The base station is not limited to a specific technical term, and it should be noted that only a base station in an NR system is taken as an example in the embodiments of the present application, but the specific type of the base station is not limited.

[0052] For ease of understanding, the related content involved in the embodiments of the present application is described as follows:

[0053] Cell scheduling:

[0054] The 5th-Generation (5G) New Radio (NR) system supports configuring one or multiple carriers (component carriers, CCs) or cells for a user equipment (UE). When a UE is configured in a single carrier mode or a self-scheduling mode under carrier aggregation (CA), each CC or cell can be configured with multiple control resource sets (CORESETs) and multiple search spaces (SSs), including common search spaces (CSSs) and UE-specific search spaces (USSs). The network can flexibly configure the number of blind decodes for each search space set, and the CORESETs can be flexibly associated with the search space sets. The UE decodes the downlink control information (DCI) by blindly detecting the physical downlink shared channel (PDCCH) using various radio network temporary identities (RNTIs) according to the configured CORESETs and SSs, to obtain the scheduling information of each cell. Each DCI schedules the data of one cell.

[0055] If the channel quality of some cells is not good enough or the channel blocking probability is high, the network can configure the UE with cross-carrier scheduling, i.e., configuring the control channel in other cells with better channel quality, e.g., a primary cell (PCell), to schedule the data of other cells, e.g., secondary cells (SCells). The subcarrier spacing (SCS) of the scheduling cell and the scheduled cell can be the same or different. The scheduling cell can be in a self-scheduling mode, in which case the cell only schedules itself. If the scheduling cell is configured with cross-carrier scheduling, it can also schedule one or more scheduled cells other than itself. The scheduled cell has no PDCCH of its own and can only be scheduled by one scheduling cell. In the 15th release (Release 15) NR system, one cell can only be scheduled by one scheduling cell, i.e., it can only be self-scheduled or scheduled by another cell, and the PCell can only be scheduled by the PCell itself.

[0056] To reduce the implementation complexity of UE, NR system specifies the maximum processing capability of UE to blindly detect PDCCH of one CC or cell. The capability contains two parts: the maximum number of PDCCH candidates blindly detected in one slot, and the maximum number of channel estimation, i.e. the number of non-overlapping control channel elements (CCEs), required by UE to perform blind detection. The maximum processing capability of UE is related to the SCS of the CC or cell blindly detected, i.e. the processing capability in one slot is different under different SCS, as shown in Table 1 to Table 3. In addition, UE can also report the maximum blind detection capability supported by it in CA.

[0057] In addition, to reduce the implementation complexity of UE, NR system specifies the DCI size budget of UE, i.e. specifies that for each scheduled cell, the maximum number of different sizes of DCI formats monitored by UE is 4, and the maximum number of different sizes of DCI formats in USS is 3.

[0061]

[0062] Table 3 Maximum number of non-overlapping CCEs per slot under different SCS configurations in single cell

[0063]

[0064] It should be noted that, for the purpose of enhancing the coverage of control channel, PCell is generally deployed in a low frequency carrier, as shown in Figure 2 . The bandwidth of low frequency carrier is insufficient, and has been largely deployed to other series, for example, Long Term Evolution (LTE). At this time, it is necessary to realize the scheduling of PCell through SCell to solve the problem of limited control channel capacity of PCell, and reduce the PDCCH overhead of control channel, as shown in Figure 3 . However, Release 15 NR system does not support the scheduling of PCell using SCell, and simultaneously monitoring PDCCH from two scheduling cells will greatly increase the complexity and power consumption of demodulation and implementation of UE, and raise the hardware product of UE, which is not conducive to the implementation of UE.

[0065] Overbooking:

[0066] When multiple search space sets (SS sets) are configured, the number of PDCCH candidates / CCEs will vary at different times because the monitoring spaces of different SS sets are configured independently. Therefore, it is permissible for the base station (BS) to configure the total number of PDCCH candidates / CCEs on each slot to exceed the user's capacity; this is called overbooking.

[0067] Based on the configuration, SS sets are mapped on each slot according to the following rules:

[0068] (1) Prioritize mapping CSS sets, that is, prioritize allocating blind detection resources;

[0069] (2) Map USS, which means allocating blind detection resources to USS. Mapping or allocating in ascending order of SS setID. If the number of PDCCH candidates / CCE exceeds the user's processing capacity limit, SS set will no longer be mapped or allocated.

[0070] Without the Overbooking feature, the configuration of SS set will be limited by the worst case, which means that the total number of PDCCH candidates / CCEs after the SS set mapping on each slot does not exceed the user's capacity. Therefore, BS cannot maximize the user's blind detection capability and will lead to multi-user blocking.

[0071] For example, such as Figure 4 As shown, taking the mapping of CSS, USS#1, and USS#2 to CCE as an example, the monitoring time configuration for CSS, USS#1, and USS#2 is as follows: Figure 4 For slots 1, 5, and 9, after mapping CSS and USS#1, it is impossible to further map USS#2, which exceeds the user's capabilities.

