[0030] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0031] I. First definition of PDCCH monitoring capability.

[0032] PDCCH's monitoring capabilities are divided into mandatory and optional capabilities.

[0033] First, the mandatory capabilities (mandatory without capability signaling) that are not specifically for signaling are as follows:

[0034] Control resource set (Coreset): Each bandwidth part (BWP) of each cell can be configured with one additional Coreset on top of Coreset 0; the additional Coreset satisfies the following:

[0035] For Frequency Range (FR) 1: The frequency domain is configured based on a bitmap of 6 Resource Blocks (RBs), and the time domain width can support configuration of 1 to 3 symbols; For FR 2: For Type 1 CSS configured with Type 0 / 0A / 2 Common Search Space (CSS) and non-dedicated Radio Resource Control (RRC), the frequency domain is configured based on a bitmap of 6 RBs, and the time domain width can support configuration of 1 to 3 symbols; For Type 1 and Type 3 CSS configured with dedicated RRC and UE-specific search space (USS), the frequency domain is configured based on a bitmap of 6 RBs, and the time domain width can support configuration of 1 to 2 symbols; Resource Element Group (REG) bundles size: 2 / 3 / 6; Interleaved and non-interleaved CCE to REG mapping. Mapping); supports configuring the precoder granularity size to REG bundlesize; supports scrambling with dedicated demodulation reference signals (DM-RS); supports configuring one or more Transmission Configuration Indicator (TCI) states.

[0036] Unicast PDCCH transmissions in CSS and USS satisfy the following: the aggregation level (AL) is 1, 2, 4, 8, or 16; for scheduled secondary cells (Scells), each BWP has a maximum of 3 search space (SS) sets per slot, and this restriction is in place before SS dropping; for Type 1 and Type 3 CSS and USS with dedicated RRC configurations, monitoring occasions occur within the first 3 symbols of a slot; for Type 0 / 0A / 2 CSS (Type 0 / 0A / 2-PDCCH CSS set) and Type 1 CSS with non-dedicated RRC configurations, monitoring occasions can occur within any 1 symbol of a slot, and within a single span of a slot. A single span can be understood as 3 consecutive orthogonal frequency division multiplex (OFDM) symbols.

[0037] Supported formats for monitoring Downlink Control Information (DCI) include 0_0, 0_1, 1_0, and 1_1;

[0038] For a Frequency Division Duplex (FDD) system, for each scheduled Component Carrier (CC), each slot processes only one DCI scheduled for downlink (DL) unicast transmission and one DCI scheduled for uplink (UL) unicast transmission.

[0039] For a Time Division Duplex (TDD) system, for each scheduled CC, each slot processes only one DCI scheduled for DL ​​unicast transmission and two DCI scheduled for UL unicast transmission.

[0040] Secondly, the mandatory signaling capabilities are as follows:

[0041] The Coreset in FR2 satisfies the following: for Type 1 and Type 3 CSS and USS with dedicated RRC configuration, the frequency domain is configured based on a bitmap of 6 RBs, and the time domain width can support the configuration of 3 symbols.

[0042] Finally, the capabilities of Optional are as follows:

[0043] A single PDCCH monitoring opportunity (pdcchMonitoringSingleOccasion) satisfies the following: For FR1, it indicates that the UE supports receiving PDCCH scrambled with Cell Radio Network Temporary Identifier (C-RNTI) and Configured Scheduling Radio Network Temporary Identifier (CS-RNTI) in any 3 consecutive symbols in a 15kHz slot;

[0044] Any PDCCH monitoring occasions satisfy the following conditions: For those without a DCI gap, for Type 1 and Type 3 CSS and USS with dedicated RRC configurations, monitoring occasions are any one symbol in a slot and comply with the blind decoding (BD) budget. For those with a DCI gap, for Type 1 and Type 3 CSS and USS with dedicated RRC configurations, monitoring occasions are any one symbol in a slot, but any two consecutive PDCCHs scrambled with C-RNTI, Modulation and Coding Scheme (MCS)-C-RNTI, or CS-RNTI must satisfy the gap constraint and the BD budget constraint. The gap constraint includes: 2 symbols at 15 kHz, 4 symbols at 30 kHz, and 30 kHz or Network Core protocol. The protocol (NCP) has 7 symbols, and 14 symbols for 120kHz.

