[0172] It should be noted that, in some embodiments, the network device may send the first downlink control information to the terminal before the terminal determines support for the first information field. Alternatively, in some embodiments, the network device may send the first downlink control information to the terminal after the terminal determines support for the first information field.

[0173] In some embodiments, the first information includes 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.

[0174] In some embodiments, the first information includes a first size of a first information field corresponding to a first reference cell in a cell combination corresponding to the first downlink control information.

[0175] In some embodiments, the terminal determines the second size of the first information field in the first downlink control information according to the 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.

[0181] In some embodiments, when the terminal is not configured with the first signaling, it can determine the second size of the first information field in the first downlink control information based on the 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.

[0182] In some embodiments, the first signaling is used to indicate a cell combination corresponding to the first downlink control information.

[0190] In some embodiments, the first information field is applied to some cells among the cells actually scheduled by the first downlink control information.

[0191] In some embodiments, the part of cells to which the first information field is applied includes: the cell with the smallest index among the cells actually scheduled by the first downlink control information.

[0192] In some embodiments, 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 to which the first information field is actually applied, the terminal parses the first information field based on a first number of bits in a proportion of the first information field. In some embodiments, the terminal may determine, based on the parsing result, the information indicated by the first information field for the first cell.

[0193] In some embodiments, the first number of bits in the proportion of the first information field includes at least one of the following:

[0194] a first number of most significant bits in the proportion of the first information field;

[0195] The first information field accounts for a first number of least significant bits in the bit.

[0196] In some embodiments, the first number is equal to the third size.

[0197] In some embodiments, 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, the terminal may parse the first information field by adding a second number of zero bits to the first information field. In some embodiments, the terminal may determine, based on the parsing result, the information indicated by the first information field for the first cell.

[0198] In some embodiments, adding a second number of zero bits to the first information field comprises at least one of the following:

[0199] adding a second number of bits having a value of zero before the most significant bit of the first information field;

[0200] A second number of bits having a value of zero are added after the least significant bit of the first information field.

[0201] In some embodiments, the second number is equal to the difference between the third size and the second size.

[0202] Step S202: The network device determines the size of the information field according to the first information.

[0203] In some embodiments, when the network device determines that the first signaling is configured for the terminal, it can determine the second size of the first information field in the first downlink control information based on 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.

[0204] In some embodiments, when the network device determines that the first signaling is not configured for the terminal, the network device determines the second size of the first information field in the first downlink control information based on the 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.

[0205] In some embodiments, 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 to which the first information field is actually applied, the network device can determine the information indicated by the first information field to the first cell based on the first number of bits in the proportion of the first information field.

[0206] In some embodiments, 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, the network device may determine the information indicated by the first information field to the first cell by adding a second number of bits with a value of zero to the first information field.

[0211] FIG2B is an interactive schematic diagram illustrating an information determination method according to an embodiment of the present disclosure.

[0212] As shown in FIG2B , the information determination method includes:

[0213] Step S203: The network device sends first information to the terminal.

[0214] In some embodiments, the first information includes first configuration signaling.

[0215] In some embodiments, the first configuration signaling is used by the terminal to determine the size of the first information field.

[0216] In some embodiments, the first information field is the first information field in first downlink control information used to schedule multiple cells.

[0217] In some embodiments, the first configuration signaling is sent to the terminal in a reference cell.

[0218] Step S204: The terminal determines the size of the first information field according to the first information.

[0235] In some embodiments, the terminal ignores legacy configuration signaling.

[0236] In some embodiments, the conventional configuration signaling is used to indicate the size of the first information field in conventional downlink control information.

[0237] The communication method involved in the embodiment of the present disclosure may include at least one of steps S203 to S204. For example, step S203 may be implemented as an independent embodiment, step S204 may be implemented as an independent embodiment, and steps S203+S204 may be implemented as independent embodiments, but are not limited thereto.

[0238] In some embodiments, steps S203 and S204 may be executed in an interchanged order or simultaneously.

[0239] In some embodiments, step S203 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0240] In some embodiments, step S204 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0241] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2A and FIG. 2B .

[0242] In some embodiments, the network device may send first downlink control information for scheduling multiple cells to the terminal. The first downlink control information may be called MC-DCI, for example, and its full name may be Multi-cell Downlink Control Information or Multi-cell scheduling Downlink Control Information.

[0243] In some embodiments, the first downlink control information is used to schedule multiple cells, and may refer to data used for the first downlink control information to schedule multiple cells, such as scheduling the physical uplink shared channel (PUSCH) and physical downlink shared channel (PDSCH) of one or more cells in the multiple cells, thereby realizing scheduling of multiple cells through one downlink control information.

[0244] In one embodiment, the terminal may receive the first downlink control information in a scheduling cell. The cell scheduled by the first downlink control information may be referred to as an actually scheduled cell. The actually scheduled cell is all or part of the cells that can be scheduled by the first downlink control information.

[0245] The following uses several embodiments to illustrate the cells that can be scheduled by the first downlink control information and the cells that are actually scheduled in this application.

[0246] FIG3 shows a schematic diagram of cells that can be scheduled by first downlink control information and cells that are actually scheduled according to an embodiment of the present disclosure.

[0247] In some embodiments, as shown in FIG3 , the network device may send Radio Resource Control (RRC) signaling to the terminal, and configure, through the RRC signaling, for the terminal a first list of cell sets to which cells that can be scheduled by the first downlink control information belong, for example, by indicating the first list through the Information Element (IE) MC-DCI-SetofCellsToAddModList in the RRC signaling. The first list may include multiple cell sets, and different sets do not include the same cell.

[0248] In some embodiments, different cell sets in the first list may include different cells. For example, if cell set #1 in the first list includes cell #1, then other cell sets in the first list will not include cell #1.

[0249] In some embodiments, as shown in Figure 3, the network device may indicate the 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 through the information element DCI field Scheduled cell set indicator in the RRC signaling. For example, the first list contains 4 sets, and for example, the 4 sets are represented by the following 4 information elements: MC-DCI-setofCells0, MC-DCI-setofCells1, MC-DCI-setofCells2, and MC-DCI-setofCells3. For example, if the set indicated by the network device in the first list is MC-DCI-setofCells2, then the terminal may determine that the set is the set of cells to which the cell actually scheduled by the first downlink control information belongs.

[0250] In some embodiments, the first downlink control information can be further divided into first downlink control information for scheduling PUSCH, for example, MC-DCI 0_3, and first downlink control information for scheduling PDSCH, for example, MC-DCI 1_3. MC-DCI 0_3 and MC-DCI 0_3 refer to MC-DCI formats, which can be downlink control information formats newly added based on legacy downlink control information formats. Legacy downlink control information can refer to downlink control information used to schedule a single cell.

[0251] In some embodiments, for example, as shown in FIG3 , for MC-DCI 0_3, the network device may indicate to the terminal the cell set to which the cell actually scheduled by MC-DCI 0_3 belongs through the information element ScheduledCell-ListDCI-0-3 in the RRC signaling. The cell set to which the cell actually scheduled by MC-DCI 0_3 belongs corresponds to the cell set to which the cell actually scheduled by the first downlink control information belongs. For example, when the cell set to which the cell actually scheduled by the first downlink control information belongs, as indicated by the network device, is MC-DCI-setofCells2, the terminal may determine the cell set to which the cell actually scheduled by MC-DCI 0_3 belongs based on ScheduledCell-ListDCI-0-3.

