It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.

[0040] In a communication system, network-side devices can schedule the Physical Uplink Shared Channel (PUSCH) or the Physical Downlink Shared Channel (PDSCH) using Downlink Control Information (DCI).

[0041] In some scenarios, multi-cell scheduling DCI (mc-DCI) is introduced, such as DCI format 3-0 or DCI format 3-1, to schedule the PUSCH or PDSCH of one or more cells.

[0042] In some scenarios, communication systems can support the following frameworks:

[0043] Multiple cells can be divided into multiple cell sets. For example, cell set (cell1 / 2 / 3 / 4 / 5 / 6 / 7 / 8) can be divided into two cell sets (cell1 / 2 / 3 / 4) and cell set (cell5 / 6 / 7 / 8).

[0044] A cell set can be divided into multiple cell combinations. For example, a cell set (cell1 / 2 / 3 / 4) can contain cell combinations (cell1 / 2 / 3, cell1 / 2 / 4, cell1 / 3).

[0045] One MC-DCI can schedule / instruct a cell combination at a time.

[0046] There are two methods for scheduling / indicating a cell combination using MC-DCI:

[0047] Method 1: Cell indicator-based scheme

[0048] For example, Radio Resource Control (RRC) configures a cell combination table for each cell set, and each cell combination table corresponds to an index. The mc-DCI carries a field to indicate an index. For example, '01' corresponds to cell 1 / 3. If the mc-DCI indicates '01', it means that cell 1 / 3 has been scheduled / indicated. In this case, the mc-DCI only carries the frequency domain resource assignment (FDRA) for cell 1 / 3.

[0049] Method 2: FDRA-based scheme

[0050] For example, in the above example, the mc-DCI carries the FDRA fields of cell1 / 2 / 3 / 4. If the FDRA field corresponding to a certain cell indicates an invalid value, it means that the cell will not be scheduled.

[0051] In some scenarios, each cell set has a reference cell.

[0052] The number of blind detections and the DCI size for the MC-DCI of this cell set are calculated on the reference cell.

[0053] In some scenarios, each reference cell or cell set or each cell has a corresponding limit on the number of DCIs / the number of scheduling attempts.

[0054] For example, within a monitoring occasion, there are at most N1 mc-DCIs for the reference cell or cell set (which can schedule at least some of the cells in the cell set).

[0055] For example, during a monitoring occasion, there can be a maximum of N2 single-cell scheduling DCIs (sc-DCIs) for a cell within the cell set (which can schedule that cell).

[0056] When performing Downlink Assignment Index (DAI) counting, if a cell combination is scheduled, the DAI is counted for the cell with a specific ID (minimum cell ID) in that cell combination (e.g., DAI incremented by one), or the DAI is counted based on the cell with a specific ID (minimum ID) in that cell combination to generate Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) bits.

[0057] This can be considered as associating the DAI count with the DAI count of a specific ID (smallest cell ID) within the cell group.

[0058] When generating HARQ-ACK bits, the process iterates through the cell set dimension and each cell within the set, concatenating the HARQ-ACK bits corresponding to each cell to generate the target HARQ-ACK bits. The HARQ-ACK bits corresponding to a cell combination are placed in the bit position corresponding to the cell with a specific ID (smallest cell ID) within that cell combination. For cells that have not been scheduled, a corresponding Negative Acknowledgement (NACK) is generated.

[0059] In some cases, mc-DCI can carry dormancy indication information, specifically through two methods:

[0060] Method 1: Include a visible dormancy indication field;

[0061] Method 2: If the FDRA field corresponding to one or more cells is invalid, then use the modulation and coding scheme (MCS), HARQ process, and other fields corresponding to the cell with the specific ID (minimum cell ID) in these cells to indicate the sleep indication information.

[0062] In some scenarios, the terminal can perform BWP switching based on the Band Width Part (BWP) indicator of the network-side device.

[0063] For example, if the terminal is on BWP A, but the BWP indicator in the DCI points to BWP B, the terminal needs to switch from BWP A to BWP B. However, the number of bits in the information fields in this DCI is still determined according to the configuration of BWP A; for example, the number of bits in the FDRA field is still determined according to the resource allocation type and bandwidth of BWP A. But during interpretation, the terminal will truncate or pad the FDRA field before interpreting it.

[0064] In some cases, if the number of bits N required for the FDRA field in the BWP B configuration is less than the number of bits M in the FDRA field in the DCI, the terminal can interpret the actual frequency domain allocation information based on only the lowest N bits. Alternatively, it can be interpreted that the first MN bits of the FDRA field will be truncated, and the actual frequency domain allocation information will be obtained based on the remaining N bits.

[0065] In other cases, if the number of bits N required for the FDRA field corresponding to the BWP B configuration is greater than the number of bits M in the FDRA field of the DCI, the terminal will pad the M bits with NM zeros, and then interpret the resulting N bits to obtain the actual frequency domain allocation information.

[0066] In some scenarios, invalid values ​​for the FDRA field in mc-DCI are defined as follows:

[0067] For resource allocation type 0 (denoted as type0), setting the FDRA field to all zeros is an invalid value;

[0068] For resource allocation type 1 (denoted as type1), setting the FDRA field to all 1s is an invalid value;

[0069] For dynamically switching resource allocation types (denoted as dynamic), setting the FDRA field to all 1s or all 0s is an invalid value;

[0070] For resource allocation type 2 (denoted as type2) and SCS is 30kHz (i.e., μ = 1), the FDRA field is set to all zeros as an invalid value;

[0071] For resource allocation type 2, and SCS is 15kHz (i.e., μ = 0), setting the FDRA field to all 1s is an invalid value.

[0072] When the FDRA field is invalid, the cell associated with that FDRA field is not scheduled.

[0073] In some scenarios, if it is known that certain cells correspond to invalid FDRA fields, at least some information fields corresponding to those cells have a dual function in mc-DCI:

[0074] 1. The FDRA field associated with this cell indicates that the cell has not been scheduled;

[0075] 2. The MCS or other information fields associated with this cell can be used to indicate some special information, such as dormancy indication information, enhanced type 3 codebook information, or HARQ retransmission information.

[0076] To facilitate understanding of the embodiments of this application, the technical problems of this application will be explained.

[0077] Question A: In existing technology, if MC-DCI triggers a BWP handover, and the number of FDRA bits required by the BWP indicated by the BWP indicator is greater than the number of FDRA bits required by the current BWP, the terminal will pad the FDRA field with zeros and interpret the information according to the padded FDRA field. However, this design has some problems. For example, when the resource allocation type of the BWP indicated by the BWP indicator is type1 or type2 and μ=1, the FDRA field obtained after padding with zeros will not be all "1"s. Therefore, the obtained FDRA field will not indicate an invalid value. In this case, it is impossible to determine from the indication of the FDRA field that the cell has not actually been scheduled. That is, this method cannot indicate an invalid value.

[0078] Question B: If the FDRA field is modified to be interpreted based on the current BWP, and the FDRA field is an invalid FDRA, it means that the FDRA obtained by truncating or padding with zeros after invalidating the FDRA cannot be actually used for scheduling, even if the FDRA is valid scheduling information for the BWP indicated by the BWP indicator. For example, for the current BWP, FDRA = 11 is an invalid FDRA, and it needs to be padded with two zeros, resulting in FDRA 0011. This is valid scheduling information for the BWP indicated by the BWP indicator, but it cannot be actually used for scheduling.

[0079] Therefore, determining the scheduling information of the terminal's object (e.g., cell) is an urgent problem to be solved when the terminal's resource unit (e.g., BWP) is switched.

[0080] The wireless communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0081] Figure 2 is a schematic diagram of a wireless communication method provided in an embodiment of this application. As shown in Figure 2, the method 200 includes at least the following:

[0082] S210, the terminal determines target resource indication information based on the first resource unit or the target resource unit, wherein the first resource unit includes a resource unit that is used or activated, the target resource unit is a resource unit indicated by control signaling, and the target resource indication information is associated with a target object.

[0083] In some embodiments, the first resource unit includes a used or active BWP. Determining the target resource indication information includes determining whether the target resource indication information is valid or invalid, and or, determining the scheduling information (e.g., allocated resources) corresponding to the target resource indication information.

[0084] In some embodiments, the target resource indication information may refer to the value corresponding to the first information field (e.g., the FDRA field), or the meaning corresponding to the first information field (e.g., the FDRA field).

[0085] S220, based on the target resource indication information, determine at least one of the following:

[0086] The target resource indication information is valid;

[0087] The target resource indication information is invalid;

[0088] The scheduling information of the target object.

[0089] The resource unit described in this application embodiment may include, but is not limited to, at least one of the following:

[0090] BWP, cell, carrier, frequency resource, resource set, subchannel, resource pool, resource block (RB) set, BWP combination, cell combination, carrier combination, frequency resource combination, resource set combination, subchannel combination, resource pool combination, RB set combination.