[0045] The PDCCH monitors any instances with span gaps (pdcch-MonitoringAnyOccasionsWithSpanGap). It determines the span pattern based on the (X, Y) values ​​reported by the UE according to the monitoring occasion configuration of all SSs. Each slot has the same span pattern. The first span of the pattern starts at the position of the first monitoring occasion in any slot, with a span length of max{X1,Y1}. The last span may be slightly shorter. The next span starts at the first position of a monitoring occasion not included in the preceding span. Here, X1 represents the maximum value of all CORESET durations, and Y1 represents the minimum value of Y among all candidate Y values ​​reported by the UE.

[0046] Check if the span pattern satisfies at least one reporting (X,Y) constraint.

[0047] II. A second definition of PDCCH monitoring capability.

[0048] All PDCCH monitoring capabilities are optional, as shown below:

[0049] PDCCH monitoring can report the supported span values ​​for each Physical Downlink Shared Channel (PDSCH) processing type and each subcarrier space, and ensure that each span conforms to the corresponding BD / CCE limits.

[0050] Hybrid PDCCH monitoring (pdcch-MonitoringMixed) supports different PDCCH monitoring capabilities for different serving cells.

[0051] Carrier aggregation PDCCH monitoring (pdcch-MonitoringCA), terminal reporting PDCCH monitoring (UE reportpdcch-Monitoring), configure the maximum number of monitoring cells when performing per-span BD and CCE restrictions, and indicate whether the span arrangement is aligned.

[0052] III. Handling of the terminal's hybrid PDCCH monitoring capability.

[0053] For NR Rel-16, there are the following two cell types:

[0054] Cell Type 1 (FR1 / FR2): Configured for slot-based PDCCH monitoring capability;

[0055] Cell Type 2 (FR1 only): Configured for span-based PDCCH monitoring capability.

[0056] For NR Rel-16 UEs, the following configuration cases may occur:

[0057] Case 1: All configured scheduling cells belong to cell type 1;

[0058] Case 2: All configured scheduling cells belong to cell type 2;

[0059] Case 3: At least one scheduled cell belongs to Cell Type 1, and at least one scheduled cell belongs to Cell Type 2.

[0060] For the maximum processing capacity parameter, the UE reports separately for each supported case. Simultaneously, for each case, all cells are grouped according to their different PDCCH processing capabilities, and the maximum processing capacity parameter is reported separately for each group.

[0061] II. A second definition of PDCCH monitoring capability.

[0062] The UE supports multi-slot PDCCH monitoring capabilities based on (Xs, Ys) on 480K / 960KHz cells or BWPs. A slot group contains Xs slots, which are non-overlapping and consecutive. Ys slots are located within each slot group, and the positions of the Ys slots within each slot group are identical. For Type 1 PDCCH CSS sets provided by dedicated higher layer signaling, Type 3 PDCCH CSS sets, and USS sets, these monitoring occasions are restricted to Ys slots within the slot group. For Type 0 / 0A / 2 PDCCH CSS sets and Type 1 PDCCH CSS sets provided in System Information Block (SIB1), these monitoring occasions can occur on any slot within the slot group.

[0063] For each slot, the monitorable symbol positions are as follows: if Y > 1 (480KHz and 960KHz), the mandatory capability is that the UE only needs to monitor the first 3 symbols; if Y = 1 (960KHz), the mandatory capability is that the UE's span within a slot meets the (7,3) constraint; if Y = 1 (480KHz), the mandatory capability is that the UE's span within a slot meets both the (4,3) and (7,3) constraints, and the maximum number of spans within a slot is 2.

[0064] The limitations of BD / CCE are defined at the granularity of time slot groups for all search spaces.

[0065] For the values ​​of Xs and Ys: if the subcarrier spacing (SCS) is 480KHz, (4,1) is the mandatory value and (4,2) is the optional value; if the SCS is 960KHz, (8,1) is the mandatory value and (8,4), (4,2) and (4,1) are the optional values.

[0066] The monitoring method for PDCCH provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0067] Reference Figure 2The PDCCH monitoring method provided in this application includes:

[0068] Step 201: The terminal determines N1 first scheduling cells, wherein the N1 first scheduling cells are the scheduling cells based on the PDCCH monitoring capability of the time slot group among the serving cells configured by the terminal.

