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] Carrier aggregation technology allows the primary cell (Pcell) and the secondary cell (Scell) used for bandwidth expansion to simultaneously send data to terminal devices, thereby increasing system bandwidth and improving data rates. However, since data flows when users access the Internet are typically bursty and intermittent, even when the Scell ​​is not transmitting data, the terminal device must continuously monitor the Scell's control channel (such as the PDCCH), the PDCCH used to schedule the Scell ​​(for example, in cross-carrier scheduling), or transmit and receive other channels or signals (such as periodic or semi-continuous channels or signals), resulting in increased baseband power consumption for the terminal device. To this end, the SCell dormant state is introduced based on the SCell activation and deactivation states. That is, when there is no data transmission in the SCell, by configuring a dormant BWP in the SCell, the terminal device does not need to monitor the PDCCH in the SCell or the dormant BWP, nor does it need to monitor the PDCCH for the SCell or the dormant BWP. At the same time, the terminal device does not receive or transmit other channels or signals such as PDSCH / DL-SCH, SRS, PUSCH / UL-SCH, CG-PUSCH, RACH, PUCCH, etc. on the dormant BWP, thereby saving terminal device power consumption. At the same time, this function also supports switching between dormant BWP and non-dormant BWP through signaling instructions. When data transmission is available, it can quickly switch to the active state and quickly resume business.

[0007] In the Rel-18 release currently under discussion, to support scheduling multiple cells with a single DCI, new DCI formats will be introduced for scheduling PUSCH and PDSCH, respectively. Currently, it has been agreed that these DCI formats can also be used to indicate secondary cell dormancy, that is, to instruct the Scell ​​to switch between a dormant BWP and an active BWP. However, the standard currently does not define how to indicate secondary cell dormancy using these DCI formats (support).

[0008] 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.

[0009] According to one aspect of an embodiment of the present application, there is provided an information sending apparatus, applied to a network device, comprising:

[0011] A first DCI format and / or a second DCI format is sent in the first cell, wherein the first DCI format is used to schedule a PDSCH in a cell, or multiple PDSCHs in multiple cells and each cell corresponds to a PDSCH; the second DCI format is used to schedule a PUSCH in a first cell, or multiple PUSCHs in multiple cells and each cell corresponds to a PUSCH.

[0012] According to another aspect of an embodiment of the present application, there is provided an information receiving apparatus, applied to a terminal device, comprising:

[0013] a first receiving unit, configured to receive serving cell configuration information of a first cell, the serving cell configuration information including or excluding a ninth higher layer parameter for configuring a first DCI format to include a first information field for an Scell ​​dormancy indication, and / or the serving cell configuration information including or excluding a tenth higher layer parameter for configuring a second DCI format to include a first information field for an Scell ​​dormancy indication;

[0014] A first DCI format and / or a second DCI format is received in the first cell, wherein the first DCI format is used to schedule a PDSCH in a cell, or multiple PDSCHs in multiple cells and each cell corresponds to a PDSCH; and the second DCI format is used to schedule a PUSCH in a first cell, or multiple PUSCHs in multiple cells and each cell corresponds to a PUSCH.

[0015] 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.

[0016] One of the beneficial effects of the embodiments of the present application is that the DCI format that supports scheduling multiple cells through a single DCI can (support) indicate secondary cell dormancy (Scell ​​dormancy), and supports scheduling cells or scheduling cells at different times, which can save terminal device power consumption and improve resource efficiency while achieving multi-carrier enhancement.

[0049] 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.

[0050] Embodiments of the first aspect

[0051] An embodiment of the present application provides a method for receiving information, which is described from the perspective of a terminal device.

[0052] 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:

[0053] 201. Receive serving cell configuration information of a first cell, where the serving cell configuration information includes or does not include a ninth higher layer parameter for configuring a first DCI format to include a first information field for an Scell ​​dormancy indication, and / or the serving cell configuration information includes or does not include a tenth higher layer parameter for configuring a second DCI format to include a first information field for an Scell ​​dormancy indication.

[0054] 202. Receive a first DCI format and / or a second DCI format in the first cell, wherein the first DCI format is used for scheduling one PDSCH in one cell, or multiple PDSCHs in multiple cells with one PDSCH per cell; and the second DCI format is used for scheduling one PUSCH in one cell, or multiple PUSCHs in multiple cells with one PUSCH per cell.

[0055] 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.

[0056] 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, "DCI format" may be replaced by "DCI format," "DCI," or "DCI using a DCI format." The CRC of the first DCI format and / or the second DCI format is scrambled by the C-RNTI or MCS-C-RNTI.

[0057] In some embodiments, the terminal device may be configured to monitor / receive the first DCI format and / or the second DCI format on one or more cells, which are referred to as first cells, for example.

[0058] In some embodiments, the serving cell configuration information (ServingCellConfig) is used to configure (add or modify) a serving cell for a terminal device, which may be a SpCell (or primary cell, i.e., Pcell or PScell) or an SCell of an MCG or SCG. The serving cell configuration information of the first 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 first cell. For example, the eighth high-level parameter is included in the search space information (SearchSpace) in the serving cell configuration information. That is, whether the terminal device monitors DCI format 1_3 and / or DCI format 0_3 in the first cell is configured per SearchSpace. For example, for a UE-specific search space (i.e., USS) configured by a 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. The search space information is, for example, configured per BWP, that is, included in the BWP configuration information.

[0059] In some embodiments, the serving cell configuration information of the first 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 (egsetofCellsID) for configuring the cell set ID, including or excluding information for configuring the (scheduled) cell list for the first DCI format (ScheduledCell-ListDCI-1-3, first high-level parameter), including or excluding information for configuring the (scheduled) cell list for the second DCI format (ScheduledCell-ListDCI-0-3, second high-level parameter), including or excluding information for configuring the (scheduled) cell combination list for the first DCI format (scheduledCellCombo-ListDCI-1-3, third high-level parameter), including or excluding information for configuring the (scheduled) cell combination list for the second DCI format The information of the (scheduled) cell combination list in the format (scheduledCellCombo-ListDCI-0-3, the fourth high-level parameter) is included. The third high-level parameter and the fourth high-level parameter respectively include one or more fourteenth high-level parameters (egScheduledCellCombo) for configuring the cell combination (entry entry). The cell combination information can correspond to the first DCI format or the second DCI format, as shown in Figure 3.

[0060] 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.

