The following description describes the New Radio (NR) system for illustrative purposes and uses NR terms in most of the following descriptions, but these technologies can also be applied in applications other than NR system applications, such as the sixth generation (6th It may be applied to a (next-generation, 6G) communication system.

[0021] FIG. 1 shows a block diagram of a wireless communication system to which an embodiment of the present application is applicable. The wireless communication system includes a terminal 11 and a network-side device 12. Here, the terminal 11 may also be referred to as a terminal device or a user equipment (UE). The terminal 11 may be a terminal-side device such as a mobile phone, a tablet personal computer, a laptop computer (or called a notebook computer), a personal digital assistant (PDA), a palm-top computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), a wearable device, or a vehicle user equipment (VUE), a pedestrian user equipment (PUE), etc. The wearable device may include a smart watch, a bracelet, earphones, glasses, etc. It should be noted that in the embodiments of the present application, the specific type of the terminal 11 is not limited. The network-side device 12 may be a base station or a core network.Here, the base station may be referred to as a Node B, an evolved Node B, an access point, a Base Transceiver Station (BTS), a radio base station, a radio transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a Transmitting Receiving Point (TRP), or other suitable terms in the art. As long as the same technical effects are achieved, the base station is not limited to specific technical terms. For the sake of explanation, only the base station in the NR system in the embodiments of this application is taken as an example, but the specific type of the base station is not limited.

[0022] For the convenience of understanding, the following describes the related content related to the embodiments of this application. Cell scheduling: The fifth-generation (5th-Generation, 5G) New Radio (NR) system supports the configuration of one or more component carriers (CCs) or cells for a user equipment (UE). When the UE is configured as a single-carrier mode or a self-scheduling mode under carrier aggregation (CA), each CC or cell can configure multiple control resource sets (CORESETs), and multiple search spaces (SSs) including a common search space (CSS) and a UE-specific search space (USS). The network can flexibly configure the number of blind detections for each search space set, and the CORESET and the search space set may be flexibly associated. The UE blindly detects the physical downlink control channel (PDCCH) by using various radio network temporary identities (RNTIs) based on the configured CORESET and SS, demodulates the downlink control information (DCI), and obtains the scheduling information of each cell. Each DCI schedules the data of one cell.

[0023] If the channel quality of some cells is insufficient or the channel blocking probability is high, the network configures cross-carrier scheduling for the UE. That is, by configuring the control channel to another cell with relatively good channel quality, such as the Primary Cell (PCell), data of other cells, such as the Secondary Cell (SCell), can be scheduled in the cross-carrier. The subcarrier spacing (SCS) of the scheduling cell may be the same as or different from that of the scheduled cell. The scheduling cell may be in self-scheduling mode. At this time, this cell schedules only itself. When cross-carrier scheduling is configured for the scheduling cell, one or more scheduled cells other than itself can be scheduled. The scheduled cell has no own PDCCH and can only be scheduled by one scheduling cell. In the Release 15 NR system, one cell can only be scheduled by one scheduling cell. That is, it can only be scheduled by itself or only by another cell, and the PCell can only be scheduled by the PCell itself.

[0024] To reduce the implementation complexity of the UE, the NR system defines the maximum processing capacity of the UE for PDCCH that blindly detects one CC or cell. This capacity includes two parts: the maximum number of PDCCH candidates blindly detected within one slot, and the estimated number of maximum channels required for the UE to perform blind detection, that is, the number of non-duplicate control channel elements (CCEs). The maximum processing capacity of the UE is related to the SCS of the CC or cell being blindly detected. That is, the processing capacity within the next slot for different SCSs is different, as shown in Tables 1 to 3 for example. Note that the UE can also report the maximum blind detection capacity it supports during CA.

[0025] Note that to reduce the implementation complexity of the UE, the NR system defines the DCI size budget of the UE. That is, for each of the scheduled cells, it is specified that the number of different-sized DCI formats that the UE monitors the most is 4, and the maximum number of different-sized DCI formats in the USS is 3.

[0028] [Table 3] Maximum number of non-duplicate CCEs per slot for different SCS configurations in a single cell JPEG0007700258000003.jpg59152

[0029] It should be noted that, as shown in Figure 2, generally, the PCell is deployed on a carrier in a low-frequency band in order to consider expanding the coverage of the control channel. The bandwidth of the carrier in the low-frequency band is insufficient, and a large number of them have already been deployed in other series, such as Long Term Evolution (LTE). At this time, as shown in Figure 3, by scheduling the PCell with the SCell, it is necessary to solve the problem that the capacity of the PCell control channel is limited and to reduce the overhead of the control channel PDCCH. However, the Release 15 NR system does not support scheduling the PCell using the SCell, and when monitoring the PDCCH from two scheduling cells simultaneously, the complexity and power consumption of UE demodulation and realization are greatly improved, the hardware cost of the UE increases, which is not advantageous for the realization of the UE.

[0030] Overbooking: When multiple Search Space Sets (SS sets) are configured, since the monitoring spaces of different SS sets are configured independently, the number of PDCCH candidates / CCEs changes at different times. Therefore, it is allowed that the base station (BS) configures the total number of PDCCH candidates / CCEs in each slot to exceed the user's capabilities, which is called Overbooking.

[0031] Based on the configuration, in each slot, map the SS set according to the following rules: (1) Map the CSS set preferentially, that is, allocate the blind detection resources preferentially. (2) Map the USS, that is, allocate the blind detection resources for the USS, map or allocate in ascending order of the SS set ID, and do not map or allocate the SS set when the number of PDCCH candidates / CCEs exceeds the limit of the user's processing capabilities.

[0032] In the case where there is no overbooking function, the configuration of the SS set is restricted by the worst case. That is, after mapping the SS set in each slot, it is necessary to ensure that the total number of PDCCH candidates / CCEs does not exceed the user's capabilities. Therefore, the BS cannot fully utilize the user's blind detection ability and causes blocking of multiple users.

[0033] For example, as shown in FIG. 4, taking the mapping of CCEs by CSS, USS#1, and USS#2 as an example, the monitoring time configuration of CSS, USS#1, and USS#2 is shown in FIG. 4. For slot1, slot5, and slot9, after mapping CSS and USS#1, USS#2 cannot be further mapped, exceeding the user's capabilities.

[0034] Hereinafter, the control channel monitoring method according to the embodiments of the present application will be described in detail with reference to several embodiments and their application scenarios.

[0035] FIG. 5 is a flowchart of the control channel monitoring method according to the embodiments of the present application. This method may be executed by a terminal. As shown in FIG. 5, it includes the following steps.

