Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0046] First, the relevant technologies and terms involved in the embodiments of the present application are briefly introduced.

[0047] 1. Multi-Cell Scheduling

[0048] In the multi-carrier scheduling work item, one downlink control information (DCI) is supported to schedule the physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) of multiple cells, and the DCI format (DCI format) is 0_X / 1_X (DCI format0_X / 1_X). One DCI can co-scheduled multiple scheduled cells. All scheduled cells and scheduling cells need to be in the same physical uplink control channel (PUCCH) group (PUCCH group).

[0049] For ease of understanding, the concepts of serving cell group, PUCCH group, set of cells, and cell combination are explained below:

[0050] Cell group: The concept with the largest scope among the above concepts refers to a group of cells configured by the network side (or network equipment) for the terminal, such as the Master Cell Group (MCG) and the Secondary Cell Group (SCG).

[0051] PUCCH group: The concept of PUCCH group is second only to the service cell group in scope among the above concepts. The cells included in a PUCCH group are a subset or a full set of all cells included in the service cell group. A service cell group may include 1 or 2 PUCCH groups. The Hybrid Automatic Repeat request-Acknowledgement (HARQ-ACK) codebook corresponding to the PDSCH on the cells within a PUCCH group is fed back on the cells within the same PUCCH group.

[0052] Cell set: The concept of the above concepts is second only to the PUCCH group in scope. It can be understood as a group of cells that can be scheduled by a DCI. In this group of cells, a cell combination that supports a DCI co-scheduled can be included. That is, a cell set can be understood as a group of cells consisting of all cells included in at least one of the above cell combinations. A PUCCH group may contain one or more cell sets.

[0053] In some embodiments of the present application, a cell and a carrier may be considered as equivalent concepts. One cell corresponds to one carrier, and one carrier corresponds to one cell. Multi-cell scheduling may also be understood as multi-carrier scheduling.

[0054] Cell combination or combination of co-scheduled Cells: A cell combination or combination of co-scheduled Cells includes N cells supporting one DCI co-scheduling, where N is a positive integer. The cell combination or combination of co-scheduled Cells can be understood as a subset or a full set of cell sets.

[0055] As an example, the relationship between the above concepts is illustrated as follows:

[0056] The terminal is configured with a primary service cell group, including Cell 1 to Cell 16 (Cell 1~Cell 16), a total of 16 cells, among which Cell 1 to Cell 8 (Cell 1~Cell 8) is a PUCCH group, recorded as PUCCH group 1, and Cell 9 to Cell 16 (Cell 9~Cell 16) is a PUCCH group, recorded as PUCCH group 2.

[0057] If the communication standard supports that a PUCCH group can contain multiple cell sets, then in PUCCH group 1, the network device can configure cells 1 to 4 {Cell 1~Cell 4} as the first cell set, and cells 5 to 8 {Cell5~Cell 8} as the second cell set. The cell combination is a subset or the whole set of the first cell set {Cell 1~Cell 4}, or the cell combination is a subset or the whole set of the second cell set {Cell 5~Cell 8}.

[0058] For example, in the first cell set, a cell combination or a co-scheduled cell combination that can be scheduled by a DCI is shown in the following Table 1. Table 1 contains a correspondence between a cell combination index and a co-scheduled cell combination or a cell combination.

[0059] Table 1: Combinations of cells that can be scheduled by a DCI in the first cell set

[0060]

[0061] 2. Cross-Carrier Scheduling

[0062] New Radio (NR) supports cross-carrier scheduling, that is, the scheduling cell and the scheduled cell are not the same cell, and the cross-carrier scheduling configuration information element (IE CrossCarrierSchedulingConfig) is used to configure the scheduling relationship of cross-carrier scheduling, that is, the above IE (Information Element) can configure the information of the scheduling cell corresponding to the scheduled cell, and the carrier indicator field (Carrier Indicator Field, CIF) value corresponding to the scheduled cell in the scheduling cell. CIF is the indication field in DCI used to indicate the scheduled cell. Since the candidate PDCCH (PDCCH candidate) (also called PDCCH resources) corresponding to different scheduled cells may overlap, the terminal can determine the scheduled cell according to CIF after detecting DCI in the candidate PDCCH.

[0063] ·CrossCarrierSchedulingConfig

[0064] The IE CrossCarrierSchedulingConfig is used to specify the configuration when the cross-carrier scheduling is used in a cell.

[0065] Cross-carrier scheduling configuration

[0066] The cross-carrier scheduling configuration information element is used to indicate the configuration when cross-carrier scheduling is used in a cell.

[0067] ·CrossCarrierSchedulingConfig information element

[0068]

[0069] ·cif-InSchedulingCell

[0070] The field indicates the CIF value used in the scheduling cell toindicate a grant or assignment applicable for this cell, see TS 38.213

[13] .

[0071] The carrier indicator field value of the scheduling cell

[0072] This field is used to indicate the CIF value used in the scheduling cell to indicate the grant or allocation applicable to the cell, see TS 38.213

[13] .

[0073] 3. Physical downlink control channel resources (PDCCH candidate) (also called candidate PDCCH)

[0074] The New Radio (NR) supports determining the physical resources of the PDCCH by configuring the Control Resource SET (CORESET) and the search space set. After determining the physical resources of the PDCCH, the terminal UE shall determine the set of candidate PDCCHs (PDCCHcandidate) contained in the physical resources of the PDCCH in the following manner:

[0075] In a PDCCH search space s, associated with CORESET p, the position of the candidate PDCCH is related to the CIF value, aggregation level, and the number of candidate PDCCHs, which can be determined by the following formula:

[0076]

[0077] in, Indicates the starting position of the candidate PPDCCH in the search space s, Indicates the address of the candidate PDCCH, n CI That is, the carrier indicator field CIF value mentioned above, L represents the aggregation level, N CCE,p Indicates the number of CCEs in CORESET p, Indicates the number of candidate PDCCHs corresponding to aggregation level L, Indicates rounding down.

[0078] It can be seen from the above formula that the n corresponding to different scheduled cells is CI Different, can be distinguished from the dimension of candidate PDCCH, but not necessarily completely distinguished, because the existence of formula modulus leads to different n CI The values ​​may correspond to the same candidate PDCCH.

[0079] At present, in the case of supporting one DCI to schedule multiple sets of cells, after a terminal performs blind detection on a PDCCH, it is not yet clear how to determine which cell combination (Cellcombination) in which cell set the blindly detected DCI schedules.

[0080] Based on this, an embodiment of the present application provides a scheduling method for a data channel and a scheme for DCI scheduling one or more cells. When supporting one DCI scheduling multiple cell sets, after the terminal performs a blind detection on the DCI, the terminal can accurately determine the cell set scheduled by the blindly detected DCI and the cell combination in the cell set.

[0081] For example, Figure 1 A schematic diagram of a communication system provided by an exemplary embodiment of the present application is shown. It mainly involves a terminal 120 and a network device 140. The network device 140 sends a first DCI, and the terminal 120 receives the first DCI. The first DCI is used to schedule N data channels, and the N data channels correspond to N cells in the first cell combination, where N is a positive integer.

[0084] The network device 140 and the terminal 120 communicate with each other via some air interface technology, such as a Uu interface.

[0085] In some embodiments, there are two communication scenarios between the network device 140 and the terminal 120: an uplink communication scenario and a downlink communication scenario.

[0088] Figure 2 FIG. 1 is a flowchart of a method for scheduling a data channel provided by an exemplary embodiment of the present application. Figure 1 The terminal 120 shown is executed as an example for explanation, including at least part of the following steps:

[0089] Step 200: Receive a first DCI, where the first DCI is used to schedule N data channels, where the N data channels correspond to N cells in a first cell combination, and N is a positive integer.

