[0176] In some embodiments, the value of the at least one information field is a first value, and the terminal determines that the cell is not scheduled.

[0177] In some embodiments, the value of the at least one information field is a second value, and the terminal determines that the downlink control information carries the secondary cell sleep indication information, or is one of type 3 hybrid automatic repeat acknowledgement and downlink control information carrying the secondary cell sleep indication information.

[0186] In some embodiments, the number of cells corresponding to the invalid FDRA information field does not satisfy a first relationship with a number threshold, and the terminal determines that the scenario includes unscheduled cells.

[0187] In some embodiments, the information used to determine the actual scheduling cell of the downlink control information does not include the FDRA information field, and the terminal determines that the downlink control information carries secondary cell sleep indication information, or is one of type 3 hybrid automatic repeat confirmation and downlink control information carrying secondary cell sleep indication information.

[0190] In some embodiments, under the condition that the downlink control information includes an invalid FDRA information field value and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or the value is 0, the terminal determines, based on the first information, that the scenario corresponding to the condition is that the downlink control information carries cell sleep indication information or the cell is not scheduled.

[0191] In some embodiments, the scenario is one of type 3 hybrid automatic repeat request confirmation and downlink control information carrying secondary cell sleep indication information, and the terminal determines type 3 hybrid automatic repeat request confirmation indication information field in the downlink control information.

[0192] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 and S202. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.

[0193] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

[0194] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0195] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0196] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2 .

[0197] In some embodiments, the network device may send downlink control information (eg, MC-DCI, Multi cell scheduling Downlink Control Information) for scheduling multiple cells to the terminal.

[0198] Compared to traditional downlink control information (legacy DCI), one MC-DCI can be used to schedule multiple cells (or one of multiple cells), while one legacy DCI can only be used to schedule one cell.

[0199] For example, in some embodiments, the format of MC-DCI and the format of legacy DCI may be different. For example, the format of MC-DCI includes but is not limited to DCI 0_3 and DCI 1_3, and the format of legacy DCI includes but is not limited to DCI 0_0, DCI 0_1, DCI 1_0, DCI 1_1, DCI 2_0, and DCI 2_1.

[0200] The downlink control information may include at least one information field (also referred to as a field), such as a frequency domain resource allocation (FDRA, Frequency Domain Resource Assignment) information field.

[0201] In some embodiments, the value of the FDRA information field may be invalid. When the value of the FDRA information field is invalid, the frequency domain resources determined based on the FDRA information field are invalid frequency domain resources. For example, the frequency domain resources are before the frequency domain range corresponding to the current BWP (BandWidth Part). Exemplarily, the invalid FDRA value includes at least one of the following:

[0202] When the resource allocation type is type 0 (Type 0), the value of all bits in the FDRA information field is 0 (all 0 for type 0);

[0203] When the resource allocation type is Type 1 (Type 1), all bits in the FDRA information field are set to 1 (all 1 for type 1).

[0204] When the resource allocation type is dynamic, if the corresponding resource allocation type is type 0 (Type0), the value of all bits in the FDRA information field is 0; if the corresponding resource allocation type is type 1 (Type1), the value of all bits in the FDRA information field is 1.

[0205] In the case of Type 2 resource allocation, if the corresponding SCS (Sub-Carrier Spacing) parameter μ = 1, all bits in the FDRA information field are 0. If the corresponding SCS parameter μ = 0, all bits in the FDRA information field are 1. For example, μ = 0 corresponds to an SCS of 15 kHz, and μ = 1 corresponds to an SCS of 30 kHz.

[0206] For legacy DCI, taking DCI 1_1 as an example, if the value of the FDRA information field corresponding to DCI 1_1 is invalid, and the one shot HARQ (Hybrid Automatic Repeat reQuest) ACK) information field does not exist or the value is 0, the scenario corresponding to this condition can be that the DCI carries secondary cell dormancy (Scell ​​dormancy) indication information, and multiple information fields in the DCI can be re-cultivated to indicate the dormancy state of the secondary cell.

[0207] When MC-DCI is introduced, the type of the FDRA information field may be Type-2 (of course, the name of the type is not limited thereto and may also be named by other names). For the Type-2 information field, MC-DCI includes at least one information field of this type, and a single information field of the at least one information field of this type is used to indicate relevant information of a single scheduled cell.

[0208] For example, for the FDRA information field, MC-DCI can include multiple FDRA information fields, with a single FDRA information field used to indicate resource allocation information for a single cell. For example, MC-DCI includes four FDRA information fields, and MC-DCI is used to schedule four cells: Cell#1, Cell#2, Cell#3, and Cell#4. The first FDRA information field can be used to indicate resource allocation information for Cell#1, the second FDRA information field can be used to indicate resource allocation information for Cell#2, the third FDRA information field can be used to indicate resource allocation information for Cell#3, and the fourth FDRA information field can be used to indicate resource allocation information for Cell#4.

[0209] Under the condition that the MC-DCI contains an invalid FDRA information field value (for example, the value of part of the FDRA information field is invalid, or the value of all the FDRA information fields is invalid), and the one shot HARQ-ACK information field does not exist or the value is 0, the corresponding scenario can not only carry the secondary cell sleep indication information for MC-DCI, but also correspond to another scenario: the cell is not scheduled. For example, the value of the second FDRA information field in the above four FDRA information fields is invalid, and the one shot HARQ-ACK information field does not exist or the value is 0. The scenario corresponding to this condition may be that Cell#2 is not scheduled, or that MC-DCI carries the secondary cell sleep indication information. When the condition only includes that the MC-DCI contains an invalid FDRA information field value, the scenarios corresponding to this condition may include the following three: MC-DCI carries the secondary cell sleep indication information, and the cell does not schedule type 3 hybrid automatic repeat acknowledgement (Type-3 HRAQ-ACK).

[0210] In some embodiments, under the condition that the value of the FDRA information field is invalid, in addition to corresponding to the above two scenarios, other scenarios can also be corresponded, such as type 3 hybrid automatic repeat confirmation, in which case the value of one shot HARQ-ACK is 1; for example, type 1 and / or type 2 codebook retransmission (e.g., Type 1 & type 2 codebook retransmission), in which case the value of the HRAQ-ACK retransmission indication information field is 1.

[0211] It can be seen that after the introduction of MC-DCI, when the MC-DCI contains an invalid FDRA information field value, there are relatively more corresponding scenarios, which will lead to the technical problem of the terminal malfunctioning due to the inability to distinguish the scenarios.

[0212] It should be noted that for type 1 and / or type 2 codebook retransmission scenarios, the HRAQ-ACK retransmission indication information field can clearly distinguish the scenario from other scenarios. Therefore, the embodiments of the present disclosure mainly describe how to distinguish the three scenarios of MC-DCI carrying secondary cell sleep indication information, cell unscheduled, and type 3 hybrid automatic retransmission confirmation.

[0213] In a first aspect, embodiments of the present disclosure provide a method for receiving information. Figure 3 is a schematic flow chart illustrating a method for receiving information according to an embodiment of the present disclosure. The method for receiving information illustrated in this embodiment can be executed by a terminal.

[0214] As shown in FIG3 , the information receiving method may include the following steps:

[0215] In step S301, downlink control information (e.g., MC-DCI) sent by a network device is received, where the downlink control information is used to schedule multiple cells;

[0216] In step S302, a scenario is determined according to first information, wherein the downlink control information includes an invalid frequency domain resource allocation FDRA information field value.

[0217] It should be noted that the embodiment shown in FIG. 3 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0218] In some embodiments, the scenario includes at least one of the following: type 3 hybrid automatic repeat request acknowledgement HARQ-ACK; downlink control information carries secondary cell sleep indication information; and the cell is not scheduled.

[0219] In some embodiments, after receiving downlink control information, the terminal can determine whether the downlink control information contains an invalid FDRA information field value. When it is determined that the value of an FDRA information field in the downlink control information is invalid, or when it is determined that the values ​​of multiple FDRA information fields in the downlink control information are invalid, it can be determined that the downlink control information contains an invalid FDRA information field value.

[0220] According to an embodiment of the present disclosure, under the condition that the downlink control information includes an invalid FDRA information field value, the terminal can determine the scenario corresponding to the condition based on the first information, so that the terminal can accurately distinguish the scenario corresponding to the condition, and then perform subsequent operations based on the distinguished scenario, which is conducive to avoiding the technical problem of the terminal being unable to distinguish the scenario corresponding to the condition and erroneous operation.

[0221] The specific situation of the first information and how to distinguish scenarios based on the first information will be explained in subsequent embodiments and will not be described in detail here.

