In some embodiments, reference may be made to other alternative implementations described before or after the description corresponding to fig. 2A and 2B.

In some embodiments, the network device may send first downlink control information for scheduling the plurality of cells to the terminal. The first downlink control information may be referred to as MC-DCI, which may be collectively referred to as Multi-cell Downlink Control Information, or Multi-cell scheduling Downlink Control Information, for example.

In some embodiments, the first downlink control information is used to schedule the plurality of cells, which may refer to data used for the first downlink control information to schedule the plurality of cells, for example, scheduling a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), etc. of one or more cells in the plurality of cells, so as to implement scheduling of the plurality of cells by one downlink control information.

In one embodiment, the terminal may receive the first downlink control information in a scheduling cell, where the cell scheduled by the first downlink control information may be referred to as an actually scheduled cell, and the actually scheduled cell is all or a part of cells in the cells that can be scheduled by the first downlink control information.

The following illustrates, by several embodiments, a cell that can be scheduled by the first downlink control information and a cell that is actually scheduled in the present application.

In some embodiments, as shown in fig. 3, the network device may send radio resource control (Radio Resource Control, RRC) signaling to the terminal, and configure, for the terminal, a first list (list) of a cell set to which a cell that can be scheduled by the first downlink control information belongs through the RRC signaling, for example, may indicate through an information element (Information Element, IE) MC-DCI-SetofCellsToAddModList in the RRC signaling. Multiple sets of cells may be included in the first list, with different sets not containing the same cell.

In some embodiments, the cells included in the different cell sets in the first list may be different, e.g., cell set #1 in the first list includes cell #1, and then the other cell sets in the first list do not include cell #1.

In some embodiments, as shown in fig. 3, the network device may indicate a set of cells to which the cell actually scheduled by the first downlink control information belongs in the first list. For example, the network device may indicate a set in the first list via an information element DCI field Scheduled cell set indicator in RRC signaling. For example, the first list contains 4 sets, e.g. 4 sets are characterized by the following 4 information elements: MC-DCI-setofCells0, MC-DCI-setofCells1, MC-DCI-setofCells2, and MC-DCI-setofCells3. For example, the set indicated by the network device in the first list is MC-DCI-setofCells2, the terminal may determine that the set is a set of cells to which the cell actually scheduled by the first downlink control information belongs.

In some embodiments, for the first downlink control information, it may be further divided into first downlink control information for scheduling PUSCH, for example, referred to as MC-DCI 0_3, and first downlink control information for scheduling PDSCH, for example, referred to as MC-DCI 1_3. The MC-DCI 0_3 and MC-DCI 0_3 refer to a format of MC-DCI, and may be a downlink control information format newly added on the basis of a conventional (legacy) downlink control information format. The legacy downlink control information may refer to downlink control information for scheduling a single cell.

In some embodiments, such as shown in fig. 3, for MC-DCI 0_3, the network device may indicate to the terminal, via an information element schedule cell-listdi-0-3 in RRC signaling, the set of cells to which the cell actually scheduled by MC-DCI 0_3 belongs. The set of cells to which the cell actually scheduled by the MC-DCI 0_3 belongs corresponds to the set of cells to which the cell actually scheduled by the first downlink control information belongs in a one-to-one correspondence manner, for example, in the case that the set of cells to which the cell actually scheduled by the first downlink control information indicated by the network device belongs to the MC-DCI-setofCells2, the terminal may determine the set of cells to which the cell actually scheduled by the MC-DCI 0_3 belongs according to schedule cell-listdi-0-3.

In some embodiments, such as shown in fig. 3, for MC-DCI 1_3, the network device may indicate to the terminal, via an information element schedule cell-listdi-1-3 in RRC signaling, the set of cells to which the cell actually scheduled by MC-DCI 1_3 belongs. The cell set to which the cell actually scheduled by the MC-DCI 1_3 belongs corresponds to the cell set to which the cell actually scheduled by the first downlink control information belongs in a one-to-one correspondence, for example, in the case that the cell set to which the cell actually scheduled by the first downlink control information indicated by the network device belongs to the MC-DCI-setofCells2, the terminal may determine the cell set to which the cell actually scheduled by the MC-DCI 1_3 belongs according to schedule cell-listdi-1-3.

In some embodiments, the network device may indicate to the terminal the cell combinations that the first downlink control information can schedule, e.g., for MC-DCI 0_3, as shown in fig. 3, the network device may indicate the cell combinations that the MC-DCI 0_3 can schedule, e.g., may indicate the cell combination list, by an information element schedule cell comboslitdci-0-3 under schedule cell-listdi-0-3. For example, in fig. 3, the cell combinations that can be scheduled by the MC-DCI 0_3 include ScheduledCellCombo0 to ScheduledCellCombo 15 for 16 cell combinations, and the corresponding combination indexes (indexes) are 0 to 15, respectively.

In some embodiments, the network device may indicate to the terminal the cell combination actually scheduled by the MC-DCI 0_3, which may include at least one cell. For example, the network device may indicate to the terminal that the MC-DCI 0_3 is actually scheduled cell group through the information field in the first downlink control information, e.g., the network device may indicate to the terminal that the MC-DCI 0_3 is actually scheduled cell group through the scheduling cell indication (Scheduled cells indicator) information field in the first downlink control information, where the MC-DCI 0_3 is actually scheduled cell group belonging to the cell group combination list that the MC-DCI 0_3 indicated by the scheduling cellcomboslitdci-0-3 can schedule, e.g., in fig. 3, the MC-DCI 0_3 is actually scheduled cell group indicated to the terminal through the Scheduled cells indicator is the cell group combination schedulcellcombo 1 corresponding to the index 1.