[0069] Step 202: The terminal determines the target value corresponding to each of the first scheduling cells based on at least one combination value supported by the terminal and the search space corresponding to the N1 first scheduling cells;

[0070] Step 203: The terminal performs PDCCH monitoring based on the target information corresponding to each of the first scheduling cells;

[0071] Wherein, N1 is a positive integer, the target information includes the target value, the combined value includes a first value and a second value, the first value represents the number of time slots contained in a non-overlapping and consecutive time slot group, the second value represents the number of time slots that can be configured and monitored in the time slot group in the preset search space, and the target value is a combined value or a first value contained in a combined value.

[0072] In this embodiment, the serving cells configured on the terminal include multiple serving cells, at least some of which can be scheduling cells. For example, the serving cells configured on the terminal include a total of N scheduling cells, where N is a positive integer. These N scheduling cells can schedule all the serving cells configured on the terminal. The scheduling cells can perform self-scheduling and / or cross-carrier scheduling. Self-scheduling can be understood as cell A scheduling cell A, and cross-carrier scheduling can be understood as cell A scheduling cell B.

[0073] The aforementioned N scheduling cells may include N1 first scheduling cells, and may further include N2 second scheduling cells. The second scheduling cells are the scheduling cells other than the first scheduling cells among the serving cells configured for the terminal. For example, they may include scheduling cells based on single-slot PDCCH monitoring capability and scheduling cells based on symbol-level span PDCCH monitoring capability.

[0074] Optionally, the terminal may report or predefine PDCCH monitoring capability parameters based on time slot groups supported by the terminal. These parameters may include at least one combination of the above-mentioned values. The first value may be represented as Xs, the second value as Ys, and the combination value may be represented as (Xs, Ys).

[0075] The terminal can select a target value corresponding to each of the N1 first scheduling cells from at least one supported combination of values ​​within the search space corresponding to the first scheduling cells. The target values ​​corresponding to different first scheduling cells can be the same, different, or some first scheduling cells can have the same target value. The target value can include only a first value, or it can include both a first value and a second value. The first value included in the determined target value can be represented as Xs0, and the second value included in the determined target value can be represented as Ys0. Therefore, the target value can be Xs0 or (Xs0, Ys0).

[0076] After determining the target value corresponding to each first scheduling cell, PDCCH monitoring can be performed on the scheduling cell based on the target value corresponding to the first scheduling cell.

[0077] This embodiment of the application determines the target value corresponding to each first scheduling cell based on at least one combination value supported by the terminal and the search space corresponding to the N1 first scheduling cells, and performs PDCCH monitoring according to the target information corresponding to the first scheduling cell with PDCCH monitoring capability based on time slot groups. In this way, PDCCH monitoring can be implemented when the terminal is configured with multiple serving cells. At the same time, when the terminal supports at least two combination values, different target values ​​can exist for different first scheduling cells, thereby improving the flexibility of PDCCH monitoring.

[0078] Optionally, in some embodiments, before the terminal determines N1 first scheduling cells, the method further includes:

[0079] The terminal determines the PDCCH monitoring capability type of each scheduling cell in the serving cell configured by the terminal based on the target indication information sent by the network-side device.

[0080] The PDCCH monitoring capability type is used to determine the N1 first scheduling cells.

[0081] It should be understood that network-side devices can implicitly or explicitly indicate the PDCCH monitoring capability type of each scheduled cell through target indication information. For example, in some embodiments, the target indication information can be used to indicate at least one of the following:

[0082] The terminal is configured with PDCCH monitoring capabilities for each serving cell;

[0083] The subcarrier spacing of each serving cell configured in the terminal;

[0084] The terminal is configured with PDCCH monitoring capability on the active bandwidth portion of the BWP for each serving cell;

[0085] The subcarrier spacing on the active BWP of each serving cell configured in the terminal.

