Fig. 1A is a schematic flow chart diagram illustrating a scheduling information determination method according to an embodiment of the present disclosure. The scheduling information determining method shown in this embodiment may be applied to 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. 1A, the scheduling information determining method may include the steps of:

in step S101, receiving downlink Control information dci (downlink Control information) for scheduling a plurality of cells sent by a network device;

in step S102, determining association relationships between a plurality of information fields of the same type in the DCI and a plurality of scheduled cells;

in step S103, according to the value of each information field and the association relationship, scheduling information of each scheduled cell is determined.

In one embodiment, a plurality of types of Information fields may be included in the DCI, such as an FDRA (Frequency Domain Resource Assignment) field, a ZP CSI-RS trigger (Zero Power Channel Information Reference Signal trigger) field, a partial BandWidth indicator (BandWidth Part indicator) field, and the like.

For DCI of an existing mechanism, generally, only one information field of the same type is included, and a cell may be scheduled according to the information field of the type, for example, the FDRA information field may schedule frequency domain resources of a target cell.

The embodiment can be applied to a scenario in which one DCI schedules a plurality of cells. In this embodiment, the network device may send DCI to the terminal for scheduling multiple cells (that is, scheduled cells), where one possible design manner is as follows: for one or more types of information fields in the DCI, multiple information fields of the same type may be set in the DCI for multiple scheduled cells, and each information field may be scheduled for one of the cells. The information fields of the same type are correspondingly indicated with the same information type, for example, frequency domain resources FDRA indicating different cells, for example, BWP indexes indicating different cell configurations, as described in detail below.

Such an indication manner may be referred to as a separate manner, for example, a specific type information field in one DCI may include a plurality of information fields. On the basis of scheduling information domains in one DCI of a single cell, corresponding bit expansion is carried out on the information domains of specific types according to the number of the cells to be scheduled, so that a plurality of information domains of the same type are obtained, wherein different information domains indicate messages of different cells. The number of bits occupied by a plurality of information domains of the same type in one DCI is equal to the sum of the number of bits occupied by the information domains corresponding to each dispatched cell. The number of bits occupied by the information domain corresponding to each scheduled cell is the same as the number of bits occupied by the same type of information domain of DCI scheduled for one cell in the existing mechanism.

Fig. 1B is a schematic view of an application scenario of a scheduling information determining method according to an embodiment of the present disclosure. As shown in fig. 1B, taking the BWP indication fields as an example, one DCI for scheduling 3 cells (

cell id numbers

0, 1, and 2, respectively) includes 3 BWP indication fields (BWP indication field #1, BWP indication field #2, BWP indication field #3), and the 3 BWP indication fields occupy 5bits, for example, a value of 01100.

Wherein, the 1 st and 2 nd bits (01) may correspond to cell 0 as BWP indication field #1, and then BWP id of cell 0 may be determined to be 2 according to the 1 st and 2 nd bits (01); the 3 rd and 4 th bits (10) may indicate that the field #2 corresponds to the cell 1 as BWP, and then the BWP id of the cell 1 may be determined to be 3 according to the 3 rd and 4 th bits (10); the 5 th bit (0) may indicate that the field #3 corresponds to the cell 0 as BWP, and then the BWP id of the cell 2 may be determined to be 1 according to the 5 th bit (0).

The number of bits occupied by the 3 BWP indication domains is equal to the sum of the number of bits occupied by the 3 BWP domains of the scheduled cell. The number of bits occupied by the BWP domain corresponding to a particular scheduled cell is determined based on existing mechanisms, i.e. based on the number n of higher layer configured BWPs for the particular scheduled cell _BWP,RRC And determining the number of bits occupied by the BWP domain corresponding to the specific scheduled cell.

For the specific type of information field in the DCI for scheduling multiple cells, if the specific type of information field adopts a separate mode, the specific type of information field may include multiple information fields, and the corresponding indexes of the multiple information field occupied bits are:

wherein, index 1 corresponds to the first bit in the DCI specific type information domain, and index

Corresponding bits for the 1 st information field for indicating the cell k ₀ Scheduling information, index of

Corresponding bits for j information domain to indicate the scheduling information of the cell, index

Corresponding bits for nth information field for indicating cell k _n N equals the number of cells scheduled, where k _j Is the cell id number. For example, the predefined rule may specify that a jth information field of the n information fields is associated with a jth scheduled cell of the n scheduled cells, wherein a cell id of the jth scheduled cell may be k _j 。

The terminal can determine the incidence relation between a plurality of information domains of the same type and a plurality of scheduled cells, and further determine the scheduled cell corresponding to each information domain according to the incidence relation, so that the scheduling information of the scheduled cell can be determined according to the value of the information domain corresponding to the scheduled cell. Therefore, the scheduling information of each cell is accurately determined on the basis of scheduling a plurality of cells through one DCI.

Since multiple types of information fields may be set in the DCI, for any one or several types of information fields, multiple information fields may be set in a separate manner to implement scheduling for multiple cells, and specifically, what type or types of information fields are set may be determined according to a predefined rule or according to a signaling instruction. For example, for the FDRA field and the BWP indication field, the signaling indicates that the FDRA field is indicated based on the separate manner, and then multiple FDRA fields may be set in DCI for multiple scheduled cells; for example, the predefined rule specifies a separate-based manner indication for both FDAR and BWP domains, then multiple FDRA domains and multiple BWP indication domains may be set in DCI for multiple scheduled cells.

It should be noted that, regarding the number of the multiple cells scheduled by the DCI and/or the Cell numbers corresponding to the multiple cells, that is, the multiple scheduled cells, the terminal may be determined according to a Cell Indicator Field (CIF) in the DCI, may also be agreed with the network device in advance, and may also be determined according to a predefined rule (for example, agreed with a protocol), which is not limited in this disclosure.

In one embodiment, the determining the association relationship between the plurality of information fields of the same type in the DCI and the plurality of scheduled cells comprises: and determining the association relation according to a predefined rule.

In one embodiment, the determining the association relationship between the plurality of information fields of the same type in the DCI and the plurality of scheduled cells comprises: and determining the association relation according to the indication of the network equipment.

The association relationship between a plurality of information fields of the same type in the DCI and a plurality of scheduled cells may be specified by a predefined rule, for example, agreed by a protocol; the association relationship may also be indicated by a network device, where the manner of indicating the association relationship by the network device includes, but is not limited to, indicating through a Radio Resource Control (RRC) signaling, indicating through a DCI, and indicating through a Media Access Control (MAC CE) Element.

The following embodiments mainly exemplify the case where the association relationship is specified by a predefined rule.

In one embodiment, the plurality of information fields includes n information fields, and the plurality of scheduled cells includes n scheduled cells; the predefined rule specifies that a jth information field of the n information fields is associated with a jth scheduled cell of the n scheduled cells, wherein j is greater than or equal to 1 and less than or equal to n.

