[0022] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0024] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0025] For the purpose of brevity and ease of understanding, the terms "greater than," "less than," "higher than," and "lower than" are used herein to describe size relationships. However, those skilled in the art will understand that the term "greater than" also encompasses the meaning of "greater than or equal to," and "less than" also encompasses the meaning of "less than or equal to," and the term "higher than" also encompasses the meaning of "higher than or equal to," and "lower than" also encompasses the meaning of "lower than or equal to."

[0026] Figure 1A This is a schematic flow chart illustrating a method for determining scheduling information according to an embodiment of the present disclosure. The scheduling information determination method illustrated in this embodiment can be applied to terminals, including but not limited to mobile phones, tablets, wearable devices, sensors, IoT devices, and other communication devices. The terminals can communicate with network devices, including but not limited to network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0027] like Figure 1A As shown, the scheduling information determination method may include the following steps:

[0028] In step S101, downlink control information DCI for scheduling multiple cells sent by a network device is received;

[0029] In step S102, a first association relationship between a value of a specific information field in the DCI and a plurality of scheduling information, and a second association relationship between the plurality of scheduling information and a plurality of scheduled cells are determined;

[0030] In step S103, scheduling information of each scheduled cell is determined according to the first association relationship and the second association relationship.

[0031] In one embodiment, the DCI may include multiple types of information fields, such as the FDRA (Frequency Domain Resource Assignment) field, the ZP CSI-RS trigger (Zero Power Channel Information Reference Signal trigger) field, the BandWidth Part indicator field, etc.

[0032] For DCI of the existing mechanism, one type of information field can schedule a cell. For example, the FDRA information field can schedule the frequency domain resources of the target cell.

[0033] This embodiment can be applied in a scenario where a DCI schedules multiple cells. In this embodiment, the network device can send DCI to the terminal for scheduling multiple cells (i.e., scheduled cells). Specifically, the value of a specific information field in the DCI (the value of a certain information field, not the values ​​of multiple information fields) can be associated with multiple scheduling information (i.e., the value of one information field is associated with multiple scheduling information), for example, referred to as a first association relationship, and an association relationship can be established between multiple scheduling information and multiple scheduled cells, for example, referred to as a second association relationship. The multiple scheduling information types corresponding to the values ​​of one type of information field are the same, for example, corresponding to the frequency domain resources FDRA of different cells, for example, corresponding to the BWP indexes configured for different cells, as described below.

[0034] This indication method may be referred to as a combined or shared indication. For example, a specific value indicated by a specific type of information field in a DCI may be associated with multiple scheduling information, and the multiple scheduling information may be associated with multiple scheduled cells.

[0035] The first association relationship can be determined in a predefined manner or in a signaling indication manner. Taking the signaling indication method as an example, the network side can define the first association relationship between the specific value indicated by the DCI specific type information field and multiple scheduling information based on the signaling indication (such as radio resource control RRC signaling). The signaling can be the signaling configured by the cell where the DCI is received. Taking RRC signaling as an example, the terminal receives the corresponding RRC signaling in the cell where the DCI is received, and the RRC signaling indicates the association relationship between the specific value indicated by the DCI specific type information field and multiple scheduling information. Among them, the number of bits occupied by the specific type information field is related to the range of the indication value configured by the RRC signaling.

[0036] Figure 1B FIG. 1 is a schematic diagram of an application scenario of a method for determining scheduling information according to an embodiment of the present disclosure. Figure 1B As shown, taking the BWP indication field as an example, in a DCI used to schedule three cells (cell ID numbers are 0, 1 and 2 respectively), the corresponding DCI is received in cell 0.

[0037] For example, the first association relationship is determined by signaling indication, and the terminal receives the corresponding RRC signaling in cell 0 to determine the first association relationship between the value of the BWP indication field in the DCI used to schedule multiple cells and the BWP IDs configured in multiple cells. For example, for the BWP indication field, the first association relationship can be shown in the following Table 1:

[0038]

[0039] Table 1

[0040] As shown in Table 1, the number of bits occupied by the BWP indicator field is log2(4)=2. In the scenario where the value of the BWP indicator field is 01, according to the first association relationship, it can be determined that the value of the BWP indicator field 01 is associated with three scheduling information, the first scheduling information is BWPid=2, the second scheduling information is BWP id=3, and the third scheduling information is BWP id=1. Furthermore, according to the second association relationship, it can be determined that the first scheduling information is associated with cell 0, the second scheduling information is associated with cell 1, and the third scheduling information is associated with cell 2. Therefore, it can be determined that BWP id=2 of cell 0, BWP id=3 of cell 1, and BWP id=1 of cell 2.

[0041] For the information field of the characteristic type in the DCI that schedules multiple cells, the value of the information field can be associated with the scheduling information There are n scheduling information in total, where n is equal to the number of scheduled cells. is the scheduling information of cell k1, is cell k jScheduling information, and so on. is cell k n Scheduling information, where k j The cell ID number.

[0042] The terminal can determine the first association relationship between the value of a specific information field in the DCI and multiple scheduling information, and the second association relationship between multiple scheduling information and multiple scheduled cells. Then, based on the first association relationship, the multiple scheduling information corresponding to the value of the specific information field in the DCI can be determined, and based on the second association relationship, the scheduled cell corresponding to each scheduling information can be determined, and then the scheduling information of each scheduled cell can be determined. Therefore, on the basis that the network device schedules multiple cells through one DCI, the terminal can accurately interpret the scheduling information of each cell indicated by the DCI. The above mainly introduces the specific implementation method of the first association relationship, and the determination relationship corresponding to the second association relationship will be expanded below.

[0043] It should be noted that regarding the multiple cells scheduled by DCI, that is, the multiple scheduled cells, the terminal can determine them based on the CIF (Cell Indicator Field) in the DCI, or it can be pre-agreed with the network device, or it can be determined according to predefined rules (such as protocol agreements), and this disclosure does not limit it.

[0044] In one embodiment, determining the first association between the value of the specific information field in the DCI and the plurality of scheduling information includes: determining the first association based on an instruction from a network device. For example, the network device may determine the association between the value of an information field (a specific information field, not multiple information fields) in the DCI and the plurality of scheduling information, and then indicate it to the terminal via RRC (Radio Resource Control) signaling. Of course, the association may also be determined based on predefined rules, such as based on protocol agreements.

[0045] In one embodiment, determining the second association relationship between the plurality of scheduling information and the plurality of scheduled cells includes: determining the second association relationship according to a predefined rule.

[0046] The first association relationship between the value of a specific information field in the DCI and multiple scheduling information, and the second association relationship between the multiple scheduling information and multiple scheduled cells, may be specified by a predefined rule, such as a protocol agreement; or may be indicated by a network device, wherein the manner in which the network device indicates the association relationship includes but is not limited to indication through RRC signaling, indication through DCI, and indication through MAC CE (Media Access Control Control Element). The number of bits occupied by the information field in the DCI is determined by the number of values ​​determined based on the signaling indication or in a predetermined manner. For example, if the first association relationship defines the values ​​of N information fields, and the value of each information field is associated with multiple scheduling information, then the number of bits occupied by the information field in the DCI is equal to log2(N).

[0047] The following embodiments are mainly used to exemplify the case where the second association relationship is specified by a predefined rule.

