The information determination method includes: receiving a first DCI, where the first DCI can schedule multiple target objects, and determining characteristic information of at least part of the information indication fields in the first DCI, so that the terminal can determine the characteristic information of at least part of the information fields in the first DCI, realizing information determination. Since the received first DCI can schedule multiple target objects, that is, one DCI schedules multiple target objects, thus, for multiple target objects, the network-side device does not need to send a DCI once for each target object, and the terminal does not need to receive a DCI once for each target object. It is only necessary to receive the first DCI that can schedule multiple target objects, thereby reducing the transmission overhead of the DCI.

[0019] In an embodiment of the present application, a first DCI is received. The first DCI can schedule a plurality of target objects. Then, the terminal only needs to determine the characteristic information of at least a partial information indication field in the first DCI, so that the terminal can determine the characteristic information of at least a partial information field in the first DCI, realizing information determination.

As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0033] The information determination method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0034] As Figure 2 shown, the embodiments of the present application provide an information determination method, which is applied to a terminal and includes:

[0035] Step 201: Receive a first downlink control information DCI, and the first DCI schedules multiple target objects;

[0036] Step 202: Determine the characteristic information of at least part of the information indication fields in the first DCI.

[0037] DCI is the downlink control information sent by the network-side device to the terminal. In the NR system, multiple DCI formats are defined. Different formats of DCI can be used for different purposes respectively. For example, it can be used for scheduling data, resource preemption, notifying slot format, and uplink power control, etc. Among them, a slot is a time slot.

[0038] The first DCI includes one or more information indication fields, which can be understood as fields. Different information indication fields in the DCI are used to indicate different information and correspond to different functions. The FDRA (Frequency Domain Resource Assignment) field is an information indication field in the DCI. Taking the FDRA field as an example, it is used to indicate the scheduled frequency domain resources, and its function is frequency domain resource allocation.

[0039] In this embodiment, first, the terminal receives the first DCI sent by the network-side device, and the received first DCI can schedule multiple target objects. After receiving the first DCI, the characteristic information of some information indication fields in the first DCI can be determined, thus realizing information determination. As an example, the above-mentioned target objects can include at least one of a carrier, a cell, and a BWP (bandwidth part). The above-mentioned scheduling target object can be understood as the target data on the scheduling target object, where the target data can be multiple uplink data, or multiple downlink data, or a part of uplink data and a part of downlink data.

[0040] As an example, the above-mentioned characteristic information can be determined by the terminal according to the protocol, determined by the terminal according to preset rules, indicated by the network-side device, or carried in the configuration information obtained by the terminal. The configuration information includes at least one of the following: ServingCellConfig or PDSCH-Config or PUSCH-Config. It should be noted that the configuration information obtained by the terminal can be the configuration information sent by the network-side device, the configuration information stipulated by the protocol, or the configuration information determined by the terminal.

[0041] In the information determination method of this embodiment, the terminal receives the first DCI, and the first DCI can schedule multiple target objects. Then, the terminal only needs to determine the characteristic information of at least some information indication fields in the first DCI, so that the terminal can determine the characteristic information of at least some information fields in the first DCI and realize information determination. Since the received first DCI can schedule multiple target objects, that is, one DCI schedules multiple target objects. In this way, for multiple target objects, the network-side device does not need to send a DCI for each target object, and the terminal does not need to receive a DCI for each target object. The terminal only needs to receive the first DCI that can schedule multiple target objects, thereby reducing the transmission overhead of the DCI.

[0042] Optionally, as Figure 3 shown, after step 202 of determining the characteristic information of at least part of the information indication field in the first DCI, the following is further included:

[0043] Step 203: Determine the scheduling information of multiple target objects according to the characteristic information of at least part of the information indication field in the first DCI.

[0044] The scheduling information of the target object can be understood as the scheduling information used to schedule the target object. In this embodiment, according to the characteristic information of at least part of the information indication field, the scheduling information of the above multiple target objects is determined, which can improve the accuracy of the determined scheduling information.

