Description

Information sending method, information receiving method and device Technical Field

[0001] The present application relates to the field of communication technology. Background Art

[0002] The new wireless NR supports spectrum in different frequency domains. At present, it is foreseeable that 5G will have more available spectrum due to re-farming of frequency bands originally used for previous generation networks. Among them, for the low-frequency FR1 band, the available spectrum blocks may be more scattered and the bandwidth is narrower. On the other hand, for the frequency band range FR2 band and some frequency band range FR1 bands, since the available spectrum in the same band will be wider, intra-band multi-carrier operation is necessary. Therefore, considering the needs of different spectrums, in order to improve network throughput and good coverage, it is necessary to ensure that these scattered spectrums or large bandwidth spectrums are used in a more efficient and flexible manner, for example, by improving the flexibility and spectrum / power efficiency of scheduling data in multiple cells.

[0003] In the current scheduling mechanism, a single downlink control information (DCI) is only allowed / supported to schedule the physical uplink shared channel (PUSCH) or the physical downlink shared channel (PDSCH) of a single cell. Considering the aforementioned available fragmented spectrum or large bandwidth spectrum, one approach is to further support the scheduling of PUSCH or PDSCH of multiple cells by the same scheduling DCI, thereby improving flexibility and efficiency and reducing control overhead. Therefore, one of the goals of multi-carrier enhancement in Rel-18 is to support the scheduling of PUSCH / PDSCH of multiple cells by a single DCI, where only one PDSCH or PUSCH is scheduled for a cell.

[0004] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0005] Summary of the Invention

[0006] Currently, in order to save power consumption of terminal devices, cells can be indicated as deactivated or dormant. In the Rel-18 under discussion, in order to support scheduling multiple cells through a single DCI, new DCI formats (DCI formats) for scheduling PUSCH and PDSCH will be introduced. Currently, it has been agreed that the DCI formats can also be used to indicate cell dormancy, but in the case of cell deactivation and / or dormancy, how to use the DCI formats for scheduling, how to receive the DCI formats, and the PDSCH or PUSCH scheduled by the DCI formats are still under discussion.

[0007] In response to at least one of the above problems, embodiments of the present application provide an information sending method, an information receiving method, and an apparatus.

[0008] According to one aspect of an embodiment of the present application, there is provided an information sending device, applied to a network device, the device comprising: a transmitter, or a transmitter and a receiver;

[0009] The transmitter transmits, in a scheduling cell, a first downlink control information format (DCI format) for scheduling a physical downlink shared channel (PDSCH) of one or more cells in a first cell set and / or a second DCI format for scheduling a physical uplink shared channel (PUSCH) of one or more cells in a second cell set;

[0010] The transmitter further transmits a PDSCH in some or all of the cells scheduled by the first DCI format, and / or the receiver receives a PUSCH in some or all of the cells scheduled by the second DCI format.

[0011] According to another aspect of an embodiment of the present application, there is provided an information receiving apparatus, applied to a terminal device, the apparatus comprising: a receiver, or a receiver and a transmitter;

[0012] The receiver monitors and / or receives, in a scheduling cell, a first downlink control information format (DCI format) of a physical downlink shared channel (PDSCH) for scheduling one or more cells in a first cell set and / or a second DCI format of a physical uplink shared channel (PUSCH) for scheduling one or more cells in a second cell set;

[0013] The receiver further receives a PDSCH in some or all of the cells scheduled by the first DCI format, and / or the transmitter transmits a PUSCH in some or all of the cells scheduled by the second DCI format.

[0014] According to another aspect of an embodiment of the present application, a communication system is provided, including: the terminal device of the aforementioned aspect and / or the network device of the aforementioned aspect.

[0015] One of the beneficial effects of the embodiments of the present application is that, when a cell is deactivated and / or dormant, a terminal device monitors and / or receives, or does not monitor and / or receive, a DCI format supporting the scheduling of a PDSCH or PUSCH for multiple cells, and the PDSCH or PUSCH scheduled by the DCI format. This can achieve multi-carrier enhancement while saving power consumption of the terminal device and improving resource efficiency.

[0052] The following describes various implementations of the present application in conjunction with the accompanying drawings. These implementations are merely illustrative and are not intended to limit the present application.

[0053] Embodiments of the first aspect

[0054] An embodiment of the present application provides a method for receiving information, which is described from the perspective of a terminal device.

[0055] FIG2 is a schematic diagram of an information receiving method according to an embodiment of the present application. As shown in FIG2 , the method includes:

[0056] 201. Monitoring and / or receiving, in a scheduling cell, a first downlink control information format (DCI format) of a physical downlink shared channel (PDSCH) for scheduling one or more cells in a first cell set and / or a second DCI format of a physical uplink shared channel (PUSCH) for scheduling one or more cells in a second cell set.

[0057] 202. Receive a PDSCH in some or all of the cells scheduled by the first DCI format, and / or send a PUSCH in some or all of the cells scheduled by the second DCI format.

[0058] It is worth noting that FIG2 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG2 above.

[0059] In some embodiments, the first DCI format is DCI format 1_3, and the second DCI format is DCI format 0_3. In the following description, the DCI format can be replaced by DCI format or DCI or DCI using DCI format, etc. The CRC of the first DCI format and / or the second DCI format is scrambled by C-RNTI or MCS-C-RNTI. The first DCI format is used for scheduling one PDSCH in one cell, or multiple PDSCHs in multiple cells and each cell corresponds to one PDSCH (is used for the scheduling of one PDSCH in one cell, or multiple PDSCHs in multiple cells with one PDSCH per cell); the second DCI format is used for scheduling one PUSCH in a first cell, or multiple PUSCHs in multiple cells and each cell corresponds to one PUSCH (is used for the scheduling of one PUSCH in one cell, or multiple PUSCHs in multiple cells with one PUSCH per cell).

[0060] In some embodiments, the terminal device may be configured to monitor / receive the first DCI format and / or the second DCI format on the scheduling cell.

[0061] In some embodiments, the scheduling cell may be a SpCell (or primary cell, i.e., Pcell or PScell) or a SCell (of an MCG or SCG). The service cell configuration information of the scheduling cell includes an eighth high-level parameter for configuring the terminal device to monitor and / or receive the first DCI format and / or the second DCI format in the scheduling cell. For example, the eighth high-level parameter is included in the search space information (SearchSpace) in the service cell configuration information. That is, whether the terminal device monitors DCI format 1_3 and / or DCI format 0_3 in the scheduling cell is configured per SearchSpace. For example, for a UE-specific search space (i.e., USS) configured by SearchSpace, the terminal device can be configured to monitor DCI format 1_3 and / or DCI format 0_3 in the SearchSpace. The Search space(s) used to monitor DCI format 1_3 or DCI format 0_3 may be the same or different. Among them, the search space information is, for example, configured per BWP, that is, included in the BWP configuration information.

[0062] In some embodiments, the serving cell configuration information of the scheduling cell includes an eleventh high-level parameter (egMC-DCI-SetofCellsToAddModList) for configuring a list of cell sets, the eleventh high-level parameter includes one or more twelfth high-level parameters (egMC-DCI-SetofCells) for configuring the cell set, one twelfth high-level parameter includes a thirteenth high-level parameter (cell set identifier, egsetofCellsID) for configuring the cell set ID, including or excluding information for configuring a (scheduled) cell list for a first DCI format (cell set for a first DCI format) (ScheduledCell-ListDCI-1-3, a first high-level parameter), including or excluding information for configuring a (scheduled) cell list for a second DCI format (cell set for a second DCI format) The first high-level parameter and the second high-level parameter respectively indicate the scheduled cell list (cell set) by indicating the serving cell index of the cell. For example, the first high-level parameter and the second high-level parameter respectively indicate at least 2 and at most 4 (i.e., 2 to 4) serving cell indices (serving cell indexes). A twelfth high-level parameter includes or does not include information for configuring a (scheduled) cell combination list for the first DCI format (scheduledCellCombo-ListDCI-1-3, a third high-level parameter), and includes or does not include information for configuring a (scheduled) cell combination list for the second DCI format (scheduledCellCombo-ListDCI-0-3, a fourth high-level parameter). The third high-level parameter and the fourth high-level parameter respectively include one or more fourteenth high-level parameters (e.g., ScheduledCellCombo) (entry) for configuring a cell combination. The cell combination information may correspond to the first DCI format or the second DCI format, as shown in FIG3 .

[0063] In some embodiments, a high-level parameter for configuring a list (e.g., the eleventh high-level parameter, the first high-level parameter, the second high-level parameter, the third high-level parameter, the fourth high-level parameter) includes another high-level parameter for configuring the list, which can also be referred to as an entry.

[0064] In some embodiments, the cell sets configured in different twelfth higher layer parameters include (completely) different cells, i.e., there is no intersection. In other words, the cell sets associated with / corresponding to different cell set identifiers include (completely) different cells, i.e., there is no intersection.

[0065] In some embodiments, the cells included in the cell set configured by the first higher-layer parameter and the cell set configured by the second higher-layer parameter in the same twelfth higher-layer parameter are completely identical or partially identical, and / or the cell set configured by the first higher-layer parameter and the cell set configured by the second higher-layer parameter in the same twelfth higher-layer parameter include at least one identical cell. In other words, the cells included in the cell set associated with / corresponding to the same cell set identifier are completely identical or partially identical.