[0061] In some embodiments, the first DCI format is used to schedule PDSCH(s) in one or more cells (in a first cell set), the second DCI format is used to schedule PUSCH(s) in one or more cells (in a second cell set), the first cell set is configured by a first higher-layer parameter (i.e., the first cell set includes cells in a cell list configured by the first higher-layer parameter), and the second cell set is configured by a second higher-layer parameter (i.e., the second cell set includes cells in a cell list configured by the second higher-layer parameter). Wherein, "used for scheduling" indicates that scheduling is supported or can be scheduled, can be actually scheduled, or is not actually scheduled.

[0062] In some embodiments, for a first cell (or in the serving cell configuration information of a first cell), up to four cell sets can be configured (one cell set includes a first cell set and / or a second cell set). That is, the eleventh higher-layer parameter includes up to four twelfth higher-layer parameters or entries. The value range of the cell set ID configured by the thirteenth higher-layer parameter is 0, 1, 2, 3 or 1, 2, 3, 4.

[0063] In some embodiments, a twelfth high-level parameter includes the first high-level parameter and / or the second high-level parameter. When the terminal device is configured to monitor the first DCI format in the first cell, the eleventh high-level parameter includes at least one twelfth high-level parameter including the first high-level parameter. When the terminal device is configured to monitor the second DCI format in the first cell, the eleventh high-level parameter includes at least one twelfth high-level parameter including the second high-level parameter.

[0064] In some embodiments, the first higher layer parameter and the second higher layer parameter respectively indicate the cell lists (or the first cell set and the second cell set) for the first DCI format and the second DCI format by indicating the serving cell index of the cell.

[0065] In some embodiments, a first cell set and a second cell set each include at most four cells. For example, the first higher layer parameter and the second higher layer parameter each indicate at least two and at most four (i.e., 2 to 4) serving cell indices. Thus, cells corresponding to the indicated serving cell indices belong to the first cell set and the second cell set, respectively.

[0066] In some embodiments, the cell sets (including the first cell set and / or the second cell set) configured by different twelfth higher layer parameters include (completely) different cells, ie, there is no intersection.

[0067] In some embodiments, the cells included in the first cell set and the second cell set in the same cell set (i.e., the first cell set configured with the first high-level parameter and the second cell set configured with the second high-level parameter in the same twelfth high-level parameter) are (completely) the same or (completely / partially) different.

[0068] In some embodiments, the first higher layer parameter and the second higher layer parameter indicate cells in ascending order of serving cell index, and / or the cells in the first cell set and the second cell set are respectively mapped to indices (eg 0, 1, 2, 3) in ascending order of serving cell index.

[0069] In some embodiments, one third higher layer parameter and one fourth higher layer parameter are respectively configured with at least two fourteenth higher layer parameters (or two entries).

[0070] In some embodiments, the cell combination list configured by the third higher layer parameter and / or the cell combination list for the first DCI format is, for example, referred to as a first cell combination list, and the cell combinations in the list (i.e., the cell combinations configured by the fourteenth higher layer parameter in the third higher layer parameter) are referred to as the first cell combination. The cell combination list configured by the fourth higher layer parameter and / or the cell combination list for the second DCI format is, for example, referred to as a second cell combination list, and the cell combinations in the list (i.e., the cell combinations configured by the fourteenth higher layer parameter in the fourth higher layer parameter) are referred to as the second cell combination.

[0071] In some embodiments, the fourteenth higher layer parameter indicates a cell included in the cell combination based on a second index of a cell in the corresponding first cell set or second cell set. For example, a fourteenth higher layer parameter included in the third higher layer parameter indicates a cell included in the first cell combination based on a second index of a cell in the first cell set configured by the first higher layer parameter in the same twelfth higher layer parameter. A fourteenth higher layer parameter included in the fourth higher layer parameter indicates a cell included in the second cell combination based on a second index of a cell in the second cell set configured by the second higher layer parameter in the same twelfth higher layer parameter.

[0072] In some embodiments, the first cell is a Pcell, a PScell, a primary cell, a SpCell, a PUCCH Scell, or a Scell. The first cell is a scheduling cell, configured to send a first DCI format and / or a second DCI format for scheduling the first cell and / or other cells.

[0073] In some embodiments, a Scell ​​is configured or not configured with a sleep BWP and / or a sleep group ID.

[0074] In some embodiments, a primary cell or a PUCCH Scell ​​is not configured with a sleep BWP and / or a sleep group ID, but is not limited thereto.

[0075] In some embodiments, for a cell (e.g., an Scell, but not limited thereto), its corresponding serving cell configuration information may include or exclude a fifth high-level parameter (e.g., DormantBWP-Config-r16, or dormantBWP-Id), used to configure a dormant BWP (or, to configure a dormant BWP ID) (e.g., indicating the ID of the BWP serving as the dormant BWP in the cell), and / or a sixth high-level parameter (e.g., firstWithinActiveTimeBWP-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, e.g., to leave Scell ​​dormancy), and / or a seventh high-level parameter (e.g., dormancyGroupWithinActiveTime-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, including a fifteenth high-level parameter (e.g., DormancyGroupID-r16) for configuring the dormancy group ID. In some embodiments, the terminal device does not need to monitor the PDCCH on the Scell ​​or the dormant BWP, nor does it need to monitor the PDCCH for the 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.

[0076] For each activated SCell (activated SCell) configured with a dormant BWP and / or dormant group ID, the terminal device enters or leaves the dormant BWP of the SCell through BWP switching. For example, for an activated SCell described above, when instructed to enter a dormant BWP (that is, the BWP instructed to be activated is a dormant BWP), the DL BWP configured / provided by dormantBWP-Id is activated; when instructed to leave the dormant BWP (that is, the BWP instructed to be activated is a dormant BWP), the DL BWP configured / provided by firstWithinActiveTimeBWP-Id is activated.