[0222] In some embodiments, the first information includes at least one of the following:

[0223] The type of at least one other information field other than the FDRA information field in the information field corresponding to the reference cell in the downlink control information;

[0224] a value of at least one first information field repurposed in the information field corresponding to the reference cell in the downlink control information;

[0225] at least one bit in at least one first information field of the corresponding reference cell in the downlink control information;

[0226] A newly defined information field corresponding to the reference cell in the downlink control information;

[0227] The FDRA information field corresponding to the reference cell in the downlink control information;

[0228] The number of cells corresponding to invalid FDRA information field values;

[0229] Information used to determine the cell where downlink control information is actually scheduled.

[0230] In some embodiments, the first information field includes at least one of the following:

[0231] Modulation and Coding Scheme (MCS) information field;

[0232] New Data Indicator (NDI) information field;

[0233] Redundancy Version (RV) information field;

[0234] Hybrid automatic repeat request process number (HARQ process number) information field;

[0235] Antenna port information field.

[0236] Demodulation Reference Signal sequence initialization (DMRS (Demodulation Reference Signal) sequence initialization) information field.

[0237] In some embodiments, the MCS information field, the NDI information field, and the RV information field may be information fields of a transport block (TB) 1 or information fields of a TB2.

[0238] In some embodiments, the type of the MCS information field, the NDI information field, the RV information field, and the HARQ process number information field may be Type-2.

[0239] In some embodiments, the type of the DMRS sequence initialization information field may be type-1A (of course, the name of the type is not limited thereto and may also be named by other names). For the type-1A information field, the downlink control information includes one information field of this type, and this one information field is used to schedule all cells scheduled for the downlink control information.

[0240] In some embodiments, the type of the Antenna port information field may be Type-1A or Type-2.

[0241] In some embodiments, the at least one first information field to be refarmed may include an MCS information field, an NDI information field, an RV information field, a HARQ process number information field, an Antenna port information field, and a DMRS sequence initialization information field.

[0242] In some embodiments, the at least one first information field to be refarmed may include an MCS information field, an NDI information field, an RV information field, a HARQ process number information field, and an Antenna port information field.

[0243] In some embodiments, the at least one first information field to be refarmed may include an MCS information field, an NDI information field, an RV information field, and a HARQ process number information field.

[0244] In some embodiments, at least one first information field of refarming may include an MCS information field, an NDI information field, an RV information field, and a HARQ process number information field, wherein, when the type of the antenna port information field is Type-2, the first information field may also include the antenna port information field, and when the type of the antenna port information field is type-1A, the first information field does not include the antenna port information field.

[0245] It should be noted that the re-farming described in the embodiment of the present disclosure refers to the re-farming of an information domain, in which the information domain is not used to implement the original indication function, but is used to implement a new indication function after the re-farming.

[0246] For example, the MCS information field is originally used to indicate the modulation and coding strategy, but after refarming, it is used to indicate the sleep state of the secondary cell. For example, if the proportion of the at least one refarmed first information field is n bits, then the sleep state of n secondary cells can be indicated, wherein there can be a correspondence between the n bits and the n secondary cells, and the i-th bit of the n bits is used to indicate the sleep state of the i-th secondary cell among the n secondary cells. For example, if the i-th bit is 0, it is used to indicate that the secondary cell is in the sleep state, and if the i-th bit is 1, it is used to indicate that the secondary cell is not in the sleep state, wherein i and n are positive integers, and i is less than or equal to n.

[0247] In some embodiments, the information receiving method further includes: when it is determined that the downlink control information carries secondary cell sleep indication information, determining the sleep state of the secondary cell according to at least one first information field corresponding to the refarming of the reference cell in the downlink control information.

[0248] Based on the above embodiments, when the downlink control information includes an invalid frequency domain resource allocation (FDRA) information field value, there are three corresponding scenarios: Type 3 hybrid automatic repeat request confirmation (HARQ-ACK), downlink control information carrying secondary cell sleep indication information, and unscheduled cell. For different scenarios, the subsequent operations performed by the terminal may vary, which may lead to the above-mentioned technical problem of erroneous operation.

[0249] For example, the two scenarios of downlink control information carrying secondary cell sleep indication information and cell unscheduled are taken as examples. In the scenario of cell unscheduled, the operation performed by the terminal may include not communicating in the unscheduled cell; in the scenario of downlink control information carrying secondary cell sleep indication information, the operation performed by the terminal may include determining the sleep state of the secondary cell based on at least one first information field of the refarmed corresponding reference cell in the downlink control information. For example, if the proportion of the at least one first information field of the refarmed is n bits, the terminal can determine the sleep state of n secondary cells based on these n bits, that is, determine whether each of the n secondary cells is in the sleep state.

[0250] In some embodiments, the reference cell includes at least one of the following:

[0251] Primary cell Pcell;

[0252] at least one cell among the cells actually scheduled by the downlink control information;

[0253] at least one cell in the cell set corresponding to the downlink control information;

[0254] At least one of the cells corresponding to the invalid FDRA information field value;

[0255] At least one cell used to calculate blind detection information among the cells actually scheduled by the downlink control information.

[0256] In some embodiments, the cell set corresponding to the downlink control information may be a cell set consisting of cells that can be scheduled by the downlink control information. In some embodiments, the blind detection information includes at least one of the following: blind decoding (BD) and control channel element (CCE).

[0257] In some embodiments, the reference cell may be one of the cells actually scheduled by the downlink control information, or multiple cells among the cells actually scheduled by the downlink control information. For example, when the reference cell is one of the cells actually scheduled by the downlink control information, the reference cell may be the cell with the smallest ID (which may be referred to as an index) among the cells actually scheduled by the downlink control information, or may be the cell with the largest ID among the cells actually scheduled by the downlink control information. Of course, the present invention is not limited thereto, and the reference cell may also be a cell corresponding to any ID among the cells actually scheduled by the downlink control information.

[0258] In some embodiments, the reference cell may be a cell in the cell set corresponding to the downlink control information, or multiple cells in the cell set. For example, when the reference cell is a cell in the cell set, the cell may be the cell with the smallest identifier in the cell set, or the cell with the largest identifier in the cell set. Of course, the present invention is not limited thereto, and the reference cell may also be a cell corresponding to any identifier in the cell set.

[0259] In some embodiments, the reference cell may be one of the cells corresponding to the invalid FDRA information field value, or multiple cells among the cells corresponding to the invalid FDRA information field value. For example, when the reference cell is one of the cells corresponding to the invalid FDRA information field value, the reference cell may be the cell with the smallest identifier among the cells corresponding to the invalid FDRA information field value; or, the reference cell may be the cell with the largest identifier among the cells corresponding to the invalid FDRA information field value.

[0260] For example, among the four FDRA information fields, the first FDRA information field is used to indicate resource allocation information for Cell#1, the second FDRA information field is used to indicate resource allocation information for Cell#2, the third FDRA information field is used to indicate resource allocation information for Cell#3, and the fourth FDRA information field is used to indicate resource allocation information for Cell#4. When the value of the first FDRA information field is invalid, and the value of the third FDRA information field is invalid, the cells corresponding to the invalid FDRA information field values ​​are Cell#1 and Cell#3. If the reference cell is the cell with the smallest identifier among the cells corresponding to the invalid FDRA information field values, then the reference cell is Cell#1. If the reference cell is the cell with the largest identifier among the cells corresponding to the invalid FDRA information field values, then the reference cell is Cell#3. Of course, this is not limited to this, and the reference cell can also be a cell corresponding to any identifier among the cells corresponding to the invalid FDRA information field values.

[0261] In some embodiments, determining the scenario based on the first information includes: determining the scenario corresponding to the condition based on the first information is that the downlink control information carries cell sleep indication information or the cell is not scheduled, wherein the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or the value is 0.

[0262] For example, the terminal can first parse the FDRA information field and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. When it is determined that there is an invalid FDRA information field value and the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, there are only two scenarios corresponding to this condition: the downlink control information carries cell sleep indication information and the cell is not scheduled. The terminal can distinguish the scenario corresponding to the condition based on the first information, whether the downlink control information carries cell sleep indication information or the cell is not scheduled.

[0263] In some embodiments, the information receiving method also includes: the scenario is one of type 3 hybrid automatic repeat confirmation and downlink control information carrying secondary cell sleep indication information, and determining type 3 hybrid automatic repeat confirmation or downlink control information carrying secondary cell sleep indication information according to the single-transmitted hybrid automatic repeat request confirmation indication information field in the downlink control information.