[0072] The control channel monitoring method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0073] Please see Figure 5 , Figure 5 This is a flowchart of a control channel monitoring method provided in an embodiment of this application. This method can be executed by a terminal, such as... Figure 5 As shown, it includes the following steps:

[0076] It should be noted that if the blind detection objects include at least two of the following: PDCCH candidate, CCE, DCI format, search space, monitoring occasion, span and CORESET, the channel monitoring budget (Budget) can include a limit value corresponding to each of the at least two, for example, if the blind detection objects include PDCCH candidate and CCE, the channel monitoring budget can include a limit value of the number of PDCCH candidates and a limit value of the number of CCEs, wherein the limit value can include an upper limit value or a lower limit value.

[0077] In an embodiment, the M cells can include the first cell, that is, the first cell can be self-scheduled or scheduled by other cells. For example, the primary cell can be self-scheduled or scheduled by the secondary cell. In this embodiment, the first channel monitoring budget can include at least one of the following: a channel monitoring budget corresponding to at least one of the M cells, a joint channel monitoring budget between at least two of the M cells. Alternatively, the first channel monitoring budget includes at least a channel monitoring budget corresponding to the first cell.

[0089] The joint channel monitoring budget between the at least two cells can also be referred to as a joint channel monitoring budget corresponding to any cell of the at least two cells. For example, the joint channel monitoring budget between Cell#1 and Cell#2 can also be referred to as a joint channel monitoring budget corresponding to Cell#1 or a joint channel monitoring budget corresponding to Cell#2. If the number of joint channel monitoring budgets is 1, the joint channel monitoring budget between the at least two cells can also be directly referred to as a joint channel monitoring budget.

[0090] The joint channel monitoring budget between the at least two cells can also be referred to as a joint channel monitoring budget corresponding to any cell of the at least two cells. For example, the joint channel monitoring budget between Cell#1 and Cell#2 can also be referred to as a joint channel monitoring budget corresponding to Cell#1 or a joint channel monitoring budget corresponding to Cell#2. If the number of joint channel monitoring budgets is 1, the joint channel monitoring budget between the at least two cells can also be directly referred to as a joint channel monitoring budget.

[0091] Optionally, the joint channel monitoring budget corresponding to the first cell can be a channel monitoring budget corresponding to the first cell; or the joint channel monitoring budget corresponding to the first cell can be a channel monitoring budget corresponding to the first cell when the first cell is a scheduled cell.

[0117] The first blind detection object number can be the number of blind detection objects in the first control resource that the terminal needs to allocate within the N1 time units; or the first blind detection object number can be the number of blind detection objects in the first control resource that the terminal needs to monitor within the N1 time units; or the first blind detection object number can be the number of blind detection objects in the first control resource that the terminal needs to allocate and monitor within the N1 time units.

[0118] For example, the number of PDCCH candidates or the number of CCEs in the first control resource that the terminal needs to monitor within the N1 time units is less than or equal to the channel monitoring budget corresponding to the first cell.

[0119] Optionally, the first blind detection object number can be reasonably configured by the network side device to ensure that it is less than or equal to the channel monitoring budget corresponding to the first cell, for example, the network side device can configure the number of blind detection objects in the first control resource within the N1 time units to be less than or equal to the channel monitoring budget corresponding to the first cell. Correspondingly, the terminal can not expect the first blind detection object number to be greater than the channel monitoring budget corresponding to the first cell, that is, the terminal expects the first blind detection object number to be less than or equal to the channel monitoring budget corresponding to the first cell.

[0120] Optionally, in the case that the second blind detection object number is greater than the channel monitoring budget corresponding to the first cell, the terminal can perform at least one of the following:

[0121] Discarding at least part of the blind detection objects of at least part of the control resources of the first control resource;

[0122] Performing the first operation on at least part of the blind detection objects of at least part of the control resources of the first control resource;

[0123] The second blind detection object number is the number of blind detection objects in the first control resource that the terminal needs to perform the first operation within the N2 time units, and N2 is a positive integer.

[0124] In this embodiment, the blind detection object can include, but is not limited to, at least one of the PDCCH candidate, the CCE, the DCI, and the like. The value of N2 can be preconfigured, pre-defined by a protocol, or configured by a network side device, and the like. The time unit can include, but is not limited to, a slot, an occasion, a time span, and the like. The N2 time units can be any N2 time units, or specific N2 time units.

[0125] The first blind detection object number can be the number of blind detection objects in the first control resource that needs to be allocated by the terminal within the N2 time units; or the first blind detection object number can be the number of blind detection objects in the first control resource that needs to be monitored by the terminal within the N2 time units; or the first blind detection object number can be the number of blind detection objects in the first control resource that needs to be allocated and monitored by the terminal within the N2 time units.

