[0028] First, the related technologies involved in the embodiments of the present application are introduced:

[0029] (1) Time Domain Resource Assignment / Allocation (TDRA) for PDSCH / PUSCH

[0030] In the related art, a downlink control information (Downlink Control Information, DCI) is supported to schedule a PDSCH or PUSCH. The DCI includes a time domain resource allocation field (TDRA field) for indicating the time domain resource allocation of the PDSCH or PUSCH scheduled by the DCI (including the time slot where the PDSCH / PUSCH is located, the occupied symbols, the mapping type, etc.); the specific determination method of the time domain resource allocation of the PDSCH / PUSCH is as follows:

[0031] 1) A TDRA table is configured for the terminal device through a Radio Resource Control (RRC) parameter (e.g., pdsch-TimeDomainAllocationList / pusch-TimeDomainAllocationList); or, one or more TDRA lists are agreed upon for the terminal device through a protocol agreement; the TDRA list includes one TDRA element or multiple TDRA elements, each of which includes the following parameters:

[0032] Slot offset K0 / K2, used to determine the slot offset between the DCI slot and the PDSCH / PUSCH slot;

[0033] The start and length indicator, SLIV, or simply start symbol (S) and allocation length (L), is used to determine the start symbol and number of symbols occupied by PDSCH / PUSCH;

[0034] PDSCH / PUSCH mapping type, used to determine the mapping type of PDSCH / PUSCH;

[0035] 2) Through the TDRA field included in the DCI, a TDRA element is indicated from the TDRA list configured by RRC or the TDRA list agreed upon by the protocol: for example, the TDRA field indication value m provides a row index m+1 to the above allocation table.

[0036] The relevant signaling for configuring the TDRA list through RRC parameters (such as pdsch-TimeDomainAllocationList / pusch-TimeDomainAllocationList) is as follows:

[0037] PDSCH-TimeDomainResourceAllocationList

[0038] The PDSCH-TimeDomainResourceAllocation information element is used to configure the time domain resource allocation information of PDSCH, including the time slot, symbol, mapping type, etc. occupied by PDSCH. The PDSCH-TimeDomainResourceAllocationList contains one or more such PDSCH-TimeDomainResourceAllocations. The network device indicates in the downlink configuration which time domain resource allocation information element of the time domain resource allocation list the PDSCH scheduled by the terminal device corresponds to. The terminal device determines the bit width of the DCI domain based on the number of entries in the PDSCH-TimeDomainResourceAllocationList. The value 0 in the DCI domain represents the first element in this table, the value 1 in the DCI domain represents the second element in this table, and so on.

[0039] The IE PDSCH-TimeDomainResourceAllocation is used to configure the TDRA of PDSCH, including at least slot, symbols, mapping type occupied by the PDSCH. The PDSCH-TimeDomainResourceAllocationList contains one or more of such PDSCH-TimeDomainResourceAllocations. The network indicates in the DL assignment which of the configured time domain allocations the UE shall apply for that DL assignment. The UE determines the bit width of the DCI field based on the number of entries in the PDSCH-TimeDomainResourceAllocationList. Value 0 in the DCI field refers to the first element in this list, value 1 in the DCI field refers to the second element in this list, and so on.

[0048] (2) Single Cell Multi-PDSCH / PUSCH scheduling

[0049] In the work item "Extending current NR operation to 71GHz", in order to support larger subcarrier spacing, the physical downlink control channel (PDCCH) blind detection period is added, and the feature of scheduling multiple PDSCHs or PUSCHs in the same cell by one DCI is supported. Each of the multiple PDSCHs / PUSCHs is used to carry different transport blocks (TB). Some indication fields in the DCI are shared by all PDSCHs, and some indication fields are indicated for each (per) PDSCH / PUSCH. For time domain resource allocation, the function of multiple PUSCHs (multi-PUSCH) in the new radio in unlicensed spectrum (NR-U) working in unlicensed / licensed frequency bands / spectrums is reused. Among them, the TDRA list is extended, and each TDRA element can indicate the SLIV, PDSCH / PUSCH mapping type, and slot offset K0 / K2 of one or more PDSCH / PUSCHs. The configuration signaling is as follows:

[0062] }

[0063] (3) Multi-Cell Scheduling

[0064] In the "Multi-Carrier" work item, the feature of supporting one DCI to schedule multiple PDSCH / PUSCH of multiple cells is supported. Multiple scheduled cells scheduled by one DCI are indicated by the DCI. The specific indication method needs to be further studied in the following options, among which option 1 is the majority view:

[0065] Agreement:

[0066] For multi-cell scheduling, the co-scheduled cells are indicated by DCI format 0_X / 1_X. At least the following options are considered:

[0067] Option 1: The indicator in the DCI points to a table defining the scheduled cell combination, such as a TDRA element in the TDRA list.

[0068] The table is configured by RRC signaling.

[0069] Option 2: One indicator in the DCI is a bitmap corresponding to a set of configured cells that can be scheduled by DCI 0_X / 1_X.

[0070] Option 3: Use existing fields, such as Carrier Indicator Field (CIF) and Frequency Domain Resource Allocation (FDRA), to indicate whether one or more cells are scheduled.

[0071] Other options are not excluded.

[0072] For multi-cell scheduling, the co-scheduled cells are indicated by DCIformat 0_X / 1_X.At least the following options are considered:

[0073] ·Option 1:An indicator in the DCI points to one row of atabledefining combinations of scheduled cells.

[0074] The table is configured by RRC signaling.

[0075] ·Option 2:An indicator in the DCI is a bitmap corresponding to a setof configured cells that can be scheduled by the DCI 0_X / 1_X.

[0076] ·Option 3:using existing field(eg,CIF,FDRA)to indicate whether one or more cells are scheduled or not.

[0077] ·Other options are not precluded.

[0078] At the same time, DCI format 0_X is used to schedule multiple PUSCHs on multiple cells, and DCI format 1_X is used to schedule multiple PDSCHs on multiple cells; in addition, all scheduled cells and scheduling cells scheduled by DCI format 1_X are included in the same physical uplink control channel (Physical Uplink Control CHannel, PUCCH) group, and all scheduled cells and scheduling cells scheduled by DCI format 0_X are in the same cell group or PUCCH group.

[0079] (4) Cell Group and PUCCH Group

[0080] When the terminal device works in dual connectivity (DC) / carrier aggregation (CA) mode, a master cell group (MCG) and a secondary cell group (SCG) can be configured for the terminal device through the network device:

[0081] MCG: A group of serving cells, including a master node, whose special cell is the primary cell (PCell).

[0082] SCG: A group of serving cells, including a secondary node (Secondary Node), whose special cell is the primary secondary cell (PSCell).

[0083] In some embodiments, the terminal device cannot feedback PUCCH on all service cells in the MCG and SCG. Assuming that the network device expects to configure at least two service cells in the cell group (MCG or SCG) as the same PUCCH group, the network device can configure the "PUCCH cell (pucch-Cell)" parameter for some or all of the at least two service cells so that the at least two service cells are classified into the same PUCCH group; and then implicitly divide the cell group (MCG or SCG) into two PUCCH groups, wherein the hybrid automatic repeat request-acknowledgement (Hybrid Automatic Repeat Request-Acknowledge, HARQ-ACK) information corresponding to the PDSCH on the cells in one PUCCH group is fed back on the special cell of the cell group, and the HARQ-ACK information corresponding to the PDSCH on the cells in the other PUCCH group is fed back on the configured PUCCH secondary cell (PUCCH SCell).

[0084] The at least two serving cells (corresponding to at least two carriers) belong to the same PUCCH group. Each PUCCH group includes multiple serving cells, specifically including the following situations:

[0085] In the first case, the PUCCH cell (pucch-Cell) parameters of the at least two serving cells are the same.

[0086] In the second case, when the first service cell among the at least two service cells is a special cell of the cell group where the first service cell is located, the PUCCH cell parameters of any one of the at least two service cells except the first service cell indicate the special cell; or any one of the at least two service cells except the first service cell has not been configured with PUCCH cell parameters by the network device.