[0252] In some embodiments, for example, as shown in FIG3 , for MC-DCI 1_3, the network device may indicate to the terminal the cell set to which the cell actually scheduled by MC-DCI 1_3 belongs through the information element ScheduledCell-ListDCI-1-3 in the RRC signaling. The cell set to which the cell actually scheduled by MC-DCI 1_3 belongs corresponds to the cell set to which the cell actually scheduled by the first downlink control information belongs. For example, when the cell set to which the cell actually scheduled by the first downlink control information belongs, as indicated by the network device, is MC-DCI-setofCells2, the terminal may determine the cell set to which the cell actually scheduled by MC-DCI 1_3 belongs based on ScheduledCell-ListDCI-1-3.

[0253] In some embodiments, the network device may indicate to the terminal the cell combinations that can be scheduled by the first downlink control information. For example, for MC-DCI 0_3, as shown in FIG3 , the network device may indicate the cell combinations that can be scheduled by MC-DCI 0_3 through the information element ScheduledCellComboListDCI-0-3 under ScheduledCell-ListDCI-0-3, for example, a cell combination list may be indicated. For example, in FIG3 , the cell combinations that can be scheduled by MC-DCI 0_3 include ScheduledCellCombo0 to ScheduledCellComb15, a total of 16 cell combinations, and the corresponding combination indexes are 0 to 15, respectively.

[0254] In some embodiments, the network device may indicate to the terminal the cell combination actually scheduled by MC-DCI 0_3, where the cell combination may include at least one cell. For example, the network device may indicate to the terminal the cell combination actually scheduled by MC-DCI 0_3 through an information field in the first downlink control information. For example, the network device may indicate to the terminal the cell combination actually scheduled by MC-DCI 0_3 through a scheduled cells indicator information field in the first downlink control information. The cell combination actually scheduled by MC-DCI 0_3 belongs to the list of cell combinations that can be scheduled by MC-DCI 0_3 indicated by ScheduledCellComboListDCI-0-3. For example, in FIG3 , the cell combination actually scheduled by MC-DCI 0_3 indicated to the terminal by the Scheduled cells indicator is the cell combination ScheduledCellCombo1 corresponding to index 1.

[0255] Among them, when the network device does not indicate the list of cell combinations that can be scheduled by the first downlink control information, for example, ScheduledCellComboListDCI-0-3 is not configured, the cell combination actually scheduled by the first downlink control information can be indicated through the frequency domain resource assignment (FDRA) field.

[0256] In some embodiments, the network device may indicate to the terminal the cell combinations that can be scheduled by the first downlink control information. For example, for MC-DCI 1_3, as shown in FIG3 , the network device may indicate the cell combinations that can be scheduled by MC-DCI 1_3 through the information element ScheduledCellComboListDCI-1-3 under ScheduledCell-ListDCI-1-3, for example, a cell combination list may be indicated. For example, in FIG3 , the cell combinations that can be scheduled by MC-DCI 1_3 include ScheduledCellCombo0 to ScheduledCellComb15, a total of 16 cell combinations, and the corresponding indexes are 0 to 15, respectively.

[0257] In some embodiments, the network device may indicate to the terminal the cell combination actually scheduled by MC-DCI 1_3, where the cell combination may include at least one cell. For example, the network device may indicate to the terminal the cell combination actually scheduled by MC-DCI 1_3 through an information field in the first downlink control information. For example, the network device may indicate to the terminal the cell combination actually scheduled by MC-DCI 1_3 through a scheduled cells indicator information field in the first downlink control information. The cell combination actually scheduled by MC-DCI 1_3 belongs to the list of cell combinations that can be scheduled by MC-DCI 1_3 indicated by ScheduledCellComboListDCI-1-3. For example, in FIG3 , the cell combination actually scheduled by MC-DCI 1_3 indicated to the terminal by the Scheduled cells indicator is the cell combination ScheduledCellCombo1 corresponding to index 1.

[0258] Among them, when the network device does not indicate the list of cell combinations that can be scheduled by the first downlink control information, for example, ScheduledCellComboListDCI-1-3 is not configured, it can indicate the cell combination actually scheduled by the first downlink control information through the frequency domain resource allocation (FDRA) field.

[0259] In some embodiments, the cells that can be scheduled by the first downlink control information can be determined based on the configuration information of the network device or based on predefined rules, which is not limited in this disclosure. The cells that can be scheduled by the first downlink control information are used to represent the capability range of the first downlink control information, and the cells actually scheduled belong to the cells that can be scheduled by the first downlink control information.

[0260] In some embodiments, the first downlink control information includes at least one information field, which may also be referred to as a field. Since the first downlink control information can be used to schedule multiple cells, the information field in the first downlink control information can schedule at least one of the multiple cells. Therefore, it is necessary to determine the size of the information field, that is, the number of bits of information used, in order to accurately parse the information field.

[0261] In some embodiments, the information field scheduling cell means that the information indicated by the information field can be used to schedule the terminal in the applicable cell. For example, taking the information field of the Channel State Information (CSI) request (e.g., called CSI Request) as an example, the CSI Request can indicate to the terminal in the applicable cell whether the network device requests the terminal to report channel state information. In other words, the CSI Request is used to schedule whether the terminal reports channel state information in the applicable cell.

[0262] In a first aspect, embodiments of the present disclosure provide an information determination method. In some embodiments, the information determination method may be executed by a terminal, and the information determination method may include the following steps:

[0263] The second size of the first information field in the first downlink control information for scheduling multiple cells is determined according to at least one of the following first sizes:

[0264] a 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, or

[0265] a first size of a first information field corresponding to a first reference cell in a cell combination corresponding to the first downlink control information;

[0266] In some embodiments, the first downlink control information may include one or more information fields, wherein some information fields do not need to be applied to all cells among the cells actually scheduled by the first downlink control information, but only need to be applied to some cells among the cells actually scheduled by the first downlink control information. Such information fields may be referred to as first information, and the first information fields may be applied to some cells among the cells actually scheduled by the first downlink control information. That is, the first information field may be an information field included in the first downlink control information that is applied to some cells among the cells actually scheduled by the first downlink control information. For example, the type of the first information field may be referred to as type 1C.

[0267] It should be noted that, in some embodiments, the information field applied to a cell may mean that the information indicated by the information field can 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, which indicates a value of 3, meaning that the report trigger state corresponding to the value 3 is triggered. Then, the CSI Request field applied to cell #1 means that the report trigger state corresponding to the value 3 for cell #1 is triggered. The terminal can perform corresponding CSI measurement reporting in cell #1 based on the triggered trigger state configuration according to the CSI Request field.

[0268] For example, the cells actually scheduled by the first downlink control information include three cells, namely cell #1 with an index of 1, cell #2 with an index of 2, and cell #3 with an index of 3. The first information domain is applied to some of these three cells, for example, it can be applied to cell #1 and cell #2, for example, it can be applied to cell #2 and cell #3, for example, it can be applied to cell #1 and cell #3, for example, it can be applied to cell #1, for example, it can be applied to cell #2, for example, it can be applied to cell #3.

[0269] In some embodiments, the portion of cells to which the first information field applies includes: the cell with the smallest index among the cells actually scheduled by the first downlink control information. That is, the first information field may be the information field within the information field included in the first downlink control information that applies to the cell with the smallest index among the cells actually scheduled by the first downlink control information. For example, taking the example where the cells actually scheduled by the first downlink control information include cell #1 with an index of 1, cell #2 with an index of 2, and cell #3 with an index of 3, the first information field may be the information field within the information field included in the first downlink control information that applies to cell #1.