[0048] In one embodiment, the multiple scheduling information includes n scheduling information, and the multiple scheduled cells include n scheduled cells; the predefined rule stipulates that the jth scheduling information among the n scheduling information is associated with the jth scheduled cell among the n scheduled cells, where 1≤j≤n.

[0049] The scheduled cells may include the cell in which the terminal receives the DCI and other cells (cells other than the cell in which the terminal receives the DCI among the scheduled cells), or may exclude the cell in which the terminal receives the DCI and only include other cells. In this implementation, the predefined rules may not distinguish between the cell in which the terminal receives the DCI and other cells when specifying the association between the scheduled cells and the scheduling information, and the association between the cell in which the terminal receives the DCI and other cells and the scheduling information may be specified according to the same rules.

[0050] Taking n scheduled cells as an example, n scheduling information can be determined based on the first association relationship and the value of the information field in the DCI, and the correspondence between the n scheduling information and the n scheduled cells can be determined based on the second association relationship. The second association relationship can be that the jth scheduling information in the n scheduling information is associated with the jth scheduled cell in the n scheduled cells.

[0051] Based on this, the terminal can determine that the jth scheduling information is the scheduling information of the jth scheduled cell, so that on the basis that the network device schedules multiple cells through one DCI, the terminal can accurately interpret the scheduling information of each cell indicated by the DCI.

[0052] For example, for the n scheduled cells from the first cell to the nth scheduled cell, taking the FDRA field using the combine indication mode as an example, n scheduling information can be determined according to the value of the FDRA field and the first association relationship, for example to where k j In this embodiment, the terminal can determine, based on the second association relationship, that the first scheduling information is the frequency domain scheduling information of the first scheduled cell (cell k1), the second scheduling information is the frequency domain scheduling information of the second scheduled cell (cell k2), ..., the jth scheduling information is the frequency domain scheduling information of the jth scheduled cell (cell k j ) frequency domain scheduling information, ..., nth scheduling information is the frequency domain scheduling information of the nth scheduled cell (cell k n ), so that on the basis of scheduling multiple cells through one DCI, the terminal can accurately interpret the frequency domain scheduling information of each cell indicated by the DCI.

[0053] For example, for the n scheduled cells from the first cell to the nth scheduled cell, taking the ZP CSI-RS trigger field using the combine indication mode as an example, n scheduling information can be determined according to the value of the ZP CSI-RS trigger field and the first association relationship, for example to where k j In this embodiment, the terminal can determine, based on the second association relationship, that the first scheduling information is the ZP CSI-RS trigger information of the first scheduled cell (cell k1), the second scheduling information is the ZP CSI-RS trigger information of the second scheduled cell (cell k2), ..., the jth scheduling information is the ZP CSI-RS trigger information of the jth scheduled cell (cell k j ) ZP CSI-RS trigger information, ..., nth scheduling information for the nth scheduled cell (cell k n ), so that on the basis of scheduling multiple cells through one DCI, the terminal can accurately interpret the ZP CSI-RS trigger information of each cell indicated by the DCI.

[0054] For example, for n scheduled cells from the first cell to the nth scheduled cell, taking the BWP indication field adopting the combine indication mode as an example, n scheduling information can be determined according to the value of the BWP indication field and the first association relationship, for example to where k jIn this embodiment, the terminal can determine, based on the second association relationship, that the first scheduling information is the BWP information of the first scheduled cell (cell k1), the second scheduling information is the BWP information of the second scheduled cell (cell k2), ..., the jth scheduling information is the BWP information of the jth scheduled cell (cell k j ) BWP information, ..., nth BWP scheduling information is the nth scheduled cell (cell k n ), so that on the basis of scheduling multiple cells through one DCI, the terminal can accurately interpret the BWP information of each cell indicated by the DCI.

[0055] The order of the multiple scheduled cells will be determined in the subsequent embodiments.

[0056] The following describes, through several embodiments, how to determine the order of multiple scheduled cells by predefined rules that specify the association between the cell where the terminal receives the DCI and other cells and the information domain according to the same rule.

[0057] In one embodiment, the predefined rule stipulates that the identifier of the jth scheduled cell is smaller than the identifier of the j+1th scheduled cell, for example, j Less than k j+1 Or, the predefined rule stipulates that the identifier of the jth scheduled cell is greater than the identifier of the j+1th scheduled cell, for example, k j Greater than k j+1 .

[0058] In one implementation, the terminal may determine the identifier of the scheduled cell (e.g., Cell ID) based on RRC signaling sent by the network device, for example, based on information elements (IEs) such as ServcellIndex and / or SCellIndex in the RRC signaling. If the cell identifier corresponds to a PCI (Physical Cell Identity), the identifier may be determined based on the information element PhysCellId in the RRC signaling. Alternatively, the identifier may be determined based on other signaling. Alternatively, the identifier may be determined in other ways, for example, based on predefined rules.

[0059] The predefined rules may specify that the scheduled cells are sorted according to their identifiers. For example, they may be sorted from small to large according to their identifiers, so that the identifier of the jth scheduled cell is smaller than the identifier of the j+1th scheduled cell, or they may be sorted from large to small according to their identifiers, so that the identifier of the jth scheduled cell is larger than the identifier of the j+1th scheduled cell.

[0060] For example, take 4 scheduled cells as an example, which are cell #1 with ID 1, cell #2 with ID 2, cell #3 with ID 3 and cell #4 with ID 4. If they are sorted from small to large according to ID, then k j Less than k j+1 , we can determine that the first cell is cell #1, the second scheduled cell is cell #2, the third cell is cell #3, and the fourth cell is cell #4; if we sort them from large to small according to the identifier, then k j Greater than k j+1 , it can be determined that the first cell is cell #4, the second scheduled cell is cell #3, the third cell is cell #2, and the fourth cell is cell #1.

[0061] Based on this, the order of the cells can be accurately determined according to the cell identifiers, and further, it can be determined that the j-th information field is specifically the scheduling information of the j-th scheduled cell.

[0062] In one embodiment, the predefined rule stipulates that the center frequency of the jth scheduled cell is less than the center frequency of the j+1th scheduled cell; or, the predefined rule stipulates that the center frequency of the jth scheduled cell is greater than the center frequency of the j+1th scheduled cell.

[0063] Regarding the center frequency of the scheduled cell, the terminal can determine it based on the information sent by the network device, for example, based on the synchronization signal block SSB (Synchronization Signal Block) sent by the network device; of course, it can also be determined in other ways, for example, it can be specified by predefined rules.

[0064] The predefined rules may specify that the scheduled cells are sorted according to their center frequencies. For example, they may be sorted from small to large according to their center frequencies, so that the center frequency of the jth scheduled cell is less than the center frequency of the j+1th scheduled cell, or they may be sorted from large to small according to their center frequencies, so that the center frequency of the jth scheduled cell is greater than the center frequency of the j+1th scheduled cell.

[0065] For example, take four scheduled cells: cell #1 has a center frequency of f1, cell #2 has a center frequency of f2, cell #3 has a center frequency of f3, and cell #4 has a center frequency of f4, where f1 > f2 > f3 > f4. If the cells are sorted by center frequency in ascending order, the first cell is cell #4, the second scheduled cell is cell #3, the third cell is cell #2, and the fourth cell is cell #1. If the cells are sorted by center frequency in descending order, the first cell is cell #1, the second scheduled cell is cell #2, the third cell is cell #3, and the fourth cell is cell #4.

