It should also be understood that in the embodiments of the present application, the "protocol" may refer to a standard protocol in the field of communications, such as LTE protocols, NR protocols, and related protocols used in future communication systems, and the present application does not limit this.

[0049] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0050] (1) Determination of PDCCH detection capability

[0051] In order to ensure that the number of PDCCH detections configured by the network is within the capabilities of the terminal, the NR protocol stipulates the PDCCH detection capability.

[0052] When the blind detection or blind channel estimation required for the PDCCH to be detected configured by the network exceeds the PDCCH detection capability of the terminal, the terminal stops detecting PDCCH on the remaining PDCCH candidate resources. For multi-carrier systems, the protocol requires that the PDCCH candidate resources configured by the network on the secondary cell (SCell) will not exceed the PDCCH detection capability of the terminal. The PDCCH candidate resources configured on the Pcell can exceed the PDCCH detection capability of the terminal, but in the case of exceeding the PDCCH detection capability, the terminal stops detecting PDCCH on the remaining PDCCH candidate resources.

[0053] For single-carrier systems, the blind detection capability is achieved by and Let's make an agreement. and The specific values ​​of are shown in Table 1 and Table 2. Or as shown in Table 2 Can be pre-configured in the terminal. Refers to the maximum number of blind detections of a terminal on a carrier. The number of blind detections is related to the number of DCI sizes to be detected, the aggregation level, and the size of the candidate position set within each aggregation level. The candidate position set includes multiple PDCCH candidate resources, namely, PDCCH candidates, and the number of PDCCH candidates included in the candidate position set is the candidate position set size. For example, if a terminal is configured with 2 DCI formats, the number of DCI sizes to be detected is also 2, and there are 2 aggregation levels. The candidate position set size corresponding to aggregation level 1 is 4, and the candidate position set size corresponding to aggregation level 2 is 8. The number of blind detections required by the terminal is (4+8)*2=24. Refers to the maximum number of non-overlapping control channel elements (CCE) for blind channel estimation of a terminal on one carrier.

[0054] For multi-carrier systems, since the PDCCH detection capability cannot increase linearly with the increase in the number of carriers, the total capability of PDCCH detection in multi-carrier situations is constrained by constraining the maximum number of carriers for PDCCH detection:

[0055] When the number of carriers configured for the terminal is less than or equal to the maximum number of carriers of the multi-carrier PDCCH blind detection capability reported by the terminal, the maximum number of PDCCH candidates and the number of non-overlapping CCEs detected by the terminal are the same as those of the single-carrier system.

[0056] When the number of carriers configured for the terminal is greater than or equal to the maximum number of carriers of the multi-carrier PDCCH blind detection capability reported by the terminal (the maximum number of carriers is only used to calculate the total capability of PDCCH detection and does not limit the number of scheduled carriers), the maximum number of PDCCH candidates and the maximum number of non-overlapping CCEs detected by the terminal are determined by the following method:

[0057] For each scheduled carrier, the number of PDCCH blind detections shall not exceed The number of non-overlapping CCEs shall not exceed in, and For specific values ​​of , see Table 1 and Table 2. and is determined as follows:

[0058]

[0059] in, The maximum number of carriers detected by the PDCCH reported by the terminal. is the number of scheduled carriers corresponding to the carrier with parameter set (numerology) j, where Numerology includes μ, subcarrier spacing, cyclic prefix, TTI length and system bandwidth. The value range of j is μ: 0 to 3, μ indicates the subcarrier spacing of the activated bandwidth part (Bandwidth Part, BWP) of the scheduled carrier, that is, the terminal is not required to detect more than 10000 cells on all scheduled cells with subcarrier spacing corresponding to μ. The number of PDCCH candidates is greater than The number of non-overlapping CCEs, that is, and What is affected are: the subcarrier spacing of the scheduling cell, the number of scheduled cells corresponding to the scheduling cell or the scheduling cell group with the same subcarrier spacing.

[0060] Table 1 Corresponding relationship with μ

[0061]

[0062] Table 2 Corresponding relationship with μ

[0063]

[0064] The detection capability of PDCCH has been adjusted accordingly considering the enhancement of PDCCH detection capability based on time span, PDCCH detection enhancement in multiple transmission point (Transmit / Receive Point, TRP) scenarios, and application of dual connectivity (Dual Connectivity, DC) scenarios, which will not be explained in detail here.

[0065] (2) Cross-carrier scheduling configuration

[0066] The cross-carrier scheduling configuration (IE CrossCarrierSchedulingConfig) is used to configure the information of the scheduling cell corresponding to the scheduled cell, as well as the value of the carrier indicator field (CIF) corresponding to the scheduled cell in the scheduling cell. The CIF corresponding to the scheduled cell is the indication field in the DCI used to indicate the scheduled carrier. The cross-carrier configuration mainly refers to IE CrossCarrierSchedulingConfig, and other cross-carrier related configuration information is not excluded.

[0067] Optionally, IE CrossCarrierSchedulingConfig may include the following two selected fields: CIF existence field cif-Presence and scheduled cell field scheduled cell, wherein cif-Presence is used to indicate whether the current scheduled cell is self-scheduled, and scheduled cell is used to indicate the scheduling cell corresponding to the scheduled cell, wherein scheduled cell includes: schedulingCellId indicating the scheduling cell, and field cif-InSchedulingCell indicating the value of the CIF corresponding to the scheduled cell in the scheduling cell.

[0068] It can be seen from the CrossCarrierSchedulingConfig configuration that during the standardization process, a scheduled cell can be scheduled by at most one scheduling cell, and gradually it can additionally support the primary cell (PCell) to be scheduled by two scheduling cells, PCell and Scell, but the corresponding terminal capability reporting is required to support it, and the specific implementation method will not be repeated here.

[0069] In the related technology, a DCI-scheduled resource is limited to one carrier. When R18 introduces a scheme for one DCI to schedule the PDSCH / PUSCH of multiple scheduled cells, it will appear that one DCI-scheduled resource corresponds to multiple scheduled cells, or in other words, multiple scheduled cells correspond to one DCI. For this situation of "multiple scheduled cells corresponding to one DCI", whether there needs to be restrictions on multiple scheduled cells scheduled by one DCI, and whether it affects the division of PDCCH detection capabilities, are basic issues that need to be discussed. The design of restrictions / schemes will also affect the complexity of implementing the feature of "one DCI scheduling multiple scheduled cells".

[0070] It should be noted that in the embodiments of the present application, detection can be understood as monitoring, and detection and monitoring can be interchangeable.

[0071] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0072] The wireless communication method provided in the embodiment of the present application is applied to a terminal device, such as Figure 2 As shown, including:

[0073] S201. A terminal device receives a first DCI sent by a network device, where the first DCI is used to schedule channels of at least two first cells.

[0074] The wireless communication method provided in the embodiment of the present application is applied to a terminal device, such as Figure 3 As shown, including:

[0075] S301. A network device sends a first DCI to a terminal device, where the first DCI is used to schedule channels of at least two first cells.

[0076] The embodiment of the present application also provides a wireless communication method applied to a wireless communication system, wherein the wireless communication system includes a terminal device and a network device, wherein the description of the terminal device is as follows Figure 2 For a description of the wireless communication method shown, see the description of the network device. Figure 3 The description of the wireless communication method shown in the figure is omitted here for the wireless communication method applied to the wireless communication system.