[0045] It should be noted that the information indication field corresponding to multiple sub-indication fields can be understood as: under the same function, but the corresponding target objects may have different information fields, or it can be understood as multiple sub-information fields included in the information indication field. For example, if the information indication field is frequency domain resource allocation, and there are two frequency domain resource allocation fields in the DCI and they are for different scheduled cells, then the information indication field can be regarded as the whole of all frequency domain resource allocation fields in the DCI, and the two frequency domain resource allocation fields are two sub-indication fields respectively; or it can be understood as part of the information indication field, or it can be understood as part of the bits within the information indication field. For example, if the information indication field corresponds to 10 bits, the first 5 bits are one sub-indication field and the last 5 bits are another sub-indication field.

[0046] Optionally, the characteristic information of at least part of the information indication field includes at least one of the following:

[0047] The number of sub-indication fields corresponding to each information indication field in at least part of the information indication field;

[0048] The number of bits of each information indication field in at least part of the information indication field;

[0049] The number of bits of the sub-indication field corresponding to each information indication field in at least part of the information indication field;

[0050] The type of at least part of the information indication field.

[0051] Among them, the number of bits of the information indication field is the sum of the number of bits of the sub-indication fields corresponding to it. The type of at least part of the information indication field can be understood as the overall type of at least part of the information indication field, or it can be the type of each information indication field in at least part of the information indication field.

[0052] Optionally, determining the characteristic information of at least part of the information indication field in the first DCI includes at least one of the following:

[0053] Obtain feature indication information, where the feature indication information indicates the feature information of at least part of the information indication field;

[0054] Determine the type of at least part of the information indication field in the first DCI, and determine the sub-feature information of at least part of the information indication field according to the type of at least part of the information indication field;

[0055] Wherein, the sub-feature information includes at least one of the following:

[0056] The number of sub-indication fields corresponding to each information indication field in at least part of the information indication field;

[0057] The number of bits of each information indication field in at least part of the information indication field;

[0058] The number of bits of the sub-indication field corresponding to each information indication field in at least part of the information indication field.

[0059] That is, in this embodiment, the feature indication information indicating the feature information of at least part of the information indication field can be obtained, so as to determine the feature information of at least part of the information indication field in the first DCI. It is also possible to first determine the type of at least part of the information indication field, and then determine the sub-feature information of at least part of the information indication field through the type of at least part of the information indication field, so as to realize the determination of the feature information of at least part of the information indication field. The accuracy of the determined feature information of at least part of the information indication field can be improved.

[0060] As an example, the above feature indication information can be specified by the protocol, obtained by the terminal according to preset rules, or sent by the network-side device.

[0061] Optionally, determining the type of at least part of the information indication field in the first DCI includes:

[0062] Obtain type indication information, where the type indication information indicates the type of at least part of the information indication field.

[0063] The type indication information indicating the type of at least part of the information indication field can be obtained, so as to determine the type of at least part of the information indication field in the first DCI.

[0064] As an example, the above type indication information can be specified by the protocol, obtained by the terminal according to preset rules, or sent by the network-side device.

[0065] For example, the terminal may receive type indication information sent by a network-side device. The type indication information may be RRC (Radio Resource Control) signaling, MAC-CE (Media Access Control-Control Element) signaling, or DCI. The type of the information indication field is configured, enabled, disabled, or modified through the type indication information, so as to determine the type of the information indication field.

[0066] Optionally, obtain type indication information, where the type indication information indicates the type of at least part of the information indication fields, including: the type indication information indicates the type of each information indication field in at least part of the information indication fields.

[0067] The number of at least part of the information indication fields may be one or more. In this embodiment, obtain type indication information, where the type indication information can indicate the type of each information indication field in at least part of the information indication fields. That is to say, the type of each information indication field in at least part of the information indication fields can be determined, and the sub-feature information of at least part of the information indication fields can be determined according to the type of each information indication field in at least part of the information indication fields.

[0068] Optionally, at least part of the information indication fields in the first DCI include a first information indication field of a first type and / or a second information indication field of a second type.