The scheduled cell may include a cell in which the terminal receives the DCI and other cells (cells other than the cell in which the terminal receives the DCI in the scheduled cell), or may include only other cells, excluding the cell in which the terminal receives the DCI. In this embodiment, the predefined rule may specify the association between the information field and the cell in which the terminal receives the DCI without distinguishing between the cell and the other cells in which the terminal receives the DCI.

Taking n scheduled cells as an example, for a certain type of information domain, n information domains may be set to schedule the n scheduled cells, and the association relationship may be that the jth information domain in the n information domains is associated with the jth scheduled cell in the n scheduled cells.

Accordingly, the terminal can determine the scheduling information indicated by the value of the jth information field as the scheduling information of the jth scheduled cell, thereby accurately determining the scheduling information of each cell on the basis of scheduling a plurality of cells through one DCI. The number of bits occupied by the jth information domain and the specific indication mode are the same as the mode of scheduling a single cell by using a single DCI.

For example, for n scheduled cells from 1 st cell to nth scheduled cell, taking the FDRA field using the separate indication manner as an example, n FDRA fields may be set in DCI, and the predefined rule may specify that the jth information field of the n information fields is associated with the jth scheduled cell of the n scheduled cells, where the cell id of the jth scheduled cell may be k _j . In this embodiment, the terminal may determine that the 1 st FDRA domain indicates the 1 st scheduled cell (cell k) ₁ ) The 2 nd FDRA domain indicates the 2 nd scheduled cell (cell k) ₂ ) …, the jth FDRA field indicates the jth scheduled cell (cell k) _j ) …, the nth FDRA field indicates the nth scheduled cell (cell k) _n ) The frequency domain scheduling information of the cell indicated by the DCI can be accurately interpreted by the terminal on the basis of scheduling a plurality of cells by using one DCI.

The bits occupied by the jth FDRA domain is determined according to a mechanism in a communication protocol 38.212[2], that is: and determining the bits occupied by the jth FDRA domain and the corresponding relation between the value indicated by the FDRA domain and the frequency domain resource based on the resource allocation type ('type 0', 'type 1', 'dynamic') indicated by the high-level configuration signaling of the jth scheduled cell.

For example, for n scheduled cells from 1 st cell to nth scheduled cell, taking the ZP CSI-RS trigger field as an example of using the method of default indication, n ZP CSI-RS trigger fields may be set in DCI, and the predefined rule may specify that the jth information field of the n information fields is associated with the jth scheduled cell of the n scheduled cells, where the cell id of the jth scheduled cell may be k _j . In this embodiment, the terminal may determine that the 1 st ZP CSI-RS trigger field indicates the 1 st scheduled cell (cell k) ₁ ) The ZP CSI-RS trigger information and the 2 nd ZP CSI-RS trigger domain indicate the 2 nd scheduled cell (cell k) ₂ ) The ZP CSI-RS trigger information, … and the jth ZP CSI-RS trigger domain indicate the jth scheduled cell (cell k) _j ) The ZP CSI-RS trigger information, … and the nth ZP CSI-RS trigger domain indicate the nth scheduled cell (cell k) _n ) The ZP CSI-RS trigger information enables the terminal to accurately interpret the ZP CSI-RS trigger information of each cell indicated by the DCI on the basis of scheduling a plurality of cells through one DCI.

The bits number occupied by the jth ZP CSI-RS trigger domain is determined according to a mechanism in a communication protocol 38.212[2], namely: and determining the number of bits occupied by the jth ZP CSI-RS trigger domain based on the number nZP of the high-level configuration ZP CSI-RS resource sets of the jth scheduled cell.

For example, for n scheduled cells from the 1 st cell to the nth scheduled cell, taking the BWP indication field as an example in a separate indication manner, n BWP indication fields may be set in DCI, and the predefined rule may specify the first of the n information fieldsj information fields are associated with the jth scheduled cell of the n scheduled cells, wherein the cell id of the jth scheduled cell may be k _j . In this embodiment, the terminal may determine that the 1 st BWP indication field indicates the 1 st scheduled cell (cell k) ₁ ) The 2 nd BWP indication field indicates the 2 nd scheduled cell (cell k) ₂ ) The j-th BWP indication field indicates the j-th scheduled cell (cell k) of the BWP information of (…) _j ) The nth BWP indication field indicates the nth scheduled cell (cell k), … _n ) Thereby enabling the terminal to accurately interpret the BWP information of each cell indicated by the DCI on the basis of scheduling a plurality of cells by one DCI.

The number of bits occupied by the jth BWP domain is determined according to a mechanism in the communication protocol 38.212[2], that is: and based on the high-layer configuration BWP number nBWP of the jth scheduled cell, the RRC determines the number of bits occupied by the jth BWP domain.

The sequence of the plurality of information fields can be determined from front to back according to the sequence of the bits occupied by the plurality of information fields, that is, the bit occupied by the jth information field is before the bit occupied by the (j + 1) th information field. However, the order of the plurality of scheduled cells will be described in the following embodiments.

It should be noted that, for multiple information fields of the same type, the number of corresponding bits of each information field may be the same or different, and may also be 0, which may be specifically determined according to a mechanism in the communication protocol 38.212[2], and this disclosure is not described herein again.

Taking 8 bits occupied by 4 information fields of the same type as an example, if the number of corresponding bits of the information fields is different, the 1 st information field may correspond to the 1 st and 2 nd bits (i.e. bit index)

Corresponding to 2 bits), the 2 nd information field corresponds to the 3 rd to 5 th bits (i.e., bit index)

Corresponding to 3 bits),the 3 rd information field corresponds to the 6 th and 7 th bits (i.e., bit index)

Corresponding to 2 bits), the 4 th information field corresponds to the 8 th bit (i.e., bit index)

Corresponding to 1 bit); if the number of bits corresponding to the information fields is the same, the number of bits corresponding to the 1 st information field may be 1 st bit and 2 nd bit, the number of bits corresponding to the 2 nd information field may be 3 rd bit and 4 th bit, the number of bits corresponding to the 3 rd information field may be 5 th bit and 6 th bit, the number of bits corresponding to the 4 th information field may be 7 th bit and 8 th bit, that is, each information field may correspond to 2 bits (i.e., bit index)

Corresponding to 2 bits).

The predefined rule specifies the association relationship between the cell and other cells and the information field when the terminal receives the DCI according to the same rule, and how to determine the order of the plurality of scheduled cells.

