For cell-level scheduling, the Cyclic Redundancy Check (CRC) of the DCI can be scrambled using a Radio Network Temporary Identity (RNTI), and different RNTIs are used to distinguish the types of scheduling content of the scrambled DCI. For example, the SI-RNTI (System Information RNTI) corresponding to system information, the P-RNTI (Paging RNTI) corresponding to paging, etc.

[0088] To better understand the technical solutions provided by the embodiments of the present application, the technical terms involved in the embodiments of the present application are first introduced.
[0089] 1. Cell
[0090] A cell is described by a higher layer (such as protocol layers above the physical layer, such as the radio resource control layer and the media access control layer) from the perspective of resource management or mobility management. The coverage area of each network-side device can be divided into one or more cells. In the case of dual connectivity (DC), a terminal device can establish links with multiple cells, which are divided into two groups: the master cell group (MCG) and the secondary cell group (SCG). If dual connectivity is not performed, the terminal device establishes a link with the cell group of carrier aggregation under a single base station.
[0091] Among them, the primary cell in the MCG is the primary cell (PCell), the primary cell in the SCG is the primary secondary cell (PSCell), and the other cells in the MCG and SCG are secondary cells (SCell). The PCell under the MCG and the SCell under the MCG can be combined together through the single base station carrier aggregation (CA) technology. The PSCell under the SCG and the SCell under the SCG can also be combined together through the single base station carrier aggregation technology.
[0092] A bandwidth part (BWP) is a part of the bandwidth on a certain carrier of a cell. A cell is a general term. For a terminal device, the cell that provides services to it is called the serving cell. The cell involved in the embodiments of the present application may also be the serving cell.
[0093] In NR, a cell may be configured with a downlink carrier, and optionally, at least one uplink carrier. Among them, there are 5 subcarrier spacings (SCS) in NR, and their serial numbers are 0 to 4, corresponding to 15KHz, 30KHz, 60KHz, 120KHz, and 240KHz respectively.
[0094] In NR, a cell may have multiple transmission / reception points (TRP), called multi-TRP. The geographical locations of different TRPs are different and they are not co-located. From the perspective of the terminal device, the statistical characteristics of the channels of these multiple TRPs are different.
[0095] 2. Physical Downlink Control Channel PDCCH and Search Space Set
[0096] A PDCCH in NR may contain L = {1, 2, 4, 8, 16} control channel elements (CCE). Among them, L is called the aggregation level (AL) of the PDCCH. A CCE contains 6 resource element groups (REG), and each REG corresponds to a resource block (RB) on one orthogonal frequency division multiplexing (OFDM) symbol.
[0097] A PDCCH candidate may contain L = {1, 2, 4, 8, 16} CCE. This CCE may send the PDCCH of a terminal device or may not send it. The terminal device can monitor the PDCCH candidate to determine whether there is a PDCCH related to itself.
[0098] A search space with aggregation level L is defined as a set containing several PDCCH candidates each with a size of L control channel units. A search space set is a set containing search spaces with different aggregation levels. A search space set is associated with a control resource set (CORESET). Among them, a CORESET is defined on a cell, contains a set of consecutive or non-consecutive RBs in the frequency domain, and contains 1 / 2 / 3 consecutive OFDM symbols in the time domain. Among them, a search space set can be associated with and only with one CORESET, and a CORESET can be associated with multiple search space sets.
[0099] Please refer to FIG. 1(a). FIG. 1(a) is a schematic diagram of the time-frequency resource size and position corresponding to a possible search space set provided by an embodiment of the present application. As shown in FIG. 1(a), if a certain CORESET is associated with two search space sets, then according to the time-frequency resource parameters of this CORESET and the time domain parameters of the two search space sets associated with it, the time-frequency resource size and position corresponding to each of the two search space sets can be determined. Among them, search space set 1 corresponds to a set of resources, and search space set 2 corresponds to a set of resources.
[0100] A search space set is configured with time domain parameters such as a period and an offset. According to the time domain parameters of the search space set and the time-frequency resource parameters of the CORESET associated with it, a set of time-frequency resource size and position corresponding to this search space set can be determined. The search space configuration includes an aggregation level and the number of PDCCH candidates corresponding to each aggregation level. According to these configuration parameters and the time-frequency resource size and position corresponding to the search space set, through the rules specified by the protocol, the time-frequency resource position of the PDCCH candidates corresponding to this search space set can be determined.
[0101] 3. Types of search space sets and formats of corresponding downlink control information (DCI format)
[0102] There are two types of search space sets: common search space (CSS) and user equipment (UE)-specific search space (USS).
[0103] Downlink control information (DCI) is carried on the PDCCH. There are different formats of DCI, and different DCI formats have different functions and carry different contents. For example, DCI format 0_0 and DCI format 0_1 carry uplink scheduling, and DCI format 1_0, DCI format 1_1, and DCI format 1_2 carry downlink scheduling.
[0104] The DCI formats transmitted in the search space set of the CSS type include DCI format 2_0, DCI format 2_1, DCI format 2_2, DCI format 2_3, DCI format 2_4, DCI format 2_5, DCI format 2_6, DCI format 0_0, and DCI format 1_0.
[0105] The DCI formats that can be transmitted in the search space of the USS type include DCI format 0_0, DCI format 0_1, DCI format 1_0, DCI format 1_1, and DCI format 1_2.
[0106] The DCI and its cyclic redundancy check (CRC) are carried on the PDCCH, and the CRC can be masked with different RNTIs. A DCI format can be masked with different radio network temporary identifiers (RNTIs), and different DCI formats can also be masked with the same RNTI. RNTIs can be used to distinguish content types. For example, the RA-RNTI (Random Access RNTI) for the response of the physical random access channel (PRACH), the T-CRNTI (Temporary C-RNTI) indicating temporary, the TPC-PUCCH-RNTI (Transmit Power Control-Physical Uplink Control Channel-RNTI) for parsing the uplink power control information of the physical uplink control channel (PUCCH), and the TPC-PUSCH-RNTI (Transmit Power Control-Physical Uplink Shared Channel-RNTI) for parsing the uplink power control information of the physical uplink shared channel (PUSCH). RNTIs can also be used to distinguish terminal devices. For example, each terminal device has a C-RNTI (cell RNTI) with the characteristics of the terminal device.
[0107] If the types of search space sets are different, the corresponding DCI formats are different, and the CRCs of the DCIs with different DCI formats are scrambled with different RNTIs. Therefore, a terminal device can monitor PDCCH candidates in one or more of the following search space sets.
[0108] Type0-PDCCH CSS set: Configured on the PCell of the MCG, configured by pdcch-ConfigSIB1 in the master information block (MIB), or configured by pdcch-ConfigSIB1 in PDCCH-ConfigCommon, or configured by searchSpaceZero in PDCCH-Config Common. The CRC of its DCI format is scrambled with SI-RNTI.
[0109] Type0A-PDCCH CSS set: It is configured on the PCell of MCG and configured by pdcch-searchSpaceOtherSystemInformation in PDCCH-ConfigCommon. The CRC of its DCI format is scrambled with SI-RNTI.
[0110] Type1-PDCCH CSS set: It is configured on the PCell and configured by ra-SearchSpace in PDCCH-ConfigCommon. The CRC of its DCI format is scrambled with RA-RNTI or TC-RNTI.
[0111] Type2-PDCCH CSS set: It is configured on the PCell of MCG and configured by the paging search space (paging Search Space) in PDCCH-ConfigCommon. The CRC of its DCI format is scrambled with P-RNTI.
[0112] Type3-PDCCH CSS set: It is configured by the search space with searchSpaceType = common, which is a common search space in PDCCH-Config. The CRC of its DCI format is scrambled with INT-RNTI (interruptedtransmissionindication RNTI), SFI-RNTI (slot format indication RNTI), TPC-PUSCH-RNTI, TPC-PUCCH-RNTI or TPC-SRS-RNTI (transmit power control-sounding referencesymbolsRNTI). It is only on the PCell, and the CRC of one or more of its DCI formats can be scrambled with C-RNTI, subcarrier spacing or CS-RNTI(s).
[0113] Among them, Type0-PDCCH CSS set, Type0A-PDCCH CSS set, Type1-PDCCH CSS set, Type2-PDCCH CSS set and Type3-PDCCH CSS set represent 5 types of common search space sets (CSS set).
[0114] Specific Search Space Set (USS set): Configured by the search space type in PDCCH-Config being UE-specific search space with searchSpaceType = ue-Specific. The CRCs of one or more DCI formats are scrambled with C-RNTI, MCS-C-RNTI (modulation and coding scheme-cell-RNTI) used to indicate the modulation and coding scheme (MCS) table for PUSCH / PDSCH, SP-CSI-RNTI (semi-persistent-channel state information-RNTI) used to indicate the reporting of semi-persistent Channel State Information (CSI) on PUSCH, and CS-RNTI(s) (configured scheduling RNTI) for semi-persistent scheduling (SPS).
[0115] Table 1 shows the association relationships between some possible DCI formats and RNTIs. This table can be extended according to the development of the protocol, and the embodiments of this application do not make any restrictions.

[0118] 4. PDCCH Reception
[0119] In the PDCCH monitoring work, the two factors that have a relatively large impact on the implementation complexity can include the following. One is the number of PDCCH candidates to be monitored, sometimes also referred to as the number of blind detections (BD); the other is the number of non-overlapping CCEs, sometimes simply referred to as the number of CCEs. The more PDCCH candidates to be monitored, the higher the decoding complexity of the terminal device; the more non-overlapping CCEs, the higher the channel estimation complexity of the terminal device. Among them, CCEs that satisfy different CORESET serial numbers and different starting symbols of the corresponding PDCCH candidates are considered non-overlapping.
[0120] There are the following 4 issues regarding PDCCH detection:
[0121] 1) Limitations: To reduce the complexity of the terminal device, in NR, upper limits are respectively imposed on the number of monitored PDCCH candidates and the number of non-overlapping CCEs. In R15, the limitation is applied per slot, and in R16, it is applied per span. Here, a span is a number of consecutive OFDM symbols within a slot.