[0086] In this embodiment, when the target indication information indicates the PDCCH monitoring capability of each serving cell configured by the terminal or the PDCCH monitoring capability on the active bandwidth portion (BWP) of each serving cell configured by the terminal, it can be specifically indicated by the indication information of the PDCCH monitoring capability. For example, one capability indication value indicates the PDCCH monitoring capability based on a time slot group, and another capability indication value indicates the PDCCH monitoring capability based on a single time slot. When the target indication information does not include any capability indication value, the default is a specific PDCCH monitoring capability, such as the PDCCH monitoring capability based on a single time slot. When the target indication information indicates the subcarrier spacing of each serving cell configured by the terminal or the subcarrier spacing on the active BWP of each serving cell configured by the terminal, the terminal can determine the PDCCH monitoring capability of each serving cell according to the correspondence between the subcarrier spacing and the PDCCH monitoring capability. For example, when the terminal is running or operating on the active BWP of a 480K / 960K serving cell, the default is the PDCCH monitoring capability based on multiple time slot groups.

[0087] Optionally, in some embodiments, the target value corresponding to the first scheduling cell satisfies at least one of the following:

[0088] The target value includes a first value that is the largest or smallest first value contained in the at least one combined value;

[0089] If the first values ​​in all at least one combination value are the same, the first value included in the target value is the first value included in any combination value;

[0090] When the number of combined values ​​is 1, the target value is the combined value;

[0091] If the number of combined values ​​is greater than 1, the target value is selected from the target set according to a preset rule;

[0092] The target set includes the corresponding combination values ​​when the search space configuration of the serving cell or the serving cell activating BWP meets the first preset condition.

[0093] In this embodiment, if the Xs of multiple (Xs, Ys) values ​​supported by the terminal are the same, then Xs0 is that Xs value. If the terminal supports multiple (Xs, Ys) values, a target set can be determined based on a first condition. The time slot group determined based on the combination values ​​in the target set can make the search satisfy the first preset condition. In other words, the target set can be understood as all the combination values ​​among the multiple combination values ​​supported by the terminal that can make the search satisfy the first preset condition.

[0094] Optionally, in some embodiments, the preset rule includes at least one of the following:

[0095] Rule 1: Select the largest first value contained in the target set as the first value of the target value;

[0096] Rule 2: Select the first value of the largest associated target object in the target set as the first value of the target value, wherein the target object includes at least one of blind detection code and control channel unit;

[0097] Rule 3: Determine the L1 combined values ​​corresponding to the largest first value in the target set, and select the combined value with the smallest second value from the L1 combined values ​​as the target value;

[0098] Rule 4: Determine the L2 combined values ​​corresponding to the largest first value of the associated target object in the target set, and select the combined value with the smallest second value from the L2 combined values ​​as the target value.

[0099] In this embodiment of the application, rule 1 and rule 2 can be understood as the target value being Xs0, and rule 3 and rule 4 can be understood as the target value being a combination value.

[0100] Optionally, rule 3 can be understood as follows: first, select the (Xs, Ys) with the largest Xs from the target set to obtain the first intermediate set; then, select the (Xs, Ys) with the smallest Yx from the first intermediate set to determine (Xs0, Ys0). The first intermediate set includes L1 combination values, and the first value of each of the L1 combination values ​​is the largest Xs.

[0101] Optionally, rule 4 can be understood as follows: first, select the combination value (Xs, Ys) corresponding to the largest first value of the associated target object from the target set to obtain the second intermediate set; then, select the (Xs, Ys) with the smallest Yx from the second intermediate set to determine (Xs0, Ys0). The second intermediate set includes L2 combination values, and the first value of each of the L2 combination values ​​is the largest Xs.

[0102] Optionally, in some embodiments, the monitoring rules for PDCCH monitoring performed by the terminal based on the target information corresponding to each of the first scheduling cells satisfy at least one of the following:

[0103] The terminal performs PDCCH monitoring in each first scheduling cell according to the target object restriction corresponding to the first scheduling cell;

[0104] The N1 first scheduling cells are grouped according to the target information, and each group meets the overall target object limit, and PDCCH monitoring is performed under the overall target object limit.

[0105] The target object includes at least one of a blind detection code and a control channel unit.

[0106] Optionally, the total target object mentioned above is limited to when M or a1*M1+a2*M2 is greater than the corresponding cell capacity parameter. The cell capacity parameter Ncellcap is related to the combination of PDCCH monitoring capability types corresponding to the serving cell configured by the terminal. M1 is the number of serving cells scheduled by the scheduling cell that does not configure CoresetPoolIndex or configures CoresetPoolIndex but only contains one index value; M2 is the number of serving cells scheduled by the scheduling cell that configures CoresetPoolIndex and contains multiple index values; a1 and a2 are values ​​predefined by the protocol, reported by the UE, or configured by the base station.