In one embodiment, the predefined rule specifies that the identity of the jth scheduled cell is less than the identity of the jth +1 scheduled cell, i.e. k _j Less than k _j+1 (ii) a Or, the predefined rule specifies that the identity of the jth scheduled cell is greater than the identity of the jth +1 scheduled cell, i.e. k _j Greater than k _j+1 。

Regarding the identifier (e.g., Cell ID) of the scheduled Cell, the terminal may determine according to an RRC signaling sent by the network device, for example, according to Information Elements (IEs) such as serviceindex and/or SCellIndex in the RRC signaling; if the Cell Identity corresponds to a PCI (Physical Cell Identity), the Cell Identity can be determined according to an information element physcellld in the RRC signaling; of course, the determination may be based on other signaling. Or determined according to other means, such as may be specified by predefined rules.

The predefined rule may rank the scheduled cells according to their identities, for example, the identities may be ranked from small to large, and then the identity of the jth scheduled cell is smaller than the identity of the (j + 1) th scheduled cell, or the identities may be ranked from large to small, and then the identity of the jth scheduled cell is larger than the identity of the (j + 1) th scheduled cell.

For example, 4 scheduled cells are taken as an example, cell #1 identified as 1, cell #2 identified as 2, cell #3 identified as 3, and cell #4 identified as 4. If the sequence is from small to large according to the identification, k is _j Less than k _j+1 It can be determined that the 1 st cell is cell #1, the 2 nd scheduled cell is cell #2, the 3 rd cell is cell #3, and the 4 th cell is cell # 4; if the sequence is from big to small according to the mark, k _j Greater than k _j+1 It can be determined that the 1 st cell is cell #4, the 2 nd scheduled cell is cell #3, the 3 rd cell is cell #2, and the 4 th cell is cell # 1.

Therefore, the sequencing of the cells can be accurately determined according to the identification of the cells, and the jth scheduled cell scheduled in the jth information field can be specifically the cell.

In one embodiment, the predefined rule specifies that the center frequency of the jth scheduled cell is less than the center frequency of the jth +1 scheduled cell; alternatively, the predefined rule specifies that the center frequency of the jth scheduled cell is greater than the center frequency of the (j + 1) th scheduled cell.

Regarding the central frequency of the scheduled cell, the terminal may determine according to information sent by the network device, for example, according to a synchronization Signal block ssb (synchronization Signal block) sent by the network device; of course, it may also be determined in other ways, e.g. as may be specified by predefined rules.

The predefined rule may rank the scheduled cells according to their center frequencies, for example, the rank may be from small to large according to the center frequency, and then the center frequency of the jth scheduled cell is smaller than the center frequency of the (j + 1) th scheduled cell, or the rank may be from large to small according to the center frequency, and then the center frequency of the jth scheduled cell is larger than the center frequency of the (j + 1) th scheduled cell.

For example, taking 4 scheduled cells as an example, 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 > f 4. If the central frequencies are sorted from small to large, the 1 st cell is a cell #4, the 2 nd scheduled cell is a cell #3, the 3 rd cell is a cell #2, and the 4 th cell is a cell # 1; if the central frequencies are sorted from large to small, the 1 st cell is cell #1, the 2 nd scheduled cell is cell #2, the 3 rd cell is cell #3, and the 4 th cell is cell # 4.

Therefore, the sequencing of the cells can be accurately determined according to the center frequency of the cells, and the jth scheduled cell scheduled in the jth information field can be specifically the cell.

In one embodiment, the predefined rule specifies that ARFCN (Absolute Radio Frequency Channel Number, specifically NR-ARFCN) corresponding to the center Frequency of the jth scheduled cell is smaller than ARFCN corresponding to the center Frequency of the jth +1 scheduled cell; or, the predefined rule specifies that the ARFCN corresponding to the center frequency of the jth scheduled cell is greater than the ARFCN corresponding to the center frequency of the jth +1 scheduled cell.

Regarding the ARFCN of the scheduled cell, the terminal may be determined according to the center frequency of the scheduled cell, or may be determined in other manners.

The predefined rule may order the scheduled cells according to their ARFCNs, for example, the ARFCNs may be ordered from small to large, and then the ARFCN of the jth scheduled cell is smaller than the ARFCN of the jth +1 scheduled cell, or the ARFCNs may be ordered from large to small, and then the ARFCN of the jth scheduled cell is larger than the ARFCN of the jth +1 scheduled cell.

For example, 4 scheduled cells are taken as an example, ARFCN of cell #1 is ARFCN #1, ARFCN of cell #2 is ARFCN #2, ARFCN of cell #3 is ARFCN #3, and ARFCN of cell #4 is ARFCN #4, where ARFCN #1 > ARFCN #2 > ARFCN #3 > ARFCN # 4. If the ARFCNs are sorted from small to large, the 1 st cell is a cell #4, the 2 nd scheduled cell is a cell #3, the 3 rd cell is a cell #2, and the 4 th cell is a cell # 1; if the ARFCNs are sorted from large to small, the 1 st cell is cell #1, the 2 nd scheduled cell is cell #2, the 3 rd cell is cell #3, and the 4 th cell is cell # 4.

Therefore, the sequencing of the cells can be accurately determined according to the ARFCNs of the cells, and the jth scheduled cell scheduled by the jth information domain can be specifically the cell.

In one embodiment, the plurality of information fields includes n information fields, and the plurality of scheduled cells includes a cell in which the terminal receives the DCI and n-1 other cells; the predefined rule specifies that the 1 st information domain of the n information domains is associated with a cell where the terminal is located when receiving the DCI, and the 2 nd to the ith information domains of the n information domains are associated with the i-1 th other cells of the n-1 other cells, wherein i is more than or equal to 2 and less than or equal to n.

The scheduled cell may include a cell in which the terminal receives the DCI and other cells (cells other than the cell in which the terminal receives the DCI in the scheduled cell), or may include only other cells, excluding the cell in which the terminal receives the DCI. In this embodiment, the predefined rule may distinguish a cell and other cells where the terminal receives the DCI when specifying the association between the scheduled cell and the information field, and specify the association between the cell and other cells where the terminal receives the DCI and the information field according to different rules.

Taking n scheduled cells as an example, if the n scheduled cells include the cell where the terminal receives the DCI and n-1 other cells. For a certain type of information field, n information fields may be set to schedule the n scheduled cells, and the association relationship may be that the 1 st information field of the n information fields is associated with a cell where the terminal receives the DCI, and the ith information field of the 2 nd to nth information fields is associated with the i-1 th other cell of the n-1 other cells. That is, for n-1 other cells, the association relationship between the cell and the information field is defined according to the same rule, and for the cell where the terminal receives the DCI, the association with the 1 st information field is defined.

Accordingly, the terminal can determine that the scheduling information indicated by the value of the 1 st information field is the scheduling information of the cell in which the terminal receives the DCI, and from the 2 nd information field to the nth information field, the scheduling information indicated by the value of the ith information field is the scheduling information of the i-1 th other cell, so that the scheduling information of each cell can be accurately determined on the basis of scheduling a plurality of cells through one DCI. The number of bits occupied by the ith information domain and the specific indication mode are the same as the mode of scheduling a single cell by using single DCI.