[0122] 2) PDCCH candidate monitoring capabilities and allocation of the terminal device: Different terminal devices have different PDCCH candidate monitoring capabilities. The number of PDCCH candidates that a terminal device can support simultaneously and the number of non-overlapping CCEs are limited, which can be converted into the number of supported cells M. When the terminal device is configured with N cells but M < N, it is necessary to allocate the capabilities of the M cells that the terminal device can support to the N cells.
[0123] 3) Overbooking and handling: The PDCCH configuration of the network-side device may result in the number of monitored PDCCH candidates and the number of non-overlapping CCEs in some slots / spans being greater than the PDCCH candidate monitoring capabilities of the terminal device. In this case, the terminal device needs to select some PDCCH candidates in this slot / span for monitoring according to the protocol regulations to ensure that the number of monitored PDCCH candidates and the number of non-overlapping CCEs are less than or equal to the PDCCH candidate monitoring capabilities of the terminal device.
[0124] 4) Scenarios: Currently, the working scenarios defined by the 3rd generation partnership project (3GPP) protocol are:
[0125] R15 single cell / CA without multi-TRP;
[0126] R15 single cell / CA with multi-TRP;
[0127] R15 single cell / CA without multi-TRP and single cell / CA with multi-TRP;
[0128] R15 NR-DC without multi-TRP;
[0129] R16 single cell / CA without multi-TRP;
[0130] R15+R16 CA without multi-TRP;
[0131] The issue of allocating the PDCCH candidate monitoring capabilities of the terminal device needs to be discussed in different working scenarios. The embodiments of this application do not limit the working scenarios.
[0132] Among them, if the terminal device is configured with an SCG, the above method can be applied to both the MCG and the SCG. However, PDCCH detection on Type0 / 0A / 2-PDCCH CSS sets is not performed on the SCG (that is, SIB and paging are not received on the SCG). When applied to the MCG, "secondary cell SCell" and "serving cell" are used to represent the secondary cell and the serving cell in the MCG, and "primary cell PCell" is used to represent the PCell in the MCG; when applied to the SCG, "secondary cell SCell" and "serving cell" are used to represent the secondary cell and the serving cell in the SCG, and "primary cell PCell" is used to represent the PSCell in the SCG.

[0134] Differences between R15 and R16: In R15, the number of PDCCH candidates monitored on each slot and the number of non-overlapping CCEs are restricted, while in R16, a scheme restricted by each span is introduced.
[0135] The network device configures PDCCH monitoring capability configuration (PDCCHMonitoring Capability Config) for each serving cell of the terminal device. This parameter can have two values, namely R15 PDCCH monitoring capability and R16 PDCCH monitoring capability.
[0136] If the value of PDCCH Monitoring Capability Config for a serving cell is R15 PDCCH monitoring capability, or if PDCCH Monitoring Capability Config is not configured, the maximum number of PDCCH candidates and non-overlapping CCEs monitored by the terminal device on each slot in this serving cell is shown in Tables 2-1 and 2-3.
[0137] If the value of PDCCH Monitoring Capability Config for a serving cell is R16 PDCCH monitoring capability, the maximum number of PDCCH candidates and non-overlapping CCEs monitored by the terminal device on each span in this serving cell is shown in Tables 2-2 and 2-4, where values such as M01 and C01 can be determined according to the subsequent development of the protocol.

[0152] The resource scheduling method provided by embodiments of this application will be introduced below in conjunction with the accompanying drawings. It should be noted that, during the introduction process, the names of the information or data exchanged between the terminal device and the network device are for illustration purposes only and do not constitute a limitation on the embodiments of this application.
[0153] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of a resource scheduling method provided by an embodiment of this application. As Figure 2 shown, the resource scheduling method includes but is not limited to the following steps.
[0154] 201. The network-side device sends first configuration information to the terminal device;
[0155] 202. The terminal device receives the first configuration information sent by the network-side device.
[0156] Among them, the first configuration information is used to configure the resource location of the Physical Downlink Control Channel (PDCCH) candidates of the first cell. The Downlink Control Information (DCI) of the second cell is carried on at least one of the configured PDCCH candidates of the first cell. The DCI of the second cell is used to schedule the resource location for the terminal device to perform data communication on the second cell. Exemplarily, the resource location for data communication can be the resource location of the Physical Downlink Shared Channel (PDSCH) or the resource of the Physical Uplink Shared Channel (PUSCH). And the first cell and the second cell belong to the same cell group. The first cell and the second cell can be secondary cells or primary cells, which are not limited in the embodiments of this application and include but are not limited to the following possible scheduling scenarios.
[0157] Scenario 1, the first cell is a secondary cell in a cell group, and the second cell is the primary cell in the cell group. Herein, the cell group may include an MCG and an SCG. When the cell group is an MCG, the primary cell is the PCell in the MCG, and the secondary cell is any SCell in the MCG. Then, the first configuration information is used to configure the resource location of the PDCCH candidates of the SCell. The DCI of the PCell is carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the SCell. The DCI of the PCell is used to schedule the resource location for the terminal device to perform data communication on the PCell. Therefore, it is possible to implement scheduling of resources in the PCell using the SCell.
[0158] When the cell group is an SCG, the primary cell is the PSCell in the SCG, and the secondary cell is any SCell in the SCG. Then, the first configuration information is used to configure the resource location of the PDCCH candidates of the SCell. The DCI of the PSCell is carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the SCell. The DCI of the PSCell is used to schedule the resource location for the terminal device to perform data communication on the PSCell. Therefore, it is possible to implement scheduling of resources in the PSCell using the SCell.
[0159] Scenario 2, the first cell is a secondary cell in a cell group, and the second cell is another secondary cell in the cell group. Herein, the cell group may include an MCG and an SCG, and the secondary cell represents any SCell in the MCG or the SCG. For example, the first configuration information is used to configure the resource location of the PDCCH candidates of the SCell 1 The DCI of the SCell can be carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the SCell 2 The DCI of the SCell is used to schedule the resource location for the terminal device to perform data communication on the SCell 1 The DCI of the SCell is carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the SCell 2 The DCI of the SCell is used to schedule the resource location for the terminal device to perform data communication on the SCell 2 Therefore, it is possible to implement scheduling of resources in the SCell using the SCell.
[0160] Scenario 3, the first cell is the primary cell in a cell group, and the second cell is a secondary cell in the cell group. Herein, the cell group may include an MCG and an SCG. When the cell group is an MCG, the primary cell is the PCell in the MCG, and the secondary cell is any SCell in the MCG. Then, the first configuration information is used to configure the resource location of the PDCCH candidates of the PCell. The DCI of the SCell is carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the PCell. The DCI of the SCell is used to schedule the resource location for the terminal device to perform data communication on the SCell.
[0161] When the cell group is an SCG, the primary cell is the PSCell in the SCG, and the secondary cell is any SCell in the SCG. Then the first configuration information is used to configure the resource location of the PDCCH candidates of the PSCell, and the DCI of the SCell is carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the PSCell. The DCI of the SCell is used to schedule the resource location for the terminal device to perform data communication on the SCell.
[0162] Optionally, the network device also sends second configuration information to the terminal device. Correspondingly, the terminal device also receives the second configuration information sent by the network device. The second configuration information is used to configure the resource location of the PDCCH candidates of the second cell, and the downlink control information DCI of the second cell is carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the second cell.
[0163] Wherein, when the second cell is the PCell in Scenario 1 of the above scheduling scenario, the DCI of the PCell is carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the SCell, and / or carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the PCell. Therefore, it is possible to use the PCell and the SCell to schedule the resources of the PCell. When the second cell is the PSCell in Scenario 1 of the above scheduling scenario, the DCI of the PSCell is carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the SCell, and / or carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the PSCell. Therefore, it is possible to use the PSCell and the SCell to schedule the resources of the PSCell. When the second cell is the SCell of the MCG in Scenario 2 of the above scheduling scenario, the DCI of the SCell is carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the PCell, and / or carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the SCell. Therefore, it is possible to use the PCell and the SCell to schedule the resources of the SCell. When the second cell is the SCell of the SCG in Scenario 3 of the above scheduling scenario, the DCI of the SCell is carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the PSCell, and / or carried on at least one of the PDCCH candidates configured for the PDCCH candidates of the SCell. Therefore, it is possible to use the PSCell and the SCell to schedule the resources of the SCell. By using the secondary cell and the primary cell to schedule the primary cell or other secondary cells, the scheduling load of the network device is balanced.
[0164] Optionally, based on the above scheduling scenarios, the first configuration information can also be used to configure a search space set (SS set); and / or, the first configuration information can also be used to configure a Radio Network Temporary Identifier (RNTI), including but not limited to the following scheduling schemes.
[0165] Scheme 1: The first configuration information can also be used to configure a first SS set on a first cell. There is at least one Physical Downlink Control Channel (PDCCH) candidate in the first SS set for carrying the Downlink Control Information (DCI) of a second cell. When the cell group is a Master Cell Group (MCG), the first cell is at least one Secondary Cell (Scell) in the cell group, and the second cell is the Primary Cell (PCell) in the cell group, the first SS set does not belong to the Type0-PDCCH CSS set, Type0A-PDCCH CSS set, Type1-PDCCH CSS set, and Type2-PDCCH CSS set; and / or, when the cell group is a Secondary Cell Group (SCG), the first cell is at least one Scell in the cell group, and the second cell is the Primary and Secondary Cell (PScell) in the cell group, the first SS set does not belong to the Type1-PDCCH CSS set and Type2-PDCCH CSS set. Among them, the first SS set can be a Unique SS (USS).