[0091] The objects described in the embodiments of this application may include, but are not limited to, at least one of the following:

[0092] BWP, cell, carrier, frequency resource, resource set, subchannel, resource pool, resource block (RB) set, BWP combination, cell combination, carrier combination, frequency resource combination, resource set combination, subchannel combination, resource pool combination, RB set combination, cell set.

[0093] In some embodiments, the first resource unit / target resource unit and the target object are different.

[0094] For example, the first resource unit is the first BWP or the first BWP combination, the target resource unit is the target BWP or the target BWP combination, and the target object is the target cell, or the target cell combination, or the target cell set.

[0095] For example, the first resource element is the first carrier, the target resource element is the target carrier, and the target object is the target BWP or a combination of target BWPs.

[0096] In some embodiments, the first resource unit is also called the source resource unit, for example, the first resource unit is the first BWP, and the first BWP is also called the source BWP.

[0097] In some embodiments, the first resource unit / target resource unit is associated with the target object.

[0098] For example, the first BWP / target BWP is associated with the same cell / cell combination / cell set.

[0099] For example, the first carrier / target carrier may be associated with the same cell / cell combination / cell set.

[0100] In the following example, the first resource unit is the first BWP, the target resource unit is the target BWP, and the target object is the target cell. These can also be replaced with other resource units and other objects, and this application does not limit them.

[0101] It should be understood that the embodiments of this application can be applied to scenarios of multi-cell scheduling (MC-scheduling), or to scenarios of single cell with multiple carriers (Single cell with multiple carriers). For example, an object (e.g., a cell) may contain one or more carriers, or one or more bands, or one or more subbands, or one or more active BWPs.

[0102] In some embodiments, the control signaling may be DCI, RRC signaling, or other higher-layer signaling, such as Media Access Control Element (MAC CE), which is not limited in this application.

[0103] In some embodiments, the target BWP is indicated by a BWP indicator, which may be carried in the control signaling.

[0104] In some embodiments, the scheduling information for the target object may include, but is not limited to, at least one of the following:

[0105] The resources that the target object is scheduled for, whether the target object is scheduled, and whether the scheduling information is valid or invalid.

[0106] Optionally, if the scheduling information is invalid, the target object may be considered not to have been scheduled; or if the scheduling information is valid, the target object may be considered to have been scheduled.

[0107] In some embodiments, invalid target resource indication information can be understood as: the value corresponding to the target resource indication information does not correspond to scheduling information, and / or, the target entity has not been scheduled, and / or, the value of the target resource indication information is invalid.

[0108] In some embodiments, the validity of the target resource indication information can be understood as: the value corresponding to the target resource indication information corresponds to scheduling information, and / or the target entity is scheduled, and / or the value of the target resource indication information is a valid value.

[0109] In some embodiments, target resource indication information can be used to indicate resources on a target object, such as frequency resources, resource sets, RB sets, frequency resource combinations, resource set combinations, or RB set combinations.

[0110] In some embodiments, target resource indication information is determined by interpreting a first information field.

[0111] Optionally, the first information field may be called the resource indication field, or it may be called another name, such as the FDRA field when the resource indication information is used to indicate frequency domain resources.

[0112] In some embodiments, the number of bits in the first information field is determined based on the configuration of the first resource unit.

[0113] In other words, the number of bits in the first information field is equal to the number of bits of resource indication information required by the first resource unit, denoted as M bits.

[0114] In some embodiments, the number of bits of resource indication information required by the target resource unit may be N bits, where N and M may be the same or different.

[0115] In some embodiments, the first information field may be obtained from the first DCI.

[0116] In some embodiments, the terminal may interpret the first information field based on the first resource unit to determine the target resource indication information, or it may interpret the first information field based on the target resource unit to determine the target resource indication information.

[0117] When the terminal interprets the first information field based on the target resource unit, since the number of bits in the first information field is the number of bits of the resource indication information required by the first resource unit, if the number of bits of the resource indication information required by the target resource unit is different from the number of bits of the resource indication information required by the first resource unit, the terminal needs to fill or truncate the first information field, and determine the target resource indication information based on the first information field after filling or truncation.

[0118] For example, if the number of bits of resource indication information required by the target resource unit is greater than the number of bits of resource indication information required by the first resource unit, then the first information field needs to be padded. Based on the padded first information field, the target resource indication information is determined. The padded first information field contains N bits.

[0119] For example, if the number of bits of resource indication information required by the target resource unit is less than the number of bits of resource indication information required by the first resource unit, then the first information field needs to be truncated. The target resource indication information is then determined based on the truncated first information field. Here, the number of bits in the truncated first information field is N. For example, truncating the first MN bits of the first information field means determining the target resource indication information based on the lower N bits.

[0120] In some embodiments, under a first indication scheme (e.g., FDRA-based scheme), the terminal determines scheduling information based on resource indication information; under a second indication scheme (e.g., cell indicator-based scheme), the terminal determines scheduling information based on object indication information (e.g., cell indication information).

[0121] For example, under the first instruction scheme, if the resource instruction information is invalid, it is determined that the target object associated with the resource instruction information has not been scheduled.

[0122] For example, under the second indication scheme, the object indication information can indicate a scheduled object or an unscheduled object.

[0123] However, in some cases (such as the first indication scheme), when the terminal interprets the first information field based on the target resource unit to determine the target resource indication information, the aforementioned problem A may occur. For example, if the number of bits of resource indication information required by the target resource unit is greater than the number of bits of resource indication information required by the first resource unit, the first information field needs to be padded. When determining the target resource indication information based on the padded first information field, the aforementioned problem A may occur.

[0124] In view of this, in some embodiments of this application, the conditions for interpreting the first information domain based on the target resource unit can be constrained, thereby achieving the purpose of avoiding problem A.

[0125] For example, under the first instruction scheme, the first information domain is interpreted based on the first resource unit. Under the second instruction scheme, the first information domain can be interpreted based on the first BWP, or it can be interpreted based on the target BWP, or the first information domain can be ignored and the scheduling information of the target object can be determined based on the object instruction information.

[0126] The following describes, with reference to Example 1, the method for selecting resource units used by the terminal to determine target resource indication information.

[0127] Example 1:

[0128] In some embodiments of this application, S210 may include at least one of the following:

[0129] If the first condition is met, the target resource indication information is determined based on the first information field according to the first resource unit; for example, the FDRA field is interpreted according to the current active BWP configuration, thereby determining whether the target indication information is valid or invalid.

[0130] If the second condition is met, the target resource indication information is determined based on the first information field according to the target resource unit or the first resource unit. For example, based on the configuration of the indicated target BWP, the FDRA field is interpreted to determine whether the target resource indication information is valid or invalid.

[0131] In some embodiments, the first condition includes at least one of the following:

[0132] No object set information is configured;

[0133] No configuration object composition information is provided;

[0134] Configure / activate / be configured using the first instruction scheme.

[0135] In some embodiments, the second condition includes at least one of the following:

[0136] The object set information has been configured.

[0137] Object composition information has been configured;

[0138] Configure / activate / be configured using the second instruction scheme.

[0139] In the embodiments of this application, if it is described as 'Z is configured', it may mean that at least Z is configured or at least one Z is configured, or only Z is configured.

[0140] For example, configuring object set information can mean that at least one object set information is configured, or at least one object set information is configured, or at least one object set information is configured; configuring object combination information can mean that at least one object combination information is configured, or at least one object combination information is configured, or at least one object combination information is configured.

[0141] In the embodiments of this application, Y satisfying X is Z can mean that Y satisfying X includes at least one Z, or only includes Z.

[0142] For example, if the first condition is met, the terminal can determine the target resource indication information based on the first BWP; or, if the second condition is met, the terminal can determine the target resource indication information based on the target BWP or the first BWP.

[0143] Optionally, the object combination information may include a list of scheduled cell combinations, such as ScheduledCellCombo-ListDCI-1-3, ScheduledCellCombo-ListDCI-0-3, and ScheduledCellCombo.

[0144] Optionally, the object set information may include a list of scheduled cell sets, such as ScheduledCellSet-ListDCI-1-3, ScheduledCellSet-ListDCI-0-3 / ScheduledCellSet.

[0145] Optionally, in the absence of configured object set information or configured object combination information, it can be assumed that the terminal is configured / activated / configured using the first indication scheme. Therefore, the terminal can interpret the first information field according to the first BWP to determine the target resource indication information.

[0146] Optionally, when configuring object set information or configuration object combination information, it can be assumed that the terminal is configured / activated / configured using the second indication scheme. Therefore, the terminal can interpret the first information field according to the first BWP or the target BWP to determine the target resource indication information.

[0147] In some scenarios, the aforementioned problem A may occur because, under certain circumstances (where all 1s are considered invalid values), filling in 0s causes invalid resource indication information to become valid resource indication information, thus causing the terminal to be unable to correctly determine the actual scheduling information, or in other words, the terminal and network-side devices have inconsistent understandings of the actual scheduling information.