[0077] In some embodiments, the serving cell configuration information of the first cell or one of the eleventh high-level parameters therein may include or not include (presence or absence) a ninth high-level parameter (domancyDCI-1-3) and / or a tenth high-level parameter (domancyDCI-0-3), and the ninth high-level parameter is used to indicate that the first DCI format includes the first information field. The tenth high-level parameter is used to indicate that the second DCI format includes the first information field. For example, if the serving cell configuration information or the eleventh high-level parameter includes the ninth high-level parameter, the first DCI format sent (by the network device) / received (by the terminal device) on the first cell (may) include the first information field. For another example, if at least one of the twelfth high-level parameters in the eleventh high-level parameters includes the ninth high-level parameter, the first DCI format sent / received on the first cell (may) include the first information field. For another example, if one of the twelfth high-level parameters in the eleventh high-level parameters includes the ninth high-level parameter, the first DCI format sent / received on the first cell may include the first information field when scheduling cells in the first cell set corresponding to the twelfth high-level parameter (i.e., the first cell set configured by the first high-level parameter in the twelfth high-level parameter); if one of the twelfth high-level parameters in the eleventh high-level parameters does not include the ninth high-level parameter, the first DCI format sent / received on the first cell may not include the first information field when scheduling cells in the first cell set corresponding to the twelfth high-level parameter. If the serving cell configuration information or the eleventh high-level parameter includes the tenth high-level parameter, the second DCI format sent / received (by the network device) / received (by the terminal device) on the first cell may include the first information field. For another example, if at least one of the twelfth high-level parameters in the eleventh high-level parameters includes the tenth high-level parameter, the second DCI format sent / received on the first cell may include the first information field. For another example, if a twelfth higher-layer parameter in the eleventh higher-layer parameter includes the tenth higher-layer parameter, the second DCI format sent / received on the first cell (may) include the first information field when scheduling cells in the first cell set corresponding to the twelfth higher-layer parameter (i.e., the first cell set configured by the second higher-layer parameter in the twelfth higher-layer parameter); if a twelfth higher-layer parameter in the eleventh higher-layer parameter does not include the tenth higher-layer parameter, the second DCI format sent / received on the first cell does not (may) include the first information field when scheduling cells in the second cell set corresponding to the twelfth higher-layer parameter.In some embodiments, the first information field in the first DCI format and the second DCI format respectively exists only when the DCI format is carried by a Pcell and / or a PScell ​​and / or a SpCell and / or a primary cell and / or a PUCCH Scell ​​and / or a Scell ​​not configured with a dormant BWP and / or a sleep group ID and / or a cell not configured with a dormant BWP and / or a sleep group ID and / or on a PDCCH during a non-continuous reception (DRX) activation time, and / or the terminal device is configured with at least 2 DL BWPs for a Scell.

In other words, the first cell is not a cell not configured / provided with a dormant BWP and / or a dormant group ID, and the ninth higher layer parameter and / or the tenth higher layer parameter may not be present. Otherwise, they may be present, but may be present, if desired.

[0087] Example 5: In the serving cell configuration of a cell where the fifth higher layer parameter and / or the sixth higher layer parameter and / or the seventh higher layer parameter and / or the fifteenth higher layer parameter do not exist / do not include (or in other words, if the fifth higher layer parameter and / or the sixth higher layer parameter and / or the seventh higher layer parameter and / or the fifteenth higher layer parameter do not exist / do not include), the ninth higher layer parameter and / or the tenth higher layer parameter may optionally exist; otherwise, they may not exist.

In other words, for the cell set that is not scheduled by the SpCell / primary cell In the cell set configuration of the cell set that is scheduled by the Scell ​​or the Scell ​​that is not 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 fifteenth high-level parameter, and / or does not include the SpCell / primary cell or the SCell that is not 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 fifteenth high-level parameter, the ninth high-level parameter and / or the tenth high-level parameter does not exist; otherwise, it may optionally exist.

[0094] Example 3: The ninth higher-level parameter and / or the tenth higher-level parameter may optionally exist.

[0095] In some embodiments, when the first cell is a PUCCH cell or an Scell, the serving cell configuration information of the first cell does not include the ninth high-level parameter and / or the tenth high-level parameter, or the ninth high-level parameter and / or the tenth high-level parameter included in the serving cell configuration information of the first cell is ignored by the terminal device. In other words, when the first cell is a PUCCH cell or an Scell, the first DCI format and / or the second DCI format does not include the first information field, the first DCI format and / or the second DCI format does not indicate SCell dormancy, or the first information field cannot be used to indicate SCell dormancy.

[0096] In some embodiments, the ninth higher layer parameter and / or the tenth higher layer parameter is included in the search space information in the serving cell configuration information or in the cross-carrier scheduling configuration information (eg, CrossCarrierSchedulingConfig).

[0097] For the convenience of description, various information fields in the first DCI format and / or the second DCI format are first described below.

[0098] In some embodiments, the first DCI format and / or the second DCI format includes a second information field, includes or excludes the first information field and / or the third information field and / or the fourth information field, and includes or excludes one or more fifth information fields. Specifically, when to include and when not to include will be explained in the embodiments described below.

[0099] In some embodiments, the second information field (Frequency domain resource assignment) is used to indicate frequency domain resource allocation.

[0100] For example, for the first 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 first cell combination or the scheduled 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 scheduled first cell set is indicated by the fourth information field in the first DCI format or configured by the first high-level parameter (when the first DCI format does not include the fourth information field). For example, when the (corresponding) first cell combination list (or the third high-level parameter) is not configured (for the scheduled first cell set), is equal to the number of cells in the scheduled first cell set, when the (corresponding) first cell combination list (or the third higher layer parameter) is configured (for the scheduled first cell set), is equal to the number of cells in the first cell combination to be scheduled, 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 first cell combination or the scheduled first 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.

[0101] 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 second cell combination or the scheduled second cell set. The scheduled second 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 scheduled second cell set is indicated by the fourth information field in the second DCI format or configured by the second high-level parameter (when the first DCI format does not include the fourth information field). For example, when (for the scheduled second cell set) no (corresponding) second cell combination list (or fourth high-level parameter) is configured, is equal to the number of cells in the scheduled second cell set, when a (corresponding) second cell combination list (or fourth higher layer parameter) is configured (for the scheduled second cell set), is equal to the number of cells in the second cell combination to be scheduled, 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.

[0102] 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 one 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) 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),

[0103] 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 fourth higher layer parameter (e.g., ScheduledCellCombo-ListDCI-0-3) or the number of cells configured by the one 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).

[0104] 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).

[0105] For example, the second information field in the first DCI format indicates scheduled cells and / or unscheduled cells from the first scheduled cell set (indicated by the fourth information field or configured by the first higher-layer parameter (when the first DCI format does not include the fourth information field)). Assuming that the first scheduled cell set includes four cells, the second information field includes four information blocks (block number 1, block number 2, block number 3, block number 4), which correspond one to each of the four cells. If all bits in the information block corresponding to a cell are set to the second specific value, the cell is not scheduled; otherwise, the cell is scheduled.

[0106] For another example, the second information field in the first DCI format indicates the scheduled cells and / or unscheduled cells from the scheduled first cell combination (indicated by the third information field or configured by the third high-level parameter (when the first DCI format does not include the third information field)). 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 second specific value, the cell is not scheduled; otherwise, the cell is scheduled. For example, as shown in Table 3 below, only the bits in information block 1 are not set to the second 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.