[0036] In step 501, the terminal obtains a first channel monitoring budget. Here, the first cell supports being scheduled by M cells, where M is an integer greater than 1. The M cells include the first cell, and the first channel monitoring budget includes at least one of the channel monitoring budgets corresponding to at least one of the M cells and the joint channel monitoring budgets between at least two of the M cells. Alternatively, the M cells do not include the first cell, and the first channel monitoring budget includes at least one of the channel monitoring budget corresponding to the first cell, the channel monitoring budgets corresponding to at least one of the M cells, and the joint channel monitoring budgets between at least two of the M cells.

[0037] In this embodiment, the above channel monitoring budget may be referred to as the number of channel monitorings, may be referred to as the channel blind detection budget, or may be understood as the upper limit value (i.e., the maximum value) or the lower limit value (i.e., the minimum value) of the number of blind detection targets. Here, the above blind detection targets may include, but are not limited to, at least one of PDCCH candidate, CCE, DCI format, search space, monitoring occasion, time span (Span), and CORESET.

[0038] It should be noted that when the blind detection target includes at least two of PDCCH candidate, CCE and DCI format, search space, monitoring occasion, span, and CORESET, etc., the channel monitoring budget may include thresholds corresponding to each of the at least two. For example, when the blind detection target includes PDCCH candidate and CCE, the channel monitoring budget may include a threshold for the number of PDCCH candidates and a threshold for the number of CCEs. Here, the threshold may include an upper limit value or a lower limit value.

[0039] In one embodiment, the M cells may include a first cell. That is, the first cell may be self-scheduled or scheduled by other cells. For example, the primary cell may be self-scheduled or scheduled by the secondary cell. In this embodiment, the first channel monitoring budget may include at least one of a channel monitoring budget corresponding to at least one of the M cells and a joint channel monitoring budget between at least two of the M cells. Optionally, the first channel monitoring budget may at least include a channel monitoring budget corresponding to the first cell. It should be noted that all of the M cells may be the serving cells of the terminal.

[0040] In another embodiment, the above M cells do not include the first cell. That is, the first cell cannot be self-scheduled and can only be scheduled by a plurality of other cells. In this embodiment, the first channel monitoring budget may include at least one of the channel monitoring budget corresponding to the first cell, the channel monitoring budget corresponding to at least one of the M cells, and the joint channel monitoring budget between at least two of the M cells. Optionally, the above first channel monitoring budget includes at least the channel monitoring budget corresponding to the first cell. It should be noted that the above first cell and the M cells may both be serving cells of the terminal.

[0041] Here, the channel monitoring budget L1 corresponding to the first cell is The channel monitoring budget corresponding to the self-scheduling of the first cell or when the first cell is self-scheduled. For example, the first cell is a Pcell, and L1 is the channel monitoring budget for the Pcell to self-schedule, and The channel monitoring budget corresponding to the cell when the first cell is scheduled. For example, L1 is the channel monitoring budget corresponding to the cell when the first cell is the cell for its own self-scheduling, and It may include at least one of the channel monitoring budgets corresponding to the search spaces in the first cell.

[0042] Optionally, the search space in the above first cell may include one of the CSS and / or USS in the first cell, the specific search space in the first cell, and the CSS and / or USS used for self-scheduling in the first cell.

[0043] The second cell may be any cell other than the first cell among the M cells, and the channel monitoring budget L2 corresponding to the second cell is a channel monitoring budget corresponding to the first cell being scheduled by the second cell. For example, the first cell is a Pcell, and L2 is a channel monitoring budget corresponding to the Pcell being scheduled by an Scell. a channel monitoring budget corresponding to the second cell scheduling the first cell, a channel monitoring budget corresponding to the search space in the second cell, and a channel monitoring budget corresponding to the search space that can be used for the first cell scheduling in the second cell. For example, the first cell is a Pcell, and when USS#X and USS#Y in Scell#1 can be used for the scheduling of the Pcell, L2 may include at least one of a channel monitoring budget corresponding to USS#X and a channel monitoring budget corresponding to USS#Y.

[0044] The above joint channel monitoring budget may be understood as the total channel monitoring budget. The joint channel monitoring budget between at least two cells among the M cells may include at least one joint channel monitoring budget. For example, the M cells include Cell#1, Cell#2, and Cell#3, and the joint channel monitoring budget between at least two cells among the M cells may include at least one of the joint channel monitoring budget between Cell#1 and Cell#2, the joint channel monitoring budget between Cell#2 and Cell#3, the joint channel monitoring budget between Cell#1 and Cell#3, and the joint channel monitoring budget between Cell#1, Cell#2, and Cell#3.

[0045] It should be noted that the joint channel monitoring budget between the at least two cells may be referred to as the joint channel monitoring budget corresponding to any one of the at least two cells. For example, the joint channel monitoring budget between Cell#1 and Cell#2 may be referred to as the joint channel monitoring budget corresponding to Cell#1, or may be referred to as the joint channel monitoring budget corresponding to Cell#2. When the number of joint channel monitoring budgets is 1, the joint channel monitoring budget between the at least two cells may be directly referred to as the joint channel monitoring budget.

[0046] Optionally, the joint channel monitoring budget corresponding to the first cell may be the channel monitoring budget corresponding to the first cell, or the joint channel monitoring budget corresponding to the first cell may be the channel monitoring budget corresponding when the first cell is the cell being scheduled. For example, the joint channel monitoring budget corresponding to the first cell may be the channel monitoring budget corresponding when the first cell is the cell being scheduled for the first cell and the first cell is the cell being scheduled for the second cell.

[0047] In step 502, the terminal performs a first operation on at least some of the first control resources based on the second channel monitoring budget. Here, the second channel monitoring budget includes at least one of the first channel monitoring budgets, and the first operation includes at least one of an operation of allocation and an operation of monitoring.

[0048] In this embodiment, the second channel monitoring budget includes at least one channel monitoring budget among the first channel monitoring budgets. For example, the first channel monitoring budget includes a channel monitoring budget L1 corresponding to a first cell, a channel monitoring budget L2 corresponding to a second cell, and a joint channel monitoring budget L3 between the first cell and the second cell, and the second channel monitoring budget includes L1.

[0049] The first control resource may include, but is not limited to, at least one of a search space, a monitoring occasion, a time span, a CORESET, a CCE, a PDCCH candidate, and a DCI format. For example, the first control resource includes at least one CSS in the first cell, or includes at least one USS in the first cell, or includes all SSs in the second cell, or includes an SS used for scheduling the first cell in the second cell, etc.

[0050] In one embodiment, the terminal may allocate at least some of the control resources among the first control resources based on the second channel monitoring budget. It should be noted that allocating at least some of the control resources among the first control resources may also be referred to as mapping at least some of the control resources among the first control resources.

