It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0040] In a communication system, a network-side device may schedule a physical uplink shared channel (PUSCH) or a physical downlink shared channel (PDSCH) through downlink control information (DCI).

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

[0042] In some scenarios, the communication system may support the following frameworks:

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

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

[0045] One mc-DCI can schedule / indicate one cell combination at a time.

[0046] There are two methods for mc-DCI to schedule / indicate a cell combination:

[0047] Method 1: Cell indicator based scheme

[0048] For example, Radio Resource Control (RRC) configures a cell combination table for each cell set. Each cell combination table corresponds to an index, and the mc-DCI carries a field to indicate an index. For example, if '01' corresponds to cell 1 / 3, then if the mc-DCI indicates '01', it means that cell 1 / 3 is scheduled / indicated, and 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 field of cell1 / 2 / 3 / 4. If the FDRA field corresponding to a cell indicates an invalid value, it means that the cell is not scheduled.

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

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

[0053] In some scenarios, each reference cell or cell set or each cell has a corresponding DCI number limit / scheduling number limit.

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

[0055] For another example, in a monitoring occasion, there are at most N2 single-cell scheduling DCIs (sc-DCIs) for a cell in the cell set (which can schedule the cell).

[0056] When counting the downlink assignment index (DAI), if a cell combination is scheduled, the DAI is counted for the cell with a specific ID (minimum cell ID) in the cell combination (for example, DAI plus one), or the DAI is counted based on the cell with a specific ID (minimum ID) in the cell combination to generate a Hybrid Automatic Repeat request Acknowledgement (HARQ-ACK bit).

[0057] Here, we can think of the DAI count as being associated with the DAI count of the cell with a specific ID (minimum cell ID) in the cell combination.

[0058] When generating HARQ-ACK bits, the cell set dimension is traversed, and each cell in the cell set is traversed, thereby 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 (the smallest cell ID) in the cell combination. For cells that have not been scheduled, a corresponding negative acknowledgment (NACK) is generated.

[0059] In some cases, mc-DCI can carry dormancy indication information. There are two specific ways to carry it:

[0060] Method 1: Carrying an explicit dormancy indication field;

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

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

[0063] For example, if the terminal is on BWP A, but the BWP indicator in the DCI indicates BWP B, the terminal needs to switch from BWP A to BWP B. However, the number of bits in the information field in this DCI is still determined by the configuration of BWP A. For example, the number of bits in the FDRA field is still determined by the resource allocation type and bandwidth of BWP A. However, when interpreting the FDRA field, 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 corresponding to the BWP B configuration is less than the number of bits M in the FDRA field in the DCI, the terminal can interpret it based only on the lowest N bits to obtain the actual frequency domain allocation information; it can also be interpreted as truncating the first MN bits of the FDRA field and interpreting it based on the remaining N bits to obtain the actual frequency domain allocation information.

[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 in the DCI, the terminal will fill NM zeros before the M bits, interpret the N bits obtained after filling, and obtain the actual frequency domain allocation information.

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

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

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

[0069] For the dynamic switching resource allocation type (denoted as dynamic), the FDRA field is set to all 1s or all 0s as invalid values;

[0070] For resource allocation type 2 (denoted as type2), and SCS is 30kHz (i.e., μ=1), the FDRA field is set to all 0s as an invalid value;

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

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

[0073] In some scenarios, if it is known that the FDRA field corresponding to some cells is invalid, at least part of the information field corresponding to the cell has two functions in the mc-DCI:

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

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

[0076] To facilitate understanding of the embodiments of the present application, the technical issues of the present application are explained.

[0077] Problem A: In the prior art, if the mc-DCI triggers a BWP switch, and the number of FDRA bits required for the BWP indicated by the BWP indicator is greater than the number of FDRA bits required for the current BWP, the terminal will fill the FDRA field with 0s and interpret the information according to the FDRA field after filling it with 0s. 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, after filling the FDRA field with 0s, the resulting FDRA field will definitely not be all "1s", and thus the resulting FDRA field will definitely not indicate an invalid value. In this case, it is impossible to determine that the cell is actually not scheduled through the indication of the FDRA field, that is, this method cannot indicate an invalid value.

[0078] Issue B: If the FDRA field is modified to interpret the current BWP, if the FDRA field is an invalid FDRA, this means that the FDRA obtained by truncating or padding the invalid FDRA with zeros 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 needs to be padded with two zeros, resulting in an FDRA of 0011. This is valid scheduling information for the BWP indicated by the BWP indicator, but it cannot be actually used for scheduling.

