[0091] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0092] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0093] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 .

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0095] In some embodiments, the network device may send downlink control information to the terminal. The difference from the legacy downlink control information is that the downlink control information in the embodiments of the present disclosure can schedule multiple cells.

[0096] For example, the downlink control information described in the embodiments of the present disclosure may be referred to as multi-cell scheduling downlink control information (MC-DCI).

[0097] For example, MC-DCI may be used to schedule physical downlink shared channels (PDSCH) and physical uplink shared channels (PUSCH) of multiple cells.

[0098] In some embodiments, the format of MC-DCI may be different from the format of legacy DCI. For example, MC-DCI includes, but is not limited to, DCI 0_3 for scheduling the PUSCH of multiple cells and DCI 1_3 for scheduling the PDSCH of multiple cells. Legacy DCI formats include, but are not limited to, DCI 0_0, DCI 0_1, DCI 1_0, DCI 1_1, DCI 2_0, and DCI 2_1.

[0099] In some embodiments, the conventional DCI may be used to indicate the dormancy state of the scheduled cell, for example, to indicate the dormancy state of a secondary cell (Scell ​​dormancy indication).

[0100] In some embodiments, the information field in DCI 1_1 in the traditional DCI may be used to indicate the dormant state of the scheduled cell.

[0101] For example, a specific information field may be set in DCI 1_1, such as a secondary cell dormancy indication (Scell ​​dormancy indication) information field. This information field may indicate the dormancy status of cells in a cell group with a cell group as the granularity.

[0102] For example, when the cell scheduled by DCI 1_1 meets the information field refarming condition, the information field in DCI 1_1 can be refarmed to indicate the dormant state of the cell.

[0103] The information domain refarming conditions include at least one of the following:

[0104] The value of the frequency domain resource allocation information field corresponding to the first cell is invalid (invalid);

[0105] The one-shot HARQ (Hybrid Automatic Repeat reQuest) ACK information field does not exist or has a value of 0;

[0106] The HARQ-ACK retransmission indicator field does not exist or has a value of 0.

[0107] DCI 1_1 is transmitted on the primary cell;

[0108] The Carrier Indication Field (CIF) in DCI 1_1 does not exist or has a value of 0.

[0109] The information field that can be re-farmed in DCI 1_1 to indicate the dormant state of the cell includes at least one of the following:

[0110] New Data Indicator (NDI) information field;

[0111] Modulation and Coding Scheme (MCS) information field;

[0112] Redundancy version (RV) information field;

[0113] Hybrid automatic repeat request process number (HARQ process number) information field;

[0114] Antenna port (antenna port(s)) information field;

[0115] Demodulation Reference Signal sequence initialization (DMRS (Demodulation Reference Signal) sequence initialization) information field.

[0116] When MC-DCI is introduced, it is also necessary to consider indicating the dormant state of the secondary cell through MC-DCI.

[0117] FIG2 is an interactive schematic diagram showing a method for receiving information according to an embodiment of the present disclosure.

[0118] As shown in FIG2 , the information receiving method may include the following steps:

[0119] Step S201: The terminal receives downlink control information sent by the network device.

[0120] In some embodiments, downlink control information can schedule multiple cells.

[0121] For example, the downlink control information may be referred to as multi-cell scheduling downlink control information. To simplify the description, the following embodiments are mainly described using MC-DCI instead of the downlink control information in the present disclosure.

[0122] It should be noted that MC-DCI can schedule multiple cells, but the cell actually scheduled by MC-DCI can be one cell or multiple cells. The cell actually scheduled by MC-DCI belongs to the cells that MC-DCI can schedule.

[0123] In step S202, the terminal determines the dormancy state of at least one first cell according to the downlink control information, wherein the dormancy state of the first cell includes one of the following: dormancy and non-dormancy.

[0124] In some embodiments, the terminal may determine the dormant state of at least one first cell according to a first information field (also referred to as a field) in the MC-DCI.