[0051] In another embodiment, the terminal may monitor at least some of the control resources among the first control resources based on the second channel monitoring budget. It should be noted that monitoring at least some of the control resources among the first control resources may also be referred to as blindly detecting at least some of the control resources among the first control resources.

[0052] In another embodiment, the terminal may allocate and monitor at least some of the first control resources based on a second channel monitoring budget.

[0053] In the control channel monitoring method according to the embodiments of the present application, when the first cell is supported to be scheduled by a plurality of cells, the terminal can perform at least one of allocation and monitoring on at least some of the first control resources based on at least one channel monitoring budget among the first channel monitoring budgets, which can alleviate the scheduling blocking problem in the scheduling cell of the first cell and reduce the complexity of demodulation by the terminal when the first cell is scheduled by a plurality of cells.

[0054] Optionally, the M cells include the first cell, and the second channel monitoring budget includes a channel monitoring budget corresponding to the first cell.

[0055] In this embodiment, the first cell supports self-scheduling, and the terminal can allocate and / or monitor at least some of the first control resources based on the channel monitoring budget corresponding to the first cell.

[0056] Optionally, the first control resource may include the control resource of the first cell, the control resource that can be used for the self-scheduling of the first cell, the control resource dedicated to the self-scheduling of the first cell, or a specific control resource in the first cell.

[0057] In this embodiment, the control resource of the first cell is, for example, the SS in the first cell.

[0058] The control resources that can be used for the self-scheduling of the first cell may include at least one of the control resources that can be used for the self-scheduling of the first cell in the first cell and the control resources that can be used for the self-scheduling of the first cell in cells other than the first cell among the M cells. For example, it is a USS that can be used for the self-scheduling of the first cell in the first cell.

[0059] The control resources dedicated to the self-scheduling of the first cell may include at least one of the control resources dedicated to the self-scheduling of the first cell in the first cell and the control resources dedicated to the self-scheduling of the first cell in cells other than the first cell among the M cells. For example, it is the SS dedicated to the self-scheduling of the first cell in the first cell and the SS dedicated to the self-scheduling of the first cell in cells other than the first cell among the M cells.

[0060] The specific control resources in the first cell are, for example, specific SS in the first cell. It should be noted that the specific control resources in the first cell may be predefined by the protocol or may be indicated by network-side devices.

[0061] Optionally, the first control resource is at least one CSS in the first cell, and at least one USS in the first cell, and at least one CSS and at least one USS in the first cell, and one of the specific SS in the first cell.

[0062] Optionally, the number of first blind detection targets is not more than the channel monitoring budget corresponding to the first cell, and the number of first blind detection targets is the number of blind detection targets within the first control resource that the terminal needs to execute the first operation within N1 time units, where N1 is a positive integer.

[0063] In this embodiment, the above blind detection target may include, but is not limited to, at least one of a search space, a monitoring occasion, a time span, a CORESET, a PDCCH candidate, a CCE, and a DCI format. The value of N1 may be pre-configured, predefined by a protocol, or configured by a network-side device. The above time unit may include, but is not limited to, a slot, a monitoring occasion, or a time span. The above N1 time units may be any N1 time units or specific N1 time units.

[0064] The number of first blind detection targets may be the number of blind detection targets within the first control resource that the terminal needs to allocate within N1 time units, or the number of blind detection targets within the first control resource that the terminal needs to monitor within N1 time units, or the number of blind detection targets within the first control resource that the terminal needs to allocate and monitor within N1 time units.

[0065] Exemplarily, the number of PDCCH candidates or CCEs within the first control resource that the terminal needs to monitor within N1 time units is not more than the channel monitoring budget corresponding to the first cell.

[0066] Optionally, the network-side device may ensure that the number of first blind detection targets is not more than the channel monitoring budget corresponding to the first cell by reasonable configuration. For example, the network-side device may be configured such that the number of blind detection targets in the first control resource within N1 time units is not more than the channel monitoring budget corresponding to the first cell. Accordingly, the terminal may not expect that the number of first blind detection targets is greater than the channel monitoring budget corresponding to the first cell. That is, the terminal may expect that the number of first blind detection targets is not more than the channel monitoring budget corresponding to the first cell.

[0067] Optionally, when the number of second blind detection targets is greater than the channel monitoring budget corresponding to the first cell, the terminal may discard at least a part of the blind detection targets of at least a part of the first control resources, and / or perform at least one of the first operations on at least a part of the blind detection targets of at least a part of the first control resources. Here, the number of second blind detection targets is the number of blind detection targets in the first control resources that the terminal needs to perform the first operation within N2 time units, and N2 is a positive integer.

[0068] In this embodiment, the blind detection targets may include, but are not limited to, at least one of PDCCH candidate, CCE, and DCI. The value of N2 may be pre-configured, predefined by a protocol, or configured by a network-side device. The time unit may include, but is not limited to, a slot, an occasion, or a time span. The N2 time units may be any N2 time units or specific N2 time units.

[0069] The above-mentioned first number of blind detection targets may be the number of blind detection targets in the first control resource that the terminal needs to allocate within N2 time units, or the above-mentioned first number of blind detection targets may be the number of blind detection targets in the first control resource that the terminal needs to monitor within N2 time units, or the above-mentioned first number of blind detection targets may be the number of blind detection targets in the first control resource that the terminal needs to allocate and monitor within N2 time units.

[0070] Discarding at least some of the blind detection targets of at least some of the control resources in the first control resource may, for example, directly discard some of the control resources in the first control resource and also discard all the blind detection targets of the corresponding part of the control resources, or it may be to discard some of the blind detection targets of at least some of the control resources in the first control resource.

[0071] For example, in a certain time unit, after allocating the PDCCH candidate / CCE of SS#X, if the number of PDCCH candidates / CCEs that the terminal needs to monitor exceeds L1, then do not allocate the PDCCH candidate / CCE of SS#X, or do not allocate some of the PDCCH candidates / CCEs that exceed L1 in SS#X. Here, L1 is the channel monitoring budget corresponding to the first cell.

[0072] It should be noted that discarding at least some of the blind detection targets of at least some of the control resources in the first control resource may also be referred to as not monitoring or not mapping at least some of the blind detection targets of at least some of the control resources in the first control resource.

[0073] Performing the first operation on at least a part of the blind detection targets of at least a part of the first control resources may be, for example, performing the first operation only on the blind detection targets of a part of the control resources among the first control resources.

[0074] For example, in a certain time unit, after allocating the PDCCH candidates / CCEs of SS#X and SS#Y, if the number of PDCCH candidates / CCEs that the terminal needs to monitor exceeds the channel monitoring budget L1 corresponding to the first cell, but does not exceed L1 when only allocating the PDCCH candidates / CCEs of SS#X, then only allocate SS#X.