[0066] In some embodiments, the first DCI format is used to schedule PDSCH(s) in one or more cells in a first cell set, and the second DCI format is used to schedule PUSCH(s) in one or more cells in a second cell set, wherein "used for scheduling" means that scheduling is supported or can be scheduled, can be actually scheduled or not actually scheduled, and the first cell set and / or the second cell set are the scheduled cell sets.

[0067] In some embodiments, the scheduled cell set is indicated by a fourth information field (scheduled cell set indicator) in the first DCI format and / or the second DCI format, and / or is configured by a higher layer parameter.

[0068] In some embodiments, the fourth information field (Scheduled cell set indicator) is used to indicate a scheduled cell set. For example, in a first DCI format, the fourth information field indicates a scheduled first cell set from one or more cell sets (for the first DCI format) configured by (the eleventh higher layer parameter). In a second DCI format, the fourth information field indicates a scheduled second cell set from one or more cell sets (for the second DCI format) configured by (the eleventh higher layer parameter).

[0069] In some embodiments, the fourth information field includes Special, among which, N set It is the number of cell sets configured by the eleventh higher layer parameter (e.g., MC-DCI-SetofCellsToAddModList) (or the number of the included twelfth higher layer parameters and / or the number of configured cell set identifiers). For example, the relationship between the value of the fourth information field and the indicated scheduled cell set is shown in Table 1 below. When the value of the fourth information field is 0 (decimal), the scheduled cell set is the cell set configured by the first entry of the eleventh higher layer parameter configuration.

[0070] In some embodiments, for the first DCI format, (if some of the entries in the eleventh higher layer parameter only configure a cell set for the second DCI format), the UE does not expect the fourth information field to provide an index corresponding to an entry that only includes a cell set configured for the second DCI format or an index corresponding to an entry that does not include a cell set configured for the first DCI format.

[0071] Table 1

[0072] In some embodiments, the fourth information field in the first DCI format includes bits, where N set1 It is the number of cell sets for the first DCI format configured by the eleventh high-level parameter (egMC-DCI-SetofCellsToAddModList). For example, the relationship between the value of the fourth information field and the indicated first scheduled cell set is shown in Tables 2 and 3 below. When the value of the fourth information field is 0 (decimal), the scheduled cell set is the cell set (for the first DCI format) configured by the first entry configured with the first or second high-level parameter (or the cell set for the first DCI format) configured by the eleventh high-level parameter, or in other words, the first cell set. The fourth information field in the second DCI format includes bits, where N set2 It is the number of cell sets for the second DCI format configured by the eleventh higher layer parameter (e.g., MC-DCI-SetofCellsToAddModList). For example, the relationship between the value of the fourth information field and the indicated scheduled (second) cell set is shown in Tables 2 and 3 below. When the value of the fourth information field is 0 (decimal), the scheduled cell set is the cell set (for the first DCI format) configured by the first entry configured with the first or second higher layer parameter (or the cell set for the first DCI format) configured by the eleventh higher layer parameter, or in other words, the second cell set.

[0073] Table 2

[0074] Table 3

[0075] In some embodiments, the fourth information field indicates the scheduled cell set by indicating or based on the cell set identifier (configured by the thirteenth high-level parameter). For example, for the first DCI format, the value of the fourth information field is equal to the value of the cell set ID associated / corresponding to the scheduled cell set (first cell set). When the value of the fourth information field is 0 (decimal), the scheduled cell set (first cell set) is the cell set associated / corresponding to cell set ID=0. For the second DCI format, the value of the fourth information field is equal to the value of the cell set ID corresponding to the scheduled cell set (second cell set). When the value of the fourth information field is 0 (decimal), the scheduled cell set (second cell set) is the second cell set corresponding to cell set ID=0.

[0076] In some embodiments, the first DCI format and / or the second DCI format may not include the fourth information field, and the scheduled cell set may be determined according to higher layer parameters.

[0077] For example, when the eleventh higher-layer parameter includes only one twelfth higher-layer parameter, the first DCI format and the second DCI format do not include the fourth information field. If the twelfth higher-layer parameter includes the first higher-layer parameter, for the first DCI format, the corresponding scheduled cell set is the cell set configured by the twelfth higher-layer parameter or the first higher-layer parameter. If the twelfth higher-layer parameter includes the second higher-layer parameter, for the second DCI format, the corresponding scheduled cell set is the cell set configured by the twelfth higher-layer parameter or the second higher-layer parameter.

[0078] For example, when the eleventh high-level parameter only includes a twelfth high-level parameter that includes the first high-level parameter, the first DCI format does not include the fourth information field. For the first DCI format, its corresponding scheduled cell set is the cell set configured by the twelfth high-level parameter or the first high-level parameter.

[0079] For example, when the eleventh high-level parameter only includes a twelfth high-level parameter that includes the second high-level parameter, the second DCI format does not include the fourth information field. For the second DCI format, its corresponding scheduled cell set is the cell set configured by the twelfth high-level parameter or the second high-level parameter.

[0080] In some embodiments, the first cell set and the second cell set are associated with / correspond to the same cell set identifier. For example, the cell set identifier associated with / corresponds to the first cell set or the second cell set is a cell set ID configured with a thirteenth high-level parameter in a twelfth high-level parameter including a first high-level parameter for configuring the first cell set or a second high-level parameter for configuring the second cell set. That is, the first cell set and the second cell set are cell sets configured with the first high-level parameter and the second high-level parameter in the same twelfth high-level parameter. The monitoring and / or reception of the first DCI format and / or the second DCI format is based on a cell set identifier. For different cell set identifiers, the terminal device monitors and / or receives different first DCI formats and / or second DCI formats, or in other words, the terminal device monitors and / or receives the first DCI format and / or the second DCI format corresponding to a cell set identifier. For example, for different cell set identifiers or the first cell set and / or the second cell set associated with different cell set identifiers, the size of the corresponding first DCI format and / or the second DCI format is different, and / or the search space and / or CORESET configuration used for monitoring and / or receiving the corresponding first DCI format and / or the second DCI format is different, and / or the corresponding reference cell is different.

[0081] In some embodiments, since the cells included in the cell set configured by the first high-level parameter and the cell set configured by the second high-level parameter in the same twelfth high-level parameter (cell set identifier) ​​are completely identical or partially identical, and / or the cell set configured by the first high-level parameter and the cell set configured by the second high-level parameter in the same twelfth high-level parameter include at least one identical cell, the first cell set and the second cell set correspond to the same cell set identifier, therefore, the cells in the first cell set and the second cell set are completely identical or partially identical, and / or the first cell set and the second cell set include at least one identical cell (for example, at least one identical cell includes a reference cell). A first cell set and a second cell set each include at most four cells.

[0082] The above describes how to indicate / configure a scheduled cell set. One or more cells scheduled by the first DCI format and / or the second DCI format in the scheduled cell set are indicated by the second information field and / or the third information field in the first DCI format and / or the second DCI format. The following example illustrates this. The following third and fourth higher-layer parameters (if any) are included in the twelfth higher-layer parameter corresponding to the scheduled cell set.

[0083] In some embodiments, the second information field may be a frequency domain resource assignment field, which is used to indicate frequency domain resource assignment. For example, for the first DCI format, the frequency domain resource assignment field includes: information blocks, information block 1, information block 2, ..., information block in, For example, it is / is equal to the number of cells in the scheduled cell combination (first cell combination) or the scheduled cell set (first cell set). The scheduled first cell combination is indicated by the third information field in the first DCI format or configured by the third high-level parameter (when the first DCI format does not include the third information field). The indication method of the scheduled cell set is as described above. For example, when (for the scheduled cell set) the (corresponding) first cell combination list (or the third high-level parameter) is not configured, is equal to the number of cells in the scheduled cell set, when the (corresponding) first cell combination list (or the third higher layer parameter) is configured (for the first scheduled cell set), is equal to the number of cells in the scheduled cell combination, but is not limited thereto. Wherein, each information block corresponds to ( The information blocks are arranged in ascending order of the cell index (e.g., the serving cell index and / or the second index) (of the scheduled cell combination or the cells in the scheduled cell set). For example, information block 1 (the first information block) corresponds to the frequency domain resource allocation for the cell with the smallest cell index, information block 2 (the second information block) corresponds to the frequency domain resource allocation for the cell with the next smallest cell index (the second smallest), and so on.

[0084] For example, for the second DCI format, the frequency domain resource allocation field includes information blocks, information block 1, information block 2, ..., information block in, For example, it is / is equal to the number of cells in the scheduled cell combination (second cell combination) or the scheduled cell set (second cell set). The scheduled cell combination is indicated by the third information field in the second DCI format or configured by the fourth high-level parameter (when the first DCI format does not include the third information field). The indication method of the scheduled cell set is as described above. For example, when (for the scheduled cell set) no (corresponding) cell combination list (or fourth high-level parameter) is configured, is equal to the number of cells in the scheduled cell set. When the (corresponding) cell combination list (or the fourth higher layer parameter) is configured (for the scheduled cell set), is equal to the number of cells in the scheduled cell combination, but is not limited thereto. Wherein, each information block corresponds to ( The information blocks are arranged in ascending order of the cell index (for example, the serving cell index and / or the second index) (of the cells in the scheduled second cell combination or the scheduled second cell set). For example, information block 1 (the first information block) corresponds to the frequency domain resource allocation for the cell with the smallest cell index, information block 2 (the second information block) corresponds to the frequency domain resource allocation for the cell with the second smallest cell index (the second smallest), and so on.