[0126] The discarding of at least part of the blind detection objects of at least part of the control resources of the first control resource, for example, can directly discard part of the control resources of the first control resource, and all blind detection objects of the corresponding part of the control resources are discarded, or can discard part of the blind detection objects of at least part of the control resources of the first control resource.

[0127] For example, if the number of PDCCH candidates / CCEs that need to be monitored by the terminal exceeds L1 on a certain time unit after allocating the PDCCH candidate / CCE of SS#X, the PDCCH candidate / CCE of SS#X is not allocated, or the part of the PDCCH candidate / CCE of SS#X that exceeds L1 is not allocated. Wherein, L1 is the channel monitoring budget corresponding to the first cell.

[0128] It should be noted that the discarding of at least part of the blind detection objects of at least part of the control resources of the first control resource can also be referred to as not monitoring or not mapping at least part of the blind detection objects of at least part of the control resources of the first control resource.

[0129] The performing of the first operation on at least part of the blind detection objects of at least part of the control resources of the first control resource, for example, can only perform the first operation on the blind detection objects of part of the control resources of the first control resource.

[0130] For example, if PDCCH candidates / CCEs of SS#X and SS#Y are allocated to the terminal in a certain time unit, the number of PDCCH candidates / CCEs that the terminal needs to monitor exceeds the channel monitoring budget L1 corresponding to the first cell, but if only PDCCH candidates / CCEs of SS#X are allocated, the number of PDCCH candidates / CCEs that the terminal needs to monitor does not exceed the channel monitoring budget L1 corresponding to the first cell, then only PDCCH candidates / CCEs of SS#X are allocated.

[0131] Optionally, N1 and N2 can be equal.

[0132] Optionally, the discarding the at least part of blind detection objects of the at least part of control resources of the first control resource can include one of the following:

[0133] Discarding at least part of blind detection objects of at least one USS of the first control resource;

[0134] Discarding at least part of blind detection objects of a specific control resource of the first control resource;

[0135] If the number of blind detection objects that the terminal needs to monitor is greater than the channel monitoring budget corresponding to the first cell after mapping the blind detection objects in the first sub-control resource according to the first preset rule, discarding at least part of blind detection objects of the first sub-control resource, the first sub-control resource including at least part of control resources in the first control resource.

[0136] In the embodiment, the specific control resource can be a specific USS.

[0137] The first preset rule can be reasonably set according to actual needs, for example, the first preset rule can be mapping the blind detection objects in the control resource in ascending order of the index of the control resource (for example, the index of the search space).

[0138] If the number of blind detection objects that the terminal needs to monitor is greater than the channel monitoring budget corresponding to the first cell after mapping the blind detection objects in the first sub-control resource according to the first preset rule, discarding at least part of blind detection objects of the first sub-control resource, for example, all blind detection objects of the first sub-control resource can be discarded, or only the part of blind detection objects of the first sub-control resource that exceeds the channel monitoring budget corresponding to the first cell can be discarded.

[0139] Optionally, the performing the first operation on at least part of blind detection objects of at least part of control resources of the first control resource can include one of the following:

[0140] Performing the first operation on at least part of blind detection objects of at least one CSS of the first control resource;

[0141] If the number of blind detection objects that the terminal needs to monitor is less than or equal to the channel monitoring budget corresponding to the first cell after the blind detection objects in the second sub-control resource are mapped according to the second preset rule, the first operation is performed on at least part of the blind detection objects of the second sub-control resource, and the second sub-control resource includes at least part of the control resources in the first control resource.

[0142] In the embodiment, the second preset rule can be reasonably set according to actual needs. For example, the second preset rule can be that the blind detection objects in the control resources are sequentially mapped from small to large according to the indexes of the control resources (for example, the indexes of the search spaces).

[0143] For example, at least part of the blind detection objects of at least one CSS of the first control resource can be allocated or monitored, or at least part of the blind detection objects of the second sub-control resource can be allocated or monitored.

[0144] Optionally, the second channel monitoring budget includes a channel monitoring budget corresponding to a second cell, and the second cell is a cell different from the first cell in the M cells.

[0145] In the embodiment, if the M cells include the first cell, that is, the first cell supports self-scheduling, the second cell can be any cell different from the first cell in the M cells; if the M cells do not include the first cell, that is, the first cell does not support self-scheduling, the second cell can be any cell in the M cells. Specifically, the terminal can allocate and / or monitor at least part of the control resources of the first control resource according to the channel monitoring budget corresponding to the second cell that schedules the first cell.

[0146] Optionally, the second cell is a cell different from the first cell in the M cells, and the first control resource includes any of the following:

[0147] The control resource of the second cell;

[0148] The control resource of the second cell can be used for the second cell to schedule the first cell;

[0149] The control resource of the second cell is specially used for the second cell to schedule the first cell;

[0150] The specific control resource on the second cell.

[0151] In the embodiment, the control resource of the second cell can be understood as any control resource of the second cell, for example, part or all of the SS on the second cell.