[0107] Optionally, for each serving cell scheduled by the first scheduling cell, the target object restrictions corresponding to the first scheduling cell include at least one of the following:

[0108] Limitation 1: If the first scheduling cell does not have a CoresetPoolIndex configured or the first scheduling cell contains only one control resource set pool index value, the terminal does not expect the number of candidate PDCCHs or blind detection codes monitored on the target time slot group to exceed the first preset value.

[0109] Restriction 2: If the first scheduling cell is not configured with a resource set pool index or the first scheduling cell contains only one control resource set pool index value, the terminal does not expect the number of non-overlapping control channel elements monitored on the target time slot group to exceed the second preset value.

[0110] Restriction 3: When the first scheduling cell contains at least two control resource set pool index values, the terminal does not expect the number of candidate PDCCHs or blind detection codes corresponding to the same control resource set pool index to be monitored on the target time slot group to exceed the first preset value.

[0111] Restriction 4: When the first scheduling cell contains at least two control resource set pool index values, the terminal does not expect the number of non-overlapping control channel elements corresponding to the same control resource set pool index monitored on the target time slot group to exceed the second preset value.

[0112] Limitation 5: When the first scheduling cell contains at least two control resource set pool index values, the terminal does not expect the number of candidate PDCCHs or blind detection codes monitored on the target time slot group to exceed the first preset value R times, where R is a positive integer.

[0113] Limitation 6: When the first scheduling cell contains at least two control resource set pool index values, the terminal does not expect the number of non-overlapping control channel elements monitored on the target time slot group to exceed the second preset value R times, and the control resource set pool index configured in the first scheduling cell includes at least two index values.

[0114] Wherein, the target time slot group is any one of the time slot groups containing Xs0 time slots on the active BWP of the first scheduling cell, and Xs0 is the first value included in the target value.

[0115] In this embodiment of the application, the above-mentioned restriction conditions 1 and 2 can be understood as follows: For each scheduled serving cell, the terminal does not expect Bmax PDCCH candidates / BDs or Cmax non-overlapping CCEs to be monitored on each time slot group containing Xs0 time slots on the active BWP of the scheduled cell. The scheduled cell does not configure CoresetPoolIndex or configures CoresetPoolIndex but only contains one index value, where Bmax is the above-mentioned first preset value and Cmax is the above-mentioned second preset value.

P1 and Q1 are both positive integers.

[0153] The P1 scheduling cells and the Q1 scheduling cells are grouped according to the subcarrier spacing.

[0154] In this embodiment, the scheduled cells can be grouped according to SCS, and PDCCH monitoring can be performed within each group while meeting the overall BD / CCE limit. Specifically, the overall BD / CCE limit is set when P / a1*P11+a2*P12 or Q / a1*Q11+a2*Q12 is greater than the corresponding cell capacity parameter. The cell capacity parameter Ncellcap is related to the combination of the equivalent PDCCH monitoring capability types of N1 virtual scheduled cells and the PDCCH monitoring capability types of N-N1 scheduled cells.

[0159] The frame or subframe boundaries of all scheduled cells in the serving cell configured in the terminal are aligned.

[0161] To better understand this application, the following examples will be used to illustrate it in detail.

[0162] Example 1:

[0163] The UE reports PDCCH monitoring capability information, including:

[0164] For 480KHz multi-slot PDCCH monitoring capability, it supports (Xs,Ys)=(4,1),(4,2);

[0165] For 960KHz multi-slot PDCCH monitoring capability, it supports (Xs,Ys)=(8,1),(8,4),(4,2),(4,1).

[0166] The UE is configured with 6 serving cells, among which,

[0167] Cell#0 is the primary serving cell (Pcell), with its activated BWP SCS at 120KHz, self-scheduling, and slot-based PDCCH monitoring capability.

[0168] Cell#1 is an Scell, whose activated BWP SCS is 480KHz, and is scheduled across carriers by the Pcell.

[0169] Cell#2 is an Scell ​​with an activation SCS of 480KHz for BWP, self-scheduling, and based on multi-slot PDCCH monitoring capabilities.

[0170] Cell#3 is an S-cell with an activation BWP SCS of 960KHz, self-scheduling, and based on multi-slot PDCCH monitoring capabilities.