[0125] For example, the at least one first cell may be all or part of the cells actually scheduled by the MC-DCI.

[0126] For example, the first cell may be a primary cell (Pcell), a secondary cell (Scell), or other types of cells, which is not limited in the present disclosure.

[0127] It should be noted that when the first cell meets the conditions for indicating cell dormancy based on information field refarming (also referred to as information field refarming conditions or refarming conditions), the first information field in the MC-DCI can be used to indicate the dormant state of the first cell. The conditions for indicating cell dormancy based on information field refarming include at least one of the following:

[0128] The value of the frequency domain resource allocation information field corresponding to the first cell is invalid (invalid);

[0129] The one shot HARQ ACK information field does not exist or has a value of 0;

[0130] The HARQ-ACK retransmission indicator information field does not exist or has a value of 0;

[0131] MCC-DCI is transmitted on the primary cell.

[0132] According to the embodiments of the present disclosure, the network device can indicate the dormant state of the cell to the terminal through the information field in the MC-DCI, ensuring that when MC-DCI is introduced, the network device can also indicate the dormant state of the cell through MC-DCI.

[0133] In some embodiments, since MC-DCI can schedule multiple cells, the information field in MC-DCI can also schedule multiple cells.

[0134] Among them, some information fields in MC-DCI can schedule each cell actually scheduled by MC-DCI through one information field, and some information fields have a corresponding relationship with the cell and can only schedule the corresponding cell.

[0135] For example, the type of the information field in the MC-DCI may include a first type (e.g., type 1a, also known as type-1a), a second type (e.g., type 2, also known as type-2), etc. The following embodiments mainly illustrate the technical solutions of the present disclosure by exemplifying the first type as type-1a and the second type as type-2.

[0136] Among them, MC-DCI can include multiple type-1a information fields, but for each type-1a information field, MC-DCI only includes one type-1a information field, and one type-1a information field indicates scheduling information for each cell that actually schedules downlink control information.

[0137] For example, MC-DCI may include multiple type-1a information fields such as antenna port(s) and DMRS sequence initialization. However, for example, for the DMRS sequence initialization information field, MC-DCI only includes one DMRS sequence initialization information field, and DMRS sequence initialization may indicate DMRS sequence information for each cell scheduled by MC-DCI.

[0138] Among them, MC-DCI can include multiple type-2 information fields, and for one type-2 information field, MC-DCI can include multiple, and the type-2 information field is used to indicate scheduling information for the cell corresponding to the type-2 information field in the cell scheduled by MC-DCI.

[0139] For example, MC-DCI may include multiple type-2 information fields such as NDI and MCS. For example, for the MCS information field, MC-DCI includes n MCS information fields. The i-th MCS information field among the n MCS information fields corresponds to the i-th cell among the n cells scheduled by MC-DCI. The i-th MCS information field is used to indicate MCS information for the i-th cell.

[0140] It should be understood that the type of the information field in MC-DCI is not limited to the above-mentioned type-1a and type-2, and other types of information fields may also exist, which is not limited by the present disclosure.

[0141] The following describes the differences between the type-1a information field and the type-2 information field through several embodiments.

[0142] For example, the type-2 information field in the MC-DCI may include a frequency domain resource allocation (FDRA) information field, an NDI information field, an MCS information field, an RV information field, a HARQ process number information field, and the like.

[0143] Taking the FDRA information field, a type-2 information field, as an example, MC-DCI may include n FDRA information fields, namely FDRA#1, FDRA#2, ..., FDRA#n. The n FDRA information fields correspond to n cells. Specifically, FDRA#1 corresponds to cell#1, FDRA#2 corresponds to cell#2, ..., and FDRA#n corresponds to cell#n. Thus, FDRA#1 indicates scheduling information only for cell#1, FDRA#2 indicates scheduling information only for cell#2, ..., and FDRA#n indicates scheduling information only for cell#n.