[0107] Table 3

[0108] 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.

[0109] 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 first cell combination indicated by the third information field.

[0110] In some embodiments, the third information field (Scheduled cells indicator) is used to indicate the scheduled cells (or, to indicate the scheduled first cell combination or the second cell combination). For example, in the first DCI format, the third information field indicates the scheduled cells from the scheduled (first) cell set (by indicating a first cell combination). The scheduled (first) cell set is indicated by the fourth information field in the first DCI format or configured by the first high-level parameter (when the first DCI format does not include the fourth information field). For another example, in the second DCI format, the third information field indicates the scheduled cells from the scheduled (second) cell set (by indicating a second cell combination). The scheduled (second) cell set is indicated by the fourth information field in the second DCI format or configured by the second high-level parameter (when the second DCI format does not include the fourth information field).

[0111] In some embodiments, the first DCI format and / or the second DCI format includes or does not include the third information field.

[0112] For example, for the first DCI format, when the third high-level parameter (eg ScheduledCellCombo-ListDCI-1-3) (for / corresponding to the first scheduled cell set) is not configured (or, when the first scheduled cell set does not include the first 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 first 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.

[0113] For example, for the second DCI format, when the fourth high-level parameter (eg ScheduledCellCombo-ListDCI-0-3) (for / corresponding to the scheduled second cell set) is not configured (or, when the scheduled first cell set does not include the first 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 second 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.

[0114] 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 among multiple (first) cell sets configured (the eleventh higher layer parameter). In a second DCI format, the fourth information field indicates a scheduled (second) cell set from among multiple (second) cell sets configured (the eleventh higher layer parameter).

[0115] 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). 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.

[0116] Table 1

[0117] In some embodiments, the fourth information field in the first DCI format includes bits, where N set1It is the number of the first cell set 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 scheduled (first) cell set is shown in Table 2 below. When the value of the fourth information field is 0 (decimal), the scheduled cell set is the first cell set including the first cell set 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 se2t It is the number of the second cell set 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 Table 2 below. When the value of the fourth information field is 0 (decimal), the scheduled cell set is the first cell set configured by the eleventh higher layer parameter that includes the second cell set, or in other words, the second cell set.

[0118] Table 2

[0119] In some embodiments, the fourth information field indicates the scheduled cell set by indicating or based on the cell set ID (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 corresponding to the first cell set scheduled. When the value of the fourth information field is 0 (decimal), the first cell set scheduled is the first cell set corresponding to the 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 second cell set scheduled. When the value of the fourth information field is 0 (decimal), the second cell set scheduled is the second cell set corresponding to the cell set ID = 0. The cell set ID corresponding to a first cell set or a second cell set is the cell set ID configured by the thirteenth high-level parameter in the twelfth configuration information including the first high-level parameter for configuring the first cell set or the second high-level parameter for configuring the second cell set.

[0120] In some embodiments, for the first DCI format, the terminal device does not expect the fourth information field to indicate a cell set that does not include the first cell set, and / or does not expect the value of the fourth information field to be equal to the value of the cell set ID configured by the thirteenth high-level parameter in the twelfth high-level parameter (egMC-DCI-SetofCells) in an entry that does not include the first high-level parameter (in the eleventh high-level parameter). For the first DCI format, the terminal device does not expect the fourth information field to indicate a cell set that does not include the second cell set, and / or does not expect the value of the fourth information field to be equal to the value of the cell set ID configured by the thirteenth high-level parameter in the twelfth high-level parameter (in the eleventh high-level parameter) in an entry that does not include the second high-level parameter (egMC-DCI-SetofCells).

[0121] In some embodiments, the first DCI format and / or the second DCI format does not include the fourth information field.

[0122] 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 a transmitted / received first DCI format, the corresponding scheduled cell set is the first 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 a transmitted / received second DCI format, the corresponding scheduled cell set is the second cell set configured by the twelfth higher-layer parameter or the second higher-layer parameter.

[0123] For example, when the eleventh higher-layer parameter includes only a twelfth higher-layer parameter including the first higher-layer parameter, the first DCI format does not include the fourth information field. For a sent / received first DCI format, its corresponding scheduled cell set is the first cell set configured by the twelfth higher-layer parameter or the first higher-layer parameter.

[0124] For example, when the eleventh higher-layer parameter includes only one twelfth higher-layer parameter including the second higher-layer parameter, the second DCI format does not include the fourth information field.

[0128] In some embodiments, a first information field (Scell ​​dormancy indication) is used to indicate Scell ​​dormancy. The first information field includes a first bitmap. How the first information field indicates Scell ​​dormancy will be described later. When the ninth higher-layer parameter and / or the tenth higher-layer parameter are not enabled, for example, when the ninth higher-layer parameter and / or the tenth higher-layer parameter are not included or present in the serving cell configuration information, the first information field does not exist, or the number of bits in the first information field is 0. When the ninth higher-layer parameter and / or the tenth higher-layer parameter are included or present in the serving cell configuration information, the number of bits in the first information field is determined by the number of Scell ​​groups and / or the number of dormancy group IDs (the seventh higher-layer parameter (DormancyGroupID-r16)).

[0129] In some embodiments, when the value of a bit of the first bitmap is 0, for each UE of an activated SCell in the configured corresponding SCell group, the activated DL BWP (provided by the fifth higher-level parameter) is indicated; when the value of a bit of the first bitmap is 1, when the currently activated DL BWP is a dormant DL BWP, for each UE of an activated SCell in the configured corresponding SCell group, the activated DL BWP (provided by the sixth higher-level parameter) is indicated; when the currently activated DL BWP is not a dormant DL BWP, for each UE of an activated SCell in the configured corresponding SCell group, the currently activated DL BWP is indicated. The terminal device sets the activated DL BWP to the indicated activated DL BWP.

[0130] In some embodiments, the ninth higher-level parameter and / or the tenth higher-level parameter are further restricted by the fifth higher-level parameter and / or the sixth higher-level parameter and / or the seventh higher-level parameter and / or the fifteenth higher-level parameter. For example, only when the seventh higher-level parameter and / or the fifteenth higher-level parameter DormancyGroupID-r16 are configured / provided, is the presence of the first information field of the first DCI format and / or the second DCI format configured using the ninth higher-level parameter and / or the tenth higher-level parameter, respectively?