[0264] For example, the terminal may first parse the FDRA information field in the downlink control information. When it is determined that there is an invalid FDRA information field value, there are three scenarios corresponding to this condition: type 3 hybrid automatic repeat confirmation, downlink control information carrying secondary cell sleep indication information, and cell unscheduled. Furthermore, the terminal may try to distinguish the scenarios based on the first information. When it is determined that the cell is unscheduled based on the first information, then there is no need to further distinguish, and the single-shot hybrid automatic repeat request confirmation indication information field may not be parsed; when the first scenario includes one of type 3 hybrid automatic repeat confirmation and downlink control information carrying secondary cell sleep indication information, then it is necessary to further distinguish the scenarios. The terminal may distinguish whether the scenario is type 3 hybrid automatic repeat confirmation or downlink control information carrying secondary cell sleep indication information based on the single-shot hybrid automatic repeat request confirmation indication information field in the downlink control information.

[0265] It can be seen that in some embodiments, the condition described in the embodiments of the present disclosure is only that the downlink control information includes an invalid FDRA information field value. In other embodiments, the condition described in the embodiments of the present disclosure may be that the downlink control information includes an invalid FDRA information field value, and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or the value is 0.

[0266] The following uses several embodiments to exemplify scenarios corresponding to determining conditions based on the first information.

[0267] In some embodiments, determining the scenario according to the first information includes at least one of the following:

[0268] The value of at least one information field is the first value, and it is determined that the cell is not scheduled;

[0269] The value of at least one information field is the second value, determining that the downlink control information carries the secondary cell sleep indication information, or is one of type 3 hybrid automatic repeat request confirmation and the downlink control information carries the secondary cell sleep indication information.

[0270] In some embodiments, when the first information is the value of at least one other information field other than the FDRA information field in the information field corresponding to the reference cell in the downlink control information, the value of the at least one information field can be determined based on all bits in the at least one first information field.

[0271] For example, when the downlink control information includes an invalid FDRA information field value, and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information and the cell being unscheduled. When the value of at least one information field is a first value, the terminal can distinguish the scenario as specifically that the cell is unscheduled; when the value of at least one information field is a second value, the terminal can distinguish the scenario as specifically that the downlink control information carries cell sleep indication information.

[0272] It should be noted that the first value and the second value can be two different values. The first value in different embodiments can be the same or different, and the second value in different embodiments can be the same or different. For example, the first value can be 0 and the second value can be 1. Of course, it is not limited to this.

[0273] For example, when the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information, the cell being unscheduled, and hybrid automatic repeat request confirmation of type 3. When the value of at least one information field is a first value, the terminal can distinguish that the scenario is specifically that the cell is unscheduled; when the value of at least one information field is a second value, the terminal can distinguish that the scenario is one of the hybrid automatic repeat request confirmation of type 3 and the downlink control information carrying secondary cell sleep indication information.

[0274] In this case, the terminal can further distinguish the scenarios according to the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, it can be determined that the downlink control information carries the secondary cell sleep indication information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field exists and the value is 1, type 3 hybrid automatic repeat confirmation can be determined.

[0275] In some embodiments, determining the scenario according to the first information includes at least one of the following:

[0276] The value of at least one bit in at least one first information field is a first value, determining that the cell is not scheduled;

[0277] The value of at least one bit in at least one first information field is the second value, determining that the downlink control information carries the secondary cell sleep indication information, or is one of type 3 hybrid automatic repeat request confirmation and downlink control information carrying the secondary cell sleep indication information.

[0278] For example, when the downlink control information includes an invalid FDRA information field value, and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information and the cell being unscheduled. When the value of at least one bit in at least one first information field is a first value, the terminal can distinguish that the scenario is specifically that the cell is unscheduled; when the value of at least one bit in at least one first information field is a second value, the terminal can distinguish that the scenario is specifically that the downlink control information carries cell sleep indication information.

[0279] For example, when the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of downlink control information carrying cell sleep indication information, cell unscheduled, and type 3 hybrid automatic repeat request confirmation. When the value of at least one bit in at least one first information field is a first value, the terminal can distinguish that the scenario is specifically that the cell is unscheduled; when the value of at least one bit in at least one first information field is a second value, the terminal can distinguish that the scenario is one of type 3 hybrid automatic repeat request confirmation and downlink control information carrying secondary cell sleep indication information.

[0280] In this case, the terminal can further distinguish the scenarios according to the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, it can be determined that the downlink control information carries the secondary cell sleep indication information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field exists and the value is 1, type 3 hybrid automatic repeat confirmation can be determined.

[0281] In some embodiments, the at least one bit in the at least one first information field corresponding to the reference cell in the downlink control information may be one bit or multiple bits in the proportion of the at least one first information field corresponding to the reference cell in the downlink control information. Specifically, when the at least one bit in the at least one first information field corresponding to the reference cell in the downlink control information is one bit in the proportion of the at least one first information field corresponding to the reference cell in the downlink control information, the bit may be any bit in the proportion of the at least one first information field corresponding to the reference cell in the downlink control information, for example, the first bit, or the last bit, and of course, may also be a bit between the first bit and the last bit.

[0282] For example, when this bit is the first bit in the proportion of at least one first information field in the corresponding reference cell in the downlink control information, the terminal can distinguish the scenarios by parsing the first bit in the proportion of the at least one first information field. Since, in the scenario where the downlink control information carries secondary cell sleep indication information, the at least one first information field in the reference cell is re-farmed to determine the sleep state of the secondary cell, the terminal needs to parse the bits after the first bit to determine the sleep state of the secondary cell. In the scenario where the cell is unscheduled, the terminal can determine that the reference cell is unscheduled, and therefore does not need to further parse the bits after the first bit, which helps save overhead.

[0283] For example, when this bit is the last bit in the proportion of at least one first information field in the corresponding reference cell in the downlink control information, the terminal can distinguish the scenarios by parsing the first bit in the proportion of the at least one first information field. In the case where the scenario is that the downlink control information carries secondary cell sleep indication information, refarming of at least one first information field in the reference cell is used to determine the sleep state of the secondary cell. In the case where refarming is used to determine the sleep state of the secondary cell, an association relationship may exist between the proportion of the at least one first information field in the reference cell and the secondary cell. The association relationship is generally associated with the secondary cell starting from the first bit of the proportion of the at least one first information field. In this case, the scenario is distinguished by the last bit in the proportion of the at least one first information field, and the association relationship between the bits before the last bit and the secondary cell does not need to be adjusted, which helps reduce the overhead of adjusting the mapping relationship.

[0284] In some embodiments, determining the scenario according to the first information includes at least one of the following:

[0285] The newly defined information field indicates a first value, determining that the cell is not scheduled;

[0286] The newly defined information field indicates a second value, and determines that the downlink control information carries the secondary cell sleep indication information, or is one of type 3 hybrid automatic repeat request confirmation and the downlink control information carries the secondary cell sleep indication information.

[0287] For example, when the downlink control information includes an invalid FDRA information field value and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information and the cell being unscheduled. When the newly defined information field indicates a first value, the terminal can distinguish that the scenario is specifically that the cell is unscheduled; when the newly defined information field indicates a second value, the terminal can distinguish that the scenario is specifically that the downlink control information carries cell sleep indication information.

[0288] It should be noted that the newly defined information field may occupy one or more bits. For example, in the case of occupying one bit, the first value may be 0 and the second value may be 1. Of course, it is not limited thereto.

[0289] For example, when the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information, the cell being unscheduled, and hybrid automatic repeat request confirmation of type 3. When the terminal indicates the first value in the newly defined information field, the terminal can distinguish that the scenario is specifically that the cell is unscheduled; when the terminal indicates the second value in the newly defined information field, the terminal can distinguish that the scenario is one of the hybrid automatic repeat request confirmation of type 3 and the downlink control information carrying secondary cell sleep indication information.

[0290] In this case, the terminal can further distinguish the scenarios according to the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, it can be determined that the downlink control information carries the secondary cell sleep indication information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field exists and the value is 1, type 3 hybrid automatic repeat confirmation can be determined.

[0291] In some embodiments, determining the scenario according to the first information includes at least one of the following:

[0292] The type of at least one other information field is the first type, and it is determined that the cell is not scheduled;

[0293] The type of at least one other information field is the second type, and it is determined that the downlink control information carries the secondary cell sleep indication information, or is one of type 3 hybrid automatic repeat request confirmation and the downlink control information carries the secondary cell sleep indication information.

[0294] For example, when the downlink control information includes an invalid FDRA information field value, and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information and the cell being unscheduled. When the type of at least one other information field is the first type, the terminal can distinguish that the scenario is specifically that the cell is unscheduled; when the type of at least one other information field is the second type, the terminal can distinguish that the scenario is specifically that the downlink control information carries cell sleep indication information.