[0144] For example, the HARQ-ACK retransmission indicator information field in the MC-DCI is a type-1a information field.

[0145] MC-DCI includes only one HARQ-ACK retransmission indicator information field. For example, if the MC-DCI actually schedules m cells, the HARQ-ACK retransmission indicator information field can be used to indicate scheduling information for each of the m cells. That is, the scheduling information indicated by the HARQ-ACK retransmission indicator information field applies to each of the m cells. For example, if the HARQ-ACK retransmission indicator information field indicates HARQ-ACK retransmission, the terminal can determine that HARQ-ACK retransmission is required in each of the m cells.

[0146] It should be noted that m, n, and i in the above embodiments are positive integers.

[0147] In some embodiments, the first information field in the MC-DCI for indicating the dormant state of at least one first cell may include a type-2 information field or a type-1a information field.

[0148] Since the first information domain itself has the function of indicating scheduling information, in order to indicate the dormant state of the cell through the first information domain, the first information domain needs to be refarmed. Therefore, the first cell can only indicate the dormant state of the first cell area through the first information domain when the conditions for indicating cell dormancy based on information domain refarming are met.

[0149] Among them, when the type-1a information field in MC-DCI is used as the first information field to indicate the sleep state of at least one first cell, since the type-1a information field itself also needs to indicate scheduling information for each cell actually scheduled by MC-DCI, the type-1a information field needs to indicate two types of information (sleep state and scheduling information) for each cell actually scheduled by MC-DCI, which will lead to technical problems such as reducing the scheduling flexibility and scheduling performance of network equipment.

[0150] In some embodiments, the first information field does not include a first type of information field.

[0151] In this embodiment, when MC-DCI is used to indicate the sleep state of the first cell, the sleep state of the first cell can be indicated by an information field other than type1-a in MC-DCI (for example, type-2, etc.), instead of indicating the sleep state of the first cell through the information field of type1-a in MC-DCI, thereby avoiding the problem caused by the need for the above-mentioned type-1a information field to indicate two types of information for each cell.

[0152] For example, the sleep state of the first cell is indicated by the type-2 information field in the MC-DCI. For a certain type-2 information field, the MC-DCI may include multiple such type-2 information fields (for example, multiple FDRA information fields). Therefore, when the sleep state of the first cell is indicated by the type-2 information field in the MC-DCI, only some of the multiple type-2 information fields can be refarmed to indicate the sleep state of the first cell. For example, the type-2 information field corresponding to the cell not scheduled by the MC-DCI, or the invalid type-2 information field, can be refarmed to indicate the sleep state of the first cell. Then there will be no problem that the above-mentioned one information field needs to indicate two types of information for the first cell.

[0153] It should be noted that, in this embodiment, even if the first cell meets the conditions for indicating cell dormancy based on information field refarming, the dormancy state of the first cell will not be indicated through the type-1a information field.

[0154] For example, the type-1a information field includes at least one of the following:

[0155] antenna port(s) information field;

[0156] DMRS sequence initialization information field.

[0157] The type of antenna port(s) may be type-1a or type-2, and the network device may indicate whether the type of antenna port(s) is type-1a or type-2, for example, through radio resource control (RRC) signaling.

[0158] It should be noted that the information field of type-1a is not limited to the above-mentioned antenna port(s) information field and DMRS sequence initialization information field. MD-DCI may also include other type-1a information fields, such as HARQ-ACK retransmission indicator, one shot HARQ ACK, etc., which is not limited in this disclosure.

[0159] When the first information field does not include the first type of information field, for example, MC-DCI includes the antenna port(s) information field, if the type of the antenna port(s) is type-1a, then the antenna port(s) information field is not used to indicate the sleep state of the first cell.

[0160] In a case where the first information field does not include the first type of information field, for example, the MC-DCI includes the DMRS sequence initialization information field, then the DMRS sequence initialization information field is not used to indicate the dormant state of the first cell.

