RRC message received by each first cell may be determined, and the information indicated by the first information field in the MC-DCI for the first cell is determined according to the configuration parameters related to the first information field in the RRC message received by the first cell and the value of the first information field in the MC-DCI.

If the configuration parameter related to the first information field in the RRC message received in the first cell is greater than or equal to the range of the value of the information indicated by the first information field for the reference cell, it may 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 the cell 1 is the first cell scheduled by the MC-DCI, and the number of BWPs configured in the RRC message received by the cell 1 is greater than or equal to 4, it may be determined that the information indicated by the BWP indicator for the cell 1 in the MC-DCI is the same as the information indicated for the cell 0, that is, the information indicated for the cell 1 is also the BWP ID of 4.

If the configuration parameter associated with the first information field in the RRC message received in the first cell is smaller than the value of the information indicated by the first information field for the reference cell, it may be determined that the first information field in the MC-DCI is not indicated for the first cell, or it may be determined that the value of the information indicated by the first information field in the MC-DCI for the first cell is equal to the maximum value of the configuration parameter associated with the first information field in the RRC message received in the first cell. For example, if the cell 2 is the first cell scheduled by the MC-DCI, and the number of BWPs configured in the RRC message received by the cell 2 is equal to 2 (the maximum value is 2), it may be determined that the BWP indicator in the MC-DCI does not indicate the cell 2, or that the BWP ID indicates that the BWP indicator in the MC-DCI indicates the BWP ID is 2.

Fig. 7 is a schematic flow chart diagram illustrating another method of schedule determination in accordance with an embodiment of the present disclosure. As shown in fig. 6, the method further comprises:

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

In one embodiment, the resolution mode of the terminal may be different when the first information field in the DCI is different in size, and 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 resolution accurately.

Since there may be multiple values in the first information field in the association relationship 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 the first information fields in the association relationship. Therefore, the size of the CIF in the MC-DCI may be determined according to the range of the value of the first information field in the association relationship corresponding to the serving cell, for example, the maximum value of the first information field in the association relationship corresponding to the serving cell may be determined, the size of the carrier indication field in the MC-DCI may be determined according to the maximum value, for example, the maximum value is 1, the size of the CIF in the MC-DCI may be determined to be 1 bit, for example, the maximum value is 3, and the size of the CIF in the MC-DCI may be determined to be 2 bits.

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

under the condition that the value ranges of the first information domains in the incidence relation corresponding to the serving cell are the same, determining the size of the first information domain in the DCI according to the value range of the first information domain of the serving cell;

and/or under the condition that the value ranges of the first information domain in the association relationship corresponding to the serving cell are different, determining the size of the first information domain in the DCI according to the maximum value range of the first information domain in the association relationship corresponding to the serving cell.

In a case that the range of the value of the first information field in the association relationship corresponding to the serving cell is the same, and the maximum value of the first information field in the association relationship corresponding to the serving cell is the same, the size of the CIF in the MC-DCI may be determined according to the range of the value of the first information field (for example, the maximum value of the first information field). E.g., ranging from 0 to 1, the size of the first information field in the MC-DCI may be determined to be 1 bit; e.g., ranging from 0-3, the size of the first information field in the MC-DCI may be determined to be 2 bits.

Under the condition that the ranges of the values of the first information domains in the association relationship corresponding to the serving cell are different, the maximum value of the first information domain in the association relationship corresponding to the serving cell may be different, so that the maximum range of the values of the first information domain in the association relationship corresponding to the serving cell needs to be determined, and the size of the first information domain in the MC-DCI is further determined according to the maximum range. For example, the range in the association relationship corresponding to cell 1 is 0-1, the range in the association relationship corresponding to cell 2 is 0-3, and the maximum range is 0-3, so that the size of CIF in MC-DCI can be determined to be 2 bits.

Fig. 8 is a schematic flow chart diagram illustrating an association indication method according to an embodiment of the present disclosure. The association relation indication method shown in this embodiment may be executed by a network device, where the network device may communicate with a terminal, the network device includes, but is not limited to, a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station, and the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other communication apparatuses.

As shown in fig. 8, the association relationship indicating method may include the following steps:

in step S801, an association relationship corresponding to the first cell is indicated to the terminal, where the association relationship includes an association relationship between a value of the carrier indication field and a scheduling cell identifier.