[0295] It should be noted that the at least one other information field may include one information field, or include multiple information fields. For example, the information field included in the at least one other information field is not limited to the Antenna port information field, the HARQ process number information field, etc. The first type and the second type include but are not limited to type-1A, type-1B, type-1C, type-2, and type-3. Among them, for the type-1B information field, the downlink control information may include one information field of this type, and the type information may be used to indicate the index of the information combination of at least one scheduled cell; for the type-3 information field, the downlink control information may include one or more information fields of this type, and the type information may be determined as one of type-1A and type-2 by predefinition or network device configuration.

[0296] For example, when the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of downlink control information carrying cell sleep indication information, cell unscheduled, and hybrid automatic repeat request confirmation of type 3. When the type of at least one other information field is the first type, the terminal can distinguish the scenario as specifically cell unscheduled; when the type of at least one other information field is the second type, the terminal can distinguish the scenario as one of type 3 hybrid automatic repeat request confirmation and downlink control information carrying secondary cell sleep indication information.

[0297] In this case, the terminal can further distinguish the scenarios according to the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, it can be determined that the downlink control information carries the secondary cell sleep indication information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field exists and the value is 1, type 3 hybrid automatic repeat confirmation can be determined.

[0298] In some embodiments, determining a scenario according to the first information includes:

[0299] The value of the FDRA information field corresponding to the reference cell in the downlink control information is invalid, and it is determined that the downlink control information carries the secondary cell sleep indication information, or is one of type 3 hybrid automatic repeat acknowledgement and the downlink control information carries the secondary cell sleep indication information.

[0300] For example, under the condition that the downlink control information includes an invalid FDRA information field value, and the single-transmitted hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information and the cell being unscheduled. The terminal can distinguish the scenarios based on the value of the FDRA information field of the reference cell, wherein, when the value of the FDRA information field of the reference cell is invalid, the terminal can determine that the scenario is specifically the downlink control information carrying cell sleep indication information. It should be noted that the rule for distinguishing scenarios is pre-defined (for example, protocol agreement or network configuration), and the terminal determines that the scenario is specifically the downlink control information carrying cell sleep indication information when the single-transmitted hybrid automatic repeat request confirmation indication information field does not exist or has a value of 0, and the value of the FDRA information field of the reference cell is invalid, and will not distinguish the scenarios based on the value of the FDRA information field of other cells.

[0301] For example, when the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information, cell unscheduled, and type 3 hybrid automatic repeat confirmation. The terminal can distinguish the scenarios based on the value of the FDRA information field of the reference cell, wherein, when the value of the FDRA information field of the reference cell is invalid, the terminal can determine one of type 3 hybrid automatic repeat confirmation and downlink control information carrying secondary cell sleep indication information. It should be noted that the rule for distinguishing the scenarios is pre-defined (for example, protocol agreement or network configuration), and the terminal will determine one of type 3 hybrid automatic repeat confirmation and downlink control information carrying secondary cell sleep indication information only when the value of the FDRA information field of the reference cell is invalid, and will not distinguish the scenarios based on the value of the FDRA information field of other cells.

[0302] In this case, the terminal can further distinguish the scenarios according to the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, it can be determined that the downlink control information carries the secondary cell sleep indication information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field exists and the value is 1, type 3 hybrid automatic repeat confirmation can be determined.

[0303] In some embodiments, determining the scenario according to the first information includes at least one of the following:

[0304] The number of cells corresponding to the invalid FDRA information field value and the number threshold satisfy a first relationship, and it is determined that the downlink control information carries the secondary cell sleep indication information, or is one of type 3 hybrid automatic repeat acknowledgement and downlink control information carrying the secondary cell sleep indication information;

[0305] The number of cells corresponding to the invalid FDRA information field does not satisfy the first relationship with the number threshold, and it is determined that the cell is not scheduled.

[0306] For example, when the downlink control information includes an invalid FDRA information field value, and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information and the cell being unscheduled. The terminal can distinguish the scenarios based on the number of cells corresponding to the invalid FDRA information field value, wherein, when the number of cells corresponding to the invalid FDRA information field value and the quantity threshold do not satisfy the first relationship, the scenario can be distinguished as specifically the cell being unscheduled; when the number of cells corresponding to the invalid FDRA information field value and the quantity threshold satisfy the first relationship, the terminal can distinguish the scenario as specifically the downlink control information carrying cell sleep indication information.

[0307] It should be noted that the quantity threshold and / or the first relationship can be determined based on the protocol agreement or configured by the network device, wherein the quantity threshold can be a value greater than or equal to 1, for example, it can be 2, and the first relationship can be, for example, the quantity is greater than the quantity threshold, or it can be the quantity is less than the quantity threshold, and there is no restriction on this.

[0308] For example, when the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information, cell unscheduled, and type 3 hybrid automatic repeat confirmation. The terminal can distinguish the scenarios based on the number of cells corresponding to the invalid FDRA information field value, wherein, when the number of cells corresponding to the invalid FDRA information field value and the number threshold do not satisfy the first relationship, the scenario can be distinguished as specifically cell unscheduled; when the number of cells corresponding to the invalid FDRA information field value and the number threshold satisfy the first relationship, the terminal can distinguish the scenario as type 3 hybrid automatic repeat confirmation and downlink control information carrying secondary cell sleep indication information.

[0309] In this case, the terminal can further distinguish the scenarios according to the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, it can be determined that the downlink control information carries the secondary cell sleep indication information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field exists and the value is 1, type 3 hybrid automatic repeat confirmation can be determined.

[0310] In some embodiments, determining the scenario according to the first information includes at least one of the following:

[0311] The information used to determine the actual scheduling cell of the downlink control information does not include the FDRA information field, and determines that the downlink control information carries the secondary cell sleep indication information, or is one of type 3 hybrid automatic repeat acknowledgement and the downlink control information carries the secondary cell sleep indication information;

[0312] The information used to determine the actual scheduling cell of the downlink control information includes the FDRA information field, which determines that the cell is not scheduled.

[0313] In some embodiments, there are two ways to determine the actual scheduling cell of the downlink control information, one of which is to determine the actual scheduling cell of the downlink control information based on the FDRA information field; the other is to determine the actual scheduling cell of the downlink control information based on the information field in the scheduled cell combination list (ScheduledCellCombo-List) received by RRC signaling and the MC DCI. For example, for DCI 0_3, the scheduled cell combination list can be ScheduledCellCombo-ListDCI-0-3, and for DCI 1_3, the scheduled cell combination list can be ScheduledCellCombo-ListDCI-1-3, and then the cell combination is determined in the list as the actual scheduled cell based on the information field scheduled cell indicator in the downlink control information.

[0314] Among them, when the RRC signaling is configured with a scheduling cell combination list, the terminal can determine that the information used to determine the actual scheduling cell of the downlink control information does not include the FDRA information field. When the RRC signaling is not configured with a scheduling cell combination list, it can determine that the information used to determine the actual scheduling cell of the downlink control information includes the FDRA information field.

[0315] For example, when the downlink control information includes an invalid FDRA information field value, and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information and the cell being unscheduled. When the information used to determine the cell actually scheduled by the downlink control information includes the FDRA information field, the terminal can distinguish the scenario as specifically that the cell is unscheduled; when the information used to determine the cell actually scheduled by the downlink control information does not include the FDRA information field, the terminal can distinguish the scenario as specifically that the downlink control information carries cell sleep indication information.

[0316] For example, when the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information, the cell being unscheduled, and hybrid automatic repeat acknowledgement of type 3. When the information used to determine the actual scheduling cell of the downlink control information includes the FDRA information field, the terminal can distinguish the scenario as specifically the cell being unscheduled; when the information used to determine the actual scheduling cell of the downlink control information does not include the FDRA information field, the terminal can distinguish the scenario as one of the type 3 hybrid automatic repeat acknowledgement and the downlink control information carrying secondary cell sleep indication information.

[0317] In this case, the terminal can further distinguish the scenarios according to the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, it can be determined that the downlink control information carries the secondary cell sleep indication information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field exists and the value is 1, type 3 hybrid automatic repeat confirmation can be determined.

[0318] In a second aspect, embodiments of the present disclosure provide a method for sending information. Figure 4 is a schematic flow chart illustrating a method for sending information according to an embodiment of the present disclosure. The method for sending information illustrated in this embodiment can be executed by a network device.

[0319] As shown in FIG4 , the information sending method may include the following steps:

[0320] In step S401, downlink control information is sent to the terminal, where the downlink control information is used to schedule multiple cells, wherein the downlink control information includes an invalid frequency domain resource allocation FDRA information field value, and the downlink control information is used by the terminal to determine first information, and the first information indication is used for the terminal to determine a scenario.