[0077] In the embodiment of the present application, the network device sends the first DCI on the PDCCH, and the channels scheduled by the first DCI include: PDSCH and / or PUSCH. The channels scheduled by the first DCI correspond to at least two first cells.

[0078] In one example, the channels scheduled by the first DCI include PDSCH1, PDSCH2, PUSCH1, and PUSCH2, wherein PDSCH1 corresponds to cell 1, PDSCH2 and PUSCH2 correspond to cell 2, and PUSCH3 corresponds to cell 3. At this time, at least two first cells corresponding to the channels scheduled by the first DCI include: cell 1, cell 2, and cell 3.

[0079] In the embodiment of the present application, the cell carrying the first DCI is a scheduling cell corresponding to at least two first cells, and each of the at least two first cells is a scheduled cell scheduled by the scheduling cell.

[0080] In the embodiment of the present application, a plurality of scheduled cells that can be simultaneously scheduled by a scheduling cell may constitute a scheduled cell group.

[0081] In one example, at least two first cells corresponding to the channel scheduled by the first DCI include: cell 1, cell 2 and cell 3. The first DCI is carried on cell 1, and cell 1 schedules cell 1, cell 2 and cell 3 at the same time, that is, cell 1 schedules cell 1+cell 2+cell 3. At this time, cell 1 is the scheduling cell that schedules cell 1, cell 2 and cell 3 at the same time, and cell 1+cell 2+cell 3 constitutes a scheduled cell group.

[0082] In the embodiment of the present application, one scheduling cell may schedule one or more scheduled cell groups.

[0083] In an embodiment of the present application, different cells correspond to different carriers, and cells and carriers can be replaced. Therefore, the first DCI used to schedule channels of at least two first cells can be understood as the first DCI used to schedule channels of at least two first carriers, and the scheduled cell group can be understood as the scheduled carrier group.

[0084] The wireless communication method provided in the embodiment of the present application can be applied to a carrier aggregation (CA) scenario. The CA system supports self scheduling and cross-carrier scheduling. CA can include multiple carriers.

[0085] In the solution provided in this embodiment, DCI is sent in the scheduling cell, i.e., the scheduling carrier, and the channel scheduled by DCI is the channel of the scheduled cell, i.e., the scheduled carrier. The downlink signal and uplink signal in each carrier are respectively limited to the activated downlink bandwidth part (DL BWP) and the activated downlink bandwidth part (UL BWP).

[0086] In the embodiment of the present application, the relationship between the scheduled cell group and the scheduling cell can be called the second scheduling relationship, that is, the relationship between the cells configured with the terminal device and one scheduling cell corresponding to multiple scheduled cells at the same time is the second scheduling relationship.

[0087] In one example, the second scheduling relationship may be as follows: Figure 4 As shown, the cells configured with the terminal device include: cell 1, cell 2, cell 3 and cell 4. The scheduled cell group corresponding to cell 1 is: cell 1 + cell 3, the scheduled cell group corresponding to cell 2 is: cell 2 + cell 3, and the scheduled cell group corresponding to cell 4 is: cell 3 + cell 4. In the case where at least two first cells include cell 1 and cell 3, the cell carrying the first DCI is cell 1.

[0088] In an embodiment of the present application, a first scheduling relationship may also exist between the cells configured with the terminal device, wherein in the first scheduling relationship, one scheduling cell corresponds to one scheduled cell.

[0089] In one example, the cells configured for the terminal device include: cell 1, cell 2, cell 3 and cell 4, and the first scheduling relationship may be as follows: Figure 5 As shown, the scheduled cells corresponding to cell 1 include: cell 1 and cell 2, and the scheduled cells corresponding to cell 3 include cell 3 and cell 4. At this time, cell 1 can schedule cell 1 alone, and can also schedule cell 2 alone, and cell 3 can schedule cell 3 alone, and can also schedule cell 4 alone.

[0090] In the embodiment of the present application, the scheduling relationship between the cells configured by the terminal device, that is, the third scheduling relationship, may include the first scheduling relationship and the second scheduling relationship. In an example, the cells configured by the terminal device include: cell 1, cell 2, cell 3 and cell 4, and the third scheduling relationship may be as follows: Figure 6 Shown, including Figure 5 The first scheduling relationship shown and Figure 4 In the second scheduling relationship shown, the scheduled cells corresponding to cell 1 include: cell 1 + cell 3, cell 1, cell 3; the scheduled cells corresponding to cell 2 include: cell 2 + cell 3; the scheduled cells corresponding to cell 3 include: cell 3 and cell 4; the scheduled cells corresponding to cell 4 include: cell 3 + cell 4.

[0091] In some embodiments, in the first scheduling relationship, each of the at least two first cells corresponds to the same scheduling cell, that is, all of the at least two first cells correspond to the same scheduling cell.

[0092] Here, at least two first cells belong to a scheduled cell group. When the scheduling cells corresponding to at least two first cells scheduled by the first DCI are the same, the terminal device supports capability A: the scheduling cells corresponding to each scheduled cell in the scheduled cell group are the same scheduling cell.

[0093] In one example, at least two first cells include: cell A and cell B, and the scheduling cell corresponding to cell A+cell B is cell C. Then, in the first scheduling relationship, the scheduling cells corresponding to cell A and cell B are the same, which is cell C, that is, the scheduling cell corresponding to cell A is cell C, and the scheduling cell corresponding to cell B is cell C.

[0094] In some embodiments, the terminal device does not expect that the scheduling cell corresponding to each of the at least two first cells is not the same scheduling cell.

[0095] The scheduling cells corresponding to the first cells are not the same scheduling cell, and at least two first cells constitute a scheduled cell group. Then the terminal device does not expect that the scheduling cells corresponding to the scheduled cells in the scheduled cell group are not the same scheduling cell. At this time, the terminal device supports capability A: the scheduling cells corresponding to the scheduled cells in the scheduled cell group are the same scheduling cell.

[0096] In the embodiment of the present application, when the terminal device supports capability A, when the network device sends DCI to the terminal device, among at least two scheduled cells corresponding to the channel scheduled by the sent DCI, different scheduled cells correspond to the same scheduling cells. When among at least two scheduled cells corresponding to the channel scheduled by the DCI sent by the network device, different scheduled cells correspond to different scheduling cells, the terminal device considers that an error case has occurred and can decide the handling method according to the setting.

[0097] In one example, the cells configured with the terminal device include: cell 1, cell 2, cell 3, cell 4, cell 5 and cell 6, the scheduled cells corresponding to cell 1 include: cell 1 and cell 2, the scheduled cells corresponding to cell 3 include: cell 3 and cell 4, the scheduled cells corresponding to cell 5 include cell 5 and cell 6, then the scheduled cell group may include: cell 1 + cell 2, cell 3 + cell 4, cell 5 + cell 6, and the terminal device does not expect the following cell combinations of cell 1 + cell 3, cell 2 + cell 3, cell 1 + cell 5, cell 3 + cell 6 to be the scheduled cells: {cell 1, cell 2}, {cell 3, cell 4}, {cell 5, cell 6}, for example.

[0098] In the embodiment of the present application, if the scheduling cells corresponding to each scheduled cell in the scheduled cell group are the same, then the scheduled cell group may be a subset of the cell group consisting of multiple scheduled cells corresponding to the scheduling cell.