[0087] In a third case, the first service cell among the at least two service cells is a PUCCH secondary cell, and the PUCCH cell parameters of other service cells among the at least two service cells except the first service cell all indicate the PUCCH secondary cell.

[0088] For example, MCG includes: primary cell 1, secondary cell 2, secondary cell 3 and secondary cell 4. The network device configures the pucch-cell parameters of secondary cell 2 as primary cell 1, the pucch-cell parameters of secondary cell 4 as secondary cell 3, and does not configure the pucch-cell parameters of primary cell 1 and secondary cell 3, implicitly classifying primary cell 1 and secondary cell 2 into one PUCCH group, and classifying secondary cell 3 and secondary cell 4 into one PUCCH group.

[0089] For another example, the MCG includes: primary cell 1, secondary cell 2, secondary cell 3 and secondary cell 4. The network device configures the pucch-cell parameter of secondary cell 2 as primary cell 1, the pucch-cell parameter of secondary cell 3 as secondary cell 3, and the pucch-cell parameter of secondary cell 4 as secondary cell 3, implicitly classifying the primary cell 1 and secondary cell 2 into one PUCCH group, and classifying the secondary cell 3 and secondary cell 4 into one PUCCH group.

[0090] For another example, the MCG includes: primary cell 1, secondary cell 2, secondary cell 3 and secondary cell 4. The network device configures the pucch-cell parameter of secondary cell 4 as secondary cell 3. For primary cell 1, PUCCH feedback is performed on primary cell 1 by default; for secondary cell 2, the pucch-cell parameter is not configured and it is not indicated as a PUCCH secondary cell by other pucch-cell parameters, and it is fed back in primary cell 1 by default; for secondary cell 3, the pucch-cell parameter is not configured but it is indicated as a PUCCH secondary cell by the pucch-cell parameter of secondary cell 4, and it is fed back in secondary cell 3; for secondary cell 4, the pucch-cell parameter is configured and the pucch-cell parameter indicates secondary cell 3, and it is fed back in secondary cell 3; thereby implicitly classifying primary cell 1 and secondary cell 2 into one PUCCH group, and classifying secondary cell 3 and secondary cell 4 into one PUCCH group.

[0100] The ID of the serving cell (of the same cell group) to use for PUCCH. If the field is absent, the UE sends the HARQ feedback on the PUCCH of the SpCell of this cell group, or on this serving cell if it is a PUCCH SCell.

[0101] That is, pucch-Cell is the identifier of the serving cell (within the same cell group) for PUCCH. If the pucch-Cell domain does not exist, the terminal device sends HARQ feedback on the PUCCH of the special cell of the cell group; if the serving cell is a PUCCH secondary cell, HARQ feedback is sent on the serving cell.

[0102] From the above, it can be seen that after considering the feature of supporting one DCI to schedule multiple PDSCH / PUSCHs in multiple cells, naturally, the DCI needs to include indications of the time domain resource allocation of PDSCH / PUSCHs in multiple cells. Then, whether the time domain resource allocation indications of multiple PDSCH / PUSCHs share one indication domain or have independent indication domains, and how to indicate them, are issues that still need to be discussed.

[0103] The present application focuses on the time domain resource allocation indication of multiple PDSCH / PUSCHs, and provides a time domain resource allocation indication method, including the configuration of a TDRA list and an indication method of TDRA.

[0104] In principle, the configuration of the TDRA list in the scenario where one DCI schedules multiple PDSCH / PUSCHs of multiple cells can continue the design idea of ​​"Single Cell Multi-PDSCH / PUSCHscheduling" in the relevant technology, that is, the TDRA list in the relevant technology is expanded, and each TDRA element can indicate the SLIV, PDSCH / PUSCH mapping type, and slot offset K0 / K2 of the PDSCH / PUSCH on one or more cells. However, the difference is that the time domain resource allocation information scheduling of multiple PDSCH / PUSCH in the related technology is only for the same cell, so the configuration of the extended TDRA list in the related technology is only for each cell / each BWP in each cell, while the time domain resource allocation information scheduling of multiple PDSCH / PUSCH considered in this application is for multiple cells, and it can be seen from the above-mentioned related technology that before the terminal device receives the DCI, it does not know which cell combinations are scheduled (because the multiple scheduled cells scheduled by a DCI are indicated by the DCI itself). Therefore, for the scenario where a DCI schedules multiple PDSCH / PUSCHs in multiple cells, if the configuration of the extended TDRA list is used, how many PDSCH / PUSCH TDRAs does each TDRA element in the extended TDRA list contain, and which cells they correspond to, are issues that need to be studied.