[0270] Figure 4 is a schematic flow chart of a method for determining information according to an embodiment of the present disclosure. The method for determining information shown in this embodiment can be executed by a terminal.

[0271] As shown in FIG4 , 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 each cell in the cell set to which the cell corresponding to the first downlink control information belongs includes:

[0272] In step S401, the second size of the first information field in the first downlink control information is determined according to the 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.

[0273] It should be noted that the embodiment shown in FIG. 4 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0274] In some embodiments, the first information field includes at least one of the following: a channel state information request (eg, CSI Request) information field, and an uplink shared channel indication (eg, UL-SCH indicator) information field.

[0275] In some embodiments, for each cell in the cell set to which the cell corresponding to the first downlink control information belongs, the terminal can determine the first size of the first information field corresponding to the cell. For example, the first size of the first information field corresponding to each cell can be determined according to the method of determining the size of the information field in the traditional downlink control information. For example, the network device can send a report trigger size (e.g., reportTriggerSize) signaling to the terminal on cell #1 to indicate the first size of the CSI Request field corresponding to cell #1.

[0276] Taking the first information field including the CSI Request field as an example, the network device can indicate the first size of the CSI request field for each cell through report trigger size (e.g., reportTriggerSize) signaling. The terminal can determine the first size of the CSI request field corresponding to each cell based on the report trigger size signaling sent by the network device.

[0277] Because the first downlink control information is used to schedule multiple cells, and the network device indicates 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, and the first size of the first information field corresponding to different cells can be different, it is necessary to clearly determine how to determine the size of the first information field in the first downlink control information in order to accurately parse the first information field.

[0278] According to an embodiment of the present disclosure, a terminal can determine the second size of the first information field in the first downlink control information based on the 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. Accordingly, for the first information field in the first downlink control information, the second size of the information field can be clearly determined based on the maximum value of the first size of the first information field corresponding to each cell in the cell set, so as to accurately parse the first information field based on the second size. This is conducive to avoiding problems caused by not clearly determining the first size of the first information field of the first information field in the first control information based on which cell in the multiple cells corresponds to the first size of the first information field when the first downlink control information schedules multiple cells.

[0279] In some embodiments, the second size of the first information field in the first downlink control information is equal to a maximum value.

[0280] In some embodiments, the cell set to which the cell corresponding to the first downlink control information belongs includes at least one of the following:

[0281] The cell set to which the cell that can be scheduled by the first downlink control information belongs;

[0282] The cell set to which the cell actually scheduled by the first downlink control information belongs may also be referred to as the cell set to which the cell scheduled by the first downlink control information belongs.

[0283] For example, taking the cell set to which the cell corresponding to the first downlink control information belongs as an example, including the cell set to which the cell that can be scheduled by the first downlink control information belongs, for example, the cell set to which the cell that can be scheduled by the first downlink control information belongs is {1, 2, 3, 4}, that is, including cell #1 with an index of 1, cell #2 with an index of 2, cell #3 with an index of 3, and cell #4 with an index of 4.

[0284] 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; and 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 field corresponding to each cell in the cell set is 5, so the terminal can determine that the first information field in the first downlink control information occupies 5 bits.

[0285] For example, taking the 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, including cell #1 with an index of 1, cell #2 with an index of 2, and cell #3 with an index of 3.

[0286] 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; and 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.

[0287] The following describes, through several embodiments, a method for determining the second size of the first information field in the first downlink control information.

[0288] Taking the first information field including the CSI Request information field as an example, the second size of the CSI Request information field in the first downlink control information is equal to in, It refers to the number of cells in the cell set to which the cell actually scheduled by the first downlink control information belongs. r is mapped one by one based on the order of cell index from small to large, where r=1 corresponds to the cell with the smallest index in the cell set. M c (r) represents the first size of the first information field corresponding to the rth cell in the cell set. c (r) It can be determined based on high-level parameters, for example, based on the report trigger size (for example, reportTriggerSize). For example, the first size can range from 0 to 6.

[0289] Taking the first information field including the UL-SCH indicator information field as an example, the second size of the UL-SCH indicator information field in the first downlink control information is equal to in, It refers to the number of cells in the cell set to which the cell actually scheduled by the first downlink control information belongs. r is mapped one by one based on the order of cell index from small to large, where r=1 corresponds to the cell with the smallest index in the cell set. M c (r) represents the first size of the first information field corresponding to the rth cell in the cell set. When the number of scheduled PUSCHs indicated by the Time Domain Resource Assignment (TDRA) field is 1, M c The first dimension of (r) is 0, otherwise, M c The first dimension of (r) is 1. c When the first size of (r) is 1, if the value of this bit is 1, the corresponding UL-SCH is transmitted on the PUSCH; if the value of this bit is 0, the corresponding UL-SCH is not transmitted on the PUSCH.

[0290] 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, that is, the terminal does not expect to receive the first downlink control information in which the value of the CSI Request information field is 0 and the value of the UL-SCH indicator information field is 0.

[0291] 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:

[0292] The terminal is configured with a first signaling, and determines the second size of the first information field in the first downlink control information based on 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; wherein the first signaling is used to indicate the cell combination corresponding to the first downlink control information.

[0293] In some embodiments, the information determination method also includes: when the terminal is not configured with the first signaling, determining the second size of the first information field in the first downlink control information based on the 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.

[0294] In some embodiments, the network device may configure first signaling for the terminal, where the first signaling is used to indicate a cell combination corresponding to the first downlink control information.

[0295] When the terminal is configured with the first signaling, the terminal can determine the cell combination corresponding to the first downlink control information, and then the terminal can determine the first reference cell in the cell combination; determine the second size of the first information field in the first downlink control information based on the first reference cell, for example, it can be determined that the second size is equal to the size of the first information field corresponding to the first reference cell.

[0296] When the terminal is not configured with the first signaling, the terminal cannot determine the cell combination corresponding to the first downlink control information. Then the terminal can determine the 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, and determine the second size of the first information field in the first downlink control information based on the maximum value.

[0297] In some embodiments, the cell combination corresponding to the first downlink control information includes at least one of the following:

[0298] A cell combination that can be scheduled by the first downlink control information;

[0299] The cell combination actually scheduled by the first downlink control information.

[0300] For example, the first signaling includes at least one of the following:

[0301] ScheduledCellCombo-ListDCI-0-3;

[0302] ScheduledCellCombo-ListDCI-1-3.

[0303] In some embodiments, the first reference cell includes at least one of the following:

[0304] The cell with the smallest cell index in the cell combination;

[0305] The cell with the largest cell index in the cell combination;

[0306] The cell with the largest corresponding first information field in the cell combination.

[0307] In some embodiments, the terminal may determine a cell combination corresponding to the first downlink control information, and then the terminal may determine a first reference cell in the cell combination; and determine the second size of the first information field in the first downlink control information according to the first reference cell.

[0308] 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:

[0309] The first reference cell is a cell with the smallest cell index in the cell combination.

[0310] In one possible implementation, the terminal determines the cell actually scheduled by the first downlink control information based on a specific information field of the first downlink control information, such as indication information in a scheduled cells indicator field or a frequency domain resource assignment field. The terminal also determines 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 among the actually scheduled cells.