[0099] In one example, the cells configured with the terminal device include: cell 1, cell 2, cell 3 and cell 4. In the first scheduling relationship, the scheduled cells corresponding to cell 1 include: cell 1, cell 2 or cell 3, and the scheduled cell corresponding to cell 4 is cell 4. Then, the scheduled cell group corresponding to cell 1 may be a combination of multiple scheduled cells in cell 1, cell 2 and cell 3, such as: cell 1+cell 2, cell 2+cell 3, cell 1+cell 2+cell 3.

[0100] In an embodiment of the present application, when one DCI can schedule channels of multiple scheduled cells, that is, when one scheduling cell schedules a scheduled cell group, the scheduling cells corresponding to each scheduled cell in the scheduled cell group are the same. At this time, one scheduled cell corresponds to one scheduling cell, which can avoid the situation where one scheduled cell is scheduled by multiple scheduling cells, thereby reducing the complexity of scheduling implementation.

[0101] In some embodiments, the terminal device does not report the first capability indication information to the network device.

[0102] At this time, the network device has not received the first capability indication information reported by the terminal device.

[0103] When the terminal device fails to report the first capability indication information to the network device, and the network device fails to receive the first capability indication information reported by the terminal device, it is determined that the terminal device does not expect that the scheduling cell corresponding to each scheduled cell in the scheduled cell group is not the same scheduling cell. It can also be understood that at this time, the terminal device only supports that the scheduling cell corresponding to each scheduled cell in the scheduled cell group is the same scheduling cell, and when the network device sends a DCI scheduling channel of the scheduled cell group to the terminal device, the scheduling cells corresponding to each scheduled cell in the scheduled cell group in the first scheduling relationship are the same.

[0104] In some embodiments, in the first scheduling relationship, the scheduling cell of each of the at least two first cells is the same or not the same scheduling cell.

[0105] Here, at least two first cells belong to a scheduled cell group. When the scheduling cells corresponding to at least two first cells scheduled by the first DCI are not the same scheduling cell, the terminal device supports capability B: in the scheduled cell group, the scheduling cells corresponding to each scheduled cell are not the same scheduling cell.

[0106] In the embodiment of the present application, capability A is the basic capability of the terminal device, and capability B is a higher-level capability than capability A. When the terminal device supports capability B, it can also support capability A.

[0107] When the terminal device supports capability B, the scheduling cells corresponding to the scheduled cells in the scheduled cell group may be the same scheduling cell or may not be the same scheduling cell.

[0108] In one example, the cells configured with the terminal device include: cell 1, cell 2, cell 3 and cell 4, the scheduled cells corresponding to cell 1 include: cell 1, cell 2 or cell 3, the scheduled cell corresponding to cell 4 is cell 4, and when the terminal device supports capability B, the scheduled cell group corresponding to cell 1 includes a combination of multiple scheduled cells in cell 1, cell 2, cell 3 and cell 4, such as: cell 1 + cell 4, cell 2 + cell 3 + cell 4, cell 1 + cell 2 + cell 3 + cell 4, and the scheduled cell group corresponding to cell 1 may also include a combination of multiple scheduled cells in cell 1, cell 2 and cell 3, such as: cell 1 + cell 2, cell 2 + cell 3, cell 1 + cell 2 + cell 3.

[0109] In an embodiment of the present application, when one DCI can schedule channels of multiple scheduled cells, that is, when one scheduling cell schedules a scheduled cell group, the scheduling cells corresponding to each scheduled cell in the scheduled cell group are not the same scheduling cell, and the restriction that the scheduling cells corresponding to different scheduled cells in the scheduled cell group are the same can be lifted. At this time, the configuration or scheduling flexibility of the carrier or cell can be improved.

[0110] In some embodiments, the terminal device reports first capability indication information to the network device.

[0111] At this time, the network device receives the first capability indication information sent by the terminal device.

[0112] When the terminal device supports capability B, it may report first capability indication information to the network device. When the network device receives the first capability indication information reported by the terminal device, it determines that the terminal device supports that the scheduling cells corresponding to each scheduled cell in the scheduled cell group are not the same scheduling cells. When the DCI sent by the network device to the terminal device schedules the channel of the scheduled cell group, the scheduling cells corresponding to each scheduled cell in the scheduled cell group may be the same scheduling cell or may not be the same scheduling cell.

[0113] In an embodiment of the present application, the first capability indication information is used to indicate that the terminal device supports at least one of the following:

[0114] One DCI schedules channels of at least two scheduled cells, and the scheduling cells corresponding to each of the at least two scheduled cells are not the same scheduling cell;

[0115] A scheduled cell is scheduled by at least two scheduling cells.

[0116] When the terminal device supports a DCI scheduling channel of at least two scheduled cells, and the scheduling cells corresponding to each of the at least two scheduled cells are not the same scheduling cell, the terminal device is considered to support the first capability, and the first capability is the capability that a DCI schedules a channel of at least two scheduled cells, and the scheduling cells corresponding to each of the at least two scheduled cells are not the same scheduling cell.

[0117] When the terminal device supports one scheduled cell being scheduled by at least two scheduling cells, it is considered that the terminal device supports the second capability, and the second capability is the capability of one scheduled cell being scheduled by at least two scheduling cells. At this time, one scheduled cell may correspond to at least two scheduling cells.

[0118] In the embodiment of the present application, the capability indicated by the first capability indication information may also include a variation of the second capability, such as: the scheduled cell supports not only self-scheduling but also cross-carrier scheduling. In the embodiment of the present application, there is no limitation on the variation of a scheduled cell being scheduled by at least two scheduling cells.

[0119] In an embodiment of the present application, on the basis of the first scheduling relationship, a scheduling relationship between the scheduled cell group and the scheduling cell is added. When the scheduling cells corresponding to the scheduled cells in a scheduled cell group are not the same scheduling cell, there must be some scheduled cells in the scheduled cell group that can be scheduled by more than one scheduling cell. For the same scheduled cell, the number of optional cells for the base station to send PDCCH increases, the PDCCH scheduling flexibility is high, and the probability of PDCCH blocking (blockage) is low.

[0120] In some embodiments, in the first scheduling relationship, the first parameter corresponding to the scheduling cell of each of the at least two first cells is the same, and the first parameter is the subcarrier spacing (Sub-Carrier Space, SCS), or the first parameter is used to define the subcarrier spacing and / or cyclic prefix (Cyclic Prefix, CP).

[0121] Here, at least two first cells belong to a scheduled cell group. When the first parameter corresponding to the scheduling cell corresponding to at least two first cells scheduled by the first DCI is the same first parameter, the terminal device supports capability C: in the scheduled cell group, the first parameter corresponding to the scheduling cell corresponding to each scheduled cell is the same first parameter.

[0122] Optionally, when the first parameter is used to define the SCS and / or cyclic prefix, the first parameter is Numerology.

[0123] In one example, at least two first cells include: cell A and cell B, and the scheduling cell corresponding to cell A+cell B is cell C. Then, in the first scheduling relationship, the first parameter corresponding to the scheduling cells corresponding to cell A and cell B is the same, which is the first parameter A, and the SCS indicated by the first parameter A is 15kHz, that is, the SCS corresponding to the scheduling cell corresponding to cell A is 15kHz, and the SCS corresponding to the scheduling cell corresponding to cell B is 15kHz.