[0090] DCI is carried by PDCCH and is used to indicate the scheduling information of PDSCH or PUSCH of the terminal. The scheduling information includes at least one of time domain resource allocation, frequency domain resource allocation, modulation and coding scheme (MCS) format and other information.

[0091] In some embodiments, one DCI is supported to schedule PDSCH or PUSCH of one or more cells, that is, one DCI corresponds to one or more cells at the same time, and the one or more cells are called a cell combination. The cell combination can be a subset or a full set of a cell set, or a subset or a full set of PUCCH groups to which the cell set belongs.

[0092] For example, the serving cell group includes cell 1, cell 2, cell 3 and cell 4. In the case of supporting one DCI to schedule one or more cells at the same time, the cell combinations that can be scheduled by one DCI include but are not limited to the following: cell 1, cell 2, cell 3, cell 1+cell 2, cell 3+cell 4, cell 1+cell 2+cell 3, cell 2+cell 3+cell 4, cell 1+cell 2+cell 3+cell 4.

[0093] In some embodiments, the network device sends a first DCI to the terminal, where the first DCI is DCI received by the terminal and is used to schedule a first cell combination, where the first cell combination includes N cells, where N is a positive integer.

[0094] For example, the serving cell group includes cell 1, cell 2, cell 3 and cell 4. The terminal receives the first DCI, which is used to schedule the first cell combination. Assume that the first cell combination is cell 1+cell 2+cell 3, that is, the first cell combination includes 3 cells.

[0095] Optionally, the first DCI is used to schedule N data channels. The data channel includes a PDSCH or a PUSCH, the N data channels include N PDSCHs or N PUSCHs, the N data channels correspond one-to-one to the N cells in the first cell combination, and N is a positive integer.

[0096] For example, the serving cell group includes cell 1, cell 2, cell 3 and cell 4. The terminal receives the first DCI, assuming that the first cell combination is cell 1+cell 2+cell 3, then the first DCI is used to schedule three data channels, which are data channel A, data channel B and data channel C. Data channel A corresponds to cell 1 in the first cell combination, data channel B corresponds to cell 2, and data channel C corresponds to cell 3.

[0097] Optionally, the terminal performs blind detection on the PDCCH, and parses the first DCI obtained by the blind detection to determine N data channels scheduled by the first DCI, where the N data channels correspond to N cells in the first cell combination, where N is a positive integer.

[0098] In summary, in the method provided in the embodiment of the present application, the terminal receives the first DCI, the first DCI is used to schedule N data channels, the N data channels correspond to N cells in the first cell combination, and N is a positive integer. Using the method in the embodiment of the present application, a scheme for DCI scheduling one or more cells is provided, and the terminal can accurately determine the one or more cells scheduled by the DCI.

[0099] There are at least two possible implementations of step 200:

[0100] Method 1: The terminal first determines the first cell set corresponding to the first DCI, and then determines the first cell combination corresponding to the first DCI from the N cell combinations in the first cell set, where N is a positive integer.

[0101] In some embodiments, the first DCI carries a cell combination indication field, and the cell combination indication field is used to indicate the first cell combination.

[0102] In some embodiments, the cell combination indication field is used to indicate the first cell combination among P cell combinations corresponding to the first cell set, where P is a positive integer.

[0103] In some embodiments, the first DCI carries a cell set indication field, and the cell set indication field is used to indicate the first cell set in at least one cell set.

[0104] In some embodiments, the at least one cell set comprises at least two cell sets. In some embodiments, the at least two cell sets belong to the same PUCCH group.

[0105] In some embodiments, the first DCI carries a cell set indication field, and the cell set indication field is used to indicate the first cell set in at least two cell sets.

[0106] Mode 2: The terminal determines a first cell combination corresponding to the first DCI from among Q cell combinations corresponding to at least one cell set, where Q is a positive integer.

[0107] In some embodiments, the first DCI carries a cell combination indication field. The cell combination indication field is used to indicate a first cell combination among Q cell combinations corresponding to at least one cell set, where Q is a positive integer.

[0108] In some embodiments, the cell combination indication field is used to indicate a first cell combination among several cell combinations corresponding to a PUCCH group to which at least one cell set belongs.

[0109] In some embodiments, the at least one cell set comprises at least two cell sets. In some embodiments, the at least two cell sets belong to the same PUCCH group.

[0110] In some embodiments, the terminal determines a first cell combination corresponding to the first DCI from among Q cell combinations corresponding to at least two cell sets. Q is a positive integer.

[0111] In some embodiments, the first DCI carries a cell combination indication field. The cell combination indication field is used to indicate a first cell combination among Q cell combinations corresponding to at least two cell sets, where Q is a positive integer.

[0112] In some embodiments, the cell combination indication field is used to indicate a first cell combination among several cell combinations corresponding to the same PUCCH group where at least two cell sets are located.

[0113] In the above embodiment, when at least one cell set includes at least two cell sets, the network device sends the first DCI, which can save signaling resources.

[0114] For method one:

[0115] Figure 3 A flowchart of a data channel scheduling method provided by an exemplary embodiment of the present application is shown, wherein step 200 may optionally include the following steps 202 and 204:

[0116] Step 202: determine a first cell set corresponding to a first DCI.

[0117] In some embodiments, when one DCI is supported to schedule one or more cell sets, that is, when one DCI is supported to schedule at least one cell set, after receiving the first DCI, the terminal first determines the first cell set corresponding to the first DCI. The first cell set includes one or more cell combinations.

[0118] In some embodiments, the terminal receives high-level configuration information sent by the network device, and determines at least one cell set based on the high-level configuration information, or determines at least one cell set based on a method predefined in a protocol.

[0119] High-level configuration information refers to configuration information carried in the protocol layer above the physical layer, such as configuration information in signaling such as Radio Resource Control (RRC), System Information Block (SIB), and Medium Access Control (MAC). Protocol pre-defined refers to pre-defined by the communication protocol.

[0120] Each cell set in the at least one cell set is considered to be a group of cells that can be scheduled by the first DCI, or is referred to as a cell set consisting of at least one cell that can be jointly scheduled by the first DCI.

[0121] In some embodiments, the first set of cells is one of at least one set of cells.

[0122] In some embodiments, the first DCI carries a cell set indication field, and the cell set indication field is used to indicate the first cell set in at least one cell set.

[0123] In some embodiments, the number of bits of the cell set indicator field is determined according to the number of at least one cell set. The number of bits of the cell set indicator field refers to the number of bits occupied by the cell set indicator field.

[0124] In some embodiments, the number of bits of the cell set indication field is determined according to log2M; M is the number of at least one cell set corresponding to the terminal, and M is a positive integer.

[0125] In some embodiments, the number of bits in the cell set indication field is the result of rounding up log2M, that is, M is the number of cell sets in a PUCCH group to which at least one cell set belongs. M is a positive integer.

[0126] In some embodiments, at least one set of cells belongs to the same PUCCH group.

[0127] As an example, the serving cell group includes cell 1 to cell 16, a total of 16 cells. Among them, cell 1 to cell 8 are a PUCCH group, recorded as PUCCH group 1, and cell 9 to cell 16 are a PUCCH group, recorded as PUCCH group 2. In PUCCH group 1, the first cell set includes cell 1 to cell 4, and the second cell set includes cell 5 to cell 8. That is, the first cell set and the second cell set belong to the same PUCCH group, namely PUCCH group 1, and the terminal is in the cell combination corresponding to at least one cell set of PUCCH group 1, and then determines the first cell combination for the first DCI scheduling.

[0128] Step 204: determine a first cell combination for first DCI scheduling in the first cell set; wherein the first cell combination is a subset or the entire set of the first cell set.