[0150] That is, the time domain resource allocation information of each data channel included in the TDRA element corresponds to a cell index of one cell, and the TDRA list is associated with the PUCCH group and / or the cell group.

[0151] In some embodiments, time domain resource allocation information of a data channel corresponding to each cell is determined based on a first TDRA element corresponding to a first value in a TDRA list and / or a cell index of each cell in a scheduled cell set.

[0159] In some embodiments, the time domain resource allocation information of the data channel corresponding to each cell is determined based on at least one of a third TDRA element corresponding to a third value in the TDRA list, a cell index of each cell in the scheduled cell set, and an activated BWP index of each cell.

[0160] In some embodiments, based on the third value, a third TDRA element corresponding to the third value is determined in the TDRA list, and in the third TDRA element, based on the cell index of each cell in the scheduled cell set and the activated BWP index of each cell, the time domain resource allocation information of the data channel corresponding to each cell is determined.

[0167] To summarize, the method provided in this embodiment supports determining the time domain resource allocation information of the data channel of each cell through a TDRA list based on a flexible configuration, and since the configuration of the TDRA list is associated with the first object (including at least two cells), it can meet the TDRA list configuration requirements of different granularities in the scenario where a DCI schedules multiple PDSCH / PUSCHs of multiple cells, saving the resource overhead of configuring the TDRA list during the time domain resource allocation process, and greatly improving the flexibility and pertinence of the configuration and indication during the time domain resource allocation process.

[0177] In some embodiments, the time domain resource allocation information of each data channel in the TDRA element corresponds to a cell index of a cell, which is a cell within the PUCCH group and / or cell group.

For example, the communication protocol predefines TDRA a~b to correspond to cell indexes p~q respectively; or, the network device configures TDRA element 1 to include {cell index x, TDRA y}. For example, the configuration signaling is as follows:

[0198] In some embodiments, the first TDRA list and the second TDRA list are associated with a PUCCH group;

[0199] Or, the first TDRA list is associated with the PUCCH group, and the second TDRA list is associated with the cell group;

[0200] Alternatively, the first TDRA list and the second TDRA list are associated with a cell group.

[0201] In this embodiment, an example is taken in which the first TDRA list is associated with the PUCCH group and the second TDRA list is associated with the cell group.

[0202] In some embodiments, two cell groups configured by the network device through RRC signaling are received, namely MCG and SCG, MCG and SCG each contain 16 cells, MCG contains two PUCCH groups, respectively denoted as PUCCH group 1 (PUCCHgroup 1) and PUCCH group 2 (PUCCH group 2), PUCCH group 1 contains 10 cells (such as cell indexes 1-10), PUCCH group 2 contains 6 cells (such as cell indexes 11-16); SCG contains 1 PUCCH group, denoted as PUCCH group 3 (PUCCHgroup 3), PUCCH group 3 contains 16 cells (such as cell indexes 1-16).

[0203] Receive 3 first TDRA lists and 2 second TDRA lists configured by the network device through RRC signaling. Among them, the 3 first TDRA lists are used to indicate the time domain resource allocation information of PDSCH of PUCCH group 1, PUCCH group 2 and PUCCH group 3 respectively; the 2 second TDRA lists are used to indicate the time domain resource allocation information of PUSCH of MCG and SCG respectively.

[0204] The first TDRA list of the received PUCCH group 1 is shown in Table 1 below:

[0220]

[0221] Step 230: Determine time domain resource allocation information of a data channel corresponding to each cell according to the first TDRA element corresponding to the first value in the TDRA list and / or the cell index of each cell in the scheduled cell set.