[0148] In view of this, the filling method of the first information field in the embodiments of this application can be adjusted to avoid the aforementioned problem A.

[0149] The following describes the specific implementation of filling the first information field, in conjunction with Example 2.

[0150] Example 2:

[0151] In some embodiments of this application, the terminal may fill in the first information field, for example, by filling it with 1 or 0, based on the resource allocation type of the target resource unit or the indication scheme configured / activated / configured on the terminal. Further optionally, the terminal may determine the target resource indication information based on the filled first information field.

[0152] For example, when the number of bits of resource indication information required by the target BWP is greater than the number of bits of resource indication information required by the first BWP, or when the bandwidth of the target BWP is greater than the bandwidth of the first BWP, or when the frequency domain resources (e.g., the number of RBs) of the target BWP are greater than the frequency domain resources of the first BWP, the first information field is filled according to the resource allocation type of the target resource unit, or the indication scheme configured / activated / configured on the terminal.

[0153] In some embodiments, Embodiment 2 can be combined with Embodiment 1. For example, when the terminal determines the target resource indication information by interpreting the first information field according to the target BWP according to Embodiment 1, it can determine the filling method of the first information field according to Embodiment 2.

[0154] Example 2-1:

[0155] In some embodiments, the terminal fills the first information field according to the resource allocation type of the target resource unit, or according to the configuration / activation / configuration usage indication scheme on the terminal, including at least one of the following filling methods:

[0156] Filling method 1: If the resource allocation type of the target resource unit is type 0, fill the first information field with 0;

[0157] Filling method 2: If the resource allocation type of the target resource unit is type 1, fill the first information field with 1;

[0158] Filling method 3: If the resource allocation type of the target resource unit is dynamic, fill the first information field with 0 or 1, for example, preferably fill with 0;

[0159] Filling method 4: If the resource allocation type of the target resource unit is type 2 and the SCS of the target resource unit is the first SCS, fill the first information field with 0 or 1, for example, preferably fill with 0;

[0160] Filling method 5: If the resource allocation type of the target resource unit is type 2 and the SCS of the target resource unit is the second SCS, fill the first information field with 1 or 0, for example, preferably fill with 1;

[0161] Filling method 6: If the first condition is met, and the resource allocation type of the target resource unit is type 0, dynamic type, or type 2, and the SCS of the target resource unit is the first SCS, fill the first information field with 0;

[0162] Filling method 7: If the first condition is met, and the resource allocation type of the target resource unit is type 1, dynamic type, or type 2, and the SCS of the target resource unit is the second SCS, fill the first information field with 1;

[0163] Filling method 8: If the second condition is met, fill the first information field with 0.

[0164] The specific implementation of the first and second conditions is described above and will not be repeated here for the sake of brevity.

[0165] In some embodiments, the first SCS can be 30 kHz (or μ = 1), and the second SCS can be 15 kHz (or μ = 0).

[0166] In some embodiments, when the resource allocation type of the target resource unit is type0, dynamic, or type 2 and μ = 1, the first information field being all 0 indicates invalid resource indication information. In this case, when the first information field needs to be padded according to the interpretation of the target BWP (i.e., the number of bits of resource indication information required by the target BWP is greater than the number of bits of resource indication information required by the first BWP, or the bandwidth of the target BWP is greater than the bandwidth of the first BWP, or the frequency domain resources of the target BWP are more than the frequency domain resources of the first BWP), the first information field can be padded with 0. This can avoid the situation where the terminal uses the padding method of filling with 1 when the network-side device indicates invalid resource indication information, causing the invalid resource indication information to become valid resource indication information. However, this resource indication information cannot be actually used for scheduling, resulting in a problem of inconsistent understanding of the actual scheduling information between the network-side device and the terminal.

[0167] In other embodiments, when the resource allocation type of the target resource unit is type1, dynamic, or type2 and μ = 0, the first information field being all 1s indicates invalid resource indication information. In this case, when the first information field needs to be padded according to the interpretation of the target BWP (i.e., the number of bits of resource indication information required by the target BWP is greater than the number of bits of resource indication information required by the first BWP, or the bandwidth of the target BWP is greater than the bandwidth of the first BWP, or the frequency domain resources of the target BWP are more than the frequency domain resources of the first BWP), the first information field can be padded with 1s. This can avoid the situation where the terminal uses the padding method of filling with 0s when the network-side device indicates invalid resource indication information, causing the invalid resource indication information to become valid resource indication information. However, this resource indication information cannot be actually used for scheduling, resulting in a problem of inconsistent understanding of the actual scheduling information between the network-side device and the terminal.

[0168] In some embodiments, when the first condition is met, the terminal determines target resource indication information based on the first information field, and further determines scheduling information based on the target resource indication information. Therefore, the terminal may fill the first information field with 0 when the first condition is met and the resource allocation type of the target resource unit is type0, dynamic, type 2 and μ=1, or fill the first information field with 1 when the first condition is met and the resource allocation type of the target resource unit is type1, dynamic, type 2 and μ=0.

[0169] That is, in the embodiments of this application, the fill value is related to the definition value of the invalid resource indication information.

[0170] For example, when the defined value of invalid resource indication information is all 0, it is filled with 0; when the defined value of invalid resource indication information is all 1, it is filled with 1. This can avoid the problem of invalid resource indication information becoming valid resource indication information due to filling with values ​​that are inconsistent with invalid values, which in turn leads to inconsistent understanding of actual scheduling information by network-side devices and terminals.

[0171] In some embodiments, if the second condition is met, it can be considered that the terminal determines the scheduling information based on the object indication information (i.e., adopts the second indication scheme). In this case, the existing filling scheme does not need to be adjusted. That is, when the first information field needs to be filled according to the interpretation of the target BWP, the first information field can be filled with 0.

[0172] Example 2-2:

[0173] In some embodiments of this application, the terminal may also determine whether to fill in the first information field based on whether the first information field indicates invalid resource indication information.

[0174] For example, if the number of bits of resource indication information required by the target BWP is greater than the number of bits of resource indication information required by the first BWP, or if the bandwidth of the target BWP is greater than the bandwidth of the first BWP, or if the frequency domain resources (e.g., the number of RBs) of the target BWP are greater than the frequency domain resources of the first BWP, the terminal can determine whether to fill the first information field based on whether the first information field indicates invalid resource indication information.

[0175] As an example, if the first information field indicates invalid resource indication information, it is determined that the first information field should not be filled, and / or the target resource indication information is determined based on the first information field.

[0176] When the first information field indicates invalid resource indication information, it can be assumed that the network-side device has no scheduling target object. Therefore, the terminal may choose not to process the first information field, or determine the target resource indication information based on the first information field.

[0177] For example, when the resource allocation type of the target resource unit is type0, dynamic, or type 2 and μ = 1, if the first information field is all 0s, it is determined that the first information field indicates invalid resource indication information. In this case, the first information field may not be processed, and / or the invalid resource indication information may be directly used as the target resource indication information. When further determining the scheduling information based on the target resource indication information, it is determined that the target object has not been scheduled.

[0178] For example, when the resource allocation type of the target resource unit is type1, dynamic, or type2 and μ = 0, if the first information field is all 1s, it is determined that the first information field indicates invalid resource indication information. In this case, even if the number of bits of resource indication information required by the target BWP is greater than the number of bits of resource indication information required by the first BWP, or the bandwidth of the target BWP is greater than the bandwidth of the first BWP, or the frequency domain resources (e.g., the number of RBs) of the target BWP are greater than the frequency domain resources of the first BWP, the terminal may not perform padding processing on the first information field, and / or directly use the invalid resource indication information as the target resource indication information. When further determining scheduling information based on the target resource indication information, it is determined that the target object has not been scheduled.

[0179] As another example, when the first information field indicates valid resource indication information, the first information field is filled with 0 according to the target resource unit, and the target resource indication information is determined according to the filled first information field.

[0180] When the first information field indicates valid resource indication information, it can be determined that the value of the first information field is neither all 0 nor all 1. In this case, the first information field is filled with 0, and then the target resource indication information is determined based on the filled first information field. There is no problem of turning invalid resource indication information into valid resource indication information, thus avoiding the aforementioned problem A.

[0181] For example, when the resource allocation type of the target resource unit is type0, dynamic, or type 2 and μ = 1, if the first information field is not all zeros, it is determined that the first information field indicates valid resource indication information. In this case, the first information field can be filled with zeros. Further optionally, the target resource indication information is determined based on the filled first information field.

[0182] For example, when the resource allocation type of the target resource unit is type1, dynamic, or type2 and μ = 0, if the first information field is not all 1s, it is determined that the first information field indicates valid resource indication information. In this case, even if the number of bits of resource indication information required by the target BWP is greater than the number of bits of resource indication information required by the first BWP, or the bandwidth of the target BWP is greater than the bandwidth of the first BWP, or the frequency domain resources (e.g., the number of RBs) of the target BWP are greater than the frequency domain resources of the first BWP, the terminal can fill the first information field with 0s. Further optionally, the target resource indication information is determined based on the filled first information field.

