[0043] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0044] I. New Radio (NR) Rel-15 Physical Downlink Control Channel (PDCCH) monitoring capability.

[0045] In NR Rel-15, the monitoring capability of PDCCH can be divided into mandatory and optional capabilities.

[0046] The capability to force a mandatory signal without capability is as follows:

[0047] 1) Control Resource Set (CORESET): Each BandWidth Part (BWP) of each cell can be configured with one additional CORESET on top of CORESET 0.

[0048] FR1: Bitmap of 6 Radio Bearer (RB) + 1 to 3 symbols.

[0049] FR2: For Type 0, 0A, 2 Common Search Space (CSS) and non-dedicated Radio Resource Control (RRC) configurations, the bitmap of 6RB is increased by 1 to 3 symbols; for Type 1, Type 3 and UE-specific Search Space (USS) configurations with dedicated RRC, the bitmap of 6RB is increased by 1 to 2 symbols.

[0050] Resource unit bundle size (REG bundle size): 2 / 3 / 6.

[0051] Interleaved and non-interleaved control channel element to resource element group mapping (CCE to REG mapping).

[0052] It supports configuring the precoder granularity size to the REG bundle size.

[0053] Supports scrambling with dedicated demodulation reference signals (DM-RS).

[0054] It supports configuring one or more Transport Configuration Indicator (TCI) states.

[0055] 2) Unicast PDCCH transmission in CSS and USS.

[0056] Aggregation Level (AL) 1, 2, 4, 8, 16.

[0057] For a scheduled secondary cell (Scell), each BWP has a maximum of 3 search space sets per slot (as defined by the scheduling cell), and this limitation applies before the search space (SS) is dropped.

[0058] For Type 1, Type 3, and USS with dedicated RRC configurations, monitoring occasions occur in the first three symbols of a slot.

[0059] For Type 0, 0A, 2CSS and Type 1 with non-dedicated RRC configurations, monitoring occasions can be in any one symbol of a slot and within a single span of a slot (3 consecutive Orthogonal Frequency Division Multiplex (OFDM) symbols).

[0060] 3) Supports monitoring downlink control information (DCI) 0_0, 0_1, 1_0, 1_1.

[0061] 4) For a Frequency Division Duplex (FDD) system, for each scheduled component carrier (CC), each slot processes only one DCI scheduled for DL ​​unicast transmission and one DCI scheduled for UL unicast transmission.

[0062] 5) For a Time Division Duplex (TDD) system, for each scheduled CC, each slot only processes one DCI scheduled for DL ​​unicast transmission and two DCI scheduled for UL unicast transmission.

[0063] The capabilities of mandatory signaling are as follows:

[0064] CORESET in FR2.

[0065] For Type 1, Type 3, and USS with dedicated RRC configurations, the bitmap of 6RB is plus 3 symbols.

[0066] The capabilities of Optional are as follows:

[0067] 1)pdcchMonitoringSingleOccasion.

[0068] FR1: Indicates that the UE supports receiving PDCCH scrambled with any 3 consecutive symbols in a 15 kHz slot using the Cell Radio Network Temporary Identifier (C-RNTI) and the Configured Scheduling Radio Network Temporary Identifier (CS-RNTI).

[0069] 2)pdcch-MonitoringAnyOccasions.

[0070] withoutDCI-gap: For Type 1, Type 3 and USS with dedicated RRC configurations, monitoring occurrences are any one symbol in a slot and comply with the blind decoding (BD) budget.

[0071] with DCI-gap: For Type 1, Type 3, and USS with dedicated RRC configurations, monotroing occasions may occur in any one symbol within a slot, but any two consecutive PDCCHs scrambled with C-RNTI, Modulation and Coding Scheme (MCS)-C-RNTI, or CS-RNTI must meet the following gap restrictions: 2 symbols for 15kHz, 4 symbols for 30kHz, 7 symbols for (60kHz, NCP), and 14 symbols for 120kHz, while also complying with BD budget constraints.

[0072] 3)pdcch-MonitoringAnyOccasionsWithSpanGap.

[0073] The span pattern is determined based on the (X, Y) values ​​of the UE reporting configured for all SS monitoring occasions.

[0074] The span pattern is the same for each slot.

[0075] The first span of the span pattern starts at the position of the first monitoring occasion in any slot. The span length is max{the maximum value of all CORESET durations and the minimum value of Y in the UE-reported candidate value}. The last span may be shorter. The next span starts at the position of the first monitoring occasion that is not included in the previous span.

[0076] Check if the span pattern satisfies at least one (X, Y) constraint of the reporting.

[0077] II. PDCCH monitoring capability of NR Rel-16.

[0078] In NR Rel-16, all PDCCH monitoring capabilities are optional, as shown below:

[0079] pdcch-Monitoring-r16: Unlike Rel15, it can report the value of the supported span for each physical downlink shared channel processing type (PerPDSCH processing type) and each subcarrier spacing (Per SCS), and each span conforms to the corresponding BD / Control Channel Element (CCE) limit.

[0080] pdcch-MonitoringMixed-r16: Supports different PDCCH monitoring capability configurations for different serving cells.

[0081] pdcch-MonitoringCA-r16: UE report pdcch-Monitoring-r16, configures the maximum number of monitoring cells when performing perspan BD and CCE restrictions, and indicates whether the span arrangement is aligned.

[0082] III. Handling of Hybrid PDCCH Monitoring Capabilities for NR Rel-16 UEs.

[0083] For NR Rel-16, there are the following two cell types:

[0084] Cell Type 1 (FR1 / FR2): Configured for slot-based PDCCH monitoring capability;

[0085] Cell Type 2 (FR1 only): Configured for span-based PDCCH monitoring capability.

[0086] For NR Rel-16 UEs, the following configuration cases may occur:

[0087] Case 1: All configured scheduling cells belong to cell type 1;

[0088] Case 2: All configured scheduling cells belong to cell type 2;

[0089] Case 3: At least one scheduled cell belongs to Cell Type 1, and at least one scheduled cell belongs to Cell Type 2.

[0090] Table 1 summarizes the relationship between UE reporting capabilities and base station configurability:

[0091] Table 1: Relationship between UE reporting capability and base station configurability

[0092]

[0093] For maximum processing capacity parameters, such as BG or CCE, the UE can report them separately for each supported case. Simultaneously, for each case, all cells can be grouped according to different PDCCH processing capabilities, and the maximum processing capacity parameters can be reported separately for each group.

[0094] The embodiments of this application will be described in detail below with reference to the accompanying drawings and through some examples and application scenarios.

[0095] See Figure 2 , Figure 2 This is one of the flowcharts of the PDCCH monitoring method provided in the embodiments of this application. Figure 2 The PDCCH monitoring method can be executed by the terminal. For example... Figure 2 As shown, the PDCCH monitoring method may include the following steps:

[0096] Step 201: The terminal receives first information, wherein the terminal supports at least multi-timeslot-based PDCCH monitoring capability, and the first information includes at least one of the following: search space configuration; PDCCH monitoring capability configuration.

[0097] In specific implementation, the network-side device can send the first information to the terminal to configure the terminal's SS through search space configuration and / or configure the terminal's PDCCH monitoring capabilities for each cell through PDCCH monitoring capability configuration. The PDCCH monitoring capability corresponding to a certain cell can be understood as: the terminal's PDCCH monitoring capability in that cell.

[0098] In this embodiment, the terminal supports PDCCH monitoring capability based on multiple time slots, meaning that the PDCCH monitoring capability can be defined based on the granularity of multiple time slots. Multiple time slots can be understood as at least two time slots.

[0099] In implementation, the support for multi-timeslot-based PDCCH monitoring capability can be specifically manifested as follows:

[0100] Supports PDCCH monitoring capabilities based on time slot groups;

[0101] Supports PDCCH monitoring capabilities based on slot-level span.

[0102] In other words, in this embodiment, the PDCCH monitoring capability can be defined at the granularity of time slot groups or at the granularity of time slot spans. A single time slot group may include at least two time slots; a single time slot span may include multiple time slots. In practical applications, the number of time slots included in a single time slot group and / or the number of time slots included in a single time slot span can be reported by the terminal, configured by the network-side device, or predefined by the protocol. The specific number can be determined according to the actual situation, and this embodiment does not limit this.

[0103] Step 202: The terminal determines the PDCCH monitoring capabilities corresponding to the N cells (N cells for the UE) of the terminal based on the first information, where N is an integer greater than 1.

[0104] In specific implementation, when the first information includes the PDCCH monitoring capability configuration, the PDCCH monitoring capabilities corresponding to the N cells can be determined based on the PDCCH monitoring capability configuration.

[0105] If the first information does not include the PDCCH monitoring capability configuration, the PDCCH monitoring capabilities corresponding to the N sub-districts can be predefined by the protocol.