When the network device does not indicate the cell group list that can be scheduled by the first downlink control information, for example, does not configure scheduledcellcomboslitdci-0-3, the network device may indicate the cell group actually scheduled by the first downlink control information through a frequency domain resource allocation (Frequency domain resource assignment, FDRA) domain.

In some embodiments, the network device may indicate to the terminal the cell combinations that the first downlink control information can schedule, e.g., for MC-DCI 1_3, as shown in fig. 3, the network device may indicate the cell combinations that MC-DCI 1_3 can schedule by an information element scheduledcellcomboslitdci-1-3 under ScheduledCell-listdi-1-3, e.g., may indicate a cell combination list. For example, in fig. 3, the cell combinations that can be scheduled by the MC-DCI 1_3 include ScheduledCellCombo0 to ScheduledCellCombo 15, and 16 cell combinations in total, and the corresponding indexes (indexes) are 0 to 15, respectively.

In some embodiments, the network device may indicate to the terminal the cell combination actually scheduled by the MC-DCI 1_3, which may include at least one cell. For example, the network device may indicate to the terminal that the cell group actually scheduled by the MC-DCI 1_3 may be indicated by the information field in the first downlink control information, e.g., the network device may indicate to the terminal that the cell group actually scheduled by the MC-DCI 1_3 may belong to a cell group list that can be scheduled by the MC-DCI 1_3 indicated by the schedule cellcomboslitdci-1-3 by the scheduling cell indication (Scheduled cells indicator) information field in the first downlink control information, e.g., in fig. 3, the cell group actually scheduled by the MC-DCI 1_3 indicated to the terminal by Scheduled cells indicator is the cell group ScheduledCellCombo1 corresponding to the index 1.

When the network device does not indicate the cell group list that can be scheduled by the first downlink control information, for example, does not configure scheduledcellcomboslitdci-1-3, the network device may indicate the cell group actually scheduled by the first downlink control information through a Frequency Domain Resource Allocation (FDRA) domain.

In some embodiments, the cells that can be scheduled by the first downlink control information may be determined according to configuration information of the network device, or may be determined according to a predefined rule, which is not limited in this disclosure. The cell which can be scheduled by the first downlink control information is used for representing the capacity range of the first downlink control information, and the cell which is actually scheduled belongs to the cell which can be scheduled by the first downlink control information.

In some embodiments, the first downlink control information comprises at least one field (field), which may also be referred to as a field. Since the first downlink control information may be used to schedule a plurality of cells, and then the information field in the first downlink control information may be scheduled to at least one of the plurality of cells, it is necessary to determine the size (size) of the information field, that is, the number of bits occupied by the information, in order to accurately parse the information field.

In some embodiments, the information domain schedules a cell, which means that the information indicated by the information domain may enable scheduling of the terminal in the applied cell. For example, taking the information field of a channel state information (Channel State Information, CSI) Request (e.g. referred to as CSI Request), the CSI Request may indicate to the terminal in the applied cell whether the network device requests the terminal to report channel state information, i.e. whether the CSI Request is used to schedule the terminal to report channel state information in the applied cell.

In a first aspect, embodiments of the present disclosure provide an information determination method. In some embodiments, the information determining method may be performed by a terminal, and the information determining method may include the steps of:

determining a second size of a first information field in first downlink control information for scheduling the plurality of cells according to at least one of the following first sizes:

a first size of a first information field corresponding to each cell in a cell set to which the cell corresponding to the first downlink control information belongs, or

And a first size of a first information field corresponding to a first reference cell in the cell combination corresponding to the first downlink control information.

In some embodiments, the first downlink control information may include one or more information fields, wherein a portion of the information fields need not be applied to all of the cells actually scheduled by the first downlink control information, but need only be applied to a portion of the cells actually scheduled by the first downlink control information, and such information fields may be referred to as first information, which may be applied to a portion of the cells actually scheduled by the first downlink control information. That is, the first information field may be an information field applied to a part of cells among cells actually scheduled by the first downlink control information, for example, a type of the first information field may be referred to as type1C.

It should be noted that, in some embodiments, the information field is applied to a cell, which may mean that information indicated by the information field may be applied to the cell. For example, taking the channel state information Request (e.g., CSI Request) information field as an example, the information indicated by the CSI Request field is 00011, that is, indicates the value 3, meaning that the report trigger state report trigger state corresponding to the value 3 is triggered, then the CSI Request field is applied to the cell #1, and the pointer is determined to be triggered to the cell #1 corresponding to report trigger state of the value 3. The terminal can perform corresponding CSI measurement reporting in the cell #1 based on triggered trigger state configuration according to the CSI Request domain.

For example, the cells actually scheduled by the first downlink control information include 3 cells, namely, a cell #1 with an index of 1, a cell #2 with an index of 2, and a cell #3 with an index of 3, and the first information field is applied to a part of the 3 cells, for example, to the cell #1 and the cell #2, for example, to the cell #2 and the cell #3, for example, to the cell #1, for example, to the cell #2, for example, to the cell #3.

In some embodiments, the partial cells of the first information domain application comprise: the cell with the smallest index in the cells actually scheduled by the first downlink control information. That is, the first information field may be an information field applied to a cell with the smallest index among cells actually scheduled by the first downlink control information, among information fields included in the first downlink control information. For example, taking an example in which the cell actually scheduled by the first downlink control information includes a cell #1 with an index of 1, a cell #2 with an index of 2, and a cell #3 with an index of 3, the first information field may be an information field applied to the cell #1 in an information field included in the first downlink control information.

As shown in fig. 4, determining, according to a first size of a first information field corresponding to each cell in a cell set to which the cell corresponding to the first downlink control information belongs, a second size of the first information field in the first downlink control information includes:

in step S401, a second size of the first information field in the first downlink control information is determined according to a maximum value of the first size of the first information field corresponding to each cell in the cell set to which the cell corresponding to the first downlink control information belongs.