[0161] For example, when the first information field does not include the information field of the first type, the cells actually scheduled by MC-DCI are cell#1, cell#3, and cell#4, among which cell#1 and cell#3 meet the conditions for indicating cell dormancy based on information field refarming. The terminal can determine the dormancy status of cell#1 and cell#3 based on the information field of a type other than type-1a (for example, type-2) in MC-DCI.

[0162] The above describes, through several embodiments, the case where the first information field does not include the type-1a information field. The following describes, through several embodiments, the case where the first information field includes the type-1a information field.

[0163] As for whether the first information field includes the type-1a information field, the terminal can determine it according to the instruction information of the network device.

[0164] For example, in some embodiments, the terminal may receive indication information sent by the network device, where the indication information is used to indicate whether the first information field includes a type-1a information field.

[0165] When the indication information indicates that the first type of information field is not included, the terminal can determine that the type-1a information field in the MC-DCI is not used to indicate the sleep state of the first cell; when the indication information indicates that the first type of information field is not included, the terminal can determine that the type-1a information field in the MC-DCI is used to indicate the sleep state of the first cell.

[0166] In some embodiments, the first cell meets the conditions for indicating cell dormancy based on information field refarming. When the first cell meets this condition, the information field in MC-DCI used to indicate scheduling information for the first cell can be refarmed, so that the network device can indicate the scheduling information of the first cell through the first information field in MC-DCI.

[0167] In some embodiments, the terminal may send capability information to the network device, wherein the capability information is used to indicate whether the terminal supports the type-1a information field for indicating the sleep state of the first cell. The network device may choose to set the information field for indicating the sleep state of the first cell in the MC-DCI based on the capability information.

[0168] For example, the network device determines based on the capability information that the terminal supports the type-1a information field for indicating the sleep state of the first cell. It can choose to indicate the sleep state of the first cell through the type-1a information field in the MC-DCI, or it can indicate the sleep state of the first cell through an information field of a type other than type-1a in the MC-DCI.

[0169] For example, the network device determines based on the capability information that the terminal supports the type-1a information field for indicating the sleep state of the first cell, and can choose to indicate the sleep state of the first cell through an information field of a type other than type-1a in the MC-DCI.

[0170] In some embodiments, the network device may also determine the information field in the MC-DCI for indicating the dormant state of the first cell based on other information.

[0171] For example, if the network device determines that there are many first cells that need to indicate the sleep state among the first cells actually scheduled by MC-DCI, it can choose to indicate the sleep state of the first cells using the type-1a information field in the MC-DCI, thereby instructing the terminal that the first information field includes the type-1a information field. This helps reduce the complexity of indicating the sleep state of the first cells.

[0172] For example, if the network device determines that there are relatively few first cells that require sleep status indication among the first cells actually scheduled by MC-DCI, the sleep status indication of these first cells can be completed using the type-2 information field, and the terminal can be instructed that the first information field does not include the type-1a information field. Accordingly, the relevant settings required to indicate the sleep status of the first cell using the type-1a information field can be avoided.

[0173] In some embodiments, the terminal may determine whether to determine the sleep state of the first cell based on the type-1a information field based on the relationship between the number of first cells required to indicate the sleep state and the sum of the proportions of the type-2 information field used to indicate the sleep state.

[0174] For example, if the number of first cells required to indicate the sleep state is greater than the total proportion of the type-2 information field used to indicate the sleep state, the terminal may determine the sleep state of the first cell based on the type-1a information field.

[0175] For example, the number of first cells required to indicate the sleep state is less than or equal to the sum of the proportions of the type-2 information fields used to indicate the sleep state. The terminal can determine that the type-1a information field is not used to indicate the sleep state of the first cell, but determines the sleep state of the first cell based on the type-2 information field indicating the sleep state.