[0069] For different type cases of at least part of the information fields in the first DCI, different schedulings can be determined. In this embodiment, the type of at least part of the information indication fields may include a first type and / or a second type. Subsequently, the scheduling of multiple target objects can be determined based on the first information indication field of the first type and / or the second information indication field of the second type in at least part of the information indication fields, thereby improving the accuracy of the scheduling of the multiple target objects determined.

[0070] Optionally, when the first DCI includes a first information indication field, the number of sub-indication fields corresponding to any information indication field in the first information indication field is N or M, M < N, and N is the number of multiple target objects.

[0071] M is a positive integer, and N is an integer greater than 1. In this embodiment, if there is a first information indication field of a first type in the first DCI, the number of sub-indication fields corresponding to any first information indication field is at most the number of multiple target objects, which can avoid the problem of resource waste caused by too many sub-indication fields.

[0072] Optionally, the first information indication field is a mandatory information indication field in the first DCI and / or the first information indication field has a default value.

[0073] It can be understood that the mandatory information indication field in the first DCI can be indicated as the first type, and the information indication field with a default value in the first DCI can also be indicated as the first type. As an example, the first type is a dedicated type. The dedicated type can be understood as being dedicated to a cell or BWP or carrier or data, that is, different cells or BWPs or carriers or data will have corresponding indications respectively.

[0074] Optionally, in at least some of the sub-indication fields corresponding to any information indication field in the first information indication field, each sub-indication field corresponds to a different scheduled target object. In this way, scheduling interference can be reduced and the stability of target object scheduling can be improved.

[0075] Optionally, when the DCI includes a second information indication field, the number of sub-indication fields corresponding to any information indication field in the second information indication field is N or 1, where N is the number of multiple target objects.

[0076] In this embodiment, if there is a second information indication field of the second type in the first DCI, the number of sub-indication fields corresponding to any second information indication field is the number of multiple target objects or 1, which can avoid the problem of resource waste caused by too many sub-indication fields.

[0077] Optionally, the second information indication field is an optional information indication field in the first DCI and / or the second information indication field does not have a default value.

[0078] It can be understood that the optional information indication field in the first DCI can be indicated as the second type, and the information indication field without a default value in the first DCI can also be indicated as the second type. As an example, the second type is a sharable type. The sharable type can be understood as being sharable among multiple cells or BWPs or carriers or data, that is, different cells or BWPs or carriers or data can correspond to the same indication.

[0079] As an example, the second information indication field may further include at least one of the following:

[0080] SRS resource indicator (SRI);

[0081] Beta offset;

[0082] TPC command (transmission power control command);

[0083] Fields related to PUCCH (physical uplink control channel).

[0084] For PUCCH-related fields, such as PUCCH resource indication information, and also such as HARQ (Hybrid Automatic Repeat reQuest) feedback latency, etc.

[0085] It can be understood that the information indication field of at least one of the above in the first DCI can be indicated as the second type.

[0086] Optionally, the characteristic information of at least part of the information indication field includes the number of sub-indication fields corresponding to each information indication field in at least part of the information indication field;

[0087] In the case where the first DCI includes the first information indication field of the first type, according to the determined characteristic information of at least part of the information indication field in the first DCI, determining the scheduling information of multiple target objects includes:

[0088] In the case where the first information indication field includes the first target information indication field, and at least part of the M sub-indication fields in the first target information indication field have corresponding first target objects, determining at least one of the following:

[0089] The first target object is scheduled according to the corresponding sub-indication field;

[0090] At least part of the other target objects do not support the function corresponding to the first target information indication field, where the first target information indication field is the information indication field with the number of corresponding sub-indication fields being M in the first information indication field.