[0066] Based on this, the order of the cells can be accurately determined according to the center frequencies of the cells, and the j-th information field can be specifically the scheduling information of the j-th scheduled cell.

[0067] In one embodiment, the predefined rule stipulates that the absolute radio frequency channel number ARFCN corresponding to the center frequency of the j-th scheduled cell is less than the ARFCN corresponding to the center frequency of the j+1-th scheduled cell; or, the predefined rule stipulates that the ARFCN corresponding to the center frequency of the j-th scheduled cell is greater than the ARFCN corresponding to the center frequency of the j+1-th scheduled cell.

[0068] Regarding the ARFCN of the scheduled cell, the terminal may determine it according to the center frequency of the scheduled cell or by other means.

[0069] The predefined rules may specify that the scheduled cells are sorted according to the ARFCN of the scheduled cells. For example, they may be sorted from small to large according to ARFCN, so that the ARFCN of the j-th scheduled cell is smaller than the ARFCN of the j+1-th scheduled cell, or they may be sorted from large to small according to ARFCN, so that the ARFCN of the j-th scheduled cell is larger than the ARFCN of the j+1-th scheduled cell.

[0070] For example, taking four scheduled cells, the ARFCN of cell #1 is ARFCN#1, the ARFCN of cell #2 is ARFCN#2, the ARFCN of cell #3 is ARFCN#3, and the ARFCN of cell #4 is ARFCN#4. Here, ARFCN#1 > ARFCN#2 > ARFCN#3 > ARFCN#4. If sorted by ARFCN from smallest to largest, the first cell is cell #4, the second scheduled cell is cell #3, the third cell is cell #2, and the fourth cell is cell #1. If sorted by ARFCN from largest to smallest, the first cell is cell #1, the second scheduled cell is cell #2, the third cell is cell #3, and the fourth cell is cell #4.

[0071] Accordingly, the order of the cells can be accurately determined according to the ARFCN of the cells, and the j-th information field can be specifically the scheduling information of the j-th scheduled cell.

[0072] In one embodiment, the multiple scheduling information includes n scheduling information, and the multiple scheduled cells include the cell where the terminal is located when receiving the DCI and n-1 other cells; the predefined rule stipulates that the first scheduling information among the n scheduling information is associated with the cell where the terminal is located when receiving the DCI, and the information indicated by the i-th scheduling information among the second scheduling information to the n-th scheduling information is associated with the i-1-th other cell among the n-1 other cells, wherein 2≤i≤n.

[0073] The scheduled cells may include the cell in which the terminal receives the DCI and other cells (cells other than the cell in which the terminal receives the DCI among the scheduled cells), or may exclude the cell in which the terminal receives the DCI and only include other cells. In this implementation, the predefined rules may distinguish between the cell in which the terminal receives the DCI and other cells when specifying the association between the scheduled cells and the scheduling information, and specify the association between the cell in which the terminal receives the DCI and other cells and the scheduling information according to different rules.

[0074] Taking n scheduled cells as an example, if the n scheduled cells include the cell where the terminal is located when receiving the DCI and n-1 other cells. The n scheduling information can be determined based on the first association relationship and the value of the scheduling information in the DCI, and the correspondence between the n scheduling information and the n scheduled cells can be determined based on the second association relationship. The second association relationship can be that the first scheduling information in the n scheduling information is associated with the cell where the terminal is located when receiving the DCI, and the i-th scheduling information in the second to n-th scheduling information is associated with the i-1-th other cell in the n-1 other cells. That is, for the n-1 other cells, the association relationship between the cell and the scheduling information is specified according to the same rules, while for the cell where the terminal is located when receiving the DCI, it is specified to be associated with the first scheduling information.

[0075] Based on this, the terminal can determine that the first scheduling information is the scheduling information of the cell where the terminal is located when the terminal receives the DCI. From the second scheduling information to the nth scheduling information, the i-th scheduling information is the scheduling information of the i-1th other cell. Therefore, on the basis of the network device scheduling multiple cells through one DCI, the terminal can accurately interpret the scheduling information of each cell indicated by the DCI.

[0076] For example, for the n scheduled cells from the 1st cell to the nth scheduled cell, if the n scheduled cells include the cell where the terminal is located when receiving the DCI and n-1 other cells, taking the FDRA domain using the combine indication method as an example, n scheduling information can be determined based on the value of the FDRA domain and the first association relationship. The second association relationship specified by the predefined rule can be that the 1st FDRA domain in the n FDRA domains is associated with the cell where the terminal is located when receiving the DCI, and in the n-1 FDRA domains from the 2nd FDRA domain to the nth FDRA domain, the i-th information domain is associated with the i-1th other cell. If the cell id of the cell where the terminal is located when receiving the DCI is not in the range k1 to k n-1 Then the cell ID of the i-1th scheduled cell can be k i-1 .

[0077] In this embodiment, the terminal can determine, based on the second association relationship, that the first scheduling information is the frequency domain scheduling information of the cell where the terminal is located when the terminal receives the DCI, and in the n-1 scheduling information from the second scheduling information to the n-th scheduling information, the second scheduling information is the frequency domain scheduling information of the first other cell,..., the i-th scheduling information is the frequency domain scheduling information of the i-1-th other cell,..., the n-th scheduling information is the frequency domain scheduling information of the n-1-th other cell, so that on the basis of scheduling multiple cells through one DCI, the terminal can accurately interpret the frequency domain scheduling information of each cell indicated by the DCI.

[0078] For example, for the n scheduled cells from the 1st cell to the nth scheduled cell, taking the ZP CSI-RS trigger field using the combine indication method as an example, n scheduling information can be determined according to the value of the ZP CSI-RS trigger field and the first association relationship. The second association relationship specified by the predefined rule can be that the 1st ZP CSI-RS trigger field in the n ZP CSI-RS trigger field is associated with the cell where the terminal is located when receiving the DCI, and in the n-1 FDRA fields from the 2nd ZP CSI-RS trigger field to the nth ZP CSI-RS trigger field, the i-th information field is associated with the i-1th other cell. If the cell id of the cell where the terminal is located when receiving the DCI is not in the range k1 to k n-1 Then the cell ID of the i-1th scheduled cell can be k i-1 .

[0079] In this embodiment, the terminal can determine, based on the second association relationship, that the first scheduling information is the ZP CSI-RS trigger information of the cell where the terminal is located when receiving the DCI, and in the n-1 scheduling information from the second scheduling information to the n-th scheduling information, the second scheduling information is the ZP CSI-RS trigger information of the first other cell (cell k1), ..., the i-th scheduling information is the ZP CSI-RS trigger information of the i-1-th other cell (cell k i-1 ) ZP CSI-RS trigger information, ..., nth scheduling information for the n-1th other cell (cell k n-1 ), so that on the basis of scheduling multiple cells through one DCI, the terminal can accurately interpret the ZP CSI-RS trigger information of each cell indicated by the DCI.

[0080] For example, for the n scheduled cells from the 1st cell to the nth scheduled cell, if the n scheduled cells include the cell where the terminal is located when receiving the DCI and n-1 other cells, taking the BWP indication field using the combine indication method as an example, n scheduling information can be determined according to the value of the BWP indication field and the first association relationship. The second association relationship specified by the predefined rule can be that the 1st BWP indication field in the n BWP indication fields is associated with the cell where the terminal is located when receiving the DCI, and in the n-1 FDRA fields from the 2nd BWP indication field to the nth BWP indication field, the i-th information field is associated with the i-1th other cell. If the cell id of the cell where the terminal is located when receiving the DCI is not in the range k1 to k n-1 Then the cell ID of the i-1th scheduled cell can be k i-1 .