[0131] For example, for the second DCI format, when the tenth high-level parameter is not enabled, the number of bits in the first information field is 0. Otherwise, it can be X (for example, 1, 2, 3, 4, 5) bits. The number of bits or the bitmap is determined according to the number of different DormancyGroupID(s) configured by the seventh high-level parameter dormancyGroupWithinActiveTime. The first information field includes a first bitmap, and each bit in the first bitmap corresponds to a Scell ​​group and / or a sleep group ID (configured by the seventh high-level parameter dormancyGroupWithinActiveTime). The MSB to LSB of the first information field or the first bitmap correspond to the first to the last Scell ​​group in ascending order of the sleep group ID. The above-mentioned Scell ​​group is identified by a sleep group ID. For example:

[0132] For example, for the first DCI format, when the ninth high-level parameter is not enabled, the number of bits in the first information field is 0. Otherwise, it can be X (for example, 1, 2, 3, 4, 5) bits. The number of bits or the bitmap is determined according to the number of different DormancyGroupID(s) configured by the seventh high-level parameter dormancyGroupWithinActiveTime. The first information field includes a first bitmap, and each bit in the first bitmap corresponds to a Scell ​​group and / or a sleep group ID (configured by the seventh high-level parameter dormancyGroupWithinActiveTime). The MSB to LSB of the first information field or the first bitmap correspond to the first to the last Scell ​​group in ascending order of the sleep group ID. The above-mentioned Scell ​​group is identified by a sleep group ID. For example:

[0133] In some embodiments, the ninth and / or tenth higher-level parameters are not limited by the fifth and / or sixth and / or seventh higher-level parameters. For example, even if the seventh and / or fifteenth higher-level parameters DormancyGroupID-r16 are not configured or provided, the first information field of the first DCI format and / or the second DCI format may be configured using the ninth and / or tenth higher-level parameters, respectively. For example:

[0134] For example, for the second DCI format, when the tenth high-level parameter is not enabled, the number of bits in the first information field is 0. Otherwise, when the seventh high-level parameter and / or the fifteenth high-level parameter are not configured / provided, the number of bits in the first information field is 0. When the seventh high-level parameter and / or the fifteenth high-level parameter are configured / provided, it can be X (for example, 1, 2, 3, 4, 5) bits. The number of bits or the bitmap is determined according to the number of different DormancyGroupID(s) configured by the seventh high-level parameter dormancyGroupWithinActiveTime. The first information field includes a first bitmap, and each bit in the first bitmap corresponds to a Scell ​​group and / or a sleep group ID (configured by the seventh high-level parameter dormancyGroupWithinActiveTime). The MSB to LSB of the first 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. For example:

[0135] For example, for the first DCI format, when the ninth higher layer parameter is not enabled, the number of bits in the first information field is 0. Otherwise, when the seventh higher layer parameter and / or the fifteenth higher layer parameter are not configured / provided, the number of bits in the first information field is 0. When the seventh higher layer parameter and / or the fifteenth higher layer parameter are configured / provided, the number of bits in the first information field may be X (e.g., 1, 2, 3, 4, or 5) bits. The number of bits or the bitmap is determined according to the number of different DormancyGroupID(s) configured by the seventh higher layer parameter dormancyGroupWithinActiveTime. The first information field includes a first bitmap, each bit in the first bitmap corresponds to a Scell ​​group and / or a sleep group ID (configured by the seventh higher layer parameter dormancyGroupWithinActiveTime). The MSB to LSB of the first 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.

[0137] In this embodiment, the first DCI format and / or the second DCI format uses only the first information field to indicate Scell ​​dormancy, where using only the first information field means, for example, that bits in other information fields in the DCI format do not correspond to Scells or Scell ​​groups.

[0138] In this embodiment, the first DCI format and / or the second DCI format includes the first information field, and one bit of the first information field corresponds to a Scell ​​group and / or a dormancy group ID (DormancyGroupID).

[0139] In this embodiment, the first information field includes a first bitmap, and each bit in the first bitmap corresponds to a Scell ​​group and / or a sleep group ID. The MSB to LSB of the first information field or the first bitmap correspond to the first to the last Scell ​​groups in ascending order of the sleep group ID. The number of bits included in the first information field or the first bitmap is determined by the number of Scell ​​groups and / or the number of sleep group ID(s). The cell used to send the DCI format (i.e., the first cell) and the Scell(s) in the Scell ​​group belong to the same or different cell groups and / or the same or different PUCCH groups. The cell group includes MCG and / or SCG, that is, it is assumed that they belong to the same cell group, i.e., both belong to MCG, or both belong to SCG.

[0140] In some embodiments, the first DCI format and / or the second DCI format can be scheduled while indicating dormancy. The first DCI format and / or the second DCI format schedules only the first cell (the cell used to send the DCI format) and / or the second cell, where the second cell includes a Pcell and / or a PScell ​​and / or an SpCell and / or a primary cell and / or a PUCCH Scell ​​and / or an Scell ​​not configured with a dormant BWP and / or a dormancy group ID and / or a cell not configured with a dormant BWP and / or a dormancy group ID and / or a cell not indicated as dormant by the first information field in the first DCI format and / or the second DCI format. The first cell and the second cell may or may not be the same cell, or the second cell may or may not include the first cell.

[0143] In this embodiment, the first DCI format may further include a third information field for indicating scheduled cells, where the cells indicated by the third information field include only the first cell and / or the second cell. The third information field indicates the scheduled cells from the scheduled first cell set.

[0144] In this embodiment, the second DCI format may further include a third information field for indicating scheduled cells, where the cells indicated by the third information field include only the first cell and / or the second cell. The third information field indicates the scheduled cells from the scheduled second cell set.

[0146] In this embodiment, the first DCI format may further include a fourth information field for indicating a first scheduled cell set (scheduled cell set), where the first cell set indicated by the fourth information field includes the first cell and / or the second cell. The second DCI format may further include a fourth information field for indicating a second scheduled cell set (scheduled cell set), where the second cell set indicated by the fourth information field includes the first cell and / or the second cell.

[0147] Example 1: When only the first information field is used to indicate that an Scell ​​is dormant, the cell is scheduled, but the Scell ​​that may be instructed to be dormant (the Scell ​​configured with a dormant BWP and / or dormant group ID) is not scheduled.