[0091] The first target object is the target object corresponding to at least some of the M sub-indication fields in the first information indication field among multiple target objects. Since the number of sub-indication fields corresponding to the first information indication field of the first type can be M or N, if the first target information indication field is included in the first information indication field of the first type, that is, it means that the information indication field including the number of sub-indication fields is M in the first information indication field, it can be determined that the first target object is scheduled according to the corresponding sub-indication fields. It is also possible to include the first target information indication field in the first information indication field, and when at least some of the M sub-indication fields in the first target information indication field correspond to the first target object, it can be determined that at least some of the other target objects do not support the function corresponding to the first target information indication field. It can be understood that at least some of the other target objects do not support being scheduled by the sub-indication fields corresponding to the first target information indication field. For example, non-periodic CSI (Channel State Information) reports and / or non-periodic CSI requests and / or SRS (Sounding Reference Signals) and / or non-periodic SRS and / or non-periodic measurement reports. It should be noted that the other target objects are the objects other than the above-mentioned first target object among multiple target objects. In addition, each sub-indication field has a corresponding first target object, that is, at least some sub-indication fields have corresponding first target objects, which can be understood as each sub-indication field in at least some sub-indication fields has a corresponding first target object.

[0092] Optionally, the characteristic information of at least some information indication fields includes the number of sub-indication fields corresponding to each information indication field in at least some information indication fields;

[0093] When the first DCI includes the first information indication field of the first type, based on determining the characteristic information of at least some information indication fields in the first DCI, determining the scheduling information of multiple target objects includes:

[0094] When the first target information indication field is included in the first information indication field, and at least some of the M sub-indication fields in the first target information indication field have corresponding first target objects, determine at least one of the following:

[0095] The first target object is scheduled according to the corresponding sub-indication fields;

[0096] At least some of the other target objects support the function corresponding to the first target information indication field;

[0097] At least some of the other target objects are scheduled according to the first adjusted sub-indication fields;

[0098] Wherein, the first adjusted sub-indication field is the result of adjusting the sub-indication field corresponding to the first target object by using the first preset offset, and the first target information indication field is the information indication field in the first information indication field with the number of corresponding sub-indication fields being M.

[0099] That is, the first target object is the target object corresponding to at least some of the M sub-indication fields in the first information indication field among the multiple target objects. Since the number of sub-indication fields corresponding to the first information indication field of the first type can be M or N, if the first target information indication field is included in the first information indication field of the first type, it means that the information indication field with the number of sub-indication fields being M is included in the first information indication field. When the first target information indication field is included in the first information indication field and at least some of the M sub-indication fields of the first target information indication field have corresponding first target objects, it can be determined that the first target object is scheduled according to the corresponding sub-indication fields.

[0100] It is also possible to include the first target information indication field in the first information indication field, and when at least some of the M sub-indication fields of the first target information indication field correspond to the first target object, it is determined that at least some of the other target objects support the function corresponding to the first target information indication field. It can be understood that at least some of the other target objects support being scheduled by the sub-indication fields corresponding to the first target information indication field. It should be noted that the other target objects are the objects other than the above-mentioned first target object among the multiple target objects.

[0101] In addition, it is also possible to include the first target information indication field in the first information indication field, and when at least some of the M sub-indication fields of the first target information indication field correspond to the first target object, it is determined that at least some of the other target objects are scheduled according to the first adjusted sub-indication fields.

[0102] Optionally, the result of adjusting the sub-indication field corresponding to the first target object by using the first preset offset can be understood as offsetting the sub-indication field corresponding to the first target object by using the first preset offset to obtain the first adjusted sub-indication field. For example, if the sub-indication field corresponding to the first target object is 1 and it is offset by adding 1 (the first preset offset is 1), the obtained first adjusted sub-indication field is 2. It can also be understood as offsetting the meaning indicated by the sub-indication field corresponding to the first target object by using the first preset offset to realize the adjustment of the meaning indicated by the sub-indication field corresponding to the first target object, which can be considered as realizing the adjustment of the sub-indication field corresponding to the first target object, thereby obtaining the first adjusted sub-indication field. For example, if the sub-indication field corresponding to the first target object is 1 and the meaning indicated by the sub-indication field corresponding to the first target object is X, and it is offset by using the first preset offset, the meaning indicated by the obtained first adjusted sub-indication field is the result of offsetting X.