[0166] The first configuration information is also used to configure a first RNTI, which is used to scramble the Cyclic Redundancy Check (CRC) of the DCI of the second cell carried in at least one PDCCH candidate of the first cell. When the cell group is an MCG, the first cell is at least one Scell in the cell group, and the second cell is the PCell in the cell group, the first RNTI does not belong to the SI-RNTI, P-RNTI, RA-RNTI, and TC-RNTI; and / or, when the cell group is an SCG, the first cell is at least one Scell in the cell group, and the second cell is the PScell in the cell group, the first RNTI does not belong to the RA-RNTI and TC-RNTI. Exemplarily, the first RNTI can be one of the C-RNTI, MCS-C-RNTI, and CS-RNTI.
[0167] Exemplarily, please refer to Figure 3 , Figure 3 which is a schematic diagram of the scenario of a scheduling scheme provided by an embodiment of this application. As Figure 3As shown in the figure, taking one primary cell group and one secondary cell group as an example for elaboration. Among them, the MCG includes one PCell and one SCell; the SCG includes one PSCell and one SCell. When the cell group is the MCG, the RNTI that scrambles the CRC of the DCI of the PCell carried in at least one PDCCH candidate of the SCell does not belong to SI-RNTI, P-RNTI, RA-RNTI, and TC-RNTI. That is, the PDCCH candidate whose CRC of the DCI of the PCell is scrambled with SI-RNTI, P-RNTI, RA-RNTI, or TC-RNTI cannot be configured on the SCell; the PDCCH candidate whose CRC of the DCI of the PCell is scrambled with an RNTI other than SI-RNTI, P-RNTI, RA-RNTI, or TC-RNTI is configured on the SCell. When the cell group is the SCG, the RNTI that scrambles the CRC of the DCI of the PSCell carried in at least one PDCCH candidate of the SCell does not belong to RA-RNTI and TC-RNTI; that is, the PDCCH candidate whose CRC of the DCI of the PSCell can be scrambled with RA-RNTI or TC-RNTI cannot be configured on the SCell; the PDCCH candidate whose CRC of the DCI of the PCell is scrambled with an RNTI other than RA-RNTI or TC-RNTI is configured on the SCell.
[0168] Carry the DCI related to some non-broadcast channels of the PCell or PSCell, such as the DCI related to single-point transmission, on the PDCCH candidate in the SCell. This improves the scheduling flexibility and saves the scheduling resources on the PCell and PSCell.
[0169] Solution 2: The first configuration information can also be used to configure the first SS set on the first cell, and there is at least one PDCCH candidate in the first SS set for carrying the DCI of the second cell; when the cell group is the primary cell group MCG, the first cell is at least one secondary cell Scell in the cell group, and the second cell is the primary cell PCell in the cell group, the first SS set does not belong to Type0-PDCCH CSS set, Type0A-PDCCH CSS set, Type1-PDCCH CSS set, and Type2-PDCCH CSS set; and / or, when the cell group is the secondary cell group SCG, the first cell is at least one secondary cell Scell in the cell group, and the second cell is the primary and secondary cell PSCell in the cell group, the first SS set does not belong to Type1-PDCCH CSS set and Type2-PDCCH CSS set. Among them, the first SS set can be the USS.
[0170] Optionally, the first configuration information is further used to configure a first RNTI, which is used to scramble the cyclic redundancy check (CRC) of the DCI of the second cell carried in at least one PDCCH candidate of the first cell; when the cell group is the master cell group (MCG), the first cell is at least one secondary cell (Scell) in the cell group, and the second cell is the primary cell (PCell) in the cell group, the first RNTI does not belong to SI-RNTI, P-RNTI, RA-RNTI, and TC-RNTI; and / or when the cell group is the secondary cell group (SCG), the first cell is at least one Scell in the cell group, and the second cell is the primary and secondary cell (PSCell) in the cell group, the first RNTI does not belong to RA-RNTI and TC-RNTI. Exemplarily, the first RNTI may be one of C-RNTI, MCS-C-RNTI, and CS-RNTI.
[0171] Optionally, the second configuration information may further be used to configure a second SS set on the second cell, and there is at least one PDCCH candidate in the second SS set for carrying the DCI of the second cell; when the cell group is MCG, the first cell is at least one Scell in the cell group, and the second cell is the PCell in the cell group, the second SS set belongs to at least one of Type0-PDCCH CSS set, Type0A-PDCCH CSS set, Type1-PDCCH CSS set, and Type2-PDCCH CSS set; and / or when the cell group is SCG, the first cell is at least one Scell in the cell group, and the second cell is the PScell in the cell group, the second SS set belongs to at least one of Type1-PDCCH CSS set and Type2-PDCCH CSS set.
[0172] Optionally, the second configuration information is further used to configure a second RNTI, which is used to scramble the CRC of the DCI of the second cell carried on at least one PDCCH candidate of the second cell; when the cell group is MCG, the first cell is at least one Scell in the cell group, and the second cell is the PCell in the cell group, the second RNTI belongs to at least one of SI-RNTI, P-RNTI, RA-RNTI, and TC-RNTI; and / or when the cell group is SCG, the first cell is at least one Scell in the cell group, and the second cell is the PSCell in the cell group, the second RNTI belongs to at least one of RA-RNTI and TC-RNTI.
[0173] Exemplarily, please refer to Figure 4 , Figure 4This is a scenario schematic diagram of another scheduling scheme provided by an embodiment of the present application. As Figure 4 shown, taking one master cell group and one secondary cell group as an example for illustration. Among them, the MCG includes one PCell and one SCell; the SCG includes one PSCell and one SCell. When the cell group is the MCG, the RNTI scrambling the CRC of the DCI of the PCell carried in at least one PDCCH candidate of the SCell does not belong to SI-RNTI, P-RNTI, RA-RNTI, and TC-RNTI, and the RNTI scrambling the CRC of the DCI of the PCell carried in at least one PDCCH candidate of the PCell belongs to at least one of SI-RNTI, P-RNTI, RA-RNTI, and TC-RNTI. That is, the PDCCH candidate whose CRC of the DCI of the PCell is scrambled with SI-RNTI, P-RNTI, RA-RNTI, or TC-RNTI cannot be configured on the SCell and can only be configured on the PCell; the PDCCH candidate whose CRC of the DCI of the PCell is scrambled with an RNTI other than SI-RNTI, P-RNTI, RA-RNTI, or TC-RNTI is configured on the SCell. When the cell group is the SCG, the RNTI scrambling the CRC of the DCI of the PSCell carried in at least one PDCCH candidate of the SCell does not belong to RA-RNTI and TC-RNTI, and the RNTI scrambling the CRC of the DCI of the PSCell carried in at least one PDCCH candidate of the PSCell belongs to at least one of RA-RNTI and TC-RNTI; that is, the PDCCH candidate whose CRC of the DCI of the PSCell can be scrambled with RA-RNTI and TC-RNTI cannot be configured on the SCell and can only be configured on the PSCell; the PDCCH candidate whose CRC of the DCI of the PCell is scrambled with an RNTI other than RA-RNTI or TC-RNTI is configured on the SCell.
[0174] The DCI related to the broadcast channel of the PCell or PSCell can be carried on the PDCCH candidate in the PCell or PSCell; the DCI related to the non-broadcast channel is carried on the PDCCH candidate in the SCell. This improves the scheduling flexibility, saves the scheduling resources on the PCell and PSCell, and balances the load of the network-side device.
[0175] Solution 3. The first configuration information can also be used to configure a first SS set on the first cell, where there is at least one PDCCH candidate in the first SS set for carrying the DCI of the second cell; when the cell group is the master cell group MCG, the first cell is at least one secondary cell Scell in the cell group, and the second cell is the primary cell PCell in the cell group, the first SS set does not belong to the Type0-PDCCH CSS set, the Type0A-PDCCH CSS set, the Type1-PDCCH CSS set, and the Type2-PDCCH CSS set; and / or when the cell group is the secondary cell group SCG, the first cell is at least one secondary cell Scell in the cell group, and the second cell is the primary and secondary cell PScell in the cell group, the first SS set does not belong to the Type1-PDCCH CSS set and the Type2-PDCCH CSS set. Wherein, the first SS set may be a USS.
[0176] Optionally, the first configuration information is further used to configure a first RNTI, and the first RNTI is used to scramble the cyclic redundancy check CRC of the DCI of the second cell carried in at least one PDCCH candidate of the first cell; when the cell group is the master cell group MCG, the first cell is at least one secondary cell Scell in the cell group, and the second cell is the primary cell PCell in the cell group, the first RNTI does not belong to the SI-RNTI, the P-RNTI, the RA-RNTI, and the TC-RNTI; and / or when the cell group is the secondary cell group SCG, the first cell is at least one secondary cell Scell in the cell group, and the second cell is the primary and secondary cell PSCell in the cell group, the first RNTI does not belong to the RA-RNTI and the TC-RNTI. Exemplarily, the first RNTI may be one of the C-RNTI, the MCS-C-RNTI, and the CS-RNTI.
[0177] If the first cell is a secondary cell in the cell group and the second cell is the primary cell in the cell group, the first configuration information further satisfies that all PDCCH candidates capable of carrying the DCI of the second cell are on the first cell. And the network side device cannot send the second configuration information to the terminal device any more.
[0178] Exemplarily, please refer to Figure 5 , Figure 5 which is a schematic diagram of the scenario of another scheduling solution provided by the embodiments of the present application. As Figure 5As shown in the figure, taking one master cell group and one secondary cell group as an example for illustration. Among them, the MCG includes one PCell and one SCell; the SCG includes one PSCell and one SCell. When the cell group is the MCG, the RNTI that scrambles the CRC of the DCI of the PCell carried in at least one PDCCH candidate of the SCell does not belong to SI-RNTI, P-RNTI, RA-RNTI, and TC-RNTI. That is, the PDCCH candidate whose CRC of the DCI of the PCell is scrambled by SI-RNTI, P-RNTI, RA-RNTI, or TC-RNTI cannot be configured on the SCell; the PDCCH candidate whose CRC of the DCI of the PCell is scrambled by an RNTI other than SI-RNTI, P-RNTI, RA-RNTI, or TC-RNTI can only be configured on the SCell; the DCI of the PCell cannot be carried in the PDCCH candidate of the PCell. When the cell group is the SCG, the RNTI that scrambles the CRC of the DCI of the PSCell carried in at least one PDCCH candidate of the SCell does not belong to RA-RNTI and TC-RNTI. That is, the PDCCH candidate whose CRC of the DCI of the PSCell is scrambled by RA-RNTI or TC-RNTI cannot be configured on the SCell; the PDCCH candidate whose CRC of the DCI of the PCell is scrambled by an RNTI other than RA-RNTI and TC-RNTI can only be configured on the SCell; the DCI of the PSCell cannot be carried in the PDCCH candidate of the PCell.