[0151] Case 2: The third higher-layer parameter for the scheduled cell set is not configured, and the (scheduled) cells indicated by the second information field only include SpCell / primary cell (that is, the second information field only indicates SpCell / primary cell). The second information field only schedules cells belonging to the first cell and / or the second cell, and does not schedule cells other than the first cell and / or the second cell; The fourth higher-layer parameter for the scheduled cell set is not configured, and the (scheduled) cells indicated by the second information field only include SpCell / primary cell (that is, the second information field only indicates SpCell / primary cell).

For example, only cells that are not indicated as dormant by the first information field are scheduled (or, only cells that do not belong to a cell group indicated as dormant by the first information field are scheduled.

[0156] In some embodiments, the first DCI format and / or the second DCI format can schedule a third cell while indicating that the Scell ​​is dormant, and the third cell includes a cell indicated as dormant by the first information field and / or a cell configured with a dormant BWP and / or a dormant group ID. The cell scheduled by the first DCI format and / or the second DCI format is configured by a first high-level parameter and / or a second high-level parameter and / or is indicated by the second information field and / or the third information field in the first DCI format and / or the second DCI format. For the information field including one or more information blocks in the first DCI format and / or the second DCI format (the information field including the information block is as described above and will not be repeated here), the information block corresponding to the third cell is set to an invalid value or a default value and / or is reserved and / or ignored by the terminal device.

[0157] Example 3: When only the first information field is used to indicate that the Scell ​​is dormant, the Scell ​​indicated by the field as dormant (or entering dormancy, or entering / activating / switching to dormant BWP) (or the Scell ​​belonging to the Scell ​​group indicated by the field as dormant (or entering dormancy, or entering / activating / switching to dormant BWP)) can be scheduled. For example, when the scheduled cells include a cell indicated by the first information field as dormant, for the information field of Type2 (including one or more information blocks), the information block corresponding to the cell indicated as dormant is set to an invalid value and / or reserved and / or the terminal device ignores the information block corresponding to the cell, and for the information field of Type1B (based on a configuration indication including one or more lists, wherein one list includes configuration indexes corresponding to multiple cells respectively), the index corresponding to the cell is set to an invalid value and / or reserved and / or the terminal device ignores the index corresponding to the cell. In other words, when the scheduled cells include cells belonging to a Scell ​​group indicated as dormant by the first information field, for the Type 2 information field, the information block corresponding to the cell belonging to the Scell ​​group is set to an invalid value and / or reserved and / or the UE ignores the information block corresponding to the cell, and for the Type 1B information field, the index corresponding to the cell is set to an invalid value and / or reserved and / or the terminal device ignores the index corresponding to the cell.

[0158] In some embodiments, the first DCI format and / or the second DCI format do not schedule cells. That is, the first DCI format and / or the second DCI format supports scheduling of one or more cells, but no cells are actually scheduled. In other words, while indicating dormancy, no scheduling is performed. For example, the bit in the second information field is set to a second specific value. Therefore, scheduling does not occur to a Scell ​​that may be indicated as dormant.

[0159] In some embodiments, the terminal device determines, based on the second information field and / or the third information field, that the first information field in the DCI format indicates Scell ​​dormancy in the manner described above. For example, when the scheduled cells indicated by the second information field and / or the third information field only include the first cell and / or the second cell, or when the second information field and / or the third information field do not indicate a scheduled cell or indicate no scheduled cell or an unscheduled cell, the first information field in the DCI format indicates Scell ​​dormancy in the manner described above. When the scheduled cells indicated by the second information field and / or the third information field include cells other than the first cell and / or the second cell, or when the second information field and / or the third information field indicate a scheduled cell, the first information field in the DCI format is invalid and / or is reserved and / or does not indicate Scell ​​dormancy.

[0160] (II) The following describes how the first DCI format and / or the second DCI format supports a cell dormancy indication for a (per) secondary cell, including whether simultaneous scheduling of cells (PDSCH and / or PUSCH of the cell) is supported.

[0161] In this embodiment, the first DCI format and / or the second DCI format may include the first information field, and one bit of the first information field and / or one or more fifth information fields in the first DCI format corresponds to one Scell. That is, rather than using only the first information field to indicate Scell ​​dormancy, the first information field and one or more fifth information fields may be used in combination to indicate Scell ​​dormancy, or the first information field may be retained while one or more fifth information fields are used in combination to indicate Scell ​​dormancy. In other words, in addition to their own indication function as described above, the one or more fifth information fields may also be used to indicate Scell ​​dormancy.

[0162] In some embodiments, the first information field and / or the one or more fifth information fields include / provide a second bitmap, wherein each bit in the second bitmap corresponds to a Scell. The MSB to LSB of the first information field and / or one or more other 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 (regardless of whether a Scell ​​is configured with a dormancy BWP and / or a sleep group ID). The cell used to transmit the DCI format (the first cell) and the Scell ​​belong to the same or different cell groups and / or the same or different PUCCH groups. The cell group includes MCG and / or SCG, that is, it is assumed that they belong to the same cell group, that is, they all belong to MCG, or they all belong to SCG.

[0163] In some embodiments, the second bitmap is composed of / provided by part or all of the bits of each of the first information field and / or the one or more fifth information fields. For example, the part or all of the bits of each information field are used as the bits from the MSB to the LSB in the second bitmap in descending order of the position (or the order in which they are listed) of the part or all of the bits of each information field in each information field and / or the position (or the order in which they are listed) of these information fields in the corresponding DCI format. For example, the bits of the second bitmap from MSB to LSB sequentially include {MSB to LSB in the MCS domain for TB1, MSB to LSB in the NDI domain for TB1, MSB to LSB in the RV for TB1, MSB to LSB in the HARQ process number domain, MSB to LSB in the Antenna ports domain, DMRS sequence initialization MSB to LSB}, and for another example, sequentially include {MSB to LSB in the MCS domain for TB1, MSB to LSB in the NDI domain for TB1, MSB to LSB in the RV for TB1, MSB to LSB in the HARQ process number domain, MSB to LSB in the first information domain}, and for another example, sequentially include {MSB to LSB of information block 1 in the MCS domain for TB1, MSB to LSB of information block 1 in the NDI domain for TB1, MSB to LSB of information block 1 in the RV domain for TB1, MSB to LSB in the HARQ process number domain, MSB to LSB in the first information domain}

[0164] In some embodiments, when the value of one bit of the second bitmap is 0, for the UE corresponding to the activated SCell, an activation DL BWP (provided by the fifth higher-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, an activation DL BWP (provided by the sixth higher-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.

[0165] In this embodiment, the first DCI format and / or the second DCI format does not include the sixth information field (one-shot HARQ-ACK request), or the bits in the sixth information field included in the first DCI format and / or the second DCI format are set to a first specific value, which may include 0. That is, in this embodiment, all bits in the sixth information field are set to 0.