[0152] The control resource available for the second cell to schedule the first cell can include at least one of a control resource available for the second cell to schedule the first cell on the second cell, and a control resource available for the second cell to schedule the first cell on a cell other than the second cell among the M cells. For example, the control resource available for the second cell to schedule the first cell can be an SS available for the second cell to schedule the first cell.

[0153] The control resource dedicated to the second cell to schedule the first cell can include at least one of a control resource dedicated to the second cell to schedule the first cell on the second cell, and a control resource dedicated to the second cell to schedule the first cell on a cell other than the second cell among the M cells. For example, the control resource dedicated to the second cell to schedule the first cell can be an SS dedicated to the second cell to schedule the first cell.

[0154] The specific control resource on the second cell can be, for example, a specific SS on the second cell. It should be noted that the specific control resource on the second cell can be predefined by a protocol or indicated by a network side device.

[0155] Optionally, a third number of blind detection objects is less than or equal to a channel monitoring budget corresponding to the second cell, the third number of blind detection objects being a number of blind detection objects that the terminal needs to perform the first operation on the first control resource within N3 time units, the second cell being a cell different from the first cell among the M cells, and N3 being a positive integer.

[0156] In this embodiment, the blind detection object can include, but is not limited to, at least one of a PDCCH candidate, a CCE, a DCI, etc. The value of N3 can be preconfigured, predefined by a protocol, or configured by a network side device, etc. The time unit can include, but is not limited to, a slot, an occasion, or a time span, etc. The N3 time units can be any N3 time units, or can be specific N3 time units.

[0157] The third number of blind detection objects can be a number of blind detection objects that the terminal needs to allocate within the first control resource within N3 time units; or the third number of blind detection objects can be a number of blind detection objects that the terminal needs to monitor within the first control resource within N3 time units; or the third number of blind detection objects can be a number of blind detection objects that the terminal needs to allocate and monitor within the first control resource within N3 time units.

[0158] For example, the number of PDCCH candidates or CCEs in the first control resource that the terminal needs to monitor in N3 time units is less than or equal to the channel monitoring budget corresponding to the second cell.

[0159] Optionally, the network side device can be reasonably configured to ensure that the third blind detection object number is less than or equal to the channel monitoring budget corresponding to the second cell. For example, the network side device can configure the blind detection object number in the first control resource in N3 time units to be less than or equal to the channel monitoring budget corresponding to the second cell. Correspondingly, the terminal can not expect the third blind detection object number to be greater than the channel monitoring budget corresponding to the second cell, that is, the terminal expects the third blind detection object number to be less than or equal to the channel monitoring budget corresponding to the second cell.

[0160] For example, N3=1, the first control resource is all SS on the second cell, and on a certain time unit, the network side device ensures that after mapping all PDCCH candidates / CCEs of the SS on the second cell, the number of PDCCH candidates or CCEs that the terminal needs to monitor does not exceed the channel monitoring budget corresponding to the second cell.

[0161] Optionally, the M cells include the first cell and the second cell, and the channel monitoring budget corresponding to the second cell is the channel monitoring budget corresponding to the first cell.

[0162] In this embodiment, the channel monitoring budget corresponding to the second cell can be the channel monitoring budget corresponding to the first cell. For example, the Pcell is self-scheduled and is scheduled by the Scell, in the case of using the same SCS on the Pcell and the Scell, the channel monitoring budget corresponding to the Scell is the channel monitoring budget corresponding to the Pcell; or in the case of reusing the channel monitoring budget of the Pcell for the Scell, the channel monitoring budget corresponding to the Scell is the channel monitoring budget corresponding to the Pcell.

[0163] Optionally, the M cells include a third cell, and the channel monitoring budget corresponding to the third cell is a third channel monitoring budget determined according to at least one of the following:

[0164] The channel monitoring budget supported by the terminal;

[0165] The preconfigured channel monitoring budget;

[0166] The protocol pre-defined channel monitoring budget;

[0167] The channel monitoring budget configured by the network side device;

[0168] The fourth channel monitoring budget determined according to the second control resource;

[0169] determining a seventh channel monitoring budget according to at least one of at least one fifth channel monitoring budget and at least one sixth channel monitoring budget, wherein the fifth channel monitoring budget is a channel monitoring budget corresponding to a fourth cell, the fourth cell being a cell different from the third cell in the M cells, and the sixth channel monitoring budget is a joint channel monitoring budget between at least two cells in the M cells.

[0170] In the embodiment, the third cell can be the first cell, or a cell different from the first cell in the M cells.

[0171] The channel monitoring budget supported by the terminal can be, for example, a channel monitoring budget supported by the capability of the terminal. Alternatively, the terminal can report the channel monitoring budget supported by the terminal to the network side device to inform the network side device of the capability of the terminal.

[0172] For the preconfigured channel monitoring budget, the terminal can also report the configured channel monitoring budget to the network side device. For example, the preconfigured channel monitoring budget is taken as the capability of the terminal, and the terminal reports the preconfigured channel monitoring budget to the network side device to inform the network side device of the capability of the terminal.