[0085] For example, if the information for configuring the cell combination list for the first DCI format (eg, the third higher layer parameter ScheduledCellCombo-ListDCI-1-3) is configured with more than one entry or if the DCI format includes a third information field, is equal to the number of scheduled cells indicated by the third information field in the DCI format, if the information for configuring the cell combination list (e.g., ScheduledCellCombo-ListDCI-1-3) for the DCI format is configured with (or includes only) one entry, Equal to the number of cells configured by the third higher-layer parameter (e.g., ScheduledCellCombo-ListDCI-1-3) or the entry included in the third higher-layer parameter or the IE (e.g., ScheduledCellCombo) for configuring the scheduled cell combination, otherwise (or if the DCI format does not include the third information field and / or is not provided) It is equal to the number of cells in the scheduled cell set configured by the information used to configure the scheduled cell set (eg the first higher layer parameter ScheduledCell-ListDCI-1-3).

[0086] For example, if the information for configuring the cell combination list for the second DCI format (eg, the fourth higher layer parameter ScheduledCellCombo-ListDCI-0-3) is configured with more than one entry or if the DCI format includes a third information field, is equal to the number of scheduled cells indicated by the third information field in the DCI format, if the information for configuring the cell combination list for the DCI format (the fourth higher-layer parameter e.g., ScheduledCellCombo-ListDCI-0-3) is configured with (or includes only) one entry, Equal to the number of cells configured by the fourth higher layer parameter (e.g., ScheduledCellCombo-ListDCI-0-3) or the entry included in the fourth higher layer parameter or the IE (e.g., ScheduledCellCombo) for configuring the scheduled cell combination, otherwise (or if the DCI format does not include the third information field and / or is not provided) It is equal to the number of cells in the scheduled cell set configured by the information used to configure the scheduled cell set (eg the second higher layer parameter ScheduledCell-ListDCI-0-3).

[0087] In some embodiments, the second information field may be used to indicate scheduled cells and / or unscheduled cells (in a scheduled cell set or a scheduled cell combination). In other words, the second information field (Frequency domain resource assignment) is used to indicate frequency domain resource allocation and / or scheduled cells and / or unscheduled cells (in a scheduled cell set or a scheduled cell combination).

[0088] For example, the second information field in the first DCI format and / or the second DCI format indicates scheduled cells and / or unscheduled cells from the scheduled cell set (the first cell set and / or the second cell set). Assuming that the scheduled cell set includes four cells, the second information field includes four information blocks (block number 1, block number 2, block number 3, and block number 4), which correspond to the four cells one by one. If all bits in the information block corresponding to a cell are set to a specific value, the cell is not scheduled; otherwise, the cell is scheduled. For example, for (a bit in) an information block, the specific value is 0 or 1. For example, if the resource allocation type corresponding to the cell corresponding to an information block is RA Type 0, the specific value for the information block is 0; if the resource allocation type corresponding to the cell corresponding to the information block is RA Type 1, the specific value for the information block is 1; if the resource allocation type corresponding to the cell corresponding to the information block is dynamic RA Type, the specific value for the information block is 0 or 1.

[0089] For another example, the second information field in the first DCI format and / or the second DCI format indicates the scheduled cells and / or unscheduled cells from the scheduled cell combination (indicated by the third information field or configured by the third high-level parameter (when the third information field is not included in the first DCI format)). Assuming that the scheduled first cell combination includes 4 cells, the second information field includes 4 information blocks, which correspond to the 4 cells one by one. If all bits in the information block corresponding to a cell are set to the specific value, the cell is not scheduled; otherwise, the cell is scheduled. For example, as shown in Table 4 below, only the bits in information block 1 are not set to the specific value, and the cell corresponding to information block 1, i.e., Cell 0, is indicated by the second information field as a scheduled cell, and / or, while the other cells are indicated by the second information field as unscheduled cells.

[0090] Table 4

[0091] In some embodiments, when the first DCI format or the second DCI format includes the third information field, the second information field is not used to indicate scheduled cells and / or unscheduled cells.

[0092] In some embodiments, when the first DCI format or the second DCI format includes a third information field, the second information field is used to indicate scheduled cells and / or unscheduled cells in the cell combination indicated by the third information field.

[0093] In some embodiments, the second information field is further used to indicate which information blocks in one or more other information fields are used to indicate Scell ​​sleep. For example, these information blocks are used to indicate Scell ​​sleep per Scell, but the present invention is not limited thereto. How to indicate SCell sleep will be described later.

[0094] In some embodiments, the third information field (Scheduled cells indicator) is used to indicate scheduled cells (or, to indicate a scheduled cell combination). For example, in a first DCI format, the third information field indicates the scheduled cells from a scheduled cell set (a first cell set) (by indicating a first cell combination). For another example, in a second DCI format, the third information field indicates the scheduled cells from a scheduled cell set (a second cell set) (by indicating a second cell combination).

[0095] In some embodiments, the first DCI format and / or the second DCI format includes or does not include the third information field.

[0096] For example, for the first DCI format, when the third high-level parameter (eg ScheduledCellCombo-ListDCI-1-3) (for / corresponding to the scheduled cell set (first cell set)) is not configured (or, when the scheduled cell set does not include a cell combination list), the third information field does not exist, or the number of bits is 0. Otherwise, the number of bits is To indicate the scheduled cell from the scheduled cell set (or to indicate the first cell combination from the first cell combination list (in the first cell set)), wherein I DL For example, the number of entries configured by ScheduledCellCombo-ListDCI-1-3 (that is, the number of the fourteenth high-level parameters it includes). If ScheduledCellCombo-ListDCI-1-3 is configured with only one entry, the scheduled cell is the cell configured by ScheduledCellCombo-ListDCI-1-3.

[0097] For example, for the second DCI format, when the fourth higher layer parameter (egScheduledCellCombo-ListDCI-0-3) (for / corresponding to the scheduled cell set (the second cell set)) is not configured (or, when the scheduled cell set does not include a cell combination list), the third information field does not exist, or the number of bits is 0. Otherwise, the number of bits is To indicate the scheduled cell from the scheduled cell set (or to indicate the second cell combination from the second cell combination list (in the second cell set), wherein I UL For example, the number of entries configured by ScheduledCellCombo-ListDCI-0-3 (that is, the number of the fourteenth high-level parameters it includes). If ScheduledCellCombo-ListDCI-0-3 is configured with only one entry, the scheduled cell is the cell configured by ScheduledCellCombo-ListDCI-0-3.

[0098] In some embodiments, the scheduling cell belongs to or does not belong to the first cell set, and / or the scheduling cell belongs to or does not belong to the second cell set. The scheduling cell is used to send DCI format 1_3 for scheduling (cells in) the first cell set and / or to send DCI format 0_3 for scheduling (cells in) the second cell set. In addition, for the convenience of explanation, a reference cell is proposed in an embodiment of the present application. For a cell set, the (corresponding) reference cell is a cell in the cell set (the first cell set and / or the second cell set). For example, for cell sets associated / corresponding to the same cell set identifier, the reference cells are the same; otherwise, the reference cells are different. For example, the reference cells of the above-mentioned first cell set and / or second cell set (associated with the same cell set identifier) ​​are the same. Alternatively, one cell set identifier corresponds to one reference cell (a one-to-one correspondence between the cell set identifier and the reference cell), but is not limited thereto. The one cell is a scheduling cell or a cell in the cell set that is different from the scheduling cell. For example, when the cell set includes a scheduling cell, the reference cell can be the scheduling cell or a cell in the cell set that is different from the scheduling cell. When the cell set does not include a scheduling cell, the reference cell is a cell in the cell set (different from the scheduling cell), that is, the reference cell is not a scheduling cell. Figure 4 is a schematic diagram of the relationship between the scheduling cell, reference cell, and cell set according to an embodiment of the present application. As shown in a of Figure 4, the first cell set and the second cell set include a scheduling cell, and the reference cell is the scheduling cell. As shown in b of Figure 4, the first cell set does not include a scheduling cell, and the reference cell is a cell in the first cell set. As shown in c of Figure 4, the first cell set and the second cell set do not include a scheduling cell, and the reference cell is a cell in the first cell set and the second cell set.

[0099] That is, the scheduling cell and reference cell include the following situations:

[0100] Case 1: the scheduling cell belongs to the first cell set and / or the second cell set, and the reference cell is the scheduling cell;

[0101] Case 2: the scheduling cell belongs to the first cell set and / or the second cell set, and the reference cell is not the scheduling cell, but a cell in the first cell set and / or the second cell set that is different from the scheduling cell;

[0102] Case 3: The scheduling cell does not belong to the first cell set and / or the second cell set, and the reference cell is a cell in the first cell set and / or the second cell set (since the scheduling cell does not belong to the first cell set and / or the second cell set, the reference cell is not the scheduling cell).

[0103] The following embodiments will respectively illustrate the above three situations.