[0311] In some embodiments, for example, the first information field includes a CSI request field. The actual scheduled cell may be indicated by the Scheduled cells indicator field or the Frequency domain resource assignment field, and the size of the CSI request field may be determined based on the reportTriggerSize of the cell with the smallest index (e.g., serving cell index) among the actual scheduled cells. For example, the size of the CSI request field may be 0, 1, 2, 3, 4, 5, or 6 bits. The CSI request field is applied to the cell with the smallest index.

[0312] In some embodiments, the first information field includes a UL-SCH indicator field. The size of the UL-SCH indicator field accounts for the number of bits M. U (r), where r refers to the cell with the smallest index (e.g., serving cell index) among the cells actually scheduled indicated by the Scheduled cells indicator field or the Frequency domain resource assignment field. U (r) can be determined by:

[0313] When the number of actually scheduled PUSCHs indicated by the Time domain resource assignment field is greater than 1, M U (r) is 0 bit.

[0314] Otherwise, M U(r) is 1 bit. When the value is 1, it is used to indicate that UL-SCH should be transmitted on PUSCH, and when the value is 0, it is used to indicate that UL-SCH should not be transmitted on PUSCH. When the terminal does not support triggering SRS (Sounding Reference Signal) only on DCI, 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 the CRC (Cyclic Redundancy Check) of DCI format 0_1 ​​is preempted by SP-CSI-RNTI (Semi-Persistent Channel State Information Radio Network Temporary Identifier). When the terminal supports triggering SRS only on DCI, 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 and the SRS request field is all 0, unless the CRC of DCI format 0_1 ​​is preempted by SP-CSI-RNTI.

[0315] RNTI stands for Radio Network Temporary Indentifier, and SP stands for Semi-Persistent.

[0316] For example, the cell combination corresponding to the first downlink control information may include one or more cell combinations. For example, the cells included in the cell combination corresponding to the first downlink control information are shown in Table 1:

[0317] Table 1

[0318] As shown in Table 1, take the example where the cell combination corresponding to the first downlink control information includes two small combinations, namely cell combination #1 and cell combination #2, where cell combination #1 includes cell #1 and cell #2, and cell combination #2 includes cell #2 and cell #4.

[0319] When the first reference cell includes the cell with the smallest cell index in the cell combination, the cell with the smallest cell index in the two cell combinations can be determined to be cell #1. Furthermore, the second size of the first information field in the first downlink control information can be determined to be the size of the first information field corresponding to cell #1, for example, the second size is 2.

[0320] When the first reference cell includes the cell with the largest cell index in the cell combination, it can be determined that the cell with the largest cell index in the two cell combinations is cell #4. Furthermore, the second size of the first information field in the first downlink control information can be determined to be the size of the first information field corresponding to cell #4, for example, the second size is 5.

[0321] When the first reference cell includes the cell with the largest first information field size in the cell combination, based on the above example, the size of the first information field corresponding to cell #1 is 2, the size of the first information field corresponding to cell #2 is 3, and the size of the first information field corresponding to cell #4 is 5. Therefore, it can be determined that the size of the first information field corresponding to cell #4 is the largest, and thus the first reference cell is determined to be cell #4. Furthermore, the second size of the first information field in the first downlink control information can be determined to be the size of the first information field corresponding to cell #4, for example, the second size is 5.

[0322] In some embodiments, the information determination method also includes: 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 to which the first information field is actually applied, parsing the first information field according to the first number of bits in the proportion of the first information field to determine the information indicated by the first information field to the first cell.

[0323] In some embodiments, the first size of the first information field in the first downlink control information may be larger 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 field based on the first number of bits in the proportion of the first information field to ensure that the parsed information can be successfully applied to the first cell, thereby realizing the indication function of the first information field for the first cell.

[0324] In some embodiments, the first number is equal to the third size.

[0325] For example, the first size of the first information field in the first downlink control information is 5, and the third size of the first information field corresponding to the first cell actually used by the first information field is 4. The first size is greater than the third size, then 4 bits can be determined from the 5 bits of the first information field, and then these 4 bits can be parsed to obtain the information indicated by the first information field to the first cell.

[0326] In some embodiments, the first number of bits in the proportion of the first information field includes at least one of the following:

[0327] The first number of most significant bits in the ratio of the first information field, that is, the first number of bits starting from the most significant bit in the ratio of the first information field;

[0328] The first number of least significant bits in the ratio of the first information field is, that is, the first number of bits in the ratio of the first information field, starting from the least significant bit.

[0329] For example, the first size of the first information field in the first downlink control information is 5, the indication value is 10011, and the third size of the first information field corresponding to the first cell actually used by the first information field is 4. The first size is larger than the third size. Then, the 4-bit values ​​corresponding to the most significant bits can be determined in the 5 bits of the first information field, that is, 1001 can be parsed, and the parsing result can be used as the information indicated by the first information field to the first cell.

[0330] For example, the first size of the first information field in the first downlink control information is 5, the indication value is 10011, and the third size of the first information field corresponding to the first cell actually used by the first information field is 4. The first size is larger than the third size. Then, the 4-bit value corresponding to the least significant bit can be determined in the 5 bits of the first information field, that is, 0011 can be parsed, and the parsing result can be used as the information indicated by the first information field to the first cell.

[0331] In some embodiments, the information determination method also includes: 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, parsing the first information field by adding a second number of bits with a value of zero to the first information field to determine the information indicated by the first information field to the first cell.

[0332] 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 field by adding a second number of zero bits to the first information field to ensure that the parsed information can be successfully applied to the first cell, thereby realizing the indication function of the first information field for the first cell.

[0333] In some embodiments, the second number is equal to the difference between the third size and the second size.

[0334] For example, the first size of the first information field in the first downlink control information is 5, the third size of the first information field corresponding to the first cell actually used 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. Then, the first information field can be parsed by adding one bit with a value of 0 to the five bits of the first information field to obtain the information indicated by the first information field to the first cell.

[0335] In some embodiments, adding a second number of zero bits to the first information field comprises at least one of the following:

[0336] Adding a bit with a value of zero before the most significant bit of the first information field;

[0337] A bit with a value of zero is added after the least significant bit of the first information field.

[0338] For example, if the first size of the first information field in the first downlink control information is 5, specifically 10011, and the third size of the first information field corresponding to the first cell actually used by the first information field is 6, and the first size is smaller than the third size, then a bit with a value of 0 may be added before the most significant bit of the 5 bits of the first information field. For example, after adding the bit with a value of 0 to the first information field, 010011 is obtained, and 010011 may be parsed, and the parsed result is used as the information indicated by the first information field for the first cell.

[0339] For example, the first size of the first information field in the first downlink control information is 5, specifically 10011, and the third size of the first information field corresponding to the first cell actually used by the first information field is 6. If the first size is smaller than the third size, a bit with a value of 0 may be added after the least significant bit of the 5 bits of the first information field. For example, after adding the bit with a value of 0 to the first information field, 100110 is obtained. 100110 may be parsed, and the parsed result may be used as the information indicated by the first information field for the first cell.

[0340] In a second aspect, embodiments of the present disclosure provide an information determination method. Figure 5 is a schematic flow chart illustrating an information determination method according to an embodiment of the present disclosure. The information determination method illustrated in this embodiment can be executed by a terminal.

[0341] As shown in FIG5 , the information sending method may include the following steps:

[0342] In step S501, the size of a first information field in first downlink control information for scheduling multiple cells is determined according to first configuration signaling.