[0321] It should be noted that the embodiment shown in FIG. 4 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0322] In some embodiments, the scenario includes at least one of the following: type 3 hybrid automatic repeat request acknowledgement HARQ-ACK; downlink control information carries secondary cell sleep indication information; and the cell is not scheduled.

[0323] In some embodiments, after receiving downlink control information, the terminal can determine whether the downlink control information contains an invalid FDRA information field value. When it is determined that the value of an FDRA information field in the downlink control information is invalid, or when it is determined that the values ​​of multiple FDRA information fields in the downlink control information are invalid, it can be determined that the downlink control information contains an invalid FDRA information field value.

[0324] According to an embodiment of the present disclosure, the network device can send downlink control information to the terminal to schedule multiple cells, and under the condition that the downlink control information includes an invalid FDRA information field value, the terminal can be instructed through the first information to determine the scenario corresponding to the condition, so that the terminal can accurately distinguish the scenario corresponding to the condition, and then perform subsequent operations based on the distinguished scenario, which is conducive to avoiding the technical problem of the terminal being unable to distinguish the scenario corresponding to the condition and misoperating.

[0325] In some embodiments, the first information includes at least one of the following:

[0326] The type of at least one other information field other than the FDRA information field in the information field corresponding to the reference cell in the downlink control information;

[0327] a value of at least one first information field refarmed in the information field corresponding to the reference cell in the downlink control information;

[0328] at least one bit in at least one first information field of the corresponding reference cell in the downlink control information;

[0329] A newly defined information field corresponding to the reference cell in the downlink control information;

[0330] The FDRA information field corresponding to the reference cell in the downlink control information;

[0331] The number of cells corresponding to invalid FDRA information field values;

[0332] Information used to determine the cell where downlink control information is actually scheduled.

[0333] In some embodiments, the first information field includes at least one of the following:

[0334] Modulation and Coding Strategy (MCS) information field;

[0335] New Data Indicator (NDI) information field;

[0336] Redundancy version (RV) information field;

[0337] Hybrid automatic repeat request process number (HARQ process number) information field;

[0338] Antenna port information field.

[0339] Demodulation reference signal sequence initialization (DMRS sequence initialization) information field.

[0340] In some embodiments, the MCS information field, the NDI information field, and the RV information field may be the information field of TB1 or the information field of TB2.

[0341] In some embodiments, the type of the MCS information field, the NDI information field, the RV information field, and the HARQ process number information field may be Type-2.

[0342] In some embodiments, the type of the DMRS sequence initialization information field may be type-1A (of course, the name of the type is not limited thereto and may also be named by other names). For the type-1A information field, the downlink control information includes one information field of this type, and this one information field is used to schedule all cells scheduled for the downlink control information.

[0343] In some embodiments, the type of the Antenna port information field may be Type-1A or Type-2.

[0344] In some embodiments, the at least one first information field to be refarmed may include an MCS information field, an NDI information field, an RV information field, a HARQ process number information field, an Antenna port information field, and a DMRS sequence initialization information field.

[0345] In some embodiments, the at least one first information field to be refarmed may include an MCS information field, an NDI information field, an RV information field, a HARQ process number information field, and an Antenna port information field.

[0346] In some embodiments, the at least one first information field to be refarmed may include an MCS information field, an NDI information field, an RV information field, and a HARQ process number information field.

[0347] In some embodiments, at least one first information field of refarming may include an MCS information field, an NDI information field, an RV information field, and a HARQ process number information field, wherein, when the type of the antenna port information field is Type-2, the first information field may also include the antenna port information field, and when the type of the antenna port information field is type-1A, the first information field does not include the antenna port information field.

[0348] It should be noted that the re-farming described in the embodiment of the present disclosure refers to the re-farming of an information domain, in which the information domain is not used to implement the original indication function, but is used to implement a new indication function after the re-farming.

[0349] For example, the MCS information field is originally used to indicate the modulation and coding strategy, but after refarming, it is used to indicate the sleep state of the secondary cell. For example, if the proportion of the at least one refarmed first information field is n bits, then the sleep state of n secondary cells can be indicated, wherein there can be a correspondence between the n bits and the n secondary cells, and the i-th bit of the n bits is used to indicate the sleep state of the i-th secondary cell among the n secondary cells. For example, if the i-th bit is 0, it is used to indicate that the secondary cell is in the sleep state, and if the i-th bit is 1, it is used to indicate that the secondary cell is not in the sleep state, wherein i and n are positive integers, and i is less than or equal to n.

[0350] In some embodiments, when it is determined that the downlink control information carries the secondary cell dormancy indication information, at least one first information field corresponding to the refarming of the reference cell in the downlink control information is used by the terminal to determine the dormancy state of the secondary cell.

[0351] Based on the above embodiments, when the downlink control information includes an invalid frequency domain resource allocation (FDRA) information field value, there are three corresponding scenarios: Type 3 hybrid automatic repeat request confirmation (HARQ-ACK), downlink control information carrying secondary cell sleep indication information, and unscheduled cell. For different scenarios, the subsequent operations performed by the terminal may vary, which may lead to the above-mentioned technical problem of erroneous operation.

[0352] For example, the two scenarios of downlink control information carrying secondary cell sleep indication information and cell unscheduled are taken as examples. In the case of the cell unscheduled scenario, the operation performed by the terminal may include not communicating in the unscheduled cell; in the case of the downlink control information carrying secondary cell sleep indication information, the operation performed by the terminal may include determining the sleep state of the secondary cell according to at least one first information field of the recultivated corresponding reference cell in the downlink control information, for example, if the proportion of at least one first information field of the recultivated is n bits, the terminal can determine the sleep state of n secondary cells based on these n bits, that is, determine whether each of the n secondary cells is in the sleep state.

[0353] In some embodiments, the reference cell includes at least one of the following:

[0354] Primary cell Pcell;

[0355] at least one cell among the cells actually scheduled by the downlink control information;

[0356] at least one cell in the cell set corresponding to the downlink control information;

[0357] At least one of the cells corresponding to the invalid FDRA information field value;

[0358] At least one cell used to calculate blind detection information among the cells actually scheduled by the downlink control information.

[0359] In some embodiments, the cell set corresponding to the downlink control information may be a cell set consisting of cells that can be scheduled by the downlink control information. In some embodiments, the blind detection information includes at least one of the following: blind detection (BD) and control channel element (CCE).

[0360] In some embodiments, the reference cell may be one of the cells actually scheduled by the downlink control information, or multiple cells among the cells actually scheduled by the downlink control information. For example, when the reference cell is one of the cells actually scheduled by the downlink control information, the reference cell may be the cell with the smallest ID (which may be referred to as an index) among the cells actually scheduled by the downlink control information, or may be the cell with the largest ID among the cells actually scheduled by the downlink control information. Of course, the present invention is not limited thereto, and the reference cell may also be a cell corresponding to any ID among the cells actually scheduled by the downlink control information.

[0361] In some embodiments, the reference cell may be a cell in the cell set corresponding to the downlink control information, or multiple cells in the cell set. For example, when the reference cell is a cell in the cell set, the cell may be the cell with the smallest identifier in the cell set, or the cell with the largest identifier in the cell set. Of course, the present invention is not limited thereto, and the reference cell may also be a cell corresponding to any identifier in the cell set.

[0362] In some embodiments, the reference cell may be one of the cells corresponding to the invalid FDRA information field value, or multiple cells among the cells corresponding to the invalid FDRA information field value. For example, when the reference cell is one of the cells corresponding to the invalid FDRA information field value, the reference cell may be the cell with the smallest identifier among the cells corresponding to the invalid FDRA information field value; or, the reference cell may be the cell with the largest identifier among the cells corresponding to the invalid FDRA information field value.

[0363] For example, among the four FDRA information fields, the first FDRA information field is used to indicate resource allocation information for Cell#1, the second FDRA information field is used to indicate resource allocation information for Cell#2, the third FDRA information field is used to indicate resource allocation information for Cell#3, and the fourth FDRA information field is used to indicate resource allocation information for Cell#4. When the value of the first FDRA information field is invalid, and the value of the third FDRA information field is invalid, the cells corresponding to the invalid FDRA information field values ​​are Cell#1 and Cell#3. If the reference cell is the cell with the smallest identifier among the cells corresponding to the invalid FDRA information field values, then the reference cell is Cell#1. If the reference cell is the cell with the largest identifier among the cells corresponding to the invalid FDRA information field values, then the reference cell is Cell#3. Of course, this is not limited to this, and the reference cell can also be a cell corresponding to any identifier among the cells corresponding to the invalid FDRA information field values.