[0079] Therefore, when a resource unit (eg, BWP) of a terminal is switched, how to determine the scheduling information of an object (eg, a cell) of the terminal is an issue that needs to be solved urgently.

[0080] The wireless communication method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0081] FIG2 is a schematic diagram of a wireless communication method provided in an embodiment of the present application. As shown in FIG2 , the method 200 includes at least part of 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 used or activated resource unit, the target resource unit is a resource unit indicated by control signaling, and the target resource indication information is associated with the 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 scheduling information (eg, allocated resources) corresponding to the target resource indication information.

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

[0085] S220: Determine at least one of the following according to the target resource indication information:

[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 the embodiments of the present application 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 (RB set), BWP combination (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 the present 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 (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 a first BWP or a first BWP combination, the target resource unit is a target BWP or a target BWP combination, and the target object is a target cell, a target cell combination, or a target cell set.

[0095] For another example, the first resource unit is a first carrier, the target resource unit is a target carrier, and the target object is a target BWP or a target BWP combination.

[0096] In some embodiments, the first resource unit is also called a source resource unit. For example, the first resource unit is a first BWP. The first BWP is also called a source BWP.

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

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

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

[0100] In the following examples, 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 may also be replaced with other resource units and other objects, which are not limited in this application.

[0101] It should be understood that the embodiments of the present application can be applicable to multi-cell scheduling (mc-scheduling) scenarios, or can also be applicable to single-cell scheduling (single cell with multiple carrier) scenarios with multiple carriers, for example, an object (such as a cell) simultaneously contains one or more carriers, or one or more frequency bands (band), or one or more subbands (subband), or one or more activated BWPs.

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

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

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

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

[0106] Optionally, when the scheduling information is invalid, it can be considered that the target object is not scheduled, or when the scheduling information is valid, it can be considered that the target object is scheduled.

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

[0108] In some embodiments, the target resource indication information being valid 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, the target resource indication information may be used to indicate resources on the target object, such as frequency resources, resource sets, RB sets, frequency resource combinations, resource set combinations, or RB set combinations.

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

[0111] Optionally, the first information field is also called a resource indication field, or may be other names. For example, when the resource indication information is used to indicate frequency domain resources, the first information field is also called an FDRA field.

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

[0113] In other words, the number of bits of the first information field is equal to the number of bits of the resource indication information required by the first resource unit, which is recorded 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 may also 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 of 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, the first information field needs to be padded, and the target resource indication information is determined based on the padded first information field, where the number of bits of the padded first information field is N bits.

[0119] For another 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, the first information field needs to be truncated, and the target resource indication information is determined based on the truncated first information field. The number of bits of the truncated first information field is N. For example, the first MN bits of the first information field are truncated, that is, the target resource indication information is determined 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 indication scheme, if the resource indication information is an invalid value, it is determined that the target object associated with the resource indication information is not scheduled.

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

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

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

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

[0126] The following describes, in conjunction with Example 1, a method for selecting a resource unit used by a terminal to determine target resource indication information.

[0127] Example 1:

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

[0129] When 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 configuration of the current activated BWP to determine whether the target indication information is valid or invalid.

[0130] When 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, the FDRA field is interpreted according to the configuration of the indicated target BWP 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] There is no configuration object set information;

[0133] No configuration object combination information;

[0134] Configure / activate / be configured to use the first indication scheme.

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

[0136] Configured object set information;

[0137] Object combination information is configured;

[0138] Configure / activate / be configured to use the second indication scheme.

[0139] In the embodiment of the present 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 may mean configuring at least object set information, or at least one object set information, or configuring only one object set information; configuring object combination information may mean configuring at least object combination information, or configuring at least one object combination information, or configuring only one object combination information.

[0141] In the embodiment of the present application, Y satisfying X is Z may mean that Y satisfying X includes at least one Z, or only includes Z.

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

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

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

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

[0147] In some scenarios, the aforementioned problem A may occur because in some cases (all 1s are considered invalid values) 0 is filled in, causing invalid resource indication information to become valid resource indication information, thereby causing the terminal to be unable to correctly determine the actual scheduling information, or in other words, the terminal and the network side device have inconsistent understandings of the actual scheduling information.