It should be noted that the embodiment shown in fig. 4 may be implemented independently or in combination with at least one other embodiment in the disclosure, and specifically may be selected as needed, which is not limited by the disclosure.

In some embodiments, the first information field includes at least one of: a channel state information Request (e.g., CSI Request) information field, and an uplink shared channel indication (e.g., UL-SCH indicator) information field.

In some embodiments, for each cell in the set of cells to which the cell corresponding to the first downlink control information belongs, the terminal may determine a first size of a first information field corresponding to the cell, for example, may determine the first size of the first information field corresponding to each cell according to a manner of determining the size of the information field in the legacy downlink control information, for example, the network device may send report trigger size (e.g., reportTriggerSize) signaling to the terminal on the cell #1, for indicating the first size of the CSI Request field corresponding to the cell # 1.

Taking the example that the first information field includes the CSI Request field, for example, the network device may indicate, for each cell, the first size of the CSI Request field through report trigger size (e.g. reportTriggerSize) signaling, and the terminal may determine, according to the report trigger size signaling sent by the network device, the first size of the CSI Request field corresponding to each cell.

Since the first downlink control information is used for scheduling a plurality of cells, each cell in the cell set to which the cell corresponding to the first downlink control information belongs indicates a first size of a first information field corresponding to the cell, and the first sizes of the first information fields corresponding to different cells may be different. It is therefore necessary to determine how to determine the size of the first information field in the first downlink control information in order to resolve the first information field accurately.

According to the embodiment of the disclosure, the terminal may determine the second size of the first information domain in the first downlink control information according to the maximum value of the first size of the first information domain corresponding to each cell in the cell set to which the cell corresponding to the first downlink control information belongs. Accordingly, for the first information domain in the first downlink control information, the second size of the information domain can be determined explicitly according to the maximum value of the first size of the first information domain corresponding to each cell in the cell set, so as to accurately analyze the first information domain according to the second size. In order to avoid the problem caused by that in the case that the first downlink control information schedules the plurality of cells, the second size of the first information field in the first control information is not explicitly determined according to the first size of the first information field corresponding to which cell of the plurality of cells.

In some embodiments, the second size of the first information field in the first downlink control information is equal to a maximum value.

a cell set to which a cell to which the first downlink control information can be scheduled belongs;

the set of cells to which the cell actually scheduled by the first downlink control information belongs may also be referred to as a set of cells to which the cell scheduled by the first downlink control information belongs.

For example, taking an example that the cell set to which the cell corresponding to the first downlink control information belongs includes the cell set to which the cell capable of being scheduled by the first downlink control information belongs, for example, the cell set to which the cell capable of being scheduled by the first downlink control information belongs is {1,2,3,4}, that is, includes the cell #1 with the index of 1, the cell #2 with the index of 2, the cell #3 with the index of 3, and the cell #4 with the index of 4.

For example, the first size of the first information field corresponding to cell #1 is 2, i.e., 2 bits; the first size of the first information field corresponding to cell #2 is 3, i.e., 3 bits; the first size of the first information field corresponding to cell #3 is 4, i.e., 4 bits; the first size of the first information field corresponding to cell #4 is 5, i.e., 5 bits. The maximum value of the first size of the first information domain corresponding to each cell in the cell set is 5, so that the terminal can determine that the first information domain occupies 5 bits in the first downlink control information.

For example, taking an example that the cell set to which the cell corresponding to the first downlink control information belongs includes the cell set to which the cell actually scheduled by the first downlink control information belongs, for example, the cell set to which the cell actually scheduled by the first downlink control information belongs is {1,2,3}, that is, includes the cell #1 with the index of 1, the cell #2 with the index of 2, and the cell #3 with the index of 3.

For example, the first size of the first information field corresponding to cell #1 is 2, i.e., 2 bits; the first size of the first information field corresponding to cell #2 is 3, i.e., 3 bits; the first size of the first information field corresponding to cell #3 is 4, i.e., 4 bits. The maximum value of the first size of the first information field corresponding to each cell in the cell set is 4, so the terminal can determine that the second size of the first information field in the first downlink control information is 4.

The manner in which the second size of the first information field in the first downlink control information is determined is exemplified by several embodiments below.

Taking the example that the first information field includes a CSI Request information field, the second size of the CSI Request information field in the first downlink control information is equal toWherein (1)>Refers to the number of cells in a cell set to which a cell actually scheduled by first downlink control information belongs, wherein r is mapped one by one based on the order of the cell indexes from small to large, and r=1 corresponds to the cell with the smallest index in the cell set, and M _c (r) represents a first size of a first information field corresponding to an r-th cell in the set of cells. Wherein M is _c (r) may be determined based on higher layer parameters, e.g. based on a reporting trigger size (e.g. reportTriggerSize), e.g. the first size may range from 0 to 6.

Taking the example that the first information field includes an UL-SCH indicator information field, the second size of the UL-SCH indicator information field in the first downlink control information is equal toWherein (1)>Refers to the number of cells in a cell set to which a cell actually scheduled by first downlink control information belongs, wherein r is mapped one by one based on the order of the cell indexes from small to large, and r=1 corresponds to the cell with the smallest index in the cell set, and M _c (r) represents a first size of a first information field corresponding to an r-th cell in the set of cells. Wherein M is when the number of scheduled PUSCHs indicated by the time domain resource allocation (Time Domain Resource Assignment, TDRA) domain is 1 _c (r) a first dimension of 0, otherwise M _c The first dimension of (r) is 1. At M _c When the first size of (r) is 1, if the 1 bit value is 1, the corresponding UL-SCH is transmitted on PUSCH, and if the 1 bit value is 0, the corresponding UL-SCH is not transmitted on PUSCH.