It should be noted that the network device may send the RRC message to the terminal in multiple first cells, and each first cell may have a corresponding association relationship. The association relations corresponding to different first cells may be different or the same, and may be specifically configured as required.

the association relationship table between the carrier indication domain and the scheduling cell identifier may include an association relationship between values of a plurality of carrier indication domains and one scheduling cell identifier, for example, a value of a carrier indication domain is 1, a corresponding scheduling cell identifier is 0, a value of a carrier indication domain is 2, and a corresponding scheduling cell identifier is 0;

According to the embodiment of the disclosure, the network device may determine an association relationship between the value of the carrier indication field corresponding to each first cell and the scheduling cell identifier, and indicate the association relationship to the terminal, and since the association relationship may define a correspondence relationship between the values of the multiple carrier indication fields and the multiple scheduling cell identifiers, and is not limited to associating one scheduling cell identifier with the value of one carrier indication field, when the subsequent network device sends MC-DCI to the terminal according to the association relationship, the scheduling flexibility of the MC-DCI for the first cell may be improved. For example, the network device may set a CIF value in the transmitted MC-DCI according to the association relationship corresponding to the first cell to be scheduled, so as to dynamically adjust the scheduled multiple cells (cell combinations).

For example, in the association relationship, the value of the carrier indication field is 1, the corresponding scheduling cell identifier is 0, the value of the carrier indication field is 2, and the corresponding scheduling cell identifier is 0. Then, the network device may implement scheduling for the first cell when the value of CIF in MC-DCI sent to the terminal in the second cell with cell identifier 0 is 1, and may also implement scheduling for the first cell when the value of CIF in MC-DCI sent to the terminal in the second cell with cell identifier 0 is 2.

Fig. 9 is a schematic flow chart diagram illustrating another incidence relation indication method according to an embodiment of the present disclosure. As shown in fig. 9, the method further includes:

in step S901, determining that the first cell is scheduled through DCI for scheduling multiple cells sent in a second cell, and determining a first value of a carrier indication field corresponding to an identifier of the second cell according to the association relationship;

in step S902, the DCI is transmitted to the terminal in the second cell, where the value indicating the field in the DCI is equal to the first value.

In an embodiment, after indicating the association relationship to the terminal, when it is required to schedule the first cell by sending MC-DCI in the second cell, the network device may determine, according to the association relationship, a first value of a carrier indication field corresponding to the identifier of the second cell, and then may set, in the MC-DCI sent by the second cell to the terminal, a value of a CIF in the MC-DCI to be equal to the first value. After the terminal receives the MC-DCI in the second cell, it may determine that the scheduling cell identifier corresponding to the first value of the CIF in the MC-DCI in the association is the same as the identifier of the second cell, thereby determining that the first cell is the cell scheduled by the MC-DCI.

In an embodiment, the sending, to the terminal, the association corresponding to the first cell includes: and sending an RRC message to the terminal in the first cell, wherein the association relationship is carried in the RRC message.

The network device may send an RRC message to the terminal in the first cell, and the association relationship corresponding to the first cell is carried in the RRC message. After receiving the RRC message in the first cell, the terminal may determine, when determining that the RRC message carries the association relationship (for example, the RRC message includes an association relationship between a value of the carrier indication field and the scheduling cell identifier), the association relationship in the RRC message as an association relationship corresponding to the first cell.

In one embodiment, the method further comprises: determining an indication value of scheduling cell information in the RRC message; and carrying the association relation in the RRC message under the condition that the indicated value of the scheduling cell information is other.

The network device may include scheduling cell information in the cross-carrier scheduling configuration of the RRC message sent by the first cell to the terminal, and the scheduling cell information may include multiple types of data, for example, selection (choice), sequence (sequence), boolean (boolean), integer, floating point, and the like, where an indication value of the "selection" type of data may be itself (own) or others (other). In all embodiments of the present disclosure, the indication value of the scheduling cell information may refer to an indication value of "selection" type data in the scheduling cell information.

In the case where the indication value of the scheduling cell information is self (own), it indicates that the first cell may be scheduled by DCI transmitted in the first cell, but not by DCI transmitted in other cells (e.g., the second cell). It can be seen that, in this case, it has been determined that the first cell is only scheduled by the DCI received by the terminal in the first cell, so the network device does not need to carry the association relationship of multi-cell scheduling in the RRC message.