[0222] The first value is determined based on the first TDRA indication information. In some embodiments, the first TDRA indication information is sent by the network device to the terminal device.

[0223] In some embodiments, the first TDRA indication information has a first value.

[0224] In some embodiments, the first TDRA indication information is carried in a DCI used for scheduling a PDSCH and / or in a DCI used for scheduling a PUSCH.

[0225] In some embodiments, the cell index of each cell in the scheduled cell set is explicitly indicated by the network device, or is implicitly determined based on the set index of the scheduled cell set. In some embodiments, the cell index is carried in the first indication field of the DCI. In some embodiments, the specific method of implicit determination may be predefined by the communication protocol or configured by the network device.

[0226] In some embodiments of the present application, implicitly determining the cell index based on the set index means that there is a corresponding relationship between the set index and the cell index. After the terminal device obtains the set index, the cell index can be queried in the corresponding relationship according to the set index.

[0227] In some embodiments, the set index of the scheduled cell set is indicated by the network device. In some embodiments, the set index is carried in the first indication field of the DCI.

[0228] In some embodiments, a first TDRA element corresponding to the first value is determined in the TDRA list, and time domain resource allocation information of a data channel corresponding to each cell is determined based on the first TDRA element.

[0229] In some embodiments, based on the cell index of each cell in the scheduled cell set, time domain resource allocation information of a data channel corresponding to each cell is determined.

[0230] In some embodiments, according to the first value, a first TDRA element corresponding to the first value is determined in the TDRA list, and in the first TDRA element, based on the cell index of each cell in the scheduled cell set, the time domain resource allocation information of the data channel corresponding to each cell is determined.

[0231] Exemplarily, a DCI scheduling PDSCH is received, and the DCI carries first indication information for indicating the PDSCH scheduling of cell 1 and cell 5 in PUCCH group 1. Rows 1 to 16 in the TDRA list correspond one by one to values ​​0 to 15 in the first indication field, and the first value is 1.

[0232] Then, the PDSCH time domain resource allocation information of cell 1 and cell 5 is indicated by the following information: According to the first value of 1, the second row (TDRA element 2) in the first TDRA list of PUCCH group 1 (i.e., Table 1) is determined, and the TDRA 201 corresponding to cell 1 and the TDRA 205 corresponding to cell 5 are determined in the second row. The terminal device ignores the TDRAs corresponding to other cell indexes in the second row of Table 1, such as TDRA 202-204, TDRA 206-210.

[0233] To summarize, the method provided in this embodiment determines the time domain resource allocation information of the data channel of the scheduled cell through the TDRA list configured in association with the PUCCH group and / or cell group. Each TDRA element in the TDRA list contains the time domain resource allocation information of the data channels of all cells in all PUCCH groups and / or cell groups, which greatly saves the signaling overhead in the time domain resource allocation process.

[0234] Method 2: Case 1 + Case B

[0235] Figure 3 A flow chart of a method for configuring time domain resource allocation provided by an exemplary embodiment of the present application is shown. Taking the method executed by a terminal device as an example, the method includes at least some of the following steps:

[0236] Step 310: Receive the configuration of the TDRA list;

[0237] The configuration may be sent by the network device through high-layer signaling, where the high-layer signaling includes: SIB, or RRC, or MAC signaling.

[0238] In this embodiment, the TDRA list is associated with a cell combination, the cell combination includes at least two cells, and the TDRA elements in the TDRA list include time domain resource allocation information of data channels corresponding to each cell in the cell combination. In some embodiments, it can also be understood that the TDRA list is configured with a cell combination as the granularity, the cell combination includes at least two cells, and each TDRA element in each TDRA list includes time domain resource allocation information of data channels corresponding to all cells in the cell combination.

[0239] In some embodiments, the TDRA element in the TDRA list includes time domain resource allocation information of a data channel of each of N cells, where N is the number of cells in the cell group.

[0240] In some embodiments, the time domain resource allocation information of each data channel in the TDRA element corresponds to a cell index of a cell, which is a cell in the cell group.