In some embodiments, the value of the CSI Request information field in the first downlink control information is 0, and the value of the UL-SCH indicator information field is 0. The terminal may not expect to receive such first downlink control information, i.e., the terminal does not expect to receive the first downlink control information having a value of 0 for the CSI Request information field and a value of 0 for the UL-SCH indicator information field.

In some embodiments, determining the second size of the first information field in the first downlink control information according to the first size of the first information field corresponding to the first reference cell in the cell combination corresponding to the first downlink control information includes:

the terminal is configured with a first signaling, and determines a second size of a first information domain in the first downlink control information according to a first size of the first information domain corresponding to a first reference cell in a cell combination corresponding to the first downlink control information; the first signaling is used for indicating the cell combination corresponding to the first downlink control information.

In some embodiments, the information determining method further comprises: the terminal is not configured with a first signaling, and determines a second size of the first information domain in the first downlink control information according to a maximum value of the first size of the first information domain corresponding to each cell in the cell set to which the cell corresponding to the first downlink control information belongs.

In some embodiments, the network device may configure a first signaling for the terminal, where the first signaling is used to indicate a cell combination corresponding to the first downlink control information.

In the case that the terminal is configured with the first signaling, the terminal may determine a cell group corresponding to the first downlink control information, and then the terminal may determine a first reference cell in the cell group; the second size of the first information field in the first downlink control information is determined according to the first reference cell, for example, the second size may be determined to be equal to the size of the first information field corresponding to the first reference cell.

If the terminal is not configured with the first signaling, the terminal cannot determine the cell group corresponding to the first downlink control information, and then the terminal can determine the maximum value of the first size of the first information domain corresponding to each cell in the cell set to which the cell corresponding to the first downlink control information belongs, and determine the second size of the first information domain in the first downlink control information according to the maximum value.

cell combinations that can be scheduled by the first downlink control information;

For example, the first signaling includes at least one of:

ScheduledCellCombo-ListDCI-0-3；

ScheduledCellCombo-ListDCI-1-3。

in some embodiments, the first reference cell comprises at least one of:

the cell with the smallest cell index in the cell group;

the cell with the largest cell index in the cell group;

and the corresponding cell with the largest size of the first information field in the cell combination.

In some embodiments, the terminal may determine a cell group corresponding to the first downlink control information, and then the terminal may determine a first reference cell in the cell group; and determining a second size of the first information field in the first downlink control information according to the first reference cell.

the first reference cell is a cell with the minimum cell index in the cell group.

A possible implementation manner, the terminal is based on a specific information domain of the first downlink control information, for example: scheduled cells indicator domain or Frequency domain resource assignment domain, and determining the cell actually scheduled by the first downlink control information. And determining that the second size of the first information field in the first downlink control information is equal to the first size of the first information field corresponding to the cell with the smallest cell index value in the actually scheduled cells.

In some embodiments, taking as an example that the first information field comprises a CSI request field. The actually scheduled cell may be indicated by Scheduled cells indicator or Frequency domain resource assignment fields, and the size of the CSI request field may be determined according to the reportTriggerSize of the cell with the smallest index (e.g., serving cell index) among the actually scheduled cells, e.g., the CSI request field may be 0,1,2,3,4,5, or 6 bits in size. The CSI request field is applied to the cell with the smallest index.

In some embodiments, the first information field includes an UL-SCH indicator field. The number of bits occupied by the size of the UL-SCH indicator field is M _U (r), where r refers to the cell with the smallest index (e.g., serving cell index) among the actually scheduled cells indicated by the Scheduled cells indicator or Frequency domain resource assignment domain. Wherein M is _U (r) can be determined by:

when the number of actually scheduled PUSCHs indicated by Time domain resource assignment field is greater than 1, m _U (r) is 0 bit.

Otherwise, M _U (r) is 1 bit. Wherein when the value is 1, it is used for indicating that the UL-SCH should be transmitted on the PUSCH, and when the value is 0, it is used for indicating that the UL-SCH should not be transmitted on the PUSCH. When the terminal does not support triggering SRS only in DCI (Sounding Reference Signal ), the terminal does not expect to receive DCI format 0_1 when the UL-SCH indicator field indicates 0 and the CSI request field is all 0, unless CRC (Cyclic Redundancy Check ) of DCI format 0_1 is preempted by SP-CSI-RNTI (semi-permanent channel state information radio network temporary identity). When the terminal supports triggering SRS only in DCI, the terminal does not expect to indicate 0 in the UL-SCH indicator domain, the CSI request domain is all 0, and the SRS request domain is all 0 to receive DCI format 0_1 unless CRC of DCI format 0_1 is preempted by SP-CSI-RNTI.

Wherein RNTI is generally known as Radio Network Temporary Indentifier, SP is generally known as Semi-Persistent.

For example, the cell combinations corresponding to the first downlink control information may include one or more cell combinations. For example, the cells included in the cell group corresponding to the first downlink control information are shown in table 1:

cell group	Cells included in a cell combination
		Cell combination #1	Cell #1, cell #2
Cell group #2	Cell #2, cell #4

TABLE 1

As shown in table 1, taking an example that the cell group corresponding to the first downlink control information includes 2 small combinations, which are cell combination #1 and cell combination #2, respectively, wherein cell combination #1 includes cell #1 and cell #2, and cell combination #2 includes cell #2 and cell #4.

When the first reference cell includes a cell with the smallest cell index in the cell group, it may be determined that the cell with the smallest cell index in the two cell groups is cell #1. Further, it may be determined that the second size of the first information field in the first downlink control information is the size of the first information field corresponding to the cell #1, for example, the second size is 2.