[0343] It should be noted that the embodiment shown in FIG. 5 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0344] In some embodiments, the first downlink control information may include one or more information fields, wherein some information fields do not need to be applied to all cells among the cells actually scheduled by the first downlink control information, but only need to be applied to some cells among the cells actually scheduled by the first downlink control information. Such information fields may be referred to as first information, and the first information fields may be applied to some cells among the cells actually scheduled by the first downlink control information. That is, the first information field may be an information field included in the first downlink control information that is applied to some cells among the cells actually scheduled by the first downlink control information. For example, the type of the first information field may be referred to as type 1C.

[0345] For example, the cells actually scheduled by the first downlink control information include three cells, namely cell #1 with an index of 1, cell #2 with an index of 2, and cell #3 with an index of 3. The first information domain is applied to some of these three cells, for example, it can be applied to cell #1 and cell #2, for example, it can be applied to cell #2 and cell #3, for example, it can be applied to cell #1 and cell #3, for example, it can be applied to cell #1, for example, it can be applied to cell #2, for example, it can be applied to cell #3.

[0346] In some embodiments, the portion of cells to which the first information field applies includes: the cell with the smallest index among the cells actually scheduled by the first downlink control information. That is, the first information field may be the information field within the information field included in the first downlink control information that applies to the cell with the smallest index among the cells actually scheduled by the first downlink control information. For example, taking the example where the cells actually scheduled by the first downlink control information include cell #1 with an index of 1, cell #2 with an index of 2, and cell #3 with an index of 3, the first information field may be the information field within the information field included in the first downlink control information that applies to cell #1.

[0347] In some embodiments, for each cell in the cell set to which the cell corresponding to the first downlink control information belongs, the terminal can determine the first size of the first information field corresponding to the cell. For example, the first size of the first information field corresponding to each cell can be determined based on the method of determining the size of the information field in the traditional downlink control information.

[0348] In some embodiments, the first information field includes at least one of the following: a channel state information request (eg, CSI Request) information field, and an uplink shared channel indication (eg, UL-SCH indicator) information field.

[0349] Taking the first information field including the CSI Request field as an example, the network device can indicate the first size of the CSI request field for each cell through report trigger size (e.g., reportTriggerSize) signaling. The terminal can determine the first size of the CSI request field corresponding to each cell based on the report trigger size signaling sent by the network device.

[0350] Because the first downlink control information is used to schedule multiple cells, and the network device indicates 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, and the first size of the first information field corresponding to different cells can be different, it is necessary to clearly determine how to determine the size of the first information field in the first downlink control information in order to accurately parse the first information field.

[0351] According to an embodiment of the present disclosure, a network device may send a first configuration signaling to a terminal. The first configuration signaling includes but is not limited to RRC signaling. The first configuration signaling may indicate the size of the first information field in the first downlink control information of the terminal. The terminal may receive the first configuration signaling sent by the network device, and then determine the size of the first information field in the first downlink control information based on the first configuration signaling, so that after receiving the first downlink control information, the first information field in the first downlink control information may be parsed according to the determined size. This is beneficial for avoiding problems caused by determining the size of the first information field in the first control information based on the size of the first information field corresponding to a cell in the first downlink control information when the first downlink control information schedules multiple cells. It can also ensure that the terminal and the base station have a consistent understanding of the size of the first information field.

[0352] In some embodiments, the first configuration signaling is determined based on a reference cell.

[0353] For example, the first configuration signaling may be determined based on a 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 based on the size of the first information field corresponding to the reference cell.

[0354] Take the example where the first downlink control information includes DCI 0_3 and the first information field includes the CSI Request information field.

[0355] In some embodiments, the size of the CSI Request information field may be determined based on higher layer parameters in the reference cell, such as the report trigger size (e.g., reportTriggerSizeDCI-0-3). For example, the size of the CSI Request information field may range from 0 to 6.

[0356] Take the example where the first downlink control information includes DCI 0_3 and the first information field includes the UL-SCH indicator information field.

[0357] In some embodiments, the size of the UL-SCH indicator information field may be determined based on higher-layer parameters in a reference cell. For example, the size may be determined based on uplink shared channel downlink control information (e.g., UL-SCHDCI-0-3). If UL-SCHDCI-0-3 is not enabled or disabled, or the indication value is 0 / 1, the size of the UL-SCH indicator information field is 0. If UL-SCHDCI-0-3 is enabled or the indication value is 1 / 0, the size of the UL-SCH indicator information field is 1.

[0358] In some embodiments, the reference cell includes at least one of the following:

[0359] Scheduling cell (the cell where the terminal receives the first downlink control information);

[0360] a cell with the largest cell index in the cell combination corresponding to the first downlink control information;

[0361] the cell with the smallest cell index in the cell combination corresponding to the first downlink control information;

[0362] a cell with the largest cell index in the cell set to which the cell corresponding to the first downlink control information belongs;

[0363] a cell with the smallest cell index in the cell set to which the cell corresponding to the first downlink control information belongs;

[0364] a cell with the largest size of the first information field in the cell set to which the cell corresponding to the first downlink control information belongs;

[0365] a cell for calculating a size of the first downlink control information;

[0366] A cell used to calculate blind detection resources of the first downlink control information, for example, the blind detection resources include at least one of the following: BD, CCE, where BD represents blind detection (Blind Detection) and CCE represents control channel element (Control Channel Element)).

[0367] In some embodiments, the cell combination corresponding to the first downlink control information includes at least one of the following:

[0368] A cell combination that can be scheduled by the first downlink control information;

[0369] A cell combination actually scheduled by the first downlink control information;

[0370] and / or

[0371] The cell set to which the cell corresponding to the first downlink control information belongs includes at least one of the following:

[0372] The cell set to which the cell that can be scheduled by the first downlink control information belongs;

[0373] The cell set to which the cell actually scheduled by the first downlink control information belongs.

[0374] In some embodiments, the information determination method further includes: ignoring traditional configuration signaling, wherein the traditional configuration signaling is used to indicate the size of the first information field in the traditional downlink control information.

[0375] When the first configuration signaling for the first downlink control information (eg, reportTriggerSizeDCI-0-3, but not limited to reportTriggerSizeDCI-0-3) is configured for the terminal, the terminal may ignore the traditional configuration signaling, eg, reportTriggerSize.

[0376] For example, configuration signaling of legacy downlink control information (legacy DCI, DCI used only for scheduling one cell) in each cell in the cell set to which the cell corresponding to the first downlink control information belongs may be ignored.

[0377] Taking the first information field including the CSI request information field as an example, the size of the CSI request information field is determined based on the first configuration signaling reportTriggerSize-MC-DCI. Then, the size of the CSI request corresponding to a cell in the actual scheduling cell can be determined based on the first configuration signaling reportTriggerSize-MC-DCI.

[0378] It is not necessary to determine the size of the CSI request corresponding to each cell 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. 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 can parse the signaling, but does not determine the size of the CSI request corresponding to cell #1 based on the parsing result.

[0379] In some embodiments, the cell set to which the cell corresponding to the first downlink control information belongs includes at least one of the following: the cell set to which the cell that can be scheduled by the first downlink control information belongs; and the cell set to which the cell actually scheduled by the first downlink control information belongs.