[0173] For the channel monitoring budget configured by the network side device, the network side device can indicate the channel monitoring budget corresponding to the third cell to the terminal through signaling such as SIB, DCI, RRC or MAC CE.

[0174] The second control resource can include a control resource of the third cell, for example, an SS of the third cell.

[0175] For the seventh channel monitoring budget determined according to at least one of at least one fifth channel monitoring budget and at least one sixth channel monitoring budget, the following is described by way of example:

[0176] For example, the fifth channel monitoring budget is L5, the number of the sixth channel monitoring budget is L6, and the seventh channel monitoring budget is L7. L7 can be determined according to one of the following calculation formulas:

[0177] L7=(γ1*L6-β1*L5) / α1; wherein α1, β1 and γ1 are weight values;

[0178] L7=θ1*L6; wherein θ1 is a weight value;

[0179] L7=Δ1*L5; wherein Δ1 is a weight value;

[0180] wherein X1 and Y1 are positive integers;

[0181] wherein P1 and Q1 are both positive integers;

[0182] wherein X2 and Y2 are both positive integers;

[0183] wherein P2 and Q2 are both positive integers.

[0184] Optionally, the third channel monitoring budget is one of:

[0185] a channel monitoring budget supported by the terminal;

[0186] a preconfigured channel monitoring budget;

[0187] a channel monitoring budget predefined by the protocol;

[0188] a channel monitoring budget configured by the network side device;

[0189] the fourth channel monitoring budget;

[0190] the seventh channel monitoring budget;

[0191] a maximum, a minimum, an average or a weighted value of at least two of the channel monitoring budget supported by the terminal, the preconfigured channel monitoring budget, the channel monitoring budget predefined by the protocol, the channel monitoring budget configured by the network side device, the fourth channel monitoring budget and the seventh channel monitoring budget.

[0192] In this embodiment, the channel monitoring budget corresponding to the third cell, i.e., the third channel monitoring budget, can be the channel monitoring budget supported by the terminal, or can be the preconfigured channel monitoring budget, or can be the channel monitoring budget predefined by the protocol, or can be the channel monitoring budget configured by the network side device, or can be the fourth channel monitoring budget, i.e., the channel monitoring budget determined according to the second control resource, or can be the seventh channel monitoring budget, i.e., the channel monitoring budget determined according to at least one of the at least one fifth channel monitoring budget and the at least one sixth channel monitoring budget, or the channel monitoring budget calculated according to at least two of the channel monitoring budgets obtained by the above six manners, for example, the channel monitoring budget supported by the terminal is La, and the channel monitoring budget configured by the network side device is Lb, and a larger value or a smaller value of La and Lb can be taken as the channel monitoring budget corresponding to the third cell.

[0193] Optionally, the fourth channel monitoring budget is a maximum, a minimum, an average or a weighted value of N4 fourth blind detection objects;

[0194] Each of the fourth blind detection object numbers is determined according to blind detection objects in at least one control resource of the second control resource in each of the N4 time units.

[0195] In the embodiment, the value of N4 can be preconfigured, pre-defined by a protocol, or configured by a network side device, etc. The time unit can include, but is not limited to, a slot, an occasion, a time span, etc. The N4 time units can be any N4 time units, or specific N4 time units.

[0196] The N4 fourth blind detection object numbers can be respectively determined according to blind detection objects in at least one control resource of the second control resource in the N4 time units. For example, the N4 fourth blind detection object numbers can be respectively the number of blind detection objects in one control resource of the second control resource that the terminal needs to monitor in the N4 time units, or the N4 fourth blind detection object numbers can be respectively weighted values of the number of blind detection objects in multiple control resources of the second control resource that the terminal needs to monitor in the N4 time units.

[0197] Optionally, each of the fourth blind detection object numbers is respectively the number of blind detection objects in a third sub-control resource of the second control resource that the terminal needs to perform the first operation in each of the N4 time units, and the third sub-control resource includes one control resource in the second control resource.

[0198] Or

[0199] Each of the fourth blind detection object numbers is respectively a weighted value of the number of blind detection objects in a fourth sub-control resource of the second control resource that the terminal needs to perform the first operation in each of the N4 time units, and the fourth sub-control resource includes at least two control resources in the second control resource.

[0200] In the embodiment, the third sub-control resource includes one control resource in the second control resource, for example, the third sub-control resource can include any one control resource in the second control resource, or the third sub-control resource can include one specific control resource in the second control resource. Optionally, the third sub-control resource can include one CSS in the second control resource, or one USS in the second control resource.

[0201] The fourth sub-control resource can include at least two control resources in the second control resource. For example, the fourth sub-control resource can include any number of control resources in the second control resource, or the fourth sub-control resource can include a specific number of control resources in the second control resource. Alternatively, the fourth sub-control resource can include at least one CSS and at least one USS in the second control resource, or include at least two CSSs in the second control resource.