For example, for n scheduled cells from the 1 st cell to the nth scheduled cell, if the n scheduled cells include a cell in which the terminal is located when receiving the DCI and n-1 other cells, taking the seperate indication manner adopted by the FDRA field as an example, n FDRA fields may be set in the DCI, and the predefined rule may specify that the 1 st FDRA field of the n FDRA fields is associated with the cell in which the terminal is located when receiving the DCI, and in the n-1 FDRA fields of the nth FDRA fields from the 2 nd FDRA field to the nth FDRA field, the ith information field is associated with the i-1 st other cell. If the cell id of the cell where the terminal receives the DCI is not in k ₁ To k is _n-1 Then the cell id of the i-1 th scheduled cell may be k _i-1 。

In this embodiment, the terminal may determine that the 1 st FDRA domain indicates the frequency domain scheduling information of the cell in which the terminal is located when receiving the DCI, and in n-1 FDRA domains of the nth FDRA domain from the 2 nd FDRA domain, the 2 nd FDRA domain indicates the 1 st other cell (cell k) ₁ ) …, the ith FDRA field indicates the (i-1) th other cell (cell k) _i-1 ) …, the nth FDRA field indicates the (n-1) th other cell (cell k) _n-1 ) The frequency domain scheduling information of each cell indicated by the DCI can be accurately interpreted by the terminal on the basis of scheduling a plurality of cells through one DCI.

The number of bits occupied by the ith FDRA domain is determined according to a mechanism in a communication protocol 38.212[2], namely: and determining the bits occupied by the ith FDRA domain and the corresponding relation between the value indicated by the FDRA domain and the frequency domain resource based on the resource allocation type ('type 0', 'type 1', 'dynamic') indicated by the high-level configuration signaling of the ith scheduled cell.

For example, for n scheduled cells from the 1 st cell to the nth scheduled cell, if the n scheduled cells include a cell in which the terminal is located when receiving the DCI and n-1 other cells, taking a separate indication manner adopted by the ZP CSI-RS trigger domain as an example, n ZP CSI-RS trigger domains may be set in the DCI, a predefined rule may specify that the 1 st ZP CSI-RS trigger domain of the n ZP CSI-RS trigger domains is associated with the cell in which the terminal is located when receiving the DCI, and in n-1 FDRA domains of the nth ZP CSI-RS trigger domain from the 2 nd ZP CSI-RS trigger domain, the ith information domain is associated with the i-1 th other cell. If the cell id of the cell where the terminal receives the DCI is not in k ₁ To k is _n-1 Then the cell id of the i-1 th scheduled cell may be k _i-1 。

In this embodiment, the terminal may determine ZP CSI-RS trigger information of a cell where the 1 st ZP CSI-RS trigger domain indicates that the terminal is located when receiving the DCI, and in n-1 ZP CSI-RS triggers of an nth BWP indication domain from the 2 nd ZP CSI-RS trigger domain, the 2 nd ZP CSI-RS trigger domain indicates the 1 st other cell (cell k) ₁ ) The ZP CSI-RS trigger information, … and the ith ZP CSI-RS trigger domain indicate the (i-1) th other cell (cell k) _i-1 ) The ZP CSI-RS trigger information, … and the nth ZP CSI-RS trigger domain indicate the nth-1 other cells (cell k) _n-1 ) The ZP CSI-RS trigger information enables the terminal to accurately interpret the ZP CSI-RS trigger information of each cell indicated by the DCI on the basis of scheduling a plurality of cells through one DCI.

The number of bits occupied by the ith ZP CSI-RS trigger domain is determined according to a mechanism in a communication protocol 38.212[2], namely: and determining the number of bits occupied by the ith ZP CSI-RS trigger domain based on the number nZP of the high-level configuration ZP CSI-RS resource sets of the ith scheduled cell.

E.g. for 1 st cell to nthIf the n scheduled cells include a cell in which the terminal receives the DCI and n-1 other cells, taking a partial indication manner adopted by the BWP indication domain as an example, n BWP indication domains may be set in the DCI, and the predefined rule may specify that the 1 st BWP indication domain of the n BWP indication domains is associated with the cell in which the terminal receives the DCI, and that the i-th information domain of the n FDRA domains from the 2 nd BWP indication domain to the n-th BWP indication domain is associated with the i-1 th other cell. If the cell id of the cell where the terminal receives the DCI is not in k ₁ To k is _n-1 Then the cell id of the i-1 th scheduled cell may be k _i-1 。

In this embodiment, the terminal may determine BWP information of a cell in which the 1 st BWP indication domain indicates that the terminal receives the DCI, and in n-1 BWP indication domains of the nth BWP indication domain from the 2 nd BWP indication domain, the 2 nd BWP indication domain indicates the 1 st other cell (cell k) ₁ ) Indicates the i-1 th other cell (cell k) in the i-th BWP indication field of the BWP information (…) _i-1 ) Indicates the n-1 th other cell (cell k) in the BWP information of (…) and the nth BWP indication field _n-1 ) Thereby, on the basis of scheduling a plurality of cells through one DCI, the terminal can accurately interpret the BWP information of each cell indicated by the DCI.

The number of bits occupied by the ith BWP domain is determined according to a mechanism in a communication protocol 38.212[2], that is: and based on the high-layer configuration BWP number nBWP of the ith scheduled cell, the RRC determines the number of bits occupied by the ith BWP domain.

The sequence of the plurality of information fields can be determined from front to back according to the sequence of the bits occupied by the plurality of information fields, that is, the bit occupied by the i-1 th information field is before the bit occupied by the i-th information field. However, the order of the plurality of scheduled cells will be described in the following embodiments.

The following illustrates, by way of example, several embodiments, how the predefined rule specifies, according to different rules, the association relationship between the cell where the terminal receives the DCI and other cells and the information field, and the order of the plurality of scheduled cells.

In one embodiment, the predefined rule specifies that the identity of the i-1 st other cell is less than the identity of the i-th other cell; alternatively, the predefined rule specifies that the identity of the (i-1) th other cell is greater than the identity of the (i) th other cell.

Regarding the identifier (e.g., Cell ID) of the scheduled Cell, the terminal may determine according to the RRC signaling sent by the network device, for example, according to IE such as ServcellIndex and/or scelllindex in the RRC signaling; the identity of the cell corresponds to the PCI, which can be determined according to the information element physcellld in the RRC signaling; of course, it may also be determined in other ways, e.g. as may be specified by predefined rules.