[0129] In some embodiments, the first DCI carries a cell combination indication field, and the cell combination indication field is used to indicate the first cell combination among P cell combinations corresponding to the first cell set, where P is a positive integer.

[0130] In some embodiments, the number of bits of the cell combination indication field is determined according to the number P of cell combinations corresponding to the first cell set, where P is a positive integer.

[0131] In some embodiments, the number of bits of the cell combination indication field is determined according to log2P; P is the number of cell combinations corresponding to the first cell set, and P is a positive integer.

[0132] In some embodiments, the number of bits in the first cell combination indication field is the result of rounding up log2P, that is, P is the number of cell combinations corresponding to the first cell set, and P is a positive integer.

[0133] In some embodiments, the first DCI carries a cell combination indication field, and the cell combination indication field is used to indicate, in the P cell combinations corresponding to the first cell set, on the basis of indicating the first cell combination, such as Figure 4 and Figure 5 As shown, the method may further include step 230 or step 240:

[0134] Step 230, determining P cell combinations corresponding to the first cell set based on high-level configuration information; or,

[0135] Step 240, determining P cell combinations corresponding to the first cell set based on a method predefined in the protocol;

[0136] Wherein, P is a positive integer.

[0137] In some embodiments, the terminal receives high-level configuration information sent by the network device, and determines the P cell combinations corresponding to the first cell set based on the high-level configuration information, or determines the P cell combinations corresponding to the first cell set based on a protocol predefined method, where P is a positive integer.

[0138] As an example, the serving cell group includes cells 1 to 8, a total of 8 cells. Cells 1 to 8 are configured as 2 cell sets, namely a first cell set and a second cell set. The first cell set includes cells 1 to 4, and the second cell set includes cells 5 to 8.

[0139] The terminal receives a first DCI, and the first DCI includes a cell set indication field and a cell combination indication field. First, a first cell set corresponding to the first DCI is determined based on the cell set indication field, and the first cell set includes cells 1 to 4. Then, based on the cell combination indication field, a first cell combination scheduled by the first DCI is determined in at least one cell combination corresponding to the first cell set, for example, the first cell combination is cell 1+cell 2+cell 3. The first cell combination is a subset of the first cell set.

[0140] As an example, the terminal is configured with a primary service cell group, including cell 1 to cell 16, a total of 16 cells, where cell 1 to cell 8 are a PUCCH group, recorded as PUCCH group 1, and cell 9 to cell 16 are a PUCCH group, recorded as PUCCH group 2.

[0141] In PUCCH group 1, the network device configures a first cell set as Cell 1 to Cell 4 (Cell 1-Cell 4), and a second cell set as Cell 5 to Cell 8 (Cell 5-Cell 8).

[0142] The terminal receives the first DCI, which carries a cell set indication field. When the cell set is the first cell set and the second cell set, that is, the number of cell sets is 2, the number of bits in the cell set indication field is Bit.

[0143] Assume that the first cell set includes 4 cell combinations and the second cell set includes 8 cell combinations, and the number of each cell combination is unique in each cell set. For example, the first cell set includes cell combination 1 to cell combination 4, and the second cell set includes cell combination 1 to cell combination 8.

[0144] The number of bits of the cell combination indication field in the first DCI may be determined in one of the following ways:

[0145] The number of bits of the cell combination indication field corresponding to the first cell set is bits; the number of bits of the cell combination indication field corresponding to the second cell set is Bit.

[0146] The number of bits of the cell combination indication field corresponding to the first cell set and the second cell set are both Bit.

[0147] The method in the above embodiment is the most direct and simplest method. The terminal first determines the first cell set corresponding to the first DCI through the cell set indication field carried in the first DCI, and then determines the first cell combination in the first cell set scheduled by the first DCI through the cell combination indication field carried by the first DCI.

[0148] For method 2:

[0149] In another optional embodiment of the present application, Figure 6 A flowchart of a data channel scheduling method provided by an exemplary embodiment of the present application is shown. In step 200, determining a first cell combination for first DCI scheduling may include the following steps 250:

[0150] Step 250: Determine a first cell combination for first DCI scheduling among Q cell combinations corresponding to at least one cell set; Q is a positive integer.

[0151] In some embodiments, the first cell combination is a subset or a full set of a first cell set, and the first cell set is one of the at least one cell set.

[0152] In some embodiments, when the terminal is configured with one or more cell sets, that is, when supporting a DCI that can schedule a cell combination corresponding to at least one cell set, after receiving the first DCI, the terminal directly determines the first cell combination scheduled by the first DCI without first determining the first cell set.

[0153] In some embodiments, the terminal determines a first cell combination for the first DCI scheduling among Q cell combinations corresponding to at least one cell set, wherein the first cell combination is a subset of the first cell set, and the first cell set is one of the at least one cell set.

[0154] In some embodiments, the at least one cell set is a set of all cells configured for the terminal, or a set of all cells defined for the terminal, or the at least one cell set is one or more or all cell sets in the PUCCH group where the terminal is located.

[0155] In some embodiments, when the terminal determines the first cell combination scheduled by the first DCI in Q cell combinations corresponding to at least one cell set, as follows: Figure 7 and Figure 8 As shown, the method may also optionally include:

[0156] Step 260, determining Q cell combinations corresponding to at least one cell set based on high-level configuration information; or,

[0157] Step 270, determining Q cell combinations corresponding to at least one cell set based on a method predefined in the protocol;

[0158] Wherein, Q is a positive integer.

[0159] In some embodiments, the terminal and the network device agree on Q cell combinations corresponding to at least one cell set through high-level configuration information or in a protocol predefined manner, and the Q cell combinations corresponding to at least one cell set can be represented as a first cell combination table. Q is a positive integer.

[0160] In some embodiments, the terminal receives high-level configuration information sent by the network device, and determines Q cell combinations corresponding to at least one cell set based on the high-level configuration information, or determines Q cell combinations corresponding to at least one cell set based on a protocol predefined method. Q is a positive integer.

[0161] In some embodiments, the first cell combination table includes a cell combination index and a cell combination corresponding to the cell combination index.

[0162] In some embodiments, when the terminal determines the first cell combination scheduled by the first DCI in Q cell combinations corresponding to at least one cell set, as follows: Fig. 9 and Fig.10 As shown, the method may also optionally include:

[0163] Step 280, determining Q cell combinations corresponding to at least one cell set and a cell set corresponding to each cell combination based on high-level configuration information; or,

[0164] Step 290: Determine Q cell combinations corresponding to at least one cell set and a cell set corresponding to each cell combination based on a method predefined in the protocol; wherein Q is a positive integer.

[0165] In some embodiments, the terminal and the network device agree on a cell combination corresponding to at least one cell set and a cell set corresponding to each cell combination through high-level configuration information or in a protocol predefined manner. The cell set corresponding to each cell combination is represented by a cell set identifier (Set ID). The cell combination corresponding to at least one cell set and the cell set corresponding to each cell combination can be represented as a second cell combination table.

[0166] In some embodiments, the second cell combination table includes a cell combination index, a cell combination corresponding to the cell combination index, and a cell set identifier corresponding to the cell combination.

[0167] In some embodiments, the terminal receives high-level configuration information sent by the network device, and determines Q cell combinations corresponding to at least one cell set and the cell set corresponding to each cell combination based on the high-level configuration information; or, determines Q cell combinations corresponding to at least one cell set and the cell set corresponding to each cell combination based on a protocol predefined manner.

[0168] In some embodiments, the first DCI carries a cell combination indication field, and the cell combination indication field is used to indicate a first cell combination among Q cell combinations corresponding to at least one cell set. Q is a positive integer.

[0169] In some embodiments, the cell combination indication field is also used to indicate a first cell set corresponding to the first cell combination.