[0106] Optionally, the PDCCH monitoring capabilities corresponding to the N cells may include at least one of the following:

[0107] Based on multi-timeslot PDCCH monitoring capabilities;

[0108] Time-slot-based PDCCH monitoring capability;

[0109] PDCCH monitoring capability based on symbol-level span.

[0110] It is understood that the PDCCH monitoring capabilities corresponding to the N cells are all PDCCH monitoring capabilities supported by the terminal; the PDCCH monitoring capabilities corresponding to the N cells can be the same or different, and can be determined according to the actual situation. This application embodiment does not limit this.

[0111] Step 203: The terminal monitors the PDCCH of the N cells according to the PDCCH monitoring capabilities corresponding to the N cells respectively.

[0112] In practice, the terminal can detect whether the search space configurations corresponding to the N cells meet the PDCCH monitoring capabilities of the N cells respectively. If they do, the terminal can monitor the PDCCH of the N cells according to the search space configurations corresponding to the N cells respectively.

[0113] The PDCCH monitoring method of this application involves a terminal configured with N cells and supporting multi-timeslot-based PDCCH monitoring capabilities. The terminal can monitor the PDCCH of the N cells according to their respective PDCCH monitoring capabilities. Therefore, the embodiments of this application increase the temporal granularity of defining PDCCH monitoring capabilities, thereby reducing the complexity of terminal implementation.

[0114] The implementation of step 203 will be explained in detail below.

[0115] Optionally, the terminal monitors the PDCCH of the N cells according to the PDCCH monitoring capabilities corresponding to the N cells, which may include:

[0116] The terminal determines the target restrictions corresponding to the N cells based on the PDCCH monitoring capabilities of each cell. The target restrictions include at least one of the following: restrictions on the temporal location of the PDCCH monitoring location; restrictions on the PDCCH processing parameters.

[0117] The terminal monitors the PDCCH of the N cells according to the target restrictions corresponding to the N cells.

[0118] In specific implementation, the time domain location restrictions of the PDCCH monitoring occasion may include at least one of the following: restrictions on the time slot where the PDCCH monitoring occasion is located; restrictions on the symbol where the PDCCH monitoring occasion is located.

[0119] The limitations of PDCCH processing parameters may specifically include at least one of the following: a limitation on the number of BDs; a limitation on the number of CCEs.

[0120] When determining the target restrictions corresponding to the N cells, the terminal can monitor the PDCCH of the N cells by using the target restrictions corresponding to the N cells, based on the relevant technology of monitoring PDCCH according to the restrictions. This will not be elaborated here.

[0121] In this embodiment of the application, the terminal can determine the target restrictions corresponding to the N cells by any of the following methods.

[0122] Method 1

[0123] Optionally, the terminal determines the target restrictions corresponding to the N cells based on the PDCCH monitoring capabilities of the N cells respectively, including:

[0124] If there are V cells in the N cells that correspond to PDCCH monitoring capabilities based on multiple time slots, and V is a positive integer, the terminal determines V first virtual cells that are equivalent to the V cells. The first virtual cells correspond to PDCCH monitoring capabilities based on time slots or PDCCH monitoring capabilities based on symbol-level spans.

[0125] Based on the PDCCH monitoring capabilities of the V first virtual cells and the PDCCH monitoring capabilities of the first cells, the target restrictions corresponding to the N cells are determined;

[0126] The first cell includes all cells other than the V cells among the N cells.

[0127] In Method 1, if there are cells with PDCCH monitoring capabilities based on multiple time slots among the N cells, the terminal can first determine all of these cells among the N cells, namely the V cells.

[0128] Subsequently, the terminal can convert each of the V cells into a virtual cell corresponding to a time-slot-based PDCCH monitoring capability or a symbol-level span-based PDCCH monitoring capability, thereby obtaining V first virtual cells. The terminal can then use the V first virtual cells and the first cells to calculate the target constraints corresponding to the N cells.

[0129] In this method, since the PDCCH monitoring capabilities of the V first virtual cells and the corresponding first cells are both time-slot-based PDCCH monitoring capabilities or symbol-level span-based PDCCH monitoring capabilities, the terminal can use the cell calculation target limit method of corresponding time-slot-based PDCCH monitoring capabilities or symbol-level span-based PDCCH monitoring capabilities in related technologies to calculate the target limit corresponding to the N cells, thereby reducing the complexity of terminal implementation.

[0130] The equivalent method is explained below.

[0131] Optionally, the terminal determines V first virtual cells equivalent to the V cells, including:

[0132] The terminal maps the PDCCH monitoring location of the second cell to the frame structure of the third cell. The first index of the subcarrier spacing (SCS) of the third cell satisfies any of the following: the first index is predefined; the first index is reported by the terminal or configured by the network-side equipment; the first index is equal to the ratio of the second index of the SCS of the first cell to X.

[0133] If the terminal determines the third cell as a first equivalent cell equivalent to the second cell when the PDCCH monitoring position of the frame structure of the third cell meets the first condition;

[0134] Wherein, the second cell is any one of the V cells;

[0135] The first condition is any one of the following: meeting the PDCCH monitoring capability based on the symbol-level span of the first index; meeting the PDCCH monitoring capability based on the time slot of the first index;

[0136] X satisfies at least one of the following: when the second cell has PDCCH monitoring capability based on time slot groups, X is the number of time slots X1 included in each time slot group; when the second cell has PDCCH monitoring capability based on time slot level spans, X is the minimum number of time slots X2 between consecutive time slot level spans.

[0137] In specific implementation, the terminal can first determine the index μ' of an SCS, and then select a cell with an SCS of μ' and corresponding PDCCH monitoring capability based on time slots or PDCCH monitoring capability based on symbol-level span as the third cell.

[0138] After determining the third cell, the terminal can map the PDCCH monitoring location of the second cell onto the frame structure of the third cell. Then, it determines whether the PDCCH monitoring location of the frame structure of the third cell conforms to the PDCCH monitoring capability based on a symbol-level span or time slot with an SCS of μ'. If it does, the second cell can be considered equivalent to the third cell; that is, the third cell is an equivalent cell to the second cell.

[0139] In this embodiment of the application, the index μ' of the SCS can be reported by the terminal, configured by the network-side device, or predefined by the protocol, or it can be determined based on the index μ of the SCS of the second cell.

[0140] When the index μ' of the SCS is determined based on the index μ of the SCS of the second cell, μ' and μ can satisfy: μ' = μ / X.

[0141] The value of X is related to the specific manifestation of the PDCCH monitoring capability corresponding to the second cell. When the second cell corresponds to PDCCH monitoring capability based on time slot groups, X is the number of time slots (X1) included in each time slot group; when the second cell corresponds to PDCCH monitoring capability based on time slot spans, X is the minimum interval number of time slots (X2) between consecutive time slot spans. In practical applications, X1 and / or X2 can be reported by the terminal, configured by network-side devices, or predefined by the protocol.

[0142] It should be noted that Method 1 can be used to determine at least one of the following: the time-domain location restrictions of the PDCCH monitoring locations corresponding to the N cells; and the restrictions of the PDCCH processing parameters corresponding to the N cells.

[0143] Method 2

[0144] In Method 2, the N cells can correspond to a set of J cells, where J is a positive integer.

[0145] In practice, each set of cells may include some or all of the N cells. It should be understood that at least one cell in each set of cells must be different.

[0146] Optionally, the J cell sets satisfy the following: one cell set corresponds to Z PDCCH monitoring capability types, where Z is a positive integer.

[0147] In the first implementation method, different PDCCH monitoring capability types can be divided into different cell sets.

[0148] In the second implementation, the first type of PDCCH monitoring capability and the second type of PDCCH monitoring capability can be assigned to the same cell group set, while other types of PDCCH monitoring capabilities can be assigned to another cell group set.

[0149] In the third implementation method, all types of PDCCH monitoring capabilities can be divided into the same cell group set.

[0150] It should be noted that the above implementation method is only an example and does not limit the way the cell set is determined.

[0151] For ease of understanding, assume that the N cells include cell 1, cell 2 and cell 3. Cell 1 corresponds to PDCCH monitoring capability based on multiple time slots; cell 2 corresponds to PDCCH monitoring capability based on time slots; and cell 3 corresponds to PDCCH monitoring capability based on symbol-level span.

[0152] Therefore, in the first implementation described above, the N cells correspond to 3 cell sets, and each cell set includes only one cell.

[0153] In the second implementation described above, the N cells correspond to two cell sets, one of which includes two cells and the other includes one cell.

[0154] In the third implementation described above, the N cells correspond to one cell set, which includes three cells.