[0148] In view of this, the embodiment of the present application can adjust the filling method of the first information field 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 the present application, the terminal may fill the first information field with 1 or 0, for example, based on the resource allocation type of the target resource unit, or an indication scheme configured / activated / configured for use 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 the bandwidth of the target BWP is greater than the bandwidth of the first BWP, or the frequency domain resources (such as the number of RBs) of the target BWP are more 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 for use on the terminal.

[0153] In some embodiments, this embodiment 2 can be combined with embodiment 1. For example, when the terminal determines to interpret the first information field according to the target BWP to determine the target resource indication information 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 the indication scheme configured / activated / configured for use 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 mode 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 0;

[0159] Filling mode 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 mode 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 mode 6: If the first condition is met, and the resource allocation type of the target resource unit is type 0, dynamic type, type 2, and the SCS of the target resource unit is the first SCS, fill the first information field with 0;

[0162] Filling mode 7: When the first condition is met, and the resource allocation type of the target resource unit is type 1, dynamic type, 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 may be 30 kHz (or μ=1) and the second SCS may be 15 kHz (or μ=0).

[0166] In some embodiments, when the resource allocation type of the target resource unit is type0, dynamic, type 2 and μ=1, the first information field is all 0s, indicating invalid resource indication information. In this case, when the first information field is interpreted according to the target BWP, the first information field needs to be filled (that is, the number of bits of the resource indication information required by the target BWP is greater than the number of bits of the 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 filled with 0, thereby avoiding the situation where, when the network side device indicates invalid resource indication information, the terminal uses a filling method of filling 1, resulting in the invalid resource indication information becoming valid resource indication information, but the resource indication information cannot actually be used for scheduling, thereby resulting in inconsistent understanding of the actual scheduling information by the network side device and the terminal.

[0167] In other embodiments, when the resource allocation type of the target resource unit is type1, dynamic, type 2 and μ=0, the first information field is all 1s, indicating invalid resource indication information. In this case, when the first information field is interpreted according to the target BWP and needs to be filled (that is, the number of bits of the resource indication information required by the target BWP is greater than the number of bits of the 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 filled with 1, thereby avoiding the situation where, when the network side device indicates invalid resource indication information, the terminal uses a filling method of filling with 0, resulting in the invalid resource indication information becoming valid resource indication information, but the resource indication information cannot actually be used for scheduling, thereby resulting in inconsistent understanding of the actual scheduling information by the network side device and the terminal.

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

[0169] That is, in the embodiment of the present application, the filling value is related to the defined value of the invalid resource indication information.

[0170] For example, when the definition value of invalid resource indication information is all 0, fill it with 0; when the definition value of invalid resource indication information is all 1, fill it with 1. This can avoid filling in values ​​inconsistent with the invalid value, causing the invalid resource indication information to become valid resource indication information, and further causing the network side equipment and the terminal to have inconsistent understanding of the actual scheduling information.

[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 may not be adjusted, that is, when the first information field needs to be filled according to the target BWP, the first information field can be filled with 0.

[0172] Example 2-2:

[0173] In some embodiments of the present application, the terminal may further determine whether to perform fill processing on the first information field according to whether the first information field indicates invalid resource indication information.

[0174] 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 the bandwidth of the target BWP is greater than the bandwidth of the first BWP, or the frequency domain resources (such as the number of RBs) of the target BWP are more 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, when the first information field indicates invalid resource indication information, it is determined not to perform filling processing on the first information field, and / or the target resource indication information is determined according to the first information field.

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

[0177] Exemplarily, when the resource allocation type of the target resource unit is type 0, 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 scheduling information based on the target resource indication information, it is determined that the target object is not scheduled.

[0178] Exemplarily, when the resource allocation type of the target resource unit is type 1, dynamic, or type 2 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 the resource indication information required by the target BWP is greater than the number of bits of the 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 (such as the number of RBs) of the target BWP are more than the frequency domain resources of the first BWP, the terminal may not fill the first information field, and / or directly use the invalid resource indication information 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 is not 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 converting invalid resource indication information into valid resource indication information, thereby avoiding the aforementioned problem A.

[0181] Exemplarily, when the resource allocation type of the target resource unit is type 0, 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 padded with 0s. Further optionally, the target resource indication information is determined based on the padded first information field.

[0182] Exemplarily, when the resource allocation type of the target resource unit is type 1, dynamic, or type 2 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 may 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, the embodiment of the present application may restrict the indication method of DCI to avoid the aforementioned problem A.

[0185] The following describes the DCI indication method in conjunction with Example 3.