In the case that the indication value of the scheduling cell information is other (other), it indicates that the first cell may be scheduled by DCI transmitted in other cells (cross-carrier scheduling), and it is seen that in this case, the terminal still needs to determine in which cell the first cell is scheduled by DCI received by the terminal, so the network device may carry the association in an RRC message, so that the terminal determines whether the first cell is scheduled by MC-DCI received by the terminal in the second cell. The value of the carrier indication field in the association relationship may be a value of a carrier indication field (which may be referred to as cif-scheduling cell-r 18) used in a scheduling cell in the scheduling cell information in the RRC message.

In one embodiment, the method further comprises: determining the size of the carrier indication domain in the DCI according to the value of the carrier indication domain in the association relationship corresponding to the serving cell; the serving cell includes a cell currently scheduled by the DCI or a cell that can be scheduled by the DCI, and the cell that can be scheduled by the DCI may be defined in a set form.

In one embodiment, the resolution of the terminal may be different for CIFs in the DCI with different sizes, and therefore, the terminal needs to determine the size of the CIF in the MC-DCI received in the second cell in order to perform resolution accurately.

Since there may be multiple values in the carrier indication field in the association relationship indicated by the network device to the terminal, the size of the CIF in the MC-DCI sent by the network device to the terminal needs to be sufficient to indicate the values of all the carrier indication fields. Therefore, the size of the CIF in the MC-DCI may be determined according to the value of the carrier indication field in the association relationship corresponding to the serving cell, for example, the maximum value of the carrier indication field in the association relationship corresponding to the serving cell may be determined, the size of the carrier indication field in the MC-DCI may be determined according to the maximum value, for example, the maximum value is 7, the size of the CIF in the MC-DCI may be determined to be 3 bits, for example, the maximum value is 3, and the size of the CIF in the MC-DCI may be determined to be 2 bits.

In an embodiment, the determining, according to the value of the carrier indication field in the association received in the serving cell, the size of the carrier indication field in the DCI includes:

under the condition that the value ranges of the carrier indication domains in the association relationship corresponding to the serving cell are the same, determining the size of the carrier indication domain in the DCI according to the value ranges of the carrier indication domains;

Under the condition that the ranges of the values of the carrier indication fields in the association relationship corresponding to the serving cell are different, the maximum value of the carrier indication fields in the association relationship corresponding to the serving cell may be different, and then the maximum range of the values of the carrier indication fields in the association relationship corresponding to the serving cell needs to be determined, so as to determine the size of the CIF in the MC-DCI according to the maximum range. For example, the range in the association relationship corresponding to the cell 1 is 0 to 3, the range in the association relationship corresponding to the cell 2 is 0 to 7, and the maximum range is 0 to 7, so that the size of the CIF in the MC-DCI can be determined to be 3 bits.

Fig. 10 is a schematic flow chart diagram illustrating an association indication method according to an embodiment of the present disclosure. The association indication method shown in this embodiment may be executed by a network device, where the network device may communicate with a terminal, the network device includes but is not limited to a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station, and the terminal includes but is not limited to a communication device such as a mobile phone, a tablet computer, a wearable device, a sensor, and an internet of things device.

As shown in fig. 10, the association relationship indicating method may include the following steps:

in step S1001, an association relationship corresponding to a first cell is indicated to a terminal, where the association relationship includes an association relationship between a value of a first information field and information indicated by the first information field for the first cell.

In one embodiment, in the case of scheduling multiple cells through MC-DCI, the information field in the MC-DCI also needs to complete the indication for each of the multiple cells. For example, in the second Cell #0, MC-DCI is transmitted to the terminal, and the first Cell for scheduling includes Cell #1 and Cell #2, information indicated by the information field in the MC-DCI for Cell #1 and information indicated for Cell #2 need to be determined. For example, for the BWP indicator in the MC-DCI, the BWP identifier indicated by the BWP indicator for Cell #1 and the BWP identifier indicated for Cell #2 need to be determined.

It should be noted that the terminal may receive the RRC message in multiple first cells, and each first cell may have a corresponding association relationship. The association relations corresponding to different first cells may be different or the same, and may be specifically configured as required.

The association relationship between the first information field and the information indicated by the first information field for the first cell may include an association relationship between a value of the first information field and information indicated by the first information field for the first cell, and may be carried in an RRC message in a form of a table (table).