When the first reference cell includes a cell with the largest cell index in the cell group, it may be determined that the cell with the largest cell index in the two cell groups is cell #4. Further, it may be determined that the second size of the first information field in the first downlink control information is the size of the first information field corresponding to the cell #4, for example, the second size is 5.

When the first reference cell includes a cell having the largest size of the first information field corresponding to the cell combination, based on the previous example, the size of the first information field corresponding to the cell #1 is 2, the size of the first information field corresponding to the cell #2 is 3, and the size of the first information field corresponding to the cell #4 is 5, it is thus possible to determine that the size of the first information field corresponding to the cell #4 is largest, thereby determining that the first reference cell is the cell #4. Further, it may be determined that the second size of the first information field in the first downlink control information is the size of the first information field corresponding to the cell #4, for example, the second size is 5.

In some embodiments, the information determining method further comprises: and when the second size of the first information domain is larger than the third size of the first information domain corresponding to the first cell actually applied by the first information domain, analyzing the first information domain according to the first number of bits in the bits occupied by the first information domain so as to determine information indicated by the first information domain to the first cell.

In some embodiments, the first size of the first information domain in the first downlink control information may be greater than the third size of the first information domain corresponding to the first cell to which the first information domain is actually applied. In this case, the terminal may parse the first information domain according to a first number of bits in the bits occupied by the first information domain, so as to ensure that the parsed information can be smoothly applied to the first cell, and implement an indication function of the first information domain on the first cell.

In some embodiments, the first number is equal to the third size.

For example, in the first downlink control information, the first size of the first information field is 5, the third size of the first information field corresponding to the first cell actually applied by the first information field is 4, and the first size is greater than the third size, then 4 bits may be determined from 5 bits of the first information field, and the 4 bits are further analyzed to obtain information indicated by the first information field to the first cell.

the first number of most significant bits in the bits occupied by the first information field, that is, the first number of bits starting from the most significant bits in the bits occupied by the first information field;

the first number of least significant bits of the bits occupied by the first information field, i.e. the first number of bits starting from the least significant bits of the bits occupied by the first information field.

For example, in the first downlink control information, the first size of the first information field is 5, the indication value is 10011, the third size of the first information field corresponding to the first cell actually applied by the first information field is 4, and the first size is greater than the third size, then the 4 bit values corresponding to the most significant bit may be determined from the 5 bits of the first information field, that is, the analysis 1001 may be performed, and the analysis result may be used as information indicated by the first information field to the first cell.

For example, in the first downlink control information, the first size of the first information field is 5, the indication value is 10011, the third size of the first information field corresponding to the first cell actually applied by the first information field is 4, and the first size is greater than the third size, then the 4 bit values corresponding to the least significant bits may be determined from the 5 bits of the first information field, that is, the analysis 0011 may be performed, and the analysis result may be used as information indicated by the first information field to the first cell.

In some embodiments, the information determining method further comprises: and when the second size of the first information field is smaller than the third size of the first information field corresponding to the first cell to which the first information field is actually applied, analyzing the first information field by adding a second number of bits with zero value to the first information field so as to determine information indicated by the first information field to the first cell.

In some embodiments, the first size of the first information field in the first downlink control information may be smaller than the third size of the first information field corresponding to the first cell to which the first information field is actually applied. In this case, the terminal may parse the first information domain by adding a second number of bits with a value of zero to the first information domain, so as to ensure that the parsed information can be smoothly applied to the first cell, and implement an indication function of the first information domain to the first cell.

For example, in the first downlink control information, the first size of the first information field is 5, the third size of the first information field corresponding to the first cell actually applied by the first information field is 6, the first size is smaller than the third size, and the difference between the third size and the first size is 1, so that the first information field can be analyzed according to a bit mode of adding 1 to 5 bits of the first information field and adding 0 to obtain information indicated by the first information field to the first cell.

In some embodiments, adding a second number of zero valued bits to the first information field includes at least one of:

adding a zero-valued bit before the most significant bit of the first information field;

the least significant bit of the first information field is followed by a bit of zero value.

For example, in the first downlink control information, the first size of the first information field is 5, specifically 10011, the third size of the first information field corresponding to the first cell actually applied by the first information field is 6, and the first size is smaller than the third size, and then the bit with the value 0 may be added before the most significant bit of the 5 bits of the first information field. For example, 010011 is obtained after adding a bit having a value of 0 to the first information field, and 010011 can be parsed, and the result of the parsing can be used as information indicated by the first information field to the first cell.

For example, in the first downlink control information, the first size of the first information field is 5, specifically 10011, the third size of the first information field corresponding to the first cell actually applied by the first information field is 6, and the first size is smaller than the third size, and then the least significant bit of the 5 bits of the first information field may be added with a bit having a value of 0. For example, if the bit having the value 0 is added to the first information field, 100110 is obtained, and the analysis result is analyzed 100110 as the information indicated by the first information field to the first cell.

In a second aspect, embodiments of the present disclosure provide an information determination method. Fig. 5 is a schematic flow chart diagram illustrating a method of information determination according to an embodiment of the present disclosure. The information determination method shown in the present embodiment may be performed by a terminal.

As shown in fig. 5, the information transmission method may include the steps of:

in step S501, the size of a first information field in first downlink control information for scheduling a plurality of cells is determined according to a first configuration signaling.

It should be noted that the embodiment shown in fig. 5 may be implemented independently or in combination with at least one other embodiment in the disclosure, and specifically may be selected as needed, which is not limited by the disclosure.

In some embodiments, for each cell in the set of cells to which the cell corresponding to the first downlink control information belongs, the terminal may determine the first size of the first information domain corresponding to the cell, for example, may determine the first size of the first information domain corresponding to each cell according to a manner of determining the size of the information domain in the conventional downlink control information.