[0183] In some scenarios, the aforementioned problem A may occur because the network-side device indicates a target resource unit that is different from the current resource unit, and also indicates invalid resource indication information.

[0184] In view of this, embodiments of this application can constrain the indication method of DCI to avoid the aforementioned problem A.

[0185] The indication method of DCI will be described below with reference to Example 3.

[0186] Example 3:

[0187] In this embodiment 3, DCI does not support simultaneously indicating resource units different from the used / activated resource units and invalid resource indication information, or, it is not expected that DCI simultaneously indicates resource units different from the used / activated resource units and invalid resource indication information, thereby avoiding the aforementioned problem A caused by filling the first information field.

[0188] In some embodiments, the first information field and / or the target resource indication information are obtained through a first DCI, the first DCI further including resource unit indication information, the resource unit indication information indicating the target resource unit. Wherein, the first DCI does not support simultaneously indicating a target resource unit different from the first resource unit and invalid resource indication information; or, it is not expected that the first DCI simultaneously indicates a target resource unit different from the first resource unit and invalid resource indication information.

[0189] In some embodiments, the first DCI does not support simultaneously indicating a target resource unit different from the first resource unit and invalid resource indication information, and may refer to:

[0190] For the same object or target object, the first DCI does not support simultaneously indicating a target resource unit different from the first resource unit and invalid resource indication information. For example, the first DCI cannot simultaneously indicate a BWP different from the current BWP to the first cell and also indicate invalid resource indication information to the first cell.

[0191] Optionally, the first DCI can support indicating a BWP different from the current BWP to the second cell, while simultaneously indicating an invalid resource indication message to the first cell.

[0192] Optionally, the target resource pair being different from the first resource unit can mean:

[0193] The number of bits of resource indication information required by the target resource unit is different from the number of bits of resource indication information required by the first resource unit. For example, the number of bits of resource indication information required by the target resource unit is greater than the number of bits of resource indication information required by the first resource unit; or

[0194] The bandwidth of the target resource unit is different from the bandwidth of the first resource unit; for example, the bandwidth of the target resource unit is greater than the bandwidth of the first resource unit.

[0195] The frequency domain resources of the target resource unit are different from those of the first resource unit. For example, the frequency domain resources (e.g., the number of RBs) of the target resource unit are greater than those of the first resource unit.

[0196] Optionally, if the second condition is met, the constraints in Example 3 are not applied to the DCI.

[0197] The second condition includes at least one of the following:

[0198] The object set information has been configured.

[0199] Object composition information has been configured;

[0200] Configure / activate / be configured using the second instruction scheme.

[0201] That is, if the second condition is met, Example 3 is not used.

[0202] Optionally, embodiment 3 may be used if the second condition is not met, or embodiment 3 may be used if the first condition is met.

[0203] In some scenarios, the aforementioned problem A occurs under specific circumstances, such as when the terminal uses the first indication scheme, interprets the first information field according to the target resource unit, adopts a filling method of 0, and the resource allocation type of the target resource unit is type 1 or type 2 and the SCI is the second SCS. Therefore, one design idea is to avoid the aforementioned problem A by constraining the indication scheme configured / activated / used by the terminal.

[0204] It should be understood that the indication scheme in the embodiments of this application can be configured per object, such as per scheduling cell, or it can be configured at other granularities, such as per resource unit, such as per BWP / per BWP combination / BWP indication information per code point. In this way, when a resource unit handover occurs, the terminal can switch to the indication scheme corresponding to the target resource unit, thereby configuring a suitable indication scheme for the target resource unit that may have a problem can solve problem A.

[0205] The following describes the selection of the terminal configuration / activation / usage instruction scheme in conjunction with Example 4.

[0206] Example 4:

[0207] In some embodiments of this application, the method 200 further includes:

[0208] The terminal determines a configuration / activation / use indication scheme and / or a non-configuration / non-activation / non-use indication scheme based on the first information. For example, the configuration / activation / use indication scheme is determined from the first indication scheme and the second indication scheme, and / or a non-configuration / non-activation / non-use indication scheme is determined.

[0209] In some embodiments, the first information includes, but is not limited to, at least one of the following:

[0210] Resource allocation type for at least one resource unit;

[0211] SCS of the at least one resource unit;

[0212] The resource size of the at least one resource unit, such as bandwidth;

[0213] The number of resources in the at least one resource unit, such as the number of RBs, the number of carriers, etc.;

[0214] The number of bits of resource indication information required for the at least one resource unit.

[0215] In some embodiments, the at least one resource unit is a resource unit that can be indicated by control signaling, such as a resource unit that can be scheduled or indicated by DCI, or a resource unit that can be scheduled or indicated by resource unit indication information, wherein the resource unit indication information is used to indicate the resource unit to be scheduled or indicated.

[0216] For example, the at least one resource unit is at least one BWP, which is a BWP that can be indicated by control signaling, such as a BWP that can be scheduled or indicated by DCI, or a BWP that can be scheduled or indicated by BWP indication information.

[0217] In some embodiments, this embodiment 4 can be applied to a specific object, such as a specific cell, a specific combination of cells, or a specific set of cells, or it can be applied to any object or all objects, such as all cells, all combinations of cells, or all sets of cells. Optionally, the specific object can be predefined or indicated by the network-side device.

[0218] Example 4-1:

[0219] In some embodiments, the terminal determines a configuration / activation / use indication scheme and / or a non-configuration / non-activation / non-use indication scheme based on first information, including:

[0220] If the third condition is met, determine that the second instruction scheme is configured / activated / used, and / or determine that the first instruction scheme is not configured / activated / used; and / or

[0221] If the third condition is not met, determine whether to configure / activate / use the first instruction scheme, and / or determine whether to configure / activate / use the second instruction scheme.

[0222] In this embodiment, satisfying the third condition means that when interpreting the first information field according to the target BWP, the first information field needs to be padded. If it is padded with 0, the aforementioned problem A may occur, affecting the interpretation of the actual scheduling information. In this case, a second indication scheme can be configured / activated / used, that is, the scheduling information is determined according to the object indication information. Optionally, in this case, the terminal can ignore the first information field, or ignore the first information field after padding.

[0223] For example, the third condition includes, but is not limited to, at least one of the following:

[0224] The resource allocation type of the at least one resource unit includes type 1, dynamic type and type 2, and the SCS is at least one of the second SCS;

[0225] The bandwidth of the at least one resource unit is greater than the bandwidth of at least one other resource unit, for example, the bandwidth of the at least one resource unit is greater than the bandwidth of all other resource units.

[0226] The frequency domain resources of the at least one resource unit are greater than the frequency domain resources of at least one other resource unit, for example, the frequency domain resources of the at least one resource unit are greater than the frequency domain resources of all other objects;

[0227] The bandwidth or frequency domain resources of the at least one resource unit are different from the bandwidth or frequency domain resources of at least one other resource unit. For example, the bandwidth or frequency domain resources of the at least one resource unit are different from the bandwidth or frequency domain resources of all other resource units.

[0228] The number of bits of resource indication information required by at least one resource unit is greater than the number of bits of resource indication information required by at least one other resource unit. For example, the number of bits of resource indication information required by at least one resource unit is greater than the number of bits of resource indication information required by all other resource units.

[0229] The number of bits of resource indication information required by the at least one resource unit is different from the number of bits of resource indication information required by at least one other resource unit. For example, the number of bits of resource indication information required by the at least one resource unit is different from the number of bits of resource indication information required by all other resource units.

[0230] In some embodiments, the other resource units may refer to resource units configured on the terminal other than the at least one resource unit. Optionally, the at least one resource unit and other resource units are associated with the same object, such as the same cell / cell combination / cell set.

[0231] As a specific example, if the third condition includes that the resource allocation type of the at least one resource unit includes type 1, dynamic type, and type 2, and the SCS is at least one of the second SCS, then:

[0232] When the resource allocation type of the at least one resource unit includes type 1, dynamic type, and type 2, and the SCS is at least one of the second SCS, the terminal determines to configure / activate / use the second indication scheme, and / or determines not to configure / activate / use the first indication scheme; or,

[0233] When the resource allocation type of at least one resource unit does not include type 1, dynamic type and type 2 and the SCS is any of the second SCS, determine to configure / activate / use the first indication scheme, and / or determine not to configure / activate / use the second indication scheme.