[0179] Carry the DCI related to the non-broadcast channel of the PCell or PSCell on the PDCCH candidate in the SCell. This improves the scheduling flexibility, saves the scheduling resources on the PCell and PSCell, and the terminal device does not need to receive the PDCCH on the PCell and PSCell, saving the power consumption of the terminal device.
[0180] Solution 4: The first configuration information can also be used to configure a first SS set on the first cell. There is at least one PDCCH candidate in the first SS set for carrying the DCI of the second cell. When the cell group is MCG, the first cell is at least one Scell in the cell group, and the second cell is the PCell in the cell group, the first SS set belongs to at least one of Type0-PDCCH CSSset, Type0A-PDCCH CSS set, Type1-PDCCH CSS set, and Type2-PDCCH CSS set; and / or when the cell group is SCG, the first cell is at least one Scell in the cell group, and the second cell is the PScell in the cell group, the first SS set belongs to at least one of Type1-PDCCH CSS set and Type2-PDCCH CSS set.
[0181] Optionally, the first configuration information is further used to configure a first RNTI, and the first RNTI is used to scramble the cyclic redundancy check CRC of the DCI of the second cell carried in at least one PDCCH candidate of the first cell. When the cell group is MCG, the first cell is at least one Scell in the cell group, and the second cell is the PCell in the cell group, the first RNTI belongs to at least one of SI-RNTI, P-RNTI, RA-RNTI, and TC-RNTI; and / or when the cell group is SCG, the first cell is at least one Scell in the cell group, and the second cell is the PSCell in the cell group, the first RNTI belongs to at least one of RA-RNTI and TC-RNTI. Exemplarily, the first RNTI can also be one of C-RNTI, MCS-C-RNTI, and CS-RNTI.
[0182] If the first cell is a secondary cell in the cell group and the second cell is the primary cell in the cell group. Optionally, the first configuration information further satisfies the following principle: all PDCCH candidates capable of carrying the DCI of the second cell are on the first cell, and the network-side device cannot send the second configuration information to the terminal device anymore.
[0183] Exemplarily, please refer to Figure 6 , Figure 6 which is a schematic diagram of a scheduling solution scenario provided by an embodiment of this application. As Figure 6As shown, taking one primary cell group and one secondary cell group as an example for illustration. Among them, the MCG includes one PCell and one SCell; the SCG includes one PSCell and one SCell. When the cell group is the MCG, the RNTI that scrambles the CRC of the DCI of the PCell carried in at least one PDCCH candidate of the SCell belongs to at least one of SI-RNTI, P-RNTI, RA-RNTI, and TC-RNTI. That is, the PDCCH candidate whose CRC of the DCI of the PCell is scrambled by SI-RNTI, P-RNTI, RA-RNTI, or TC-RNTI can only be configured on the SCell; the PDCCH candidate whose CRC of the DCI of the PCell is scrambled by an RNTI other than SI-RNTI, P-RNTI, RA-RNTI, or TC-RNTI can also only be configured on the SCell; the DCI of the PCell cannot be carried in the PDCCH candidate of the PCell. When the cell group is the SCG, the RNTI that scrambles the CRC of the DCI of the PSCell carried in at least one PDCCH candidate of the SCell belongs to at least one of RA-RNTI and TC-RNTI. That is, the PDCCH candidate whose CRC of the DCI of the PSCell is scrambled by RA-RNTI or TC-RNTI can only be configured on the SCell; the PDCCH candidate whose CRC of the DCI of the PCell is scrambled by an RNTI other than RA-RNTI and TC-RNTI can also only be configured on the SCell; the DCI of the PSCell cannot be carried in the PDCCH candidate of the PCell.
[0184] All DCIs are carried on the PDCCH candidates of the SCell. This improves the scheduling flexibility, saves the scheduling resources on the PCell and the PSCell, and the terminal device does not need to receive the PDCCH on the PCell and the PSCell, saving the power consumption of the terminal device.
[0185] Based on Scheme 3 or Scheme 4 in the above scheduling scheme, when the first configuration information is used to configure the resource position of the PDCCH candidate of the first cell, the following several rules are also satisfied.
[0186] In a possible implementation, the number of PDCCH candidates carrying the DCI of the second cell configured in any unit time on the first cell is less than or equal to the PDCCH candidate monitoring capability of the terminal device, and / or, the number of non-overlapping control channel units related to the PDCCH candidates carrying the DCI of the second cell configured in any unit time on the first cell is less than or equal to the PDCCH candidate monitoring capability of the terminal device. Among them, in the R15 related working scenario, any unit time can be a slot, and in the R16 related working scenario, any unit time can be a span. The embodiments of the present application do not make restrictions. The PDCCH candidate monitoring capability of the terminal device can be determined by the relevant descriptions of steps 902-905 in the resource scheduling method shown by Figure 9 including the upper limit of the number of PDCCH candidates to be monitored and the upper limit of the number of non-overlapping control channel units
[0187] Exemplarily, when the SCell schedules the PCell, that is, only the DCI of the PCell is sent in the PDCCH candidates of the SCell to schedule the PDCCH candidates in the PCell. The PDCCH candidates configured by the network side device for the terminal device are guaranteed not to be overbooked. That is, the number of PDCCH candidates carrying the DCI related to the PCell configured on the SCell by the network side device is less than or equal to The number of non-overlapping CCEs is less than or equal to Based on this possible implementation, the working complexity of the terminal device when determining the PDCCH candidates to be monitored is reduced.
[0188] In an implementation, the number of PDCCH candidates carrying the DCI of the second cell configured in any unit time on the first cell is allowed to be greater than the PDCCH candidate monitoring capability of the terminal device, and / or, the number of non-overlapping control channel units related to the PDCCH candidates carrying the DCI of the second cell configured in any unit time on the first cell is allowed to be greater than the PDCCH candidate monitoring capability of the terminal device; that is, overbooking will occur. Based on this possible implementation, the flexibility of configuring the PDCCH is increased.
[0189] Optionally, the terminal device determines whether overbooking will occur according to the scheduling scheme. Among them, the protocol may stipulate that the scheduling scheme can only be one of the above scheduling schemes, or the protocol may stipulate that the scheduling scheme is several of the above scheduling schemes; the terminal device determines the specific scheduling scheme according to the PDCCH candidates configured by the network-side device. For example, when using the configuration scheme described in the above Scheme 3, overbooking may occur, that is, the number of PDCCH candidates related to the PCell on the configured SCell is allowed to be greater than the number of non-overlapping CCEs is allowed to be greater than For another example, when using the scheduling scheme described in Scheme 4, overbooking will not occur. That is, the number of PDCCH candidates related to the PCell on the configured SCell is less than the number of non-overlapping CCEs is less than Determining whether there is overbooking through the scheduling scheme reduces the complexity of the terminal device.
[0190] In a possible implementation manner, the protocol may stipulate that in the following scenarios, overbooking may occur on the USS of the SCell:
[0191] a) No PDCCHMonitoringCapabilityConfig is configured on the SCell, and overbooking occurs in the slot;
[0192] b) PDCCHMonitoringCapabilityConfig equal to R15 PDCCH monitoring capability is configured for all cells, and overbooking occurs in the slot;
[0193] c) PDCCHMonitoringCapabilityConfig equal to R16 PDCCH monitoring capability is configured on the SCell, and overbooking occurs in the span;
[0194] d) On the USS of the SCell, the first set of CORESET is not configured with CORESETPoolIndex, or the first set of CORESET is configured with CORESETPoolIndex as 0, and the second set of CORESET is configured with CORESETPoolIndex as 1.
[0195] e) If
[0196] Or, Then overbooking will only occur on the USS corresponding to the first set of CORESETs.
[0197] Optionally, after overbooking occurs, the terminal device further performs the following steps. First, subtract the number of PDCCH candidates associated with the CSS used for monitoring / the number of non-overlapping CCEs from the upper limit of the number of PDCCH candidates monitored within 1 slot / span / the upper limit of the number of non-overlapping CCEs within 1 slot, respectively, to obtain the remaining total number of PDCCH candidates and the remaining total number of non-overlapping CCEs
[0198] For the USS, according to the priority order of the search space, starting from the highest priority, subtract from and the number of PDCCH candidates associated with each search space monitored / the number of non-overlapping CCEs, respectively. If for a certain USS index value, the remaining total number of PDCCH candidates / non-overlapping CCEs after subtraction is still greater than or equal to 0; then the terminal device needs to monitor the PDCCH candidates corresponding to this USS index value. If for a certain USS index value, at least one of the remaining total number of PDCCH candidates / non-overlapping CCEs after subtraction is less than 0; then the terminal device does not need to monitor the PDCCH candidates corresponding to this USS index value and the search spaces with larger USS index values than this one.
[0199] Based on Scheme 1 or Scheme 2 in the above configuration scheme, when the first configuration information is used to configure the resource location of the PDCCH candidates of the downlink control channel of the first cell, the following several rules are also satisfied.