[0104] As mentioned above, in order to save power consumption of the terminal device, the cell can be indicated as deactivated or dormant. It should be noted that the following indications as dormant and / or deactivated include: the cell is indicated as deactivated, and when deactivated, it cannot be indicated as dormant, and when activated, it can be indicated as dormant. For the convenience of explanation, some configurations and indications related to deactivation or dormancy are first explained below. For a cell (for example, a Scell, but not limited to this), its corresponding serving cell configuration information may include or not include the fifth high-level parameter (egDormantBWP-Config-r16, or dormantBWP-Id), which is used to configure the dormant BWP (or, for configuring the dormant BWP ID) (for example, it indicates the ID of the BWP in the cell that serves as the dormant BWP), and / or Or the sixth high-level parameter (egfirstWithinActiveTimeBWP-Id-r16), used to configure the ID of the BWP to be activated when a DCI indication for SCell dormancy is received within the activation time (the DCI indicates that the terminal device uses a non-dormant BWP, for example, leaving Scell ​​dormancy), and / or the seventh high-level parameter (egdormancyGroupWithinActiveTime-r16), used to indicate the ID of the SCell group (or dormancy group) to which the cell belongs (for dormancy within the activation time), for example, it includes the fifteenth high-level parameter (egDormancyGroupID-r16) for configuring the dormancy group ID, and / or the ninth high-level parameter (egfirstOutsideActiveTimeBWP-Id-r16), used to configure the ID of the BWP to be activated when a DCI indication for SCell dormancy is not received within the activation time. In the following text, being configured with dormant BWP and / or sleep group ID means being configured / provided with the fifth high-level parameter and / or the sixth high-level parameter and / or the seventh high-level parameter and / or the ninth high-level parameter and / or the fifteenth high-level parameter (the serving cell configuration information includes / exists / provides the fifth high-level parameter and / or the sixth high-level parameter and / or the seventh high-level parameter and / or the ninth high-level parameter and / or the fifteenth high-level parameter).

[0105] In some embodiments, a cell is dormant, that is, the cell is in a dormant state or has entered dormancy, including: the activated downlink BWP (active DL BWP) of the cell is a dormant BWP (dormant BWP) (and the cell is an activated cell (activated Scell)). A cell that may be dormant includes: a cell configured with a dormant BWP and / or a dormant group ID, but is not limited thereto. Being indicated as dormant includes: being indicated as dormant by DCI. For example, being indicated as dormant by DCI format 1_1 or 0_1 or 1_3 or 0_3, for example, being indicated as dormant by the fifth information field (Scell ​​dormancy indication) and / or one or more first information fields of the above-mentioned DCI format. The specific indication method includes per Scell ​​group or per Scell ​​indication, but is not limited thereto.

[0106] For example, for the indication per Scell ​​group, the fifth information field includes a first bitmap, each bit in the first bitmap corresponds to a Scell ​​group and / or a sleep group ID, and the MSB to LSB of the fifth information field or the first bitmap correspond to the first to last Scell ​​groups in ascending order of the sleep group IDs. The above-mentioned Scell ​​group is identified by a sleep group ID. When the value of a bit in the first bitmap is 0, the UE for each activated SCell in the corresponding configured SCell group is instructed to activate the DL BWP (provided by the fifth higher-layer parameter); when the value of a bit in the first bitmap is 1, when the currently activated DL BWP is the sleep DL BWP, the UE for each activated SCell in the corresponding configured SCell group is instructed to activate the DL BWP (provided by the sixth higher-layer parameter); when the currently activated DL BWP is not the sleep DL BWP, the UE for each activated SCell in the corresponding configured SCell group is instructed to currently activate the DL BWP. The terminal device sets the activated DL BWP to the indicated activated DL BWP.

[0107] For example, for per-Scell ​​indication, the fifth information field and / or the one or more first information fields include / provide a second bitmap, where each bit in the second bitmap corresponds to a Scell. The MSB to LSB of the fifth information field and / or the other one or more information fields or the second bitmap correspond to Scells with the lowest to highest Scell ​​index in ascending order of Scell ​​index. The Scells corresponding to the second bitmap include Scells configured with a dormancy BWP and / or a sleep group ID, and / or Scells not configured with a dormancy BWP and / or a sleep group ID. The number of bits included in the second bitmap is determined by the number of Scells, which refers to the number of Scells configured with a dormancy BWP and / or a sleep group ID (only Scells configured with a dormancy BWP and / or a sleep group ID are counted), or the number of configured Scells (both Scells are counted regardless of whether a Scell ​​is configured with a dormancy BWP and / or a sleep group ID). The second bitmap is composed of / provides some or all of the bits in the fifth information field and / or each of the one or more first information fields. For example, (if the first DCI format and / or the second DCI format includes the fourth information field and / or the cell scheduled by the DCI is configured by a higher-layer parameter,) if all bits in one or more information blocks in the FDRA field are set to the above-mentioned specific value, then all or some of the bits in the corresponding / same-numbered information blocks in the one or more first information fields (or the information blocks corresponding to the one information block in the FDRA field) are used to provide the second bitmap (the other information blocks are used to schedule PDSCH / PUSCH on the corresponding cell) (that is, the FDRA field is also used to indicate which information blocks in the other information fields are used to indicate Scell ​​dormancy or provide the second bitmap). For example, the bits in each information field are used as the bits from the MSB to the LSB in the second bitmap, in descending order according to their positions in the information fields (or the order in which they are listed) and / or the positions of these information fields in the corresponding DCI format (or the order in which they are listed).For example, it includes, in sequence, {MSB to LSB of the first information block for providing the second bitmap in the MCS domain of TB1, MSB to LSB of the first information block for providing the second bitmap in the NDI domain of TB1, MSB to LSB of the first information block for providing the second bitmap in the RV domain of TB1, MSB to LSB of the first information block for providing the second bitmap in the HARQ process number domain, MSB to LSB of the second information block for providing the second bitmap in the MCS domain of TB1, MSB to LSB of the second information block for providing the second bitmap in the NDI domain of TB1, MSB to LSB of the second information block for providing the second bitmap in the RV domain of TB1, MSB to LSB of the second information block for providing the second bitmap in the HARQ process number domain, (and so on)}. For another example, it includes in sequence {MSB to LSB of the first information block for providing the second bitmap in the MCS domain of TB1, MSB to LSB of the second information block for providing the second bitmap in the MCS domain of TB1,… (and so on), MSB to LSB of the first information block for providing the second bitmap in the NDI domain of TB1, MSB to LSB of the second information block for providing the second bitmap in the NDI domain of TB1,… (and so on), MSB to LSB of the first information block for providing the second bitmap in the RV domain of TB1, MSB to LSB of the second information block for providing the second bitmap in the RV domain of TB1,… (and so on), MSB to LSB of the first information block for providing the second bitmap in the HARQ process number domain, MSB to LSB of the second information block for providing the second bitmap in the HARQ process number domain,… (and so on)}. When the value of one bit of the second bitmap is 0, for the UE corresponding to the activated SCell, the activation DL BWP (provided by the fifth high-level parameter) is indicated; when the value of one bit of the second bitmap is 1, when the currently activated DL BWP is a dormant DL BWP, for the UE corresponding to the activated SCell, the activation DL BWP (provided by the sixth high-level parameter) is indicated; when the currently activated DL BWP is not a dormant DL BWP, for the UE corresponding to the activated SCell, the currently activated DL BWP is indicated. The terminal device sets the activated DL BWP to the indicated activated DL BWP.

[0108] In the above embodiment, the one or more first information fields include one or more of a modulation and coding scheme, a new data indicator, a redundancy version, a HARQ process number, an antenna port, and a DMRS sequence initialization. In addition, the one or more first information fields may include, but are not limited to, at least one of the following information fields: for the first DCI format: an identifier for DCI formats, a BWP indicator, a time domain resource assignment, a virtual resource block-physical resource block mapping (VRB-to-PRB mapping), a physical resource block bundling size indicator, a rate matching indicator, a ZP CSI-RS trigger, a downlink assignment index, a TPC command for scheduled PUCCH, and a PUCCH resource indicator. indicator), HARQ feedback timing indicator (PDSCH-to-HARQ_feedback timing indicator), HARQ-ACK retransmission indicator (HARQ-ACK retransmission indicator), Transmission configuration indication (Transmission configuration indication), SRS request (SRS request), SRS offset indicator (SRS offset indicator), Priority indicator (Priority indicator), Channel Access-CPext, Minimum applicable scheduling offset indicator (Minimum applicable scheduling offset indicator), PDCCH monitoring adaptation indication (PDCCH monitoring adaptation indication), PUCCH Cell indicator (PUCCH Cell indicator),For the second DCI format: DCI format identifier, Bandwidth part indicator, Time domain resource assignment, Frequency hopping flag, TPC command for scheduled PUCCH, SRS resource indicator, Precoding information and number of layers, SRS request, SRS offset indicator, CSI request, PTRS-DMRS association, UL-SCH indicator, Open-loop power control parameter set indication, Priority indicator, Channel Access-CPext, Minimum applicable scheduling offset indicator, PDCCH monitoring adaptation indication. Examples are not given here one by one.