[0186] Example 3:

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

[0188] In some embodiments, the first information field and / or the target resource indication information is obtained via a first DCI, the first DCI further comprising resource unit indication information, the resource unit indication information indicating the target resource unit. The first DCI does not support simultaneous indication of a target resource unit different from the first resource unit and invalid resource indication information; or, the first DCI is not expected to simultaneously indicate 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 indicate a BWP different from the current BWP to the first cell and simultaneously indicate invalid resource indication information to the first cell.

[0191] Optionally, the first DCI may support indicating a BWP different from the current BWP to the second cell, and at the same time indicate invalid resource indication information to the first cell.

[0192] Optionally, the target resource pair being different from the first resource unit may refer to:

[0193] 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, for example, the number of bits of the resource indication information required by the target resource unit is greater than the number of bits of the 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; or

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

[0196] Optionally, when the second condition is met, the DCI is not constrained as in Example 3.

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

[0198] Configured object set information;

[0199] Object combination information is configured;

[0200] Configure / activate / be configured to use the second indication scheme.

[0201] That is, when the second condition is satisfied, Example 3 is not used.

[0202] Optionally, when the second condition is not met, use this embodiment 3, or when the first condition is met, use this embodiment 3.

[0203] In some scenarios, the aforementioned problem A occurs in some specific circumstances. For example, when the terminal uses the first indication scheme, interprets the first information field according to the target resource unit, and adopts the filling method of filling 0, and the resource allocation type of the target resource unit is type 1, type 2, and the SCI is the second SCS, therefore, one design idea is to avoid the above problem A by constraining the terminal configuration / activation / use of the indication scheme.

[0204] It should be understood that the indication scheme in the embodiments of the present application can be configured per object, such as per scheduling cell, or it can be other configuration granularity, such as per resource unit, such as per BWP / per BWP combination / BWP indication information per code point configuration. In this way, in the event of resource unit switching, 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 where problems may occur, thereby solving problem A.

[0205] In the following, the selection of the indication scheme for terminal configuration / activation / use is described in conjunction with Example 4.

[0206] Example 4:

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

[0208] The terminal determines, based on the first information, an indication scheme to configure / activate / use, and / or determines an indication scheme not to configure / activate / use. For example, the terminal determines an indication scheme to configure / activate / use between the first indication scheme and the second indication scheme, and / or determines an indication scheme not to configure / activate / use.

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

[0210] a resource allocation type of at least one resource unit;

[0211] an 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 of the at least one resource unit, such as the number of RBs included, the number of carriers, etc.;

[0214] The number of bits of resource indication information required by 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 scheduled or indicated resource unit.

[0216] For example, the at least one resource unit is at least one BWP, and the at least one BWP 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 may be applicable to a specific object, such as a specific cell, a specific cell combination, or a specific cell set, or may be applicable to any object or all objects, such as all cells, all cell combinations, or all cell sets. Optionally, the specific object may be predefined or indicated by a network-side device.

[0218] Example 4-1:

[0219] In some embodiments, the terminal determines, based on the first information, an indication scheme to configure / activate / use, and / or determines an indication scheme not to configure / activate / use, including:

[0220] If the third condition is met, determine to configure / activate / use the second indication scheme, and / or determine not to configure / activate / use the first indication scheme; and / or

[0221] If the third condition is not met, it is determined to configure / activate / use the first indication scheme, and / or it is determined not to configure / activate / use the second indication scheme.

[0222] In this embodiment of the present application, if the third condition is met, it can be considered that when interpreting the first information field based on the target BWP, the first information field needs to be padded. If it is padded with zeros, the aforementioned problem A may occur, affecting the interpretation of the actual scheduling information. In this case, the second indication scheme can be configured / activated / used, that is, determining the scheduling information based on the object indication information. Optionally, in this case, the terminal can ignore the first information field, or ignore the padded first information field.

[0223] Exemplarily, 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 at least one of type 1, dynamic type and type 2 and the SCS is a 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 resource of the at least one resource unit is different from 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 different from the bandwidth or frequency domain resource of all other resource units;

[0228] 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, for example, 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 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 other resource units configured on the terminal except for the at least one resource unit. Optionally, the at least one resource unit and the other resource units are associated with the same object, for example, the same cell / cell combination / cell set.