[0166] In this embodiment, the embodiment of the second information field is described as follows. The bits in the second information field in the first DCI format and / or the second DCI format are set to a second specific value. This includes: all bits of one or more first information blocks in the second information field are set to 0 or 1 respectively. All bits of a first information block corresponding to a cell configured with the first resource allocation type (resource allocation type 0) are set to a second specific value, which is 0; all bits of a first information block corresponding to a cell configured with the second resource allocation type (resource allocation type 1) are set to a second specific value, which is 1; all bits of a first information block corresponding to a cell configured with a dynamic switching resource allocation type (i.e., a DCI indicates whether resource allocation type 0 or 1 is used) are set to a second specific value, which is 0 or 1. The one or more first information blocks in the second information field include all or part of the information blocks in the second information field. Or the one or more first information blocks include at least one information block, or at least two information blocks in the second information field.

[0167] For example, when the one or more first information blocks are all (each) information blocks in the second information field, the first DCI format and / or the second DCI format do not support simultaneous scheduling of cells. When the one or more first information blocks are part of the information blocks in the second information field (at least one information block or at least two information blocks, for example, including the first information block), simultaneous scheduling of cells can be supported (scheduling using the remaining second information blocks). That is, the second information field also includes a second information block, and bits in one or more second information blocks in the second information field are not set to the second specific value, and / or the second information block in the second information field is used to provide information for scheduling PDSCH. The one or more second information blocks in the second information field include information blocks in the second information field other than the one or more first information blocks.

[0168] The following describes how to use the first information field and / or one or more fifth information fields to indicate SCell sleep using the second bitmap.

[0169] In some embodiments, the specific composition of the first information field and the fifth information field is as described above and will not be repeated here. The modulation and coding mode and / or new data indication and / or redundancy version are for the first transport block (TB1) and / or the second transport block (TB2). Specifically, for the fifth information field including one or more information blocks (e.g., the modulation and coding mode and / or new data indication and / or redundancy version and / or number of HARQ processes, whether an antenna port includes an information block depends on the configuration, and other fifth information fields include information blocks by default), one bit in one or more third information blocks in the fifth information field corresponds to one Scell. Specifically, the one or more third information blocks include all or part of the information blocks in the fifth information field. Specifically, the one or more third information blocks include the first N2 information blocks in the fifth information field and / or the last N3 information blocks in the fifth information field, or include the N4th information block in the fifth information field, or include an information block in the fifth information field that corresponds to the first information block in the second information field.

[0170] In this embodiment, the corresponding information block means: a third information block corresponds to a first information block in the second information field, and / or corresponds to the same cell as a first information block in the second information field, and / or has the same sequence number as a first information block in the second information field.

[0171] In some embodiments, the fifth information field further includes a fourth information block, wherein one or more fourth information blocks are not used to indicate Scell ​​dormancy, and / or all (any) bits in the fourth information block in the fifth information field do not correspond to an Scell, and / or the fourth information block in the fifth information field is used to provide information for scheduling a PDSCH. The one or more fourth information blocks include information blocks in the fifth information field other than the one or more third information blocks.

[0172] In some embodiments, the number of third information blocks in the fifth information field is the same as or different from the number of first information blocks in the second information field. The number of information blocks in the fifth information field is the same as or different from the number of information blocks in the second information field.

[0173] The following examples illustrate the implementation of each information field of per SCell indicating SCell sleep:

[0174] In some embodiments, for the second DCI format, the first transport block and / or the second transport block are involved or not involved.

[0175] Example 1: The first DCI format does not include the sixth information field (one-shot HARQ-ACK request), or the bits in the sixth information field included in the first DCI format are set to 0. All bits of each information block of the second information field (all first information blocks, excluding the second information block): all bits of the first information block corresponding to the cell configured with resource allocation type 0 are set to 0, all bits of the first information block corresponding to the cell configured with the second resource allocation type (resource allocation type 1) are set to 1, and all bits of the first information block corresponding to the cell configured with dynamic resource allocation switching are set to a second specific value of 0 or 1. In this case, the first information field exists (reserved, but not used to indicate SCell dormancy). The fifth information field (modulation and coding mode and / or new data indication and / or redundancy version) corresponding to the first transport block and the antenna port and DMRS sequence initialization are used to indicate SCell dormancy, forming a second bitmap, in which one bit in the second bitmap corresponds to one Scell. The MSB to LSB of the second bitmap correspond to the Scells with the lowest to highest Scell ​​index in ascending order of Scell ​​index.

[0176] Example 2: The first DCI format does not include the sixth information field (one-shot HARQ-ACK request), or the bits in the sixth information field included in the first DCI format are set to 0. All bits of each information block in the second information field (all first information blocks, excluding the second information block): all bits of the first information block corresponding to the cell configured with resource allocation type 0 are set to 0, all bits of the first information block corresponding to the cell configured with the second resource allocation type (resource allocation type 1) are set to 1, and all bits of the first information block corresponding to the cell configured with the dynamic switching resource allocation type are set to a second specific value of 0 or 1. In this case, the first information field exists (reserved, but not used to indicate SCell dormancy). The first information block (third information block N2=1, N4=1) of the fifth information field having multiple information blocks (e.g., the modulation and coding mode and / or new data indication and / or redundancy version) is used to indicate SCell dormancy. The cascaded information forms a second bitmap, in which one bit in the second bitmap corresponds to one Scell. The MSB to LSB of the second bitmap correspond to Scells with the lowest to highest Scell ​​index in ascending order of Scell ​​index.

[0177] In the above-mentioned Example 1 and Example 2, simultaneous scheduling of cells is not supported, that is, the first DCI format and / or the second DCI format does not support scheduling of one or more cells.