[0109] In some embodiments, the cell is deactivated, that is, the cell is in a deactivated state, and the cell is indicated as activated or deactivated or activated or deactivated in the following ways: receiving SCell activation / deactivation MAC CE (SCell Activation / Deactivation MAC CE) or enhanced SCell activation / deactivation MAC CE (Enhanced SCell Activation / Deactivation MAC CE), and according to the corresponding indication for the cell, the cell is activated or deactivated; or the SCell deactivation timer of the cell expires, and the cell is deactivated); or when the cell is configured with sCellState (activated) during Scell ​​configuration (that is, when the cell is initially configured or when the cell is added), the cell is activated, otherwise the cell is deactivated; or receiving SCG-state, the SCell of the SCG is deactivated, and if the cell belongs to the SCG, the cell is deactivated.

[0110] When the cell is activated, the DL BWP configured / provided by the tenth higher layer parameter (firstActiveDownlinkBWP-Id) and the UL BWP configured / provided by the sixteenth higher layer parameter (firstActiveUplinkBWP-Id) are activated.

[0111] In some embodiments, the cell that may be dormant and / or deactivated may only be an Scell, but the present application is not limited thereto.

[0112] In some embodiments, the terminal device does not need to monitor the PDCCH in the cell (Scell) or the dormant BWP on the dormant BWP, nor does it need to monitor the PDCCH for the cell (Scell) or the dormant BWP. At the same time, the terminal device does not receive or send some other channels or signals on the dormant BWP, such as PDSCH / DL-SCH, SRS, PUSCH / UL-SCH, CG-PUSCH, RACH, PUCCH, etc., but if configured, the terminal continues (according to the configuration) to perform channel state information (CSI) measurement, automatic gain control (AGC) and beam management, such as performing beam failure detection for the Scell ​​and performing beam failure recovery when beam failure is detected.

[0113] In some embodiments, when a cell is deactivated, the terminal device does not receive the cell PDSCH or PDCCH, and does not perform uplink transmissions or CQI measurements. When a cell is activated, the terminal device will receive PDSCH and PDCCH (if the UE is configured to monitor PDCCH in / from the cell) and expects to be able to perform CQI measurements. The network equipment (NG-RAN) ensures that when the PUCCH SCell (the secondary cell Scell ​​equipped with PUCCH) is deactivated, the SCells of the secondary PUCCH group (whose PUCCH signaling is associated with the PUCCH on the PUCCH SCell) are not activated. The network equipment (NG-RAN) ensures that the SCells mapped to the PUCCH SCell are deactivated before changing or deleting the PUCCH SCell. When the serving cell set is reconfigured, the SCells newly added to the set are initially activated or deactivated (according to the configuration of sCellState described above), and the SCells remaining in the set (not changed or reconfigured) do not change their activation state.

[0114] In some embodiments, the scheduling cell may be a cell that may be dormant and / or deactivated. Alternatively, it may not be (should not be) a cell that may be dormant and / or deactivated, or in other words, the terminal device does not expect the scheduling cell to be a cell that may be dormant and / or deactivated (a cell that may be dormant and / or deactivated cannot (be expected to be) a scheduling cell), for example, the terminal device does not expect the scheduling cell to be configured with a dormant BWP and / or dormant group ID.

For example, the terminal device does not expect the reference cell to be configured with a dormant BWP and / or a dormant group ID. In other words, the reference cell is not (should) be configured with a dormant BWP and / or a dormant group ID. Alternatively, the terminal device does not expect (corresponding to) the reference cell of the first cell set and / or the second cell set to be a cell that may be dormant and / or deactivated (a cell that may be dormant and / or deactivated is not (expected to be) a reference cell of the first cell set and / or the second cell set).

[0116] In some embodiments, the terminal device does not expect the first cell set and / or the second cell set to include cells that may be dormant and / or deactivated (cells that may be dormant and / or deactivated are not (expected to be) cells in the first cell set and / or the second cell set). In other words, the network device (NR-RAN) ensures that the first cell set and / or the second cell set do not include cells that may be dormant and / or deactivated. In other words, the cells in the first cell set and / or the second cell set are not (should not) be cells that may be dormant and / or deactivated.

[0119] In some embodiments, the terminal device does not expect (all or part of) the cells in the first cell set and / or the second cell set to be indicated as dormant and / or deactivated (the cells indicated as dormant and / or deactivated are not (expected to be) cells in the first cell set and / or the second cell set). In other words, the network device (NR-RAN) ensures that (all or part of) the cells in the first cell set and / or the second cell set are not indicated as dormant and / or deactivated.

[0120] In some embodiments, if the scheduling cell does not belong to the first cell set and / or the second cell set, the reference cell cannot (should not) be indicated as dormant and / or deactivated, or in other words, the terminal device does not expect the reference cell to be indicated as dormant and / or deactivated (the cell indicated as dormant and / or deactivated is not (expected to be) the reference cell).

Alternatively, the reference cell of ((corresponding to)) the first cell set and / or the second cell set is not dormant and / or deactivated.

[0123] In some embodiments, if a cell in the first cell set and / or the second cell set is dormant and / or deactivated, the terminal device does not expect the first DCI format and / or the second DCI format to schedule the cell or schedule a cell combination including the cell (the cell or the cell combination including the cell is (expected) not to be scheduled by the first DCI format and / or the second DCI format). In other words, the network device (NR-RAN) ensures that the first DCI format and / or the second DCI format does not schedule the cell or the cell combination including the cell.

[0124] The following describes monitoring and reception of the first DCI format and / or the second DCI format and the PDCCH carrying the DCI format when the scheduling cell and / or the reference cell are in a state related to deactivation and / or dormancy.

[0125] In some embodiments, (if) the scheduling cell and / or (corresponding to) the reference cell of the first cell set and / or the second cell set and / or (all or part of) the cells of the first cell set are dormant and / or deactivated, and / or (all or part of) the cells of the second cell set are dormant and / or deactivated; the terminal device does not listen to and / or receive the first DCI format, and / or does not listen to and / or receive the second DCI format.

[0126] In some embodiments, when (the terminal device expects) the scheduling cell and / or the reference cell of the first cell set and / or the second cell set is dormant and / or deactivated, the cells in the first cell set and / or the second cell set (which cannot be scheduled by other cells) are not (should not) activated and are not dormant. The network device (NR-RAN) ensures that when the scheduling cell and / or the reference cell of the first cell set and / or the second cell set is dormant and / or deactivated, the cells in the first cell set and / or the second cell set (which cannot be scheduled by other cells) are not (should not) activated and are not dormant.

[0127] In some implementations, (the terminal device expects) the scheduling cell and / or the reference cell of the first cell set and / or the second cell set is not configured with an Scell ​​deactivation timer (sCellDeactivationTimer), or, the network device (NR-RAN) ensures that the scheduling cell and / or the reference cell of the first cell set and / or the second cell set is not configured with an Scell ​​deactivation timer (sCellDeactivationTimer), or, the scheduling cell and / or the reference cell of the first cell set and / or the second cell set is configured with an Scell ​​deactivation timer of infinity, that is, timer-based SCell deactivation is disabled, and SCell deactivation cannot be controlled based on the timer.

[0128] In some implementations, the scheduling cell and / or (corresponding to) the reference cell of the first cell set and / or the second cell set and / or (all or part of) the cells in the first cell set are activated and not dormant, and / or (all or part of) the cells in the second cell set are activated and not dormant; the terminal device listens to and / or receives the first DCI format, and / or the receiver listens to and / or receives the second DCI format.

[0129] In some embodiments, (if) the scheduling cell belongs to the first cell set and / or the second cell set, and the terminal device is only provided with a search space set (search space sets) for the PDCCH candidates (or corresponding to the first DCI format and / or the second DCI format) on the scheduling cell, the reference cell is the scheduling cell, and the terminal device counts the sizes (sizes) of the first DCI format and / or the second DCI format and / or the PDCCH candidates (candidates) and / or the corresponding non-overlapping control channel elements (non-overlapping CCEs) for detecting the first DCI format and / or the second DCI format based on the reference cell.

[0130] In some embodiments, (if) (the scheduling cell does not belong to the first cell set and / or the second cell set), the terminal device is provided with search space sets with the same search space identifier (searchSpaceId) for the first DCI format and / or the second DCI format on the scheduling cell and a serving cell in the first cell set and / or the second cell set, the reference cell is the one cell, and the terminal device counts the size (sizes) of the first DCI format and / or the second DCI format and / or the PDCCH candidates (candidates) and / or the corresponding non-overlapping control channel elements (non-overlapping CCEs) for detecting the first DCI format and / or the second DCI format based on the reference cell (the sizes and / or PDCCH candidates and / or non-overlapping CCEs corresponding to the first DCI format and / or the second DCI format are recorded on the reference cell).

[0131] In some implementations, (if) the scheduling cell belongs to or does not belong to the first cell set and / or the second cell set, and / or the scheduling cell is different from the reference cell of the first cell set, and the scheduling cell is (activated and) not dormant, (if) the (corresponding) reference cell of the first cell set and / or the second cell set is dormant, the terminal device counts the sizes of the first DCI format and / or the second DCI format and / or the PDCCH candidates and / or the corresponding non-overlapping CCEs for detecting the first DCI format and / or the second DCI format based on the scheduling cell (the sizes and / or PDCCH candidates and / or non-overlapping CCEs corresponding to the first DCI format and / or the second DCI format are recorded on the scheduling cell).