[0241] In this embodiment, the TDRA list may include a first TDRA list and a second TDRA list, wherein the first TDRA list is used to indicate the time domain resource allocation information of the PDSCH, and the second TDRA list is used to indicate the time domain resource allocation information of the PUSCH. Then the TDRA element in the first TDRA list includes the time domain resource allocation information of N PDSCHs, and each time domain resource allocation information of the PDSCH corresponds to a cell index; the TDRA element in the second TDRA list includes the time domain resource allocation information of N PUSCHs, and each time domain resource allocation information of the PUSCH corresponds to a cell index.

[0242] In some embodiments, the first TDRA list and the second TDRA list are associated with a cell combination. In some embodiments, the cell combination associated with the first TDRA list and the cell combination associated with the second TDRA list are the same or different.

[0243] In some embodiments, the correspondence between the time domain resource allocation information of each PDSCH or the time domain resource allocation information of each PUSCH and the cell index is predefined by the communication protocol or configured by the network device. For example, the communication protocol predefines that TDRA a~b correspond to cell indexes p~q respectively; or the network device configures TDRA element 1 to include {cell index x, TDRA y}.

[0244] Exemplarily, two cell groups are received by the network device through RRC signaling, namely MCG and SCG, MCG and SCG each contain 16 cells, MCG contains two PUCCH groups, respectively recorded as PUCCH group 1 (PUCCH group 1) and PUCCH group 2 (PUCCH group 2), PUCCH group 1 contains 10 cells (such as cell indexes 1-10), and PUCCH group 2 contains 6 cells (such as cell indexes 11-16); SCG contains 1 PUCCH group, recorded as PUCCH group 3 (PUCCH group 3), PUCCH group 3 contains 16 cells (such as cell indexes 1-16).

[0245] Taking PUCCH group 1 as an example, PUCCH group 1 includes 4 cell combinations, namely:

[0246] Cell combination 1: Cell 1+Cell 2+Cell 3;

[0247] Cell combination 2: Cell 4+Cell 5+Cell 6;

[0248] Cell combination 3: Cell 7 + Cell 8;

[0249] Cell combination 4: Cell 9 + Cell 10.

[0250] Receive 4 first TDRA lists or 4 second TDRA lists configured by the network device for PUCCH group 1 through RRC signaling, wherein the 4 first TDRA lists are respectively used to indicate the time domain resource allocation information of PDSCH of cell combination 1, cell combination 2, cell combination 3, and cell combination 4, or the 4 second TDRA lists are respectively used to indicate the time domain resource allocation information of PUSCH of cell combination 1, cell combination 2, cell combination 3, and cell combination 4. This embodiment is schematically described by taking the reception of 4 first TDRA lists as an example.

[0264] The second value is determined based on the second TDRA indication information. In some embodiments, the second TDRA indication information is sent by the network device to the terminal device.

[0265] In some embodiments, the second TDRA indication information has a second value.

[0266] In some embodiments, the second TDRA indication information is carried in a DCI used for scheduling a PDSCH and / or in a DCI used for scheduling a PUSCH.

[0267] In some embodiments, the cell index of each cell in the scheduled cell set is explicitly indicated by the network device, or is implicitly determined based on the set index of the scheduled cell set. In some embodiments, the cell index is carried in the first indication field of the DCI. In some embodiments, the specific method of implicit determination may be predefined by the communication protocol or configured by the network device.

[0268] In some embodiments, the set index of the scheduled cell set is indicated by the network device. In some embodiments, the set index is carried in the first indication field of the DCI.

[0269] In some embodiments, a second TDRA element corresponding to the second value is determined in the TDRA list, and time domain resource allocation information of a data channel corresponding to each cell is determined based on the second TDRA element.

[0270] In some embodiments, time domain resource allocation information of a data channel corresponding to each cell is determined based on a set index of a scheduled cell set.

[0271] In some embodiments, based on the cell index of each cell in the scheduled cell set, time domain resource allocation information of a data channel corresponding to each cell is determined.

[0272] In some embodiments, a TDRA list is determined based on the set index of the scheduled cell set, and based on the second value, a second TDRA element corresponding to the second value is determined in the TDRA list, and in the first TDRA element, based on the cell index of each cell in the scheduled cell set, the time domain resource allocation information of the data channel corresponding to each cell is determined.