[0075] Optionally, N1 and N2 may be equal.

[0076] Optionally, discarding at least a part of the blind detection targets of at least a part of the control resources among the first control resources is discarding at least a part of the blind detection targets of at least one USS of the first control resources, discarding at least a part of the blind detection targets of a specific control resource of the first control resources, After mapping the blind detection targets within the first sub-control resources according to a first preset rule, if the number of blind detection targets that the terminal needs to monitor is greater than the channel monitoring budget corresponding to the first cell, then discarding at least a part of the blind detection targets of at least a part of the first sub-control resources including at least a part of the first control resources.

[0077] In this embodiment, the specific control resource may be a specific USS.

[0078] The above-mentioned first preset rule may be reasonably set according to the actual demand. For example, the above-mentioned first preset rule may be to map the blind detection targets in the control resource in ascending order of the index of the control resource (for example, the index of the search space).

[0079] After mapping the blind detection targets in the first sub-control resource according to the first preset rule, if the number of blind detection targets that the terminal needs to monitor is greater than the channel monitoring budget corresponding to the first cell, at least some of the blind detection targets in the first sub-control resource are discarded. For example, all the blind detection targets in the first sub-control resource may be discarded, or only some of the blind detection targets that exceed the channel monitoring budget corresponding to the first cell in the first sub-control resource may be discarded.

[0080] Optionally, performing the first operation on at least some of the blind detection targets of at least some of the control resources in the first control resource is performing the first operation on at least some of the blind detection targets of at least one CSS in the first control resource, After mapping the blind detection targets in the second sub-control resource according to the second preset rule, if the number of blind detection targets that the terminal needs to monitor is less than or equal to the channel monitoring budget corresponding to the first cell, it may include one of performing the first operation on at least some of the blind detection targets of at least some of the control resources including at least some of the first control resources in the second sub-control resource.

[0081] In this embodiment, the second preset rule may be reasonably set according to the actual demand. For example, the second preset rule may be to map the blind detection targets in the control resource in ascending order of the index of the control resource (for example, the index of the search space).

[0082] For example, at least a part of the blind detection targets of at least one CSS of the first control resource may be allocated or monitored, or at least a part of the blind detection targets of the second sub-control resource may be allocated or monitored.

[0083] Optionally, the second channel monitoring budget includes the channel monitoring budget corresponding to the second cell, and the second cell is a cell different from the first cell among the M cells.

[0084] In this embodiment, the M cells include the first cell. That is, when the first cell supports self-scheduling, the second cell may be any cell different from the first cell among the M cells. When the M cells do not include the first cell, that is, when the first cell does not support self-scheduling, the second cell may be any cell among the M cells. Specifically, the terminal may allocate and / or monitor at least a part of the control resources among the first control resources based on the channel monitoring budget corresponding to the second cell that schedules the first cell.

[0085] Optionally, the second cell is a cell different from the first cell among the M cells, and the first control resource includes the control resource of the second cell, the control resource that can be used for scheduling the first cell by the second cell, and the control resource dedicated to scheduling the first cell by the second cell. It includes any one of the specific control resources in the second cell.

[0086] In this embodiment, the control resources of the second cell may be understood as any control resources of the second cell, for example, some or all of the SSs in the second cell.

[0087] The control resources that can be used for scheduling the first cell by the second cell may include at least one of the control resources that can be used for scheduling the first cell by the second cell in the second cell and the control resources that can be used for scheduling the first cell by the second cell in cells other than the second cell among the M cells. Exemplarily, the control resources that can be used for scheduling the first cell by the second cell may be the SSs of the control resources that can be used for scheduling the first cell by the second cell.

[0088] The control resources dedicated to scheduling the first cell by the second cell may include at least one of the control resources dedicated to scheduling the first cell by the second cell in the second cell and the control resources dedicated to scheduling the first cell by the second cell in cells other than the second cell among the M cells. Exemplarily, the control resources dedicated to scheduling the first cell by the second cell may be the SSs dedicated to scheduling the first cell by the second cell.

[0089] The specific control resource in the second cell above is, for example, a specific SS in the second cell. It should be noted that the specific control resource in the second cell above may be predefined by the protocol or may be indicated by the network-side device.

[0090] Optionally, the number of third blind detection targets is not more than the channel monitoring budget corresponding to the second cell, and the number of third blind detection targets is the number of blind detection targets within the first control resource that the terminal needs to execute the first operation within N3 time units. The second cell is a cell different from the first cell among the M cells, and N3 is a positive integer.

[0091] In this embodiment, the above blind detection target may include, but is not limited to, at least one of PDCCH candidate, CCE, DCI, etc. The value of N3 may be pre-configured, predefined by a protocol, or configured by network-side equipment. The above time unit may include, but is not limited to, a slot, an occasion, or a time span. The N3 time units may be any N3 time units or specific N3 time units.

[0092] The number of third blind detection targets may be the number of blind detection targets within the first control resource that the terminal needs to allocate within N3 time units, or the number of blind detection targets within the first control resource that the terminal needs to monitor within N3 time units, or the number of blind detection targets within the first control resource that the terminal needs to allocate and monitor within N3 time units.

[0093] Exemplarily, the number of PDCCH candidates or CCEs within the first control resource that the terminal needs to monitor within N3 time units is not more than the channel monitoring budget corresponding to the second cell.

[0094] Optionally, the network-side device may ensure that the number of third blind detection targets is below the channel monitoring budget corresponding to the second cell by reasonably setting. For example, the network-side device may be configured such that the number of blind detection targets within the first control resource is below the channel monitoring budget corresponding to the second cell within N3 time units. Accordingly, the terminal may not need to expect that the number of third blind detection targets is greater than the channel monitoring budget corresponding to the second cell. That is, the terminal may expect that the number of third blind detection targets is below the channel monitoring budget corresponding to the second cell.

[0095] For example, N3 = 1, the first control resource is all the SSs in the second cell, and within a certain time unit, after the network-side device maps all the PDCCH candidates / CCEs of the SSs in the second cell, it ensures that 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.

[0096] 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.

[0097] In this embodiment, the channel monitoring budget corresponding to the second cell may be the channel monitoring budget corresponding to the first cell. For example, when the Pcell is scheduled by itself and by the Scell, and the Pcell and the Scell use the same SCS, the channel monitoring budget corresponding to the Scell is the channel monitoring budget corresponding to the Pcell, or when the channel monitoring budget of the Pcell is reused in the Scell, the channel monitoring budget corresponding to the Scell is the channel monitoring budget corresponding to the Pcell.