[0132] The following examples illustrate this.

[0133] In some embodiments, if the scheduling cell and the reference cell are (both) dormant and / or deactivated, the UE does not monitor and / or receive the first DCI format and / or the second DCI format (in the scheduling cell).

[0134] In some embodiments, if the scheduling cell or the reference cell is dormant and / or deactivated, the UE does not monitor and / or receive the first DCI format and / or the second DCI format (in the scheduling cell).

[0135] In some embodiments, if the scheduling cell or the reference cell is (activated and) not dormant, the UE (in the scheduling cell) monitors and / or receives the first DCI format and / or the second DCI format.

[0136] In some embodiments, if all cells in the first cell set and / or the second cell set are dormant and / or deactivated, the UE does not monitor and / or receive the first DCI format and / or the second DCI format (in the scheduling cell).

[0137] In some embodiments, if at least one cell in the first cell set and / or the second cell set is (activated and) not dormant, (and the scheduling cell and / or the reference cell is (activated and) not dormant), the UE (in the scheduling cell) monitors and / or receives the first DCI format and / or the second DCI format, and the sizes and / or PDCCH candidates and / or non-overlapping CCEs (the count) corresponding to the first DCI format and / or the second DCI format are recorded on the reference cell, or the sizes and / or PDCCH candidates and / or non-overlapping CCEs (the count) corresponding to the first DCI format and / or the second DCI format are recorded on the scheduling cell (or, the UE assumes that the scheduling cell is the reference cell).

[0138] In some embodiments, if the reference cell is (activated and) not dormant, and the scheduling cell is dormant and / or deactivated, the UE monitors and / or receives the first DCI format and / or the second DCI format, and records the sizes and / or PDCCH candidates and / or non-overlapping CCEs (counts) corresponding to the first DCI format and / or the second DCI format on the reference cell.

[0139] In some embodiments, if the scheduling cell is (activated and) not dormant, and the reference cell is dormant and / or deactivated, the UE monitors and / or receives the first DCI format and / or the second DCI format, and records the sizes and / or PDCCH candidates and / or non-overlapping CCEs (counts) corresponding to the first DCI format and / or the second DCI format on the reference cell, or records the sizes and / or PDCCH candidates and / or non-overlapping CCEs corresponding to the first DCI format and / or the second DCI format on the scheduling cell (or, in other words, the UE assumes that the scheduling cell is the reference cell at this time).

[0140] In some embodiments, if the scheduling cell belongs to the first cell set and / or the second cell set, the reference cell is the scheduling cell, and the cell is dormant and / or deactivated, the UE does not monitor and / or receive the first DCI format and / or the second DCI format (in the scheduling cell). In other words, if the reference cell is the scheduling cell and the cell is dormant and / or deactivated, the UE does not monitor and / or receive the first DCI format and / or the second DCI format for scheduling (cells in) the first cell set and / or the second cell set.

[0141] In some embodiments, if the scheduling cell belongs to the first cell set and / or the second cell set, the reference cell is not the scheduling cell, and both the reference cell and the scheduling cell are dormant and / or deactivated, the UE does not monitor and / or receive the first DCI format and / or the second DCI format (in the scheduling cell).

[0142] In some embodiments, if the scheduling cell belongs to the first cell set and / or the second cell set, the reference cell is not the scheduling cell (the scheduling cell is dormant or not dormant), and the reference cell is (activated and) not dormant, the UE monitors and / or receives the first DCI format and / or the second DCI format, and records the sizes and / or PDCCH candidates and / or non-overlapping CCEs (count) corresponding to the first DCI format and / or the second DCI format on the reference cell.

[0143] In some embodiments, if the scheduling cell belongs to the first cell set and / or the second cell set, the reference cell is not the scheduling cell, the scheduling cell is dormant and / or deactivated, and the reference cell is (activated and) not dormant, the UE monitors and / or receives the first DCI format and / or the second DCI format, and records the sizes and / or PDCCH candidates and / or non-overlapping CCEs (count) corresponding to the first DCI format and / or the second DCI format on the reference cell.

[0144] In some embodiments, if the scheduling cell belongs to the first cell set and / or the second cell set, the reference cell is not the scheduling cell (the reference cell is dormant and / or deactivated or is (activated and) not dormant), and the scheduling cell is (activated and) not dormant, the UE monitors and / or receives the first DCI format and / or the second DCI format, and records the sizes and / or PDCCH candidates and / or non-overlapping CCEs (count) corresponding to the first DCI format and / or the second DCI format on the reference cell.

[0145] In some embodiments, if the scheduling cell belongs to the first cell set and / or the second cell set, the reference cell is not the scheduling cell, the reference cell is dormant and / or deactivated, (and the scheduling cell is (activated and) not dormant) the UE monitors and / or receives the first DCI format and / or the second DCI format, and records the sizes and / or PDCCH candidates and / or non-overlapping CCEs (count) corresponding to the first DCI format and / or the second DCI format on the scheduling cell (or, the UE assumes that the scheduling cell is the reference cell).

[0146] In some embodiments, if the scheduling cell does not belong to the first cell set and / or the second cell set, the reference cell is dormant and / or deactivated (and the scheduling cell is dormant and / or deactivated), the UE does not (in the scheduling cell) monitor and / or receive the first DCI format and / or the second DCI format.

[0147] In some embodiments, if the scheduling cell does not belong to the first cell set and / or the second cell set (the scheduling cell is dormant and / or deactivated or (activated and) not dormant), and the reference cell is (activated and) not dormant, the UE monitors and / or receives the first DCI format and / or the second DCI format, and records the sizes and / or PDCCH candidates and / or non-overlapping CCEs (count) corresponding to the first DCI format and / or the second DCI format on the reference cell.

[0148] In some embodiments, if the scheduling cell does not belong to the first cell set and / or the second cell set, the scheduling cell is dormant and / or deactivated, and the reference cell is (activated and) not dormant, the UE monitors and / or receives the first DCI format and / or the second DCI format, and records the sizes and / or PDCCH candidates and / or non-overlapping CCEs (count) corresponding to the first DCI format and / or the second DCI format on the reference cell.

[0149] In some embodiments, if the scheduling cell does not belong to the first cell set and / or the second cell set (the reference cell is dormant and / or deactivated or (activated and) not dormant), and the scheduling cell is (activated and) not dormant, the UE monitors and / or receives the first DCI format and / or the second DCI format, and records the sizes and / or PDCCH candidates and / or non-overlapping CCEs (count) corresponding to the first DCI format and / or the second DCI format on the reference cell.

[0150] In some embodiments, if the scheduling cell does not belong to the first cell set and / or the second cell set, the reference cell is dormant and / or deactivated, and the scheduling cell is (activated and) not dormant, the UE monitors and / or receives the first DCI format and / or the second DCI format, and records the sizes and / or PDCCH candidates and / or non-overlapping CCEs (count) corresponding to the first DCI format and / or the second DCI format on the scheduling cell.

[0151] In some embodiments, if the reference cell is not a scheduling cell, the reference cell is dormant and / or deactivated (the scheduling cell is (activated and) not dormant (the scheduling cell belongs to or does not belong to the first cell set and / or the second cell set), the UE monitors and / or receives the first DCI format and / or the second DCI format, and records the sizes and / or PDCCH candidates and / or non-overlapping CCEs corresponding to the first DCI format and / or the second DCI format in the scheduling cell.

[0152] The following describes the scheduling of dormant and / or deactivated cells.

[0153] In some embodiments, the first cell set and / or the second cell set may include cells that may be dormant and / or deactivated. Alternatively, the first cell set and / or the second cell set may not / should not include cells that may be dormant and / or deactivated.

[0154] In some embodiments, if the first cell set and / or the second cell set include cells that may be dormant and / or deactivated, the cells that may be dormant and / or deactivated may be indicated as dormant and / or deactivated by the first DCI format and / or the second DCI format used to schedule cells in the first cell set and / or the second cell set, or may be indicated as dormant and / or deactivated by other DCI formats or other first DCI formats and / or second DCI formats (used to schedule cells in other cell sets (different cell set identifiers)). Alternatively, the cells that may be dormant and / or deactivated may not be indicated as dormant and / or deactivated by the first DCI format and / or the second DCI format used to schedule cells in the first cell set and / or the second cell set, and may be indicated as dormant and / or deactivated by other DCI formats or other first DCI formats and / or second DCI formats (used to schedule cells in other cell sets (different cell set identifiers)). Alternatively, the cell that may be dormant and / or deactivated may not be indicated as dormant and / or deactivated (or in other words, the UE does not expect the cell to be (indicated as) dormant and / or deactivated).

[0155] In some embodiments, if the first cell set and / or the second cell set include dormant and / or deactivated cells, the dormant and / or deactivated cells may be used for scheduling the first DCI format and / or second DCI format scheduling of cells in the first cell set and / or the second cell set. Alternatively, the cell may not be used for scheduling the first DCI format and / or second DCI format scheduling of cells in the first cell set and / or the second cell set (including: the UE does not expect the scheduled cells to include dormant and / or deactivated cells). In other words, for the received first DCI format and / or second DCI format, the scheduled cells may include dormant and / or deactivated cells (including cells indicated as dormant and / or deactivated by the first DCI format and / or second DCI format or another DCI). Alternatively, the scheduled cells may not / should include dormant and / or deactivated cells (including: the UE does not expect the scheduled cells to include dormant and / or deactivated cells).