[0170] In some embodiments, the number of bits of the cell combination indication field is determined according to the number Q of cell combinations corresponding to at least one cell set.

[0171] In some embodiments, the number of bits of the cell combination indication field is determined according to log2Q; Q is the number of cell combinations corresponding to at least one cell set, and Q is a positive integer.

[0172] In some embodiments, the number of bits in the cell combination indication field is the result of rounding up log2Q, that is, Q is the number of cell combinations corresponding to at least one cell set, and Q is a positive integer.

[0173] In some embodiments, at least one set of cells belongs to the same PUCCH group.

[0174] As an example, the serving cell includes cell 1 to cell 16, a total of 16 cells. Among them, cell 1 to cell 8 are a PUCCH group, recorded as PUCCH group 1, and cell 9 to cell 16 are a PUCCH group, recorded as PUCCH group 2. In PUCCH group 1, the first cell set includes cell 1 to cell 4, and the second cell set includes cell 5 to cell 8. That is, the first cell set and the second cell set belong to the same PUCCH group, namely PUCCH group 1, and the terminal is in the cell combination corresponding to at least one cell set of PUCCH group 1, and then determines the first cell combination for the first DCI scheduling.

[0175] As an example, the terminal is configured with a primary service cell group, including cell 1 to cell 16, a total of 16 cells, where cell 1 to cell 8 are a PUCCH group, recorded as PUCCH group 1, and cell 9 to cell 16 are a PUCCH group, recorded as PUCCH group 2.

[0176] In PUCCH group 1, the network device configures the first cell set to be cells 1 to 4, and the second cell set to be cells 5 to 8.

[0177] Assuming that the first cell set contains 4 cell combinations and the second cell set contains 8 cell combinations, the cell combination indication field in the first DCI is Bit.

[0178] In some embodiments, the first DCI includes a cell combination indication field, and the cell combination indication field is used to indicate a first cell combination among Q cell combinations corresponding to at least one cell set. That is, the cell combination indication field indicates the first cell combination among 12 cell combinations corresponding to the first cell set and the second cell set.

[0179] In the above case, the first cell combination table includes a cell combination index and a cell combination corresponding to the cell combination index. The number of the cell combination index is irrelevant to the cell set. The first cell combination table is shown in Table 2 below.

[0180] In some embodiments, the first DCI includes a cell combination indication field, the cell combination indication field is used to indicate a first cell combination in Q cell combinations corresponding to at least one cell set, and the cell combination indication field is also used to indicate a first cell set corresponding to the first cell combination. That is, the cell combination indication field indicates the first cell combination and the first cell set corresponding to the first cell combination in 12 cell combinations corresponding to the first cell set and the second cell set.

[0181] In the above case, the second cell combination table includes a cell combination index, a cell combination corresponding to the cell combination index, and a cell set identifier corresponding to the cell combination. The second cell combination table is shown in Table 3. Among them, "0" in the cell set identifier represents the first cell set, and "1" represents the second cell set.

[0182] Table 2: First cell combination table

[0183]

[0184] Table 3: Second cell combination table

[0185]

[0186] In the above embodiment, the terminal directly determines the first cell combination scheduled by the first DCI without first determining the first cell set, which simplifies the behavior of the terminal UE to a certain extent.

[0187] In some embodiments, the relevant technical agreement stipulates that any cell in a cell set has the same corresponding scheduling cell. That is, the cells in the same cell set have the same corresponding scheduling cells. The scheduling cell refers to the cell where the terminal receives the DCI, or the cell corresponding to the carrier where the PDCCH carrying the DCI is located. That is, the terminal receives the DCI on the scheduling cell. The agreement is as follows:

[0188] ·Agreement

[0189] Confirm below working assumption reached in RAN1#110meeting with revision.

[0190] ·protocol

[0191] Confirm the following working assumptions reached at the relevant meetings and revise them.

[0192] Working Assumption

[0193] For any cell within a set of cells which can be co-scheduled by a DCIformat 0_X / 1_X,RAN1 specification supports monitoring the DCI format 0_X / 1_Xand DCI format 0_0 / 1_0,0_1 / 1_1,and / or 0_2 / 1_2(if supported by the UE),ifconfigured from a same scheduling cell.

[0194] Working hypothesis

[0195] For any cell within a group of cells that can be co-scheduled by DCI format 0_X / 1_X, the RAN1 specification supports monitoring of DCI format 0_X / 1uX and DCI formats 0 / 0 / 1_0, 0_1 / 1u1 and / or 0_2 / 1u2 (if supported by the terminal) if configured from the same scheduling cell.

[0196] In some embodiments, the at least one cell set includes at least two cell sets, and the scheduling cells corresponding to the cells in the same cell set are the same;

[0197] The cells in different cell sets correspond to different scheduling cells; or,

[0198] The scheduling cell corresponding to the cell in the cell set is one of the cells in the cell set.

[0199] In some embodiments, different cell sets correspond to different scheduling cells.

[0200] In some embodiments, the at least one cell set includes at least two cell sets, and the scheduling cells corresponding to the cells in the same cell set are the same;

[0201] The terminal does not expect that the scheduling cells corresponding to cells in different cell sets are the same.

[0202] In some embodiments, the terminal does not expect that the scheduling cell corresponding to the cell in the cell set is not one of the cells in the cell set.

[0203] In some embodiments, the terminal does not expect that the scheduled cells corresponding to different cell sets are the same.

[0204] In some embodiments, the network device sends the first DCI in a manner or an expected scheduling cell expected by the terminal. In some embodiments, when the network device does not send the first DCI in a manner or an expected scheduling cell expected by the terminal, this embodiment does not limit the subsequent processing method performed by the terminal. For example, the terminal can report an error, or process it through an error correction algorithm or a compatible algorithm.

[0205] As an example, the terminal is configured with a primary service cell group, including cell 1 to cell 16, a total of 16 cells, where cell 1 to cell 8 are a PUCCH group, recorded as PUCCH group 1, and cell 9 to cell 16 are a PUCCH group, recorded as PUCCH group 2.

[0206] In PUCCH group 1, the network device configures the first cell set to be cells 1 to 4, and the second cell set to be cells 5 to 8.

[0207] The network device configures the scheduling cell corresponding to all cells in the first cell set as cell x (Cell x), and the scheduling cell corresponding to all cells in the second cell set as cell y (Cell y). Cell x and Cell y are different cells, and there is no restriction that Cell x must be in the first cell set, nor is there any restriction that Cell y must be in the second cell set.

[0208] In the above embodiment, when the cells of different cell sets correspond to different scheduling cells, that is, the PDCCH resources corresponding to different cell sets are different, the terminal can determine the cell set corresponding to the detected DCI by detecting DCI on different PDCCH resources. The network device distinguishes the PDCCH resources corresponding to different cell sets by configuring restrictions (but the restrictions are small), which relatively saves DCI overhead. At the same time, the network device configures different scheduling cells for different cell sets, which can also relatively reduce the probability of PDCCH blocking configured on the same scheduling cell.

[0209] In some embodiments, when using Formula 1 to determine a candidate PDCCH (also called a PDCCH resource), Formula 1 is related to a search space set (search space set), a control resource set (Control Resource SET, CORESET), and a carrier indicator field value (ie, a carrier indicator field value CIF).