[0098] Optionally, the M cells include a third cell, and the channel monitoring budget corresponding to the third cell is the channel monitoring budget supported by the terminal, a pre-configured channel monitoring budget, a channel monitoring budget predefined by a protocol, a channel monitoring budget configured by a network-side device, a fourth channel monitoring budget determined based on a second control resource, or a seventh channel monitoring budget determined based on at least one of at least one fifth channel monitoring budget and at least one sixth channel monitoring budget, where the fifth channel monitoring budget is a channel monitoring budget corresponding to a fourth cell, the fourth cell is a cell different from the third cell among the M cells, the sixth channel monitoring budget is a joint channel monitoring budget between at least two cells among the M cells, and the third channel monitoring budget is determined based on at least one of the seventh channel monitoring budget.

[0099] In this embodiment, the third cell may be the first cell or a cell different from the first cell among the M cells.

[0100] The channel monitoring budget supported by the terminal may be, for example, a channel monitoring budget supported by the capabilities of the terminal. Optionally, the terminal may report the channel monitoring budget it supports to the network-side device to inform the network-side device of the capabilities of this terminal.

[0101] For a pre-configured channel monitoring budget, optionally, the terminal may report this pre-configured channel monitoring budget to the network-side device. For example, taking the pre-configured channel monitoring budget as the capability of the terminal, the terminal may report the pre-configured channel monitoring budget to the network-side device to inform the network-side device of the terminal's capability.

[0102] For the channel monitoring budget configured by the network-side device, for example, the network-side device may instruct the terminal to the channel monitoring budget corresponding to the third cell by means of signaling such as SIB, DCI, RRC, or MAC CE.

[0103] The second control resource may include the control resource of the third cell, for example, the SS of the third cell.

[0104] For the seventh channel monitoring budget determined based on at least one of the at least one fifth channel monitoring budget and the at least one sixth channel monitoring budget, examples will be described together below. For example, if the fifth channel monitoring budget is L5, the number of the sixth channel monitoring budgets is L6, and the seventh channel monitoring budget is L7, L7 may be determined based on one of the following calculation formulas. L7 = (γ1 * L6 - β1 * L5) / α1, where α1, β1, and γ1 are weight values. L7 = θ1 * L6, where θ1 is a weight value. L7 = Δ1 * L5, where Δ1 is a weight value. X1 / L7 + Y1 / L5 = 1, where both X1 and Y1 are positive integers. L7 / P1 + L5 / Q1 = 1, where both P1 and Q1 are positive integers. X2 / L7 + Y2 / L6 = 1, where both X2 and Y2 are positive integers. L7 / P2 + L6 / Q2 = 1, where both P2 and Q2 are positive integers.

[0105] Optionally, the third channel monitoring budget is the channel monitoring budget supported by the terminal, the pre-configured 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, the seventh channel monitoring budget, one of the maximum value, minimum value, average value, or weighted value of at least two of the channel monitoring budget supported by the terminal, the pre-configured 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.

[0106] In this embodiment, the channel monitoring budget corresponding to the third cell, i.e., the third channel monitoring budget, may be the channel monitoring budget supported by the terminal, or a pre-configured channel monitoring budget, or a channel monitoring budget predefined by a protocol, or a channel monitoring budget configured by a network-side device, or the fourth channel monitoring budget, i.e., the channel monitoring budget determined based on the second control resource, or the seventh channel monitoring budget, i.e., the channel monitoring budget determined based on at least one of at least one fifth channel monitoring budget and at least one sixth channel monitoring budget, or a channel monitoring budget obtained by calculation based on at least two of the channel monitoring budgets obtained by the above six methods. 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. The relatively larger value or the relatively smaller value of La and Lb may be used as the channel monitoring budget corresponding to the third cell.

[0107] Optionally, the fourth channel monitoring budget is the maximum value, minimum value, average value or weighted value of N4 fourth blind detection target numbers. Here, each of the fourth blind detection target numbers is determined based on at least one control resource within the second control resource in each of the N4 time units.

[0108] In this embodiment, the value of N4 may be pre-configured, pre-defined by a protocol, or configured by a network-side device, etc. The time unit may include, but is not limited to, a slot, an occasion, or a time span. The N4 time units may be any N4 time units or specific N4 time units.

[0109] The N4 fourth blind detection target numbers may be determined based on the blind detection targets within at least one control resource of the second control resource in each of the N4 time units. For example, the N4 fourth blind detection target numbers may be the number of blind detection targets within one control resource of the second control resource that the terminal needs to monitor for N4 time units, or the weighted values of the number of blind detection targets within a plurality of control resources of the second control resource that the terminal needs to monitor for N4 time units.

[0110] Optionally, each of the fourth blind detection target numbers is the number of blind detection targets within a third sub-control resource that the terminal needs to execute the first operation in each of the N4 time units, and the third sub-control resource includes one control resource within the second control resource. Or Each of the fourth blind detection target numbers is the weighted value of the number of blind detection targets within a fourth sub-control resource that the terminal needs to execute the first operation in each of the N4 time units, and the fourth sub-control resource includes at least two control resources within the second control resource.

[0111] In this embodiment, the third sub-control resource includes one control resource within the second control resource. For example, the third sub-control resource may include any one control resource within the second control resource, or the third sub-control resource may include one specific control resource within the second control resource. Optionally, the third sub-control resource may include one CSS within the second control resource, or may include one USS within the second control resource.

[0112] The fourth sub-control resource may include at least two control resources within the second control resource. For example, the fourth sub-control resource may include any plurality of control resources within the second control resource, or the fourth sub-control resource may include a specific plurality of control resources within the second control resource. Optionally, the fourth sub-control resource may include at least one CSS and at least one USS within the second control resource, or may include at least two CSSs within the second control resource.

[0113] In one embodiment, the N4 numbers of the fourth blind detection targets may each be the number of blind detection targets within the third sub-control resource that the terminal needs to execute the first operation in N4 time units. For example, if the N4 time units include time unit #1 and time unit #2, the N4 numbers of the fourth blind detection targets may include the number of blind detection targets of the third sub-control resource that the terminal needs to monitor in time unit #1 and the number of blind detection targets of the third sub-control resource that the terminal needs to monitor in time unit #2.

[0114] For the number of blind detection targets of the third sub-control resource that the terminal needs to monitor in each time unit, for example, when the third sub-control resource is search space #X, the number of blind detection targets of the third sub-control resource that the terminal needs to monitor in each time unit is the number of blind detection targets within search space #X that the terminal needs to monitor in each time unit.

[0115] In another embodiment, the above N4 numbers of fourth blind detection targets are respectively the weighted values of the number of blind detection targets within the fourth sub-control resource that the terminal needs to perform the first operation in N4 time units. For example, if the N4 time units include time unit #1 and time unit #2, the above N4 numbers of fourth blind detection targets may include the weighted value of the number of blind detection targets 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 targets of the fourth sub-control resource that the terminal needs to monitor in time unit #2. It should be noted that in this embodiment, the weighting coefficient may be reasonably set according to the actual situation. For example, the weighting coefficients are all 1.