The predefined rule may rank the scheduled cells according to their identities, for example, the scheduled cells may be ranked from small to large according to their identities, where the cell in which the terminal receives the DCI is the 1 st cell, the identity of the i-1 st other cell is smaller than the identity of the i-th other cell, and if the cell id of the cell in which the terminal receives the DCI is not k ₁ To k is _n-1 K is _i-1 Less than k _i (ii) a Or the cells can be sorted according to the identifiers from big to small, the cell in which the terminal receives the DCI is the 1 st cell, the identifier of the (i-1) th other cell is larger than that of the (i) th other cell, and if the cell id of the cell in which the terminal receives the DCI is not at k ₁ To k is _n-1 K is _i-1 Greater than k _i 。

For example, 4 scheduled cells are taken as an example, which are cell #1 with identifier 1, cell #2 with identifier 2, cell #3 with identifier 3 and cell #4 with identifier 4, respectively, where cell #3 is a cell in which the terminal receives the DCI. If the cell is sorted from small to large according to the identifier, the 1 st cell is cell #3, and k is set for other cells except for cell #3 _i-1 Less than k _i The 2 nd scheduled cell is cell #1, the 3 rd cell is cell #2, and the 4 th cell is cell # 4; if the cell is sorted from large to small according to the identifier, the 1 st cell is cell #3, and k is set for other cells except for cell #3 _i-1 Greater than k _i The 2 nd scheduled cell is a cell#4, cell #2 for cell 3, and cell #1 for cell 4.

Therefore, the sequencing of the cells can be accurately determined according to the identification of the cells, and the ith scheduled cell scheduled in the ith information domain can be specifically the cell.

In one embodiment, the predefined rule specifies that the center frequency of the (i-1) th other cell is less than the center frequency of the (i) th other cell; alternatively, the predefined rule specifies that the center frequency of the (i-1) th other cell is greater than the center frequency of the (i) th other cell.

Regarding the center frequency of the scheduled cell, the terminal may determine according to information sent by the network device, for example, according to a synchronization signal block SSB sent by the network device; of course, it may also be determined in other ways, e.g. as may be specified by predefined rules.

The predefined rule may rank the scheduled cells according to their center frequencies, for example, the scheduled cells may be ranked from small to large according to their center frequencies, so that the cell in which the terminal receives the DCI is the 1 st cell, and the center frequency of the i-1 st other cell is smaller than the center frequency of the i-th other cell; or the DCI may be sorted according to the ascending center frequency, the cell where the terminal receives the DCI is the 1 st cell, and the center frequency of the i-1 st other cell is greater than the center frequency of the i-th other cell.

For example, 4 scheduled cells are taken as an example, 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, and cell #3 is the cell where the terminal receives the DCI. If the central frequencies are sorted from small to large, the 1 st cell is a cell #3, the 2 nd scheduled cell is a cell #4, the 3 rd cell is a cell #2, and the 4 th cell is a cell # 1; if the central frequencies are sorted from large to small, the 1 st cell is cell #3, the 2 nd scheduled cell is cell #1, the 3 rd cell is cell #2, and the 4 th cell is cell # 4.

Therefore, the sequencing of the cells can be accurately determined according to the center frequency of the cells, and the ith scheduled cell scheduled in the ith information domain can be specifically determined to be which cell.

In one embodiment, the predefined rule specifies that the absolute radio frequency channel number ARFCN corresponding to the center frequency of the i-1 st other cell is less than the ARFCN corresponding to the center frequency of the i-th other cell; alternatively, the predefined rule specifies that the ARFCN corresponding to the center frequency of the i-1 st other cell is greater than the ARFCN corresponding to the center frequency of the i-th other cell.

The predefined rule may rank the scheduled cells according to their ARFCNs, for example, the scheduled cells may be ranked from small to large according to their ARFCNs, so that the cell in which the terminal receives the DCI is the 1 st cell, and the ARFCN of the i-1 st other cell is smaller than the ARFCN of the i-th other cell; or the ARFCNs can be sorted from big to small, the cell where the terminal receives the DCI is the 1 st cell, and the ARFCN of the (i-1) th other cell is larger than that of the ith other cell.

For example, 4 scheduled cells are taken as an example, ARFCN of cell #1 is ARFCN #1, ARFCN of cell #2 is ARFCN #2, ARFCN of cell #3 is ARFCN #3, and ARFCN of cell #4 is ARFCN #4, where ARFCN #1 > ARFCN #2 > ARFCN #3 > ARFCN #4, and cell #3 is a cell in which the terminal receives the DCI. If the ARFCNs are sorted from small to large, the 1 st cell is a cell #3, the 2 nd scheduled cell is a cell #4, the 3 rd cell is a cell #2, and the 4 th cell is a cell # 1; if the ARFCNs are sorted from large to small, the 1 st cell is cell #3, the 2 nd scheduled cell is cell #1, the 3 rd cell is cell #2, and the 4 th cell is cell # 4.

Therefore, the sequencing of the cells can be accurately determined according to the ARFCNs of the cells, and the ith scheduled cell scheduled by the ith information domain can be specifically determined to be which cell.

Fig. 2 is a schematic flowchart illustrating a downlink control information transmitting method according to an embodiment of the disclosure. The downlink control information sending method shown in this embodiment may be applied to a network device, 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. 2, the downlink control information sending method may include the following steps:

in step S201, determining an association relationship between a plurality of information fields of the same type in downlink control information DCI for scheduling a plurality of cells and a plurality of scheduled cells;

in step S202, DCI is generated according to the association relationship;

in step S203, the generated DCI is transmitted to the terminal.

In one embodiment, various types of information fields may be included in the DCI, such as an FDRA field, a ZP CSI-RS trigger field, a partial bandwidth indication field, and the like.

In the existing DCI, only one information field of the same type is generally included, and a cell may be scheduled according to the information field of the type, for example, the FDRA information field may schedule frequency domain resources of the cell.

The embodiment can be applied to a scenario where one DCI schedules multiple cells. In this embodiment, the network device may determine an association relationship between multiple information fields of the same type and multiple scheduled cells, and set the information field of each cell according to the association relationship, thereby generating DCI, and sending the DCI to the terminal, thereby implementing scheduling of multiple cells. The information fields of the same type are correspondingly indicated with the same information type, for example, frequency domain resources FDRA indicating different cells, for example, BWP indexes indicating different cell configurations, as described in detail below.

Such an indication manner may be referred to as separate indication, for example, a specific type information field in one DCI may include a plurality of information fields. On the basis of scheduling the information domain in one DCI of a single cell, corresponding bit extension can be carried out on the information domain of a specific type according to the number of the scheduled cells, so that a plurality of information domains of the same type can be obtained, wherein different information domains indicate messages of different cells. The number of bits occupied by a plurality of information domains of the same type in one DCI is equal to the sum of the number of bits occupied by the information domains corresponding to each dispatched cell. The number of bits occupied by the information domain corresponding to each scheduled cell is the same as the number of bits occupied by the same type of information domain of DCI scheduled for one cell in the existing mechanism.