[0156] In some embodiments, (if) the first cell set and / or the second cell set includes dormant cells and / or deactivated cells, the UE does not determine the sizes of the first DCI format and / or the second DCI format based on the dormant cells and / or deactivated cells.

[0157] For example, if the first cell set and / or the second cell set include dormant cells, the UE does not determine the number of information bits in the first DCI format and / or the second DCI format based on the dormant cells. For example, for the first DCI format, if a third higher-layer parameter is configured, the size of the first DCI format is determined by the configuration of the corresponding (DL) BWP of the (scheduled) cell in the entry in the third higher-layer parameter that can result in the largest size. If the third higher-layer parameter is not configured, the size of the first DCI format is determined by the configuration of the corresponding (DL) BWP of the cells in the first cell set and / or the second cell set. Wherein, dormant cells are excluded from the above-mentioned entries or the first cell set and / or the second cell set. Similarly, for the second DCI format, if a fourth higher-layer parameter is configured, the size of the second DCI format is determined by the configuration of the corresponding (UL) BWP of the (scheduled) cell in the entry in the fourth higher-layer parameter that can result in the largest size. If the fourth higher layer parameter is not configured, the size of the second DCI format is determined by the configuration of the corresponding (UL) BWP of (all) cells in the cell set. Wherein, for dormant cells, they are excluded from the above entries or the first cell set and / or the second cell set.

[0158] In some embodiments, (if) the first cell set and / or the second cell set includes dormant cells and / or deactivated cells, the UE determines the sizes (number of information bits) of the first DCI format and / or the second DCI format based on the activated (DL / UL)BWP and / or dormant (DL)BWP for the dormant cells and / or the (DL)BWP configured / provided by the sixth higher layer parameter and / or the (DL)BWP configured / provided by the ninth higher layer parameter and / or the BWP configured / provided by the tenth higher layer parameter and / or the BWP configured / provided by the sixteenth higher layer parameter, and / or based on the (DL)BWP configured / provided by the tenth higher layer parameter for the deactivated cells and / or the (UL)BWP configured / provided by the sixteenth higher layer parameter and / or the BWP configured / provided by the sixth higher layer parameter and / or the BWP configured / provided by the ninth higher layer parameter. For example, the UE determines the sizes (number of information bits) of the first DCI format based on the aforementioned configured / provided DL BWP, and determines the sizes (number of information bits) of the second DCI format based on the aforementioned configured / provided UL BWP. However, the embodiment of the present application is not limited to this, and the sizes (number of information bits) of the first DCI format may also be determined based on the aforementioned configured / provided UL BWP, and the sizes (number of information bits) of the second DCI format may be determined based on the aforementioned configured / provided DL BWP.

[0159] For example, if the sixth higher-layer parameter is provided, the size of the DCI format is determined based on the BWP configured / provided by the sixth higher-layer parameter; otherwise, it is determined based on the BWP configured / provided by the ninth higher-layer parameter. However, the present invention is not limited thereto. For example, if the third higher-layer parameter is configured for the first DCI format, the size of the first DCI format is determined by the configuration of the corresponding (DL) BWP of the (scheduled) cell in the entry that can result in the largest size (largest size) among the entries in the third higher-layer parameter. If the third higher-layer parameter is not configured, the size of the first DCI format is determined by the configuration of the corresponding (DL) BWP of (all) cells in the cell set. For a dormant cell, its corresponding BWP is the activated (DL) BWP and / or the dormant BWP and / or the (DL) BWP configured / provided by the sixth higher-layer parameter and / or the (DL) BWP configured / provided by the ninth higher-layer parameter. Similarly, for the second DCI format, if the fourth higher layer parameter is configured, the size of the second DCI format is determined by the configuration of the corresponding (UL) BWP of the (scheduled) cell in the entry in the fourth higher layer parameter that can result in the maximum size. If the fourth higher layer parameter is not configured, the size of the second DCI format is determined by the configuration of the corresponding (UL) BWP of (all) cells in the cell set. For a dormant cell, its corresponding (UL) BWP is the activated (UL) BWP.

[0160] In some embodiments, the size of a DCI format is the number of information bits included in the DCI format, or vice versa.

[0161] For example, a cell that may be deactivated may also be a cell that may be dormant, and the BWP configured / provided by the tenth high-level parameter is or is not a dormant BWP. If the BWP configured / provided by the tenth high-level parameter is not a dormant BWP, the size of the sizes of the first DCI format is determined based on the BWP configured / provided by the tenth high-level parameter; otherwise, the size of the first DCI format is determined based on the BWP configured / provided by the sixth high-level parameter and / or the BWP configured / provided by the ninth high-level parameter.

[0162] For example, a cell that may be deactivated may also be a cell that may be dormant, and the BWP configured / provided by the sixteenth high-level parameter is or is not a dormant BWP. If the BWP configured / provided by the sixteenth high-level parameter is not a dormant BWP, the size of the sizes of the second DCI format is determined based on the BWP configured / provided by the sixteenth high-level parameter; otherwise, the size of the sizes of the second DCI format is determined based on the BWP configured / provided by the sixth high-level parameter and / or the BWP configured / provided by the ninth high-level parameter.

[0163] For example, for the first DCI format, in the scheduled cell set, if the SCell is deactivated and the tenth high-level parameter does not set the dormant BWP, the terminal device determines the number of information bits of the first DCI format based on the DL BWP provided by the tenth high-level parameter of the SCell; if the activated DL BWP of the SCell is the dormant DL BWP, or the SCell is deactivated and the tenth high-level parameter sets the dormant BWP, if the sixth high-level parameter provides the DL BWP, the terminal device determines the number of information bits of the first DCI format based on the DL BWP provided by the sixth high-level parameter of the SCell, otherwise (i.e., if the sixth high-level parameter is not provided for the SCell), the terminal device determines the number of information bits of the first DCI format based on the DL BWP provided by the ninth high-level parameter.

[0164] For example, for the second DCI format, in the scheduled cell set, if the SCell is deactivated and the tenth high-level parameter does not set the dormant BWP, the terminal device determines the number of information bits of the second DCI format based on the DL BWP provided by the tenth high-level parameter of the SCell; if the activated DL BWP of the SCell is the dormant DL BWP, or the SCell is deactivated and the tenth high-level parameter sets the dormant BWP, if the sixth high-level parameter provides the DL BWP, the terminal device determines the number of information bits of the second DCI format based on the DL BWP provided by the sixth high-level parameter of the SCell, otherwise (i.e., if the sixth high-level parameter is not provided for the SCell), the terminal device determines the number of information bits of the second DCI format based on the DL BWP provided by the ninth high-level parameter.

[0165] For example, for the second DCI format, in the scheduled cell set, if the SCell is deactivated, the terminal device determines the number of information bits in the second DCI format based on the UL BWP provided by the sixteenth high-level parameter; if the active DL BWP of an SCell is a dormant DL BWP, the terminal device determines the number of information bits in the second DCI format based on the activated UL BWP. If the active DL BWP of an SCell is a dormant DL BWP, the UE determines the number of information bits in DCI format 0_3 (carried by PDCCH on the scheduling cell)based on the active UL BWP

[0166] In some embodiments, (if) the first cell set and / or the second cell set includes dormant cells and / or deactivated cells, and / or the cells scheduled by the first DCI format and / or the second DCI format include dormant cells and / or deactivated cells, the UE determines the sizes of the information block corresponding to the dormant cell and / or the deactivated cell in the first part of the first information field in the first DCI format and / or the second DCI format based on the activated (DL / UL)BWP and / or dormant (DL)BWP for the dormant cell and / or the (DL)BWP configured / provided by the sixth higher layer parameter and / or the (DL)BWP configured / provided by the ninth higher layer parameter and / or the BWP configured / provided by the tenth higher layer parameter and / or the BWP configured / provided by the sixteenth higher layer parameter, and / or based on the BWP configured / provided by the tenth higher layer parameter for the deactivated cell and / or the (UL)BWP configured / provided by the sixteenth higher layer parameter and / or the BWP configured / provided by the sixth higher layer parameter and / or the BWP configured / provided by the ninth higher layer parameter. The first information field of the first part includes frequency domain resource assignment and / or PTRS-DMRS association and / or SRS resource indicator and / or precoding information and number of layers and / or antenna ports. For example, if the sixth higher-layer parameter is provided, the sizes of the information block are determined based on the BWP configured / provided by the sixth higher-layer parameter; otherwise, the sizes of the information block are determined based on the BWP configured / provided by the ninth higher-layer parameter. However, this is not limited to this.

[0167] In some embodiments, (if) the first cell set and / or the second cell set includes dormant cells and / or deactivated cells, the first DCI format and / or the second DCI format does not include dedicated information bits for the dormant cells and / or deactivated cells.

[0168] In some embodiments, (if) the first cell set and / or the second cell set includes dormant cells and / or deactivated cells, the first part of the first information field in the first DCI format and / or the second DCI format does not include an information block corresponding to the dormant cells and / or the deactivated cells. The above-mentioned one or more first part first information fields include Frequency domain resource assignment and / or PTRS-DMRS association and / or SRS resource indicator and / or Precoding information and number of layers and / or Antenna ports.