[0234] As another specific example, the third condition includes that the resource allocation type of the at least one resource unit includes type 1, dynamic type, and type 2, and the SCS is at least one of the second SCS, and that the number of bits of resource indication information required by the at least one resource unit is greater than the number of bits of resource indication information required by at least one other resource unit, then:

[0235] When the terminal determines to configure / activate / use the second indication scheme, and / or determines not to configure / activate / use the first indication scheme, when the resource allocation type of at least one resource unit includes type 1, dynamic type, and type 2, and the SCS is at least one of the second SCS, and the number of bits of resource indication information required by the at least one resource unit is greater than the number of bits of resource indication information required by other resource units; or,

[0236] When the terminal determines to configure / activate / use the first indication scheme and / or not to configure / activate / use the second indication scheme when the resource allocation type of at least one resource unit is not type 1, dynamic type, or type 2 and the SCS is any of the second SCS, or when the number of bits of resource indication information required by the at least one resource unit is less than the number of bits of resource indication information required by other resource units.

[0237] Example 4-2:

[0238] In some embodiments, the terminal determines a configuration / activation / use indication scheme and / or a non-configuration / non-activation / non-use indication scheme based on first information, including:

[0239] If the fourth condition is met, determine that the first indication scheme is configured / activated / used, and / or determine that the second indication scheme is not configured / activated / used; and / or

[0240] In some embodiments, if the fourth condition is not met, it is determined that the second indication scheme is configured / activated / used, and / or that the first indication scheme is not configured / activated / used.

[0241] In this embodiment of the application, if the fourth condition is met, it can be considered that when interpreting the first information field according to the target BWP, it is not necessary to fill the first information field, or filling 0 does not affect the meaning of the resource indication information, that is, there will be no situation where invalid resource indication information becomes valid resource indication information. Therefore, the terminal can adopt the first indication scheme.

[0242] For example, the fourth condition includes, but is not limited to, at least one of the following:

[0243] The resource allocation type of the at least one resource unit includes type 0, dynamic type and type 2, and the SCS of the target resource unit is at least one of the first SCS.

[0244] The bandwidth or frequency domain resource of the at least one resource unit is equal to the bandwidth or frequency domain resource of at least one other resource unit, for example, the bandwidth or frequency domain resource of the at least one resource unit is equal to the bandwidth or frequency domain resource of all other resource units.

[0245] The number of bits of resource indication information required by the at least one resource unit is equal to the number of bits of resource indication information required by at least one other resource unit. For example, the bandwidth or frequency domain resource of the at least one resource unit is equal to the bandwidth or frequency domain resource of all other resource units.

[0246] As a specific example, if the fourth condition includes the resource allocation type of the at least one resource unit being type 0, dynamic type, or type 2, and the SCS of the target resource unit is at least one of the first SCS, then:

[0247] When the resource allocation type of at least one resource unit includes type 0, dynamic type, or type 2, and the SCS of the target resource unit is at least one of the first SCS, the terminal determines to configure / activate / use a first indication scheme, and / or determines not to configure / activate / use a second indication scheme; or,

[0248] When the resource allocation type of at least one resource unit does not include type 0, dynamic type and type 2 and the SCS of the target resource unit is any of the first SCS, the terminal determines to configure / activate / use the second indication method, and / or determines not to configure / activate / use the first indication scheme.

[0249] As another specific example, if the fourth condition includes the resource allocation type of the at least one resource unit being type 0, dynamic type, or type 2, and the SCS of the target resource unit being at least one of the first SCS, and the number of bits of resource indication information required by the at least one resource unit being equal to the number of bits of resource indication information required by at least one other resource unit, then:

[0250] When the resource allocation type of at least one resource unit includes type 0, dynamic type, or type 2, and the SCS of the target resource unit is at least one of the first SCS, and the number of bits of resource indication information required by the at least one resource unit is equal to the number of bits of resource indication information required by other resource units, the terminal determines to configure / activate / use the first indication scheme, and / or determines not to configure / activate / use the second indication scheme; or,

[0251] When the terminal determines to configure / activate / use the second indication scheme and / or determines not to configure / activate / use the first indication scheme when the resource allocation type of at least one resource unit does not include type 0, dynamic type or type 2 and the SCS of the target resource unit is any of the first SCS, or when the number of bits of resource indication information required by the at least one resource unit is greater than the number of bits of resource indication information required by other resource units.

[0252] In some scenarios, the aforementioned problem A occurs under specific circumstances, such as when the terminal uses the first indication scheme, interprets the first information field according to the target resource unit, adopts a filling method of 0, and the first information field is all 1 to indicate invalid resource indication information. Therefore, one design idea is to avoid the aforementioned problem A by constraining the resource unit configuration on the terminal side.

[0253] The resource unit configuration on the terminal side will be described below with reference to Example 5.

[0254] Example 5:

[0255] In some embodiments, this embodiment 5 can be applied to a specific object, such as a specific cell, a specific combination of cells, or a specific set of cells, or it can be applied to any object or all objects, such as all cells, all combinations of cells, or all sets of cells. Optionally, the specific object can be predefined or indicated by the network-side device.

[0256] Example 5-1:

[0257] In some embodiments, at least one resource unit of the terminal satisfies at least one of the following:

[0258] When the at least one resource unit includes multiple resource units, and the resource allocation type of the multiple resource units is the same, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit switching, that is, either all 0s are considered invalid, or all 1s are considered invalid.

[0259] The resource allocation type of the at least one resource unit is a specific resource allocation type. In this case, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit is switched, that is, either all 0s are considered invalid, or all 1s are considered invalid.

[0260] The resource allocation type of the at least one resource unit includes at least one of dynamic type and type 0. In this case, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit is switched, that is, all 0s are considered invalid.

[0261] The resource allocation type of the at least one resource unit includes dynamic type, type 0 and type 2, and the SCS of the resource unit is at least one of the first SCS. In this case, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit is switched, that is, all 0s are considered invalid.

[0262] The resource allocation type of the at least one resource unit includes at least one of dynamic type and type 1. In this case, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit is switched, that is, all 1s are considered invalid.

[0263] The resource allocation type of the at least one resource unit includes dynamic type, type 1 or type 2, and the SCS of the resource unit is at least one of the second SCS. In this case, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit is switched, that is, all 1s are considered invalid.

[0264] The bandwidth or frequency domain resource of the at least one resource unit is equal to the bandwidth or frequency domain resource of at least one other resource unit. For example, the bandwidth or frequency domain resource of the at least one resource unit is equal to the bandwidth or frequency domain resource of all other resource units. In this case, it can be assumed that the first information field does not need to be filled after the resource unit is switched, so the problem A caused by filling with 0 will not occur.

[0265] The number of bits of resource indication information required by at least one resource unit is equal to the number of bits of resource indication information required by at least one other resource unit. For example, the number of bits of resource indication information required by at least one resource unit is equal to the number of bits of resource indication information required by all other resource units. In this case, it can be assumed that the first information field does not need to be padded after the resource unit is switched, and the problem A caused by padding with 0 will not occur.

[0266] The bandwidth of the at least one resource unit is less than the bandwidth of at least one other resource unit (e.g., the bandwidth of the at least one resource unit is less than the bandwidth of all other resource units), and the other resource units are resource units that cannot be indicated by control signaling. In this case, it can be assumed that the terminal will not switch to the at least one other resource unit. Therefore, even if the bandwidth of the at least one other resource unit is greater than the bandwidth of the at least one resource unit, it is not necessary to fill the first information field according to the at least one other resource unit. Therefore, the problem A caused by filling with 0 will not occur.

[0267] The frequency domain resources of the at least one resource unit are less than the frequency domain resources of at least one other resource unit (e.g., the offset resources of the at least one resource unit are less than the frequency domain resources of all other resource units), and the other resource units are resource units that cannot be indicated by control signaling. In this case, it can be assumed that the terminal will not switch to the at least one other resource unit. Therefore, even if the frequency domain resources of the at least one other resource unit are greater than the frequency domain resources of the at least one resource unit, it is not necessary to fill the first information field according to the at least one other resource unit. Therefore, the problem A caused by filling with 0 will not occur.

[0268] The number of bits of resource indication information required by the at least one resource unit is less than the number of bits of resource indication information required by at least one other resource unit (e.g., the number of bits of resource indication information required by the at least one resource unit is less than the number of bits of resource indication information required by all other resource units), and the other resource units are resource units that cannot be indicated by control signaling. In this case, it can be assumed that the terminal will not switch to the at least one other resource unit. Therefore, even if the number of bits of resource indication information required by the at least one other resource unit is greater than the number of bits of resource indication information required by the at least one resource unit, it is not necessary to fill the first information field according to the at least one other resource unit. Therefore, the problem A caused by filling with 0 will not occur.

[0269] The terminal is not configured with a sleep resource unit or does not support sleep; for example, none of the terminal's resource units are configured with sleep or do not support sleep.

[0270] The terminal is not configured or does not support the enhanced hybrid automatic repeat request response (HARQ-ACK) codebook. For example, none of the terminal's resource units are configured to sleep or do not support the enhanced HARQ-ACK codebook.

[0271] The terminal is not configured or does not support HARQ retransmission; for example, all resource units are not configured or do not support HARQ retransmission.