[0364] In some embodiments, the first information indication is used for the terminal to determine the scenario, including: the first information is used for the terminal to determine that the scenario is downlink control information carrying cell sleep indication information or cell unscheduled, wherein the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or the value is 0.

[0365] For example, the terminal can first parse the FDRA information field and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. When it is determined that there is an invalid FDRA information field value and the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, there are only two scenarios corresponding to this condition: the downlink control information carries cell sleep indication information and the cell is not scheduled. The terminal can distinguish the scenario corresponding to the condition based on the first information, whether the downlink control information carries cell sleep indication information or the cell is not scheduled.

[0366] In some embodiments, the scenario is one of type 3 hybrid automatic repeat request confirmation and downlink control information carrying secondary cell sleep indication information, and the terminal is instructed to determine type 3 hybrid automatic repeat request confirmation or downlink control information carrying secondary cell sleep indication information through the single hybrid automatic repeat request confirmation indication information field in the downlink control information.

[0367] For example, the terminal may first parse the FDRA information field in the downlink control information. When it is determined that there is an invalid FDRA information field value, there are three scenarios corresponding to this condition: type 3 hybrid automatic repeat confirmation, downlink control information carrying secondary cell sleep indication information, and cell unscheduled. Furthermore, the terminal may try to distinguish the scenarios based on the first information. When it is determined that the cell is unscheduled based on the first information, then there is no need to further distinguish, and the single-shot hybrid automatic repeat request confirmation indication information field may not be parsed; when the first scenario includes one of type 3 hybrid automatic repeat confirmation and downlink control information carrying secondary cell sleep indication information, then it is necessary to further distinguish the scenarios. The terminal may distinguish whether the scenario is type 3 hybrid automatic repeat confirmation or downlink control information carrying secondary cell sleep indication information based on the single-shot hybrid automatic repeat request confirmation indication information field in the downlink control information.

[0368] It can be seen that in some embodiments, the condition described in the embodiments of the present disclosure is only that the downlink control information includes an invalid FDRA information field value. In other embodiments, the condition described in the embodiments of the present disclosure may be that the downlink control information includes an invalid FDRA information field value, and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or the value is 0.

[0369] The following uses several embodiments to exemplify how the first information indication is used for the terminal to determine the scenario.

[0370] In some embodiments, the first information indication is used by the terminal to determine the scenario, including at least one of the following:

[0371] The value of at least one information field is a first value, which is used to indicate that the terminal scenario is cell unscheduled;

[0372] The value of at least one information field is the second value, which is used to indicate that the terminal scenario is downlink control information carrying secondary cell sleep indication information, or one of type 3 hybrid automatic repeat acknowledgement and downlink control information carrying secondary cell sleep indication information.

[0373] In some embodiments, when the first information is the value of at least one other information field other than the FDRA information field in the information field corresponding to the reference cell in the downlink control information, the value of the at least one information field can be determined based on all bits in the at least one first information field.

[0374] For example, when the downlink control information includes an invalid FDRA information field value, and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information and the cell being unscheduled. When the value of at least one information field is a first value, the terminal can distinguish the scenario as specifically that the cell is unscheduled; when the value of at least one information field is a second value, the terminal can distinguish the scenario as specifically that the downlink control information carries cell sleep indication information.

[0375] It should be noted that the first value and the second value can be two different values. The first value in different embodiments can be the same or different, and the second value in different embodiments can be the same or different. For example, the first value can be 0 and the second value can be 1. Of course, it is not limited to this.

[0376] For example, when the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information, the cell being unscheduled, and hybrid automatic repeat request confirmation of type 3. When the value of at least one information field is a first value, the terminal can distinguish that the scenario is specifically that the cell is unscheduled; when the value of at least one information field is a second value, the terminal can distinguish that the scenario is one of the hybrid automatic repeat request confirmation of type 3 and the downlink control information carrying secondary cell sleep indication information.

[0377] In this case, the terminal can further distinguish the scenarios according to the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, it can be determined that the downlink control information carries the secondary cell sleep indication information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field exists and the value is 1, type 3 hybrid automatic repeat confirmation can be determined.

[0378] In some embodiments, the first information indication is used by the terminal to determine the scenario, including at least one of the following:

[0379] The value of at least one bit in the at least one first information field is a first value, used to indicate that the terminal determines that the cell is not scheduled;

[0380] The value of at least one bit in at least one first information field is the second value, which is used by the terminal to determine that the downlink control information carries the secondary cell sleep indication information, or that it is one of type 3 hybrid automatic repeat request confirmation and downlink control information carrying the secondary cell sleep indication information.

[0381] For example, when the downlink control information includes an invalid FDRA information field value, and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information and the cell being unscheduled. When the value of at least one bit in at least one first information field is a first value, the terminal can distinguish that the scenario is specifically that the cell is unscheduled; when the value of at least one bit in at least one first information field is a second value, the terminal can distinguish that the scenario is specifically that the downlink control information carries cell sleep indication information.

[0382] For example, when the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of downlink control information carrying cell sleep indication information, cell unscheduled, and type 3 hybrid automatic repeat request confirmation. When the value of at least one bit in at least one first information field is a first value, the terminal can distinguish that the scenario is specifically that the cell is unscheduled; when the value of at least one bit in at least one first information field is a second value, the terminal can distinguish that the scenario is one of type 3 hybrid automatic repeat request confirmation and downlink control information carrying secondary cell sleep indication information.

[0383] In this case, the terminal can further distinguish the scenarios according to the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, it can be determined that the downlink control information carries the secondary cell sleep indication information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field exists and the value is 1, type 3 hybrid automatic repeat confirmation can be determined.

[0384] In some embodiments, the at least one bit in the at least one first information field corresponding to the reference cell in the downlink control information may be one bit or multiple bits in the proportion of the at least one first information field corresponding to the reference cell in the downlink control information. Specifically, when the at least one bit in the at least one first information field corresponding to the reference cell in the downlink control information is one bit in the proportion of the at least one first information field corresponding to the reference cell in the downlink control information, the bit may be any bit in the proportion of the at least one first information field corresponding to the reference cell in the downlink control information, for example, the first bit, or the last bit, and of course, may also be a bit between the first bit and the last bit.

[0385] For example, when this bit is the first bit in the proportion of at least one first information field in the corresponding reference cell in the downlink control information, the terminal can distinguish the scenarios by parsing the first bit in the proportion of the at least one first information field. Since, in the scenario where the downlink control information carries secondary cell sleep indication information, the at least one first information field in the reference cell is re-farmed to determine the sleep state of the secondary cell, the terminal needs to parse the bits after the first bit to determine the sleep state of the secondary cell. In the scenario where the cell is unscheduled, the terminal can determine that the reference cell is unscheduled, and therefore does not need to further parse the bits after the first bit, which helps save overhead.

[0386] For example, when this bit is the last bit in the proportion of at least one first information field in the corresponding reference cell in the downlink control information, the terminal can distinguish the scenarios by parsing the first bit in the proportion of the at least one first information field. In the case where the scenario is that the downlink control information carries secondary cell sleep indication information, refarming of at least one first information field in the reference cell is used to determine the sleep state of the secondary cell. In the case where refarming is used to determine the sleep state of the secondary cell, an association relationship may exist between the proportion of the at least one first information field in the reference cell and the secondary cell. The association relationship is generally associated with the secondary cell starting from the first bit of the proportion of the at least one first information field. In this case, the scenario is distinguished by the last bit in the proportion of the at least one first information field, and the association relationship between the bits before the last bit and the secondary cell does not need to be adjusted, which helps reduce the overhead of adjusting the mapping relationship.

[0387] In some embodiments, the first information indication is used by the terminal to determine the scenario, including at least one of the following:

[0388] The newly defined information field indicates a first value, which is used to indicate to the terminal that the cell is determined to be unscheduled;

[0389] The newly defined information field indicates a second value, which is used by the terminal to determine whether the downlink control information carries the secondary cell sleep indication information, or whether it is a type 3 hybrid automatic repeat request confirmation and the downlink control information carries the secondary cell sleep indication information.

[0390] For example, when the downlink control information includes an invalid FDRA information field value and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information and the cell being unscheduled. When the newly defined information field indicates a first value, the terminal can distinguish that the scenario is specifically that the cell is unscheduled; when the newly defined information field indicates a second value, the terminal can distinguish that the scenario is specifically that the downlink control information carries cell sleep indication information.

[0391] It should be noted that the newly defined information field may occupy one or more bits. For example, in the case of occupying one bit, the first value may be 0 and the second value may be 1. Of course, it is not limited thereto.