[0176] In some embodiments, the condition for indicating cell dormancy based on information domain refarming includes at least one of the following:

[0177] The value of the frequency domain resource allocation information field corresponding to the first cell is invalid (invalid);

[0178] A slotted hybrid automatic repeat request confirmation information field does not exist or has a value of 0;

[0179] The HARQ Confirmation Retransmission Indication field does not exist or has a value of 0;

[0180] Downlink control information is transmitted on the primary cell.

[0181] In some embodiments, the value of the FDRA information field is invalid, including at least one of the following:

[0182] When the signaling indicates that 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);

[0183] When the signaling indicates that the resource allocation type is Type 1, all bits in the FDRA information field are set to 1 (all 1 for type 1).

[0184] In the case where the signaling indicates dynamic, if the DCI indicates that the corresponding resource allocation type is type 0 (Type0), the value of all bits in the FDRA information field is 0; if the DCI indicates that the corresponding resource allocation type is type 1 (Type1), the value of all bits in the FDRA information field is 1 (0 or 1 for dynamic).

[0185] In some embodiments, when the first cell meets the above-mentioned conditions for indicating cell dormancy based on information field refarming, one or more information fields in MC-DCI can be used to indicate the dormancy state of the first cell. In this case, the terminal can determine the dormancy state of the first cell based on the first information field corresponding to the first cell in MC-DCI.

[0186] For example, the information field for indicating the dormant state of the first cell in the MC-DCI may include at least one of the following:

[0187] MCS information field, NDI information field, RV information field, HARQ process number information field, Antenna port(s) information field, DMRS sequence initialization information field.

[0188] For example, when the first information field includes the type-1a information field, the terminal can determine the sleep state of the first cell based on the type-1a information field in the MC-DCI (for example, at least one of the DMRS sequence initialization information field and the type-1a Antenna port(s) information field).

[0189] For example, when the first information field does not include the type-1a information field, the terminal may determine the sleep state of the first cell according to the type-2 information field in the MC-DCI, for example, according to at least one of the following information fields:

[0190] MCS information domain;

[0191] NDI information field;

[0192] RV information field;

[0193] HARQ process number information field;

[0194] Type-2 Antenna port(s) information field (for example, the terminal determines that the type of the Antenna port(s) information field is type-2 based on the indication of the network device).

[0195] It should be noted that the information fields such as the MCS information field, the NDI information field, and the RV information field may be information fields corresponding to transport blocks (TBs), such as the information fields corresponding to TB1 or the information fields corresponding to TB2.

[0196] In some embodiments, the first information field includes a first information field of a first type.

[0197] In this embodiment, the sleep state of the first cell can be indicated by the type-1a information field in the MC-DCI. However, as analyzed above, in this case, the type-1a information field needs to indicate two types of information for each cell actually scheduled by the MC-DCI, which may cause some technical problems. Therefore, some optimization is needed to avoid the type-1a information field indicating two types of information for each cell actually scheduled by the MC-DCI, thereby avoiding the above-mentioned technical problems of reducing the scheduling flexibility and scheduling performance of the network equipment.

[0198] In some embodiments, the terminal may perform at least one of the following operations:

[0199] Ignore the first scheduling information indicated by the first information field for the first cell;

[0200] determining first scheduling information according to the first value;

[0201] The first scheduling information is determined according to bits outside the first information field in the downlink control information.

[0202] In some embodiments, when the first information field of type-1a in MC-DCI is used to indicate the sleep state of the first cell, the terminal can ignore the first scheduling information indicated by the first information field of type-1a for the first cell. Then the first information field of type-1a is only used to indicate the sleep state of the first cell, and is not used to indicate the first scheduling information of the first cell, thereby avoiding the above-mentioned problem of one type-1a information field indicating two kinds of information for the first cell.

[0203] For example, taking the DMRS sequence initialization information field as an example, the first scheduling information indicated by the DMRS sequence initialization information field before refarming is the DMRS sequence information. When the DMRS sequence initialization information field is used to indicate the dormant state of the first cell, the terminal can determine whether the first cell is dormant based on the DMRS sequence initialization information field, and ignore the DMRS sequence information indicated by the DMRS sequence initialization information field for the first cell, so that the DMRS sequence initialization information field only indicates the dormant state for the first cell, but does not indicate the DMRS sequence information.