As shown in fig. 1B, taking the BWP indication fields as an example, one DCI for scheduling 3 cells (cell id numbers are 0, 1, and 2, respectively) includes 3 BWP indication fields, and the 3 BWP indication fields occupy 5bits, for example, a value of 01100.

Wherein the 1 st and 2 nd bits (01) correspond to cell 0, so the BWP id of cell 0 can be determined to be 2 from the 1 st and 2 nd bits (01); the 3 rd and 4 th bits (10) correspond to cell 1, and thus BWP id of cell 1 may be determined to be 3 from the 3 rd and 4 th bits (10); the 5 th bit (0) corresponds to cell 0, and thus BWP id of cell 2 may be determined to be 1 from the 5 th bit (0).

For the specific type of information domain in the DCI for scheduling multiple cells, if the specific type of information domain uses a separate mode, the specific type of information domain may include multiple information domains, and the corresponding indexes of the multiple information domain occupied bits are:

Corresponding bits for the 1 st information domain for indicating the cell k ₀ Scheduling information, index of

Corresponding bits for ith information field for indicating cell k _i Scheduling information, index of

Correspondingly, the terminal can determine the incidence relation between a plurality of information domains of the same type and a plurality of scheduled cells, and further determine the scheduled cell corresponding to each information domain according to the incidence relation, so that the scheduling information of the scheduled cell can be determined according to the value of the information domain corresponding to the scheduled cell, and finally the corresponding scheduled cell can be scheduled through the scheduling information. Therefore, the scheduling information of each cell is accurately determined on the basis of scheduling a plurality of cells through one DCI.

Since multiple types of information fields may be set in the DCI, for any one or several types of information fields, multiple information fields may be set in a separate manner to implement scheduling for multiple cells, and specifically, what type or types of information fields are set may be determined according to a predefined rule or according to a signaling instruction. For example, for the FDRA field and the BWP indication field, the signaling indicates that the FDRA field is indicated based on the separate manner, and then multiple FDRA fields may be set in DCI for multiple scheduled cells; for example, the predefined rule specifies a separate-based manner indication for both FDAR domain and BWP domain, then multiple FDRA domains and multiple BWP indication domains may be set in DCI for multiple scheduled cells.

It should be noted that, regarding the number of the multiple cells scheduled by the DCI and/or the cell numbers corresponding to the multiple cells, that is, the multiple scheduled cells, the terminal may be determined according to the CIF in the DCI, may also be pre-agreed with the network device, and may also be determined according to a predefined rule (e.g., agreement), which is not limited in the present disclosure.

In an embodiment, the determining the association relationship between a plurality of information fields of the same type in downlink control information DCI for scheduling a plurality of cells and a plurality of scheduled cells includes: and determining the association relation according to a predefined rule.

In an embodiment, the determining the association relationship between a plurality of information fields of the same type in downlink control information DCI for scheduling a plurality of cells and a plurality of scheduled cells includes: determining the association relationship according to the implementation of the network device; wherein the method further comprises: and indicating the association relation to the terminal.

The association relationship between multiple information fields of the same type in DCI and multiple scheduled cells may be specified by a predefined rule, e.g., a protocol convention; or the network device may determine as needed and then indicate the association relationship to the terminal, where the manner in which the network device indicates the association relationship includes, but is not limited to, indicating through RRC signaling, indicating through DCI, and indicating through MAC CE.

In one embodiment, the plurality of information fields includes n information fields, and the plurality of scheduled cells includes n scheduled cells; the predefined rule specifies that a jth information domain of the n information domains is associated with a jth scheduled cell of the n scheduled cells, wherein j is greater than or equal to 1 and less than or equal to n.

Accordingly, the terminal can determine the scheduling information indicated by the value of the jth information field as the scheduling information of the jth scheduled cell, thereby accurately determining the scheduling information of each cell on the basis of scheduling a plurality of cells through one DCI. The number of bits occupied by the jth information domain and the specific indication mode are the same as the mode of a single DCI scheduling single cell.

For example, for n scheduled cells from the 1 st cell to the nth scheduled cell, taking the FDRA field with the separate indication manner as an example, n FDRA fields may be set in the DCI, and the predefined rule may specify that the jth information field of the n information fields is associated with the jth scheduled cell of the n scheduled cells, where the cell id of the jth scheduled cell may be k _j . In this embodiment, the terminal may determine that the 1 st FDRA domain indicates the 1 st scheduled cell (cell k) ₁ ) The 2 nd FDRA field indicates the 2 nd scheduled cell (cell k) ₂ ) …, the jth FDRA field indicates the jth scheduled cell (cell k) _j ) …, the nth FDRA field indicates the nth scheduled cell (cell k) _n ) The frequency domain scheduling information of the method enables the network equipment to accurately determine the frequency domain scheduling information of each cell on the basis of scheduling a plurality of cells through one DCI, and then generates the DCI to realize the scheduling of each cell.

The number of bits occupied by the jth FDRA domain is determined according to a mechanism in a communication protocol 38.212[2], namely: and determining the bits occupied by the jth FDRA domain and the corresponding relation between the value indicated by the FDRA domain and the frequency domain resource based on the resource allocation type ('type 0', 'type 1', 'dynamic') indicated by the high-level configuration signaling of the jth scheduled cell.

For example, for n scheduled cells from the 1 st cell to the nth scheduled cell, taking the ZP CSI-RS trigger field as an example of using the separate indication manner, n ZP CSI-RS trigger fields may be set in the DCI, and the predefined rule may specify that the jth information field of the n information fields is associated with the jth scheduled cell of the n scheduled cells, where the cell id of the jth scheduled cell may be k _j . In this embodiment, the terminal may determine that the 1 st ZP CSI-RS trigger domain indicates the 1 st scheduled cell (cell k) ₁ ) The ZP CSI-RS trigger information and the 2 nd ZP CSI-RS trigger domain indicate the 2 nd scheduled cell (cell k) ₂ ) The ZP CSI-RS trigger information and … of the jth ZP CSI-RS trigger field indicate the jth scheduled cell (cell k) _j ) The ZP CSI-RS trigger information, … and the nth ZP CSI-RS trigger domain indicate the nth scheduled cell (cell k) _n ) The ZP CSI-RS trigger information enables the network equipment to accurately determine the ZP CSI-RS trigger information of each cell on the basis of scheduling a plurality of cells through one DCI, and then DCI is generated to realize scheduling of each cell.

The number of bits occupied by the jth ZP CSI-RS trigger domain is determined according to a mechanism in a communication protocol 38.212[2], namely: and determining the number of bits occupied by the jth ZP CSI-RS trigger domain based on the number nZP of the high-level configuration ZP CSI-RS resource sets of the jth scheduled cell.