[0081] In this embodiment, the terminal can determine, according to the second association relationship, that the first scheduling information is the BWP information of the first cell, and in the n-1 scheduling information from the second scheduling information to the n-th scheduling information, the second scheduling information is the BWP information of the first other cell (cell k1), ..., the i-th scheduling information is the BWP information of the i-1-th other cell (cell k i-1 )'s BWP information, ..., the nth scheduling information is the n-1th other cell (cell k n-1 ), so that on the basis of scheduling multiple cells through one DCI, the terminal can accurately interpret the BWP information of each cell indicated by the DCI.

[0082] Regarding the order of multiple scheduled cells, how to determine it will be described in subsequent embodiments.

[0083] The following describes, through several embodiments, how to determine the order of multiple scheduled cells by predefined rules according to different rules specifying the association between the cell where the terminal receives the DCI and other cells and the information domain.

[0084] In one embodiment, the predefined rule stipulates that the identifier of the i-1th scheduled cell is smaller than the identifier of the i-th scheduled cell; or, the predefined rule stipulates that the identifier of the i-1th scheduled cell is larger than the identifier of the i-th scheduled cell.

[0085] Regarding the identifier of the scheduled cell (e.g., Cell ID), the terminal can determine it based on the RRC signaling sent by the network device, for example, based on IEs such as ServcellIndex and / or SCellIndex in the RRC signaling; and if the cell identifier corresponds to PCI, it can be determined based on the information element PhysCellId in the RRC signaling; of course, it can also be determined in other ways, for example, it can be specified by predefined rules.

[0086] The predefined rule may specify that the scheduled cells are sorted according to their identifiers. For example, the identifiers may be sorted from small to large. Then, the cell where the terminal is located when receiving the DCI is the first cell, and the identifier of the i-1th other cell is smaller than the identifier of the i-th other cell. If the cell ID of the cell where the terminal is located when receiving the DCI is not between k1 and k n-1 Between, k i-1 Less than k i ; Or sort by identifier from large to small, then the cell where the terminal receives the DCI is the first cell, the identifier of the i-1th other cell is greater than the identifier of the i-th other cell, if the cell id of the cell where the terminal receives the DCI is not in the range k1 to k n-1 Between, k i-1 Greater than k i .

[0087] For example, take 4 scheduled cells as an example, namely cell #1 with identification 1, cell #2 with identification 2, cell #3 with identification 3 and cell #4 with identification 4, where cell #3 is the cell where the terminal receives the DCI. If the identifiers are sorted from small to large, the first scheduled cell is cell #3. For other cells except cell #3, k i-1 Less than k i , the second scheduled cell is cell #1, the third scheduled cell is cell #2, and the fourth scheduled cell is cell #4; if sorted from large to small according to the identifier, the first scheduled cell is cell #3. For other cells except cell #3, k i-1 Greater than k i, the second scheduled cell is cell #4, the third scheduled cell is cell #2, and the fourth scheduled cell is cell #1.

[0088] Based on this, the order of the cells can be accurately determined according to the cell identifiers, and the first scheduling information can be determined to be the scheduling information of the cell where the terminal receives the DCI, and the i-th scheduling information is specifically the scheduling information of the i-th other cell.

[0089] In one embodiment, the predefined rule stipulates that the center frequency of the i-1th scheduled cell is less than the center frequency of the i-th scheduled cell; or, the predefined rule stipulates that the center frequency of the i-1th scheduled cell is less than the center frequency of the i-th scheduled cell.

[0090] Regarding the center frequency of the scheduled cell, the terminal can determine it based on the information sent by the network device, for example, based on the synchronization signal block SSB sent by the network device; of course, it can also be determined in other ways, for example, it can be specified by predefined rules.

[0091] The predefined rules may specify that the scheduled cells are sorted according to the center frequencies of the scheduled cells. For example, they may be sorted from small to large according to the center frequencies, so that the cell where the terminal is located when receiving the DCI is the first cell, and the center frequency of the i-1th other cell is less than the center frequency of the i-th other cell; or they may be sorted from large to small according to the center frequencies, so that the cell where the terminal is located when receiving the DCI is the first cell, and the center frequency of the i-1th other cell is greater than the center frequency of the i-th other cell.

[0092] For example, taking four scheduled cells, the center frequency of cell #1 is f1, the center frequency of cell #2 is f2, the center frequency of cell #3 is f3, and the center frequency of cell #4 is f4, where f1>f2>f3>f4. Cell #3 is the cell where the terminal receives the DCI. If sorted by center frequency from small to large, the first scheduled cell is cell #3, the second scheduled cell is cell #4, the third scheduled cell is cell #2, and the fourth scheduled cell is cell #1. If sorted by center frequency from large to small, the first scheduled cell is cell #3, the second scheduled cell is cell #1, the third scheduled cell is cell #2, and the fourth scheduled cell is cell #4.

[0093] Based on this, the order of the cells can be accurately determined according to the center frequency of the cells, and then the first scheduling information can be determined to be the scheduling information of the cell where the terminal receives the DCI, and the i-th scheduling information is specifically the scheduling information of the i-th other cell.

[0094] In one embodiment, the predefined rule stipulates that the absolute radio frequency channel number ARFCN corresponding to the center frequency of the i-1th scheduled cell is smaller than the ARFCN corresponding to the center frequency of the i-th scheduled cell; or, the predefined rule stipulates that the ARFCN corresponding to the center frequency of the i-1th scheduled cell is greater than the ARFCN corresponding to the center frequency of the i-th scheduled cell.

[0095] Regarding the ARFCN of the scheduled cell, the terminal may determine it according to the center frequency of the scheduled cell or by other means.

[0096] The predefined rules may specify that the scheduled cells are sorted according to the ARFCN of the scheduled cells. For example, they may be sorted from small to large according to ARFCN, so that the cell where the terminal is located when receiving the DCI is the first cell, and the ARFCN of the i-1th other cell is smaller than the ARFCN of the i-th other cell; or they may be sorted from large to small according to ARFCN, so that the cell where the terminal is located when receiving the DCI is the first cell, and the ARFCN of the i-1th other cell is larger than the ARFCN of the i-th other cell.

[0097] For example, taking four scheduled cells, the ARFCN of cell #1 is ARFCN#1, the ARFCN of cell #2 is ARFCN#2, the ARFCN of cell #3 is ARFCN#3, and the ARFCN of cell #4 is ARFCN#4, where ARFCN#1>ARFCN#2>ARFCN#3>ARFCN#4. Cell #3 is the cell where the terminal receives the DCI. If sorted by ARFCN from small to large, the first scheduled cell is cell #3, the second scheduled cell is cell #4, the third scheduled cell is cell #2, and the fourth scheduled cell is cell #1. If sorted by ARFCN from large to small, the first scheduled cell is cell #3, the second scheduled cell is cell #1, the third scheduled cell is cell #2, and the fourth scheduled cell is cell #4.

[0098] Based on this, the order of cells can be accurately determined according to their ARFCNs, and the first scheduling information can be determined to be the scheduling information of the cell where the terminal receives the DCI, and the i-th scheduling information is specifically the scheduling information of the i-th other cell.