[0200] In one implementation, the number of PDCCH candidates carrying the DCI of the second cell configured at any unit time on the first cell is allowed to be greater than the PDCCH candidate monitoring capability of the terminal device, and / or, the number of non-overlapping control channel elements related to the PDCCH candidates carrying the DCI of the second cell configured at any unit time on the first cell is allowed to be greater than the PDCCH candidate monitoring capability of the terminal device; and / or, the number of PDCCH candidates carrying the DCI of the second cell configured at any unit time on the second cell is allowed to be greater than the PDCCH candidate monitoring capability of the terminal device, and / or, the number of non-overlapping control channel elements related to the PDCCH candidates carrying the DCI of the second cell configured at any unit time on the second cell is allowed to be greater than the PDCCH candidate monitoring capability of the terminal device. Based on this possible implementation, the flexibility of configuring the PDCCH is increased.
[0201] In one implementation, the sum of the number of PDCCH candidates carrying the DCI of the second cell configured in any unit time on the first cell and the number of PDCCH candidates carrying the DCI of the second cell configured in any unit time on the second cell is allowed to be greater than the PDCCH candidate monitoring capability of the terminal device, and / or, the sum of the number of non-overlapping control channel elements related to the PDCCH candidates carrying the DCI of the second cell configured in any unit time on the first cell and the number of non-overlapping control channel elements related to the PDCCH candidates carrying the DCI of the second cell configured in any unit time on the second cell is allowed to be greater than the PDCCH candidate monitoring capability of the terminal device. Based on this possible implementation, the flexibility of configuring the PDCCH is increased.
[0202] Among them, in any unit time in the R15-related working scenario, it can be a slot, and in any unit time in the R16-related working scenario, it can be a span. The embodiments of this application do not make any restrictions. The PDCCH candidate monitoring capability of the terminal device can be determined by the relevant descriptions in steps 902-905 of the resource scheduling method shown in Figure 9 or determined by the relevant description in step 701 of the resource scheduling method shown in Figure 7 or determined by the relevant description in step 801 of the resource scheduling method shown in Figure 8 , which will not be elaborated here. The PDCCH candidate monitoring capability of the terminal device includes the upper limit of the number of monitored PDCCH candidates and the upper limit of the number of non-overlapping control channel elements
[0203] Optionally, based on any one of Solutions 1 to 4 in the above scheduling solution, the terminal device further performs the following steps.
[0204] The terminal device receives first indication information sent by the network-side device; wherein, if the first indication information indicates a first value, the first indication information indicates that the number of PDCCH candidates carrying DCI of the second cell configured per unit time on the first cell is less than or equal to the PDCCH candidate monitoring capability of the terminal device, and / or, the number of non-overlapping control channel units related to the PDCCH candidates carrying DCI of the second cell configured per unit time on the first cell is less than or equal to the PDCCH candidate monitoring capability of the terminal device; if the first indication information indicates a second value, the first indication information indicates that the number of PDCCH candidates carrying DCI of the second cell configured per unit time on the first cell is allowed to be greater than the PDCCH candidate monitoring capability of the terminal device, and / or, the number of non-overlapping control channel units related to the PDCCH candidates carrying DCI of the second cell configured per unit time on the first cell is allowed to be greater than the PDCCH candidate monitoring capability of the terminal device. Wherein, in the R15 related working scenario, the per unit time can be a slot, and in the R16 related working scenario, the per unit time can be a span, which is not limited in the embodiments of the present application. The specific values of the first value and the second value are not limited. For example, the first value is 0 and the second value is 1. The PDCCH candidate monitoring capability of the terminal device can be determined by the relevant descriptions in steps 902-905 of the resource scheduling method shown in Figure 9 or determined by the relevant description in step 701 of the resource scheduling method shown in Figure 7 or determined by the relevant description in step 801 of the resource scheduling method shown in Figure 8 which will not be elaborated here. The PDCCH candidate monitoring capability of the terminal device includes the upper limit of the number of monitored PDCCH candidates and the upper limit of the number of non-overlapping control channel units
[0205] Optionally, if the protocol stipulates the existence of the first indication information and the network-side device does not send the first indication information to the terminal device, the terminal device determines its indication default value. Wherein, the default value can be the first value or the second value; for example, the default indicates the second value. Based on this possible implementation, the working complexity of the terminal device is reduced and the flexibility of configuring the PDCCH is increased.
[0206] Optionally, based on Scheme 1 or Scheme 2 in the above scheduling scheme, the terminal device further performs the following steps.
[0207] The terminal device receives second indication information sent by the network - side device; wherein, if the second indication information indicates a first value, the second indication information indicates that the sum of the number of PDCCH candidates carrying DCI of the second cell configured per unit time on the first cell and the number of PDCCH candidates carrying DCI of the second cell configured per unit time on the second cell is less than or equal to the PDCCH candidate monitoring capability of the terminal device, and / or, the sum of the number of non - overlapping control channel units related to the PDCCH candidates carrying DCI of the second cell configured per unit time on the first cell and the number of non - overlapping control channel units related to the PDCCH candidates carrying DCI of the second cell configured per unit time on the second cell is less than or equal to the PDCCH candidate monitoring capability of the terminal device; if the second indication information indicates a second value, the first indication information indicates that the sum of the number of PDCCH candidates carrying DCI of the second cell configured per unit time on the first cell and the number of PDCCH candidates carrying DCI of the second cell configured per unit time on the second cell is allowed to be greater than the PDCCH candidate monitoring capability of the terminal device, and / or, the sum of the number of non - overlapping control channel units related to the PDCCH candidates carrying DCI of the second cell configured per unit time on the first cell and the number of non - overlapping control channel units related to the PDCCH candidates carrying DCI of the second cell configured per unit time on the second cell is allowed to be greater than the PDCCH candidate monitoring capability of the terminal device.
[0208] Among them, in the R15 - related working scenario, the unit time can be a slot, and in the R16 - related working scenario, the unit time can be a span. The embodiments of this application do not make restrictions. The specific values of the first value and the second value are not restricted. For example, the first value is 0 and the second value is 1. The PDCCH candidate monitoring capability of the terminal device can be determined by the relevant descriptions in steps 902 - 905 of the resource scheduling method shown in Figure 9 or determined by the relevant description in step 701 of the resource scheduling method shown in Figure 7 or determined by the relevant description in step 801 of the resource scheduling method shown in Figure 8 , which will not be elaborated here. The PDCCH candidate monitoring capability of the terminal device includes the upper limit of the number of monitored PDCCH candidates and the upper limit of the number of non - overlapping control channel units
[0209] Optionally, if the protocol stipulates the existence of the first indication information and the network - side device does not send the first indication information to the terminal device, the terminal device determines that it indicates the default value. Among them, the default value can be the first value or the second value; for example, the default indicates the second value. Based on this possible implementation method, the working complexity of the terminal device is reduced, and the flexibility of configuring the PDCCH is increased.
[0210] In the embodiments of the present application, the network side device configures the resource location of the physical downlink control channel (PDCCH) candidates of the first cell for the terminal device. The downlink control information (DCI) of the second cell is carried on at least one of the configured PDCCH candidates of the first cell, and the DCI of the second cell is used to schedule the resource location for the terminal device to perform data communication on the second cell. By implementing the embodiments of the present application, it is possible to implement scheduling resources in the primary cell using the secondary cell, thereby improving scheduling flexibility.
[0211] Please refer to Figure 7 , Figure 7 which is a schematic flowchart of another resource scheduling method proposed in the embodiments of the present application. Figure 7 The resource scheduling method shown can be combined with Figure 2 Scheme 1 or Scheme 2 in the scheduling scheme shown and used when the subcarrier spacings of the primary cell (PCell) and the secondary cell (SCell) are the same. As Figure 7 shown, the resource scheduling method includes but is not limited to the following steps.
[0212] 701. The network side device sends first parameter information to the terminal device;
[0213] 702. The terminal device receives the first parameter information sent by the network side device; the first parameter information is used to configure the first cell and the second cell as r cells for PDCCH candidate monitoring capability allocation. Here, r is a positive number, and the value of r can be a non-integer such as 1.5.
[0214] Optionally, before receiving the first configuration parameter sent by the network side device, the terminal device also performs the following steps:
[0215] The terminal device reports capability information to the network side device, or does not report capability information when the capability parameter is a preset value; correspondingly, the network side device determines the capability parameter R according to the report of the terminal device, or determines the capability parameter R according to the preset value; R is used to determine r, and the value of r is less than or equal to the capability parameter R of the terminal device. Optionally, the protocol stipulates that the terminal device reports capability information. If the terminal device does not report, the network side device defaults R = 1. If the protocol does not stipulate that the terminal device can report R, the network side device determines R = 1.
[0216] Exemplarily, when the PCell and the SCell schedule the PCell, the terminal device reports R. If R = 1, it indicates that the terminal device has the ability to map the PCell and the SCell to one cell; if R = 2, it indicates that the terminal device has the ability to map the PCell and the SCell to two cells. If the terminal device does not report, the network device determines that R = 1; or, if the protocol does not specify that the terminal device can report R, the network device determines that R = 1; R = 1 indicates that the terminal device has the ability to map the PCell and the SCell to one cell.
[0217] Optionally, when allocating the PDCCH candidate monitoring capability, the PDCCH candidate monitoring capability of the terminal device can also be preset by the protocol, including but not limited to the following possible implementation manners.
[0218] In a possible implementation, the protocol presets that the terminal device allocates the PDCCH candidate monitoring capability for the first cell and the second cell as r cells, where r is a positive number, for example, r is 1 or 2.
[0219] In a possible implementation, the protocol presets that the terminal device allocates the PDCCH candidate monitoring capability for the first cell as r 1 cells; and for the second cell as r 2 cells. Here, r 1 and r 2 are positive numbers, and they can be the same or different. For example, r 1 is 1, and r 2 is 1.
[0220] In a possible implementation, when the subcarrier spacings of the downlink active BWPs of the first cell and the second cell are the same, the protocol presets that the terminal device allocates the PDCCH candidate monitoring capability for the first cell and the second cell as r cells, where r is a positive number, for example, r is 1 or 2.
[0221] The PCell and the SCell are allocated the PDCCH candidate monitoring capability as r cells; when the PCell schedules itself, it is allocated the PDCCH candidate monitoring capability as r 1 cells; when the SCell schedules the PCell, it is allocated the PDCCH candidate monitoring capability as r 2 cells. Here, r 1 + r 2 = r, and the value of r is less than R, for example, 1 < r < R. For example, when R = 2, r can be 1.5.