[0204] In some embodiments, when the first information field of type-1a in the MC-DCI is used to indicate the dormant state of the first cell, the terminal may determine the first scheduling information according to the first value.

[0205] For example, the first value is determined based on a protocol agreement, or the first value is determined based on an instruction of a network device, or the first value is determined based on a capability of the terminal.

[0206] The first value may not be the value indicated by the first information field of type-1a, and the first value may be a value determined based on a predefined method (which may be a method agreed upon in a protocol or a method indicated by a network device). For example, the first value may be any value among the values ​​that can be indicated by the first information field of type-1a; for example, the first value may be the maximum value among the values ​​that can be indicated by the first information field of type-1a; for example, the first value may be the minimum value among the values ​​that can be indicated by the first information field of type-1a; for example, the first value is a value indicated by the network device to the terminal through RRC signaling.

[0207] Accordingly, it can be ensured that when the first information field of type-1a indicates the sleep state of the first cell, the terminal can also determine the first scheduling information that can be indicated by the first information field of type-1a before refarming according to the first value.

[0208] For example, the first value is a value indicated by RRC signaling, and the terminal may determine the first value according to the RRC signaling received on the first cell, or the terminal may determine the first value according to the RRC signaling received on the second cell.

[0209] For example, the second cell may be the cell with the smallest cell identifier outside the first cell, or the second cell may be the cell with the largest cell identifier outside the first cell, or the second cell may be the cell used to calculate the MC-DCI size among the cells that can be scheduled by MC-DCI, or the second cell may be the cell used to calculate the blind detection resources among the cells that can be scheduled by MC-DCI, wherein the blind detection resources include at least one of the following: blind detection (BD) and control channel element (CCE).

[0210] For example, taking the first information field of type-1a as the DMRS sequence initialization information field as an example, the first value can be the value that the DMRS sequence initialization information field can indicate, such as one of {0,1}; or, the first value can be the minimum value that the DMRS sequence initialization information field can indicate, such as 0; or, the first value can be the maximum value that the DMRS sequence initialization information field can indicate, such as 1.

[0211] For example, taking the 4-bit antenna port(s) information field as the first information field of type-1a, the first value may be a value that can be indicated by the antenna port(s), such as one of {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}; or, the first value may be the minimum value that can be indicated by the antenna port(s) information field, such as 0; or, the first value may be the maximum value that can be indicated by the antenna port(s) information field, such as 15. In the case where the antenna port(s) information field occupies 5 bits, the maximum value that can be indicated by the antenna port(s) information field may be 31.

[0212] The first value may also be a value that cannot be indicated by the first information field of type-1a. In this case, the first value is associated with the first scheduling information, and the terminal may determine the first scheduling information indicated by the first value based on the association.

[0213] In some embodiments, the bits of the first information field may be associated with at least one first cell. For example, the first information field includes k bits, there are k reference cells, and the i-th bit among the k bits can be used to indicate the sleep state of the i-th first cell among the k first cells.

[0214] For example, when the at least one first cell is four first cells, the four first cells may be sorted from largest to smallest or from smallest to largest according to the cell identifiers.

[0215] Taking the 4-bit Antenna port(s) information field as an example, for example, the value of the Antenna port(s) information field is 1000.

[0216] If 1 indicates that the cell is in a dormant state, and 0 indicates that the cell is in a non-dormant state, the terminal can determine that the first cell among the four first cells is in a dormant state, and the next three cells are in a non-dormant state; if 0 indicates that the cell is in a dormant state, and 1 indicates that the cell is in a non-dormant state, the terminal can determine that the first cell among the four first cells is in a non-dormant state, and the next three cells are in a dormant state.