[0392] For example, when the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information, the cell being unscheduled, and hybrid automatic repeat request confirmation of type 3. When the terminal indicates the first value in the newly defined information field, the terminal can distinguish that the scenario is specifically that the cell is unscheduled; when the terminal indicates the second value in the newly defined information field, the terminal can distinguish that the scenario is one of the hybrid automatic repeat request confirmation of type 3 and the downlink control information carrying secondary cell sleep indication information.

[0393] In this case, the terminal can further distinguish the scenarios according to the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, it can be determined that the downlink control information carries the secondary cell sleep indication information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field exists and the value is 1, type 3 hybrid automatic repeat confirmation can be determined.

[0394] In some embodiments, the first information indication is used by the terminal to determine the scenario, including at least one of the following:

[0395] The type of at least one other information field is a first type, which is used to indicate that the terminal determines that the cell is not scheduled;

[0396] The type of at least one other information field is the second type, which is used by the terminal to determine that the downlink control information carries the secondary cell sleep indication information, or is one of type 3 hybrid automatic repeat request confirmation and downlink control information carrying the secondary cell sleep indication information.

[0397] For example, when the downlink control information includes an invalid FDRA information field value, and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information and the cell being unscheduled. When the type of at least one other information field is the first type, the terminal can distinguish that the scenario is specifically that the cell is unscheduled; when the type of at least one other information field is the second type, the terminal can distinguish that the scenario is specifically that the downlink control information carries cell sleep indication information.

[0398] It should be noted that the at least one other information field may include one information field, or include multiple information fields. For example, the information field included in the at least one other information field is not limited to the Antenna port information field, the HARQ process number information field, etc. The first type and the second type include but are not limited to type-1A, type-1B, type-1C, type-2, and type-3. Among them, for the type-1B information field, the downlink control information may include one information field of this type, and the type information may be used to indicate the index of the information combination of at least one scheduled cell; for the type-3 information field, the downlink control information may include one or more information fields of this type, and the type information may be determined as one of type-1A, type-1B, and type-2 by predefinition or network device configuration.

[0399] For example, when the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of downlink control information carrying cell sleep indication information, cell unscheduled, and hybrid automatic repeat request confirmation of type 3. When the type of at least one other information field is the first type, the terminal can distinguish the scenario as specifically cell unscheduled; when the type of at least one other information field is the second type, the terminal can distinguish the scenario as one of type 3 hybrid automatic repeat request confirmation and downlink control information carrying secondary cell sleep indication information.

[0400] In this case, the terminal can further distinguish the scenarios according to the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, it can be determined that the downlink control information carries the secondary cell sleep indication information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field exists and the value is 1, type 3 hybrid automatic repeat confirmation can be determined.

[0401] In some embodiments, the first information indication is used by the terminal to determine the scenario, including at least one of the following:

[0402] The value of the FDRA information field corresponding to the reference cell in the downlink control information is invalid, and is used by the terminal to determine that the downlink control information carries the secondary cell sleep indication information, or is one of type 3 hybrid automatic repeat confirmation and the downlink control information carries the secondary cell sleep indication information.

[0403] For example, under the condition that the downlink control information includes an invalid FDRA information field value, and the single-transmitted hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information and the cell being unscheduled. The terminal can distinguish the scenarios based on the value of the FDRA information field of the reference cell, wherein, when the value of the FDRA information field of the reference cell is invalid, the terminal can determine that the scenario is specifically the downlink control information carrying cell sleep indication information. It should be noted that the rule for distinguishing scenarios is pre-defined (for example, protocol agreement or network configuration), and the terminal determines that the scenario is specifically the downlink control information carrying cell sleep indication information when the single-transmitted hybrid automatic repeat request confirmation indication information field does not exist or has a value of 0, and the value of the FDRA information field of the reference cell is invalid, and will not distinguish the scenarios based on the value of the FDRA information field of other cells.

[0404] For example, when the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information, cell unscheduled, and type 3 hybrid automatic repeat confirmation. The terminal can distinguish the scenarios based on the value of the FDRA information field of the reference cell, wherein, when the value of the FDRA information field of the reference cell is invalid, the terminal can determine one of type 3 hybrid automatic repeat confirmation and downlink control information carrying secondary cell sleep indication information. It should be noted that the rule for distinguishing the scenarios is pre-defined (for example, protocol agreement or network configuration), and the terminal will determine one of type 3 hybrid automatic repeat confirmation and downlink control information carrying secondary cell sleep indication information only when the value of the FDRA information field of the reference cell is invalid, and will not distinguish the scenarios based on the value of the FDRA information field of other cells.

[0405] In this case, the terminal can further distinguish the scenarios according to the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, it can be determined that the downlink control information carries the secondary cell sleep indication information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field exists and the value is 1, type 3 hybrid automatic repeat confirmation can be determined.

[0406] In some embodiments, the first information indication is used by the terminal to determine the scenario, including at least one of the following:

[0407] The number of cells corresponding to the invalid FDRA information field value and the number threshold satisfy a first relationship, which is used by the terminal to determine that the downlink control information carries the secondary cell sleep indication information, or is one of type 3 hybrid automatic repeat confirmation and downlink control information carrying the secondary cell sleep indication information;

[0408] The number of cells corresponding to the invalid FDRA information field does not satisfy the first relationship with the number threshold, which is used to indicate that the terminal determines that the cell is not scheduled.

[0409] For example, when the downlink control information includes an invalid FDRA information field value, and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information and the cell being unscheduled. The terminal can distinguish the scenarios based on the number of cells corresponding to the invalid FDRA information field value, wherein, when the number of cells corresponding to the invalid FDRA information field value and the quantity threshold do not satisfy the first relationship, the scenario can be distinguished as specifically the cell being unscheduled; when the number of cells corresponding to the invalid FDRA information field value and the quantity threshold satisfy the first relationship, the terminal can distinguish the scenario as specifically the downlink control information carrying cell sleep indication information.

[0410] It should be noted that the quantity threshold and / or the first relationship can be determined based on the protocol agreement or configured by the network device, wherein the quantity threshold can be a value greater than or equal to 1, for example, it can be 2, and the first relationship can be, for example, the quantity is greater than the quantity threshold, or it can be the quantity is less than the quantity threshold, and there is no restriction on this.

[0411] For example, when the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information, cell unscheduled, and type 3 hybrid automatic repeat confirmation. The terminal can distinguish the scenarios based on the number of cells corresponding to the invalid FDRA information field value, wherein, when the number of cells corresponding to the invalid FDRA information field value and the number threshold do not satisfy the first relationship, the scenario can be distinguished as specifically cell unscheduled; when the number of cells corresponding to the invalid FDRA information field value and the number threshold satisfy the first relationship, the terminal can distinguish the scenario as type 3 hybrid automatic repeat confirmation and downlink control information carrying secondary cell sleep indication information.

[0412] In this case, the terminal can further distinguish the scenarios according to the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, it can be determined that the downlink control information carries the secondary cell sleep indication information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field exists and the value is 1, type 3 hybrid automatic repeat confirmation can be determined.

[0413] In some embodiments, the first information indication is used by the terminal to determine the scenario, including at least one of the following:

[0414] The information used to determine the actual scheduling cell of the downlink control information does not include the FDRA information field, and is used by the terminal to determine that the downlink control information carries the secondary cell sleep indication information, or is one of type 3 hybrid automatic repeat acknowledgement and downlink control information carrying the secondary cell sleep indication information;

[0415] The information used to determine the actual scheduling cell of the downlink control information includes an FDRA information field, which is used to indicate to the terminal that the cell is not scheduled.

[0416] In some embodiments, there are two ways to determine the actual scheduled cell of the downlink control information, one of which is to determine the actual scheduled cell of the downlink control information based on the FDRA information field; the other is to first receive a scheduled cell combination list (ScheduledCellCombo-List) through RRC signaling, for example, for DCI 0_3, it may be ScheduledCellCombo-ListDCI-0-3, for DCI 1_3, it may be ScheduledCellCombo-ListDCI-1-3, and then determine the cell combination as the actual scheduled cell in the list based on the information field scheduled cell indicator (field scheduled cell indicator) in the downlink control information.

[0417] Among them, when the RRC signaling is configured with a scheduling cell combination list, the terminal can determine that the information used to determine the actual scheduling cell of the downlink control information does not include the FDRA information field. When the RRC signaling is not configured with a scheduling cell combination list, it can determine that the information used to determine the actual scheduling cell of the downlink control information includes the FDRA information field.

[0418] For example, when the downlink control information includes an invalid FDRA information field value, and the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information and the cell being unscheduled. When the information used to determine the cell actually scheduled by the downlink control information includes the FDRA information field, the terminal can distinguish the scenario as specifically that the cell is unscheduled; when the information used to determine the cell actually scheduled by the downlink control information does not include the FDRA information field, the terminal can distinguish the scenario as specifically that the downlink control information carries cell sleep indication information.