[0380] In some embodiments, the first configuration signaling is configured based on a cell set. That is, the terminal can determine the size of the corresponding first information field in the first downlink information based on the first configuration signaling. And / or, the terminal can determine the parsing information 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 based on the first configuration signaling. For example, the terminal determines the first size of the first information field corresponding to each cell based on the first configuration signaling, thereby determining the indication value of the first information field in the first downlink control information, that is, the indication 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 for a cell in the cell set, the terminal can determine the size of the CSI request information field corresponding to each of the above four cells based on reportTriggerSizeDCI-0-3, thereby determining the parsing method of the CSI request information field corresponding to 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 based on the first configuration signaling.

[0381] 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 following steps:

[0382] The second size of the first information field in the first downlink control information for scheduling multiple cells is determined according to at least one of the following first sizes:

[0383] a 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, or

[0384] a first size of a first information field corresponding to a first reference cell in a cell combination corresponding to the first downlink control information;

[0385] In some embodiments, the first downlink control information may include one or more information fields, wherein some information fields do not need to be applied to all cells among the cells actually scheduled by the first downlink control information, but only need to be applied to some cells among the cells actually scheduled by the first downlink control information. Such information fields may be referred to as first information, and the first information fields may be applied to some cells among the cells actually scheduled by the first downlink control information. That is, the first information field may be an information field included in the first downlink control information that is applied to some cells among the cells actually scheduled by the first downlink control information. For example, the type of the first information field may be referred to as type 1C.

[0386] It should be noted that, in some embodiments, "the information field applies to a cell" may mean that the information indicated by the information field applies to that cell. For example, in the case of a channel state information request (e.g., CSI Request) information field, the information indicated by the CSI Request field is 00011, which indicates a value of 3, indicating a request to report three CSIs. Therefore, if the CSI Request field applies to cell #1, it means a request to report three CSIs for cell #1. Based on the CSI Request field, the terminal can determine the three CSIs by measuring the reference signal in cell #1 and send the three CSIs to the network device.

[0387] For example, the cells actually scheduled by the first downlink control information include three cells, namely cell #1 with an index of 1, cell #2 with an index of 2, and cell #3 with an index of 3. The first information domain is applied to some of these three cells, for example, it can be applied to cell #1 and cell #2, for example, it can be applied to cell #2 and cell #3, for example, it can be applied to cell #1 and cell #3, for example, it can be applied to cell #1, for example, it can be applied to cell #2, for example, it can be applied to cell #3.

[0388] In some embodiments, the portion of cells to which the first information field applies includes: the cell with the smallest index among the cells actually scheduled by the first downlink control information. That is, the first information field may be the information field within the information field included in the first downlink control information that applies to the cell with the smallest index among the cells actually scheduled by the first downlink control information. For example, taking the example where the cells actually scheduled by the first downlink control information include cell #1 with an index of 1, cell #2 with an index of 2, and cell #3 with an index of 3, the first information field may be the information field within the information field included in the first downlink control information that applies to cell #1.

[0389] 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 each cell in the cell set to which the cell corresponding to the first downlink control information belongs includes:

[0390] The second size of the first information field in the first downlink control information is determined according to the first size of the first information field 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 smallest index among the cells actually scheduled by the first downlink control information.

[0391] Figure 6 is a schematic flow chart of a method for determining information according to an embodiment of the present disclosure. The method for determining information shown in this embodiment can be executed by a network device.

[0392] As shown in FIG6 , 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 each cell in the cell set to which the cell corresponding to the first downlink control information belongs includes:

[0393] In step S601, the second size of the first information field in the first downlink control information is determined according to the 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.

[0394] In some embodiments, the first information field includes at least one of the following: a channel state information request (eg, CSI Request) information field, and an uplink shared channel indication (eg, UL-SCH indicator) information field.

[0395] In some embodiments, for each cell in the cell set to which the cell corresponding to the first downlink control information belongs, the network device can determine the first size of the first information field corresponding to the cell. For example, the first size of the first information field corresponding to each cell can be determined according to the method of determining the size of the information field in the traditional downlink control information. For example, the network device can send a report trigger size (e.g., reportTriggerSize) signaling to the terminal on cell #1 to indicate the first size of the CSI Request field corresponding to cell #1.

[0396] Taking the first information field including the CSI Request field as an example, the network device can indicate the first size of the CSI request field for each cell through report trigger size (e.g., reportTriggerSize) signaling. The terminal can determine the first size of the CSI request field corresponding to each cell based on the report trigger size signaling sent by the network device.

[0397] Because the first downlink control information is used to schedule multiple cells, and the network device indicates 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, and the first size of the first information field corresponding to different cells can be different, it is necessary to clearly determine how to determine the size of the first information field in the first downlink control information in order to accurately parse the first information field.

[0398] According to an embodiment of the present disclosure, a network device can determine the second size of the first information field in the first downlink control information based on the 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. Accordingly, for the first information field in the first downlink control information, the second size of the information field can be clearly determined based on the maximum value of the first size of the first information field corresponding to each cell in the cell set, so as to accurately parse the first information field based on the second size. This is conducive to avoiding problems caused by not determining the second size of the first information field in the first control information based on which cell among the multiple cells corresponds to the first size of the first information field when the first downlink control information schedules multiple cells.

[0399] In some embodiments, the second size of the first information field in the first downlink control information is equal to a maximum value.

[0400] In some embodiments, the cell set to which the cell corresponding to the first downlink control information belongs includes at least one of the following:

[0401] The cell set to which the cell that can be scheduled by the first downlink control information belongs;

[0402] The cell set to which the cell actually scheduled by the first downlink control information belongs may also be referred to as the cell set to which the cell scheduled by the first downlink control information belongs.

[0403] For example, taking the cell set to which the cell corresponding to the first downlink control information belongs as an example, including the cell set to which the cell that can be scheduled by the first downlink control information belongs, for example, the cell set to which the cell that can be scheduled by the first downlink control information belongs is {1, 2, 3, 4}, that is, including cell #1 with an index of 1, cell #2 with an index of 2, cell #3 with an index of 3, and cell #4 with an index of 4.

[0404] 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; and 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 field corresponding to each cell in the cell set is 5, so the network device can determine that the first information field in the first downlink control information occupies 5 bits.

[0405] For example, taking the 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, including cell #1 with an index of 1, cell #2 with an index of 2, and cell #3 with an index of 3.

[0406] 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; and 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 can determine that the second size of the first information field in the first downlink control information is 4.

[0407] The following describes, through several embodiments, a method for determining the second size of the first information field in the first downlink control information.

[0408] Taking the first information field including the CSI Request information field as an example, the second size of the CSI Request information field in the first downlink control information is equal to in, It refers to the number of cells in the cell set to which the cell actually scheduled by the first downlink control information belongs. r is mapped one by one based on the order of cell index from small to large, where r=1 corresponds to the cell with the smallest index in the cell set. M c (r) represents the first size of the first information field corresponding to the rth cell in the cell set. c (r) It can be determined based on high-level parameters, for example, based on the report trigger size (for example, reportTriggerSize). For example, the first size can range from 0 to 6.

[0409] Taking the first information field including the UL-SCH indicator information field as an example, the second size of the UL-SCH indicator information field in the first downlink control information is equal to in, It refers to the number of cells in the cell set to which the cell actually scheduled by the first downlink control information belongs. r is mapped one by one based on the order of cell index from small to large, where r=1 corresponds to the cell with the smallest index in the cell set. M c (r) represents the first size of the first information field corresponding to the rth cell in the cell set. When the number of scheduled PUSCHs indicated by the Time Domain Resource Assignment (TDRA) field is 1, M c The first dimension of (r) is 0, otherwise, M c The first dimension of (r) is 1. c When the first size of (r) is 1, if the value of this bit is 1, the corresponding UL-SCH is transmitted on the PUSCH; if the value of this bit is 0, the corresponding UL-SCH is not transmitted on the PUSCH.