[0202] In an embodiment, the N4 fourth blind detection object numbers can respectively be the number of blind detection objects of the third sub-control resource that the terminal needs to perform the first operation in the N4 time units. For example, if the N4 time units include time unit #1 and time unit #2, the N4 fourth blind detection object numbers can include the number of blind detection objects of the third sub-control resource that the terminal needs to monitor in time unit #1 and the number of blind detection objects of the third sub-control resource that the terminal needs to monitor in time unit #2.

[0203] For the number of blind detection objects of the third sub-control resource that the terminal needs to monitor in each time unit, for example, if the third sub-control resource is search space #X, the number of blind detection objects of the third sub-control resource that the terminal needs to monitor in each time unit is the number of blind detection objects in search space #X that the terminal needs to monitor in each time unit.

[0204] In another embodiment, the N4 fourth blind detection object numbers can respectively be the weighted values of the number of blind detection objects of the fourth sub-control resource that the terminal needs to perform the first operation in the N4 time units. For example, if the N4 time units include time unit #1 and time unit #2, the N4 fourth blind detection object numbers can include the weighted value of the number of blind detection objects of the fourth sub-control resource that the terminal needs to monitor in time unit #1 and the weighted value of the number of blind detection objects of the fourth sub-control resource that the terminal needs to monitor in time unit #2. It should be noted that the weighting coefficients in this embodiment can be reasonably set according to actual conditions, for example, the weighting coefficients are all 1.

[0205] For example, the fourth sub-control resource includes SS#1 and SS#2, SS#1 has 2 and 4 PDCCH candidates on slot#1 and slot#3 respectively, SS#2 has 3 PDCCH candidates on slot#1, then on slot#1 there are totally 5 (i.e. 2+3) PDCCH candidates to be monitored, i.e. the weighted value of the blind detection objects number in SS#1 and the blind detection objects number in SS#2 to be monitored by the terminal on slot#1 is 5, on slot#3 there are totally 4 PDCCH candidates to be monitored, i.e. the weighted value of the blind detection objects number in SS#1 and the blind detection objects number in SS#2 to be monitored by the terminal on slot#3 is 4 (i.e. 4+0). Alternatively, if the fourth channel monitoring budget is the maximum value of N4 fourth blind detection objects number, then in this embodiment since 5>4, the fourth channel monitoring budget = 5.

[0206] In this embodiment, the fourth channel monitoring budget described above can be the maximum value, the minimum value, the average value or the weighted value of the N4 fourth blind detection objects number, which will be illustrated by examples as follows.

[0207] Example one: the third sub-control resource includes SS#1, the number of PDCCH candidates in SS#1 on slot#1 is C1, the number of PDCCH candidates in SS#1 on slot#2 is D1, then the fourth channel monitoring budget can be the maximum value of C1 and D1, or the minimum value of C1 and D1, or the average value of C1 and D1, or the weighted value of C1 and D1.

[0208] Example two: the fourth sub-control resource includes SS#1 and SS#2, the weighted value of the PDCCH candidates in SS#1 and the PDCCH candidates in SS#2 on slot#1 is C2, the weighted value of the PDCCH candidates in SS#1 and the PDCCH candidates in SS#2 on slot#2 is D2, then the fourth channel monitoring budget can be the maximum value of C2 and D2, or the minimum value of C2 and D2, or the average value of C2 and D2, or the weighted value of C2 and D2.

[0209] Example 3: the fourth sub-control resource includes SS#1 and SS#2, SS#1 and SS#2 overlap in a certain slot, i.e., the above N time units are 1 slot, and the number of PDCCH candidates of SS#1 on the overlapping slot is 4, and the number of PDCCH candidates of SS#2 is 2, then the fourth channel monitoring budget can be 4+2=6. Alternatively, the above SS#1 and SS#2 can be SSs used for scheduling the first cell.

[0210] Example 4: the weighting coefficient is 1, the fourth sub-control resource includes SS#1 and SS#2, SS#1 and SS#2 overlap in 4 consecutive 30 kHz slots, and the 4 slots can correspond to 2 15 kHz slots, and the number of PDCCH candidates of SS#1 on the overlapping first 30 kHz slot is 4, and the number of PDCCH candidates of SS#2 is 4, the number of PDCCH candidates of SS#1 on the overlapping second 30 kHz slot is 2, and the number of PDCCH candidates of SS#2 is 2, the number of PDCCH candidates of SS#1 on the overlapping third 30 kHz slot is 4, and the number of PDCCH candidates of SS#2 is 4, the number of PDCCH candidates of SS#1 on the overlapping fourth 30 kHz slot is 6, and the number of PDCCH candidates of SS#2 is 6, N4 time units are 2 consecutive 30 kHz slots in the time range of 1 15 kHz slot, then the fourth channel monitoring budget can be determined according to the weighting value of the PDCCH candidate on the third slot (i.e., 4+4) and the weighting value of the PDCCH candidate on the fourth slot (i.e., 6+6), i.e., the fourth channel monitoring budget can be (4+4)+(6+6)=20. Alternatively, the above SS#1 and SS#2 can be SSs used for scheduling the first cell.