[0103] For example, the first DCI schedules cell CC1 and cell CC2. The MCS (Modulation and Coding) information indication field in the first DCI only carries a 5-bit MCS indication field and this MCS indication field corresponds to CC1. At this time, CC2 performs transmission using the value after offset delta1 relative to the MCS indication field of CC1, that is, the available MCS of CC2 = the MCS indication field of CC1 + delta1, or the MCS used by CC2 = the MCS indication field of CC1 - delta1. Optionally, the delta1 value of the MCS indication field of CC2 relative to the MCS indication field of CC1 can be configured through RRC, MAC-CE or DCI.

[0104] Optionally, the characteristic information of at least part of the information indication fields includes the number of sub-indication fields corresponding to each information indication field in at least part of the information indication fields;

[0105] When the first DCI includes a second information indication field of the second type, based on determining the characteristic information of at least part of the information indication fields in the first DCI, determining the scheduling information of multiple target objects includes:

[0106] When the second information indication field includes a second target information indication field and there is a corresponding second target object for the sub-indication field of the second target information indication field, determining at least one of the following:

[0107] The second target object is scheduled according to the corresponding sub-indication field;

[0108] At least part of the other target objects support the function corresponding to the second target information indication field;

[0109] At least part of the other target objects are scheduled according to at least part of the sub-indication fields corresponding to the second target object and at least part of the other target objects are scheduled according to the second adjusted sub-indication field;

[0110] Wherein, the second adjusted indication field is the result of adjusting the sub-indication field corresponding to the second target object using a second preset offset, and the second target information indication field is the information indication field with the number of corresponding sub-indication fields being 1 in the second information indication field.

[0111] The second target object is the target object corresponding to the sub-indication field of the second information indication field among multiple target objects. Since the number of sub-indication fields corresponding to the second information indication field of the second type can be 1 or N, if the second information indication field of the second type includes the second target information indication field, that is, it means that the second information indication field includes an information indication field with the number of sub-indication fields being 1, then it can be determined that the second target object is scheduled according to the corresponding sub-indication field.

[0112] It is also possible to include a second target information indication field in the second information indication field. When the sub-indication fields of the second target information indication field correspond to the second target object, it can be determined that at least some of the other target objects support the function corresponding to the second target information indication field. It can be understood that at least some of the other target objects are supported to be scheduled by the sub-indication fields corresponding to the second target information indication field. It should be noted that the other target objects here are the objects other than the above-mentioned second target object among the multiple target objects.

[0113] It is also possible to include a second target information indication field in the second information indication field. When the sub-indication fields of the second target information indication field correspond to the second target object, it can be determined that at least some of the other target objects are scheduled according to the sub-indication fields corresponding to at least some of the second target objects or it can be determined that at least some of the other target objects are scheduled according to the second adjusted sub-indication fields. It can be understood that at least some of the other target objects are supported to be scheduled by the sub-indication fields corresponding to at least some of the second target information indication field. It should be noted that the other target objects here are the objects other than the above-mentioned second target object among the multiple target objects.

[0114] For example, there is only one indication field in the frequency domain resource allocation field of the first DCI, and this indication field corresponds to CC11, and the indication field indicates to schedule RBs #1-10 on the BWP of cell CC1, then RBs #1-10 on the BWP of cell CC2 are also scheduled.

[0115] Optionally, the result of adjusting the sub-indication field corresponding to the second target object using the second preset offset can be understood as offsetting the sub-indication field corresponding to the second target object using the second preset offset to obtain the second adjusted sub-indication field. For example, if the sub-indication field corresponding to the second target object is 1 and it is offset by adding one (the second preset offset is 1), the obtained second adjusted sub-indication field is 2. It can also be understood as offsetting the meaning indicated by the sub-indication field corresponding to the second target object using the second preset offset to achieve the adjustment of the meaning indicated by the sub-indication field corresponding to the second target object, which can be considered as achieving the adjustment of the sub-indication field corresponding to the second target object, thereby obtaining the second adjusted sub-indication field. For example, if the sub-indication field corresponding to the second target object is 1 and using the second preset offset, the meaning indicated by the sub-indication field corresponding to the second target object is Y, and after offsetting it, the meaning indicated by the obtained second adjusted sub-indication field is the result of offsetting Y.