[0217] In some embodiments, when the first information field of type-1a in MC-DCI is used to indicate the sleep state of the first cell, the terminal may determine the first scheduling information according to bits other than the first information field of type-1a in MC-DCI.

[0218] Accordingly, it can be ensured that when the first information field of type-1a indicates the sleep state of the first cell, the terminal can also determine the first scheduling information that can be indicated by the first information field of type-1a before refarming based on bits outside the first information field.

[0219] In some embodiments, the bits outside the first information field include at least one of the following:

[0220] New bits in downlink control information;

[0221] Bits in the other information field of the downlink control information.

[0222] In some embodiments, the other information fields include at least one of the following:

[0223] a second type of information field corresponding to a cell that is not scheduled among the multiple cells;

[0224] An information field containing reserved bits.

[0225] In some embodiments, the network device may add a new bit in the MC-DCI and indicate the first scheduling information of the first cell through the new bit, for example, by adding one or more bits after all bits of the MC-DCI. When the terminal determines the sleep state of the first cell based on the first information field in the MC-DCI, the terminal may determine the first scheduling information corresponding to the first information field based on the new bit in the MC-DCI.

[0226] For example, if MC-DCI originally occupies 80 bits and one bit is added to MC-DCI, the new MC-DCI occupies 81 bits. For example, if the first information field is the DMRS sequence initialization information field, the terminal can determine the sleep state of the first cell based on the DMRS sequence initialization information field in the MC-DCI and determine the DMRS sequence information based on the one bit added to the MC-DCI.

[0227] In some embodiments, the network device may indicate the first scheduling information of the first cell through a reserved bit in the MC-DCI.

[0228] In some embodiments, the network device may indicate the first scheduling information of the first cell through bits in other information fields in the MC-DCI.

[0229] For example, the network device can determine in the MC-DCI that there is an information field with reserved bits outside the type-1a information field, and then indicate the first scheduling information of the first cell through the reserved bits in the information field. The terminal can determine the first scheduling information of the first cell based on the reserved bits in the information field.

[0230] For example, the network device can determine the type-2 information field corresponding to the unscheduled cell in the MC-DCI. Since the cell corresponding to the type-2 information field is not scheduled, the type-2 information field may not be used to indicate the scheduling information of the corresponding cell. Therefore, the type-2 information field can be used to indicate the first scheduling information of the first cell. The terminal can determine the first scheduling information of the first cell based on the type-2 information field.

[0231] In some embodiments, the terminal may determine the sleep state of a reference cell in the at least one first cell according to the first information field.

[0232] In some embodiments, the terminal may also determine scheduling information of cells other than the reference cell according to the first information field.

[0233] For example, among the cells actually scheduled by MC-DCI, there are multiple first cells that meet the conditions for indicating cell dormancy based on information domain refarming. In this case, the terminal can determine the dormancy status of the reference cells in these first cells based only on the first information domain, that is, the first information domain only indicates the dormancy status for the reference cells in these first cells, and indicates scheduling information for cells other than the reference cells in these first cells.

[0234] In some embodiments, the reference cell includes at least one of the following: a cell with the largest identifier among the first cells; and a cell with the smallest identifier among the first cells.

[0235] For example, it is assumed that the at least one first cell includes three cells: cell#1, cell#3, and cell#4, and the first information field is a DMRS sequence initialization information field.

[0236] If the reference cell includes the cell with the largest identifier in the first cell, then the reference cell can be cell#4. The terminal can determine the sleep state of cell#4 based on the DMRS sequence initialization information field in the MC-DCI, and determine the DMRS sequence information of cell#1 and cell#3 based on the DMRS sequence initialization information field.

[0237] If the reference cell includes the cell with the largest identifier in the first cell, then the reference cell can be cell#1. The terminal can determine the sleep state of cell#1 based on the DMRS sequence initialization information field in the MC-DCI, and determine the DMRS sequence information of cell#3 and cell#4 based on the DMRS sequence initialization information field.