[0116] For example, if the fourth sub-control resource includes SS#1 and SS#2, SS#1 has 2 and 4 PDCCH candidates in slot#1 and slot#3 respectively, and SS#2 has 3 PDCCH candidates in slot#1, then a total of 5 (i.e., 2 + 3) PDCCH candidates need to be monitored in slot#1. That is, the weighted value of the number of blind detection targets in SS#1 and the number of blind detection targets in SS#2 that the terminal needs to monitor in slot#1 is 5. In slot#3, a total of 4 PDCCH candidates need to be monitored. That is, the weighted value of the number of blind detection targets in SS#1 and the number of blind detection targets in SS#2 that the terminal needs to monitor in slot#3 is 4 (i.e., 4 + 0). Optionally, when the fourth channel monitoring budget is the maximum value of the N4 fourth blind detection target numbers, in this embodiment, since 5 > 4, the fourth channel monitoring budget is 5.

[0117] In this embodiment, the fourth channel monitoring budget may be the maximum value, or the minimum value, or the average value, or the weighted value of the N4 fourth blind detection target numbers, and examples will be described together below.

[0118] Example 1: If the third sub-control resource includes SS#1, the number of PDCCH candidates in SS#1 in slot#1 is C1, and the number of PDCCH candidates in SS#1 in slot#2 is D1, then the fourth channel monitoring budget may 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.

[0119] Example 2: If the fourth sub-control resource includes SS#1 and SS#2, the weighting values of the PDCCH candidates in SS#1 and the PDCCH candidates in SS#2 in slot#1 are C2, and the weighting values of the PDCCH candidates in SS#1 and the PDCCH candidates in SS#2 in slot#2 are D2, then the fourth channel monitoring budget may 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 weighting value of C2 and D2.

[0120] Example 3: If the fourth sub-control resource includes SS#1 and SS#2, and SS#1 and SS#2 overlap only in a certain slot. That is, the above N time units are one slot, and in the overlapping slot, the number of PDCCH candidates in SS#1 is 4 and the number of PDCCH candidates in SS#2 is 2, then the fourth channel monitoring budget may be 4 + 2 = 6. Optionally, the above SS#1 and SS#2 may be the SSs used for the scheduling of the first cell.

[0121] Example 4: The weighting factor is 1, the fourth sub-control resource includes SS#1 and SS#2, SS#1 and SS#2 overlap in four consecutive 30 kHz slots, and these four slots may correspond to two 15 kHz slots. In the first overlapping 30 kHz slot, the number of PDCCH candidates for SS#1 is 4, and the number of PDCCH candidates for SS#2 is 4. In the second overlapping 30 kHz slot, the number of PDCCH candidates for SS#1 is 2, and the number of PDCCH candidates for SS#2 is 2. In the third overlapping 30 kHz slot, the number of PDCCH candidates for SS#1 is 4, and the number of PDCCH candidates for SS#2 is 4. In the fourth overlapping 30 kHz slot, the number of PDCCH candidates for SS#1 is 6, and the number of PDCCH candidates for SS#2 is 6. N4 time units are two consecutive 30 kHz slots within the time range of one 15 kHz slot. The fourth channel monitoring budget may be determined based on the weighting value of the PDCCH candidates in the third slot (i.e., 4 + 4) and the weighting value of the PDCCH candidates in the fourth slot (i.e., 6 + 6). That is, the fourth channel monitoring budget may be (4 + 4) + (6 + 6) = 20. Optionally, SS#1 and SS#2 above may be the SSs used for the scheduling of the first cell.

[0122] Example 5: The weighting coefficient is 1, the fourth sub-control resource includes SS#1 and SS#2, SS#1 and SS#2 overlap in 4 30kHz slots, and in the first overlapping slot, the number of PDCCH candidates of SS#1 is 4 and the number of PDCCH candidates of SS#2 is 4. In the second overlapping 30kHz slot, the number of PDCCH candidates of SS#1 is 2 and the number of PDCCH candidates of SS#2 is 2. In the third overlapping 30kHz slot, the number of PDCCH candidates of SS#1 is 3 and the number of PDCCH candidates of SS#2 is 4. In the fourth overlapping 30kHz slot, the number of PDCCH candidates of SS#1 is 6 and the number of PDCCH candidates of SS#2 is 6. N4 time units are 2 30kHz slots. Here, these 2 30kHz slots may or may not be consecutive. The fourth channel monitoring budget may be determined based on the weighted value of the PDCCH candidates in the first slot (i.e., 4 + 4) and the weighted value of the PDCCH candidates in the fourth slot (i.e., 6 + 6). That is, the fourth channel monitoring budget may be (4 + 4) + (6 + 6) = 20. Optionally, the above SS#1 and SS#2 may be the SSs used for the scheduling of the first cell.

[0123] Optionally, the N4 time units are N4 time units corresponding to the first reference subcarrier bandwidth.

[0124] For example, the N4 time units are slots corresponding to 1 15kHz.

[0126] In this embodiment, the above - mentioned M cells include the first cell, that is, the first cell supports self - scheduling.

[0127] Taking the example that the above - mentioned M cells include the first cell and the second cell, and the first cell is Cell#1 and the second cell is Cell#2, the above - mentioned first reference sub - carrier bandwidth may be the Cell#1 SCS, or the above - mentioned first reference sub - carrier bandwidth may be the Cell#2 SCS, or the above - mentioned first reference sub - carrier bandwidth may be max(Cell#1 SCS, Cell#2 SCS), or the above - mentioned first reference sub - carrier bandwidth may be min(Cell#1 SCS, Cell#2 SCS), or the above - mentioned first reference sub - carrier bandwidth may be a pre - configured SCS, or the above - mentioned first reference sub - carrier bandwidth may be an SCS predefined by a protocol, or the above - mentioned first reference sub - carrier bandwidth may be an SCS configured by a network - side device.

[0140] For example, the N4 time units are two consecutive 30 kHz slots.

[0141] Optionally, the N4 time units are N4 consecutive time units within a preset time range.

[0142] For example, the N4 time units are two consecutive 30 kHz slots within the time range of one 15 kHz slot.

[0153] At least one control resource or a specific control resource in the third cell is, for example, any SS in the third cell, or all SSs in the third cell, or a specific SS in the third cell.