[0116] For example, the first DCI schedules cell CC1 and cell CC2. There is only one 5-bit sub-indication field in a certain information indication field of the first DCI and it corresponds to CC1. At this time, CC2 performs transmission using the value of delta2 after offset from the MCS indication field of CC1, that is, the MCS used by CC2 = the MCS indication field of CC1 + delta2, or the MCS used by CC2 = the MCS indication field of CC1 - delta2. Optionally, the delta2 value of this sub-indication field of CC2 relative to this sub-indication field of CC1 can be configured through RRC, MAC-CE or DCI.

[0117] Optionally, determining the characteristic information of at least part of the information indication field includes:

[0118] Determining the characteristic information of at least part of the information indication field according to the first configuration information of the scheduled cell.

[0119] That is, after receiving the first DCI, the characteristic information of at least part of the information indication field can be determined respectively according to the first configuration information of the scheduled cell corresponding to the first DCI.

[0120] Optionally, determining the characteristic information of at least part of the information indication field includes: determining the number and / or number of bits of the first target sub-indication field in the sub-indication field corresponding to at least part of the information indication field according to the first configuration information of the scheduled cell, where the first target sub-indication field is the sub-indication field corresponding to the scheduled cell.

[0121] After receiving the first DCI, the number and / or number of bits of the first target sub-indication field in the sub-indication field corresponding to at least part of the information indication field can be determined respectively according to the first configuration information of the scheduled cell corresponding to the first DCI. As an example, the number and / or number of bits of the first target sub-indication field in the sub-indication field corresponding to at least part of the information indication field can be determined according to the first configuration information of the scheduled cell corresponding to at least part of the information indication field. As an example, the first configuration information of the scheduled cell includes the second configuration information of each scheduled cell. Among them, the first configuration information may include ServingCellConfig or BWP-DownlinkDedicated, and the second configuration information may include PDSCH-Config and / or PUSCH-Config.

[0122] For example, ServingCellConfig or BWP-DownlinkDedicated in the scheduled cell contains the PDSCH-Config of each scheduled cell. According to these PDSCH-Configs, the number of bits and / or the number of the sub-indication field corresponding to each scheduled cell in the sub-indication field corresponding to at least part of the information indication field in the first DCI can be determined respectively.

[0123] For another example, ServingCellConfig or BWP-DownlinkDedicated in the scheduling cell contains PUSCH-Config of each scheduled cell. According to these PDSCH-Configs, the number of bits and / or the number of sub-indication fields corresponding to at least part of the information indication field and the sub-indication field corresponding to each scheduled cell can be determined respectively.

[0124] For another example, assume that the first DCI on CC1 schedules CC1 and CC2. Then, the BWP-DownlinkDedicated of CC1 contains the PDSCH-Configs of CC1 and CC2, which are PDSCH-Config-CC1 and PDSCH-Config-CC2 respectively. Among them, BWP-DownlinkDedicated is as follows:

[0125] "--ASN1START

[0126] --TAG-BWP-DOWNLINKDEDICATED-START

[0127] BWP-DownlinkDedicated ::= SEQUENCE {

[0128] ......omitted......

[0129] pdsch-Config-CC1 SetupRelease {PDSCH-Config} OPTIONAL, --Need M

[0130] pdsch-Config-CC2 SetupRelease {PDSCH-Config} OPTIONAL, --Need M

[0131] ......omitted......

[0132] }

[0133] --TAG-BWP-DOWNLINKDEDICATED-STOP

[0134] --ASN1STOP"

[0135] Thus, according to PDSCHConfig-CC1 in BWP-DownlinkDedicated, the number of bits and / or the number of sub-indication fields corresponding to CC1 in the sub-indication fields corresponding to at least part of the information indication fields in the first DCI can be determined. According to PDSCHConfig-CC2 in BWP-DownlinkDedicated, the number of bits and / or the number of sub-indication fields corresponding to CC2 in the sub-indication fields corresponding to at least part of the information indication fields in the first DCI can be determined.