[0099] Figure 2This is a schematic flow chart illustrating a method for transmitting downlink control information according to an embodiment of the present disclosure. The method for transmitting downlink control information illustrated in this embodiment can be applied to network devices that can communicate with terminals, including but not limited to base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations, and terminals including but not limited to mobile phones, tablet computers, wearable devices, sensors, and IoT devices.

[0100] like Figure 2 As shown, the method for sending downlink control information may include the following steps:

[0101] In step S201, a first association relationship between a value of a specific information field in the DCI and multiple scheduling information of the same type, and a second association relationship between the multiple scheduling information and multiple scheduled cells are determined;

[0102] In step S202, a DCI is generated according to the first association relationship and the second association relationship;

[0103] In step S203, the generated DCI is sent to the terminal.

[0104] In one embodiment, the DCI may include multiple types of information fields, such as an FDRA field, a ZP CSI-RStrigger field, a fractional bandwidth indication field, and the like.

[0105] For DCI of the existing mechanism, one type of information field can schedule a cell. For example, the FDRA information field can schedule the frequency domain resources of the target cell.

[0106] This embodiment can be applied in a scenario where a DCI schedules multiple cells. In this embodiment, the network device can send DCI to the terminal for scheduling multiple cells (i.e., scheduled cells). Specifically, the value of a specific information field in the DCI (the value of a certain information field, not the values ​​of multiple information fields) can be associated with multiple scheduling information (i.e., the value of one information field is associated with multiple scheduling information), for example, referred to as a first association relationship, and an association relationship can be established between multiple scheduling information and multiple scheduled cells, for example, referred to as a second association relationship. The multiple scheduling information types corresponding to the values ​​of one type of information field are the same, for example, corresponding to the frequency domain resources FDRA of different cells, for example, corresponding to the BWP indexes configured for different cells, as described below.

[0107] This indication method may be referred to as a combined or shared indication. For example, a specific value indicated by a specific type of information field in a DCI may be associated with multiple scheduling information, and the multiple scheduling information may be associated with multiple scheduled cells.

[0108] The first association relationship can be determined in a predefined manner or in a signaling indication manner. Taking the signaling indication method as an example, the network side can define the first association relationship between the specific value indicated by the DCI specific type information field and multiple scheduling information based on the signaling indication (such as radio resource control RRC signaling). The signaling can be the signaling configured by the cell where the DCI is received. Taking RRC signaling as an example, the terminal receives the corresponding RRC signaling in the cell where the DCI is received, and the RRC signaling indicates the association relationship between the specific value indicated by the DCI specific type information field and multiple scheduling information. Among them, the number of bits occupied by the specific type information field is related to the range of the indication value configured by the RRC signaling.

[0109] like Figure 1B As shown, taking the BWP indication field as an example, in a DCI used to schedule three cells (cell ID numbers are 0, 1 and 2 respectively), the corresponding DCI is received in cell 0.

[0110] For example, the first association is determined by signaling, and the terminal receives corresponding RRC signaling in cell 0 to determine a first association between the value of the BWP indication field in the DCI used to schedule multiple cells and the BWP IDs configured for multiple cells. For example, for the BWP indication field, the first association may be as shown in Table 1 above.

[0111] As shown in Table 1, the number of bits occupied by the BWP indication field is log2(4)=2. In the scenario where the value of the BWP indication field is 01, the value of the BWP indication field can be determined to be 01 according to the first association relationship. For example, the value 001 of the BWP indication field can be associated with 3 scheduling information, the first scheduling information is BWP id=2, the second scheduling information is BWP id=3, and the third scheduling information is BWPid=1. The first scheduling information is associated with cell 0, the second scheduling information is associated with cell 1, and the third scheduling information is associated with cell 2. Then, it can be determined that the BWP id of cell 0 is 2, the BWP id of cell 1 is 3, and the BWP id of cell 2 is 1.

[0112] For the information field of the characteristic type in the DCI that schedules multiple cells, the value of the information field can be associated with the scheduling information There are n scheduling information in total, where n is equal to the number of scheduled cells. is the scheduling information of cell k1, is cell k j Scheduling information, and so on. is cell k n Scheduling information, where k j The cell ID number.

[0113] The network device can determine a first association relationship between the value of a specific information field in the DCI and multiple scheduling information, and a second association relationship between multiple scheduling information and multiple scheduled cells, and then generate DCI based on the first association relationship and the second association relationship, and send the generated DCI to the terminal. After the terminal receives the DCI sent by the network device, it can determine the multiple scheduling information corresponding to the value of the specific information field in the DCI based on the first association relationship, and determine the scheduled cell corresponding to each scheduling information based on the second association relationship, and then determine the scheduling information of each scheduled cell. Therefore, on the basis of scheduling multiple cells through one DCI, the terminal can accurately interpret the scheduling information of each cell indicated by the DCI. The above mainly introduces the specific implementation method of the first association relationship, and the determination relationship corresponding to the second association relationship will be expanded below.

[0114] It should be noted that regarding the multiple cells scheduled by DCI, that is, the multiple scheduled cells, the network equipment can indicate and determine the terminal based on the CIF in the DCI, or it can be pre-agreed with the terminal, or it can be determined according to predefined rules (such as protocol agreements), and this disclosure does not limit it.

[0115] In one embodiment, determining a first association between a value of a specific information field in the DCI and multiple pieces of scheduling information of the same type includes: determining the first association and / or the second association based on an implementation of the network device; wherein the method further includes indicating the first association to the terminal. For example, the network device may determine the association between the value of the specific information field in the DCI and the multiple pieces of scheduling information, and then indicate it to the terminal via RRC signaling. Of course, the association may also be determined based on predefined rules, such as based on protocol agreements.

[0116] In one embodiment, determining the second association relationship between the plurality of scheduling information and the plurality of scheduled cells includes: determining the second association relationship according to a predefined rule.

[0117] The first association relationship between the value of a specific information field in the DCI and multiple scheduling information, and the second association relationship between the multiple scheduling information and multiple scheduled cells, may be specified by a predefined rule, such as a protocol agreement; or may be indicated by a network device, wherein the manner in which the network device indicates the association relationship includes but is not limited to indication through RRC signaling, indication through DCI, and indication through MAC CE. The number of bits occupied by the information field in the DCI is determined by the number of values ​​determined based on the signaling indication or in a predetermined manner. For example, if the first association relationship defines the values ​​of N information fields, and the value of each information field is associated with multiple scheduling information, then the number of bits occupied by the information field in the DCI is equal to log2(N).

[0118] The following embodiments are mainly used to exemplify the case where the second association relationship is specified by a predefined rule.

[0119] In one embodiment, the multiple scheduling information includes n scheduling information, and the multiple scheduled cells include n scheduled cells; the predefined rule stipulates that the jth scheduling information among the n scheduling information is associated with the jth scheduled cell among the n scheduled cells, where 1≤j≤n.

[0120] The scheduled cells may include the cell in which the terminal receives the DCI and other cells (cells other than the cell in which the terminal receives the DCI among the scheduled cells), or may exclude the cell in which the terminal receives the DCI and only include other cells. In this implementation, the predefined rules may not distinguish between the cell in which the terminal receives the DCI and other cells when specifying the association between the scheduled cells and the scheduling information, and the association between the cell in which the terminal receives the DCI and other cells and the scheduling information may be specified according to the same rules.