For example, the first configuration signaling may be determined based on the reference cell, for example, the first size of the first information field in the first downlink control information indicated by the first configuration signaling may be determined specifically according to the size of the first information field corresponding to the reference cell.

Taking the example that the first downlink control information includes DCI 0_3, the first information field includes a CSI Request information field.

In some embodiments, the size of the CSI Request information field may be determined based on higher layer parameters in the reference cell. For example, based on a report trigger size (e.g., reporttriggersizeddci-0-3), the size of the CSI Request information field may range from 0 to 6, for example.

Taking the example that the first downlink control information includes DCI 0_3 and the first information field includes an UL-SCH indicator information field.

In some embodiments, the size of the UL-SCH indicator information field may be determined based on higher layer parameters in the reference cell. For example, based on the uplink shared channel downlink control information (e.g., UL-SCHDCI-0-3), if UL-SCHDCI-0-3 is not enabled (enabled), or disabled (disabled), or the indicated value is 0/1, the size of the UL-SCH indicator information field is 0, and if UL-SCHDCI-0-3 is enabled (enabled), or the indicated value is 1/0, the size of the UL-SCH indicator information field is 1.

In some embodiments, the reference cell comprises at least one of:

scheduling cells (cells where the terminal receives the first downlink control information);

the method comprises the steps that a cell with the largest size of a corresponding first information domain in a cell set to which a cell corresponding to first downlink control information belongs;

a cell for calculating a size of the first downlink control information;

a cell for calculating blind detection resources of the first downlink control information, e.g. the blind detection resources comprise at least one of: BD. CCE, where BD denotes Blind Detection (Blind Detection), CCE denotes a cell of a control channel element (Control Channel Element)).

Cell combinations actually scheduled by the first downlink control information;

and/or

The cell set to which the cell corresponding to the first downlink control information belongs includes at least one of the following:

the first downlink control information is a set of cells to which the actually scheduled cell belongs.

In some embodiments, the information determining method further comprises: and ignoring the conventional configuration signaling, wherein the conventional configuration signaling is used for indicating the size of the first information domain in the conventional downlink control information.

In the case where a first configuration signaling (which may be referred to as, for example, reportTriggerSizeDCI-0-3, but is not limited to reportTriggerSizeDCI-0-3) for the first downlink control information is configured to the terminal, the terminal may ignore the legacy configuration signaling, for example, reportTriggerSize.

For example, in the cell set to which the cell corresponding to the first downlink control information belongs, configuration signaling for legacy downlink control information (legacy DCI) in each cell may be omitted, where the DCI is only used for scheduling one cell.

Taking the example that the first information field includes a CSI request information field, the size of the CSI request information field is determined based on the first configuration signaling reportTriggerSize-MC-DCI, and then, for the size of the CSI request corresponding to a certain cell in the actually scheduled cell, the size may be determined based on the first configuration signaling reportTriggerSize-MC-DCI.

And the size of the CSI request corresponding to each cell is not required to be determined based on the configuration signaling reportTriggerSize for legacy DCI in each cell in the cell set to which the cell corresponding to the first downlink control information belongs. Wherein, for example, the network device does not configure the configuration signaling reportTriggerSize for legacy DCI in each cell, or, for example, the network device configures the configuration signaling reportTriggerSize for legacy DCI in cell #1, but the terminal does not parse the signaling, or, for example, the network device configures the configuration signaling reportTriggerSize for legacy DCI in cell #1, the terminal may parse the signaling, but the size of CSI request corresponding to cell #1 is not determined based on the parsing result.

In some embodiments, the set of cells to which the cell corresponding to the first downlink control information belongs includes at least one of: a cell set to which a cell to which the first downlink control information can be scheduled belongs; the first downlink control information is a set of cells to which the actually scheduled cell belongs.

In some embodiments, the first configuration signaling is based on a cell set configuration. That is, the terminal may determine the size of the corresponding first information field in the first downlink information according to the first configuration signaling. And/or, the terminal may determine, according to the first configuration signaling, analysis information of the first information domain corresponding to each cell in the cell set to which the cell corresponding to the first downlink control information belongs. For example, the terminal determines that the first size of the first information field corresponding to each cell is determined based on the first configuration signaling, so as to determine an indicated value of the first information field in the first downlink control information, that is, an indicated value of each cell in the actually scheduled cell. For example, the cell set to which the cell corresponding to the first downlink control information belongs includes cell #1, cell #2, cell #3 and cell #4, and the terminal receives the first configuration signaling reportTriggerSizeDCI-0-3, for example, based on receiving the first configuration signaling by one cell in the cell set, the size of the CSI request information field corresponding to each cell in the 4 cells may be determined according to the reportTriggerSizeDCI-0-3, so as to determine the parsing manner corresponding to the CSI request information field in each cell. Therefore, according to this embodiment, the terminal ignores the configuration signaling for legacy DCI in each cell in the cell set to which the cell corresponding to the first downlink control information belongs, and can still determine the size of the information field corresponding to each cell in the cell set to which the cell corresponding to the first downlink control information belongs according to the first configuration signaling.

In a third aspect, embodiments of the present disclosure provide an information determination method. In some embodiments, the information determination method may be performed by a network device, and the information determination method may include the steps of:

It should be noted that, in some embodiments, the information field is applied to a cell, which may mean that information indicated by the information field may be applied to the cell. For example, taking the channel state information Request (e.g. CSI Request) information field as an example, the information indicated by the CSI Request field is 00011, that is, indicates a value of 3, meaning that 3 CSI are requested to be reported, and then the CSI Request field is applied to the cell #1, which indicates that 3 CSI are requested to be reported to the cell # 1. The terminal may determine 3 CSI by measuring a reference signal in cell #1 according to the CSI Request field and transmit the 3 CSI to the network device.