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

[0232] When the resource allocation type of the at least one resource unit includes at least one of type 1, dynamic type, and type 2 and the SCS is a 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 one 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 at least one of type 1, dynamic type, and type 2 and the SCS is 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 at least one other resource unit, then:

[0235] 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 the at least one resource unit includes at least one of type 1, dynamic type, and type 2 and the SCS is 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] The terminal determines to configure / activate / use the first indication scheme, and / or determines 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 and type 2 and the SCS is any one 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, based on the first information, an indication scheme to configure / activate / use, and / or determines an indication scheme not to configure / activate / use, including:

[0239] If the fourth condition is met, determine to configure / activate / use the first indication scheme, and / or determine not to configure / activate / use the second indication scheme; and / or

[0240] In some embodiments, if the fourth condition is not met, it is determined to configure / activate / use the second indication scheme, and / or it is determined not to configure / activate / use the first indication scheme.

[0241] In an embodiment of the present application, when the fourth condition is met, it can be considered that when interpreting the first information field according to the target BWP, there is no need 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] Exemplarily, 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 at least one of type 0, dynamic type, and type 2 and the SCS of the target resource unit is a first SCS;

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

[0246] As a specific example, if the fourth condition includes that the resource allocation type of the 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, then:

[0247] When the resource allocation type of the 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 the first indication scheme, and / or determines not to configure / activate / use the 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 one of the first SCSs, 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 that the resource allocation type of the 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 SCSs, 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 at least one other resource unit, then:

[0250] The terminal determines to configure / activate / use the first indication scheme, and / or determines not to configure / activate / use the second indication scheme, when the resource allocation type of the 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 SCSs, 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; or

[0251] 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 one of the first SCSs, or 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 in certain specific circumstances. For example, the terminal uses the first indication scheme, interprets the first information field according to the target resource unit, adopts the filling method of filling with 0, and the first information field is all 1, indicating invalid resource indication information. Therefore, one design idea is to avoid the above problem A by constraining the resource unit configuration on the terminal side.

[0253] The resource unit configuration on the terminal side is described below in conjunction with Example 5.

[0254] Example 5:

[0255] In some embodiments, this embodiment 5 may be applicable to a specific object, such as a specific cell, a specific cell combination, or a specific cell set, or may be applicable to any object or all objects, such as all cells, all cell combinations, or all cell sets. Optionally, the specific object may be predefined or indicated by a 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, the resource allocation types of the multiple resource units are the same. In this case, it can be considered that the invalid resource indication information is determined in the same manner 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 invalid resource indication information is recognized in the same manner before and after the resource unit switching, 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 a dynamic type and type 0. In this case, it can be considered that the invalid resource indication information is recognized in the same manner before and after the resource unit switching, that is, all 0s are considered invalid;

[0261] The resource allocation type of the at least one resource unit includes a dynamic type, type 0, and type 2, and the SCS of the resource unit is at least one of the first SCSs. In this case, it can be considered that the invalid resource indication information is recognized in the same manner 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 a dynamic type and type 1. In this case, it can be considered that the invalid resource indication information is recognized in the same manner before and after the resource unit switching, that is, all 1s are considered invalid;

[0263] The resource allocation type of the at least one resource unit includes a dynamic type, type 1, or type 2, and the SCS of the resource unit is at least one of the second SCSs. In this case, it can be considered that the invalid resource indication information is recognized in the same manner 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 considered that the first information field does not need to be padded after the resource unit is switched, so problem A caused by padding with zeros does not occur.

[0265] 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 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 all other resource units. In this case, it can be considered that the first information field does not need to be padded after the resource unit is switched, and problem A caused by padding with zeros will not occur.

[0266] The bandwidth of the at least one resource unit is smaller than the bandwidth of at least one other resource unit (for example, the bandwidth of the at least one resource unit is smaller than the bandwidth of all other resource units), and the other resource unit is a resource unit that cannot be indicated by control signaling. In this case, it can be considered 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 larger than the bandwidth of the at least one resource unit, there is no need to fill the first information field according to the at least one other resource unit. Therefore, problem A caused by padding with zeros does 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 (for example, 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 unit is a resource unit that cannot be indicated by control signaling. In this case, it can be considered 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, there is no need to fill the first information field according to the at least one other resource unit. Therefore, 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 (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. In this case, it can be considered 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, there is no need to fill the first information field according to the at least one other resource unit. Therefore, 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, all resource units of the terminal are not configured with sleep or do not support sleep;

[0270] The terminal is not configured with or does not support an enhanced hybrid automatic repeat request response HARQ-ACK codebook, for example, all resource units of the terminal are not configured to be dormant or do not support the enhanced HARQ-ACK codebook;

[0271] The terminal is not configured with or does not support HARQ retransmission, for example, all resource units are not configured with 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 unit are less than the frequency domain resources of at least one other resource unit, for example, including but not limited to: the number of RBs of the at least one resource unit is less than the number of RBs of the at least one other resource unit. The frequency domain resources of the at least one resource unit are equal to the frequency domain resources of the at least one other resource unit, for example, including but not limited to: the number of RBs of the at least one resource unit is equal to the number of RBs of the at least one other resource unit.