[0124] In some embodiments, the terminal device does not expect that the first parameter corresponding to the scheduling cell corresponding to each of the at least two first cells is not the same first parameter.

[0125] The first parameter corresponding to the scheduling cell corresponding to each first cell is not the same first parameter, and at least two first cells constitute a scheduled cell group. The terminal device does not expect that the first parameter corresponding to the scheduling cell corresponding to each scheduled cell in the scheduled cell group is not the same first parameter. At this time, the terminal device supports that the first parameter corresponding to the scheduling cell corresponding to each scheduled cell in the scheduled cell group is the same first parameter.

[0126] In the embodiment of the present application, when the terminal device supports capability C, when the network device sends DCI to the terminal device, the first parameter corresponding to the scheduling cell corresponding to different scheduled cells in at least two scheduled cells corresponding to the channel scheduled by the sent DCI is the same first parameter. When the first parameter corresponding to the scheduling cell corresponding to different scheduled cells in at least two scheduled cells corresponding to the channel scheduled by the DCI sent by the network device is not the same first parameter, the terminal device believes that an error case has occurred and can decide the processing method according to the setting.

[0127] In one example, the cells configured with the terminal device include: cell 1, cell 2, cell 3, cell 4, cell 5 and cell 6, the SCS corresponding to cell 1 and cell 3 is 15kHz, the SCS corresponding to cell 2, cell 4 and cell 6 is 60kHz, the SCS corresponding to cell 5 is 30kHz, the scheduled cells corresponding to cell 1 include: cell 1 and cell 2, the scheduled cells corresponding to cell 3 include: cell 3 and cell 4, the scheduled cells corresponding to cell 5 include cell 5 and cell 6, then the scheduled cells included in the scheduled cell group supported by the terminal device are the following combinations of scheduled cells corresponding to the scheduling cells of 15kHz: cell 1, cell 2, cell 3 and cell 4, and the terminal device does not support the combination of cells in {cell 1, cell 2, cell 3 and cell 4} and cells in {cell 4, cell 5}, for example: the terminal device does not support: cell 1+cell 5, cell 2+cell 5, cell 1+cell 6, cell 3+cell 6, etc.

[0128] Optionally, the scheduling cells corresponding to the same first parameter include one scheduling cell or multiple scheduling cells. When the same first parameter corresponds to multiple scheduling cells, the scheduling cell corresponding to the scheduled cell group may be any scheduling cell among the multiple scheduling cells.

[0129] In an embodiment of the present application, when one DCI can schedule channels of multiple scheduled cells, that is, when one scheduling cell corresponds to a scheduled cell group, the first parameter corresponding to the scheduling cell corresponding to each scheduled cell in the scheduled cell group is the same. At this time, the calculation of the PDCCH detection capability of the terminal device on all scheduling cells corresponding to the subcarrier spacing μ is the same as "a channel of a scheduled cell scheduled by one DCI", and is not affected by "a channel of multiple scheduled cells scheduled by one DCI". Therefore, the division of PDCCH detection capability maximizes the reuse of existing mechanisms and has good backward compatibility.

[0130] In some embodiments, the terminal device does not report the second capability indication information to the network device.

[0131] At this time, the network device does not receive the second capability indication information reported by the terminal device.

[0132] When the terminal device does not report the second capability indication information to the network device, and the network device does not receive the second capability indication information reported by the terminal device, it is determined that the terminal device does not expect that the first parameter corresponding to the scheduling cell corresponding to each scheduled cell in the scheduled cell group is the same first parameter. It can also be understood that at this time, the terminal device only supports the first parameter corresponding to the scheduling cell corresponding to each scheduled cell in the scheduled cell group to be the same first parameter. When the network device sends a DCI scheduling channel of the scheduled cell group to the terminal device, the first parameter corresponding to the scheduling cell corresponding to each scheduled cell in the scheduled cell group in the first scheduling relationship is the same.

[0133] In some embodiments, in the first scheduling relationship, the first parameter corresponding to the scheduling cell of each of the at least two first cells is the same as or not the same as the first parameter.

[0134] At this time, the terminal device supports capability D: in the scheduled cell group, the first parameter corresponding to the scheduling cell corresponding to each scheduled cell in the first scheduling relationship is not the same first parameter.

[0135] In the embodiment of the present application, capability C is the basic capability of the terminal device, and capability D is a higher-level capability than capability C. When the terminal device supports capability D, it can also support capability C.

[0136] When the terminal device supports capability D, the first parameter corresponding to the scheduling cell corresponding to each scheduled cell in the first scheduling relationship in the scheduled cell group may be the same first parameter or may not be the same first parameter.

[0137] In one example, the cells configured with the terminal device include: cell 1, cell 2, cell 3, cell 4, cell 5 and cell 6, the SCS corresponding to cell 1 and cell 3 is 15kHz, the SCS corresponding to cell 2, cell 4 and cell 6 is 60kHz, and the SCS corresponding to cell 5 is 30kHz. The scheduled cells corresponding to cell 1 include: cell 1 and cell 2, the scheduled cells corresponding to cell 3 include: cell 3 and cell 4, and the scheduled cells corresponding to cell 5 include cell 5 and cell 6. If the terminal device supports capability D, the scheduled cell group may be a combination of cells in {cell 1, cell 2, cell 3 and cell 4} and cells in {cell 4, cell 5}, such as: cell 1+cell 5, cell 2+cell 6, cell 3+cell 4+cell 5, etc. The scheduled cell combination may also include: a combination of multiple cells in {cell 1, cell 2, cell 3 and cell 4}, and a combination of multiple cells in {cell 5, cell 6}, such as: cell 1+cell 2, cell 3+cell 4, cell 5+cell 6.

[0138] In an embodiment of the present application, when one DCI can schedule channels of multiple scheduled cells, that is, when one scheduling cell schedules a scheduled cell group, the first parameter corresponding to the scheduling cell corresponding to each scheduled cell in the scheduled cell group is not the same first parameter, and the restriction that the first parameter corresponding to the scheduling cell corresponding to different scheduled cells in the scheduled cell group is not the same first parameter can be lifted, which can improve the configuration / scheduling flexibility of the carrier or cell and reduce the PDCCH blockage probability.

[0139] In some embodiments, the terminal device reports second capability indication information to the network device.

[0140] At this time, the network device receives the second capability indication information sent by the terminal device.

[0141] When the terminal device supports capability D, it may report the second capability indication information to the network device. When the network device receives the second capability indication information reported by the terminal device, it determines that the scheduling cells corresponding to each scheduled cell in the scheduled cell group supported by the terminal device are not the same scheduling cells. When the network device sends a DCI scheduling channel of the scheduled cell group to the terminal device, the first parameter corresponding to the scheduling cell corresponding to each scheduled cell in the scheduled cell group in the first scheduling relationship is not the same first parameter.

[0142] In an embodiment of the present application, the second capability indication information indicates that the terminal device supports at least one of the following:

[0143] One DCI schedules channels of at least two scheduled cells, and the first parameters corresponding to the scheduling cells corresponding to each of the at least two scheduled cells are not the same first parameter;

[0144] A scheduled cell is scheduled by at least two scheduling cells, and the first parameters corresponding to the at least two scheduling cells are not the same first parameter.