[0272] The resource allocation type of the at least one resource unit includes one of dynamic type, type 1 and type 2. For example, under the second indication scheme, the terminal determines the scheduling information based on the object indication information, and the aforementioned problems A and B will not occur. Therefore, the resource unit can be configured as any resource allocation type.

[0273] In some embodiments, the frequency domain resources of the at least one resource element being less than the frequency domain resources of at least one other resource element may include, for example, the number of redundancies (RBs) of the at least one resource element being less than the number of RBs of at least one other resource element. The frequency domain resources of the at least one resource element being equal to the frequency domain resources of at least one other resource element may include, for example, the number of RBs of the at least one resource element being equal to the number of RBs of at least one other resource element.

[0274] In some embodiments, the at least one resource unit is a resource unit that can be indicated by control signaling, such as a resource unit that can be scheduled or indicated by DCI, or a resource unit that can be scheduled or indicated by resource unit indication information, wherein the resource unit indication information is used to indicate the resource unit to be scheduled or indicated.

[0275] For example, the at least one resource unit is at least one BWP, which is a BWP that can be indicated by control signaling, such as a BWP that can be scheduled or indicated by DCI, or a BWP that can be scheduled or indicated by BWP indication information.

[0276] In some embodiments, the at least one resource unit is associated with the same object, such as a first object, such as a first cell / first cell combination / first cell set.

[0277] In some embodiments, the other resource units may be resource units other than at least one of the above-described resource units among all resource units associated with the first object.

[0278] In some embodiments, the other resource elements that cannot be indicated by control signaling may refer to:

[0279] The other resource units cannot be scheduled or indicated by DCI, or cannot be indicated or scheduled by resource unit indication information.

[0280] All other resource units mentioned in this application embodiment may refer to: all other resource units other than the at least one resource unit among all resource units associated with the first object (i.e., the object associated with the at least one resource unit), or all resource units associated with the first object that cannot be indicated by control signaling.

[0281] When a resource unit cannot be indicated by control signaling, even if the number of bits of resource indication information required by that resource unit is more than the number of bits of resource indication information required by other resource units, since the terminal cannot switch to that resource unit, there is no need to consider the problem A caused by padding with 0.

[0282] Example 5-2:

[0283] In some embodiments, when configuring / activating / using the second indication scheme, at least one resource unit of the terminal satisfies at least one of the following:

[0284] When the at least one resource unit includes multiple resource units, and the resource allocation type of the multiple resource units is the same, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit switching, that is, either all 0s are considered invalid, or all 1s are considered invalid.

[0285] The resource allocation type of the at least one resource unit is a specific resource allocation type. In this case, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit is switched, that is, either all 0s are considered invalid, or all 1s are considered invalid.

[0286] The resource allocation type of the at least one resource unit includes at least one of dynamic type and type 0. In this case, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit is switched, that is, all 0s are considered invalid.

[0287] The resource allocation type of the at least one resource unit includes dynamic type, type 0 and type 2, and the SCS of the resource unit is at least one of the first SCS. In this case, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit is switched, that is, all 0s are considered invalid.

[0288] The resource allocation type of the at least one resource unit includes at least one of dynamic type and type 1. In this case, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit is switched, that is, all 1s are considered invalid.

[0289] The resource allocation type of the at least one resource unit includes dynamic type, type 1 or type 2, and the SCS of the resource unit is at least one of the second SCS. In this case, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit is switched, that is, all 1s are considered invalid.

[0290] If the bandwidth or frequency domain resource of at least one resource unit is equal to the bandwidth or frequency domain resource of at least one other resource unit, it can be assumed that the first information domain does not need to be filled after the resource unit is switched, so the problem A caused by filling with 0 will not occur.

[0291] The number of bits of resource indication information required by at least one resource unit is equal to the number of bits of resource indication information required by at least one other resource unit (for example, the number of bits of resource indication information required by at least one resource unit is equal to the number of bits of resource indication information required by all other resource units). In this case, it can be assumed that the first information field does not need to be filled after the resource unit is switched, so the problem A caused by filling with 0 will not occur.

[0292] If the bandwidth of the at least one resource unit is less than the bandwidth of at least one other resource unit (e.g., the bandwidth of the at least one resource unit is less than the bandwidth of all other resource units), and the other resource units are resource units that cannot be indicated by control signaling, then it can be assumed that the terminal will not switch to the at least one other resource unit. Therefore, even if the bandwidth of the at least one other resource unit is greater than the bandwidth of the at least one resource unit, it is not necessary to fill the first information field according to the at least one other resource unit. Therefore, the problem A caused by filling with 0 will not occur.

[0293] If the frequency domain resources of the at least one resource unit are less than the frequency domain resources of at least one other resource unit (e.g., the frequency domain resources of the at least one resource unit are less than the frequency domain resources of all other resource units), and the other resource units are resource units that cannot be indicated by control signaling, then it can be assumed that the terminal will not switch to the at least one other resource unit. Therefore, even if the frequency domain resources of the at least one other resource unit are greater than the frequency domain resources of the at least one resource unit, it is not necessary to fill the first information field according to the at least one other resource unit. Therefore, the problem A caused by filling with 0 will not occur.

[0294] If the number of bits of resource indication information required by the at least one resource unit is less than the number of bits of resource indication information required by at least one other resource unit (for example, the number of bits of resource indication information required by the at least one resource unit is less than the number of bits of resource indication information required by all other resource units), and the other resource units are resource units that cannot be indicated by control signaling, then it can be assumed that the terminal will not switch to the at least one other resource unit. Therefore, even if the number of bits of resource indication information required by the at least one other resource unit is greater than the number of bits of resource indication information required by the at least one resource unit, it is not necessary to fill the first information field according to the at least one other resource unit. Therefore, the problem A caused by filling with 0 will not occur.

[0295] The terminal is not configured with a sleep resource unit or does not support sleep; for example, none of the terminal's resource units are configured with sleep or do not support sleep.

[0296] The terminal is not configured or does not support the enhanced hybrid automatic repeat request response (HARQ-ACK) codebook. For example, none of the terminal's resource units are configured to sleep or do not support the enhanced HARQ-ACK codebook.

[0297] The terminal is not configured or does not support HARQ retransmission; for example, all resource units are not configured or do not support HARQ retransmission.

[0298] The resource allocation type of the at least one resource unit includes one of dynamic type, type 1 and type 2. For example, under the second indication scheme, the terminal determines the scheduling information based on the object indication information. In this case, the resource unit can be configured as any resource allocation type.

[0299] In embodiments 5-1 and 5-2, the resource allocation type of the at least one resource unit is the same, including at least one of the following:

[0300] The resource allocation type of each of the at least one resource unit is type 0;

[0301] The resource allocation type of each of the at least one resource unit is type 1;

[0302] The resource allocation type of the at least one resource unit is type 2, and the SCS of the resource unit is the first SCS;

[0303] The resource allocation type of the at least one resource unit is type 2, and the SCS of the resource unit is the second SCS;

[0304] The resource allocation type of at least one resource unit is dynamic.

[0305] In embodiments 5-1 and 5-2, the specific resource allocation type may include at least one of the following:

[0306] Type 0;

[0307] Type 1;

[0308] Type 2, and the SCS of the resource unit is the first SCS;

[0309] Type 2, and the SCS of the resource unit is the second SCS;

[0310] Dynamic type.

[0311] Example 5-3:

[0312] In some embodiments, when configuring / activating / using the first indication scheme, at least one resource unit of the terminal satisfies at least one of the following:

[0313] When the at least one resource unit includes multiple resource units, and the resource allocation type of the multiple resource units is the same, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit switching, that is, all 1s or all 0s are considered invalid.

[0314] The resource allocation type of the at least one resource unit is a specific resource allocation type. In this case, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit is switched, that is, all 1s or all 0s are considered invalid.

[0315] The resource allocation type of the at least one resource unit includes at least one of dynamic type and type 0. In this case, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit is switched, that is, all 0s are considered invalid.

[0316] The resource allocation type of the at least one resource unit includes dynamic type, type 0 or type 2, and the SCS of the resource unit is at least one of the first SCS. In this case, it can be considered that the method of identifying invalid resource indication information is the same before and after the resource unit is switched, that is, all 0s are considered invalid.

[0317] If the bandwidth or frequency domain resource of at least one resource unit is equal to the bandwidth or frequency domain resource of at least one other resource unit (e.g., the bandwidth or frequency domain resource of at least one resource unit is equal to the bandwidth or frequency domain resource of all other resource units), then it can be assumed that the first information domain is not filled after the resource unit is switched, and the problem A caused by filling with 0 will not occur.

[0318] The number of bits of resource indication information required by at least one resource unit is equal to the number of bits of resource indication information required by at least one other resource unit (for example, the number of bits of resource indication information required by at least one resource unit is equal to the number of bits of resource indication information required by all other resource units). In this case, it can be assumed that the first information field does not need to be filled after the resource unit is switched, and the problem A caused by filling with 0 will not occur.