[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 scheduled or indicated resource unit.

[0275] For example, the at least one resource unit is at least one BWP, and the at least one BWP 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, for example, associated with the first object, such as the first cell / first cell combination / first cell set.

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

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

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

[0280] All other resource units described in the embodiment of the present application may refer to: all other resource units except 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 the resource unit is more than the number of bits of resource indication information required by other resource units, since the terminal cannot switch to the resource unit, there is no need to consider problem A caused by filling 0.

[0282] Example 5-2:

[0283] In some embodiments, when the second indication scheme is configured / activated / used, 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, the resource allocation types of the multiple resource units are the same. In this case, it can be considered that the invalid resource indication information is determined in the same manner 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 invalid resource indication information is recognized in the same manner before and after the resource unit switching, 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 a dynamic type and type 0. In this case, it can be considered that the invalid resource indication information is recognized in the same manner before and after the resource unit switching, that is, all 0s are considered invalid;

[0287] The resource allocation type of the at least one resource unit includes a dynamic type, type 0, and type 2, and the SCS of the resource unit is at least one of the first SCSs. In this case, it can be considered that the invalid resource indication information is recognized in the same manner 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 a dynamic type and type 1. In this case, it can be considered that the invalid resource indication information is recognized in the same manner before and after the resource unit switching, that is, all 1s are considered invalid;

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

[0290] 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. In this case, it can be considered that the first information field does not need to be filled after the resource unit is switched, so problem A caused by filling with zeros does not occur;

[0291] 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 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 all other resource units). In this case, it can be considered that the first information field does not need to be padded after the resource unit is switched, so problem A caused by padding with zeros does not occur.

[0292] The bandwidth of the at least one resource unit is smaller than the bandwidth of at least one other resource unit (for example, the bandwidth of the at least one resource unit is smaller than the bandwidth of all other resource units), and the other resource unit is a resource unit that cannot be indicated by control signaling. In this case, it can be considered 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 larger than the bandwidth of the at least one resource unit, there is no need to fill the first information field according to the at least one other resource unit. Therefore, problem A caused by filling with 0 does not occur.

[0293] 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 (for example, 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 unit is a resource unit that cannot be indicated by control signaling. In this case, it can be considered 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, there is no need to fill the first information field according to the at least one other resource unit. Therefore, problem A caused by filling 0 does not occur;

[0294] 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. In this case, it can be considered 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, there is no need to fill the first information field according to the at least one other resource unit. Therefore, problem A caused by filling 0 will not occur;

[0295] The terminal is not configured with a sleep resource unit or does not support sleep, for example, all resource units of the terminal are not configured with sleep or do not support sleep;

[0296] The terminal is not configured with or does not support an enhanced hybrid automatic repeat request response HARQ-ACK codebook, for example, all resource units of the terminal are not configured to be dormant or do not support the enhanced HARQ-ACK codebook;

[0297] The terminal is not configured with or does not support HARQ retransmission, for example, all resource units are not configured with 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 Embodiment 5-1 and Embodiment 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 the at least one resource unit is type 0;

[0301] The resource allocation type 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 the at least one resource unit is a dynamic type.

[0305] In Embodiment 5-1 and Embodiment 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 the first indication scheme is configured / activated / used, 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, the resource allocation types of the multiple resource units are the same. In this case, it can be considered that the invalid resource indication information is recognized in the same manner 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 invalid resource indication information is recognized in the same manner before and after the resource unit switching, 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 a dynamic type and type 0. In this case, it can be considered that the invalid resource indication information is recognized in the same manner before and after the resource unit switching, that is, all 0s are considered invalid;

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

[0317] 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 considered that the first information field is not padded after the resource unit is switched, and problem A caused by padding 0 will not occur;

[0318] 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 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 all other resource units). In this case, it can be considered that the first information field does not need to be padded after the resource unit is switched, and problem A caused by padding 0 will not occur.