[0145] When the terminal device supports a DCI scheduling of a channel of at least two scheduled cells, and the first parameter corresponding to the scheduling cell corresponding to each of the at least two scheduled cells is not the same first parameter, the terminal device is considered to support a third capability, and the third capability is the capability of a DCI scheduling of a channel of at least two scheduled cells, and the first parameter corresponding to the scheduling cell corresponding to each of the at least two scheduled cells is not the same first parameter.

[0146] When the terminal device supports a scheduled cell being scheduled by at least two scheduling cells, and the first parameters corresponding to the at least two scheduling cells are not the same first parameter, the terminal device is considered to support the second capability, and the second capability is the capability that a scheduled cell is scheduled by at least two scheduling cells, and the first parameters corresponding to the at least two scheduling cells are not the same first parameter. At this time, a scheduled cell can correspond to at least two scheduling cells with different first parameters.

[0147] In the embodiment of the present application, the capability indicated by the second capability indication information may also include a variation of the fourth capability, for example: the scheduled cell supports not only self-scheduling but also cross-carrier scheduling, and the first parameter corresponding to the scheduled cell and the scheduling cell of the cross-scheduling is different. In the embodiment of the present application, no limitation is imposed on the variation of the fourth capability.

[0148] In some embodiments, the first scheduling relationship is configured by the network device through high-layer signaling. The first scheduling relationship may be configured through cross-carrier scheduling configuration information.

[0149] In an embodiment of the present application, the second scheduling relationship between a scheduling cell and a scheduled cell group can be configured by the network device through high-level signaling, or can be configured by the terminal device based on the first scheduling relationship configured by high-level signaling, thereby forming a third scheduling relationship based on the second scheduling relationship and the first scheduling relationship.

[0150] In some embodiments, the terminal device receives cross-cell scheduling configuration information sent by the network device, and the cross-cell scheduling configuration information is used to configure a scheduling cell corresponding to a scheduled cell. The cross-cell scheduling configuration information is used to indicate a third scheduling relationship, and the third scheduling relationship includes a first scheduling relationship and / or a second scheduling relationship. In the first scheduling relationship, one DCI schedules a channel of a scheduled cell; in the second scheduling relationship, one DCI schedules channels of at least two scheduled cells.

[0151] In some embodiments, the terminal device determines the maximum number of candidate physical downlink control channels PDCCH or the maximum number of non-overlapping control channel elements CCE to be monitored on the activated bandwidth part BWP of the second cell or the second cell group based on the adjustment coefficient, and the second cell group includes at least two second cells, and the first parameters corresponding to the at least two second cells are the same, and the second cell is any scheduling cell.

[0152] Optionally, the configuration method of the adjustment coefficient includes:

[0153] Configuration method 1. Pre-agreed by agreement; or,

[0154] Configuration method 2: configuring the network device.

[0155] When the configuration mode of the adjustment coefficient is configuration mode 2, the network device performs the following processing:

[0156] The network device configures an adjustment coefficient to the terminal device, and the adjustment coefficient is used to determine the maximum number of candidate physical downlink control channels PDCCH or the maximum number of non-overlapping control channel elements CCE monitored by the terminal device on an activated BWP in a second cell or a second cell group, wherein the second cell group includes at least two second cells corresponding to the same first parameter, and the second cell is any scheduling cell.

[0157] In an embodiment of the present application, the scheduling cell is capable of scheduling the scheduled cell group, and the terminal device determines, based on the adjustment coefficient, the maximum number of candidate physical downlink control channels PDCCH, i.e., PDCCHcandicate, or the maximum number of non-overlapping CCEs to be monitored on the activated BWP of the second cell or the second cell group.

[0158] Here, the second cell is any scheduling cell in at least one scheduling cell in the third scheduling relationship of the cell configured by the terminal device, and the at least one scheduling cell includes a third cell, and the third cell is a cell carrying the first DCI. When the third scheduling relationship includes multiple second cells with the same first parameter, the multiple second cells constitute a second cell group.

[0159] In one example, the cells configured with the terminal device include: cell 1, cell 2, cell 3, cell 4, cell 5 and cell 6, the SCS corresponding to cell 1 and cell 3 is 15kHz, the SCS corresponding to cell 2, cell 4 and cell 6 is 60kHz, the SCS corresponding to cell 5 is 30kHz, the scheduling cells include: cell 1, cell 3 and cell 5, the second cell includes: cell 5, and the second cell group includes {cell 1, cell 3}.

[0160] Optionally, after the terminal device determines the maximum number of candidate PDCCHs to be monitored on the activated BWP of the second cell or the second cell group based on the adjustment parameter, the number of blind detections of PDCCHs on the activated BWP of the second cell or the second cell group does not exceed the maximum number of candidate PDCCHs determined based on the adjustment coefficient.

[0161] Optionally, after the terminal device determines the maximum number of non-overlapping CCEs monitored on the activated BWP of the second cell or the second cell group based on the adjustment parameter, the number of non-overlapping CCE detections on the activated BWP of the second cell or the second cell group does not exceed the maximum number of non-overlapping CCEs determined based on the adjustment coefficient and the maximum number of the maximum non-overlapping CCEs monitored on the activated BWP of one cell.

[0162] In the embodiment of the present application, by introducing the adjustment coefficient, it is ensured that the PDCCH detection capability is allocated according to the data transmission requirements of different scheduled cells.

[0163] In some embodiments, the adjustment coefficient corresponds to the second cell or the second cell group, or the adjustment coefficient corresponds to a first parameter corresponding to the second cell or the second cell group, the first parameter is the subcarrier spacing, or the first parameter is used to define the subcarrier spacing and / or the cyclic prefix.

[0164] In the embodiment of the present application, the adjustment coefficient may be based on a cell or a cell group, or a first parameter configuration, namely, per-(numerology of) scheduling cell(s).

[0165] Optionally, the adjustment coefficient is configured according to the second cell or the second cell group, and there is a corresponding relationship between the adjustment coefficient and the second cell or the second cell group, then the adjustment coefficient corresponding to each second cell or the second cell group is configured respectively. At this time, the terminal device can determine the adjustment coefficient according to the second cell or the second cell group.

[0166] In one example, the cells configured with the terminal device include: cell 1, cell 2, cell 3, cell 4, cell 5 and cell 6, the SCS corresponding to cell 1 and cell 3 is 15kHz, the SCS corresponding to cell 2, cell 4 and cell 6 is 60kHz, and the SCS corresponding to cell 5 is 30kHz. The scheduling cells include: cell 1, cell 3 and cell 5, then the second cell includes: cell 1, cell 3, cell 5, and the adjustment coefficients corresponding to cell 1, cell 3 and cell 5 are: adjustment coefficient 1, adjustment coefficient 2, adjustment coefficient 3 respectively.

[0167] Optionally, the adjustment coefficient is configured according to the first parameter, and there is a corresponding relationship between the adjustment coefficient and the first parameter, and the adjustment coefficient of each first parameter is configured separately. At this time, the terminal device can determine the adjustment coefficient according to the first parameter corresponding to the second cell or the second cell group.

[0168] In one example, the cells configured with the terminal device include: cell 1, cell 2, cell 3, cell 4, cell 5 and cell 6. The SCS corresponding to cell 1 and cell 3 is 15kHz, the SCS corresponding to cell 2, cell 4 and cell 6 is 60kHz, the SCS corresponding to cell 5 is 30kHz, the adjustment coefficient corresponding to 15kHz is adjustment coefficient 4, the adjustment coefficient corresponding to 30kHz is adjustment coefficient 5, and the adjustment coefficient corresponding to 60kHz is adjustment coefficient 6.