[0222] When allocating the PDCCH candidate monitoring capability, the PCell scheduled by the PCell and SCell is used as r cells, and the PCell and SCell scheduling the PCell are used as r cells. Specifically, when allocating the PDCCH candidate monitoring capability, it is implemented in combination with steps 904 and 905 in the resource scheduling method shown in Figure 9 Among them, the cells with the same subcarrier spacing are grouped together, and according to the proportion of the number of cells in this group in the total number of cells, the corresponding PDCCH candidate monitoring capability is allocated from the total PDCCH candidate monitoring capability of the terminal device, so as to obtain the upper limit of the number of PDCCH candidates and non-overlapping CCEs corresponding to this subcarrier spacing. Among them, when counting the cells with the same subcarrier spacing, the PCell scheduled by the PCell and SCell only accounts for one count. That is, if the PCell and SCell schedule the same cell, then the PCell and SCell only account for one count in Or Only account for one count. Assume that the number of PCells that can be scheduled by the PCell and SCell is Then the total number of cells participating in the PDCCH candidate monitoring capability allocation is And assume that there are no multi-TRP cells, that is, At this time, if there are 6 cells: 2 cells with a subcarrier spacing of 15K, 2 cells with a subcarrier spacing of 30k, 1 cell with a subcarrier spacing of 60K, and 1 cell with a subcarrier spacing of 120K. One of the cells with a subcarrier spacing of 15k is the PCell, and this PCell can be jointly scheduled by the PCell and SCell. This PCell is used as 1 cell, and then multiplied by the obtained r value. Assume that r is 1.5. The final total number of cells participating in the PDCCH candidate monitoring capability allocation is cells.
[0223] 703. The network side device sends the first configuration information to the terminal device;
[0224] 704. The terminal device receives the first configuration information sent by the network side device.
[0225] The specific implementation manners of step 703 and step 704 can refer to the description of the relevant steps shown in Figure 2 Here, it will not be elaborated.
[0226] Optionally, when the configured PDCCH candidates are allowed to be greater than the PDCCH candidate monitoring capability of the terminal device, that is, the number of PDCCH candidates carrying the DCI of the second cell configured in any unit time on the first cell is allowed to be greater than the PDCCH candidate monitoring capability of the terminal device, and / or, the number of non-overlapping control channel elements related to the PDCCH candidates carrying the DCI of the second cell configured in any unit time on the first cell is allowed to be greater than the PDCCH candidate monitoring capability of the terminal device; the terminal device also performs the Overbooking process. The Overbooking process mainly lies in determining the priority of the search spaces on the USS. For example, there may be search spaces for scheduling the PCell on the USSs of both the PCell and the SCell, so determining the priority will be relatively complex. Among them, the priority can be preset by the protocol in combination with the scheduling scheme, or configured by the network-side device. Determining the priority of the search spaces on the USS may include but is not limited to the following methods.
[0227] In one implementation, sort each search space in the terminal device USSs of the second cell and the first cell in the cell group including the PDCCH candidates that can be used to carry the downlink control information DCI of the second cell, and determine the priority of each search space in the PDCCH candidate monitoring capability allocation according to the sorting result.
[0228] Exemplarily, sort the search spaces of all the USSs of the PCell and the SCell. The index values of the search spaces that can schedule the PCell on the PCell and the SCell cannot be the same, so the priority can be determined by the index value of the search space. For example, the terminal device configures a cell A as the PCell and a cell B as the SCell. Assume that the index value of the search space in the USS of cell A is 0xx-100, and the index value of the search space in the USS of cell B is 101-1xx, then the smaller the index value, the higher the priority.
[0229] In one implementation, the terminal device determines the search space priorities of the first cell and the second cell in the cell group including the PDCCH candidates that can be used to carry the downlink control information DCI of the second cell.
[0230] a) The priorities of each search space in the terminal device dedicated search space USS of the first cell are all higher than the priorities of each search space in the USS of the second cell. Exemplarily, the protocol stipulates or the base station configures that the search space priority of the SCell is higher than that of the PCell, and the terminal device obtains that the priorities of all the search spaces of the SCell are higher than those of all the search spaces of the PCell according to the protocol.
[0231] b) The priorities of the search spaces in the UE-specific search space (USS) of the second cell are all higher than those of the search spaces in the USS of the first cell. Exemplarily, the protocol stipulates or the base station configures that the priority of the search space in the USS of the PCell is higher than that of the SCell. The UE obtains that the priorities of all search spaces in the USS of the PCell are higher than those of all search spaces in the USS of the SCell according to the protocol.
[0232] c) In the USS of the first cell and the second cell, the smaller the index value corresponding to the search space, the higher the priority of the search space. Among the search spaces with the same index value, the priority of the search space in the USS of the first cell is higher than that of the search space in the USS of the second cell. Exemplarily, the protocol stipulates or the base station configures that the index values of the search spaces in the USS of the SCell are 001, 002, 003... etc., and the index values of the search spaces in the USS of the PCell are 003, 005, 007... etc. Then the priorities of the search spaces 001 and 002 in the SCell are higher than those of the search spaces in the PCell. The priority of the search space 003 in the SCell is higher than that of the search space 003 in the PCell.
[0233] d) In the USS of the first cell and the second cell, the smaller the index value corresponding to the search space, the higher the priority of the search space. Among the search spaces with the same index value, the priority of the search space in the USS of the second cell is higher than that of the search space in the USS of the first cell. Exemplarily, the protocol stipulates or the base station configures that the index values of the search spaces in the USS of the SCell are 001, 002, 003... etc., and the index values of the search spaces in the USS of the PCell are 003, 005, 007... etc. Then the priorities of the search spaces 001 and 002 in the SCell are higher than those of the search spaces 003, 005, and 007 in the PCell. The priority of the search space 003 in the PCell is higher than that of the search space 003 in the SCell.
[0234] e) The search spaces in the USS belonging to the first cell and the search spaces in the USS belonging to the second cell, where the smaller the index value corresponding to the search space, the higher the priority of the search space. Among them, the network device will ensure that the index values of the search spaces in the USS belonging to the first cell and the search spaces in the USS belonging to the second cell that contain the PDCCH candidates that can carry the downlink control information DCI of the second cell are all different. Exemplarily, the protocol stipulates or the base station configures that the index values of the search spaces in the USS of the SCell cell are 001, 002, 003... etc., and the index values of the search spaces in the USS of the PCell cell cannot be 001, 002, 003... etc., and can be 101, 102, 103, etc. It can be ensured that the index values of the search spaces in the USS of the SCell and PCell cells are all different.
[0235] Optionally, the network device determines the PDCCH candidates that can send the DCI of the second cell among the configured PDCCH candidates according to the priority. Correspondingly, the terminal device determines the PDCCH candidates that need to be monitored among the configured PDCCH candidates according to the priority.
[0236] The terminal device first subtracts the number of PDCCH candidates associated with the CSS for listening / the number of non-overlapping CCEs from the upper limit of the number of PDCCH candidates listened to within 1 slot / span / the upper limit of the number of non-overlapping CCEs within 1 slot respectively, and obtains the remaining total number of PDCCH candidates and the remaining total number of non-overlapping CCEs
[0237] For the USS, according to the priority order of the obtained search spaces above, starting from the highest priority, from and subtract the number of PDCCH candidates associated with each search space for monitoring / the number of non-overlapping CCEs respectively. If for a certain USS index value, the remaining total number of PDCCH candidates / non-overlapping CCEs after subtraction is still greater than or equal to 0; then the network device can send the DCI of the second cell in the PDCCH candidates corresponding to this USS index value, and correspondingly, the terminal device needs to monitor the PDCCH candidates corresponding to this USS index value. If for a certain USS index value, at least one of the remaining total number of PDCCH candidates / non-overlapping CCEs after subtraction is less than 0; then the network device cannot send the DCI of the second cell in the PDCCH candidates corresponding to this USS index value and the search spaces with a larger USS index value than this USS index value, and correspondingly, the terminal device does not need to monitor the PDCCH candidates corresponding to this USS index value and the search spaces with a larger USS index value than this USS index value.
[0238] Figure 7The resource scheduling method shown is also applicable to the scenario where the PCell and SCell simultaneously schedule the SCell.
[0239] In the embodiments of the present application, the terminal device reports capability information to the network-side device. The network-side device determines the capability parameter R based on the report of the terminal device, and then determines r based on R. The network-side device configures the first cell and the second cell as r cells for PDCCH candidate monitoring capability allocation. By implementing the embodiments of the present application, when the subcarrier spacing is the same and the PCell and SCell simultaneously schedule the SCell or the PCell, the PDCCH candidate monitoring capability allocation scheme and the corresponding overbooking processing are realized, enabling the terminal device to more easily monitor its own PDCCH candidates; and by determining the priority of the search space of the USS, the terminal device can receive the PDCCH in the USS with a higher priority according to the priority, improving the user experience.
[0240] Please refer to Figure 8 , Figure 8 which is a flowchart of another resource scheduling method proposed in the embodiments of the present application. Figure 8 The resource scheduling method shown can be combined with Figure 2 Scheme 1 or Scheme 2 in the scheduling scheme shown and used when the subcarrier spacings of the PCell and SCell are different. As Figure 5 shown, the resource scheduling method includes but is not limited to the following steps.
[0241] 801. The network-side device sends second parameter information to the terminal device;
[0242] 802. The terminal device receives the second parameter information sent by the network-side device; the second parameter information is used to configure the first cell as r 1 cells for PDCCH candidate monitoring capability allocation; the second cell is configured as r 2 cells for PDCCH candidate monitoring capability allocation, and r 1 and r 2 are positive numbers and can be the same or different. The network-side device can determine r 1 and r 2 according to the load conditions of the cells to balance the load. Exemplarily, it can take values such as 0.5, 1, etc.