[0319] The bandwidth of the at least one resource unit is smaller than the bandwidth of at least one other resource unit (for example, the bandwidth of the at least one resource unit is smaller than the bandwidth of all other resource units), and the other resource unit is a resource unit that cannot be indicated by control signaling. In this case, it can be considered 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 larger than the bandwidth of the at least one resource unit, there is no need to fill the first information field according to the at least one other resource unit. Therefore, problem A caused by filling with 0 does not occur.

[0320] 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 (for example, 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 unit is a resource unit that cannot be indicated by control signaling. In this case, it can be considered 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, there is no need to fill the first information field according to the at least one other resource unit. Therefore, problem A caused by filling 0 does not occur;

[0321] The number of bits of resource indication information required by the at least one resource unit is smaller 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 smaller than the number of bits of resource indication information required by all other resource units), and the other resource unit is a resource unit that cannot be indicated by control signaling. In this case, it can be considered 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, there is no need to perform padding processing on the first information field according to the at least one other resource unit. Therefore, problem A caused by padding with 0 will not occur.

[0322] The terminal is not configured with a sleep resource unit or does not support sleep, for example, all resource units of the terminal are not configured with sleep or do not support sleep;

[0323] The terminal is not configured with or does not support an enhanced hybrid automatic repeat request response HARQ-ACK codebook, for example, all resource units of the terminal are not configured to be dormant or do not support the enhanced HARQ-ACK codebook;

[0324] The terminal is not configured with or does not support HARQ retransmission, for example, all resource units are not configured with 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 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 the at least one resource unit is a dynamic type.

[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 in certain specific circumstances. For example, the terminal uses the first indication scheme, interprets the first information field according to the target resource unit, adopts a filling method of filling with 0, and the first information field is all 1, indicating invalid resource indication information. Therefore, one design idea is to avoid the above problem A by constraining the resource unit switching method on the terminal side.

[0334] The following describes resource unit switching and sending on the terminal side in conjunction with Example 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 field based on the switched resource units.

[0337] In some embodiments, the target resource unit (i.e., the resource unit after switching) 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, that is, 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 not to switch to the specific resource unit when switching resource units, the aforementioned problem A can be avoided.

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

[0339] The specific resource unit is a resource unit with a specific identifier (for example, ID is 0);

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

[0341] The resource allocation type of 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 a 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 resource of the specific resource unit is different from the bandwidth or frequency domain resource of at least one other resource unit;

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

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

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

[0349] It should be understood that the above-mentioned embodiments 1 to 6 can be implemented separately 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, and at the same time combine the constraints of at least one embodiment from embodiments 3 to 6 to avoid the aforementioned problem A.

[0350] As an example, for example, the terminal determines the target resource indication information according to the target resource unit based on Example 1, and at the same time can constrain the terminal's resource unit configuration to meet the constraint conditions in Example 5, or constrain the terminal's resource unit switching method to meet the constraint conditions in Example 6, etc.

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

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

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

[0354] The first information field is interpreted according to the interpretation information of the first information field to obtain the target resource indication information.

[0355] In some embodiments, the interpretation information of the first information field is indicated by a network-side device, for example, 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 the invalid resource indication information;

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

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

[0360] a filling value used to fill the first information field;

[0361] The method for interpreting the first information field.

[0362] For example, the interpretation information may indicate that invalid resource indication information is represented by a specific value (e.g., 1100) when the first information field is padded. Thus, if the first information field is 11 and it is determined based on the target resource unit that 00 is padded, the padded first information field will be 1100, indicating 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), and different values ​​of the first indication information may 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 reverse is also possible. 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, whether the first information field indicates invalid resource indication information can be indicated based on whether the interpretation information of the first information field includes second 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 is also possible. In this case, whether the first information field indicates invalid resource indication information does not need to be determined based on the value of the first information field.

[0365] In some embodiments, the interpretation information of the first information field may include third indication information for indicating the filling value used to fill the first information field, for example, indicating filling 0 or filling 1. Optionally, the third indication information may be 1 bit. For example, the 1-bit value of 1 indicates filling 0, and the value of 0 indicates filling 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 filling 0, and 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 filling 1.

[0366] In some embodiments, the interpretation method of the first information field may include fourth indication information, which is 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, the 1-bit value of 1 indicates that the target resource indication information is obtained by filling the first information field with 0, and the 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, and 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 may be a newly added information field.