[0121] Taking n scheduled cells as an example, the network device can determine a first association between the value of the information field in the DCI and the n scheduling information, and indicate the first association to the terminal. A corresponding relationship between the n scheduling information and the n scheduled cells can also be determined based on a second association. The second association can be that the jth scheduling information in the n scheduling information is associated with the jth scheduled cell in the n scheduled cells. Furthermore, based on the first and second associations, a DCI can be generated to schedule multiple cells using one DCI.

[0122] Accordingly, the network device can indicate n pieces of scheduling information associated with n scheduled information through the value of the information field in the DCI. The terminal can determine that the jth piece of scheduling information is the scheduling information of the jth scheduled cell. Thus, based on the network device scheduling multiple cells through a single DCI, the terminal can accurately interpret the scheduling information of each cell indicated by the DCI.

[0123] For example, for the n scheduled cells from the first cell to the nth scheduled cell, taking the FDRA field using the combine indication mode as an example, the network device can determine the value of the FDRA field and the n scheduling information (for example to where k j In this embodiment, the network device can determine, based on the second association relationship, that the first scheduling information is the frequency domain scheduling information of the first scheduled cell (cell k1), the second scheduling information is the frequency domain scheduling information of the second scheduled cell (cell k2), ..., the jth scheduling information is the frequency domain scheduling information of the jth scheduled cell (cell k j ) frequency domain scheduling information, ..., nth scheduling information is the frequency domain scheduling information of the nth scheduled cell (cell k n ), and then generate DCI according to the first association relationship and the second association relationship, so as to schedule multiple cells through one DCI, and enable the terminal to accurately interpret the frequency domain scheduling information of each cell indicated by the DCI.

[0124] For example, for the n scheduled cells from the first cell to the nth scheduled cell, taking the ZP CSI-RS trigger field using the combine indication method as an example, the network device can determine the value of the ZP CSI-RS trigger field and the n scheduling information (for example to where k j In this embodiment, the network device can determine, based on the second association relationship, that the first scheduling information is the ZP CSI-RS trigger information of the first scheduled cell (cell k1), the second scheduling information is the ZP CSI-RS trigger information of the second scheduled cell (cell k2), ..., the jth scheduling information is the ZP CSI-RS trigger information of the jth scheduled cell (cell k j ) ZP CSI-RS trigger information, ..., nth scheduling information for the nth scheduled cell (cell k n), and then generate DCI according to the first association relationship and the second association relationship, so as to schedule multiple cells through one DCI, and enable the terminal to accurately interpret the ZP CSI-RS trigger information of each cell indicated by the DCI.

[0125] For example, for the n scheduled cells from the first cell to the nth scheduled cell, taking the BWP indication field adopting the combine indication mode as an example, the network device can determine the value of the BWP indication field and the n scheduling information (for example to where k j In this embodiment, the network device can determine, based on the second association relationship, that the first scheduling information is the BWP information of the first scheduled cell (cell k1), the second scheduling information is the BWP information of the second scheduled cell (cell k2), ..., the jth scheduling information is the BWP information of the jth scheduled cell (cell k j ) BWP information, ..., nth BWP scheduling information (cell k n ) is the BWP information of the nth scheduled cell, and then a DCI can be generated according to the first association relationship and the second association relationship, so that multiple cells can be scheduled through one DCI, and the terminal can accurately interpret the BWP information of each cell indicated by the DCI.

[0126] The order of the multiple scheduled cells will be determined in the subsequent embodiments.

[0127] The following describes, through several embodiments, how to determine the order of multiple scheduled cells by predefined rules that specify the association between the cell where the terminal receives the DCI and other cells and the information domain according to the same rule.

[0128] In one embodiment, the predefined rule stipulates that the identifier of the jth scheduled cell is smaller than the identifier of the j+1th scheduled cell, for example, j Less than k j+1 Or, the predefined rule stipulates that the identifier of the jth scheduled cell is greater than the identifier of the j+1th scheduled cell, for example, k j Greater than k j+1 .

[0129] In one implementation, the network device may indicate the identifier of the scheduled cell (e.g., Cell ID) to the terminal, for example, through RRC signaling, such as through information elements such as ServcellIndex and / or SCellIndex in the RRC signaling. If the cell identifier corresponds to the PCI, then it may be indicated through the information element PhysCellId in the RRC signaling. Of course, the terminal may also determine it based on other signaling or other methods, such as those specified by predefined rules.

[0130] The predefined rules may specify that the scheduled cells are sorted according to their identifiers. For example, they may be sorted from small to large according to their identifiers, so that the identifier of the jth scheduled cell is smaller than the identifier of the j+1th scheduled cell, or they may be sorted from large to small according to their identifiers, so that the identifier of the jth scheduled cell is larger than the identifier of the j+1th scheduled cell.

[0131] For example, take 4 scheduled cells as an example, which are cell #1 with ID 1, cell #2 with ID 2, cell #3 with ID 3 and cell #4 with ID 4. If they are sorted from small to large according to ID, then k j Less than k j+1 , we can determine that the first cell is cell #1, the second scheduled cell is cell #2, the third cell is cell #3, and the fourth cell is cell #4; if we sort them from large to small according to the identifier, then k j Greater than k j+1 , it can be determined that the first cell is cell #4, the second scheduled cell is cell #3, the third cell is cell #2, and the fourth cell is cell #1.

[0132] Based on this, the order of the cells can be accurately determined according to the cell identifiers, and further, it can be determined that the j-th information field is specifically the scheduling information of the j-th scheduled cell.

[0133] In one embodiment, the predefined rule stipulates that the center frequency of the jth scheduled cell is less than the center frequency of the j+1th scheduled cell; or, the predefined rule stipulates that the center frequency of the jth scheduled cell is greater than the center frequency of the j+1th scheduled cell.

[0134] Regarding the center frequency of the scheduled cell, the network device can send information to instruct the terminal, such as sending a synchronization signal block SSB (Synchronization Signal Block) for instruction; of course, the terminal can also determine it according to other methods, such as it can be specified by predefined rules.

[0135] The predefined rules may specify that the scheduled cells are sorted according to their center frequencies. For example, they may be sorted from small to large according to their center frequencies, so that the center frequency of the jth scheduled cell is less than the center frequency of the j+1th scheduled cell, or they may be sorted from large to small according to their center frequencies, so that the center frequency of the jth scheduled cell is greater than the center frequency of the j+1th scheduled cell.

[0136] For example, take four scheduled cells: cell #1 has a center frequency of f1, cell #2 has a center frequency of f2, cell #3 has a center frequency of f3, and cell #4 has a center frequency of f4, where f1 > f2 > f3 > f4. If the cells are sorted by center frequency in ascending order, the first cell is cell #4, the second scheduled cell is cell #3, the third cell is cell #2, and the fourth cell is cell #1. If the cells are sorted by center frequency in descending order, the first cell is cell #1, the second scheduled cell is cell #2, the third cell is cell #3, and the fourth cell is cell #4.

[0137] Accordingly, the order of the cells can be accurately determined according to the center frequencies of the cells, and the j-th information field can be specifically the scheduling information of the j-th scheduled cell.