[0210] If some or all of the PDCCH resources corresponding to the first DCIs scheduling different cell sets are the same, when the terminal UE detects the first DCI in the PDCCH resources, it is impossible to determine the first cell set scheduled by the first DCI through the candidate PDCCH corresponding to the first DCI. Based on this:

[0211] In some embodiments, the at least one cell set comprises at least two cell sets;

[0212] The candidate PDCCHs corresponding to different cell sets are different; or,

[0213] Different cell sets correspond to different first configuration parameters; or,

[0214] The first configuration parameters corresponding to different cell sets are configured separately; or,

[0215] The first configuration parameters corresponding to different cell sets are configured independently; or,

[0216] The candidate PDCCHs determined based on the first configuration parameters corresponding to different cell sets are different; or,

[0217] The DCI sizes corresponding to different cell sets are the same;

[0218] The first configuration parameter is used to determine the candidate PDCCH.

[0219] In some embodiments, the at least one cell set comprises at least two cell sets;

[0220] The terminal does not expect that the candidate PDCCHs corresponding to different cell sets are the same; or,

[0221] The terminal does not expect that the first configuration parameters corresponding to different cell sets are the same; or,

[0222] The terminal does not expect that the first configuration parameters corresponding to different cell sets are uniformly configured; or,

[0223] The terminal does not expect that the first configuration parameters corresponding to different cell sets have the same configuration; or,

[0224] The terminal does not expect that the candidate PDCCHs determined based on the first configuration parameters corresponding to different cell sets are the same; or,

[0225] The terminal does not expect the DCI sizes corresponding to different cell sets to be the same;

[0226] The first configuration parameter is used to determine the candidate PDCCH.

[0227] In some embodiments, based on high-level configuration information sent by a network device, or based on a protocol predefined method, it is agreed that different candidate physical downlink control channels PDCCHs corresponding to different cell sets are different.

[0228] In some embodiments, the network device configures the first configuration parameters corresponding to different cell sets respectively, or configures the first configuration parameters corresponding to different cell sets independently, so that the terminal determines that the first configuration parameters corresponding to different cell sets are different.

[0229] In some embodiments, the DCI sizes corresponding to different cell sets are the same.

[0230] In some embodiments, the terminal determines different candidate PDCCHs according to first configuration parameters corresponding to different cell sets.

[0231] In some embodiments, the terminal does not expect that the candidate PDCCHs corresponding to different cell sets are the same.

[0232] In some embodiments, the terminal does not expect that the first configuration parameters corresponding to different cell sets are the same.

[0233] In some embodiments, the terminal does not expect the first configuration parameters corresponding to different cell sets to be uniformly configured, or the terminal does not expect the first configuration parameters corresponding to different cell sets to be identically configured.

[0234] In some embodiments, the terminal does not expect that the candidate PDCCHs determined based on the first configuration parameters corresponding to different cell sets are the same.

[0235] In some embodiments, the network device configures the first configuration parameter in a manner expected by the terminal. In some embodiments, when the network device does not configure the first configuration parameter in a manner expected by the terminal, this embodiment does not limit the subsequent processing method performed by the terminal. For example, the terminal may report an error, or perform processing through an error correction algorithm or a compatibility algorithm.

[0236] In some embodiments, the terminal does not expect that the DCI sizes corresponding to different cell sets are the same.

[0237] In some embodiments, the network device sends the DCI according to the DCI size expected by the terminal. In some embodiments, when the network device does not send the DCI according to the DCI size expected by the terminal, this embodiment does not limit the subsequent processing method performed by the terminal. For example, the terminal can report an error, or process it through an error correction algorithm or a compatible algorithm.

[0238] In some embodiments, the candidate PDCCHs are the same, which can be understood as all PDCCH resources overlapping.

[0239] In some embodiments, the first configuration parameter includes at least one of the following parameters:

[0240] Carrier indicator field value;

[0241] Search space set parameters;

[0242] Control resource set parameters.

[0243] As an example, the terminal is configured with a primary service cell group, including cell 1 to cell 16, a total of 16 cells, where cell 1 to cell 8 are a PUCCH group, recorded as PUCCH group 1, and cell 9 to cell 16 are a PUCCH group, recorded as PUCCH group 2.

[0244] In PUCCH group 1, the network device configures the first cell set to be cells 1 to 4, and the second cell set to be cells 5 to 8.

[0245] Assume that the first cell set and the second cell set correspond to the same search space set parameter and different carrier indicator field values ​​nCI. Wherein, nCI of the first cell set = 0 and nCI of the second cell set = 1. In formula 1, assuming that Y = 0, N = 32, L = 4, M = 4, then based on formula 1, it can be determined that: (see Fig.11 ) The PDCCH resources corresponding to the first cell set are the gray PDCCHs, and the PDCCH resources corresponding to the second cell set are the white PDCCHs. The white and gray PDCCH resources are different. Fig.11 The 0 to 31 in the table are CCE numbers.

[0246] In the above embodiment, the DCI corresponding to different cell sets is distinguished by the dimension of PDCCH resources, and there is no restriction that different cell sets correspond to the same scheduling cells. In order to save DCI overhead, the first configuration parameters corresponding to different cell sets are configured by the network device so that the PDCCH resources corresponding to different cell sets do not completely overlap, thereby distinguishing different cell sets. It should be noted that the above embodiment requires the network device to coordinate more parameter configurations, and the requirements for the implementation algorithm of the configuration of the network device are relatively high.

[0247] Fig.12 FIG. 1 is a flowchart of a method for scheduling a data channel provided by an exemplary embodiment of the present application. Figure 1 The network device 140 shown is used as an example to illustrate that the method includes at least a portion of the following steps:

[0248] Step 400: Send a first DCI, where the first DCI is used to schedule N data channels, where the N data channels correspond to N cells in a first cell combination, and N is a positive integer.

[0249] DCI is carried by PDCCH and is used to indicate the scheduling information of PDSCH or PUSCH of the terminal. The scheduling information includes at least one of time domain resource allocation, frequency domain resource allocation, modulation and coding scheme (MCS) format and other information.

[0250] In some embodiments, one DCI is supported to schedule PDSCH or PUSCH of one or more cells, that is, one DCI corresponds to one or more cells at the same time, and the one or more cells are called a cell combination. The cell combination can be a subset or a full set of a cell set, or a subset or a full set of PUCCH groups to which the cell set belongs.

[0251] For example, the serving cell group includes cell 1, cell 2, cell 3 and cell 4. In the case of supporting one DCI to schedule one or more cells at the same time, the cell combinations that can be scheduled by one DCI include but are not limited to the following: cell 1, cell 2, cell 3, cell 1+cell 2, cell 3+cell 4, cell 1+cell 2+cell 3, cell 2+cell 3+cell 4, cell 1+cell 2+cell 3+cell 4.

[0252] In some embodiments, the network device sends a first DCI to the terminal, where the first DCI is DCI received by the terminal and is used to schedule a first cell combination, where the first cell combination includes N cells, where N is a positive integer.

[0253] For example, the serving cell group includes cell 1, cell 2, cell 3 and cell 4. The terminal receives the first DCI, which is used to schedule the first cell combination. Assume that the first cell combination is cell 1+cell 2+cell 3, that is, the first cell combination includes 3 cells.

[0254] Optionally, the first DCI is used to schedule N data channels. The data channel includes a PDSCH or a PUSCH, the N data channels include N PDSCHs or N PUSCHs, the N data channels correspond one-to-one to the N cells in the first cell combination, and N is a positive integer.

[0255] For example, the serving cell group includes cell 1, cell 2, cell 3 and cell 4. The terminal receives the first DCI, assuming that the first cell combination is cell 1+cell 2+cell 3, then the first DCI is used to schedule three data channels, which are data channel A, data channel B and data channel C. Data channel A corresponds to cell 1 in the first cell combination, data channel B corresponds to cell 2, and data channel C corresponds to cell 3.

[0256] Optionally, the terminal performs blind detection on the PDCCH, and parses the first DCI obtained by the blind detection to determine N data channels scheduled by the first DCI, where the N data channels correspond to N cells in the first cell combination, where N is a positive integer.