According to the embodiment of the disclosure, the network device may determine an association relationship between a value of a first information field corresponding to each first cell and information indicated by the first information field for the first cell, and indicate the association relationship to the terminal, so that after the second cell receives MC-DCI, the terminal may determine the information indicated by the information field in the MC-DCI for each first cell according to the association relationship. Since the association relationship is configured for each first cell allocation, the association relationship corresponding to each first cell may be different, which facilitates flexible adjustment of the information indicated by the MC-DCI for each first cell.

Fig. 11 is a schematic flow chart diagram illustrating another incidence relation indication method according to an embodiment of the present disclosure. As shown in fig. 11, the method further includes:

in step S1101, determining first information indicated to a first cell by a first information field in DCI for scheduling multiple cells transmitted in a second cell, and determining a value of the first information field corresponding to the first information according to the association relationship;

in step S1102, the DCI is sent to the terminal in the second cell, where a value of a first information field in the DCI is equal to a value of a first information field corresponding to the first information in the association relationship.

In an embodiment, after indicating the association relationship to the terminal, when first information indicated for the first cell through the first information field is needed, the network device may determine, according to the association relationship, a value of the first information field corresponding to the first information, and then in MC-DCI sent by the second cell to the terminal, may set the value of the first information field in the MC-DCI to be equal to the value of the first information field corresponding to the first information in the association relationship. After the terminal receives the MC-DCI in the second cell, the terminal may determine first information corresponding to the value of the first information field in the MC-DCI in the association relationship, so as to determine that the information indicated by the first information field in the MC-DCI for the first cell is the first information.

In one embodiment, the method further comprises: determining the size of a first information domain in the DCI according to the value of the first information domain in the association relation corresponding to a serving cell; the serving cell includes a cell currently scheduled by the DCI or a cell that can be scheduled by the DCI, and the cell that can be scheduled by the DCI may be defined in a set form.

Since there may be multiple values in the first information field in the association relationship indicated to the terminal by the network device, the size of the first information field in the MC-DCI sent to the terminal by the network device needs to be sufficient to indicate the values of all the first information fields in the association relationship. Therefore, the size of the CIF in the MC-DCI may be determined according to the range of the value of the first information field in the association relationship corresponding to the serving cell, for example, the maximum value of the first information field in the association relationship corresponding to the serving cell may be determined, the size of the carrier indication field in the MC-DCI may be determined according to the maximum value, for example, the maximum value is 1, the size of the CIF in the MC-DCI may be determined to be 1 bit, for example, the maximum value is 3, and the size of the CIF in the MC-DCI may be determined to be 2 bits.

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

determining the size of a first information domain in the DCI according to the value range of the first information domain of the serving cell under the condition that the value range of the first information domain in the association relationship corresponding to the serving cell is the same;

and/or determining the size of the first information domain in the DCI according to the maximum range of the value of the first information domain in the association relationship corresponding to the serving cell under the condition that the ranges of the values of the first information domain in the association relationship corresponding to the serving cell are different.

In a case that the value ranges of the first information fields in the association relationship corresponding to the serving cell are the same, and the maximum value of the first information fields in the association relationship corresponding to the serving cell is the same, the size of the CIF in the MC-DCI may be determined according to the value ranges of the first information fields (e.g., the maximum value of the first information fields). E.g., ranging from 0-1, the size of the first information field in the MC-DCI may be determined to be 1 bit; e.g., ranging from 0-3, the size of the first information field in the MC-DCI may be determined to be 2 bits.

Under the condition that the ranges of the values of the first information fields in the association relationship corresponding to the serving cell are different, the maximum value of the first information field in the association relationship corresponding to the serving cell may be different, so that the maximum range of the values of the first information field in the association relationship corresponding to the serving cell needs to be determined, and further, the size of the first information field in the MC-DCI is determined according to the maximum range. For example, the range in the association relationship corresponding to the cell 1 is 0 to 1, the range in the association relationship corresponding to the cell 2 is 0 to 3, and the maximum range is 0 to 3, so that the size of the CIF in the MC-DCI can be determined to be 2 bits.

The network device may send an RRC message to the terminal in the first cell, and carry the association relationship corresponding to the first cell in the RRC message. After receiving the RRC message in the first cell, the terminal may determine, when determining that the RRC message carries the association relationship (for example, the RRC message includes a table of association relationships between values of the first information field and information indicated by the first information field for the first cell), the association relationship in the RRC message as an association relationship corresponding to the first cell.