[0169] In an embodiment of the present application, a reference adjustment coefficient γ may be set. In this case, the adjustment coefficient may be the product of the reference adjustment coefficient γ and the reference multiple n. Different second cells or second cell groups, or different first parameters, may correspond to different adjustment multiples n.

[0170] In the embodiment of the present application, the adjustment coefficient is configured based on the scheduling cell or the scheduling cell group, or the first parameter, so that signaling overhead can be saved and the PDCCH detection capability allocation is simple.

[0171] In some embodiments, the adjustment coefficient is used to adjust a first quantity, where the first quantity is the number of scheduled cells corresponding to the second cell or the second cell group, or the first quantity is the number of scheduled cells corresponding to a second parameter, where the second parameter is the first parameter corresponding to the second cell or the second cell group.

[0172] The first quantity can be expressed as That is, the first parameter corresponds to the number of scheduled cells corresponding to the scheduling cell or scheduling cell group j. To determine or

[0173] In one example, if Figure 8As shown, the scheduled cells include: cell 1, cell 3 and cell 5, the SCS of cell 1 and cell 3 is 15kHz, and the SCS of cell 5 is 30kHz. For the second cell group composed of cell 1 and cell 3, the first number is the number of scheduled cells corresponding to cell 1 and cell 3: 4, and for the second cell group composed of cell 5, the first number is the number of scheduled cells corresponding to cell 5: 2.

[0174] In one example, if Figure 8 As shown, the scheduled cells include: cell 1, cell 3 and cell 5. The SCS of cell 1 and cell 3 is 15kHz, and the SCS of cell 5 is 30kHz. For 15kHz, the corresponding first number is the number of scheduled cells corresponding to cell 1 and cell 3: 4. For 30kHz, the first number is the number of scheduled cells corresponding to cell 5: 2.

[0175] Here, the adjustment method of adjusting the first quantity by the adjustment coefficient may include performing at least one of the following operations on the adjustment coefficient and the first data: addition, subtraction, multiplication and division, etc. In the embodiment of the present application, no limitation is imposed on the adjustment method.

[0176] In the embodiment of the present application, the scheduling cell corresponding to the scheduled cell group may be any scheduling cell in the first scheduling relationship.

[0177] In one example, the cells configured with the terminal device include: cell 1, cell 2, cell 3, cell 4, cell 5 and cell 6. Cell 1 schedules cell 1 and cell 2, cell 3 schedules cell 3 and cell 4, and cell 5 schedules cell 5 and cell 6. The scheduled cell of cell 1+cell 3 can be cell 1, cell 3 or cell 5.

[0178] In the embodiment of the present application, after the second scheduling relationship is added on the basis of the first scheduling relationship, the channel corresponding to the scheduled cell group is undertaken by the corresponding scheduling cell, which may affect the maximum value of the number of candidate PDCCHs and non-overlapping CCEs monitored on the activation BWP of the scheduling cell corresponding to the first scheduled cell or the activation BWP of the scheduling cell corresponding to the scheduled cell group. The terminal device can determine the adjustment coefficient based on the scheduling cell or the adjustment cell group, or the first parameter corresponding to the scheduling cell or the scheduling cell group, and adjust each first quantity based on the determined adjustment coefficient, so as to determine the maximum value of the number of candidate PDCCHs and non-overlapping CCEs monitored on the activation BWP of each scheduling cell or scheduling cell group based on the adjusted first quantities. Among them, the first scheduled cell is a scheduled cell in the scheduled cell group.

[0179] In the embodiment of the present application, the adjustment strategy for adjusting the first quantity by adjusting the adjustment coefficient may include one or more of the following two adjustment strategies:

[0180] Adjustment strategy 1, the adjustment coefficient is used to adjust the first number to a second number, the second number is greater than or equal to the first number, the second cell or the second cell group includes a third cell, and the third cell is used to carry the first DCI.

[0181] Adjustment strategy 2: The adjustment coefficient is used to adjust the first number to a third number, the third number is less than or equal to the first number, the second cell or the second cell group does not include a third cell, and the third cell is used to carry the first DCI.

[0182] In adjustment strategy 1, if the second cell or the second cell group includes the third cell, then the second cell or the second cell group assumes the channels of at least two first cells, that is, assumes the channels of the scheduled cell group. In one example, cell 1 schedules the cell group: cell 1 + cell 5, the SCS of cell 1 is 15kHz, and the 15kHz scheduled cell also includes cell 3, then the second cell group composed of cell 1 and cell 3 assumes the channels of cell 1 + cell 3. In the case where the scheduled cells corresponding to the second cell or the second cell group include all the first scheduled cells, the data scheduled by the second cell or the second cell group remains unchanged, and at this time, the second number is equal to the first number; in the case where the scheduled cells corresponding to the second cell or the second cell group do not include any of the first scheduled cells, the data scheduled by the second cell or the second cell group increases, and at this time, the second number is greater than the first number. For example: Based on the above example, when the scheduling cell corresponding to cell 1 is cell 1 and the scheduling cell corresponding to cell 5 is cell 3, the data scheduled by the second cell group composed of cell 1 and cell 3 remains unchanged. When the scheduling cell corresponding to cell 1 is cell 1 and the scheduling cell corresponding to cell 5 is cell 5, the data scheduled by the second cell group composed of cell 1 and cell 3 is increased by adding the channel of cell 5.

[0183] In adjustment strategy 2, if the second cell or the second cell group does not include the third cell, the second cell or the second cell group does not bear the channels of at least two first cells, that is, it does not bear the channels of the scheduled cell group. In one example, cell 1 schedules the cell group: cell 1 + cell 5, the SCS of cell 1 is 15kHz, and the 15kHz scheduling cell also includes cell 3, then the second cell group composed of cell 1 and cell 3 bears the channels of cell 1 + cell 3, and the second cell configured by the terminal device also includes: cell 5 and cell 7, the scheduled cells corresponding to cell 5 include: cell 5 and cell 6, and the scheduled cells corresponding to cell 7 include: cell 7 and cell 8, then the second cell cell 5 and the second cell cell 7 do not bear the data of cell 1 and cell 5. In the case where the scheduled cells corresponding to the second cell or the second cell group do not include all the first scheduled cells, the data scheduled by the second cell or the second cell group remains unchanged, and at this time, the third number is equal to the first number; in the case where the scheduled cells corresponding to the second cell or the second cell group include any scheduled cell, the channels scheduled by the second cell or the second cell group are reduced, and at this time, the third number is less than the first number. For example: Based on the above example, the scheduled cells corresponding to cell 7 are still cell 7 and cell 8, and the scheduled data remains unchanged. Cell 5 is the scheduled cell, and part of its data is scheduled by cell 1. Then the data of the scheduling cell 5 corresponding to cell 5 is reduced.