[0257] In summary, the network device sends a first DCI to the terminal, the terminal receives the first DCI, the first DCI is used to schedule N data channels, the N data channels correspond to N cells in the first cell combination, and N is a positive integer. Using the method of the embodiment of the present application, a solution for DCI scheduling one or more cells is provided, and the terminal can accurately determine the one or more cells scheduled by the DCI.

[0258] In an optional implementation manner of the present application, in some embodiments, when one DCI is supported to schedule one or more cell sets, that is, when one DCI is supported to schedule at least one cell set, after receiving the first DCI, the terminal first determines the first cell set corresponding to the first DCI. The first cell set includes one or more cell combinations.

[0259] In some embodiments, the terminal receives high-level configuration information sent by the network device, and determines at least one cell set based on the high-level configuration information, or determines at least one cell set based on a method predefined in a protocol.

[0260] High-level configuration information refers to configuration information carried in the protocol layer above the physical layer, such as configuration information in signaling such as Radio Resource Control (RRC), System Information Block (SIB), and Medium Access Control (MAC). Protocol pre-defined refers to pre-defined by the communication protocol.

[0261] Each cell set in the at least one cell set is considered to be a group of cells that can be scheduled by the first DCI, or is referred to as a cell set consisting of at least one cell that can be jointly scheduled by the first DCI.

[0262] In some embodiments, the first set of cells is one of at least one set of cells.

[0263] In some embodiments, the first DCI carries a cell set indication field, and the cell set indication field is used to indicate the first cell set in at least one cell set.

[0264] In some embodiments, the number of bits of the cell set indicator field is determined according to the number of at least one cell set. The number of bits of the cell set indicator field refers to the number of bits occupied by the cell set indicator field.

[0265] In some embodiments, the number of bits of the cell set indication field is determined according to log2M; M is the number of at least one cell set corresponding to the terminal, and M is a positive integer.

[0266] In some embodiments, the number of bits in the cell set indication field is the result of rounding up log2M, that is, M is the number of cell sets in a PUCCH group to which at least one cell set belongs. M is a positive integer.

[0267] In some embodiments, at least one set of cells belongs to the same PUCCH group.

[0268] As an example, the serving cell group includes cell 1 to cell 16, a total of 16 cells. Among them, cell 1 to cell 8 are a PUCCH group, recorded as PUCCH group 1, and cell 9 to cell 16 are a PUCCH group, recorded as PUCCH group 2. In PUCCH group 1, the first cell set includes cell 1 to cell 4, and the second cell set includes cell 5 to cell 8. That is, the first cell set and the second cell set belong to the same PUCCH group, namely PUCCH group 1, and the terminal is in the cell combination corresponding to at least one cell set of PUCCH group 1, and then determines the first cell combination for the first DCI scheduling.

[0269] In some embodiments, the first DCI carries a cell combination indication field, and the cell combination indication field is used to indicate the first cell combination among P cell combinations corresponding to the first cell set, where P is a positive integer.

[0270] In some embodiments, the number of bits of the cell combination indication field is determined according to the number P of cell combinations corresponding to the first cell set, where P is a positive integer.

[0271] In some embodiments, the number of bits of the cell combination indication field is determined according to log2P; P is the number of cell combinations corresponding to the first cell set, and P is a positive integer.

[0272] In some embodiments, the number of bits in the first cell combination indication field is the result of rounding up log2P, that is, P is the number of cell combinations corresponding to the first cell set, and P is a positive integer.

[0273] In some embodiments, the first DCI carries a cell combination indication field, and the cell combination indication field is used to indicate, in the P cell combinations corresponding to the first cell set, on the basis of indicating the first cell combination, such as Fig.13 and Fig.14 As shown, the method may also include:

[0274] Step 430: indicating P cell combinations corresponding to the first cell set based on high-level configuration information; or,

[0275] Step 440, indicating P cell combinations corresponding to the first cell set based on a protocol predefined method;

[0276] Wherein, P is a positive integer.

[0277] In some embodiments, the network device sends high-level configuration information, the terminal receives the high-level configuration information sent by the network device, and determines the P cell combinations corresponding to the first cell set based on the high-level configuration information, or determines the P cell combinations corresponding to the first cell set based on a method predefined by the protocol, where P is a positive integer.

[0278] As an example, the serving cell group includes cells 1 to 8, a total of 8 cells. Cells 1 to 8 are configured as 2 cell sets, namely a first cell set and a second cell set. The first cell set includes cells 1 to 4, and the second cell set includes cells 5 to 8.

[0279] The terminal receives a first DCI, and the first DCI includes a cell set indication field and a cell combination indication field. First, a first cell set corresponding to the first DCI is determined based on the cell set indication field, and the first cell set includes cells 1 to 4. Then, based on the cell combination indication field, a first cell combination scheduled by the first DCI is determined in at least one cell combination corresponding to the first cell set, for example, the first cell combination is cell 1+cell 2+cell 3. The first cell combination is a subset of the first cell set.

[0280] As an example, the terminal is configured with a primary service cell group, including cell 1 to cell 16, a total of 16 cells, where cell 1 to cell 8 are a PUCCH group, recorded as PUCCH group 1, and cell 9 to cell 16 are a PUCCH group, recorded as PUCCH group 2.

[0281] In PUCCH group 1, the network device configures a first cell set as Cell 1 to Cell 4 (Cell 1-Cell 4), and a second cell set as Cell 5 to Cell 8 (Cell 5-Cell 8).

[0282] The terminal receives the first DCI, which carries a cell set indication field. When the cell set is the first cell set and the second cell set, that is, the number of cell sets is 2, the number of bits in the cell set indication field is Bit.

[0283] Assume that the first cell set includes 4 cell combinations and the second cell set includes 8 cell combinations, and the number of each cell combination is unique in each cell set. For example, the first cell set includes cell combination 1 to cell combination 4, and the second cell set includes cell combination 1 to cell combination 8.

[0284] The number of bits of the cell combination indication field in the first DCI may be determined in one of the following ways:

[0285] The number of bits of the cell combination indication field corresponding to the first cell set is bits; the number of bits of the cell combination indication field corresponding to the second cell set is Bit.

[0286] The number of bits of the cell combination indication field corresponding to the first cell set and the second cell set are both Bit.

[0287] The method in the above embodiment is the most direct and simplest method. The network device sends the first DCI, and the terminal first determines the first cell set corresponding to the first DCI through the cell set indication field carried in the first DCI, and then determines the first cell combination in the first cell set scheduled by the first DCI through the cell combination indication field carried by the first DCI.

[0288] In another optional implementation manner of the present application, the terminal determines a first cell combination for the first DCI scheduling among Q cell combinations corresponding to at least one cell set; Q is a positive integer.

[0289] In some embodiments, the first cell combination is a subset or a full set of a first cell set, and the first cell set is one of the at least one cell set.

[0290] In some embodiments, when the terminal is configured with one or more cell sets, that is, when supporting a DCI that can schedule a cell combination corresponding to at least one cell set, after receiving the first DCI, the terminal directly determines the first cell combination scheduled by the first DCI without first determining the first cell set.

[0291] In some embodiments, the terminal determines a first cell combination for the first DCI scheduling among Q cell combinations corresponding to at least one cell set, wherein the first cell combination is a subset of the first cell set, and the first cell set is one of the at least one cell set.

[0292] In some embodiments, the at least one cell set is a set of all cells configured for the terminal, or a set of all cells defined for the terminal, or the at least one cell set is one or more or all cell sets in the PUCCH group where the terminal is located.