[0171] Cell #4 is an S-cell with an activation BWP SCS of 960kHz, self-scheduling, and based on multi-slot PDCCH monitoring capabilities.

[0172] Cell#5 is an Scell, whose activated BWP SCS is 960KHz, and is scheduled across carriers by Cell#4.

[0173] At this point, N=4, and the N scheduled cells include Cell#0,2,3,4; N1=3, and the N1 scheduled cells include Cell#2,3,4; M=4, and the M serving cells include Cell#2,3,4,5.

[0174] The (Xs,Ys) values ​​that satisfy the first condition are determined based on the search space configuration on the N1 scheduling cells:

[0175] Cell#2: (4,1), (4,2);

[0176] Cell#3: (8,1),(8,4),(4,1),(4,2);

[0177] Cell#4: (4,2).

[0178] Xs0 and / or Ys0 are obtained by taking the maximum value of Xs and the minimum value of Ys, that is...

[0179] Cell#2: (4,1);

[0180] Cell#3: (8,1);

[0181] Cell#4: (4,2).

[0182] On Cell#2, Cell#3, and Cell#4, the terminals conform to the BD / CCE constraints corresponding to their respective (Xs0, Ys0) values.

[0183] First, the scheduling cells are classified according to the PDCCH monitoring capability type, with Cell#0 belonging to the first category and Cell#2, 3, and 4 belonging to the second category.

[0184] In mixed time-slot and multi-time-slot scenarios, the cell capacity parameter corresponding to the multi-time-slot PDCCH monitoring capability is 2. Since M = 4 > 2, the scheduled cells need to be grouped, and each group follows the overall BD / CCE limit. For example, according to the same SCS and (Xs0, Ys0) grouping, Cell#2, 3, and 4 are each in one group. For the grouping of Cell#4, T1 = 2.

[0185] Example 2:

[0186] UE reports PDCCH monitoring capability information, including

[0187] For 480KHz multi-slot PDCCH monitoring capability, it supports (Xs,Ys)=(4,1),(4,2);

[0188] For 960KHz multi-slot PDCCH monitoring capability, it supports (Xs,Ys)=(8,1),(8,4),(4,2),(4,1).

[0189] The UE is configured with 6 serving cells, among which,

[0190] Cell#0 is a Pcell with an activation SCS of 120KHz for BWP, self-scheduling, and slot-based PDCCH monitoring capability.

[0191] Cell#1 is an Scell, whose activated BWP SCS is 480KHz, and is scheduled across carriers by the Pcell.

[0192] Cell#2 is an Scell ​​with an activation SCS of 480KHz for BWP, self-scheduling, and based on multi-slot PDCCH monitoring capabilities.

[0193] Cell#3 is an S-cell with an activation BWP SCS of 960KHz, self-scheduling, and based on multi-slot PDCCH monitoring capabilities.

[0194] Cell #4 is an S-cell with an activation BWP SCS of 960kHz, self-scheduling, and based on multi-slot PDCCH monitoring capabilities.

[0195] Cell#5 is an Scell, whose activated BWP SCS is 960KHz, and is scheduled across carriers by Cell#4.

[0196] At this point, N=4, the N scheduled cells include Cell#0,2,3,4; N1=3, the N1 scheduled cells include Cell#2,3,4; M=4, the M serving cells include Cell#2,3,4,5.

[0197] The (Xs,Ys) values ​​that satisfy the first condition are determined based on the search space configuration on the N1 scheduling cells:

[0198] Cell#2: (4,1), (4,2);

[0199] Cell#3: (8,1),(8,4),(4,1),(4,2);

[0200] Cell#4: (4,2).

[0201] Xs0 and / or Ys0 are obtained by taking the maximum value of Xs and the minimum value of Ys, that is...

[0202] Cell#2: (4,1);

[0203] Cell#3: (8,1);

[0204] Cell#4: (4,2).

[0205] On Cell#2, Cell#3, and Cell#4, the terminals conform to the BD / CCE constraints corresponding to their respective (Xs0, Ys0) values.

[0206] Cell#2, Cell#3, and Cell#4 are equivalent to slot-based virtual scheduling cells with SCS=120KHz, and are processed together with Cell#0. That is, Cell#0,2,3,4 are in one class, and when the number of serving cells they schedule exceeds the cell capacity parameter, the total BD / CCE budget is limited according to 120K slots.