[0138] In one embodiment, the predefined rule stipulates that the absolute radio frequency channel number ARFCN corresponding to the center frequency of the j-th scheduled cell is less than the ARFCN corresponding to the center frequency of the j+1-th scheduled cell; or, the predefined rule stipulates that the ARFCN corresponding to the center frequency of the j-th scheduled cell is greater than the ARFCN corresponding to the center frequency of the j+1-th scheduled cell.

[0139] The ARFCN of the scheduled cell may be determined according to the center frequency of the scheduled cell or by other means.

[0140] The predefined rules may specify that the scheduled cells are sorted according to the ARFCN of the scheduled cells. For example, they may be sorted from small to large according to ARFCN, so that the ARFCN of the j-th scheduled cell is smaller than the ARFCN of the j+1-th scheduled cell, or they may be sorted from large to small according to ARFCN, so that the ARFCN of the j-th scheduled cell is larger than the ARFCN of the j+1-th scheduled cell.

[0141] For example, taking four scheduled cells, the ARFCN of cell #1 is ARFCN#1, the ARFCN of cell #2 is ARFCN#2, the ARFCN of cell #3 is ARFCN#3, and the ARFCN of cell #4 is ARFCN#4. Here, ARFCN#1 > ARFCN#2 > ARFCN#3 > ARFCN#4. If sorted by ARFCN from smallest to largest, the first cell is cell #4, the second scheduled cell is cell #3, the third cell is cell #2, and the fourth cell is cell #1. If sorted by ARFCN from largest to smallest, the first cell is cell #1, the second scheduled cell is cell #2, the third cell is cell #3, and the fourth cell is cell #4.

[0142] Accordingly, the order of the cells can be accurately determined according to the ARFCN of the cells, and the j-th information field can be specifically the scheduling information of the j-th scheduled cell.

[0143] In one embodiment, the multiple scheduling information includes n scheduling information, and the multiple scheduled cells include the cell where the terminal is located when receiving the DCI and n-1 other cells; the predefined rule stipulates that the first scheduling information among the n scheduling information is associated with the cell where the terminal is located when receiving the DCI, and the information indicated by the i-th scheduling information among the second scheduling information to the n-th scheduling information is associated with the i-1-th other cell among the n-1 other cells, wherein 2≤i≤n.

[0144] The scheduled cells may include the cell in which the terminal receives the DCI and other cells (cells other than the cell in which the terminal receives the DCI among the scheduled cells), or may exclude the cell in which the terminal receives the DCI and only include other cells. In this implementation, the predefined rules may distinguish between the cell in which the terminal receives the DCI and other cells when specifying the association between the scheduled cells and the scheduling information, and specify the association between the cell in which the terminal receives the DCI and other cells and the scheduling information according to different rules.

[0145] Taking n scheduled cells as an example, the network device can determine the first association relationship between the value of the information field in the DCI and the n scheduling information, and indicate the first association relationship to the terminal. The correspondence between the n scheduling information and the n scheduled cells can also be determined based on the second association relationship. The second association relationship can be that the first scheduling information among the n scheduling information is associated with the cell where the terminal is located when receiving the DCI, and the i-th scheduling information among the second scheduling information to the n-th scheduling information is associated with the i-1-th other cell among the n-1 other cells. That is, for the n-1 other cells, the association relationship between the cell and the scheduling information is specified according to the same rules, while for the cell where the terminal is located when receiving the DCI, it is specified to be associated with the first scheduling information.

[0146] Accordingly, the network device can indicate n pieces of scheduling information associated with n scheduled information through the value of the information field in the DCI. The terminal can determine that the first piece of scheduling information is the scheduling information of the cell in which the terminal receives the DCI, and from the second scheduling information to the nth scheduling information, the i-th scheduling information is the scheduling information of the i-1th other cell. Therefore, based on the network device scheduling multiple cells through one DCI, the terminal can accurately interpret the scheduling information of each cell indicated by the DCI.

[0147] For example, for the n scheduled cells from the 1st cell to the nth scheduled cell, if the n scheduled cells include the cell where the terminal is located when receiving the DCI and n-1 other cells, taking the FDRA domain using the combine indication method as an example, n scheduling information can be determined based on the value of the FDRA domain and the first association relationship. The second association relationship specified by the predefined rule can be that the 1st FDRA domain in the n FDRA domains is associated with the cell where the terminal is located when receiving the DCI, and in the n-1 FDRA domains from the 2nd FDRA domain to the nth FDRA domain, the i-th information domain is associated with the i-1th other cell. If the cell id of the cell where the terminal is located when receiving the DCI is not in the range k1 to k n-1 Then the cell ID of the i-1th scheduled cell can be k i-1 .

[0148] In this embodiment, the network device can determine, based on the second association relationship, that the first scheduling information is the frequency domain scheduling information of the cell where the terminal is located when the terminal receives the DCI, and in the n-1 scheduling information from the second scheduling information to the n-th scheduling information, the second scheduling information is the frequency domain scheduling information of the first other cell,..., the i-th scheduling information is the frequency domain scheduling information of the i-1-th other cell,..., the n-th scheduling information is the frequency domain scheduling information of the n-1-th other cell, and then DCI can be generated based on the first association relationship and the second association relationship, so as to realize scheduling of multiple cells through one DCI, and enable the terminal to accurately interpret the frequency domain scheduling information of each cell indicated by the DCI.

[0149] For example, for the n scheduled cells from the 1st cell to the nth scheduled cell, taking the ZP CSI-RS trigger field using the combine indication method as an example, n scheduling information can be determined according to the value of the ZP CSI-RS trigger field and the first association relationship. The second association relationship specified by the predefined rule can be that the 1st ZP CSI-RS trigger field in the n ZP CSI-RS trigger field is associated with the cell where the terminal is located when receiving the DCI, and in the n-1 FDRA fields from the 2nd ZP CSI-RS trigger field to the nth ZP CSI-RS trigger field, the i-th information field is associated with the i-1th other cell. If the cell id of the cell where the terminal is located when receiving the DCI is not in the range k1 to k n-1 Then the cell ID of the i-1th scheduled cell can be k i-1 .

[0150] In this embodiment, the network device can determine, based on the second association relationship, that the first scheduling information is the ZP CSI-RS trigger information of the cell where the terminal receives the DCI, and in the n-1 scheduling information from the second scheduling information to the n-th scheduling information, the second scheduling information is the ZP CSI-RS trigger information of the first other cell (cell k1), ..., the i-th scheduling information is the ZP CSI-RS trigger information of the i-1-th other cell (cell k i-1 ) ZP CSI-RS trigger information, ..., nth scheduling information for the n-1th other cell (cell k n-1 ), and then generate DCI according to the first association relationship and the second association relationship, so as to schedule multiple cells through one DCI, and enable the terminal to accurately interpret the ZP CSI-RS trigger information of each cell indicated by the DCI.

[0151] For example, for the n scheduled cells from the 1st cell to the nth scheduled cell, if the n scheduled cells include the cell where the terminal is located when receiving the DCI and n-1 other cells, taking the BWP indication field using the combine indication method as an example, n scheduling information can be determined according to the value of the BWP indication field and the first association relationship. The second association relationship specified by the predefined rule can be that the 1st BWP indication field in the n BWP indication fields is associated with the cell where the terminal is located when receiving the DCI, and in the n-1 FDRA fields from the 2nd BWP indication field to the nth BWP indication field, the i-th information field is associated with the i-1th other cell. If the cell id of the cell where the terminal is located when receiving the DCI is not in the range k1 to k n-1 Then the cell ID of the i-1th scheduled cell can be k i-1 .