[0169] In some embodiments, (if) the first cell set and / or the second cell set include dormant cells and / or deactivated cells, and / or the cells scheduled by the first DCI format and / or the second DCI format include dormant cells and / or deactivated cells, the second part of the first information field in the first DCI format and / or the second DCI format is not applied or applied to the dormant cells and / or deactivated cells, and / or the processor of the terminal device ignores the scheduling information corresponding to the dormant cells. The second part of the first information field includes Bandwidth part indicator and / or Frequency hopping flag and / or Precoding information and number of layers and / or Antenna ports and / or CSI request and / or beta_offset indicator and / or DMRS sequence initialization and / or UL-SCH indicator and / or ChannelAccess-CPext-CAPC and / or Open-loop power control parameter set indication and / or Priority indicator and / or Minimum applicable scheduling offset indicator and / or PDCCH monitoring adaptation indication and / or ChannelAccess-CPext. For example, the Bandwidth part indicator is not applied to the dormant cell, and the terminal device does not switch the (activated) (DL and / or UL) BWP of the dormant cell according to the indication of the Bandwidth part indicator. Alternatively, the Bandwidth part indicator is applied to the dormant cell, and the terminal device switches the (activated) (DL and / or UL) BWP of the dormant cell according to the indication of the Bandwidth part indicator. Examples are not given one by one here. Examples are not given one by one here.

[0170] In some embodiments, (if) the first cell set and / or the second cell set include dormant cells and / or deactivated cells, and / or the cells scheduled by the first DCI format and / or the second DCI format include dormant cells and / or deactivated cells, the information blocks corresponding to the dormant cells and / or deactivated cells in the third part first information field in the first DCI format and / or the second DCI format are not applied to the dormant cells and / or deactivated cells, and / or the processor of the terminal device ignores the information blocks corresponding to the dormant cells and / or deactivated cells in the third part first information field in the first DCI format and / or the second DCI format. The third part first information field includes Frequency domain resource assignment and / or PTRS-DMRS association and / or Modulation and coding scheme and / or New data indicator and / or Redundancy version and / or HARQ process number and / or TPC command for scheduled PUSCH and / or SRS resource indicator and / or Precoding information and number of layers and / or Antenna ports. The information blocks of the first information field of the third part are placed in ascending order according to the serving cell index (of the scheduled cell set or cells in the scheduled cells).

[0171] For example, the Frequency domain resource assignment field includes one or more information blocks, the number of information blocks included is equal to the number of scheduled cells (indicated by the third information field or configured by the third high-level parameter and / or the fourth high-level parameter) or the number of cells in the scheduled cell set (indicated by the fourth information field or configured by the eleventh high-level parameter). The information blocks in the Frequency domain resource assignment field are placed in ascending order according to the serving cell index, where information block 1 corresponds to the cell with the smallest serving cell index (Frequency domain resource assignment). Alternatively, the number of information blocks included is equal to or less than the number of the above-mentioned scheduled cells or the number of cells in the scheduled cell set excluding dormant cells. If the cell corresponding to an information block in the Frequency domain resource assignment field is dormant, the UE ignores the information block.

[0172] In some embodiments, (if) the first cell set and / or the second cell set includes dormant cells and / or deactivated cells, and / or the cells scheduled by the first DCI format and / or the second DCI format include dormant cells and / or deactivated cells, the index corresponding to the dormant cells and / or deactivated cells in the entry indicated by the fourth part first information field in the first DCI format and / or the second DCI format is not applied to the dormant cells and / or deactivated cells, and / or the processor of the terminal device ignores the index corresponding to the dormant cells and / or deactivated cells in the entry indicated by the fourth part first information field in the first DCI format and / or the second DCI format. The fourth part first information field includes Time domain resource assignment and / or SRS request and / or SRS offset indicator and / or Rate matching indicator and / or ZP CSI-RS trigger and / or Transmission configuration indication. The indexes in the entry are placed in ascending order of the serving cell index (of the cells in the scheduled cell set).

[0173] In some embodiments, (if) the second cell set includes dormant cells and / or deactivated cells, and / or the cells scheduled by the second DCI format include dormant cells and / or deactivated cells, the CSI request and / or UL-SCH indicator in the second DCI format is applied to the cell with the smallest serving cell index among the cells scheduled by the first DCI format and / or the second DCI format, except the dormant cells and / or deactivated cells, and / or the UE sends a CSI report (according to the CSI request) on the PUSCH of the cell with the smallest serving cell index except the dormant cells and / or deactivated cells, and / or the UE sends UL-SCH or does not send UL-SCH on the PUSCH of the cell with the smallest serving cell index except the dormant cells and / or deactivated cells (according to the UL-SCH indicator).

[0174] In some embodiments, if the cell with the smallest serving cell index among the cells scheduled by the second DCI format is dormant or deactivated, the UE ignores the CSI request and / or UL-SCH indicator in the second DCI format.

[0175] In some embodiments, if the second DCI format includes a CSI request and / or a UL-SCH indicator, the UE does not expect the cells scheduled by the second DCI format to include dormant cells and / or deactivated cells, or the UE does not expect the cell with the smallest serving cell index among the cells scheduled by the second DCI format to be dormant or deactivated.

[0176] In some embodiments, (if) the cells scheduled by the first DCI format include dormant cells and / or deactivated cells, the UE does not receive PDSCH in the dormant cells and / or deactivated cells, and / or, (if) the cells scheduled by the second DCI format include dormant cells and / or deactivated cells, the UE does not send PUSCH in the dormant cells and / or deactivated cells.

[0177] The above types of first information fields are merely examples, and the embodiments of the present application are not limited thereto. For example, other types of first information fields in the above examples may also be included.

[0178] As previously described, the network device may use the first DCI format and / or the second DCI format to perform Scell ​​dormancy indication. The specific instructions are as previously described and will not be further described here. The terminal device informs the network device whether it supports Scell ​​dormancy indication using the first DCI format and / or the second DCI format. Details are described below.

[0179] In some embodiments, regarding capability reporting, the method may further include: the terminal device sends to the network device first capability information indicating that the terminal device supports a cell dormancy indication (Scell ​​dormancy indication) in a first DCI format (received on SPcell) and / or the terminal device supports a cell dormancy indication (Scell ​​dormancy indication) in a second DCI format (received on SPcell) (SCell dormancy indication received on SPCell with DCI format 0_3 / 1_3), and / or the terminal device supports a third capability information indicating that the terminal device supports a cell dormancy indication (Scell ​​dormancy indication) in a third DCI format (for example, DCI format 1_1) and / or a fourth DCI format (for example, DCI format 0_1) (received on SPcell).

[0180] In some embodiments, the first capability information and the second capability information are the same information or different information. For example, the first capability information and the second capability information are the same information: the information is used to indicate that the terminal device supports the cell dormancy indication (Scell ​​dormancy indication) of the third capability information (received on the SPcell).

[0181] In some embodiments, the first capability information and the second capability information are, for example, scellDormancyWithinActiveTime-r18, and the third capability information is, for example, scellDormancyWithinActiveTime-r16. If the third capability information indicates support, then for each carrier, the terminal device supports one dormant BWP and at least one non-dormant BWP. One dormant BWP and one non-dormant BWP are UE-specific BWPs.

[0182] In some embodiments, the first capability information includes (capability) information for indicating that the terminal device supports per Scell ​​cell dormancy indication (Scell ​​dormancy indication) in the above-mentioned first DCI format, and / or, (capability) information for indicating that the terminal device supports per Scell ​​cell dormancy indication (Scell ​​dormancy indication) in the above-mentioned first DCI format, and the second capability information includes (capability) information for indicating that the terminal device supports per Scell ​​cell dormancy indication (Scell ​​dormancy indication) in the above-mentioned second DCI format, and / or, (capability) information for indicating that the terminal device supports per Scell ​​cell dormancy indication (Scell ​​dormancy indication) in the above-mentioned second DCI format.

[0183] In some embodiments, a terminal device that supports the cell dormancy indication (Scell ​​dormancy indication) in the first DCI format or the second DCI format should also support the cell dormancy indication (Scell ​​dormancy indication) in the third DCI format or the fourth DCI format. For example, a terminal device that supports scellDormancyWithinActiveTime-r18 should also support scellDormancyWithinActiveTime-r16. Alternatively, without limitation thereto, a terminal device that supports the cell dormancy indication (Scell ​​dormancy indication) in the first DCI format or the second DCI format may not support the cell dormancy indication (Scell ​​dormancy indication) in the third DCI format or the fourth DCI format.

[0184] In some embodiments, if the terminal device supports cell dormancy indication in the third DCI format or the fourth DCI format, and / or the first DCI format or the second DCI format, then for each (DL) carrier, the terminal device supports one dormant BWP and at least one non-dormant BWP, respectively.

[0187] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0188] One of the beneficial effects of the embodiments of the present application is that, when a cell is deactivated and / or dormant, a terminal device monitors and / or receives, or does not monitor and / or receive, a DCI format supporting the scheduling of a PDSCH or PUSCH for multiple cells, as well as the PDSCH or PUSCH scheduled by the DCI format. This can achieve multi-carrier enhancement while saving power consumption of the terminal device and improving resource efficiency.