[0178] Example 3: The first DCI format and / or the second DCI format includes a third information field, which indicates at least two scheduled cells, and all bits in at least one information block (e.g., including the first, but not limited to, first information block) in the second information field: all bits of the first information block corresponding to the cell configured with resource allocation type 0 are set to 0, all bits of the first information block corresponding to the cell configured with the second resource allocation type (resource allocation type 1) are set to 1, and all bits of the first information block corresponding to the cell configured with the dynamic switching resource allocation type are set to a second specific value of 0 or 1. At this time, the first information field exists (reserved, but not used to indicate SCell dormancy). At least one of the following first information fields and / or fifth information fields is used to indicate SCell dormancy: (the third information block is cascaded to form the second bitmap)

[0179] Modulation and coding mode of the first transport block (1)

[0180] New data indication for the first transport block (2)

[0181] Redundancy version (3) of the first transport block (if any)

[0182] Number of HARQ processes (4)

[0183] Antenna ports (5)

[0184] DMRS sequence initialization (6)

[0185] First information block (7)

[0186] Wherein, for (1)-(4), the information block (third information block) corresponding to at least one information block (first information block) in the second information field is used for SCell sleep indication. For example, the other information blocks (if any, the fourth information block) are respectively used to provide information for scheduling the PDSCH in the cell corresponding to the other information blocks (second information blocks) in the second information field. Wherein, for (3), the one or more information blocks corresponding to at least one information block in the second information field may respectively include 0 bits (whether each information block in the information field includes only 0 bits depends on the configuration). In this case, it can also be said that the fifth information field or the one or more information blocks (fourth information blocks) are not used for SCell sleep indication.

[0187] For (5), when it is configured as Type 2, the implementation is the same as (1)-(4) above. When it is configured as Type-1a, this field is used for SCell sleep indication, and for the PDSCH scheduled in the cell corresponding to the other information blocks (second information blocks) in the second information field, a predefined antenna port is used (for example, assuming a default value, but not limited thereto).

[0188] For (6), this information field is used for SCell sleep indication. For the PDSCH scheduled in the cell corresponding to the other information blocks (second information blocks) in the above-mentioned second information field, it is assumed that the DMRS sequence is initialized to 0 or 1.

[0189] For (7), all or part of the bits in the information field are used for SCell sleep indication.

[0190] Example 4: The first DCI format and / or the second DCI format includes a third information field, which indicates at least three scheduled cells. When all bits of at least two (this is to ensure that the following information fields also have at least two information blocks for indicating Scell ​​dormancy, and the number of bits is sufficient) information blocks in the second information field (e.g., the first information block includes the first two information blocks, but is not limited to this): all bits of the first information block corresponding to the cell configured with resource allocation type 0 are set to 0, all bits of the first information block corresponding to the cell configured with the second resource allocation type (resource allocation type 1) are set to 1, and all bits of the first information block corresponding to the cell configured with the dynamic switching resource allocation type are set to a second specific value of 0 or 1, then the first information field exists (reserved, but not used to indicate SCell dormancy). At least one of the following first information fields and / or fifth information fields is used to indicate SCell dormancy: (the third information blocks are cascaded to form the second bitmap)

[0191] Modulation and coding mode of the first transport block (1)

[0192] New data indication for the first transport block (2)

[0193] Redundancy version (3) of the first transport block (if any)

[0194] Number of HARQ processes (4)

[0195] First information block (7)

[0196] For (1)-(4), the information block (third information block) corresponding to at least two information blocks (first information blocks) in the second information field is used for SCell sleep indication. For example, the other information blocks (if any, the fourth information block) are used to provide information for scheduling the PDSCH in the cell corresponding to the other information blocks (second information blocks) in the second information field.

[0197] For (7), all or part of the bits in the information field are used for SCell sleep indication.

[0198] Example 5: The first DCI format and / or the second DCI format does not include the third information field, and the third higher layer parameter and / or the fourth higher layer parameter for the scheduled cell set includes only one entry. The implementation of Example 3 or 4 may be adopted.

[0199] Example 6: The third higher layer parameter and / or the fourth higher layer parameter for the scheduled cell set is not configured. The method in Example 1 or 2 can be used (PDSCH cannot be scheduled simultaneously).

[0200] Currently, since more than 10 Scells (e.g., 15) may be configured in an MCG or SCG, per-Scell ​​indication may require the same number of information bits. Regarding the existing DCI format 1_1, since the original purpose of introducing this DCI format was to schedule a single cell, the information fields or information bits included in this DCI format were also designed with this goal in mind. When using this DCI format for per-Scell ​​Scell ​​sleep indication, information bits originally related to scheduling PDSCHs must be used, and these information bits cannot be used for indications related to scheduling PDSCHs. This results in the fact that if a DCI format 1_1 is used for per-Scell ​​Scell ​​sleep indication, this DCI format 1_1 cannot simultaneously schedule PDSCHs.

[0201] In the embodiment of the present application, the first DCI format and the second DCI format are introduced to support scheduling of multiple (two or more) cells. The information fields or information bits included in the first DCI format and the second DCI format are also designed for this purpose (for example, some information fields include multiple information blocks, each providing information related to a PDSCH scheduled for different cells). When the first DCI format and the second DCI format are used for per-Scell ​​Scell ​​sleep indication, through the above-mentioned examples 3, 4, or 5, i.e., one first DCI format and one second DCI format can simultaneously perform per-Scell ​​Scell ​​sleep and PDSCH scheduling, which can improve resource efficiency.

[0202] In some embodiments, when a first DCI format and a second DCI format can simultaneously perform per-Scell ​​Scell ​​dormancy and PDSCH / PUSCH scheduling, for example, in the above-mentioned example 3, 4, or 5, the scheduled PDSCH / PUSCH is also limited. For details, please refer to the implementation method in (1), for example, the first DCI format and / or the second DCI format only schedules the PDSCH and / or PUSCH of the first cell and / or the second cell, and the second cell includes the Pcell and / or PScell ​​and / or SpCell and / or primary cell and / or PUCCH Scell ​​and / or Scell ​​not configured with dormant BWP and / or dormant group ID and / or cell not configured with dormant BWP and / or dormant group ID and / or cell not indicated as dormant by the second bitmap in the first DCI format and / or the second DCI format. Or the first DCI format and / or the second DCI format schedules the PDSCH and / or PUSCH of a third cell, where the third cell includes a cell indicated as dormant by the second bitmap and / or a cell configured with a dormant BWP and / or a dormant group ID.

[0203] The above types of fifth information fields are merely examples, and the embodiments of the present application are not limited thereto. For example, other types of fifth information fields in the above examples may also be included.

[0204] The above only describes the steps or processes related to the present application, but the present application is not limited thereto. The method of the embodiment of the present application may also include other steps or processes. For the specific content of these steps or processes, reference may be made to the relevant art.

[0205] 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.

[0206] One of the beneficial effects of the embodiments of the present application is that the DCI format that supports scheduling multiple cells through a single DCI can (support) indicate secondary cell dormancy (Scell ​​dormancy), and supports scheduling cells or scheduling cells at different times, which can save terminal device power consumption and improve resource efficiency while achieving multi-carrier enhancement.