[0136] Optionally, determining the characteristic information of at least part of the information indication fields includes:

[0137] Respectively according to the second configuration information of each scheduled cell, determine the number of bits and / or the number of the first target sub-indication fields in the sub-indication fields corresponding to at least part of the information indication fields, where the first target sub-indication field is the sub-indication field corresponding to the scheduled cell.

[0138] For at least part of the information indication fields, according to the second configuration information of the scheduled cell corresponding to at least part of the information indication fields, determine the scheduling of multiple target objects. As an example, the second configuration information may include PDSCH-Config and / or PUSCH-Config.

[0139] For example, respectively according to ServingCell-Config of each scheduled cell or PDSCH-Config in BWP-DownlinkDedicated, determine the number of bits and / or the number of sub-indication fields corresponding to each scheduled cell in the sub-indication fields corresponding to at least part of the information indication fields in the first DCI.

[0140] For example, respectively according to ServingCell-Config of each scheduled cell or PUSCH-Config in BWP-DownlinkDedicated, determine the number of bits and / or the number of sub-indication fields corresponding to each scheduled cell in the sub-indication fields corresponding to at least part of the information indication fields.

[0141] Optionally, when the third target information indication field in the first DCI corresponds to one sub-indication field, the first DCI schedules one target object; where the third target information indication field is an information indication field of a preset first type.

[0142] That is, when there is only one sub-indication field corresponding to the information indication field of the preset first type in the first DCI (assuming it corresponds to CC1), the first DCI can only schedule one target object.

[0143] As an example, the information indication field of the first type, i.e., the first information indication field, is preset that the information indication field of the first type can be a certain information indication field, some specific information indication fields, a preset number of information indication fields, or all information indication fields in the information indication field of the first type.

[0144] Optionally, when the first DCI schedules a target object, if the first DCI includes a second information indication field, and the second information indication field includes a fourth target information indication field corresponding to a plurality of sub-indication fields, then the second target sub-indication field among the plurality of sub-indication fields corresponding to the fourth target information indication field is valid.

[0145] If the first DCI includes a fourth target information indication field corresponding to a plurality of sub-indication fields and the fourth target information indication field is of the second type, then for the plurality of sub-indication fields of the fourth target information indication field, only a certain sub-indication field (the second target sub-indication field) is valid. As an example, the second target sub-indication field corresponds to a target object scheduled by the first DCI.

[0146] Optionally, when a fifth target information indication field in the first DCI corresponds to a sub-indication field, the first DCI schedules a target object; wherein, the fifth target information indication field is a preset information indication field of the second type.

[0147] That is, when there is only one sub-indication field corresponding to the preset information indication field of the second type in the first DCI (assuming corresponding to CC1), the first DCI can only schedule one target object.

[0148] As an example, the information indication field of the second type, i.e., the second information indication field, is preset that the information indication field of the second type can be a certain information indication field, some specific information indication fields, a preset number of information indication fields, or all information indication fields in the information indication field of the second type.

[0149] Optionally, when the first DCI schedules a target object, if the first DCI includes a first information indication field, and the first information indication field includes a sixth target information indication field corresponding to a plurality of sub-indication fields, then the third target sub-indication field among the plurality of sub-indication fields corresponding to the sixth target information indication field is valid.

[0150] If the first DCI includes a sixth target information indication field corresponding to a plurality of sub-indication fields and the sixth target information indication field is of the first type, then for the plurality of sub-indication fields of the sixth target information indication field, only a certain sub-indication field (the third target sub-indication field) is valid. As an example, the third target sub-indication field corresponds to a target object scheduled by the first DCI.

[0151] Optionally, when at least part of the information indication field in the first DCI indicates that a preset information indication field corresponds to a sub-indication field, the first DCI schedules a target object.

[0152] That is, as long as there is only one sub-indication field corresponding to the preset information indication field in at least part of the information indication field, it can be determined that the first DCI can only schedule one target object.

[0153] As an example, the preset information indication field may be a certain information indication field, some specific information indication fields, a preset number of information indication fields, or all information indication fields in the information indication field of the first DCI. That is, the type of information indication field in the preset information indication field may be the first type and / or the second type.