[0410] 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 send such first downlink control information, that is, may not send the first downlink control information in which the value of the CSI Request information field 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, that is, may not expect to receive the first downlink control information in which the value of the CSI Request information field is 0 and the value of the UL-SCH indicator information field is 0.

[0411] 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:

[0412] A first signaling is configured for the terminal, and the second size of the first information field in the first downlink control information is determined based on 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; wherein the first signaling is used to indicate the cell combination corresponding to the first downlink control information.

[0413] In some embodiments, the information determination method also includes: when the first signaling is not configured for the terminal, determining the second size of the first information field in the first downlink control information based on the 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.

[0414] In some embodiments, the network device may configure first signaling for the terminal, where the first signaling is used to indicate a cell combination corresponding to the first downlink control information.

[0415] When the first signaling is not configured in the terminal, the network device can determine the cell combination corresponding to the first downlink control information, then the network device can determine the first reference cell in the cell combination; determine the second size of the first information field in the first downlink control information based on the first reference cell, for example, it can be determined that the second size is equal to the size of the first information field corresponding to the first reference cell.

[0416] When the first signaling is not configured for the terminal, the network device has not yet determined the cell combination corresponding to the first downlink control information. In this case, the network device can determine the 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, and determine the second size of the first information field in the first downlink control information based on the maximum value.

[0417] In some embodiments, the cell combination corresponding to the first downlink control information includes at least one of the following:

[0418] A cell combination that can be scheduled by the first downlink control information;

[0419] The cell combination actually scheduled by the first downlink control information.

[0420] For example, the first signaling includes at least one of the following:

[0421] ScheduledCellCombo-ListDCI-0-3;

[0422] ScheduledCellCombo-ListDCI-1-3.

[0423] In some embodiments, the first reference cell includes at least one of the following:

[0424] The cell with the smallest cell index in the cell combination;

[0425] The cell with the largest cell index in the cell combination;

[0426] The cell with the largest first information field corresponding to each cell in the cell combination.

[0427] In some embodiments, the terminal may determine a cell combination corresponding to the first downlink control information, and then the terminal may determine a first reference cell in the cell combination; and determine the second size of the first information field in the first downlink control information according to the first reference cell.

[0428] For example, the cell combination corresponding to the first downlink control information may include one or more cell combinations. For example, the cell combination corresponding to the first downlink control information may include cells such as those shown in Table 1 above.

[0429] As shown in Table 1, take the example where the cell combination corresponding to the first downlink control information includes two small combinations, namely cell combination #1 and cell combination #2, where cell combination #1 includes cell #1 and cell #2, and cell combination #2 includes cell #2 and cell #4.

[0430] When the first reference cell includes the cell with the smallest cell index in the cell combination, the cell with the smallest cell index in the two cell combinations can be determined to be cell #1. Furthermore, the second size of the first information field in the first downlink control information can be determined to be the size of the first information field corresponding to cell #1, for example, the second size is 2.

[0431] When the first reference cell includes the cell with the largest cell index in the cell combination, it can be determined that the cell with the largest cell index in the two cell combinations is cell #4. Furthermore, the second size of the first information field in the first downlink control information can be determined to be the size of the first information field corresponding to cell #4, for example, the second size is 5.

[0432] When the first reference cell includes the cell with the largest first information field size in the cell combination, based on the above example, the size of the first information field corresponding to cell #1 is 2, the size of the first information field corresponding to cell #2 is 3, and the size of the first information field corresponding to cell #4 is 5. Therefore, it can be determined that the size of the first information field corresponding to cell #4 is the largest, and thus the first reference cell is determined to be cell #4. Furthermore, the second size of the first information field in the first downlink control information can be determined to be the size of the first information field corresponding to cell #4, for example, the second size is 5.

[0433] In some embodiments, the information determination method further includes: 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 to which the first information field is actually applied, determining the information indicated by the first information field to the first cell based on the first number of bits in the proportion of the first information field.

[0434] In some embodiments, the first size of the first information field in the first downlink control information may be greater 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 field for the first cell based on the first number of bits in the proportion of the first information field, so as to ensure that the information indicated by the first information field can be successfully applied to the first cell, thereby realizing the indication function of the first information field for the first cell.

[0435] In some embodiments, the first number is equal to the third size.

[0436] For example, the first size of the first information field in the first downlink control information is 5, and the third size of the first information field corresponding to the first cell actually used by the first information field is 4. The first size is greater than the third size. Then the network device can determine 4 bits out of the 5 bits of the first information field, and then determine the information indicated by the first information field to the first cell based on these 4 bits.

[0437] In some embodiments, the first number of bits in the proportion of the first information field includes at least one of the following:

[0438] The first number of most significant bits in the ratio of the first information field, that is, the first number of bits starting from the most significant bit in the ratio of the first information field;

[0439] The first number of least significant bits in the ratio of the first information field is, that is, the first number of bits in the ratio of the first information field, starting from the least significant bit.

[0440] For example, the first size of the first information field in the first downlink control information is 5, the indication value is 10011, and the third size of the first information field corresponding to the first cell actually used by the first information field is 4. The first size is larger than the third size. Then, the 4-bit value corresponding to the most significant bit can be determined in the 5 bits of the first information field, that is, 1001. The network device can determine the information indicated by the first information field to the first cell based on 1001.

[0441] For example, the first size of the first information field in the first downlink control information is 5, the indication value is 10011, and the third size of the first information field corresponding to the first cell actually used by the first information field is 4. The first size is larger than the third size. Then, the 4-bit value corresponding to the least significant bit can be determined in the 5 bits of the first information field, that is, 0011. The network device can determine the information indicated by the first information field to the first cell based on 0011.

[0442] In some embodiments, the information determination method further includes: 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, determining the information indicated by the first information field to the first cell by adding a second number of bits with a value of zero to the first information field.

[0443] 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 field for the first cell by adding a second number of zero bits to the first information field, thereby ensuring that the information indicated by the first information field can be successfully applied to the first cell, thereby realizing the indication function of the first information field for the first cell.

[0444] In some embodiments, the second number is equal to the difference between the third size and the second size.

[0445] For example, the first size of the first information field in the first downlink control information is 5, the third size of the first information field corresponding to the first cell actually used 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. Then, the information indicated by the first information field to the first cell can be determined by adding one bit with a value of 0 to the five bits of the first information field.

[0446] In some embodiments, adding a second number of zero bits to the first information field comprises at least one of the following:

[0447] adding a second number of bits having a value of zero before the most significant bit of the first information field;

[0448] A second number of bits having a value of zero are added after the least significant bit of the first information field.

[0449] For example, the first size of the first information field in the first downlink control information is 5, specifically 10011, and the third size of the first information field corresponding to the first cell actually used by the first information field is 6. If the first size is smaller than the third size, a bit with a value of 0 may be added before the most significant bit of the 5 bits of the first information field. For example, after adding the bit with a value of 0 to the first information field, 010011 is obtained, and then the information indicated by the first information field for the first cell can be determined based on 010011.

[0450] For example, the first size of the first information field in the first downlink control information is 5, specifically 10011, and the third size of the first information field corresponding to the first cell actually used by the first information field is 6. If the first size is smaller than the third size, a bit with a value of 0 may be added after the least significant bit of the 5 bits of the first information field. For example, after adding the bit with a value of 0 to the first information field, 100110 is obtained, and then the information indicated by the first information field for the first cell can be determined based on 100110.