[0155] Method two can be used to determine the limitations of the PDCCH processing parameters corresponding to the N cells. In Method two, the determination of the limitations of the PDCCH processing parameters corresponding to each cell set is related to whether the number of cells included in the cell set is greater than the maximum value of the cell capacity parameter corresponding to the cell set (also known as the maximum processing capacity cell capacity parameter). (Related) The number of cells included in the cell set is greater than the number corresponding to that cell set. In this case, the method for determining the limitations of the PDCCH processing parameters corresponding to the cell set is further related to the PDCCH monitoring capability type of the cells in the cell set, as explained below:

[0156] Method 1

[0157] Optionally, if all cells in the target cell set correspond to multi-slot-based PDCCH monitoring capabilities, the PDCCH processing parameters corresponding to the target cell set must satisfy at least one of the following:

[0158] Method 1-1: When all cells in the target cell set correspond to PDCCH monitoring capabilities based on time slot groups, and P cells are divided into at least one cell group based on the first rule, the sum of the PDCCH processing parameters of each time slot group of each cell group meets the first restriction of PDCCH processing parameters;

[0159] Method 1-2: When all cells in the target cell set correspond to PDCCH monitoring capabilities based on time slot groups, and P cells are divided into at least one cell group based on the second rule, the sum of the PDCCH processing parameters of the target time slot group of each cell group meets the first restriction of the PDCCH processing parameters. The target time slot group is the time slot group corresponding to the SCS with the maximum or minimum index in the cell group.

[0160] Method 1-3: When all cells in the target cell set correspond to PDCCH monitoring capabilities based on time slot span, and P cells are divided into at least one cell group based on the third rule, the sum of PDCCH processing parameters for each time slot span of each cell group meets the first restriction of PDCCH processing parameters.

[0161] Wherein, the P cells are the cells included in the target cell set; or, the P cells include: a second virtual cell equivalent to the fourth cell of the target cell set, and a fifth cell in the target cell set other than the fourth cell; the target cell set is any one of the cell sets in the J cell sets.

[0162] In determination method 1, all cells in the target cell set correspond to PDCCH monitoring capabilities based on multiple time slots. The terminal can first obtain at least one cell group based on the target cell set, and then determine the limitations of the PDCCH processing parameters corresponding to each cell group at the granularity of the cell group.

[0163] In specific implementation, the terminal can obtain at least one cell group through any of the following methods:

[0164] Implementation Method 1: The terminal can directly divide the cells in the target cell set to obtain at least one cell group. In this case, the P cells are the cells included in the target cell set.

[0165] Implementation Method Two: The terminal first converts some or all of the cells in the target cell set into equivalent virtual cells. Then, it groups the converted virtual cells and the unconverted virtual cells. In this case, the P cells may include: a second virtual cell equivalent to the fourth cell in the target cell set, and a fifth cell in the target cell set other than the fourth cell. Specifically, the number of cells in the fourth cell is equal to the number of cells in the second virtual cell, and the fourth cell includes at least one cell.

[0166] Furthermore, the cell group division method can be different for different performance forms of PDCCH monitoring capabilities based on multiple time slots; conversely, the cell group division method can be the same or different for the same performance form of PDCCH monitoring capabilities based on multiple time slots.

[0167] The implementation of determination method 1 will be explained in detail below, taking determination methods 1-1 to 1-3 as examples.

[0168] In both determination methods 1-1 and 1-2, the cells in the target cell set all correspond to PDCCH monitoring capabilities based on time slot groups. However, in determination methods 1-1 and 1-2, the terminal divides cell groups based on different rules. Therefore, the calculation methods for the PDCCH processing parameters corresponding to the cell groups in determination methods 1-1 and 1-2 are different.

[0169] In determination method 1-1, the P cells are divided into at least one cell group based on a first rule. The first rule can be reported by the terminal, configured by network-side devices, or predefined by the protocol. Optionally, the first rule may include:

[0170] Cells with the same first value and subcarrier spacing SCS index are grouped into one cell group;

[0171] The first value includes at least one of the following:

[0172] The number of time slots included in a time slot group is X1;

[0173] The time offset O1 of the starting time slot of the time slot group;

[0174] The number of configurable PDCCH monitoring locations Y1 within a time slot group.

[0175] That is, the terminal can group cells with at least one of X1, Y1, and O1 having the same SCS value of μ.

[0176] In this case, the sum of the PDCCH processing parameters for each time slot group in each cell group meets the first constraint of the PDCCH processing parameters.

[0177] In this embodiment, the first limitation can be reported by the terminal, configured by the network-side device, or predefined by the protocol. Specifically, the first limitation can be a target value, which is determined based on at least one of the following:

[0178] The maximum processing cell capacity parameter limit within the cell set;

[0179] Maximum PDCCH monitoring and processing parameter limit for a single cell in a cell group;

[0180] The total number of communities scheduled by the community group;

[0181] The number of neighborhood clusters.

[0182] It should be noted that for different community groups, and / or They can be the same or different for different cell groups. and / or They can be the same or different.

[0183] Optionally, the target value can be calculated using the following rounding down formula:

[0184]

[0185] That is, the target value is The floor value.

[0186] When the PDCCH processing parameters are expressed as the number of BDs, the sum of the PDCCH processing parameters for each time slot of each cell group meets the first constraint of the PDCCH processing parameters, which can be expressed as: the sum of the number of BDs for each time slot of each cell group is less than or equal to the target value.

[0187] When the PDCCH processing parameters are expressed as the number of CCEs, the sum of the PDCCH processing parameters for each time slot of each cell group meets the first constraint of the PDCCH processing parameters, which can be expressed as: the sum of the number of CCEs for each time slot of each cell group is less than or equal to the target value.

[0188] In determination method 1-2, the P cells are divided into at least one cell group based on a second rule. The second rule can be reported by the terminal, configured by the network-side equipment, or predefined by the protocol. The second rule can group cells that satisfy at least one of X1, O1, and Y1 and SCSμ according to certain conditions, which can be reported by the terminal, configured by the network-side equipment, or predefined by the protocol.

[0189] Optionally, the second rule may include:

[0190] Cells with the same second value are grouped into one cell group;

[0191] The second value includes at least one of the following:

[0192] A: The ratio of the number of time slots (X1) in a cell's time slot group to the cell's SCS index;

[0193] B: The ratio of the time offset O1 of the starting time slot of the cell's time slot group to the cell's SCS index;

[0194] C: The ratio of the number of configurable PDCCH monitoring locations Y1 within the cell's time slot group to the cell's SCS index.

[0195] That is, cells with an SCS of μ that are the same in at least one of A, B and C can be grouped together.

[0196] In this case, the sum of the PDCCH processing parameters of the target time slot group for each cell group meets the first constraint of the PDCCH processing parameters. The target time slot group is a time slot group in the cell group, specifically the time slot group corresponding to the SCS index with the maximum or minimum value in the cell group. That is, the sum of the PDCCH processing parameters of the time slot group corresponding to the maximum or minimum SCS index of each cell group meets the first constraint of the PDCCH processing parameters.

[0197] When the PDCCH processing parameters are expressed as the number of BDs, the sum of the PDCCH processing parameters of the target time slot group of each cell group meets the first limit of the PDCCH processing parameters, which can be expressed as: the sum of the number of BDs of the target time slot group of each cell group is less than or equal to the target value.

[0198] When the PDCCH processing parameters are expressed as the number of CCEs, the sum of the PDCCH processing parameters of the target time slot group of each cell group meets the first limit of the PDCCH processing parameters, which can be expressed as: the sum of the number of CCEs of the target time slot group of each cell group is less than or equal to the target value.

[0199] In determination methods 1-3, all cells in the target cell set correspond to PDCCH monitoring capabilities based on time slot-level span.

[0200] The P cells are divided into at least one cell group based on a third rule. The third rule can be reported by the terminal, configured by network-side devices, or predefined by the protocol.

[0201] Optionally, the third rule may include:

[0202] Cells with the same third value and subcarrier spacing SCS index are grouped into one cell group;

[0203] The third value includes at least one of the following:

[0204] Minimum number of time slots between consecutive time slot level spans x 2;

[0205] The maximum number of consecutive time slots Y2 in each time slot level span.

[0206] That is, cells with an SCS of μ that are the same in at least one of X2 and Y2 can be grouped together.

[0207] In this case, the sum of the PDCCH processing parameters for each time slot span of each cell group meets the first constraint of the PDCCH processing parameters.

[0208] When the PDCCH processing parameters are expressed as the number of BDs, the sum of the PDCCH processing parameters for each time slot span of each cell group meets the first constraint of the PDCCH processing parameters, which can be expressed as: the sum of the number of BDs for each time slot span of each cell group is less than or equal to the target value.

[0209] When the PDCCH processing parameters are expressed as the number of CCEs, the sum of the PDCCH processing parameters for each time slot span of each cell group meets the first constraint of the PDCCH processing parameters, which can be expressed as: the sum of the number of CCEs for each time slot span of each cell group is less than or equal to the target value.