[0152] In this embodiment, the network device can determine, according to the second association relationship, that the first scheduling information is the BWP information of the first cell, and in the n-1 scheduling information from the second scheduling information to the n-th scheduling information, the second scheduling information is the BWP information of the first other cell (cell k1), ..., the i-th scheduling information is the BWP information of the i-1-th other cell (cell k i-1 )'s BWP information, ..., the nth scheduling information is the n-1th other cell (cell k n-1 ), and then generate DCI according to the first association relationship and the second association relationship, so as to schedule multiple cells through one DCI, and enable the terminal to accurately interpret the BWP information of each cell indicated by the DCI.

[0153] Regarding the order of multiple scheduled cells, how to determine it will be described in subsequent embodiments.

[0154] The following describes, through several embodiments, how to determine the order of multiple scheduled cells by predefined rules according to different rules specifying the association between the cell where the terminal receives the DCI and other cells and the information domain.

[0155] In one embodiment, the predefined rule stipulates that the identifier of the i-1th scheduled cell is smaller than the identifier of the i-th scheduled cell; or, the predefined rule stipulates that the identifier of the i-1th scheduled cell is larger than the identifier of the i-th scheduled cell.

[0156] In one embodiment, the network device may indicate to the terminal the identifier of the scheduled cell (e.g., Cell ID), for example, through RRC signaling, for example, through information elements (IE) such as ServcellIndex and / or SCellIndex in the RRC signaling; and if the cell identifier corresponds to PCI (Physical CellIdentity), then it may be indicated through the information element PhysCellId in the RRC signaling; of course, the terminal may also determine it in other ways, for example, it may be specified by a predefined rule.

[0157] The predefined rule may specify that the scheduled cells are sorted according to their identifiers. For example, the identifiers may be sorted from small to large. Then, the cell where the terminal is located when receiving the DCI is the first cell, and the identifier of the i-1th other cell is smaller than the identifier of the i-th other cell. If the cell ID of the cell where the terminal is located when receiving the DCI is not between k1 and k n-1 Between, k i-1 Less than k i ; Or sort by identifier from large to small, then the cell where the terminal receives the DCI is the first cell, the identifier of the i-1th other cell is greater than the identifier of the i-th other cell, if the cell id of the cell where the terminal receives the DCI is not in the range k1 to k n-1 Between, k i-1 Greater than k i .

[0158] For example, take 4 scheduled cells as an example, namely cell #1 with identification 1, cell #2 with identification 2, cell #3 with identification 3 and cell #4 with identification 4, where cell #3 is the cell where the terminal receives the DCI. If the identifiers are sorted from small to large, the first scheduled cell is cell #3. For other cells except cell #3, k i-1 Less than k i , the second scheduled cell is cell #1, the third scheduled cell is cell #2, and the fourth scheduled cell is cell #4; if sorted from large to small according to the identifier, the first scheduled cell is cell #3. For other cells except cell #3, k i-1 Greater than k i , the second scheduled cell is cell #4, the third scheduled cell is cell #2, and the fourth scheduled cell is cell #1.

[0159] Based on this, the order of the cells can be accurately determined according to the cell identifiers, and the first scheduling information can be determined to be the scheduling information of the cell where the terminal receives the DCI, and the i-th scheduling information is specifically the scheduling information of the i-th other cell.

[0160] In one embodiment, the predefined rule stipulates that the center frequency of the i-1th scheduled cell is less than the center frequency of the i-th scheduled cell; or, the predefined rule stipulates that the center frequency of the i-1th scheduled cell is less than the center frequency of the i-th scheduled cell.

[0161] Regarding the center frequency of the scheduled cell, the network device can send information to instruct the terminal, such as sending a synchronization signal block SSB for instruction; of course, the terminal can also determine it according to other methods, such as it can be specified by predefined rules.

[0162] The predefined rules may specify that the scheduled cells are sorted according to the center frequencies of the scheduled cells. For example, they may be sorted from small to large according to the center frequencies, so that the cell where the terminal is located when receiving the DCI is the first cell, and the center frequency of the i-1th other cell is less than the center frequency of the i-th other cell; or they may be sorted from large to small according to the center frequencies, so that the cell where the terminal is located when receiving the DCI is the first cell, and the center frequency of the i-1th other cell is greater than the center frequency of the i-th other cell.

[0163] For example, taking four scheduled cells, the center frequency of cell #1 is f1, the center frequency of cell #2 is f2, the center frequency of cell #3 is f3, and the center frequency of cell #4 is f4, where f1>f2>f3>f4. Cell #3 is the cell where the terminal receives the DCI. If sorted by center frequency from small to large, the first scheduled cell is cell #3, the second scheduled cell is cell #4, the third scheduled cell is cell #2, and the fourth scheduled cell is cell #1. If sorted by center frequency from large to small, the first scheduled cell is cell #3, the second scheduled cell is cell #1, the third scheduled cell is cell #2, and the fourth scheduled cell is cell #4.

[0164] Based on this, the order of the cells can be accurately determined according to the center frequency of the cells, and then the first scheduling information can be determined to be the scheduling information of the cell where the terminal receives the DCI, and the i-th scheduling information is specifically the scheduling information of the i-th other cell.

[0165] In one embodiment, the predefined rule stipulates that the absolute radio frequency channel number ARFCN corresponding to the center frequency of the i-1th scheduled cell is smaller than the ARFCN corresponding to the center frequency of the i-th scheduled cell; or, the predefined rule stipulates that the ARFCN corresponding to the center frequency of the i-1th scheduled cell is greater than the ARFCN corresponding to the center frequency of the i-th scheduled cell.

[0166] The ARFCN of the scheduled cell may be determined according to the center frequency of the scheduled cell or by other means.

[0167] The predefined rules may specify that the scheduled cells are sorted according to the ARFCN of the scheduled cells. For example, they may be sorted from small to large according to ARFCN, so that the cell where the terminal is located when receiving the DCI is the first cell, and the ARFCN of the i-1th other cell is smaller than the ARFCN of the i-th other cell; or they may be sorted from large to small according to ARFCN, so that the cell where the terminal is located when receiving the DCI is the first cell, and the ARFCN of the i-1th other cell is larger than the ARFCN of the i-th other cell.

[0168] For example, taking four scheduled cells, the ARFCN of cell #1 is ARFCN#1, the ARFCN of cell #2 is ARFCN#2, the ARFCN of cell #3 is ARFCN#3, and the ARFCN of cell #4 is ARFCN#4, where ARFCN#1>ARFCN#2>ARFCN#3>ARFCN#4. Cell #3 is the cell where the terminal receives the DCI. If sorted by ARFCN from small to large, the first scheduled cell is cell #3, the second scheduled cell is cell #4, the third scheduled cell is cell #2, and the fourth scheduled cell is cell #1. If sorted by ARFCN from large to small, the first scheduled cell is cell #3, the second scheduled cell is cell #1, the third scheduled cell is cell #2, and the fourth scheduled cell is cell #4.

[0169] Based on this, the order of cells can be accurately determined according to their ARFCNs, and the first scheduling information can be determined to be the scheduling information of the cell where the terminal receives the DCI, and the i-th scheduling information is specifically the scheduling information of the i-th other cell.