[0184] In one example, the cells configured with the terminal device include: cell 1, cell 2, cell 3, cell 4, cell 5 and cell 6, cell 1 schedules cell 1 and cell 2, cell 3 schedules cell 3 and cell 4, cell 5 schedules cell 5 and cell 6, and cell 1 and cell 3 are the second cell group 1, cell 5 is a second cell 2, when cell 1 and cell 3 constitute a scheduled cell group, cell 1 + cell 3 can be scheduled by cell 1 or cell 3, when cell 1 + cell 3 is scheduled by cell 1 or cell 3, the second cell group 1 still schedules data of each cell in {cell 1, cell 2, cell 3, cell 4}, therefore, the data scheduled by the second cell group 1 remains unchanged, the second number corresponding to the second cell group 1 is equal to the first number corresponding to the second cell group 1, the scheduled cells corresponding to the second cell 2, i.e., cell 5, are cell 5 and cell 6, and the scheduled data remains unchanged, therefore, the second number corresponding to the second cell 2 remains unchanged, and the third number corresponding to the second cell 2 is equal to the first number corresponding to the second cell 2.

[0185] In one example, the cells configured by the terminal device include: cell 1, cell 2, cell 3, cell 4, cell 5 and cell 6, cell 7 and cell 8, cell 1 schedules cell 1 and cell 2, cell 3 schedules cell 3 and cell 4, cell 5 schedules cell 5 and cell 6, cell 7 schedules cell 7 and cell 8, and cell 1 and cell 3 are the second cell group 1, cell 5 is the second cell 2, and cell 7 is the second cell 3. When cell 1 and cell 5 constitute a scheduled cell group, when cell 1+cell 5 is scheduled by cell 5, and part of the data of cell 1 is scheduled by cell 5, then the second cell group 1 schedules the data of each cell in {cell 1, cell 2, cell 3, cell 4} , part of the data of cell 1 is scheduled by cell 5, therefore, the data scheduled by the second cell group 1 decreases, then the third number corresponding to the second cell group 1 is smaller than the first number corresponding to the second cell group 1, the scheduled cells corresponding to the second cell 2, i.e., cell 5, are cell 5 and cell 6, and also include part of the data of cell 1, then the data scheduled by cell 5 increases, therefore, the second number corresponding to the second cell 2 is larger than the first number corresponding to the second cell 2, the scheduled cells corresponding to cell 7 are cell 7 and cell 8, then the data scheduled by cell 7 is not affected by cell 1+cell 5, then the third number corresponding to cell 7, i.e., the second cell 3, is equal to the first number corresponding to the second cell 3.

[0186] In some embodiments, among the at least two first cells, the first parameter corresponding to the scheduling cell corresponding to each first cell is not the same first parameter, and the first parameter is the subcarrier spacing, or the first parameter is used to define the subcarrier spacing and / or the cyclic prefix.

[0187] In an embodiment of the present application, when the first parameters corresponding to the scheduling cells corresponding to each first cell are the same, the number of scheduled cells corresponding to the second cell or the second cell group does not change, and the scheduled cell group does not cause the data borne by each second cell or the second cell group to change, so there is no need to adjust the first number corresponding to each second cell or the second cell group.

[0188] In at least two first cells, the first parameter corresponding to each first cell is not the same first parameter, and the scheduled cell group affects the number of scheduled cells corresponding to some second cells or second cell groups, then the first number corresponding to each second cell or second cell group is adjusted according to the adjustment coefficient.

[0189] In an embodiment of the present application, when the third cell is not a scheduled cell in the first scheduling relationship, the third cell can be used as a new scheduling cell. At this time, the first number value corresponding to the third cell can be considered as a default value, such as: 0 or 1.

[0190] The following is a further description of the wireless communication method provided in the embodiments of the present application.

[0191] The terminal receives DCI sent by the network side, where the DCI is used to schedule at least two (N) data channels (PDSCH or PUSCH), where the N data channels correspond to M carriers / serving cells, and M is less than or equal to N.

[0192] The terminal receives cross-carrier scheduling configuration information sent by the network side, where the cross-carrier scheduling configuration information is used to configure a scheduling carrier corresponding to a scheduled carrier.

[0193] 1. The terminal does not expect that the scheduled carriers corresponding to the M carriers are different, that is, only when the scheduled carriers corresponding to the M carriers are the same, the data of the M carriers can be scheduled by the same DCI;

[0194] a. Define a second terminal capability, where the first terminal capability is used to indicate that the terminal supports the above-mentioned "one DCI scheduling data channels of multiple carriers" function, and the scheduling carriers corresponding to the multiple carriers are not the same scheduling carrier, or define a first terminal capability, where the first terminal capability is used to indicate that the terminal supports a scheduled carrier being scheduled by more than one scheduling carrier.

[0195] It is worth noting that the first terminal capability includes all capabilities that can indicate that a scheduled carrier is scheduled by more than one scheduling carrier. For example, PCell can be self-scheduled by default. Then, after supporting the cross-carrier scheduling capability from SCell to PCell, it is equivalent to supporting that PCell can be scheduled by multiple carriers, that is, the cross-carrier scheduling capability of SCell scheduling PCell is also a variation of the above-mentioned first terminal capability.

[0196] When the terminal does not report the first terminal capability and / or the second terminal capability, the terminal does not expect that the scheduled carriers corresponding to the M carriers are not the same scheduled carrier;

[0197] When the terminal reports the first terminal capability and / or the second terminal capability, the terminal may support that the scheduled carriers corresponding to the M carriers are not the same scheduled carrier.

[0198] In one example, the network side configures cell 1 to cell 6 for the terminal, where the scheduling relationship of cell 1 to cell 6 is as follows: Figure 7 As shown, the scheduling cell of cell 1 and cell 2 is cell 1, the scheduling cell of cell 3 and cell 4 is cell 3, and the scheduling cell of cell 5 and cell 6 is cell 5. Figure 7The scheduling relationship shown, when supporting the function of a DCI scheduling data channels of multiple scheduled cells, the multiple scheduled cells can be: 1) a subset of {cell 1, cell 2}, or, 2) a subset of {cell 3, cell 4}, or, 3) a subset of {cell 5, cell 6}. In other words, a DCI scheduling is not supported, such as the following cell combinations: cell 1+cell 3, cell 1+cell 5, etc.

[0199] If the scheduling cells corresponding to the M carriers are not the same scheduling cell, then there must be some cells in the M carriers that are scheduled by more than one scheduling cell at the same time. Figure 7 The scheduling relationship shown in FIG. 1 shows that if cell 1+cell 5 can be scheduled simultaneously, the following situations may exist: 1) cell 1 can be scheduled by cell 1 and cell 5 at the same time, or 2) cell 5 can be scheduled by cell 1 and cell 5 at the same time. Since NR R15 / 16 only supports one scheduled cell to be scheduled by one scheduling cell, supporting one scheduled cell to be scheduled by more than one scheduling cell will introduce additional implementation complexity.