[0210] In addition, for determination methods 1-3, optionally, the restrictions on the PDCCH processing parameters corresponding to the target cell set may also satisfy at least one of the following:

[0211] a) When the set of time slots where the PDCCH monitoring locations of the first cell group are located meets the (X2, Y2) constraint, the sum of the PDCCH processing parameters for each time slot span after the first cell group is set meets the first constraint of the PDCCH processing parameters.

[0212] b) If the set of time slots where the PDCCH monitoring locations of the first cell group are located does not meet the (X2, Y2) constraint, the sum of the PDCCH processing parameters of any combination of time slot level spans of different cells in the first cell group meets the first constraint of PDCCH processing parameters.

[0213] Wherein, the first cell group is any one of the at least one cell group; X2 is the minimum number of time slots between consecutive time slot level spans; Y2 is the maximum number of consecutive time slots for each time slot level span.

[0214] In a), the time slot span after aggregating the first cell group can be understood as: the time slot span determined based on the merged time slots after merging (i.e., aggregating) the time slots where the PDCCH monitoring locations of the first cell group are located. That is, different cells in the first cell group take one time slot span.

[0215] In b), each cell in the first cell group takes a time slot-level span.

[0216] Method 2

[0217] Optionally, when the target cell set includes a first portion of cells and a second portion of cells, wherein the cells in the first portion of cells all correspond to PDCCH monitoring capabilities based on multi-slots, and the cells in the second portion of cells correspond to PDCCH monitoring capabilities based on slots or symbol-level spans, the terminal determines the target restrictions corresponding to the N cells based on the PDCCH monitoring capabilities corresponding to the N cells, including:

[0218] A third virtual cell is determined that corresponds to the first group of cells. The third virtual cell corresponds to either time-slot-based PDCCH monitoring capability or symbol-level span-based PDCCH monitoring capability.

[0219] Based on the PDCCH monitoring capabilities of the third virtual cell and the second set of cells, the limitations of the PDCCH processing parameters corresponding to the target cell set are determined.

[0220] In determination method 2, the first part of the target cell set corresponds to PDCCH monitoring capabilities based on multi-slot time slots, and the second part of the cells corresponds to PDCCH monitoring capabilities based on symbol-level spans or time slots. In this method, the terminal can first convert the first part of the cells into virtual cells, and then use the third virtual cell and the second part of the cells to determine the target restrictions corresponding to the N cells.

[0221] It should be noted that the method for determining the PDCCH processing parameter restrictions corresponding to the target cell set in Method 2 is similar to the method for determining the target restrictions corresponding to the N cells in Method 1. Both methods use converted virtual cells and unconverted cells to determine the corresponding restrictions, and both the converted virtual cells and unconverted cells correspond to PDCCH monitoring capabilities based on symbol-level span or time slot. The difference lies in the fact that Method 2 determines the restrictions on the PDCCH processing parameters corresponding to the target cell set, while Method 1 determines the target restrictions corresponding to the N cells.

[0222] The following explains the PDCCH monitoring capabilities of the corresponding cell:

[0223] Optionally, the PDCCH monitoring capability corresponding to the cell is any one of the following:

[0224] The PDCCH monitoring capability corresponding to the BWP in the active bandwidth portion of the cell;

[0225] The PDCCH monitoring capability of the virtual cell corresponding to the cell.

[0226] When the PDCCH monitoring capability of a cell is the same as the PDCCH monitoring capability of the cell's active BWP, different BWPs of the cell can correspond to the same PDCCH monitoring capability or different PDCCH monitoring capabilities. The specifics can be determined according to the actual situation, and this application embodiment does not limit this.

[0227] When the PDCCH monitoring capability of the cell is the same as the PDCCH monitoring capability of the virtual cell, after the terminal determines the PDCCH monitoring capability of the cell as predefined by the protocol or configured by the network-side device, it can convert the cell into a virtual cell. Then, it can determine the PDCCH monitoring capability of the virtual cell as the PDCCH monitoring capability of the cell, that is, update the PDCCH monitoring capability of the cell to the PDCCH monitoring capability of the virtual cell.

[0228] As mentioned above, the PDCCH monitoring capability of a cell can be configured by network-side equipment. In this case, optionally, the PDCCH monitoring capability of the cell is determined based on SCS.

[0229] In this optional embodiment, since there is a correspondence between the SCS and the PDCCH monitoring capability, the network-side device can implicitly indicate the PDCCH monitoring capability corresponding to the cell by indicating the SCS. Of course, it is understood that in other embodiments, the network-side device can explicitly indicate the PDCCH monitoring capability corresponding to the cell.

[0230] In this embodiment, before receiving the first information, the terminal can report its supported PDCCH capability information to the network-side device. This allows the network-side device to configure the terminal's search space and / or PDCCH monitoring capabilities based on the terminal's supported PDCCH capabilities, thereby increasing the probability that the SS configuration of the N cells conforms to the PDCCH monitoring capabilities corresponding to each of the N cells. Specific details are as follows:

[0231] Optionally, before the terminal receives the first information, the method may further include:

[0232] The terminal sends a second message, which is used to indicate the terminal's PDCCH monitoring capability information.

[0233] Optionally, the PDCCH monitoring capability information may include at least one of the following:

[0234] 1) The first sub-information is used to indicate whether the terminal supports PDCCH monitoring capability based on multiple time slots;

[0235] 2) The second sub-information is used to indicate whether the terminal supports different PDCCH monitoring capabilities for different bandwidth portions of the same cell;

[0236] 3) The third sub-information is used to indicate whether the terminal supports different PDCCH monitoring capabilities corresponding to different cells;

[0237] 4) The maximum value of the capacity parameters of the G cells, where G is a positive integer.

[0238] For 1)

[0239] Optionally, the first sub-information may specifically be used to indicate at least one of the following:

[0240] Does the terminal support PDCCH monitoring capability based on time slot groups?

[0241] Does the terminal support PDCCH monitoring capability based on time slot span?

[0242] Optionally, if the first sub-information indicates that the terminal supports PDCCH monitoring capability based on time slot groups, the PDCCH monitoring capability information may further include at least one of the following:

[0243] The number of time slots included in a time slot group is X1;

[0244] The time offset O1 of the starting time slot of the time slot group;

[0245] The number of configurable PDCCH monitoring locations Y1 within a time slot group.

[0246] Optionally, when the first sub-information indicates that the terminal supports PDCCH monitoring capability based on time slot span, the PDCCH monitoring capability information may further include at least one of the following:

[0247] Minimum number of time slots between consecutive time slot level spans x 2;

[0248] The maximum number of consecutive time slots Y2 in the time slot level span;

[0249] The number of time slots M contained in a unit of time corresponding to the time slot level span;

[0250] The time offset O2 per unit time corresponding to the time slot level span.

[0251] For 2)

[0252] The second piece of information can be used to indicate whether the terminal supports the ability to monitor different bandwidth portions of the same cell using a hybrid PDCCH.

[0253] For 3), the third sub-information is used to indicate whether the terminal supports the ability to monitor different cells using a hybrid PDCCH.

[0254] In specific implementation, the hybrid PDCCH monitoring capability may include at least two of the following:

[0255] Based on multi-timeslot PDCCH monitoring capabilities;

[0256] Time-slot-based PDCCH monitoring capability;

[0257] PDCCH monitoring capability based on symbol-level span.

[0258] For 4)

[0259] Optionally, when the PDCCH monitoring capability information includes the maximum values ​​of G cell capacity parameters, the maximum values ​​of the G cell capacity parameters correspond to a target scenario, and the target scenario includes at least one of the following scenarios:

[0260] All N cells are matched with time-slot-based PDCCH monitoring capabilities;

[0261] All N cells are matched with PDCCH monitoring capabilities based on symbol set span;

[0262] At least one of the N cells is matched with time slot-based PDCCH monitoring capability, and at least one cell is matched with symbol set span-based PDCCH monitoring capability.

[0263] Each of the N cells corresponds to a PDCCH monitoring capability based on multiple time slots;

[0264] At least one of the N cells corresponds to the multi-timeslot PDCCH monitoring capability, and at least one cell corresponds to the timeslot-based PDCCH monitoring capability.

[0265] At least one of the N cells corresponds to the multi-timeslot PDCCH monitoring capability, and at least one cell corresponds to the symbol-level span-based PDCCH monitoring capability.

[0266] At least one of the N cells corresponds to the multi-timeslot PDCCH monitoring capability, at least one cell corresponds to the timeslot-based PDCCH monitoring capability, and at least one cell corresponds to the symbol-level span-based PDCCH monitoring capability.

[0267] In other words, at least one scenario in the target scenario can share the maximum values ​​of the G cell capacity parameters. It is understood that the number of scenarios and / or specific scenarios corresponding to different maximum values ​​of the G cell capacity parameters can be the same or different.