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

[0369] For example, the value of the NDI field is 1 or 0, respectively, indicating that the first information field indicates valid or invalid resource indication information. For another example, the value of the NDI field is 1 or 0, respectively, indicating that the first information field is filled with 1 or 0. For another example, the value of the NDI field is 1 or 0, respectively, indicating 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 another example, flipping or not flipping NDI respectively indicates that the first information field indicates valid or invalid resource indication information. For another example, flipping or not flipping NDI respectively indicates filling 1 or filling 0. For another example, flipping or not flipping NDI respectively indicates obtaining the target resource indication information by filling 1 into the first information field or obtaining the target resource indication information by filling 0 into the first information field, or vice versa.

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

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

[0373] In some embodiments, the second DCI and the first DCI (ie, 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 for obtaining the target resource indication information.

[0375] In some 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 further embodiments, the second DCI is a DCI that indicates or triggers resource unit switching of at least one object, and the resource indication information corresponding to the at least one object is invalid resource indication information.

[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, the first information field is first interpreted according to the first resource unit. When 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 based on the first information field after filling or truncating.

[0380] For another 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 in other words, the first information field is not filled or truncated according to the target resource unit). Alternatively, the first information field is filled or truncated according to the target resource unit, but the scheduling information is not determined based on the first information field after filling or truncating, or in other words, the first information field after filling or truncating is ignored.

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

[0382] Mode 1: When the target resource indication information is a specific value (for example, all 0s, all 1s, or other values), determining that the target resource indication information is invalid;

[0383] Mode 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 when all N bits of the target resource indication information are 0, it is determined that the target resource indication information is invalid;

[0384] Mode 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 when N bits of the target resource indication information are all 1, determining that the target resource indication information is invalid, wherein the N bits are obtained by padding 1;

[0385] Mode 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 when N bits of the target resource indication information are all 1, determining that the target resource indication information is invalid, wherein the N bits are obtained by padding 1;

[0386] Mode 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 when all N bits of the target resource indication information are 0, determining that the target resource indication information is invalid;

[0387] Mode 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 of the N bits of the target resource indication information are all 0, determining that the target resource indication information is invalid;

[0388] Mode 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, determining that the target resource indication information is invalid;

[0389] In some embodiments, when the target resource indication information is invalid, the terminal determines that the target object is not scheduled, and / or the value corresponding to the target resource indication information does not correspond to 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 above-mentioned method of determining whether the resource indication information is invalid may be combined with the above-mentioned method of filling in the first information field.

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

[0393] For Mode 6 and Mode 7, M of the N bits of the target resource indication information may be the M bits of the first information field, i.e., excluding padding bits. Therefore, Mode 6 and Mode 7 are equivalent to determining the target resource indication information based on the first resource unit. For example, for the resource allocation type in Mode 6, when the first information field is all 0s, it indicates that the target resource indication information is invalid. Alternatively, for the resource allocation type in Mode 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 low-order M bits of the N bits, and the high-order NM bits can be 0, or the M bits are the high-order M bits of the N bits, and the low-order NM bits can be 0.

[0395] In summary, the terminal may determine the target resource indication information according to the currently used / activated resource unit or the target resource unit, and further determine the scheduling information of the target object according to 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 is conducive to ensuring the correctness of the target resource indication information determined by the terminal and ensuring that the terminal and the 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, so that the terminal can use an appropriate filling method to fill the first information field, which is conducive to ensuring the correctness of the target resource indication information determined by the terminal and ensuring that the terminal and the network side equipment have a consistent understanding of the actual scheduling information.

[0398] In some implementations, the terminal may constrain the DCI indication method for resource units and resource indication information, that is, constrain the DCI to not support the simultaneous indication of 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 the network side device have a consistent understanding of the actual scheduling information.

[0399] In some implementations, constraints can be placed on the configuration / activation / use of indication schemes in some 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 the network side equipment have a consistent understanding of the actual scheduling information.

[0400] In some implementations, resource unit configuration on the terminal side may be constrained, thereby ensuring the correctness of target resource indication information determined by the terminal based on the target resource unit, and ensuring that the terminal and the network side device have consistent understanding of the actual scheduling information.

[0401] In some implementations, the resource unit switching method on the terminal side can be constrained to ensure the correctness of the target resource indication information determined by the terminal based on the target resource unit, and to ensure that the terminal and the network side equipment 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 the network side device have consistent understanding of the actual scheduling information.