[0200] 2. The terminal does not expect that the subcarrier spacing of the scheduling cells corresponding to the M cells is not the same subcarrier spacing or the numerology is not the same numerology, that is, only when the subcarrier spacing or numerology of the scheduling cells corresponding to the M cells is the same, the data of the M cells can be scheduled by the same DCI;

[0201] a. Define a fourth terminal capability, which is used to indicate that the terminal supports the above-mentioned "one DCI schedules data channels of multiple cells" function, and the subcarrier spacing of the scheduling carriers corresponding to the multiple cells is not the same subcarrier spacing or the numerology is not the same numerology, or the third terminal capability is used to indicate that the terminal supports a scheduled cell being scheduled by more than one scheduling cell, and the subcarrier spacing of the scheduling cell is not the same subcarrier spacing or the numerology is not the same numerology. It is worth noting that the third terminal capability includes all deformation capabilities that can indicate the above-mentioned functions. For example, PCell can be self-scheduled by default, then it supports cross-carrier scheduling capability from SCell to PCell, and after the subcarrier spacing of SCell and PCell is different, it is equivalent to supporting a cell being scheduled by more than one cell with different subcarrier spacing, that is, the cross-carrier scheduling capability of SCell scheduling PCell (SCell and PCell subcarrier spacing are different) is also a deformation of the above-mentioned third terminal capability:

[0202] i. When the terminal does not report the third terminal capability and / or the fourth terminal capability, the terminal does not expect that the subcarrier spacing of the scheduling cells corresponding to the M cells is not the same subcarrier spacing or the numerology is not the same numerology;

[0203] ii. When the terminal reports the third terminal capability and / or the fourth terminal capability, the terminal may support that the subcarrier spacing of the scheduling cells corresponding to the M cells is not the same subcarrier spacing or the numerology is not the same numerology.

[0204] In one example, the network side configures cell 1 to cell 6 for the terminal, where the subcarrier spacing / numerology and scheduling relationship of cell 1 to cell 6 are as follows: Figure 8 As shown, the scheduling cells include: cell1, cell3 and cell5, wherein the subcarrier spacing of cell1 and cell3 is 15kHz, the number of scheduled cells corresponding to cell1 is 2, the number of scheduled cells corresponding to cell3 is 2, then the data of the scheduled cell corresponding to 15kHz is 4, the subcarrier spacing of cell5 is 30kHz, the number of scheduled cells corresponding to cell3 is 2, then the number of scheduled cells corresponding to 30kHz is 2. According to the method of this scheme, when supporting the function of a DCI scheduling data channel of multiple cells, the multiple cells can be: 1) a subset of {cell 1, cell 2, cell 3, cell 4}, or, 2) a subset of {cell 5, cell 6}, in other words, a DCI scheduling, such as the following cell combinations, is not supported: cell 1+cell 6, cell 1+cell 5, etc.

[0205] In a multi-carrier system, the PDCCH detection capability is divided to maximize the reuse of existing mechanisms, and backward compatibility is good. The specific reasons are: and What is affected is: the number of scheduled cells corresponding to the scheduling cells with the same subcarrier spacing. If the subcarrier spacing of the scheduling cells corresponding to the M cells is the same, the calculation of the PDCCH detection capability of the terminal on all scheduling cells with a subcarrier spacing of μ is not affected by the "one DCI scheduling multiple scheduled cells" function. From the above, if the M cells are a subset of 1) {cell 1, cell 2, cell 3, cell 4}, or 2) a subset of {cell 5, cell 6}, then the number of scheduled cells corresponding to the scheduling cells (cell 1 and cell 3) with a subcarrier spacing of 15kHz is the same as the number of scheduled cells corresponding to the scheduling cells (cell 1 and cell 3) with a subcarrier spacing of 15kHz under "one CDI scheduling a channel of a scheduled cell", which is still 4 (cell 1~cell4); if the M cells are cell 1+cell 5, then the number of scheduled cells corresponding to the scheduling cells (cell 1 and cell 3) with a subcarrier spacing of 15kHz is 4 (cell 1~cell 4). 4), or 5 (cell 1 to cell 5), or other values, require discussion and complex design mechanisms. Therefore, limiting the scheduling carrier numerology corresponding to the M cells to be the same can simplify the design of PDCCH detection capability division.

[0206] 3. The subcarrier spacing or numerology of the scheduling cells corresponding to the M cells may be the same or different. When the total capacity of multiple carriers is divided, an adjustment coefficient is introduced. The adjustment coefficient is used to adjust the counting result (such as multiplying, dividing, adding, or subtracting the scheduling coefficient) when counting the scheduled cells according to the numerology of the scheduling cells. The scheduling coefficient may be agreed upon by the protocol or configured by high-level signaling. In particular, the adjustment parameter may be agreed upon / configured per-(numerology of) scheduling cell. The configuration of the adjustment system may also be extended to configure only one reference adjustment coefficient γ. When the scheduling carrier numerology is different, the scheduled cell count may be (+, -, ×, ÷) n times γ, where n may be configured or determined according to the configured scheduled cell combination. Furthermore, the adjustment coefficient is introduced only when the numerology of the scheduling cells corresponding to the M cells is different.

[0207] In one example, the network side configures cell 1 to cell 6 for the terminal, where the subcarrier spacing / numerology and scheduling relationship of cell 1 to cell 6 are as follows: Figure 8 As shown, in Figure 8 On the basis of Fig. 9As shown, a scheduled cell combination cell 1+cell 5 is added, and the network side configures the scheduled cell combination cell 1+cell 5 to be scheduled by cell 5. The maximum number of carriers detected by the PDCCH reported by the terminal is 2.

[0208] When the terminal device does not support scheduling multiple carriers with one DCI:

[0209] For each scheduled carrier, the terminal device detects PDCCH candidates on the scheduled carrier for no more than in, The values ​​of are shown in Table 1. The calculation method is as follows:

[0210] Among the 6 carriers, the number of scheduled cells corresponding to the 15kHz SCS scheduling cell (cell 1, cell 3) is 4 (cell 1 to cell 4), and the number of scheduled cells corresponding to the 30kHz SCS scheduling cell (cell 5) is 2 (cell 5 to cell 5). and They are:

[0211]

[0212]

[0213] When supporting one DCI scheduling multiple cells:

[0214] For each scheduled cell, the terminal blindly detects PDCCH candidates no more than in, The values ​​of are shown in Table 1. The calculation method is as follows:

[0215] Since the network side configures cell 1+cell 5 to be scheduled by cell 5, it is equivalent to that a part of the data from cell 1 will be scheduled by cell 5 (there is no one-to-many scheduling, that is, when the scheduling cell schedules the scheduled cell group, all the data of cell 1 is scheduled by cell 1). Therefore, among the 6 cells, the number of scheduled cells corresponding to the scheduling cells of 15kHz SCS (cell 1, cell 3) should be reduced from 4, and the number of scheduled cells corresponding to the scheduling cell of 30kHz SCS (cell 5) should be increased from 2:

[0216] Assuming that the scheduling cell numerology indicates 15kHz and 30kHz respectively, the corresponding adjustment coefficients are α and β respectively, then and They are:

[0217]

[0218]

[0219] In the example again, it is more appropriate to take β=-α.

[0220] Here, “+” is just an example, and “+, -, ×, ÷” may also be used.

[0221] Here, by involving the scheduling cell corresponding to the scheduled cell in the scheduled cell group, the following technical effects can be achieved:

[0222] 1) There is no restriction on the scheduling carriers of the M cells, and the configuration / scheduling flexibility is the highest;

[0223] 2) The introduction of the adjustment coefficient ensures that the PDCCH detection capability is allocated according to the data transmission requirements of different scheduled cells

[0224] 3) Compared with configuring the adjustment coefficient per-scheduled cell, per-scheduling cell or per-scheduling cell subcarrier spacing saves signaling overhead and is simpler.

[0225] It should be noted that in the wireless communication method provided in the embodiment of the present application, the concepts of "cell" and "carrier" are the same and can be replaced with each other.