[0268] Matching a cell with a specific PDCCH monitoring capability can be understood as: the cell corresponds to that PDCCH monitoring capability, or, the equivalent virtual cell corresponds to that PDCCH monitoring capability. For example, if all N cells are matched with slot-based PDCCH monitoring capabilities, it can be understood as: all N cells correspond to or are equivalent to slot-based PDCCH monitoring capabilities.

[0269] In specific implementation, for any of the above scenarios, the terminal can divide the N cells into at least one cell set, and the maximum value of the capacity parameters of the G cells can include the maximum value of the capacity parameters of the cells corresponding to the at least one cell set.

[0270] The following explains the time-domain location limitations of the PDCCH monitoring location in the cell.

[0271] First, the limitations of the time slot where the PDCCH monitoring location is located will be explained.

[0272] Optionally, when a cell corresponds to a multi-timeslot-based PDCCH monitoring capability, the time slot where the cell's PDCCH monitoring location is located satisfies at least one of the following:

[0273] When the cell has PDCCH monitoring capability based on time slot groups, the time slot where the cell's PDCCH monitoring location is located satisfies the first condition;

[0274] When a cell has PDCCH monitoring capability based on time slot span, and the time slot span pattern is determined based on the fourth rule, the time slot where the cell's PDCCH monitoring location is located satisfies the following: the distance between the starting time slots of consecutive time slot spans is not less than X2 time slots, where X2 is the minimum number of time slots between consecutive time slot spans.

[0275] In this optional implementation, the conditions that the time slot where the cell's PDCCH monitoring location is located can satisfy may be different for different forms of PDCCH monitoring capabilities based on multiple time slots.

[0276] When the cell has PDCCH monitoring capability based on time slot groups, the terminal can determine the slot group location based on X1 and / or O1, and the time slot where the PDCCH monitoring location configured in the cell is located can meet the first condition.

[0277] Optionally, the first condition may include at least one of the following:

[0278] Within the first Y1 time slots of the time slot group;

[0279] Within a consecutive Y1 time slot of the time slot group;

[0280] The number of time slots in the time slot group is no greater than Y1;

[0281] Where Y1 is the number of configurable PDCCH monitoring locations within the time slot group.

[0282] The time slot group in the first condition can be understood as at least one defined slot group. For example, if the time slot is within the first Y1 time slots of the time slot group, it can be understood as: the time slot is within the first Y1 time slots of the defined time slot group.

[0283] When a cell has PDCCH monitoring capabilities based on slot-level spans, the slot-level span pattern, i.e., the slot-granular span pattern, can be determined according to the slot location of the PDCCH monitoring location and the fourth rule. In this case, the slot where the PDCCH monitoring location is located can satisfy the following condition: the distance between the starting slots of any consecutive slot-level span is not less than X2 slots.

[0284] Optionally, when the time slot span corresponds to Q unit time, where Q is an integer greater than 1, the fourth rule includes at least one of the following:

[0285] Rule 1: Within the first unit of time, the starting position of the first time slot level span is the first time slot within the first unit of time, which is the first time slot configured with a PDCCH monitoring position within the first unit of time; the starting position of the (i+1)th time slot level span is the second time slot, which is configured with a PDCCH monitoring position and is different from the first time slot of the ith time slot level; the maximum length of the time slot level span is Y2 time slots;

[0286] Rule 2: Within the first unit of time, the starting position of the first time slot level span is the third time slot within the first unit of time. The index number of the third time slot is the same as the index number of the fourth time slot. The fourth time slot is the time slot with the smallest index among the time slots configured with PDCCH monitoring positions within the Q unit of time. The starting position of the (i+1)th time slot level span is the second time slot. The second time slot is configured with a PDCCH monitoring position and is different from the first time slot of the i-th time slot level. The maximum length of the time slot level span is Y2 time slots.

[0287] Wherein, the first unit time is any one of the Q unit times; Y2 is the maximum number of consecutive time slots in the time slot level span; and i is a positive integer.

[0288] In Rule 1, since the starting position of the first slot-level span within each unit time is the first slot within that unit time that is configured with PDCCH monitoring positions, i.e., the first slot of that unit time, the span patterns of the slot granularity in different units of the Q unit time may be the same or different, depending on the first slot of each unit time. For any two unit times, if the first slots of these two unit times are different, then the span patterns of the slot granularity of these two time units are different; if the first slots of these two unit times are the same, then the span patterns of the slot granularity of these two time units can be the same.

[0289] In Rule 2, since the starting position of the first slot-level span in each unit of time is the same as the index number of the fourth slot, the starting position of the first slot-level span in each unit of time is the same. Therefore, the span pattern of the slot granularity is the same in different units of time within the Q units of time, that is, the span pattern of the slot granularity repeats in each unit of time within the Q units of time.

[0290] Secondly, the limitations on the symbols used for PDCCH monitoring locations are explained.

[0291] Optionally, when the cell corresponds to multi-timeslot-based PDCCH monitoring capability, the symbol of the cell's PDCCH monitoring location satisfies at least one of the following:

[0292] The symbol at the location of the PDCCH monitoring point in the cell satisfies the second condition;

[0293] When the symbol-level span pattern is determined based on the fifth rule, the distance between the starting symbols of consecutive symbol-level spans of the cell's PDCCH monitoring location is not less than X' symbols, where X' is a positive integer.

[0294] In this optional embodiment, the restriction on the symbol where the PDCCH monitoring location is located can be implemented at the granularity of a single symbol or at the granularity of a single symbol-level span. For different granularities, the conditions that the symbol where the PDCCH monitoring location is located must satisfy can be different, as detailed below:

[0295] When the restriction on the symbol where the PDCCH monitoring location is located is performed at the granularity of a single symbol, the symbol where the PDCCH monitoring location is located can satisfy the second condition.

[0296] Optionally, the second condition may include at least one of the following:

[0297] Within the first Y' symbols of the time slot;

[0298] Within a consecutive Y' symbols of the time slot;

[0299] The number of symbols in a time slot is no greater than Y';

[0300] Where Y' is a positive integer. Y' can be reported by the terminal, configured by the network-side device, or predefined by the protocol.

[0301] The time slot in the second condition can be understood as any time slot where the PDCCH monitoring location is located.

[0302] When the restriction on the symbol where the PDCCH monitoring location is located is applied at the granularity of a single symbol-level span, the pattern of the symbol-level span, i.e., the span pattern at the symbol granularity, can be determined based on the symbol where the PDCCH monitoring location is located and the fifth rule. In this case, the symbol where the PDCCH monitoring location is located can satisfy the following condition: the distance between the starting symbols of any consecutive symbol-level span is not less than X' symbols.

[0303] Optionally, when the symbolic span corresponds to K units of time, and K is an integer greater than 1, the fifth rule includes at least one of the following:

[0304] Rule 3: In the second unit of time, the starting position of the first symbol-level span is the first symbol in the second unit of time, which is the first symbol configured with a PDCCH monitoring position in the first unit of time; the starting position of the (i+1)th symbol-level span is the second symbol, which is configured with a PDCCH monitoring position and is different from the first symbol of the i-th symbol level; the maximum length of the symbol-level span is Y' symbols.

[0305] Rule 4: In the second unit of time, the starting position of the first symbol-level span is the third symbol in the first unit of time, and the index number of the third symbol is the same as the index number of the fourth symbol. The fourth symbol is the symbol with the smallest index among the symbols configured with PDCCH monitoring positions in the K unit of time. The starting position of the (i+1)th symbol-level span is the second symbol, which is configured with a PDCCH monitoring position and is different from the first symbol of the i-th symbol level. The maximum length of the symbol-level span is Y' symbols.

[0306] Wherein, the second unit time is any one of the K unit times; Y' is a positive integer; and i is a positive integer.

[0307] In Rule 3, since the starting position of the first symbol-level span in each unit time is the first symbol configured with PDCCH monitoring positions in that unit time, i.e., the first symbol of that unit time, the span patterns of the symbol granularity in different units of the Q unit time may be the same or different, depending on the first symbol of each unit time. For any two unit times, if the first symbols of these two unit times are different, then the span patterns of the symbol granularity of these two time units are different; if the first symbols of these two unit times are the same, then the span patterns of the symbol granularity of these two time units can be the same.

[0308] In rule 4, since the starting position of the first symbol-level span in each unit time is the same for symbols with the same index number as the fourth symbol, the starting position of the first symbol-level span in each unit time is the same. Therefore, the span pattern of the symbol granularity is the same in different units of time within the Q units of time, that is, the span pattern of the symbol granularity repeats in each unit time within the Q units of time.