[0293] In some embodiments, when the terminal determines the first cell combination scheduled by the first DCI in Q cell combinations corresponding to at least one cell set, as follows: Fig.15 and Fig.16 As shown, the method may also optionally include:

[0294] Step 460: indicating Q cell combinations corresponding to at least one cell set based on high-level configuration information; or,

[0295] Step 470, indicating Q cell combinations corresponding to at least one cell set based on a protocol predefined method;

[0296] Wherein, Q is a positive integer.

[0297] In some embodiments, the terminal and the network device agree on Q cell combinations corresponding to at least one cell set through high-level configuration information or in a protocol predefined manner, and the Q cell combinations corresponding to at least one cell set can be represented as a first cell combination table. Q is a positive integer.

[0298] In some embodiments, the terminal receives high-level configuration information sent by the network device, and determines Q cell combinations corresponding to at least one cell set based on the high-level configuration information, or determines Q cell combinations corresponding to at least one cell set based on a protocol predefined method. Q is a positive integer.

[0299] In some embodiments, the first cell combination table includes a cell combination index and a cell combination corresponding to the cell combination index.

[0300] In some embodiments, when the terminal determines the first cell combination scheduled by the first DCI in Q cell combinations corresponding to at least one cell set, as follows: Fig.17 and Fig.18 As shown, the method may also optionally include:

[0301] Step 480: indicating, based on high-level configuration information, Q cell combinations corresponding to at least one cell set and a cell set corresponding to each cell combination; or,

[0302] Step 490, indicating Q cell combinations corresponding to at least one cell set and a cell set corresponding to each cell combination in a manner predefined by the protocol;

[0303] Wherein, Q is a positive integer.

[0304] In some embodiments, the terminal and the network device agree on a cell combination corresponding to at least one cell set and a cell set corresponding to each cell combination through high-level configuration information or in a protocol predefined manner. The cell set corresponding to each cell combination is represented by a cell set identifier (Set ID). The cell combination corresponding to at least one cell set and the cell set corresponding to each cell combination can be represented as a second cell combination table.

[0305] In some embodiments, the second cell combination table includes a cell combination index, a cell combination corresponding to the cell combination index, and a cell set identifier corresponding to the cell combination.

[0306] In some embodiments, the terminal receives high-level configuration information sent by the network device, and determines Q cell combinations corresponding to at least one cell set and the cell set corresponding to each cell combination based on the high-level configuration information; or, determines Q cell combinations corresponding to at least one cell set and the cell set corresponding to each cell combination based on a protocol predefined manner.

[0307] In some embodiments, the first DCI carries a cell combination indication field, and the cell combination indication field is used to indicate a first cell combination among Q cell combinations corresponding to at least one cell set. Q is a positive integer.

[0308] In some embodiments, the cell combination indication field is also used to indicate a first cell set corresponding to the first cell combination.

[0309] In some embodiments, the number of bits of the cell combination indication field is determined according to the number Q of cell combinations corresponding to at least one cell set.

[0310] In some embodiments, the number of bits of the cell combination indication field is determined according to log2Q; Q is the number of cell combinations corresponding to at least one cell set, and Q is a positive integer.

[0311] In some embodiments, the number of bits in the cell combination indication field is the result of rounding up log2Q, that is, Q is the number of cell combinations corresponding to at least one cell set, and Q is a positive integer.

[0312] In some embodiments, at least one set of cells belongs to the same PUCCH group.

[0313] As an example, the serving cell includes cell 1 to cell 16, a total of 16 cells. Among them, cell 1 to cell 8 are a PUCCH group, recorded as PUCCH group 1, and cell 9 to cell 16 are a PUCCH group, recorded as PUCCH group 2. In PUCCH group 1, the first cell set includes cell 1 to cell 4, and the second cell set includes cell 5 to cell 8. That is, the first cell set and the second cell set belong to the same PUCCH group, namely PUCCH group 1, and the terminal is in the cell combination corresponding to at least one cell set of PUCCH group 1, and then determines the first cell combination for the first DCI scheduling.

[0314] As an example, the terminal is configured with a primary service cell group, including cell 1 to cell 16, a total of 16 cells, where cell 1 to cell 8 are a PUCCH group, recorded as PUCCH group 1, and cell 9 to cell 16 are a PUCCH group, recorded as PUCCH group 2.

[0315] In PUCCH group 1, the network device configures the first cell set to be cells 1 to 4, and the second cell set to be cells 5 to 8.

[0316] Assuming that the first cell set contains 4 cell combinations and the second cell set contains 8 cell combinations, the cell combination indication field in the first DCI is Bit.

[0317] In some embodiments, the first DCI includes a cell combination indication field, and the cell combination indication field is used to indicate a first cell combination among Q cell combinations corresponding to at least one cell set. That is, the cell combination indication field indicates the first cell combination among 12 cell combinations corresponding to the first cell set and the second cell set.

[0318] In the above case, the first cell combination table includes a cell combination index and a cell combination corresponding to the cell combination index. The number of the cell combination index is irrelevant to the cell set. The first cell combination table is shown in Table 4 below.

[0319] In some embodiments, the first DCI includes a cell combination indication field, the cell combination indication field is used to indicate a first cell combination in Q cell combinations corresponding to at least one cell set, and the cell combination indication field is also used to indicate a first cell set corresponding to the first cell combination. That is, the cell combination indication field indicates the first cell combination and the first cell set corresponding to the first cell combination in 12 cell combinations corresponding to the first cell set and the second cell set.

[0320] In the above case, the second cell combination table includes a cell combination index, a cell combination corresponding to the cell combination index, and a cell set identifier corresponding to the cell combination. The second cell combination table is shown in Table 5. Among them, "0" in the cell set identifier represents the first cell set, and "1" represents the second cell set.

[0321] Table 4: First cell combination table

[0322]

[0323]

[0324] Table 5: Second cell combination table

[0325]

[0326] In the above embodiment, the network device directly indicates the first cell combination through the first DCI, and the terminal directly determines the first cell combination scheduled by the first DCI without first determining the first cell set, which simplifies the behavior of the terminal UE to a certain extent.

[0327] In some embodiments, the relevant technical agreement stipulates that any cell in a cell set has the same corresponding scheduling cell. That is, the cells in the same cell set have the same corresponding scheduling cells. The scheduling cell refers to the cell where the terminal receives the DCI, or the cell corresponding to the carrier where the PDCCH carrying the DCI is located. That is, the terminal receives the DCI on the scheduling cell. The agreement is as follows:

[0328] ·Agreement

[0329] Confirm below working assumption reached in RAN1#110meeting with revision.

[0330] ·protocol

[0331] Confirm the following working assumptions reached at the relevant meetings and revise them.

[0332] Working Assumption

[0333] For any cell within a set of cells which can be co-scheduled by a DCIformat 0_X / 1_X,RAN1 specification supports monitoring the DCI format 0_X / 1_Xand DCI format 0_0 / 1_0,0_1 / 1_1,and / or 0_2 / 1_2(if supported by the UE),ifconfigured from a same scheduling cell.

[0334] Working hypothesis

[0335] For any cell within a group of cells that can be co-scheduled by DCI format 0_X / 1_X, the RAN1 specification supports monitoring of DCI format 0_X / 1uX and DCI formats 0 / 0 / 1_0, 0_1 / 1u1 and / or 0_2 / 1u2 (if supported by the terminal) if configured from the same scheduling cell.

[0336] In some embodiments, the at least one cell set includes at least two cell sets, and the scheduling cells corresponding to the cells in the same cell set are the same;

[0337] The cells in different cell sets correspond to different scheduling cells; or,

[0338] The scheduling cell corresponding to the cell in the cell set is one of the cells in the cell set.

[0339] In some embodiments, different cell sets correspond to different scheduling cells.