[0243] In one implementation, the second parameter information includes r 1 and r 2 .
[0244] In one implementation, the second parameter information includes r 2 , and r 1 is a preset value of 1, where the preset value can be a value specified by the protocol.
[0245] In one implementation, the second parameter information includes r, and r 1 = r 2 = r, or, r 1 = r 2 = r / 2.
[0246] Before receiving the second configuration parameter sent by the network-side device, the terminal device further performs the following steps:
[0247] In a possible implementation, the terminal device reports capability information to the network-side device, or does not report capability information when the capability parameter is a preset value; correspondingly, the network-side device confirms the capability parameter R according to the report of the terminal device, or confirms the capability parameter R according to the preset value; where R is used to determine r 1 and r 2 and 1 ≤ r 1 + r 2 ≤ R. Optionally, the protocol stipulates that the terminal device reports capability information. If the terminal device does not report, the network-side device defaults R = 1. If the protocol does not stipulate that the terminal device can report R, the network-side device determines R = 1.
[0248] In a possible implementation, the terminal device reports capability information to the network-side device, or does not report capability information when the capability parameter is a preset value; correspondingly, the network-side device confirms the capability parameters R1 and R2 according to the reported capability information of the terminal device, or confirms the capability parameters R1 and R2 according to the preset value; where R1 and R2 are used to determine r 1 and r 2 and, for example, r 1 ≥ R1 and ≤ 1, r 2 ≥ R2 and ≤ 1, or, r 1 ≤ R1, r 2 ≤ R2.
[0249] In a possible implementation, the terminal device reports capability information to the network-side device, or does not report capability information when the capability parameter is a preset value; correspondingly, the network-side device confirms the capability parameter R1 according to the report of the terminal device, or confirms the capability parameter R1 according to the preset value; where R1 is used to determine r 1 and r 2 and, for example, r 1 ≥ R1 and ≤ 1, r 2 ≥ R1 and ≤ 1, or, r 1 ≤ R1, r 2 ≤ R1.
[0250] Exemplarily, when the PCell and SCell schedule the PCell, the terminal device reports R. If R = 1, it indicates that the terminal device has the ability to map the PCell and SCell to 1 cell; if R = 2, it indicates that the terminal device has the ability to map the PCell and SCell to 2 cells. If the terminal device does not report, the network-side device determines that R = 1; or, if the protocol does not stipulate that the terminal device can report R, the network-side device determines that R = 1; R = 1 indicates that the terminal device has the ability to map the PCell and SCell to 1 cell. Assume R = 2, and the protocol stipulates that r 1 is 1, and the network side can configure r 2 to be 0.5; that is, the PCell is allocated PDCCH candidate monitoring capabilities as 1 cell, and the SCell is allocated PDCCH candidate monitoring capabilities as 0.5 cells.
[0251] Optionally, when allocating PDCCH candidate monitoring capabilities, the PDCCH candidate monitoring capabilities of the terminal device can also be preset by the protocol, including but not limited to the following possible implementation methods.
[0252] In a possible implementation, the protocol presets that the terminal device allocates PDCCH candidate monitoring capabilities for the first cell and the second cell as r cells, where r is a positive number, for example, r is 1 or 2.
[0253] In a possible implementation, the protocol presets that the terminal device allocates PDCCH candidate monitoring capabilities for the first cell as r 1 cells; and for the second cell as r 2 cells for PDCCH candidate monitoring capabilities allocation, where r 1 and r 2 are positive numbers, which can be the same or different, for example, r 1 is 1, and r 2 is 1.
[0254] In a possible implementation, when the subcarrier spacings of the downlink active BWPs of the first cell and the second cell are different, the protocol presets that the terminal device allocates PDCCH candidate monitoring capabilities for the first cell as r 1 cells; and for the second cell as r 2 cells for PDCCH candidate monitoring capabilities allocation, where r 1 and r 2 are positive numbers, which can be the same or different, for example, r 1 is 1, and r 2 is 1.
[0255] Optionally, when allocating PDCCH candidate monitoring capabilities, the following rules are also satisfied. The subcarrier spacing of the active bandwidth part BWP of the first cell is μ1 For a cell with a subcarrier spacing of μ 1 for the first cell, the PDCCH candidates available for carrying the DCI of the second cell are used as r 1 to allocate the PDCCH candidate monitoring capability; for the second cell, the subcarrier spacing of the activated bandwidth part BWP is μ 2 for the second cell, the PDCCH candidates available for carrying the DCI of the second cell are used as r 2 to allocate the PDCCH candidate monitoring capability for a cell with a subcarrier spacing of μ 2 ; where μ 1 and μ 2 are equal or not equal.
[0256] Exemplarily, the first cell is an SCell and the second cell is a PCell. Assume that the subcarrier spacing of the activated bandwidth part BWP of the PCell is 30 KHz, and the PDCCH candidates available for carrying the DCI of the PCell in the PCell correspond to r 1 cells with a subcarrier spacing of 30 KHz in the PDCCH candidate monitoring capability allocation; assume that the subcarrier spacing of the activated bandwidth part BWP of the SCell is 15 KHz, and the PDCCH candidates available for carrying the DCI of the PCell in the SCell correspond to r 2 cells with a subcarrier spacing of 15 KHz.
[0257] 803. The network side device sends first configuration information to the terminal device;
[0258] 804. The terminal device receives the first configuration information sent by the network side device.
[0259] For the specific implementation manners of step 803 and step 804, reference may be made to the description of the relevant steps shown in Figure 2 , which will not be elaborated here.
[0260] Figure 8 The resource scheduling method shown in
[0261] is also applicable to the scenario where the PCell and the SCell simultaneously schedule the SCell. In the embodiments of the present application, the terminal device reports capability information to the network side device, the network side device determines the capability parameter R according to the report of the terminal device, and then determines r according to R. The network side device configures the first cell and the second cell as r cells to allocate the PDCCH candidate monitoring capability. By implementing the embodiments of the present application, when the subcarrier spacing is the same and the PCell and the SCell simultaneously schedule the SCell or the PCell, the PDCCH candidate monitoring capability allocation scheme and the corresponding overbooking processing are realized, and the terminal device can more easily monitor its own PDCCH candidates.
[0262] To better understand the embodiments of the present application, the overall process of a resource scheduling method provided by the embodiments of the present application is described below. As Figure 9 shown, the resource scheduling method includes the following steps 901 - step 908.
[0263] 901. The network - side device configures a cell for the terminal device.
[0264] Among them, the cell configuration is used to represent the serving cell configured to provide services for the terminal device. Optionally, the terminal device may be configured in different working scenarios. Exemplarily, two sets of cell groups are configured. The first set of cell groups is serving cells, on which no CORESET Pool Index is configured, or a CORESET Pool Index is configured, but the same value is configured on all CORESETs of all downlink BWPs of each cell. Then the first set of cell groups does not support multi - TRP serving cells. The second set of cell groups is serving cells, on any downlink BWP of these serving cells, the CORESET Pool Index of a first CORESET is configured as 0, and the CORESET Pool Index of a second CORESET is configured as 1. Then the second set of cell groups can support multi - TRP serving cells.
[0265] 902. The terminal device reports monitoring capability information to the network - side device. Correspondingly, the network - side device receives the monitoring capability information reported by the terminal device.
[0266] 903. The network - side device determines the PDCCH candidate monitoring capability of the terminal device according to the monitoring capability information reported by the terminal device.
[0267] The PDCCH candidate monitoring capability of the terminal device is described below according to different working scenarios of the terminal device.
[0268] 1) R15 non - NR - DC related working scenarios and the PDCCH candidate monitoring capability of the terminal device
[0269] Among them, the R15 related working scenarios include: R15 non - multi - TRP single - cell / CA, R15 multi - TRP single - cell / CA, and R15 non - multi - TRP single - cell / CA plus R15 multi - TRP single - cell / CA.
[0270] When then the terminal device is configured in the R15 non - multi - TRP single - cell / CA working scenario;
[0271] When happens, the terminal device is configured for the single-cell / CA working scenario of R15 multi-TRP;
[0272] When happens, the terminal device is configured for the single-cell / CA working scenario of non-multi-TRP in R15 plus the single-cell / CA working scenario of multi-TRP.
[0273] The terminal device may report a PDCCH candidate monitoring capability (pdcch-BlindDetectionCA) converted to the number of cells, and / or report a monitoring capability parameter R. The value of R can determine that the number of serving cells is When the terminal device does not report, R = 1.
[0274] When the terminal device can allocate the processing capabilities of the PDCCHs of two TRPs as if they were the PDCCHs of two cells, the terminal device may report R = 2. When the terminal device can only process the PDCCHs of two TRPs as if they were the PDCCH of one cell, the terminal device reports R = 1.
[0275] If a terminal device reports in UE-NR-Capability that it can support carrier aggregation of more than 4 serving cells, and no downlink cell is configured with a PDCCH monitoring capability configuration (Monitoring Capability Config), or all downlink cells where the terminal device detects the PDCCH are configured with a PDCCH Monitoring Capability Config as the R15 PDCCH monitoring capability, then the terminal device shall give an indication information in UE-NR-Capability, indicating the maximum number of PDCCH candidates that can be detected per slot and the maximum number of non-overlapping CCEs when the terminal device is configured with carrier aggregation of more than 4 cells.
[0276] In the non-NR-DC mode, the terminal device determines the maximum number of PDCCH candidates that can be detected per slot and the maximum number of non-overlapping CCEs as downlink cells.
[0277] Among them, if the terminal device does not report pdcch-BlindDetectionCA, then is is the number of configured downlink cells. Otherwise, is the pdcch-BlindDetectionCA reported by the terminal device.
[0278] For carrier aggregation with more than 4 cells, the terminal device does not expect the number of PDCCH candidates detected in each slot and the number of non-overlapping CCEs to be greater than the corresponding values.