[0309] In this embodiment of the application, when the cell corresponds to multi-timeslot-based PDCCH monitoring capability, the limitations of the cell's PDCCH processing parameters can also be determined in the following ways:

[0310] Optionally, the PDCCH processing parameters of the cell must satisfy at least one of the following:

[0311] When a cell has PDCCH monitoring capability based on time slot groups, the sum of the PDCCH processing parameters for each time slot group in the cell meets the first limitation of the PDCCH processing parameters.

[0312] When a cell has PDCCH monitoring capability based on time slot spans, and the time slot span pattern is determined based on the fifth rule, the sum of the restrictions on the PDCCH processing parameters for each time slot span of the cell conforms to the first restriction on the PDCCH processing parameters.

[0313] When the cell has PDCCH monitoring capability based on time slot groups, the terminal can determine the slot group location based on X1 and / or O1, and the total PDCCH processing parameters of the search space configured for each slot group meet the first restriction.

[0314] When a cell corresponds to PDCCH monitoring capabilities based on slot-level spans, the slot-level span pattern can be determined according to the slot location of the PDCCH monitoring location and the fourth rule. In this case, the total PDCCH processing parameters configured in the search space of each slot levelspan meet the first constraint.

[0315] In this optional embodiment, the PDCCH processing parameters of each cell are limited in accordance with the PDCCH monitoring and processing parameter limits corresponding to the PDCCH monitoring capabilities determined for each cell.

[0316] As can be seen from the foregoing, the terminal in this application embodiment at least supports multi-timeslot-based PDCCH monitoring capability. Optionally, in this application embodiment, a restriction can be added to the support for multi-timeslot-based PDCCH monitoring capability. Specifically, this restriction can be predefined by the protocol or reported by the terminal. The following provides a detailed explanation of this restriction.

[0317] Optionally, if U cells out of the N cells have PDCCH monitoring capabilities based on multiple time slots, where U is an integer greater than 1, then the U cells satisfy the third condition.

[0318] In this optional implementation, the limitation on the support for multi-slot-based PDCCH monitoring capability is specifically manifested in the limitation on the U cells, which can restrict the U cells from having consistency by satisfying a third condition.

[0319] In practice, the U cells may have at least two cells with the same SCS, or all cells may have different SCS. The third condition may vary depending on the specific circumstances.

[0320] For cells with the same SCS, the third condition may optionally include at least one of the following:

[0321] In the case of the PDCCH monitoring capability corresponding to the U cells based on time slot groups, the third condition includes at least one of the following: the number of time slots X1 included in the time slot group is the same; the time offset O1 of the starting time slot of the time slot group is the same; and the number Y1 of configurable PDCCH monitoring locations within the time slot group is the same.

[0322] When the U cells correspond to PDCCH monitoring capabilities based on time slot spans, the third condition includes at least one of the following: X2 is the same; Y2 is the same; (X2, Y2) of the U cells is the same, and the set of time slots where the PDCCH monitoring locations of the U cells are located meets the (X2, Y2) constraint; wherein, X2 is the minimum number of time slots between consecutive time slot spans; Y2 is the maximum number of consecutive time slots for each time slot span.

[0323] In other words, given the PDCCH monitoring capability based on time slot groups for the U cells, the consistency of cells with the same SCS can be expressed as: at least one of X1, O1, and Y1 of these cells is the same.

[0324] In the case where the U cells correspond to PDCCH monitoring capabilities based on time slot spans, the consistency of cells with the same SCS can include at least one of the following: these cells have the same X2; these cells have the same Y2; for cells with the same (X2, Y2), the set of time slots where the PDCCH monitoring locations of these cells are located still meets the (X2, Y2) constraint, and further, any span is within Y2 time slots.

[0325] For cells with different SCS, optionally, if there are a fifth cell and a sixth cell with different SCS among the U cells, the third condition includes at least one of the following:

[0326] The sixth cell is a virtual cell of the fifth cell;

[0327] The first ratio equals the second ratio;

[0328] Wherein, the first ratio is the ratio of the fourth value to the SCS index of the fifth cell, and the second ratio is the ratio of the fourth value to the SCS index of the sixth cell;

[0329] The fourth value includes at least one of the following:

[0330] The number of time slots included in a time slot group is X1;

[0331] The time offset O1 of the starting time slot of the time slot group;

[0332] The number of configurable PDCCH monitoring locations Y1 within a time slot group.

[0333] For ease of understanding, assume that the SCS of the fifth cell is μ1 and the SCS of the sixth cell is μ2.

[0334] In this case, the consistency between the fifth cell and the sixth cell may include at least one of the following:

[0335] The sixth cell is a virtual cell of the fifth cell;

[0336] The X1 values ​​of the fifth cell and the sixth cell meet certain conditions, such as: X1 / μ1 of the fifth cell = X1 / μ2 of the sixth cell;

[0337] The O1 values ​​of the fifth cell and the sixth cell meet certain conditions, such as: O1 / μ1 of the fifth cell = O1 / μ2 of the sixth cell;

[0338] The Y1 values ​​of the fifth cell and the sixth cell meet certain conditions, such as: Y1 / μ1 of the fifth cell = Y1 / μ2 of the sixth cell.

[0339] In specific implementation, the sixth cell is a virtual cell of the fifth cell. Specifically, this can be manifested as follows: when the PDCCH monitoring position of the fifth cell is mapped onto the frame structure of the sixth cell, the PDCCH monitoring position of the frame structure of the sixth cell conforms to the multi-slot PDCCH monitoring capability based on the fourth index. In this case, both the cell and its equivalent virtual cell correspond to multi-slot PDCCH monitoring capability.

[0340] As described above, different cells in this application embodiment can support mixed PDCCH monitoring capabilities, and different BWPs in the same cell can support mixed PDCCH monitoring capabilities. Optionally, in this application embodiment, restrictions on the support for mixed PDCCH monitoring capabilities can be added. Specifically, these restrictions can be predefined by the protocol or reported by the terminal. The following provides a detailed explanation of these restrictions.

[0341] Optionally, the N cells include at least two PDCCH monitoring capabilities if at least one of the following conditions is met;

[0342] Support designating the seventh cell as the eighth cell in a virtual cell;

[0343] Support designating the eighth cell as a virtual cell, similar to the seventh cell;

[0344] The seventh cell corresponds to PDCCH monitoring capability based on multiple time slots; the seventh cell corresponds to PDCCH monitoring capability based on time slots or PDCCH monitoring capability based on symbol-level span.

[0345] The support for identifying the seventh cell as the eighth cell in a virtual cell can be understood as: the consistency / conversion between cells based on multi-slot PDCCH monitoring capabilities and cells based on symbol-level span / slot PDCCH monitoring capabilities.

[0346] In this case, for a cell with an SCS of μ based on multi-slot PDCCH monitoring capability, all its configured PDCCH monitoring occasions are mapped to the frame structure with an SCS of μ', which conforms to the PDCCH monitoring capability reported by the UE based on symbol-level span / slot with an SCS of μ'.

[0347] The ability to identify the eighth cell as the seventh cell in a virtual cell can be understood as the consistency / conversion between cells with PDCCH monitoring capabilities based on symbol-level spans / time slots and those with PDCCH monitoring capabilities based on multiple time slots.

[0348] In this case, for a cell with an SCS of μ based on symbol-level span / slot PDCCH monitoring capability, all its configured PDCCH monitoring occasions are mapped to the frame structure with an SCS of μ', which is consistent with the UE's reported multi-slot PDCCH monitoring capability based on an SCS of μ.

[0361] Optionally, if the first sub-information indicates that the terminal supports PDCCH monitoring capability based on time slot groups, the PDCCH monitoring capability information further includes at least one of the following:

[0362] The number of time slots included in a time slot group is X1;

[0363] The time offset O1 of the starting time slot of the time slot group;

[0364] The number of configurable PDCCH monitoring locations Y1 within a time slot group.

[0365] Optionally, if the first sub-information indicates that the terminal supports PDCCH monitoring capability based on time slot span, the PDCCH monitoring capability information further includes at least one of the following:

[0368] The number of time slots M contained in a unit of time corresponding to the time slot level span;

[0369] The time offset O2 per unit time corresponding to the time slot level span.

[0370] Optionally, when the PDCCH monitoring capability information includes the maximum values ​​of G cell capacity parameters, the maximum values ​​of the G cell capacity parameters correspond to a target scenario, and the target scenario includes at least one of the following scenarios:

[0371] All N cells are matched with time-slot-based PDCCH monitoring capabilities;

[0372] All N cells are matched with PDCCH monitoring capabilities based on symbol set span;

[0373] At least one of the N cells is matched with time slot-based PDCCH monitoring capability, and at least one cell is matched with symbol set span-based PDCCH monitoring capability.