For example, for n scheduled cells from 1 st cell to nth scheduled cell, taking the way of separate indication for BWP indication fields as an example, n BWP indication fields may be set in DCI, and the predefined rule may specify that the jth information field of the n information fields is associated with the jth scheduled cell of the n scheduled cells, where the cell id of the jth scheduled cell may be k _j . In this embodiment, the terminal may determine that the 1 st BWP indication field indicates the 1 st scheduled cell (cell k) ₁ ) BWP information of (2), 2 nd BWP indication field indicates 2 nd scheduled cell (cell k) ₂ ) …, the jth BWP indication field indicates the jthScheduled cell (cell k) _j ) The nth BWP indication field indicates the nth scheduled cell (cell k), … _n ) Based on scheduling multiple cells through one DCI, the network device may accurately determine BWP information of each cell, and generate DCI to implement scheduling for each cell.

The sequence of the plurality of information fields can be determined from front to back according to the sequence of the bits occupied by the plurality of information fields, that is, the bit occupied by the jth information field is before the bit occupied by the (j + 1) th information field. And, with regard to the order of the plurality of scheduled cells, how to determine is explained in the following embodiments.

It should be noted that, for a plurality of information fields of the same type, the number of corresponding bits of each information field may be the same or different, and may also be 0, which may specifically be determined according to a mechanism in the communication protocol 38.212[2], and this disclosure is not described herein again.

The 4 information fields of the same type occupy 8 bits, and if the number of corresponding bits of the information fields is different, the 1 st information field may correspond to the 1 st and 2 nd bits (i.e. bit index)

Corresponding to 3 bits), the 3 rd information field corresponds to the 6 th and 7 th bits (i.e., bit index)

Corresponding to 2 bits), and the 4 th information field corresponds to the 8 th bit (i.e., bit index)

Corresponding to 1 bit); if the number of bits corresponding to the information fields is the same, the 1 st information field may correspond to the 1 st and 2 nd bits, the 2 nd information field may correspond to the 3 rd and 4 th bits, the 3 rd information field may correspond to the 5 th and 6 th bits, and the 4 th information field may correspond to the 7 th and 8 th bits, that is, each information field may correspond to 2 bits (i.e., bit index)

Corresponding to 2 bits).

Regarding the identity (e.g., Cell ID) of the scheduled Cell, the network device may perform indication through RRC signaling, for example, through IE indication such as ServcellIndex and/or scelllindex in the RRC signaling; if the cell identifier corresponds to the PCI, the cell identifier may be indicated by an information element physcellld in RRC signaling; of course, the terminal may also be determined from other signaling. Or determined according to other means, such as may be specified by predefined rules.

For example, 4 scheduled cells are taken as an example, and are respectively cell #1 and beacon labeled as 1Cell #2 identified as 2, cell #3 identified as 3, and cell #4 identified as 4. If the sequence is from small to large according to the identification, k is _j Less than k _j+1 It can be determined that the 1 st cell is cell #1, the 2 nd scheduled cell is cell #2, the 3 rd cell is cell #3, and the 4 th cell is cell # 4; if the sequence is from big to small according to the mark, k _j Greater than k _j+1 It can be determined that the 1 st cell is cell #4, the 2 nd scheduled cell is cell #3, the 3 rd cell is cell #2, and the 4 th cell is cell # 1.

Therefore, the sequencing of the cells can be accurately determined according to the cell identifiers, and the jth scheduled cell scheduled in the jth information field is specifically the cell.

The network equipment indicates the center frequency of the scheduled cell by sending an SSB to the terminal; of course, the terminal may also be determined according to other ways, e.g. as may be specified by predefined rules.

Therefore, the sequencing of the cells can be accurately determined according to the center frequency of the cells, and the jth scheduled cell scheduled in the jth information domain can be specifically the cell.

In one embodiment, the predefined rule specifies that the absolute radio frequency channel number ARFCN corresponding to the center frequency of the jth scheduled cell is less than the ARFCN corresponding to the center frequency of the jth +1 scheduled cell; or, the predefined rule specifies that the ARFCN corresponding to the center frequency of the jth scheduled cell is greater than the ARFCN corresponding to the center frequency of the jth +1 scheduled cell.

Regarding the ARFCN of the scheduled cell, the network device may be determined according to the center frequency of the scheduled cell, or may be determined in other manners.

The predefined rule may order the scheduled cells according to their ARFCNs, for example, the ARFCNs may be ordered from small to large, such that the ARFCN of the jth scheduled cell is smaller than the ARFCN of the jth +1 scheduled cell, or the ARFCNs may be ordered from large to small, such that the ARFCN of the jth scheduled cell is greater than the ARFCN of the jth +1 scheduled cell.

Therefore, the sequencing of the cells can be accurately determined according to the ARFCN of the cells, and the jth scheduled cell scheduled by the jth information domain can be specifically the cell.

In one embodiment, the plurality of information fields includes n information fields, and the plurality of scheduled cells includes a cell in which the terminal receives the DCI and n-1 other cells; the predefined rule specifies that the 1 st information domain of the n information domains is associated with a cell where the terminal is located when receiving the DCI, and the 2 nd to ith information domains are associated with the i-1 th other cells of the n-1 other cells, wherein i is more than or equal to 2 and less than or equal to n.

The scheduled cell may include a cell in which the terminal receives the DCI and other cells (cells other than the cell in which the terminal receives the DCI in the scheduled cell), or may include only other cells, excluding the cell in which the terminal receives the DCI. In this embodiment, the predefined rule may distinguish a cell where the terminal receives the DCI from other cells when the association between the scheduled cell and the information field is defined, and define the association between the cell where the terminal receives the DCI from other cells and the information field according to different rules.

Accordingly, the network device may determine that the scheduling information indicated by the value of the 1 st information field is the scheduling information of the cell in which the terminal receives the DCI, and from the 2 nd information field to the nth information field, the scheduling information indicated by the value of the i-th information field is the scheduling information of the i-th other cell, so that the scheduling information of each cell is accurately determined on the basis of scheduling a plurality of cells through one DCI. The number of bits occupied by the ith information domain and the specific indication mode are the same as the mode of scheduling a single cell by using single DCI.

For example, for n scheduled cells from the 1 st cell to the nth scheduled cell, if the n scheduled cells include a cell where the terminal is located when receiving the DCI and n-1 other cells, taking a default indication manner for the FDRA domain as an example, n FDRA domains may be set in the DCI, a predefined rule may specify that the 1 st FDRA domain of the n FDRA domains is associated with the cell where the terminal is located when receiving the DCI, in the n-1 FDRA domains of the n FDRA domains from the 2 nd FDRA domain to the nth FDRA domain, the i-th information domain is associated with the i-1 st other cell, and if the terminal receives the DCI, the cell id of the cell where the terminal is located is not k ₁ To k is _n-1 Then the cell id of the i-1 th scheduled cell may be k _i-1 。

In this embodiment, the terminal may determine frequency domain scheduling information of a cell where the 1 st FDRA domain indicates that the terminal is located when receiving the DCI, and in n-1 FDRA domains of the nth FDRA domain from the 2 nd FDRA domain, the 2 nd FDRA domain indicates the 1 st other cell (cell k) ₁ ) …, the ith FDRA field indicates the (i-1) th other cell (cell k) _i-1 ) …, the nth FDRA field indicates the (n-1) th other cell (cell k) _n-1 ) The frequency domain scheduling information of (a), thereby enabling the network device to be able to accurately interpret the cell corresponding to each FDRA domain indicated by the DCI on the basis of scheduling the multiple cells by using one DCI.