[0319] If the bandwidth of the at least one resource unit is less than the bandwidth of at least one other resource unit (e.g., the bandwidth of the at least one resource unit is less than the bandwidth of all other resource units), and the other resource units are resource units that cannot be indicated by control signaling, then it can be assumed that the terminal will not switch to the at least one other resource unit. Therefore, even if the bandwidth of the at least one other resource unit is greater than the bandwidth of the at least one resource unit, it is not necessary to fill the first information field according to the at least one other resource unit. Therefore, the problem A caused by filling with 0 will not occur.

[0320] If the frequency domain resources of the at least one resource unit are less than the frequency domain resources of at least one other resource unit (e.g., the frequency domain resources of the at least one resource unit are less than the frequency domain resources of all other resource units), and the other resource units are resource units that cannot be indicated by control signaling, then it can be assumed that the terminal will not switch to the at least one other resource unit. Therefore, even if the frequency domain resources of the at least one other resource unit are more than the frequency domain resources of the at least one resource unit, it is not necessary to fill the first information field according to the at least one other resource unit. Therefore, the problem A caused by filling with 0 will not occur.

[0321] If the number of bits of resource indication information required by at least one resource unit is less than the number of bits of resource indication information required by at least one other resource unit (e.g., the number of bits of resource indication information required by at least one resource unit is less than the number of bits of resource indication information required by all other resource units), and the other resource units are resource units that cannot be indicated by control signaling, then it can be assumed that the terminal will not switch to the at least one other resource unit. Therefore, even if the number of bits of resource indication information required by the at least one other resource unit is greater than the number of bits of resource indication information required by the at least one resource unit, it is not necessary to fill the first information field according to the at least one other resource unit. Therefore, the problem A caused by filling with 0 will not occur.

[0322] The terminal is not configured with a sleep resource unit or does not support sleep; for example, none of the terminal's resource units are configured with sleep or do not support sleep.

[0323] The terminal is not configured or does not support the enhanced hybrid automatic repeat request response (HARQ-ACK) codebook. For example, none of the terminal's resource units are configured to sleep or do not support the enhanced HARQ-ACK codebook.

[0324] The terminal is not configured or does not support HARQ retransmission; for example, all resource units are not configured or do not support HARQ retransmission.

[0325] In this embodiment 5-3, the resource allocation type of the at least one resource unit is the same, including at least one of the following:

[0326] The resource allocation type of each of the at least one resource unit is type 0;

[0327] The resource allocation type of the at least one resource unit is type 2, and the SCS of the resource unit is the first SCS;

[0328] The resource allocation type of at least one resource unit is dynamic.

[0329] In this embodiment 5-3, the specific resource allocation type may include at least one of the following:

[0330] Type 0;

[0331] Type 2, and the SCS of the resource unit is the first SCS;

[0332] Dynamic type.

[0333] In some scenarios, the aforementioned problem A occurs under specific circumstances, such as when the terminal uses the first indication scheme, interprets the first information field according to the target resource unit, adopts a filling method of 0, and the first information field is all 1 to indicate invalid resource indication information. Therefore, one design idea is to avoid the aforementioned problem A by constraining the resource unit switching method on the terminal side.

[0334] The following describes the resource unit switching transmission on the terminal side in conjunction with Embodiment 6.

[0335] Example 6:

[0336] In this embodiment 6, by constraining the switching of resource units, the aforementioned problem A will not occur when interpreting the first information domain based on the switched resource units.

[0337] In some embodiments, the target resource unit (i.e., the switched resource unit) is not a specific resource unit, or the target resource unit is a resource unit other than a specific resource unit. That is, the network-side device does not instruct the terminal to switch to a specific resource unit, or the terminal does not expect to switch to a specific resource unit. When the target resource unit is a specific resource unit, i.e., when the terminal switches to a specific resource unit, if the first information field is interpreted according to the specific resource unit and filled with 0, the aforementioned problem A will occur. Therefore, by constraining the terminal to not switch to the specific resource unit when switching resource units, the aforementioned problem A can be avoided.

[0338] For example, the specific resource unit satisfies at least one of the following:

[0339] The specific resource unit is a resource unit with a specific identifier (e.g., ID is 0);

[0340] Initial resource unit, such as initial BWP;

[0341] The resource allocation type for the specific resource unit is type 1;

[0342] The resource allocation type of the specific resource unit is type 2, and the SCS of the specific resource unit is the second SCS;

[0343] The bandwidth of the specific resource unit is greater than the bandwidth of at least one other resource unit;

[0344] The frequency domain resources of the specific resource unit are greater than the frequency domain resources of at least one other resource unit;

[0345] The bandwidth or frequency domain resources of the specific resource unit are different from the bandwidth or frequency domain resources of at least one other resource unit;

[0346] The number of bits of resource indication information required by the specific resource unit is greater than the number of bits of resource indication information required by at least one other resource unit;

[0347] The number of bits of resource indication information required by a particular resource unit is different from the number of bits of resource indication information required by at least one other resource unit.

[0348] In the above embodiments 3 to 6, the filling method of the first information field does not need to be adjusted. The existing filling method, i.e., filling with 0, can be used. Only the terminal side indication scheme, DCI indication, resource unit configuration, and resource unit switching method are constrained to avoid the aforementioned problem A.

[0349] It should be understood that the above embodiments 1 to 6 can be implemented individually or in combination, and this application does not limit this. For example, the terminal can select the resource unit used to determine the target resource indication information based on embodiment 1, while combining the constraints of at least one of embodiments 3 to 6 to avoid the aforementioned problem A.

[0350] As an example, the terminal may determine the target resource indication information based on the target resource unit according to Embodiment 1, and at the same time, it may constrain the resource unit configuration of the terminal to meet the constraint conditions in Embodiment 5, or constrain the resource unit switching method of the terminal to meet the constraint conditions in Embodiment 6, etc.

[0351] Example 7: The terminal interprets the first information domain based on the interpretation information to determine the target resource indication information.

[0352] In some embodiments of this application, the method 900 further includes:

[0353] Obtain the interpretation information of the first information domain;

[0354] Based on the interpretation information of the first information domain, the first information domain is interpreted to obtain the target resource indication information.

[0355] In some embodiments, the interpretation information of the first information field is indicated by the network-side device, such as through DCI, RRC signaling, or MAC C signaling, and this application does not limit this.

[0356] In some embodiments, the interpretation information of the first information field is used to indicate at least one of the following:

[0357] The value of the first information field corresponding to invalid resource indication information;

[0358] The first information field indicates invalid resource indication information;

[0359] The first information field is used to indicate valid or invalid resource indication information;

[0360] The padding value used to fill the first information field;

[0361] The method of interpreting the first information domain.

[0362] For example, this interpretation information can indicate that when the first information field after filling takes a specific value (e.g., 1100), it represents invalid resource indication information. Thus, when the first information field takes a value of 11, if it is determined that 00 needs to be filled according to the target resource unit, the first information field after filling will take a value of 1100, which can represent invalid resource indication information, and the aforementioned problem B will not occur.

[0363] In some embodiments, the interpretation information of the first information field may include first indication information (e.g., 1 bit). Different values ​​of the first indication information can be used to indicate whether the first information field indicates valid or invalid resource indication information. For example, a value of 1 indicates that the first information field indicates valid resource indication information, and a value of 0 indicates that the first information field indicates invalid resource indication information. Alternatively, the opposite can be used. In this case, it is not necessary to determine whether the first information field indicates invalid resource indication information based on the value of the first information field.

[0364] In other embodiments, the presence or absence of second indication information in the interpreted information of the first information field can indicate whether the first information field indicates invalid resource indication information. Optionally, the second indication information can be 1 bit. For example, if the second indication information is included, it indicates that the first information field indicates invalid resource indication information; otherwise, it indicates that the first information field indicates valid resource indication information. Alternatively, the reverse can also be true. In this case, it is not necessary to determine whether the first information field indicates invalid resource indication information based on its value.

[0365] In some embodiments, the interpretation information of the first information field may include third indication information, used to indicate the padding value used to pad the first information field, such as indicating padding with 0 or padding with 1. Optionally, the third indication information may be 1 bit. For example, the 1 bit with a value of 1 indicates padding with 0, and a value of 0 indicates padding with 1, or vice versa. For example, when the resource allocation type of the target resource unit is type 0, dynamic type, or type 2 and the SCS is the first SCS, it indicates padding with 0; when the resource allocation type of the target resource unit is type 1, dynamic type, or type 2 and the SCS is the second SCS, it indicates padding with 1.