[0340] In some embodiments, the at least one cell set includes at least two cell sets, and the scheduling cells corresponding to the cells in the same cell set are the same;

[0341] The terminal does not expect that the scheduling cells corresponding to cells in different cell sets are the same.

[0342] In some embodiments, the terminal does not expect that the scheduling cell corresponding to the cell in the cell set is not one of the cells in the cell set.

[0343] In some embodiments, the terminal does not expect that the scheduled cells corresponding to different cell sets are the same.

[0344] In some embodiments, the network device sends the first DCI in a manner or an expected scheduling cell expected by the terminal. In some embodiments, when the network device does not send the first DCI in a manner or an expected scheduling cell expected by the terminal, this embodiment does not limit the subsequent processing method performed by the terminal. For example, the terminal can report an error, or process it through an error correction algorithm or a compatible algorithm.

[0345] As an example, the terminal is configured with a primary service cell group, including cell 1 to cell 16, a total of 16 cells, where cell 1 to cell 8 are a PUCCH group, recorded as PUCCH group 1, and cell 9 to cell 16 are a PUCCH group, recorded as PUCCH group 2.

[0346] In PUCCH group 1, the network device configures the first cell set to be cells 1 to 4, and the second cell set to be cells 5 to 8.

[0347] The network device configures the scheduling cell corresponding to all cells in the first cell set as cell x (Cell x), and the scheduling cell corresponding to all cells in the second cell set as cell y (Cell y). Cell x and Cell y are different cells, and there is no restriction that Cell x must be in the first cell set, nor is there any restriction that Cell y must be in the second cell set.

[0348] In the above embodiment, when the cells of different cell sets correspond to different scheduling cells, that is, the PDCCH resources corresponding to different cell sets are different, the terminal can determine the cell set corresponding to the detected DCI by detecting DCI on different PDCCH resources. The network device distinguishes the PDCCH resources corresponding to different cell sets by configuring restrictions (but the restrictions are small), which relatively saves DCI overhead. At the same time, the network device configures different scheduling cells for different cell sets, which can also relatively reduce the probability of PDCCH blocking configured on the same scheduling cell.

[0349] In some embodiments, when the terminal uses Formula 1 to determine a candidate PDCCH (also called a PDCCH resource), Formula 1 is related to a search space set (search space set), a control resource set (Control Resource SET, CORESET), and a carrier indicator field value (ie, a carrier indicator field value CIF).

[0350] If some or all of the PDCCH resources corresponding to the first DCIs scheduling different cell sets are the same, when the terminal UE detects the first DCI in the PDCCH resources, it is impossible to determine the first cell set scheduled by the first DCI through the candidate PDCCH corresponding to the first DCI. Based on this:

[0351] In some embodiments, the at least one cell set comprises at least two cell sets;

[0352] The candidate PDCCHs corresponding to different cell sets are different; or,

[0353] Different cell sets correspond to different first configuration parameters; or,

[0354] The first configuration parameters corresponding to different cell sets are configured separately; or,

[0355] The first configuration parameters corresponding to different cell sets are configured independently; or,

[0356] The candidate PDCCHs determined based on the first configuration parameters corresponding to different cell sets are different; or,

[0357] The DCI sizes corresponding to different cell sets are the same;

[0358] The first configuration parameter is used to determine the candidate PDCCH.

[0359] In some embodiments, the at least one cell set comprises at least two cell sets;

[0360] The terminal does not expect that the candidate PDCCHs corresponding to different cell sets are the same; or,

[0361] The terminal does not expect that the first configuration parameters corresponding to different cell sets are the same; or,

[0362] The terminal does not expect that the first configuration parameters corresponding to different cell sets are uniformly configured; or,

[0363] The terminal does not expect that the first configuration parameters corresponding to different cell sets have the same configuration; or,

[0364] The terminal does not expect that the candidate PDCCHs determined based on the first configuration parameters corresponding to different cell sets are the same; or,

[0365] The terminal does not expect the DCI sizes corresponding to different cell sets to be the same;

[0366] The first configuration parameter is used to determine the candidate PDCCH.

[0367] In some embodiments, based on high-level configuration information sent by a network device, or based on a protocol predefined method, it is agreed that different candidate physical downlink control channels PDCCHs corresponding to different cell sets are different.

[0368] In some embodiments, the network device configures the first configuration parameters corresponding to different cell sets respectively, or configures the first configuration parameters corresponding to different cell sets independently, so that the terminal determines that the first configuration parameters corresponding to different cell sets are different.

[0369] In some embodiments, the DCI sizes corresponding to different cell sets are the same.

[0370] In some embodiments, the terminal determines different candidate PDCCHs according to first configuration parameters corresponding to different cell sets.

[0371] In some embodiments, the terminal does not expect that the candidate PDCCHs corresponding to different cell sets are the same.

[0372] In some embodiments, the terminal does not expect that the first configuration parameters corresponding to different cell sets are the same.

[0373] In some embodiments, the terminal does not expect the first configuration parameters corresponding to different cell sets to be uniformly configured, or the terminal does not expect the first configuration parameters corresponding to different cell sets to be identically configured.

[0374] In some embodiments, the terminal does not expect that the candidate PDCCHs determined based on the first configuration parameters corresponding to different cell sets are the same.

[0375] In some embodiments, the network device configures the first configuration parameter in a manner expected by the terminal. In some embodiments, when the network device does not configure the first configuration parameter in a manner expected by the terminal, this embodiment does not limit the subsequent processing method performed by the terminal. For example, the terminal may report an error, or perform processing through an error correction algorithm or a compatibility algorithm.

[0376] In some embodiments, the terminal does not expect that the DCI sizes corresponding to different cell sets are the same.

[0377] In some embodiments, the network device sends the DCI according to the DCI size expected by the terminal. In some embodiments, when the network device does not send the DCI according to the DCI size expected by the terminal, this embodiment does not limit the subsequent processing method performed by the terminal. For example, the terminal can report an error, or process it through an error correction algorithm or a compatible algorithm.

[0378] In some embodiments, the candidate PDCCHs are the same, which can be understood as all PDCCH resources overlapping.

[0379] In some embodiments, the first configuration parameter includes at least one of the following parameters:

[0380] Carrier indicator field value;

[0381] Search space set parameters;

[0382] Control resource set parameters.

[0383] As an example, the terminal is configured with a primary service cell group, including cell 1 to cell 16, a total of 16 cells, where cell 1 to cell 8 are a PUCCH group, recorded as PUCCH group 1, and cell 9 to cell 16 are a PUCCH group, recorded as PUCCH group 2.

[0384] In PUCCH group 1, the network device configures the first cell set to be cells 1 to 4, and the second cell set to be cells 5 to 8.

[0385] Assume that the first cell set and the second cell set correspond to the same search space set parameter and different carrier indicator field values ​​nCI. Wherein, nCI of the first cell set = 0 and nCI of the second cell set = 1. In formula 1, assuming that Y = 0, N = 32, L = 4, M = 4, then based on formula 1, it can be determined that: (see Fig.11 ) The PDCCH resources corresponding to the first cell set are the gray PDCCHs, and the PDCCH resources corresponding to the second cell set are the white PDCCHs. The white and gray PDCCH resources are different. Fig.11 The 0 to 31 in the table are CCE numbers.

[0386] In the above embodiment, the DCI corresponding to different cell sets is distinguished by the dimension of PDCCH resources, and there is no restriction that different cell sets correspond to the same scheduling cells. In order to save DCI overhead, the first configuration parameters corresponding to different cell sets are configured by the network device so that the PDCCH resources corresponding to different cell sets do not completely overlap, thereby distinguishing different cell sets. It should be noted that the above embodiment requires the network device to coordinate more parameter configurations, and the requirements for the implementation algorithm of the configuration of the network device are relatively high.