For example, for n scheduled cells from the 1 st cell to the nth scheduled cell, if the n scheduled cells include a cell where the terminal is located when receiving the DCI and n-1 other cells, taking a default indication manner of the ZP CSI-RS trigger domain as an example, n ZP CSI-RS trigger domains may be set in the DCI, and the predefined rule may specify n ZP CSI-RS trigger domainsIn the 1 st ZP CSI-RS trigger domain in the ZP CSI-RS trigger domains and the cell where the terminal is located when receiving the DCI, in n-1 FDRA domains of the nth ZP CSI-RS trigger domain from the 2 nd ZP CSI-RS trigger domain, the ith information domain is associated with the (i-1) th other cells, if the cell id of the cell where the terminal is located is not located at k when receiving the DCI ₁ To k to _n-1 Then the cell id of the i-1 th scheduled cell may be k _i-1 。

In this embodiment, the terminal may determine ZP CSI-RS trigger information of a cell in which the 1 st ZP CSI-RS trigger domain indicates that the terminal receives the DCI, and in n-1 ZP CSI-RS triggers of an nth BWP indication domain from the 2 nd ZP CSI-RS trigger domain, the 2 nd ZP CSI-RS trigger domain indicates a 1 st other cell (cell k) ₁ ) The ZP CSI-RS trigger information and … of the ith ZP CSI-RS trigger domain indicate the ith-1 other cells (cell k) _i-1 ) The ZP CSI-RS trigger information, … and the nth ZP CSI-RS trigger domain indicate the nth-1 other cells (cell k) _n-1 ) The ZP CSI-RS trigger information enables the network equipment to accurately interpret the cells corresponding to each ZP CSI-RS trigger domain indicated by the DCI on the basis of scheduling the plurality of cells through the DCI.

For example, for n scheduled cells from the 1 st cell to the nth scheduled cell, if the n scheduled cells include a cell where the terminal is located when receiving the DCI and n-1 other cells, taking a default indication manner for the BWP indication fields as an example, n BWP indication fields may be set in the DCI, a predefined rule may specify that the 1 st BWP indication field of the n BWP indication fields is associated with the cell where the terminal is located when receiving the DCI, in n-1 FDRA fields of the n BWP indication fields from the 2 nd BWP indication field to the nth BWP indication field, the i-th information field is associated with the i-1 th other cell, and if the terminal receives the DCI, the cell id of the cell where the terminal is located is not at k ₁ To k is _n-1 Then the i-1 th scheduled cellMay be k _i-1 。

In this embodiment, the terminal may determine BWP information of a cell in which the 1 st BWP indication domain indicates that the terminal receives the DCI, and in n-1 BWP indication domains of the nth BWP indication domain from the 2 nd BWP indication domain, the 2 nd BWP indication domain indicates the 1 st other cell (cell k) ₁ ) Indicates the i-1 th other cell (cell k) in the i-th BWP indication field of the BWP information (…) _i-1 ) Indicates the n-1 th other cell (cell k) in the BWP information of (…) and the nth BWP indication field _n-1 ) Thereby enabling the network device to accurately indicate the corresponding cell of each BWP indication domain on the basis of scheduling multiple cells through one DCI.

The sequence of the plurality of information fields can be determined from front to back according to the sequence of the bits occupied by the plurality of information fields, that is, the bit occupied by the i-1 th information field is before the bit occupied by the i-th information field. And, with regard to the order of the plurality of scheduled cells, how to determine is explained in the following embodiments.

In one embodiment, the predefined rule specifies that the identity of the i-1 st other cell is less than the identity of the i-th other cell; alternatively, the predefined rule specifies that the identity of the i-1 st other cell is greater than the identity of the ith other cell.

Regarding the identity (e.g., Cell ID) of the scheduled Cell, the network device may perform indication through RRC signaling, for example, through IE indication such as ServcellIndex and/or scelllindex in the RRC signaling; and the identity in the cell corresponds to the PCI, it can be indicated by the information element physcellld in the RRC signaling; of course, the terminal may also be determined according to other ways, e.g. as may be specified by predefined rules.

The predefined rule may rank the scheduled cells according to their identities, for example, the scheduled cells may be ranked from small to large according to their identities, where the cell in which the terminal receives the DCI is the 1 st cell, the identity of the i-1 st other cell is smaller than the identity of the i-th other cell, and if the cell id of the cell in which the terminal receives the DCI is not k ₁ To k is _n-1 K is _i-1 Less than k _i (ii) a Or the cells can be sorted according to the identifiers from big to small, the cell in which the terminal receives the DCI is the 1 st cell, the identifier of the (i-1) th other cell is larger than that of the (i) th other cell, and if the cell id of the cell in which the terminal receives the DCI is not at k ₁ To k to _n-1 K is _i-1 Greater than.

For example, 4 scheduled cells are taken as an example, which are cell #1 with identifier 1, cell #2 with identifier 2, cell #3 with identifier 3 and cell #4 with identifier 4, respectively, where cell #3 is a cell in which the terminal receives the DCI. If the cell is sorted from small to large according to the identifier, the 1 st cell is cell #3, and k is set for other cells except for cell #3 _i-1 Less than k _i The 2 nd scheduled cell is cell #1, the 3 rd cell is cell #2, and the 4 th cell is cell # 4; if the cell is sorted from large to small according to the identifier, the 1 st cell is cell #3, and k is set for other cells except for cell #3 _i-1 Greater than k _i The 2 nd scheduled cell is cell #4, the 3 rd cell is cell #2, and the 4 th cell is cell # 1.

For example, taking 4 scheduled cells as an example, 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, and cell #3 is the cell where the terminal receives the DCI. If the central frequencies are sorted from small to large, the 1 st cell is a cell #3, the 2 nd scheduled cell is a cell #4, the 3 rd cell is a cell #2, and the 4 th cell is a cell # 1; if the central frequencies are sorted from large to small, the 1 st cell is cell #3, the 2 nd scheduled cell is cell #1, the 3 rd cell is cell #2, and the 4 th cell is cell # 4.

Therefore, the sequencing of the cells can be accurately determined according to the center frequency of the cells, and the ith scheduled cell scheduled in the ith information domain can be specifically the cell.