[0154] Optionally, the joint channel monitoring budget between at least two of the M cells includes the joint channel monitoring budget between N cells, where the N cells are any N cells among the M cells, N is an integer greater than 1 and less than or equal to M, and the joint channel monitoring budget between the N cells is the joint channel monitoring budget supported by the terminal, a pre-configured joint channel monitoring budget, a joint channel monitoring budget predefined by the protocol, a joint channel monitoring budget configured by the network-side device, a second joint channel monitoring budget determined based on the control resource corresponding to at least one of the N cells, a third joint channel monitoring budget determined based on the reference configuration, a first joint channel monitoring budget determined based on at least one of the fourth joint channel monitoring budget determined based on the channel monitoring budget corresponding to at least one of the N cells.

[0155] In this embodiment, the above N cells may be any N cells out of the M cells.

[0156] The joint channel monitoring budget supported by the above terminal may be, for example, the joint channel monitoring budget supported by the terminal's capabilities. Optionally, the terminal may report the joint channel monitoring budget it supports to the network-side device to inform the network-side device of the capabilities of this terminal.

[0157] For the pre-configured joint channel monitoring budget, optionally, the terminal may report this pre-configured joint channel monitoring budget to the network-side device. For example, taking the pre-configured joint channel monitoring budget as the capabilities of the terminal, the terminal reports the pre-configured joint channel monitoring budget to the network-side device to inform the network-side device of the capabilities of the terminal.

[0158] For the joint channel monitoring budget configured by the network-side device, for example, the network-side device may instruct the terminal of the joint channel monitoring budget among the N cells by means of signaling such as SIB, DCI, RRC, or MAC CE.

[0159] The control resource corresponding to at least one cell among the above N cells is, for example, at least one SS of at least one cell among the above N cells.

[0160] The above reference configuration may include a reference subcarrier bandwidth.

[0161] Regarding the fourth joint channel monitoring budget determined based on the channel monitoring budget corresponding to at least one cell among the above N cells, examples will be described together below. For example, if N cells include a first cell and a second cell, the channel monitoring budget corresponding to the first cell is L1, the channel monitoring budget corresponding to the second cell is L2, and the fourth joint channel monitoring budget is L3, then L3 may be determined based on one of the following calculation formulas: γ2L3 = α2L1 + β2L2, where α2, β2, and γ2 are weight values. L3 = θ2 * L1, where θ2 is a weight value. L3 = Δ2 * L2, where Δ2 is a weight value. X3 / L1 + Y3 / L2 = L3, where X3 and Y3 are both positive integers. L1 / P3 + L2 / Q3 = L3, where P3 and Q3 are both positive integers. X4 / L1 + Y4 / L3 = 1, where X4 and Y4 are both positive integers. L1 / P4 + L3 / Q4 = 1, where P4 and Q4 are both positive integers. X5 / L2 + Y5 / L3 = 1, where X5 and Y5 are both positive integers. L2 / P5 + L3 / Q5 = 1, where P5 and Q5 are both positive integers.

[0162] Optionally, the first joint channel monitoring budget is the joint channel monitoring budget supported by the terminal, a pre-configured joint channel monitoring budget, a joint channel monitoring budget predefined by a protocol, a joint channel monitoring budget configured by a network-side device, a second joint channel monitoring budget, a third joint channel monitoring budget, a fourth joint channel monitoring budget, It includes one of the maximum value, minimum value, average value, or weighted value of at least two of the joint channel monitoring budget supported by the terminal, the pre-configured joint channel monitoring budget, the joint channel monitoring budget predefined by the protocol, the joint channel monitoring budget configured by the network-side device, the second joint channel monitoring budget, the third joint channel monitoring budget, and the fourth joint channel monitoring budget.

[0163] In this embodiment, the joint channel monitoring budget among N cells, i.e., the first joint channel monitoring budget, may be the joint channel monitoring budget supported by the terminal, or a pre-configured joint channel monitoring budget, or a joint channel monitoring budget predefined by a protocol, or a joint channel monitoring budget configured by network-side equipment, or a second joint channel monitoring budget, i.e., a joint channel monitoring budget determined based on the control resources corresponding to at least one cell among the N cells, or a third joint channel monitoring budget, i.e., a joint channel monitoring budget determined based on a reference configuration, or a fourth joint channel monitoring budget, i.e., a joint channel monitoring budget determined based on the channel monitoring budget corresponding to at least one cell among the N cells, or a channel monitoring budget calculated based on at least two of the above seven types of joint channel monitoring budgets. For example, the joint channel monitoring budget supported by the terminal is Lc, and the joint channel monitoring budget configured by network-side equipment is Ld, and the weighted value of Lc and Ld may be used as the first joint channel monitoring budget.

[0164] Optionally, the N cells include a first cell, and the second joint channel monitoring budget includes one of a carrier aggregation restriction monitoring budget corresponding to the first cell and a non-carrier aggregation restriction monitoring budget corresponding to the first cell.

[0165] In this embodiment, the carrier aggregation restriction monitoring budget corresponding to the first cell is the CA limited monitoring budget, and the non-carrier aggregation restriction monitoring budget corresponding to the first cell is the non CA limited monitoring budget.

[0166] Specifically, the non CA limited monitoring budget is also called the number of non CA limited monitoring, or the non CA limited blind detection budget or the number of non CA limited blind detections, or the non CA limited single cell budget or the number of non CA limited single cells, which is the maximum number M of PDCCH candidates in Table 2 or Table 3 max,slot,μ PDCCH and the maximum number C of non-overlapping CCEs max,slot,μ PDCCH and may include. The terminal may support simultaneously performing PDCCH blind detection according to the specified maximum processing capacity of PDCCH for N cap cells cells. That is, the blind detection ability of the UE is N cap cells non CA limited blind detection budgets, and the number of PDCCHs that the terminal supports for blind detection is at most non CA limited blind detection budget * N cap cells or the sum of the non CA limited blind detection budgets corresponding to this cell.

[0167] When the number of cells configured by the network side device exceeds N cap cells the number of PDCCH candidates and / or the number of CCEs that the terminal supports for blind detection is non CA limited blind detection budget * N cap cells or N cap cellsThe blind detection budget needs to be adjusted so as not to exceed the sum of the Non CA limited blind detection budgets corresponding to the individual cells. For example, the cells are grouped based on the scheduling cell SCS, adjusted based on the number of cells within the group, and the adjusted blind detection budget may not be the numerical values in Table 2 and Table 3 above, and may be, for example, larger or smaller. This adjusted blind detection budget may be referred to as the CA limited blind detection budget of the cell, M total,slot,μ PDCCH and C total,slot,μ PDCCH represented by.

[0168] Optionally, the reference configuration includes a second reference subcarrier bandwidth.

[0169] Optionally, the second reference subcarrier bandwidth is either the subcarrier bandwidth of any one of the N cells, the maximum subcarrier bandwidth among the subcarrier bandwidths of the N cells, or the minimum subcarrier bandwidth among the subcarrier bandwidths of the N cells.

[0170] Taking the example that the above N cells include Cell#1 and Cell#2, the second reference subcarrier bandwidth may be the Cell#1 SCS, or the second reference subcarrier bandwidth may be the Cell#2 SCS, or the second reference subcarrier bandwidth may be max(Cell#1 SCS, Cell#2 SCS), or the second reference subcarrier bandwidth may be min(Cell#1 SCS, Cell#2 SCS).

[0171] Optionally, the third joint channel monitoring budget includes the maximum channel monitoring budget among at least one channel monitoring budget corresponding to the second reference sub-carrier bandwidth.

[0172] For example, the third joint channel monitoring budget may be the maximum channel monitoring budget among the channel monitoring budgets corresponding to each time unit within the second reference sub-carrier bandwidth. Here, the channel monitoring budget corresponding to each time unit may be a weighted value of the number of blind detection targets of control resources corresponding to at least one cell among the above N cells within each time unit.

[0176] In another embodiment, the network-side device allocating the first control resource based on the second channel monitoring budget may be that the network-side device maps the first control resource based on the second channel monitoring budget. In this embodiment, the number of blind detection targets in one or more time units of the first control resource configured by the network-side device may not exceed the second channel monitoring budget, or the number of blind detection targets in one or more time units of the first control resource configured by the network-side device may exceed the second channel monitoring budget.

[0177] Optionally, when the number of blind detection targets in one or more time units of the first control resource constituted by the network-side device may exceed the second channel monitoring budget, the network-side device may allocate the first control resource according to the same allocation method as the terminal, so that the number of blind detection targets in the first control resource that the terminal needs to monitor within one or more time units exceeds the scheduling information that can be received when it is within the second channel monitoring budget. For example, map the blind detection targets in the first control resource according to a first preset rule until the mapped number of blind detection targets is greater than the second channel monitoring budget.

[0233] Hereinafter, examples of the present application will be described with examples. Here, the time unit in each example may be a slot, an occasion, a time span, etc. L1 may be a channel monitoring budget corresponding to cell#1 (i.e., the first cell), L2 is a channel monitoring budget corresponding to cell#2 (i.e., the second cell), and L3 is a joint channel monitoring budget between cell#1 and cell#2.

[0234] Example 1: One alternative embodiment where the number of PDCCH candidates or CCEs in the first control resource that may need to be monitored or actually need to be monitored within a specific or any N1 time units does not exceed L1 may be as follows. The first control resource is the CSS and USS in cell#1 (i.e., the first cell). That is, the number of PDCCH candidates or CCEs in the CSS and USS in cell#1 that may need to be monitored or actually need to be monitored within a specific or any N1 time units does not exceed L1. Here, the above time unit may be a slot, an occasion, a time span, etc. Further, one preferred embodiment is as follows. L1 is the maximum number of blind detection targets corresponding to one or more CSSs in the first cell in one time unit, or the maximum value of the sum of blind detection targets corresponding to one or more CSSs in the first cell in one time unit.

[0235] Another alternative embodiment where the number of PDCCH candidates or CCEs within a first control resource that may need to be monitored or actually need to be monitored within a specific or any N1 time units does not exceed L1 may be as follows. The first control resource is the USS in cell#1. That is, in cell#1, the number of PDCCH candidates or CCEs within the USS that may need to be monitored or actually need to be monitored within a specific or any N1 time units does not exceed L1. Further, one preferred embodiment is as follows. L1 is the maximum number of blind detection targets corresponding to one or more CSSs in the first cell within one time unit, or the maximum value of the sum of blind detection targets corresponding to one or more CSSs in the first cell within one time unit.

[0236] Another alternative embodiment where the number of PDCCH candidates or CCEs within a first control resource that may need to be monitored or actually need to be monitored within a specific or any N1 time units does not exceed L1 may be as follows. The first control resource is the CSS in cell#1. That is, in cell#1, the number of PDCCH candidates or CCEs within the CSS that may need to be monitored or actually need to be monitored within a specific or any N1 time units does not exceed L1. Further, one preferred embodiment is as follows. L1 is the maximum number of blind detection targets corresponding to one or more CSSs in the first cell within one time unit, or the maximum value of the sum of blind detection targets corresponding to one or more CSSs in the first cell within one time unit.

[0237] It should be noted that the above time unit may be a slot, an occasion, a time span, etc. L1 may 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.

[0238] For example, as shown in FIG. 7a, when L3 = 44 and L2 = 20, L1 = 44 - 20 = 24. There are SS#1 and SS#2 in cell#1, and SS#3 in cell#2. Here, SS#2 may be used for the scheduling of cell#1 by cell#2. Therefore, an example where the number of first control resources that may need to be monitored or actually need to be monitored within a specific or any N1 time units does not exceed L1 is as follows. 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 one slot does not exceed 44.

[0239] Also, for example, as shown in FIG. 7b, if the numbers in each SS in FIG. 7b are the number of PDCCH candidates within this SS in this slot, when scheduling cell#1 in slot2, the number of self-scheduling PDCCH candidates that need to be monitored in cell#1 is 16 + 16 = 32 > L1. Therefore, the user discards SS#2 in slot2 and does not map or monitor it.

[0240] Example 2: L2 with the same SCS For example, as shown in FIG. 7c, there are SS#1 and SS#2 in cell#1, and there is SS#3 in cell#2. Here, SS#2 may be used for the scheduling of cell#1 by cell#2, and cell#1 and cell#2 have the same SCS. In FIG. 7c, if the number in each SS represents the number of PDCCH candidates within this SS in this slot, then in slot2, the number of PDCCH candidates that may need to be monitored within SS#2 in cell#2 is 16.

[0241] Therefore, one optional implementation example where L2 is the maximum number of blind detection targets in the third sub-control resource that the terminal may need to monitor or actually needs to monitor in a specific or any N4 time units is as follows. N4 = 1, the time unit is a slot, the third sub-control resource is SS#2, the maximum number of blind detection targets is the maximum number of PDCCH candidates, and L2 = 16.

[0242] Example 3: L2 with Different SCS For example, as shown in FIG. 7d, without making any assumptions about the SS configuration in Cell#1, there are SS#1 and SS#2 in cell#2, cell#1 SCS = 15KHz, and cell#2 SCS = 30KHz. If the numbers in each SS in FIG. 7d represent the number of PDCCH candidates within this SS in this slot, then one optional embodiment where L2 is the maximum value of the weighted number of blind detection targets in a third sub-control resource that the terminal may need to monitor or actually needs to monitor in a specific or any N4 time units is as follows.