[0279] 2) R15 NR-DC working scenarios and the PDCCH candidate monitoring capabilities of the terminal device
[0280] In the NR-DC mode, the terminal device determines the maximum number of PDCCH candidates that can be detected in each slot and the maximum number of non-overlapping CCEs:
[0281] For MCG, it is where is the pdcch-BlindDetection of MCG reported by the terminal device;
[0282] For SCG, it is where is the pdcch-BlindDetection of SCG reported by the terminal device;
[0283] For a cell group CG under NR-DC, the terminal device does not expect the number of PDCCH candidates detected in each slot and the number of non-overlapping CCEs to be greater than the corresponding values.
[0284] 3) R16-related working scenarios and the PDCCH candidate monitoring capabilities of the terminal device
[0285] R16-related working scenarios include: R16 single-cell / CA without multi-TRP.
[0286] If the terminal device indicates a carrier aggregation capability of more than X downlink cells in UE-NR-Capability-r16, then when the terminal device is configured for carrier aggregation with more than X downlink cells, the terminal device indicates in UE-NR-Capability-r16 the maximum number of PDCCH candidates that can be detected in each span and the maximum number of non-overlapping CCEs.
[0287] In the non-NR-DC mode, and if all downlink cells for detecting PDCCH are configured with PDCCH MonitoringCapability Config as R16 PDCCH monitoring capability, then the terminal device determines that the maximum number of PDCCH candidates that can be detected in each span and the maximum number of non-overlapping CCEs correspond to downlink cells.
[0288] If the terminal device does not report pdcch - BlindDetectionCA - r16, then is the number of configured downlink cells;
[0289] Otherwise, is the pdcch - BlindDetectionCA - r16 reported by the terminal device.
[0290] 4) R15 and R16 related working scenarios and the PDCCH candidate monitoring capabilities of the terminal device
[0291] The R15 and R16 related working scenarios include: R15 and R16 non - multi - TRP CA.
[0292] If the terminal device indicates in UE - NR - Capability - r15 or UE - NR - Capability - r16 a CA capability for more than Y downlink cells or more than Z downlink cells, then when the terminal device is configured for CA with more than Y or Z downlink cells, and at least one from the Y downlink cells and at least one from the Z downlink cells, the terminal device uses PDCCH Monitoring CapabilityConfig for R15 PDCCH monitoring capability or PDCCH Monitoring Capability Config for R16 PDCCH monitoring capability in UE - NR - Capability - r15 or UE - NR - Capability - r16 to indicate the maximum number of PDCCH candidates and the maximum number of non - overlapping CCEs.
[0293] In non - DC mode, the terminal device determines the ability for downlink cells or downlink cells to detect the maximum number of PDCCH candidates and the maximum number of non - overlapping CCEs per slot or per span as:
[0294] If the terminal device does not report pdcch - BlindDetectionCA - r15, then is the number of configured downlink cells;
[0295] Otherwise, is the pdcch - BlindDetectionCA - r15 reported by the terminal device.
[0296] If the terminal device does not report pdcch - BlindDetectionCA - r16, then is the number of configured downlink cells;
[0297] Otherwise, It is pdcch-BlindDetectionCA-r16 reported by the terminal device.
[0298] 904. If the number of cells configured by the network side device for the terminal device is less than or equal to the PDCCH candidate monitoring capability of the terminal device, then determine that the upper limit of the PDCCH candidate monitoring capability of the terminal device in each cell is the value specified by the protocol shown in Tables 2-1 to 2-4. Then perform step 906.
[0299] If the terminal device does not report pdcch-BlindDetectionCA, or the blind detection factor R (BDFactorR) is not configured, then γ = R;
[0300] If the terminal device reports pdcch-BlindDetectionCA, then the terminal device can be configured with BDFactorR, and the value is γ = 1 or γ = R. Among them, pdcch-BlindDetectionCA can be the pdcch-BlindDetectionCA, pdcch-BlindDetectionCA-r15 or pdcch-BlindDetectionCA-r16 in step 203.
[0301] When the number of configured cells is less than or equal to the terminal device capability (when γ = 1, a cell containing 2 TRPs is considered as 1 cell, when γ = 2, a cell containing 2 TRPs is considered as 2 cells):
[0302] On each non-multi-TRP cell and each TRP, the number of PDCCH candidates and non-overlapping CCEs that the terminal device needs to monitor is less than or equal to the upper limit of the PDCCH candidate monitoring capability of a single terminal device;
[0303] On each multi-TRP cell, the number of PDCCH candidates and non-overlapping CCEs that the terminal device needs to monitor is less than or equal to γ times the upper limit of the PDCCH candidate monitoring capability of a single terminal device.
[0304] 905. If the number of cells configured by the network side device for the terminal device is greater than the PDCCH candidate monitoring capability of the terminal device, then perform PDCCH candidate monitoring capability allocation. Then perform step 906.
[0305] PDCCH candidate monitoring capability allocation includes but is not limited to determining the upper limit of the PDCCH candidate monitoring capability of the terminal device in each cell of each subcarrier spacing, determining the upper limit of the PDCCH candidate monitoring capability of the terminal device in each cell, and determining the upper limit of the PDCCH candidate monitoring capability of the terminal device in each TRP.
[0306] When the number of configured cells is greater than the terminal device's capabilities, the network-side device groups the cells. For example, a group with the same subcarrier spacing. According to the proportion of the number of cells in this group (each multi-TRP can be regarded as γ cells) in the total number of cells, the corresponding capabilities are allocated from the total PDCCH candidate monitoring capabilities of the terminal device to obtain the upper limit of the total number of PDCCH candidates and non-overlapping CCEs corresponding to this subcarrier spacing.
[0307] For a certain subcarrier spacing, for all cells with the same subcarrier spacing, the number of PDCCH candidates and non-overlapping CCEs that the terminal device needs to monitor is less than or equal to the upper limit of the total number.
[0308] For each non-multi-TRP cell, the number of PDCCH candidates and non-overlapping CCEs that the terminal device needs to monitor is less than or equal to the minimum value between the upper limit of the PDCCH candidate monitoring capabilities of a single terminal device and the upper limit of the total number corresponding to the subcarrier spacing.
[0309] For each multi-TRP cell, the number of PDCCH candidates and non-overlapping CCEs that the terminal device needs to monitor is less than or equal to the minimum value between γ times the upper limit of the PDCCH candidate monitoring capabilities of a single terminal device and the upper limit of the total number corresponding to the subcarrier spacing.
[0310] For a certain TRP in each multi-TRP cell, the number of PDCCH candidates and non-overlapping CCEs that the terminal device needs to monitor is less than or equal to the minimum value between the upper limit of the PDCCH candidate monitoring capabilities of a single terminal device and the upper limit of the total number corresponding to the subcarrier spacing.
[0311] Optionally, the following method can be used to allocate the PDCCH candidate monitoring capabilities of the terminal device:
[0312] In one implementation, if the terminal device configures activated BWPs of downlink cells with an SCS of μ, and then on the activated downlink BWP of this scheduled cell. Among them, can be the in step 903
[0313] When the scheduled cell belongs to downlink cells among cells, for each slot of each scheduled cell, the terminal device does not need to detect more than PDCCH candidates, nor does it need to detect more than
[0314] When the scheduled cell belongs to When it is a downlink cell in a cell, for each slot of each scheduled cell, the terminal device does not need to detect more than PDCCH candidates, nor does it need to detect more than non-overlapping CCEs.
[0315] When the scheduled cell belongs to downlink cells in a cell, for each slot of each scheduled cell, on the CORESET with the same CORESETPoolIndex value, the terminal device does not need to detect more than PDCCH candidates, nor does it need to detect more than non-overlapping CCEs.
[0316] In one implementation, if the terminal device is configured with downlink cells with an SCS configured as μ, and The downlink BWP of an active cell is the active BWP of this active cell, and the downlink BWP of a non-active cell is the BWP with the serial number firstActiveDownlinkBWP-Id of this non-active cell. In For each slot of the active downlink BWP of the scheduled cell of the downlink cell, the terminal device does not need to detect more than PDCCH candidates, nor does it need to detect more than non-overlapping CCEs.
[0317] For each scheduled cell, if the scheduled cell belongs to downlink cells in a cell, on each slot of the active BWP with a subcarrier configuration of μ, the terminal device does not need to detect more than PDCCH candidates, nor does it need to detect more than non-overlapping CCEs.
[0318] For each scheduled cell, if the scheduled cell belongs to downlink cells in a cell, on each slot of the active BWP with a subcarrier configuration of μ, the terminal device does not need to detect more than PDCCH candidates, nor does it need to detect more than non-overlapping CCEs.
[0319] On the CORESET with the same CORESET Pool Index value, the terminal device does not need to detect more than PDCCH candidates, nor does it need to detect more than non-overlapping CCEs.
[0320] The CSS set configured by the terminal device is not expected, resulting in the total number of detected PDCCH candidates or non-overlapping CCEs, or the value for each scheduled cell, being greater than the corresponding maximum value on any slot.
[0321] For intra-cell scheduling or inter-cell scheduling, if the SCS configurations of the downlink BWP of the scheduling cell and the scheduled cell are both μ, the number of monitored PDCCH candidates or non-overlapping CCEs configured for the SCell by the terminal device is not expected to be greater than the corresponding maximum value.
[0322] 906. The network device configures the resource location of the PDCCH candidate for the terminal device in the cell according to the PDCCH candidate monitoring capability of the terminal device. The number of PDCCH candidates configured for some cells is less than or equal to the upper limit of the PDCCH candidate monitoring capability of the terminal device; the number of PDCCH candidates configured for some cells is allowed to be higher than the upper limit of the PDCCH candidate monitoring capability of the terminal device, that is, Overbooking will occur.
[0323] 907. If Overbooking occurs, the terminal device needs to perform Overbooking processing in the cell where Overbooking occurs.
[0324] The specific implementation manners of step 906 and step 907 can refer to Figure 2 - Figure 8 the relevant descriptions in the resource scheduling method shown, which will not be elaborated here.
[0325] 908. The network device sends the PDCCH in the configured PDCCH candidate.