[0211] For example, the fourth sub-control resource includes SS#1 and SS#2, the PDCCH candidate number of SS#1 in the first slot of the 4 slots is 4, the PDCCH candidate number of SS#2 in the first slot of the 4 slots is 4, the PDCCH candidate number of SS#1 in the second slot of the 4 slots is 2, the PDCCH candidate number of SS#2 in the second slot of the 4 slots is 2, the PDCCH candidate number of SS#1 in the third slot of the 4 slots is 3, the PDCCH candidate number of SS#2 in the third slot of the 4 slots is 4, the PDCCH candidate number of SS#1 in the fourth slot of the 4 slots is 6, the PDCCH candidate number of SS#2 in the fourth slot of the 4 slots is 6, and the N4 time units are 2 slots of 30 kHz, wherein the 2 slots of 30 kHz can be continuous or discontinuous, the fourth channel monitoring budget can be determined according to the weighted value of the PDCCH candidate in the first slot (i.e., 4+4) and the weighted value of the PDCCH candidate in the fourth slot (i.e., 6+6), that is, the fourth channel monitoring budget can be (4+4)+(6+6)=20. Alternatively, the above SS#1 and SS#2 can be SSs for scheduling the first cell.

[0212] Alternatively, the N4 time units are N4 time units corresponding to the first reference sub-carrier bandwidth.

[0221] In the embodiment, the M cells include the first cell, that is, the first cell supports self-scheduling.

[0222] Taking the first cell as Cell#1 and the second cell as Cell#2, the first reference subcarrier bandwidth can be Cell#1 SCS, or the first reference subcarrier bandwidth can be Cell#2 SCS, or the first reference subcarrier bandwidth can be max(Cell#1 SCS, Cell#2 SCS), or the first reference subcarrier bandwidth can be min(Cell#1 SCS, Cell#2 SCS), or the first reference subcarrier bandwidth can be a preconfigured SCS, or the first reference subcarrier bandwidth can be a protocol predefined SCS, or the first reference subcarrier bandwidth can be a SCS configured by a network side device.

[0223] Optionally, the third cell is the first cell, the fourth channel monitoring budget is a maximum of the N4 fourth blind detection object numbers, and the second control resource includes all CSS of the first cell.

[0224] In this embodiment, when the channel monitoring budget of the first cell is a maximum of N4 fourth blind detection object numbers, the second control resource can include all CSS of the first cell.

[0227] at least one control resource dedicated to self-scheduling on the first cell;

[0228] at least one common control resource of the first cell;

[0229] at least one dedicated control resource of the first cell.

[0230] For example, the control resource of this embodiment can include an SS, the common control resource of this embodiment can include a CSS, and the dedicated control resource of this embodiment can include a USS.

[0231] The at least one control resource available for self-scheduling on the first cell may, for example, be any SS or a specific SS or all SS available for self-scheduling on the first cell.

[0232] The at least one control resource dedicated to self-scheduling on the first cell may, for example, be any SS or a specific SS or all SS dedicated to self-scheduling on the first cell.

[0233] The at least one common control resource of the first cell may be, for example, any CSS, a specific CSS, or all CSSs on the first cell.

[0234] The at least one dedicated control resource of the first cell may be, for example, any USS, a specific USS, or all USSs on the first cell.

[0235] Optionally, the M cells do not include the first cell, and the first reference subcarrier bandwidth is one of:

Further, one preferred embodiment is that L1 is the maximum number of blind detection objects corresponding to one or more CSS on the first cell in one time unit, or the maximum value of the sum of the blind detection objects corresponding to one or more CSS on the first cell in one time unit.

[0451] Another optional embodiment where the number of PDCCH candidates or CCEs in the first control resource that may or actually needs to be monitored within a specific or arbitrary N1 time units does not exceed L1 is: the first control resource is the CSS on cell #1, that is, the number of PDCCH candidates or CCEs in the CSS that may or actually needs to be monitored within a specific or arbitrary N1 time units on cell #1 does not exceed L1. Further, a preferred embodiment is that L1 is the maximum number of blind detection objects corresponding to one or more CSSs on the first cell in a time unit, or the maximum value of the sum of blind detection objects corresponding to one or more CSSs on the first cell in a time unit.

[0452] It should be noted that the above time units can be slots, occasions, or spans. L1 can be the channel monitoring budget corresponding to cell#1 (i.e., the first cell), L2 is the channel monitoring budget corresponding to cell#2 (i.e., the second cell), and L3 is the joint channel monitoring budget between cell#1 and cell#2.