[0366] In some embodiments, the interpretation method of the first information field may include fourth indication information, used to indicate that the target resource indication information is obtained by filling the first information field with 0 or 1. Optionally, the fourth indication information may be 1 bit. For example, a value of 1 indicates that the target resource indication information is obtained by filling the first information field with 0, a value of 0 indicates that the target resource indication information is obtained by filling the first information field with 1, or vice versa. For example, when the resource allocation type of the target resource unit is type 0, dynamic type, or type 2 and the SCS is the first SCS, it indicates that the target resource indication information is obtained by filling the first information field with 0; when the resource allocation type of the target resource unit is type 1, dynamic type, or type 2 and the SCS is the second SCS, it indicates that the target resource indication information is obtained by filling the first information field with 1.

[0367] In some embodiments, the interpretation information of the first information field is obtained through at least one information field in the second DCI. Optionally, the at least one information field may be an existing information field in the second DCI, or it may be a newly added information field.

[0368] As an example, this interpretation information can be indicated through the New Data Indicator (NDI) field in the second DCI.

[0369] For example, an NDI field value of 1 or 0 indicates that the first information field indicates valid or invalid resource indication information, respectively. Another example is that an NDI field value of 1 or 0 indicates filling with 1 or filling with 0, respectively. Yet another example is that an NDI field value of 1 or 0 indicates that the target resource indication information is obtained by filling the first information field with 1 or by filling the first information field with 0, or vice versa.

[0370] For example, NDI flipping or not flipping indicates that the first information field indicates valid or invalid resource indication information, respectively. For example, NDI flipping or not flipping indicates filling with 1 or filling with 0, respectively. For example, NDI flipping or not flipping indicates that the target resource indication information is obtained by filling the first information field with 1 or by filling the first information field with 0, or vice versa.

[0371] In some implementations, the interpretation information is indicated by at least a portion (e.g., all bits) of an information field. For example, all bits of the NDI field are used to indicate the interpretation information, or a portion of the redundant version (RV) field is used.

[0372] In other implementations, the interpretation information is jointly indicated by at least a portion of bits from at least one second information field and at least a portion of bits from at least one third information field. Alternatively, the interpretation information is indicated by jointly encoding at least a portion of bits from at least one second information field and at least a portion of bits from at least one third information field. The second and third information fields can be existing information fields in the DCI, or they can be newly added information fields, wherein the second and third information fields are different information fields.

[0373] In some embodiments, the second DCI and the first DCI (i.e., the DCI carrying the first information field) are the same DCI, or they may be different DCIs, which is not limited in this application.

[0374] In some embodiments, the second DCI is a DCI that acquires the target resource indication information.

[0375] In other embodiments, the second DCI is a DCI carrying resource unit indication information, wherein the resource unit indication information is used to indicate the target resource unit.

[0376] In some other embodiments, the second DCI is a DCI that indicates or triggers at least one object to perform a resource unit switch and the resource indication information corresponding to the at least one object is invalid.

[0377] Example 8:

[0378] In this embodiment 8, the terminal can first interpret the first information field based on the first resource unit, and then determine whether to fill the first information field according to the interpreted resource indication information, or in other words, determine whether to obtain the target resource indication information according to the target resource unit according to the interpreted resource indication information.

[0379] For example, firstly, the first information field is interpreted according to the first resource unit. If the first information field indicates valid resource indication information, the first information field is filled or truncated according to the target resource unit, and the target resource indication information is determined according to the filled or truncated first information field.

[0380] For example, the first information field is first interpreted according to the first resource unit. If the first information field indicates invalid resource indication information, the first information field is not processed (or, the first information field is not padded or truncated according to the target resource unit). Alternatively, the first information field is padded or truncated according to the target resource unit, but the scheduling information is not determined based on the padded or truncated first information field, or the padded or truncated first information field is ignored.

[0381] In some embodiments of this application, determining that the target resource indication information is invalid based on the target resource indication information includes, but is not limited to, at least one of the following:

[0382] Method 1: When the target resource indication information is a specific value (e.g., all 0s, all 1s, or other values), the target resource indication information is determined to be invalid;

[0383] Method 2: When the resource allocation type of the target resource unit is type 0, dynamic type or type 2 and the SCS of the target resource unit is the first SCS, and all N bits of the target resource indication information are 0, the target resource indication information is determined to be invalid;

[0384] Method 3: When the resource allocation type of the target resource unit is type 0, dynamic type or type 2, and the SCS of the target resource unit is the first SCS, and all N bits of the target resource indication information are 1, the target resource indication information is determined to be invalid, wherein the N bits are obtained by padding with 1;

[0385] Method 4: When the resource allocation type of the target resource unit is type 1, dynamic type or type 2 and the SCS of the target resource unit is the second SCS, and all N bits of the target resource indication information are 1, the target resource indication information is determined to be invalid, wherein the N bits are obtained by padding with 1;

[0386] Method 5: When the resource allocation type of the target resource unit is type 1, dynamic type or type 2 and the SCS of the target resource unit is the second SCS, and all N bits of the target resource indication information are 0, the target resource indication information is determined to be invalid.

[0387] Method 6: When the resource allocation type of the target resource unit is type 1, dynamic type or type 2 and the SCS of the target resource unit is the second SCS, and when M bits out of the N bits of the target resource indication information are all 0, the target resource indication information is determined to be invalid.

[0388] Method 7: When the resource allocation type of the target resource unit is type 1, dynamic type or type 2 and the SCS of the target resource unit is the second SCS, and when M bits out of the N bits of the target resource indication information are all 1, the target resource indication information is determined to be invalid.

[0389] In some embodiments, if the target resource indication information is invalid, the terminal determines that the target object has not been scheduled, and / or the value corresponding to the target resource indication information does not correspond to the scheduling information.

[0390] In some embodiments, the number of bits of resource indication information required by the first resource unit is M bits, and the number of bits of resource indication information required by the target resource unit is N bits. If N is greater than M, when interpreting the first information field according to the target resource unit, the first information field can be filled with 0 or 1 to obtain N bits, and the target resource indication information is the N bits obtained by filling.

[0391] It should be understood that the method for determining the invalidity of the aforementioned resource indication information can be combined with the filling method of the aforementioned first information field.

[0392] For methods 2 and 5, the N bits of the target resource indication information can be obtained by padding with 0s.

[0393] For methods 6 and 7, M bits out of the N bits of the target resource indication information can be M bits of the first information field, excluding padding bits. Therefore, methods 6 and 7 are equivalent to determining the target resource indication information based on the first resource unit. For example, for the resource allocation type in method 6, when the first information field is all 0s, it indicates that the target resource indication information is invalid; or, for the resource allocation type in method 7, when the first information field is all 1s, it indicates that the target resource indication information is invalid.

[0394] Optionally, for method 7, the M bits are the lower M bits out of the N bits, and the higher NM bits can be 0; or, the M bits are the higher M bits out of the N bits, and the lower NM bits can be 0.

[0395] In summary, the terminal can determine the target resource indication information based on the currently used / activated resource unit or target resource unit, and further determine the scheduling information of the target object based on the target resource indication information.

[0396] In some implementations, the terminal can obtain target resource indication information based on the first resource unit when the first condition is met, or obtain target resource indication information based on the target resource unit or the first resource unit when the second condition is met. This helps to ensure the correctness of the target resource indication information determined by the terminal and ensures that the terminal and network-side equipment have a consistent understanding of the actual scheduling information.

[0397] In some implementations, the terminal can adjust the filling method of the first information field that may cause problems. This allows the terminal to fill the first information field with an appropriate filling method, which helps to ensure the correctness of the target resource indication information determined by the terminal and ensures that the terminal and network-side devices have a consistent understanding of the actual scheduling information.

[0398] In some implementations, the terminal can constrain the indication method of the DCI indicating resource units and resource indication information, that is, constrain the DCI to not support simultaneously indicating target resource units different from the first resource unit and invalid resource indication information, thereby ensuring the correctness of the target resource indication information determined by the terminal based on the target resource unit and ensuring that the terminal and network-side devices have a consistent understanding of the actual scheduling information.

[0399] In some implementations, constraints can be imposed on the configuration / activation / use indication schemes in situations where problems may occur, thereby ensuring the correctness of the target resource indication information determined by the terminal based on the target resource unit and ensuring that the terminal and network-side devices have a consistent understanding of the actual scheduling information.

[0400] In some implementations, constraints can be imposed on the configuration of resource units on the terminal side, thereby ensuring the correctness of the target resource indication information determined by the terminal based on the target resource unit, and ensuring that the terminal and network-side devices have a consistent understanding of the actual scheduling information.

[0401] In some implementations, constraints can be imposed on the resource unit switching method on the terminal side, thereby ensuring the correctness of the target resource indication information determined by the terminal based on the target resource unit, and ensuring that the terminal and network-side devices have a consistent understanding of the actual scheduling information.

[0402] In some implementations, the terminal can interpret the first information field based on additional interpretation information to determine the target resource indication information, thereby ensuring the correctness of the target resource indication information determined by the terminal and ensuring that the terminal and network-side devices have a consistent understanding of the actual scheduling information.