[0273] Exemplarily, a DCI scheduling PDSCH is received, and the DCI carries second indication information for indicating the PDSCH scheduling of cell combination 1 (i.e., cell 1 + cell 2 + cell 3) in PUCCH group 1. The 1st to 16th rows in the TDRA list correspond one by one to the values ​​0 to 15 in the first indication field, and the second value is 1.

[0274] The PDSCH time domain resource allocation information of cell combination 1 is determined by the following information: Table 6 is determined according to cell combination 1, and the second row (TDRA element 2) in Table 6 is determined according to the second value of 1, and TDRA201 corresponding to cell 1, TDRA 202 corresponding to cell 2, and TDRA 203 corresponding to cell 3 are determined in the second row.

[0275] To sum up, the method provided in this embodiment determines the time domain resource allocation information of the scheduled cell through the TDRA list configured in association with the cell combination. Each TDRA element in each TDRA list only contains the time domain resource allocation information of the data channels of all cells in the cell combination, which greatly improves the flexibility of configuration and scheduling in the time domain resource allocation process.

[0300] The third value is determined based on the third TDRA indication information. In some embodiments, the third TDRA indication information is sent by the network device to the terminal device.

[0301] In some embodiments, the third TDRA indication information has a third value.

[0302] In some embodiments, the third TDRA indication information is carried in a DCI used for scheduling a PDSCH and / or in a DCI used for scheduling a PUSCH.

In some embodiments, the BWP index is carried in the first indication field of the DCI. In some embodiments, the specific method of implicit determination may be predefined by a communication protocol or configured by a network device.

[0306] In some embodiments, a third TDRA element corresponding to a third value is determined in the TDRA list, and time domain resource allocation information of a data channel corresponding to each cell is determined based on the third TDRA element.

[0307] In some embodiments, based on the cell index of each cell in the scheduled cell set, time domain resource allocation information of a data channel corresponding to each cell is determined.

[0308] In some embodiments, based on the activated BWP index of each cell in the scheduled cell set, the time domain resource allocation information of the data channel corresponding to each cell is determined.

[0312] Then the PDSCH time domain resource allocation information of cell 11BWP2 and cell 13BWP2 is indicated by the following information: According to the third value of 2, the third row (TDRA element 3) in the first TDRA list of PUCCH group 2 (i.e., Table 10) is determined, and the TDRA 311-2 corresponding to cell 11BWP2 and the TDRA 313-2 corresponding to cell 13BWP2 are determined in the third row. The terminal device ignores the TDRAs corresponding to other cell indices and BWP indices in the third row of Table 10.

[0313] To summarize, the method provided in this embodiment configures a TDRA list in association with a PUCCH group and / or a cell group, and takes into account the situation when each cell contains multiple BWPs. Each TDRA element in the TDRA list contains the time domain resource allocation information of the data channels of all cells and their BWPs in all PUCCH groups and / or cell groups, which saves the signaling overhead in the time domain resource allocation process and further improves the flexibility of configuration and scheduling in the time domain resource allocation process.

[0427] To sum up, the method provided in this embodiment facilitates the terminal device to determine the time domain resource allocation information of the data channel of each cell by flexibly configuring the TDRA list.

In some embodiments, the correspondence between the target value and n is configured by the network device through high-level signaling, or predefined by the communication protocol. In some embodiments, the correspondence between the target value and n for different cells or different BWPs may be the same or different. For example, the target value is m, indicating the TDRA element in the nth row of the received 64 first TDRA lists, n=m or n=m+1.

[0441] In some embodiments, the cell index of each cell in the scheduled cell set is explicitly indicated by the network device, or is implicitly determined based on the set index of the scheduled cell set. In some embodiments, the cell index is carried in the first indication field of the DCI. In some embodiments, the specific method of implicit determination may be predefined by the communication protocol or configured by the network device.

[0442] In some embodiments, the set index of the scheduled cell set is explicitly indicated by the network device. In some embodiments, the set index is carried in the first indication field of the DCI.