[0451] Fourthly, embodiments of the present disclosure provide an information determination method. Figure 7 is a schematic flow chart illustrating an information determination method according to an embodiment of the present disclosure. The information determination method illustrated in this embodiment can be executed by a terminal.

[0452] As shown in FIG7 , the information sending method may include the following steps:

[0453] In step S701, configuration signaling is sent to a terminal, where the configuration signaling is used by the terminal to determine the size of a first information field in first downlink control information used for scheduling multiple cells.

[0454] It should be noted that the embodiment shown in FIG. 7 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0455] In some embodiments, the first downlink control information may include one or more information fields, wherein some information fields do not need to be applied to all cells among the cells actually scheduled by the first downlink control information, but only need to be applied to some cells among the cells actually scheduled by the first downlink control information. Such information fields may be referred to as first information, and the first information fields may be applied to some cells among the cells actually scheduled by the first downlink control information. That is, the first information field may be an information field included in the first downlink control information that is applied to some cells among the cells actually scheduled by the first downlink control information. For example, the type of the first information field may be referred to as type 1C.

[0456] For example, the cells actually scheduled by the first downlink control information include three cells, namely cell #1 with an index of 1, cell #2 with an index of 2, and cell #3 with an index of 3. The first information domain is applied to some of these three cells, for example, it can be applied to cell #1 and cell #2, for example, it can be applied to cell #2 and cell #3, for example, it can be applied to cell #1 and cell #3, for example, it can be applied to cell #1, for example, it can be applied to cell #2, for example, it can be applied to cell #3.

[0457] In some embodiments, the portion of cells to which the first information field applies includes: the cell with the smallest index among the cells actually scheduled by the first downlink control information. That is, the first information field may be the information field within the information field included in the first downlink control information that applies to the cell with the smallest index among the cells actually scheduled by the first downlink control information. For example, taking the example where the cells actually scheduled by the first downlink control information include cell #1 with an index of 1, cell #2 with an index of 2, and cell #3 with an index of 3, the first information field may be the information field within the information field included in the first downlink control information that applies to cell #1.

[0458] In some embodiments, for each cell in the cell set to which the cell corresponding to the first downlink control information belongs, the terminal can determine the first size of the first information field corresponding to the cell. For example, the first size of the first information field corresponding to each cell can be determined based on the method of determining the size of the information field in the traditional downlink control information.

[0459] In some embodiments, the first information field includes at least one of the following: a channel state information request (eg, CSI Request) information field, and an uplink shared channel indication (eg, UL-SCH indicator) information field.

[0460] Taking the first information field including the CSI Request field as an example, the network device can indicate the first size of the CSI request field for each cell through report trigger size (e.g., reportTriggerSize) signaling. The terminal can determine the first size of the CSI request field corresponding to each cell based on the report trigger size signaling sent by the network device.

[0461] Because the first downlink control information is used to schedule multiple cells, and the network device indicates 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, and the first size of the first information field corresponding to different cells can be different, it is necessary to clearly determine how to determine the size of the first information field in the first downlink control information in order to accurately parse the first information field.

[0462] According to an embodiment of the present disclosure, a network device may send a first configuration signaling to a terminal. The first configuration signaling includes but is not limited to RRC signaling. The first configuration signaling may indicate the size of the first information field in the first downlink control information of the terminal. The terminal may receive the first configuration signaling sent by the network device, and then determine the size of the first information field in the first downlink control information based on the first configuration signaling, so that after receiving the first downlink control information, the first information field in the first downlink control information may be parsed according to the determined size. This is beneficial for avoiding problems caused by determining the size of the first information field in the first control information based on the size of the first information field corresponding to a cell in the first downlink control information when the first downlink control information schedules multiple cells. It can also ensure that the terminal and the base station have a consistent understanding of the size of the first information field.

[0463] In some embodiments, the configuration signaling is sent to the terminal in a reference cell.

[0464] For example, the first configuration signaling may be determined based on a 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 based on the size of the first information field corresponding to the reference cell.

[0465] Take the example where the first downlink control information includes DCI 0_3 and the first information field includes the CSI Request information field.

[0466] In some embodiments, the size of the CSI Request information field may be determined based on higher layer parameters in the reference cell, such as the report trigger size (e.g., reportTriggerSizeDCI-0-3). For example, the size of the CSI Request information field may range from 0 to 6.

[0467] Take the example where the first downlink control information includes DCI 0_3 and the first information field includes the UL-SCH indicator information field.

[0468] In some embodiments, the size of the UL-SCH indicator information field may be determined based on higher-layer parameters in a reference cell. For example, the size may be determined based on uplink shared channel downlink control information (e.g., UL-SCHDCI-0-3). If UL-SCHDCI-0-3 is not 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 or the indication value is 1 / 0, the size of the UL-SCH indicator information field is 1.

[0469] In some embodiments, the reference cell includes at least one of the following:

[0470] Dispatching cells;

[0471] a cell with the largest cell index in the cell combination corresponding to the first downlink control information;

[0472] the cell with the smallest cell index in the cell combination corresponding to the first downlink control information;

[0473] a cell with the largest cell index in the cell set to which the cell corresponding to the first downlink control information belongs;

[0474] a cell with the smallest cell index in the cell set to which the cell corresponding to the first downlink control information belongs;

[0475] a cell with the largest size of the first information field in the cell set to which the cell corresponding to the first downlink control information belongs;

[0476] a cell for calculating a size of the first downlink control information;

[0477] A cell used to calculate blind detection resources of the first downlink control information, for example, the blind detection resources include at least one of the following: BD, CCE, where BD represents blind detection (Blind Detection) and CCE represents control channel element (Control Channel Element)).

[0478] In some embodiments, the cell combination corresponding to the first downlink control information includes at least one of the following:

[0479] A cell combination that can be scheduled by the first downlink control information;

[0480] A cell combination actually scheduled by the first downlink control information;

[0481] and / or

[0482] The cell set to which the cell corresponding to the first downlink control information belongs includes at least one of the following:

[0483] The cell set to which the cell that can be scheduled by the first downlink control information belongs;

[0484] The cell set to which the cell actually scheduled by the first downlink control information belongs.

[0485] In some embodiments, the network device may send conventional configuration signaling to the terminal in cell #1, where the conventional configuration signaling is used to indicate the size of the first information field in conventional downlink control information. However, the terminal does not parse the signaling. Alternatively, the terminal may parse the signaling but does not determine the size of the first information field corresponding to cell #1 based on the parsing result, but instead determines the size of the first information field corresponding to cell #1 based on the first configuration signaling.

[0486] 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 can parse the signaling, but does not determine the size of the CSI request corresponding to cell #1 based on the parsing result.

[0487] In some embodiments, the cell set to which the cell corresponding to the first downlink control information belongs includes at least one of the following: the cell set to which the cell that can be scheduled by the first downlink control information belongs; and the cell set to which the cell actually scheduled by the first downlink control information belongs.

[0488] In some embodiments, the network device may indicate, through a 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. 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. The network device may send a first configuration signaling reportTriggerSize-MC-DCI to the terminal, and may indicate, through reportTriggerSize-MC-DCI, the size of the CSI request information field corresponding to each cell in the above four cells. Therefore, according to this embodiment, the network device does not send, to the terminal, 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, but may 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.