In some embodiments, determining, according to a first size of a first information field corresponding to each cell in a set of cells to which the cell corresponding to the first downlink control information belongs, a second size of the first information field in the first downlink control information includes:

and determining a second size of the first information domain in the first downlink control information according to a first size of the first information domain corresponding to the application cell in the cell set to which the cell corresponding to the first downlink control information belongs, wherein the application cell is the cell with the minimum index in the cells actually scheduled by the first downlink control information.

As shown in fig. 6, determining, according to a first size of a first information field corresponding to each cell in a cell set to which the cell corresponding to the first downlink control information belongs, a second size of the first information field in the first downlink control information includes:

in step S601, a second size of the first information field in the first downlink control information is determined according to a maximum value of the first size of the first information field corresponding to each cell in the cell set to which the cell corresponding to the first downlink control information belongs.

In some embodiments, for each cell in the set of cells to which the cell corresponding to the first downlink control information belongs, the network device may determine a first size of a first information field corresponding to the cell, e.g., may determine the first size of the first information field corresponding to each cell according to a manner of determining the size of the information field in the legacy downlink control information, e.g., the network device may send report trigger size (e.g., reportTriggerSize) signaling to the terminal on the cell #1, for indicating the first size of the CSI Request field corresponding to the cell # 1.

According to the embodiment of the disclosure, the network device may determine the second size of the first information domain in the first downlink control information according to the maximum value of the first size of the first information domain corresponding to each cell in the cell set to which the cell corresponding to the first downlink control information belongs. Accordingly, for the first information domain in the first downlink control information, the second size of the information domain can be determined explicitly according to the maximum value of the first size of the first information domain corresponding to each cell in the cell set, so as to accurately analyze the first information domain according to the second size. In the case that the first downlink control information schedules the plurality of cells, the problem caused by determining the second size of the first information field in the first control information according to the first size of the first information field corresponding to which cell of the plurality of cells is not sure is avoided.

For example, the first size of the first information field corresponding to cell #1 is 2, i.e., 2 bits; the first size of the first information field corresponding to cell #2 is 3, i.e., 3 bits; the first size of the first information field corresponding to cell #3 is 4, i.e., 4 bits; the first size of the first information field corresponding to cell #4 is 5, i.e., 5 bits. The maximum value of the first size of the first information domain corresponding to each cell in the cell set is 5, so the network device can determine that the first information domain occupies 5 bits in the first downlink control information.

For example, the first size of the first information field corresponding to cell #1 is 2, i.e., 2 bits; the first size of the first information field corresponding to cell #2 is 3, i.e., 3 bits; the first size of the first information field corresponding to cell #3 is 4, i.e., 4 bits. The maximum value of the first size of the first information field corresponding to each cell in the cell set is 4, so the network device may determine that the second size of the first information field in the first downlink control information is 4.

In some embodiments, the value of the CSI Request information field in the first downlink control information is 0, and the value of the UL-SCH indicator information field is 0. The network device may not transmit such first downlink control information, i.e., the first downlink control information having a value of 0 for the CSI Request information field and a value of 0 for the UL-SCH indicator information field. The terminal may not expect to receive such first downlink control information, i.e., it does not expect to receive the first downlink control information having the value of 0 of the CSI Request information field and the value of 0 of the UL-SCH indicator information field.

a first signaling is configured for the terminal, and a second size of a first information domain in the first downlink control information is determined according to a first size of the first information domain corresponding to a first reference cell in a cell combination corresponding to the first downlink control information; the first signaling is used for indicating the cell combination corresponding to the first downlink control information.

In some embodiments, the information determining method further comprises: and determining a second size of the first information domain in the first downlink control information according to the maximum value of the first size of the first information domain corresponding to each cell in the cell set to which the cell corresponding to the first downlink control information belongs.

In the case that the terminal is not configured with the first signaling, the network device may determine a cell group corresponding to the first downlink control information, and then the network device may determine a first reference cell in the cell group; the second size of the first information field in the first downlink control information is determined according to the first reference cell, for example, the second size may be determined to be equal to the size of the first information field corresponding to the first reference cell.

If the first signaling is not configured for the terminal, the network device does not determine the cell group corresponding to the first downlink control information yet, and then the network device may determine, in the cell set to which the cell corresponding to the first downlink control information belongs, a maximum value of a first size of the first information domain corresponding to each cell, and determine, according to the maximum value, a second size of the first information domain in the first downlink control information.

For example, the first signaling includes at least one of:

ScheduledCellCombo-ListDCI-0-3；

ScheduledCellCombo-ListDCI-1-3。

in some embodiments, the first reference cell comprises at least one of:

the cell with the smallest cell index in the cell group;

the cell with the largest cell index in the cell group;

For example, the cell combinations corresponding to the first downlink control information may include one or more cell combinations. For example, the cell combinations corresponding to the first downlink control information may include cells as shown in table 1 above.

In some embodiments, the information determining method further comprises: and when the second size of the first information field is larger than the third size of the first information field corresponding to the first cell actually applied by the first information field, determining information indicated by the first information field to the first cell according to a first number of bits in the bits occupied by the first information field.

In some embodiments, the first size of the first information domain in the first downlink control information may be greater than the third size of the first information domain corresponding to the first cell to which the first information domain is actually applied. In this case, the network device may determine, according to a first number of bits in the bits occupied by the first information domain, information indicated by the first information domain to the first cell, so as to ensure that the information indicated by the first information domain can be smoothly applied to the first cell, and implement an indication function of the first information domain to the first cell.

In some embodiments, the first number is equal to the third size.

For example, in the first downlink control information, the first size of the first information field is 5, the third size of the first information field corresponding to the first cell to which the first information field is actually applied is 4, and the first size is greater than the third size, then the network device may determine 4 bits from the 5 bits of the first information field, and further may determine information indicated by the first information field to the first cell according to the 4 bits.