[0419] For example, when the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of the downlink control information carrying cell sleep indication information, the cell being unscheduled, and hybrid automatic repeat acknowledgement of type 3. When the information used to determine the actual scheduling cell of the downlink control information includes the FDRA information field, the terminal can distinguish the scenario as specifically the cell being unscheduled; when the information used to determine the actual scheduling cell of the downlink control information does not include the FDRA information field, the terminal can distinguish the scenario as one of the type 3 hybrid automatic repeat acknowledgement and the downlink control information carrying secondary cell sleep indication information.

[0420] In this case, the terminal can further distinguish the scenarios according to the single-transmission hybrid automatic repeat request confirmation indication information field in the downlink control information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field does not exist or the value is 0, it can be determined that the downlink control information carries the secondary cell sleep indication information. For example, under the condition that the single-transmission hybrid automatic repeat request confirmation indication information field exists and the value is 1, type 3 hybrid automatic repeat confirmation can be determined.

[0421] In some embodiments, the terminal may be a Rel-18 or later version terminal, and the terminal may receive DCI for multi-cell scheduling, and based on indication information corresponding to the DCI, receive PDSCHs of multiple cells or transmit PUSCHs of multiple cells;

[0422] In some embodiments, the DCI that schedules multiple cell data may be referred to as MC DCI. For example, the DCI that schedules multiple cell PUSCHs is referred to as DCI 0_3, and the DCI that schedules multiple cell PDSCHs is referred to as DCI 1_3.

[0423] The FDRA field of MC DCI belongs to type 2 type field, that is, for different cells, different FDRA fields are used to indicate the scheduling status of different cells. Among them, under the condition that ScheduledCellCombo-ListDCI 0_3 is not configured or ScheduledCellCombo-List DCI 1_3 is not configured, MC DCI indicates the scheduling status of the cell based on different FDRA fields. Specifically including: if the FDRA field value corresponding to cell 1 is invalid, the terminal determines that cell 1 is not scheduled, corresponding to scenario 3 (that is, the cell is not scheduled). The invalid FDRA is described in the previous embodiment.

[0424] Considering that the FDRA value corresponding to cell 1 is invalid, and the one shot HARQ-ACK indicator field corresponding to MC DCI does not exist or the indication value is 0, the terminal re-cultivates the existing field to obtain the corresponding Scell ​​dormancy information, corresponding to scenario 2 (that is, the downlink control information carries the secondary cell dormancy indication information).

[0425] The core of scenario 2 and scenario 3 is whether the terminal needs to further read the repurpose field to obtain the corresponding Scell ​​dormancy information. The repurpose field includes one or more of the following fields:

[0426] Modulation and coding scheme of transport block 1

[0427] New data indicator of transport block 1

[0428] Redundancy version of transport block 1

[0429] HARQ process number

[0430] Antenna port(s)

[0431] DMRS sequence initialization

[0432] For scenario 2 and scenario 3, the terminal distinguishes between scenario 2 and scenario 3 in the following embodiment.

[0433] Embodiment 1: introducing an additional information field or information bit (eg, a newly defined information field or a newly defined bit) to distinguish the two scenarios.

[0434] Example 1-1: The terminal distinguishes the two scenarios based on the antenna port field of cell 1. For example, if the antenna port field of cell 1 is configured as type 1a, then the corresponding cell 1 is scenario 3; if the antenna port field of cell 1 is configured as type 2, then the corresponding cell 1 is scenario 2.

[0435] Embodiment 1-2: The domain may be one or more of the above-mentioned repurpose fields. If the bits indicated by all fields are 0, it corresponds to scenario 3; otherwise, it corresponds to scenario 2. Alternatively, if the bits indicated by all fields are 1, it corresponds to scenario 3; otherwise, it corresponds to scenario 2.

[0436] Embodiment 1-3: A new information field is added, the field occupies 1 bit, and exemplarily, if the field indicates 0, it corresponds to scenario 3; otherwise, it corresponds to scenario 2. Alternatively, exemplarily, if the field indicates 1, it corresponds to scenario 3; otherwise, it corresponds to scenario 2.

[0437] Embodiment 1-4: The domain may be an information domain corresponding to type 2 in the MC DCI and corresponding to cell 1, and the domain may include one or more of the following:

[0438] domains corresponding to TB1 and / or TB2;

[0439] Modulation and coding scheme;

[0440] New data indicator;

[0441] Redundancy version;

[0442] HARQ process number,antenna port(type 2);

[0443] Exemplarily, if the first bit in the TB 1 MCS, or the first bit in the TB 2 MCS, or the NDI field of TB 1, or the NDI field of TB 2 indicates 0, it corresponds to scenario 3; otherwise, it corresponds to scenario 2. Alternatively, exemplarily, if the field (bit) indicates 1, it corresponds to scenario 3; otherwise, it corresponds to scenario 2.

[0444] Example 1-5: The bit may be the first bit of all fields used for Scell ​​dormancy corresponding to cell 1, e.g., the first bit of the MCS corresponding to TB1 of cell 1, or the bit may be the last bit of all fields used for Scell ​​dormancy corresponding to cell 1, for example, DMRS sequence initialization, or the last bit of the antenna port(s) corresponding to cell 1 (e.g., if the antenna port(s) is configured as type 2, note: it can also be decoupled from the scenario of e.g.,), or the last bit of the HARQ process number corresponding to cell 1 (e.g., if the antenna port(s) is configured as type 1a, note: it can also be decoupled from the scenario of e.g.,). The method does not require changing the mapping order of the Scell ​​dormancy bit and the repurpose field.

[0445] Based on embodiment 1, when there are multiple cells 1 in scenario 2, the terminal determines the corresponding Scell ​​dormancy information based only on the indication information of the reference cell. Exemplarily, the reference cell is the cell with the smallest cell ID among the multiple cells 1; or, the reference cell is the cell 1 with the smallest cell ID in the cell set and that meets the above conditions; or, the reference cell is the Pcell cell;

[0446] Embodiment 2: Define a reference cell. Only when the FDRA on the reference cell is invalid and the corresponding one-shot HACQ-ACK indicator does not exist or indicates 0, the terminal will indicate the corresponding Scell ​​dormancy information based on the repurpose field corresponding to the reference cell. The repurpose field has been given in Embodiment 1 and will not be repeated here.

[0447] Example 2-1: The reference cell is the cell with the smallest cell ID in the cell set.

[0448] Embodiment 2-2: The reference cell is the cell with the smallest / largest cell ID among at least one cell corresponding to invalid FDRA;

[0449] Example 2-3: The reference cell is a Pcell cell.

[0450] Embodiment 3: A first condition is defined. As long as the one shot HACQ-ACK indicator does not exist or indicates 0, and the first condition is met, the terminal parses the corresponding Scell ​​dormancy information based on the reference cell.

[0451] The first condition includes:

[0452] Example 3-1: Determine the number N of cells corresponding to invalid FDRA, N is greater than the first parameter, or N is less than the first parameter;

[0453] The first parameter is determined based on a signaling indication or a predefined manner. Exemplarily, the first parameter is equal to 2;

[0454] The reference cell is the cell with the smallest cell ID among at least one cell that meets invalid FDRA.

[0455] Example 4: Case 2 is adopted only when the terminal does not determine the cell indication scenario based on FDRA. For example, the terminal determines the corresponding Scell ​​dormancy information based on the reference cell only when ScheduledCellCombo-ListDCI-0-3 or ScheduledCellCombo-ListDCI-1-3 is not configured, and the following conditions are met on the reference cell: invalid FDRA, one shot HACQ-ACK indicator does not exist or is indicated as 0. The reference cell is:

[0456] Embodiment 4-1: The reference cell is one or more cells belonging to the scheduling indicated by the MC DCI, and the scheduled cell is indicated based on a field scheduled cell indicator;

[0457] Embodiment 4-2: The reference cell is one or more cells in the cell set corresponding to the MC DCI;

[0458] Embodiment 4-3: The reference cell is one or more unscheduled cells indicated by the MC DCI, and the terminal determines whether the cell is scheduled based on a field scheduled cell indicator;

[0459] Embodiment 4-4: The reference cell is the cell with the smallest / largest corresponding cell ID among the cells that meet at least one of the three conditions described in Embodiments 4-1 to 4-3.

[0460] It can be seen that the main design rule of this embodiment is to determine different indication scenarios under the condition of invalid FDRA, which is conducive to reducing the processing complexity of the terminal and achieving consistent understanding between the base station and the terminal.