[0453] For example, such as Figure 7c As shown, L3 = 44, L2 = 20, then L1 = 44 - 20 = 24. Cell #1 has SS#1 and SS#2, and cell #2 has SS#3. SS#2 can be used by cell #2 to schedule cell #1. Therefore, an example where the number of first control resources that may or actually need to be monitored within a specific or arbitrary N1 time units does not exceed L1 is: N1 = 1, the time unit is a slot, the first control resource is a PDCCH candidate, and thus the number of PDCCH candidates that need to be monitored within any slot does not exceed 44.

[0454] For example, such as Figure 7d As shown, Figure 7d The numbers on each SS represent the number of PDCCH candidates in that SS within that slot. Therefore, in slot2, for the case of scheduling cell#1, the number of self-scheduled PDCCH candidates that need to be monitored on cell#1 is 16 + 16 = 32 > L1. Thus, the user discards, does not map, or does not monitor SS#2 in slot2.

[0455] Example 2: L2 under the same SCS

[0456] For example, such as Figure 7e As shown, cell #1 has SS #1 and SS #2, and cell #2 has SS #3. SS #2 can be used by cell #2 to schedule cell #1. The SCS of cell #1 and cell #2 are the same.Figure 8 The number on each SS in the slot is the number of PDCCH candidates in the SS in the slot. In slot 2, the number of PDCCH candidates that the terminal can need to monitor in SS#2 in cell#2 is 16.

[0457] Therefore, an optional embodiment of L2, which is the maximum number of blind detection objects in the third sub-control resource that the terminal can or actually needs to monitor in a certain or any N4 time units, is that N4 = 1, the time unit is a slot, the third sub-control resource is SS#2, the maximum number of blind detection objects is the maximum number of PDCCH candidates, and L2 = 16.

[0458] Example Three: L2 in Different SCS

[0459] For example, as shown in FIG. 1, the SS configuration on cell#1 is not assumed, there are SS#1 and SS#2 on cell#2, the SCS of cell#1 is 15 kHz, and the SCS of cell#2 is 30 kHz. Figure 8 The number on each SS in the slot is the number of PDCCH candidates in the SS in the slot. In slot 2, the number of PDCCH candidates that the terminal can need to monitor in SS#2 in cell#2 is 16. Figure 8 The number on each SS in the slot is the number of PDCCH candidates in the SS in the slot. In slot 2, the number of PDCCH candidates that the terminal can need to monitor in SS#2 in cell#2 is 16.

[0460] For example, as shown in FIG. 1, the SS configuration on cell#1 is not assumed, there are SS#1 and SS#2 on cell#2, the SCS of cell#1 is 15 kHz, and the SCS of cell#2 is 30 kHz. Figure 5As shown, no assumption is made for SS configuration on cell#1, there are SS#1 and SS#2 on cell#2, cell#1 SCS=15KHz, cell#2 SCS=30KHz. L2 is the maximum value of the weighted number of blind detection objects in the third sub-control resource that the terminal can or actually needs to monitor on a certain or any N4 time units. Another optional embodiment of L2 is: the weighting coefficient is 1, SS#1 and SS#2 overlap in certain 4 30kHz slots, and on the first overlapping slot, the PDCCH candidate of SS#1 is 4, the PDCCH candidate of SS#2 is 4, on the second overlapping slot, the PDCCH candidate of SS#1 is 2, the PDCCH candidate of SS#2 is 2, on the third overlapping slot, the PDCCH candidate of SS#1 is 2, the PDCCH candidate of SS#2 is 4, on the fourth overlapping slot, the PDCCH candidate of SS#1 is 6, the PDCCH candidate of SS#2 is 6, and N4 time units are 2 30kHz slots, then L2 is determined according to slot#0 slot#3, that is, L2=4+4+6+6=20; further, SS#1 and SS#2 are SSs that can be used to schedule cell#1.

[0461] Example four: L1 is the maximum PDCCH candidate number of cell#1 CSS on one slot

[0462] For example, there are CSS#1 and CSS#2 on cell#1, and CSS#1 and CSS#2 overlap on slot#1 and slot#2, and do not overlap on other slots, and the PDCCH candidate number of CSS#1 on slot#1 and slot#2 is 2 and 4 respectively, the PDCCH candidate number of CSS#2 on slot#1 and slot#2 is 2 and 4 respectively, and the PDCCH candidate number of CSS#1 and CSS#2 on the non-overlapping part does not exceed 8, then L1=4+4=8.

[0463] Example five: L1 is the maximum PDCCH candidate number required by all SSs on cell#1 on one slot

[0464] For example, there are CSS#1 and USS#2 on cell#1, and CSS#1 and USS#2 overlap in slot#1 and slot#2, and the PDCCH candidate numbers of CSS#1 in slot#1 and slot#2 are 2 and 4 respectively, the PDCCH candidate numbers of USS#2 in slot#1 and slot#2 are 2 and 4 respectively, and the PDCCH candidate numbers of non-overlapping parts of CSS#1 and USS#2 do not exceed 8, then L1=4+4=8.