For example, in the first downlink control information, the first size of the first information field is 5, the indication value is 10011, the third size of the first information field corresponding to the first cell actually applied by the first information field is 4, and the first size is greater than the third size, then the 4 bit values corresponding to the most significant bits may be determined in the 5 bits of the first information field, that is, 1001, the network device may determine, according to 1001, information indicated by the first information field to the first cell.

For example, in the first downlink control information, the first size of the first information field is 5, the indication value is 10011, the third size of the first information field corresponding to the first cell actually applied by the first information field is 4, and the first size is greater than the third size, then the 4 bit values corresponding to the least significant bits may be determined in the 5 bits of the first information field, that is, 0011, and the network device may determine, according to 0011, information indicated by the first information field to the first cell.

In some embodiments, the information determining method further comprises: and when the second size of the first information field is smaller than the third size of the first information field corresponding to the first cell actually applied by the first information field, determining information indicated by the first information field to the first cell by adding a second number of bits with zero value to the first information field.

In some embodiments, the first size of the first information field in the first downlink control information may be smaller than the third size of the first information field corresponding to the first cell to which the first information field is actually applied. In this case, the network device may determine the information indicated by the first information domain to the first cell by adding a second number of bits with a value of zero to the first information domain, so as to ensure that the information indicated by the first information domain can be smoothly applied to the first cell, and implement the indication function of the first information domain to the first cell.

For example, in the first downlink control information, the first size of the first information field is 5, the third size of the first information field corresponding to the first cell actually applied by the first information field is 6, the first size is smaller than the third size, and the difference between the third size and the first size is 1, so that the information indicated by the first information field for the first cell may be determined in a manner of adding 1 bit to 5 bits of the first information field and adding 0 value to the first bit.

increasing a second number of bits of zero value before the most significant bit of the first information field;

a second number of bits with a value of zero is added after the least significant bit of the first information field.

For example, in the first downlink control information, the first size of the first information field is 5, specifically 10011, the third size of the first information field corresponding to the first cell actually applied by the first information field is 6, and the first size is smaller than the third size, and then the bit with the value 0 may be added before the most significant bit of the 5 bits of the first information field. For example, 010011 is obtained after adding a bit with a value of 0 to the first information field, and then information indicated by the first information field to the first cell can be determined according to 010011.

For example, in the first downlink control information, the first size of the first information field is 5, specifically 10011, the third size of the first information field corresponding to the first cell actually applied by the first information field is 6, and the first size is smaller than the third size, and then the least significant bit of the 5 bits of the first information field may be added with a bit having a value of 0. For example, the bit added to the first information field by 0 is obtained 100110, and then the information indicated by the first information field to the first cell can be determined according to 100110.

In a fourth aspect, embodiments of the present disclosure provide an information determination method. Fig. 7 is a schematic flow chart diagram illustrating a method of information determination according to an embodiment of the present disclosure. The information determination method shown in the present embodiment may be performed by a terminal.

As shown in fig. 7, the information transmission method may include the steps of:

in step S701, configuration signaling is sent to the terminal, where the configuration signaling is used by the terminal to determine a size of a first information field in first downlink control information for scheduling a plurality of cells.

It should be noted that the embodiment shown in fig. 7 may be implemented independently or in combination with at least one other embodiment in the disclosure, and specifically may be selected as needed, which is not limited by the disclosure.

In some embodiments, the configuration signaling is sent to the terminal at the reference cell.

In some embodiments, the size of the UL-SCH indicator information field may be determined based on higher layer parameters in the reference cell. For example, based on the uplink shared channel downlink control information (e.g., UL-SCHDCI-0-3), it is determined that if UL-SCHDCI-0-3 is not enabled (enabled), or disabled, or the indication value is 0/1, the size of the UL-SCH indicator information field is 0, if UL-SCHDCI is enabled (enabled), or the indication value is 1/0, and the size of the UL-SCH indicator information field is 1.

In some embodiments, the reference cell comprises at least one of:

scheduling cells;

a cell for calculating a size of the first downlink control information;

cell combinations actually scheduled by the first downlink control information;

And/or

In some embodiments, the network device may perform legacy configuration signaling to the terminal in cell #1, where the legacy configuration signaling is used to indicate the size of the first information field in the legacy downlink control information. The terminal does not parse the signaling, or the terminal may parse the signaling, but does not determine the size of the first information field corresponding to the cell #1 based on the parsing result, but determines the size of the first information field corresponding to the cell #1 according to the first configuration signaling.

For example, the network device configures the configuration signaling reportTriggerSize for legacy DCI in cell #1, but the terminal does not parse the signaling, or for example, the network device configures the configuration signaling reportTriggerSize for legacy DCI in cell #1, the terminal may parse the signaling, but does not determine the size of CSI request corresponding to cell #1 based on the parsing result.

In some embodiments, the network device may indicate, through the first configuration signaling, a size of an information domain corresponding to each cell in a set of cells to which the cell corresponding to the first downlink control information belongs. For example, the cell set to which the cell corresponding to the first downlink control information belongs includes cell #1, cell #2, cell #3 and cell #4, and the network device may send a first configuration signaling reportTriggerSize-MC-DCI to the terminal, where the reportTriggerSize-MC-DCI may indicate the size of the CSI request information field corresponding to each cell in the 4 cells. Therefore, according to this embodiment, the network device does not send configuration signaling for legacy DCI in each cell in the cell set to which the cell corresponding to the first downlink control information belongs to the terminal, and can still indicate, through the first configuration signaling, the size of the information field corresponding to each cell in the cell set to which the cell corresponding to the first downlink control information belongs.