[0374] Each of the N cells corresponds to a PDCCH monitoring capability based on multiple time slots;

[0375] At least one of the N cells corresponds to the multi-timeslot PDCCH monitoring capability, and at least one cell corresponds to the timeslot-based PDCCH monitoring capability.

[0376] At least one of the N cells corresponds to the multi-timeslot PDCCH monitoring capability, and at least one cell corresponds to the symbol-level span-based PDCCH monitoring capability.

[0387] 2. The PDCCH monitoring capability information includes at least one of the following:

[0388] Whether multi-slot-based PDCCH monitoring capability is supported can be indicated by explicit or implicit means (e.g., by whether a specific SCS is supported).

[0389] Does it support PDCCH monitoring capabilities based on fixed slot groups? If so, it includes one or more of the following:

[0390] The size X of the fixed slot group;

[0391] The time offset O of the starting slot of the fixed slot group;

[0393] Does it support PDCCH monitoring capabilities based on slot-level spans? If so, it includes one or more of the following:

[0394] The minimum number of slots (X) between consecutive spans based on slot granularity;

[0398] Does it support the use of mixed PDCCH monitoring capabilities for different BWPs within the same cell?

[0399] Does it support the use of hybrid PDCCH monitoring capabilities in different cells?

[0400] The hybrid PDCCH monitoring capability includes one or more of the following: PDCCH monitoring capabilities based on multiple time slots, time slots, and / or symbol-level spans.

[0402] PDCCH monitoring capabilities based on multiple time slots and symbol-level spans;

[0403] PDCCH monitoring capability based on multiple time slots + time slots + symbol-level spans.

[0404] 3. The PDCCH monitoring capability information includes one or more maximum processing capacity cell capacity parameters, and for at least one set of cells in at least one of the following scenarios, wherein the cell set is grouped by cells using one or more specific PDCCH monitoring capability types (e.g., cells with different PDCCH monitoring capability types are grouped as a set):

[0405] All cells adopt or have equivalent time-slot-based PDCCH monitoring capabilities.

[0406] All cells employ or have equivalent PDCCH monitoring capabilities based on symbol-level spans.

[0407] At least one cell employs or is equivalent to slot-based PDCCH monitoring capability, and at least one cell employs or is equivalent to symbol-level span-based PDCCH monitoring capability.

[0413] 4. The determination of the PDCCH monitoring capability type for each cell includes at least one of the following:

[0414] The type of PDCCH monitoring capability is determined based on the PDCCH monitoring capability configured for the cell by the base station;

[0415] The PDCCH monitoring capability type of the active BWP in a cell serves as the PDCCH monitoring capability type for that cell. The PDCCH monitoring capability type of the active BWP can be explicitly configured by the base station or implicitly obtained through other configurations (such as SCS configuration).

[0416] For cells with an SCS of μ that are determined to have PDCCH monitoring capability based on multi-slots as described above, they can be equivalent to virtual cells with an SCS of μ' that are based on PDCCH monitoring capability based on symbol-level span / slot. In this case, the PDCCH monitoring capability type of the cell is determined to be the PDCCH monitoring type of the virtual cell. These virtual cells and cells with PDCCH monitoring capability based on symbol-level span / slot are then processed together for subsequent processing, such as maximum processing capability parameters, BD / CCE calculation, etc.

[0417] An equivalent approach could be: for a cell with an SCS of μ based on multi-slot PDCCH monitoring capability, all its configured PDCCH monitoring occasions are mapped to a frame structure with an SCS of μ', conforming to the UE-reported symbol-level span / slot PDCCH monitoring capability based on SCS of μ'. The μ' is predefined (e.g., 120kHz), or μ' is equal to μ / X.

[0418] 5. The slot where the PDCCH monitoring occasion is located on the cell configured for the multi-slot-based PDCCH monitoring capability meets at least one of the following conditions:

[0419] Based on the multi-slot PDCCH monitoring capability of fixed slot groups, the slot group position is determined according to X and / or O, and the configured PDCCH monitoring occasion is one or more of the following:

[0425] The first span begins at the first slot with PDCCH monitoring configuration at any given time unit, and the maximum length of the span is Y slots. The next span begins at the first slot with PDCCH monitoring configuration but not included in the preceding span, and the maximum length of the span is Y slots. The span pattern repeats every time unit.

[0426] 6. The symbol containing the PDCCH monitoring occasion configured on the cell for the multi-slot-based PDCCH monitoring capability satisfies at least one of the following conditions:

[0429] The PDCCH monitoring occasion symbol is located within a consecutive Y' symbol in the slot;

[0430] The number of symbols for a PDCCH monitoring occasion in a slot does not exceed Y'.

[0431] The PDCCH monitoring capability is defined based on the symbol level span. The span pattern of the symbol granularity is determined according to the symbol where the PDCCH monitoring occasion is located and one of the following rules. The third condition is that the distance between the starting symbols of any consecutive symbol level span is not less than X' symbols:

[0432] For each defined unit of time, the first span begins at the first symbol configured with PDCCH monitoring in that unit of time, and the maximum length of the span is Y' symbols; the next span begins at the first symbol configured with PDCCH monitoring but not included in the preceding span, and the maximum length of the span is Y' symbols.

[0433] The first span begins at the first symbol configured with PDCCH monitoring at any given time unit, and the maximum length of the span is Y' symbols. The next span begins at the first symbol configured with PDCCH monitoring but not included in the preceding span, and the maximum length of the span is Y' symbols. The span pattern repeats every time unit.

[0434] 7. The PDCCH configured on the cell for the multi-slot-based PDCCH monitoring capability meets at least one of the following conditions:

[0435] Based on the multi-slot PDCCH monitoring capability of fixed slot groups, the slot group position is determined according to X and / or O, and the total PDCCH processing parameters (e.g., BD / CCE) of the search space configured for each slot group meet certain conditions.

[0436] Based on the multi-slot PDCCH monitoring capability of slot-granular spans, the slot-granular span pattern is determined according to the slot location of the PDCCH monitoring occasion and one of the following rules. Then, the total PDCCH processing parameters (e.g., BD / CCE) configured in the search space of each span satisfy certain conditions:

[0437] For each defined unit of time, the first span begins at the first slot with PDCCH monitoring configuration in that unit of time, and the maximum length of the span is Y slots; the next span begins at the first slot with PDCCH monitoring configuration but not included in the preceding span, and the maximum length of the span is Y slots.

[0438] The first span begins at the first slot with PDCCH monitoring configuration at any given time unit, and the maximum length of the span is Y slots. The next span begins at the first slot with PDCCH monitoring configuration but not included in the preceding span, and the maximum length of the span is Y slots. The span pattern repeats every time unit.

[0439] 8. The support for multi-slot PDCCH monitoring capability includes at least one of the following limitations (the limitation is either predefined by the protocol or reported by the UE):

[0441] For multi-slot PDCCH monitoring capabilities based on fixed slot groups, consistency includes at least one of the following:

[0442] Multiple neighborhoods have the same X value;

[0443] Multiple cells have the same O value;

[0444] The Y-values ​​of multiple communities are the same.

[0445] For multi-slot PDCCH monitoring capabilities based on slot-granular spans, consistency includes at least one of the following:

[0446] Multiple neighborhoods have the same X value;

[0447] Multiple neighborhoods have the same Y value;

[0448] For cells with the same (X,Y) value, the set of slots containing all PDCCH monitoring occasions in these cells still follows the (X,Y) constraint, and any span pair is within Y symbol slots.

[0449] b) Multiple cells based on multi-timeslot PDCCH monitoring capabilities exhibit consistency:

[0450] For cells with the same SCS, refer to a.

[0451] For different cells in an SCS, consistency must include at least one of the following:

[0452] For a cell with an SCS of μ1 based on multi-slot PDCCH monitoring capability, all its configured PDCCH monitoring occasions are mapped to the frame structure with an SCS of μ2, which is consistent with the UE's reported multi-slot PDCCH monitoring capability based on an SCS of μ2.

[0453] The X value of cells with SCS of μ1 and SCS of μ1 meet certain conditions, such as X1 / μ1 = X2 / μ2;

[0454] The O value of cells with SCS of μ1 and SCS of μ1 meet certain conditions, for example, O1 / μ1=O2 / μ2;

[0455] The Y value of cells with SCS of μ1 and SCS of μ1 meet certain conditions, such as Y1 / μ1=Y2 / μ2.

[0456] 9. The capability to support hybrid PDCCH monitoring includes at least one of the following limitations (the limitation is either predefined by the protocol or reported by the UE):

[0457] Cells based on multi-slot PDCCH monitoring capabilities and cells based on symbol-level span / slot PDCCH monitoring capabilities have consistency and are convertible:

[0458] For a cell with an SCS of μ based on multi-slot PDCCH monitoring capability, all its configured PDCCH monitoring occasions are mapped to the frame structure with an SCS of μ', which conforms to the PDCCH monitoring capability reported by the UE based on symbol-level span / slot with an SCS of μ'.

[0459] Cell-based PDCCH monitoring capabilities based on symbol-level spans / time slots and PDCCH monitoring capabilities based on multiple time slots exhibit consistency and convertibility:

[0460] For a cell with an SCS of μ based on symbol-level span / slot PDCCH monitoring capability, all its configured PDCCH monitoring occasions are mapped to the frame structure with an SCS of μ', which is consistent with the UE's reported multi-slot PDCCH monitoring capability based on an SCS of μ.

[0461] Wherein, μ' is predefined (e.g., 960KHz), or μ' = μ / X.

[0462] 10. The first condition includes at least one of the following:

[0463] The PDCCH monitoring occasion restrictions corresponding to the PDCCH monitoring capabilities determined for each cell (e.g., 5 or 6 indicates restrictions for multi-slot PDCCH monitoring capabilities).

[0464] Do multiple cells meet predefined or reporting capability limitations (such as 8 or 9)?

[0465] 11. The second condition includes at least one of the following:

[0466] a) The PDCCH configuration conforms to the PDCCH monitoring and processing parameter limitations corresponding to the PDCCH monitoring capabilities determined for each cell (e.g., 7 is the limitation for multi-slot PDCCH monitoring capabilities);

[0467] b) When the number of cells in a cell set exceeds the corresponding maximum processing cell capacity parameter limit, the cell set must meet one or more corresponding PDCCH monitoring and processing parameter limits:

[0468] 1) When all cells in a cell group use multi-slot PDCCH monitoring capabilities:

[0469] If based on the multi-slot PDCCH monitoring capability of slot groups, then perform any of the following:

[0470] Cells with at least one identical SCS value of μ in X, Y, and O are grouped together. The sum of PDCCH monitoring and processing parameters (e.g., BD / CCE) in each slot of the cell group meets certain restrictions, such as being less than or equal to the target value.

[0471] Cells that satisfy at least one of X, Y, O and SCSμ under certain conditions (e.g., A = X / μ and / or B = Y / μ and / or C = O / μ are the same) are grouped together. The sum of the PDCCH monitoring and processing parameters (e.g., BD / CCE) of the corresponding slot group (X = A*μ) based on a certain SCSμ' (maximum or minimum μ) in the cell group meets certain restrictions.

[0472] Cells that meet certain conditions (X,Y,O) and have an SCS of μ are converted into virtual cells (X',Y',O') and have an SCS of μ'. The converted virtual cells and the unconverted cells are then used to calculate the total cell group limit according to a.

[0473] If the monitoring capability is based on multi-slot PDCCH at the slot level span, then perform any of the following:

[0474] 1-1: Group cells with at least one identical SCS value of μ in X and Y into a group, and ensure that the sum of PDCCH monitoring and processing parameters (e.g., BD / CCE) in each slotspan of the cell group meets certain restrictions;

[0475] 1-1-1: If all cells in the cell group meet the consistency condition, that is, the set of slots where the PDCCH monitoring occasions in the cell group are located still meets the (X,Y) constraint, then the sum of the PDCCH monitoring processing parameters (e.g., BD / CCE) of each slot-level span after the set is performed in the cell group meets certain constraints, such as being less than or equal to the aforementioned target value.

[0476] 1-1-2: Otherwise, the sum of PDCCH monitoring and processing parameters (e.g., BD / CCE) of the combination of slot-level spans from different cells in this cell group meets certain restrictions;

[0477] 1-2: Convert cells that meet certain conditions (X,Y,O) and have an SCS of μ into virtual cells (X',Y',O') and have an SCS of μ'. Then, calculate the total limit of the cell group for the converted virtual cells and the unconverted cells according to a.

[0478] 2) When a portion of the cells in a cell set are based on multi-slot PDCCH monitoring capabilities and another portion are based on symbol-level span or time-slot PDCCH monitoring capabilities.

[0479] Cells with multi-slot PDCCH monitoring capabilities are equivalent to cells with symbol-level span or time slot-based PDCCH monitoring capabilities, and the total limit of PDCCH monitoring capabilities is calculated together with cells with symbol-level span or time slot-based PDCCH monitoring capabilities.

[0480] The equivalent approach is that for a cell with an SCS of μ based on multi-slot PDCCH monitoring capability, all its configured PDCCH monitoring occasions are mapped to a frame structure with an SCS of μ', which conforms to the PDCCH monitoring capability of symbol-level span / slot based on SCS of μ' reported by the UE. The μ' is predefined (e.g., 120KHz), or μ' = μ / X.

[0481] Note: The above is a terminal-side solution. The network-side solution is the same, for example, the network-side device can perform at least one of the following:

[0482] Receive PDCCH monitoring capability information reported by the UE;

[0483] Configure the UE's PDCCH monitoring capability in each cell;

[0484] Configure the search space according to the PDCCH monitoring capabilities.

[0485] It should be noted that the above PDCCH monitoring occasion refers to all or part of the search space configured in the cell or BWP.

[0486] Example 1

[0487] For configurations with multiple cells, such as Figure 4 As shown, the terminal can map all PDCCH monitoring occasions configured as 480K cells (or BWPs) to the frame structure of 120K cells (or BWPs), effectively making these cells (or BWPs) equivalent to 120K virtual cells (or BWPs). The location of the mapped PDCCH monitoring occasion needs to meet the 120K support capability reported by the UE, that is, meet the 120K-based symbol-level span or time slot PDCCH monitoring capability. BD / CCE limit calculation processing is performed according to the PDCCH monitoring capability of the virtual cell.

[0488] It should be noted that, Figure 4For illustrative purposes only, in other embodiments, the terminal may also map the PDCCH monitoring occasions of all cells (or BWPs) with SCS configured to other values ​​(such as 960K) onto the frame structure of a 120K cell (or BWP) to obtain virtual cells of these cells (or BWPs), and then perform BD / CCE limitation calculation processing according to the PDCCH monitoring capability of the virtual cell.

[0489] Optionally, the location restrictions for PDCCH monitoring occasions are defined according to the multi-slot-based PDCCH monitoring capability definition. BD / CCE restriction calculations are performed using the method described above for converting to virtual cells.

[0490] Example 2

[0491] For scenarios with multiple cells, there are PDCCH monitoring capabilities based on multiple time slots, and PDCCH monitoring capabilities based on symbol-level span / time slot.

[0492] Cells with the same PDCCH monitoring capability type are grouped into a cell set, which corresponds to a maximum PDCCH monitoring and processing cell capacity parameter. When the total number of cells in this cell set exceeds this value:

[0493] The PDCCH monitoring capability of multiple time slots is grouped into a group based on the same (X,Y) and SCS of μ. The sum of the PDCCH monitoring processing parameters (e.g., BD / CCE) of each slot group in the cell group meets certain restrictions, such as being less than or equal to the aforementioned target value.

[0494] This application addresses the multi-cell configuration where at least one cell possesses PDCCH monitoring capability based on multiple time slots, and restricts the location and monitoring capability parameters of the PDCCH monitoring occasion using the following method:

[0495] Method 1: Map the PDCCH monitoring capability based on multi-slot and the location of the PDCCH monitoring occasion of a cell with SCS of μ to the frame structure with SCS of μ'. This is equivalent to limiting the location of subsequent PDCCH monitoring occasions and the PDCCH monitoring capability (BD / CCE, etc.) of a virtual cell based on symbol-level span / slot and SCS of μ'.

[0496] Method 2: Group cells with different PDCCH monitoring capabilities into a cell set. Configure the corresponding maximum PDCCH monitoring capability cell capacity parameter for different cell sets under different scenarios. In each cell set, determine whether the maximum PDCCH monitoring capability cell capacity is exceeded. When the limit is exceeded, for cell sets based on multi-slot PDCCH monitoring capability, divide the cells with (X,Y) and SCS that meet certain conditions into a group, and comply with the overall maximum PDCCH monitoring capability limit.

[0497] As can be seen, in this embodiment of the application, the terminal supports PDCCH monitoring capability based on multiple time slots, that is, the terminal can define PDCCH monitoring capability based on the granularity of multiple time slots. In this way, when using the multi-time slot PDCCH monitoring capability to monitor the PDCCH monitoring capability of multiple cells of the terminal, the complexity of terminal monitoring can be reduced.

[0498] It should be noted that the PDCCH monitoring method provided in this application embodiment can be executed by a PDCCH monitoring device, or by a control module within the PDCCH monitoring device for executing the PDCCH monitoring method. This application embodiment uses the execution of the PDCCH monitoring method by a PDCCH monitoring device as an example to illustrate the PDCCH monitoring device provided in this application embodiment.

[0499] like Figure 5 As shown, the PDCCH monitoring device 500 includes:
