[0019] For ease of understanding, the following describes the contents related to the embodiments of the present application.

[0020] I. First definition of PDCCH monitoring capability PDCCH monitoring capabilities are divided into mandatory capabilities and optional capabilities.

[0021] First, the mandatory capabilities without signaling are as follows: Control resource set (Coreset): In each bandwidth part (BWP) of each cell, one additional Coreset can be configured based on Coreset 0. The additional Coreset satisfies the following: 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 Common search space (CSS) of type 0 / 0A / 2 and Type 1 CSS configured in 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 and UE-specific search space (USS) configured in dedicated RRC, 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) bundle size: 2 / 3 / 6; Interleaved and non-interleaved CCE to REG mapping REG mapping; support for setting precoder granularity size to REG bundle size; support for Dedicated demodulation reference signals (DM-RS) scrambling; support for setting one or more Transmission Configuration Indicator (TCI) states.

[0022] Unicast PDCCH transmission in CSS and USS satisfies the following: The aggregation level (AL) is 1, 2, 4, 8 or 16; for a scheduled secondary cell (Scell), there are a maximum of three search space (SS) sets in each slot of each BWP, and this limit is before SS dropping; for Type 1 and Type 3 CSS and USS configured in dedicated RRC, the monitoring occasions are in the previous three symbols of a slot; for Type 0 / 0A / 2 CSS (Type 0 / 0A / 2-PDCCH CSS set) and Type 1 CSS configured in non-dedicated RRC, the monitoring occasions may be in any one symbol of a slot and within a single span of a slot, where a single span may be understood as three consecutive Orthogonal frequency division multiplex (OFDM) symbols; Downlink Control Information (DCI) formats supporting monitoring include 0_0, 0_1, 1_0 and 1_1; For a Frequency Division Duplex (FDD) system, for each scheduled Component Carrier (CC), each slot handles only one scheduled downlink (DL) unicast transmitted DCI and one scheduled uplink (UL) unicast transmitted DCI; In the case of a Time Division Duplex (TDD) system, for each scheduled CC, each slot handles only one scheduled DL unicast transmitted DCI and two scheduled UL unicast transmitted DCI.

[0023] Next, the mandatory capabilities in the case of signaling are as follows: The Coreset in FR2 satisfies the following: For Type 1 and Type 3 CSS and USS configured by dedicated RRC, the frequency domain is configured based on a bitmap of 6 RBs, and the time domain width can support the configuration of 3 symbols.

[0024] Finally, the optional abilities are: A single PDCCH monitoring opportunity (pdcchMonitoringSingleOccasion) satisfies the following: For FR1, indicates that the UE supports reception of PDCCH scrambled by the Cell Radio Network Temporary Identifier (C-RNTI) and the Configured Scheduling Radio Network Temporary Identifier (CS-RNTI) in any three consecutive symbols of one 15 KHz slot; Any PDCCH monitoring occasions (pdcch-MonitoringAnyOccasions) satisfy the following: In the case of a gap without DCI (withoutDCI-gap), in the CSS and USS of Type 1 and Type 3 configured by the dedicated RRC, the monitoring occasions are in any one symbol of one slot and satisfy the blind decoding (BD) budget restriction; in the case of a DCI gap (withDCI-gap), in the CSS and USS of Type 1 and Type 3 configured by the dedicated RRC, the monitoring occasions are in any one symbol of one slot, but between any two consecutive PDCCHs scrambled by C-RNTI, Modulation and coding scheme (MCS)-C-RNTI, or CS-RNTI, the gap restriction and the BD budget restriction must be satisfied, where the gap restriction includes two symbols of 15KHz, four symbols of 30KHz, seven symbols of 30KHz or Network Core Protocol (NCP), and 14 symbols of 120KHz.

[0025] The PDCCH monitors any situation with a span gap (pdcch-MonitoringAnyOccasionsWithSpanGap), and determines a span pattern based on the (X, Y) values ​​reported by the UE in the Monitoring occasions of all SSs, where the span pattern of each slot is the same, the start position of the first span of the span pattern is the position of the first monitoring occasion of any slot, the length of the span is max{X1, Y1}, the length of the last span may be shorter, and the start position of the next span is the first position of the monitoring occasion that is not included in the previous span, where X1 represents the maximum value of all CORESET durations, and Y1 represents the minimum value of Y in the UE reported candidate value; Check if the span pattern satisfies at least one of the reported (X,Y) constraints.

[0026] II. Second definition of PDCCH monitoring capability As described below, all PDCCH monitoring capabilities are optional capabilities.

[0027] PDCCH monitoring (pdcch-Monitoring) can report supported span values ​​per physical downlink shared channel (PDSCH) processing type and subcarrier space, where each span satisfies the corresponding BD / CCE restrictions. Mixed PDCCH monitoring (pdcch-MonitoringMixed) supports different serving cells having different PDCCH monitoring capability configurations. In carrier aggregation PDCCH monitoring (pdcch-MonitoringCA), the UE reports PDCCH monitoring (UE report pdcch-Monitoring), sets the maximum number of monitoring cells when performing per span BD and CCE restrictions, and at the same time indicates whether the supported span arrangements are aligned or not.

[0028] 3. Terminal mixed PDCCH monitoring capability processing NR Rel-16 has two cell types: Cell Type 1 (FR1 / FR2): Set to slot-based PDCCH monitoring capability. Cell Type 2 (FR1 only): Set to span-based PDCCH monitoring capability.

[0029] NR Rel-16 UEs may experience the following configuration cases: Case 1: All configured scheduling cells belong to cell Type 1. Case 2: All configured scheduling cells belong to cell Type 2. Case 3: At least one scheduling cell belongs to Cell Type 1 and at least one scheduling cell belongs to Cell Type 2.

[0030] For the maximum processing capability parameter, the UE reports each supported case separately, and at the same time, for each case, all cells are grouped according to different PDCCH processing capabilities and the maximum processing capability parameter is reported separately.

[0031] II. Second definition of PDCCH monitoring capability The UE supports PDCCH monitoring capability based on (Xs, Ys) multiple timeslots on a 480K / 960KHz cell or BWP. A timeslot group includes Xs timeslots, each timeslot group is non-overlapping and consecutive. Ys slots are in a timeslot group, and the positions of the Ys slots in each timeslot group are the same. For Type1-PDCCH CSS set provided by dedicated higher layer signaling, Type3-PDCCH CSS sets, and USS sets, these monitor occasions are restricted to within Ys slots in a timeslot group. For Type0 / 0A / 2-PDCCH CSS set and Type1-PDCCH CSS set provided in SIB1, these monitor occasions may be in any slot of a timeslot group.

[0032] Regarding the symbol positions that can be monitored for each slot: If Y>1 (480KHz and 960KHz), the required capability is that the UE needs to monitor only the previous three symbols. If Y=1 (960KHz), the required capability is that the span within one slot of the UE satisfies the (7,3) restriction. If Y=1 (480KHz), the required capability is that the span within one slot of the UE satisfies the (4,3) and (7,3) restrictions, and the maximum number of spans within one slot is 2.

[0033] Regarding BD / CCE restrictions, all search spaces are defined at the granularity of time slot groups.

[0034] Regarding the values ​​of Xs and Ys: If the Subcarrier Spacing (SCS) is 480KHz, then (4,1) is the mandatory value and (4,2) is the optional value. If the SCS is 960KHz, then (8,1) is the mandatory value and (8,4), (4,2) and (4,1) are optional values.

[0035] Hereinafter, the PDCCH monitoring method provided in the embodiments of the present application will be described in detail with reference to the drawings according to several embodiments and their application scenarios.

[0036] Referring to FIG. 2, the PDCCH monitoring method provided in the embodiment of the present application includes: Step 201, in which the terminal determines N1 first scheduling cells, the N1 first scheduling cells being scheduling cells having a PDCCH monitoring capability based on a time slot group among serving cells configured by the terminal; Step 202, in which the terminal determines a target value corresponding to each of the first scheduling cells based on at least one composite value supported by the terminal and a search space corresponding to the N1 first scheduling cells; Step 203, in which the terminal monitors a PDCCH according to target information corresponding to each of the first scheduling cells; where N1 is a positive integer, the target information includes the target value, the composite value includes a first value and a second value, the first value represents the number of time slots included in a non-overlapping, consecutive time slot group, the second value represents the number of time slots that a preset search space can set and monitor within the time slot group, and the target value is one of the composite values ​​or a first value included in one composite value.

[0037] In the embodiment of the present application, the serving cell configured by the terminal includes multiple serving cells, and at least some of the multiple serving cells may be scheduling cells, for example, the serving cell configured by the terminal includes multiple serving cells, including a total of N scheduling cells, where N is a positive integer, and the N scheduling cells can schedule all the serving cells configured by the terminal. The scheduling cell can perform self-scheduling and / or cross-carrier scheduling, where self-scheduling can be understood as cell A scheduling cell A, and cross-carrier scheduling can be understood as cell A scheduling cell B.

[0038] The above N scheduling cells may include N1 first scheduling cells, and may further include N2 second scheduling cells, which are scheduling cells excluding the first scheduling cell among the serving cells configured by the terminal, and may include, for example, a scheduling cell having a PDCCH monitoring capability based on a single timeslot and a scheduling cell having a PDCCH monitoring capability based on a symbol level span.

[0039] Optionally, a parameter related to a PDCCH monitoring capability based on a timeslot group supported by the terminal may be reported or predefined by the terminal, and the parameter related to a PDCCH monitoring capability based on the timeslot group includes at least one composite value as above, where the first value can be represented as Xs and the second value can be represented as Ys, in which case the composite value can be represented as (Xs, Ys).

[0040] The terminal may select a target value corresponding to each of the first scheduling cells from at least one composite value supported according to a search space corresponding to the N1 first scheduling cells, where the target values ​​corresponding to different first scheduling cells may be the same or different, and the target values ​​corresponding to some first scheduling cells may be the same. The target value may include only a first value, or may include a first value and a second value, and the first value included in the determined target value may be represented as Xs0, and the second value included in the determined target value may be represented as Ys0, in which case the target value may be represented as Xs0 or (Xs0, Ys0).

[0041] After determining the target value corresponding to each of the first scheduling cells, PDCCH monitoring of the first scheduling cells can be performed based on the target value corresponding to the first scheduling cells.

[0042] In the embodiment of the present application, a target value corresponding to each of the first scheduling cells is determined according to at least one composite value supported by the terminal and a search space corresponding to the N1 first scheduling cells, and PDCCH monitoring is performed according to the target information corresponding to each of the first scheduling cells having PDCCH monitoring capability based on a time slot group, so that PDCCH monitoring can be realized when the terminal configures multiple serving cells. At the same time, when the terminal supports at least two composite values, there may be different target values ​​for different first scheduling cells, so that the flexibility of PDCCH monitoring can be improved.

[0043] Optionally, in some embodiments, before the step of the terminal determining the N1 first scheduling cells, the method further comprises: The terminal further includes determining a PDCCH monitoring capability type of each scheduling cell among serving cells configured by the terminal according to target indication information transmitted from a network side device; The PDCCH monitoring capability type is for determining the N1 primary scheduling cells.

[0044] It should be understood that the network side equipment can indicate the PDCCH monitoring capability type of each scheduling cell implicitly or explicitly by the target indication information. For example, in some embodiments, the target indication information can be: A PDCCH monitoring capability of each serving cell configured by the terminal; A subcarrier spacing of each serving cell set by the terminal; A PDCCH monitoring capability on the active bandwidth portion BWP of each serving cell configured by the terminal; and the subcarrier spacing on the active BWP of each serving cell configured by the terminal.

[0045] In the embodiment of the present application, when the target indication information indicates the PDCCH monitoring capability of each serving cell set by the terminal or the PDCCH monitoring capability on the active bandwidth portion BWP of each serving cell set by the terminal, it can be specifically indicated by the indication information of the PDCCH monitoring capability, for example, a capability indication value can indicate the PDCCH monitoring capability based on a timeslot group, and another capability indication value can indicate the PDCCH monitoring capability based on a single timeslot. If the target indication information does not include any capability indication value, it defaults to a specific PDCCH monitoring capability, for example, the PDCCH monitoring capability based on a single timeslot. If the target indication information indicates the subcarrier spacing of each serving cell set by the terminal or the subcarrier spacing on the active BWP of each serving cell set by the terminal, the terminal can determine the PDCCH monitoring capability of each serving cell according to the corresponding relationship between the subcarrier spacing and the PDCCH monitoring capability. For example, when the terminal runs or operates on the active BWP of a serving cell of 480K / 960K, it defaults to the PDCCH monitoring capability based on a multi-timeslot group.

[0046] Optionally, in some embodiments, the target value corresponding to the first scheduling cell is: a first value included in the target value is a maximum or minimum first value included in the at least one composite value; if the first values ​​of the at least one composite value are all the same, the first value included in the target value is the first value included in one of the composite values; If the number of the composite values ​​is 1, the target value is the composite value; if the number of the composite values ​​is greater than 1, selecting the target value from a target set according to a preset rule; The target set includes corresponding composite values ​​when a search space configuration of a serving cell or an active BWP of a serving cell satisfies a first preset condition.

[0047] In the embodiment of the present application, when the Xs of the multiple (Xs, Ys) values ​​supported by the terminal are the same, Xs0 is the Xs value. When the terminal supports multiple (Xs, Ys) values, a target set can be determined according to a first condition, and the time slot group determined according to the composite values ​​in the target set can all make the search meet the first preset condition, that is, the above target set can be understood as all composite values ​​among the multiple composite values ​​supported by the terminal that can make the search meet the first preset condition.

[0048] Optionally, in some embodiments, the preset rules include: Rule 1: Select the largest first value included in the target set as the first value of the target value; Rule 2, selecting a maximum first value associated with a target object in the target set as the first value of the target value, the target object including at least one of blind decoding and control channel elements; Rule 3: determining L1 composite values ​​corresponding to the largest first values ​​in the target set, and selecting as the target value the composite value from the L1 composite values ​​whose second values ​​are smallest; and rule 4 for determining L2 composite values ​​corresponding to the largest first values ​​associated with the target object in the target set, and selecting as the target value the composite value from the L2 composite values ​​whose second value is the smallest.

[0049] In the embodiment of the present application, rules 1 and 2 can be understood as having a target value of Xs0, and rules 3 and 4 can be understood as having a target value of a composite value.

[0050] Optionally, rule 3 can be understood as first selecting (Xs, Ys) with the largest Xs from the target set to obtain a first intermediate set, and then selecting (Xs, Ys) with the smallest Yx from the first intermediate set to determine it as (Xs0, Ys0). The first intermediate set includes L1 composite values, and the first value of each of the L1 composite values ​​is the largest Xs.

[0051] Optionally, rule 4 can be understood as first selecting a composite value (Xs, Ys) corresponding to the maximum first value associated with the target object from the target set to obtain a second intermediate set, and then selecting (Xs, Ys) from the second intermediate set with the minimum Yx to determine as (Xs0, Ys0). The second intermediate set includes L2 composite values, and the first values ​​of each of the L2 composite values ​​are all maximum Xs.

[0052] Optionally, in some embodiments, a monitoring rule for the terminal to perform PDCCH monitoring according to target information corresponding to each of the first scheduling cells is: The terminal performs PDCCH monitoring in each first scheduling cell according to a target object restriction corresponding to the first scheduling cell; Grouping the N1 first scheduling cells according to the target information such that each group satisfies a total target target restriction, and performing PDCCH monitoring under the total target target restriction; The target object includes at least one of blind decoding and control channel elements.

[0053] Optionally, the above total target restriction is performed when M or a1*M1+a2*M2 is greater than a corresponding cell capacity parameter, where the cell capacity parameter Ncellcap is related to a combination of PDCCH monitoring capability types corresponding to serving cells configured by the terminal, where M1 is the number of serving cells scheduled by a scheduling cell in which CoresetPoolIndex is not configured or in which CoresetPoolIndex is configured but contains only one index value, and M2 is the number of serving cells scheduled by a scheduling cell in which CoresetPoolIndex is configured and contains multiple index values, and a1 and a2 are values ​​predefined by a protocol, reported by the UE, or configured by the base station.

[0054] Optionally, for each serving cell scheduled by the first scheduling cell, a target target restriction corresponding to the first scheduling cell is: When the first scheduling cell is not configured with a core set pool index (CoresetPoolIndex) or the first scheduling cell includes only one core set pool index value, the terminal does not want the number of candidate PDCCHs (PDCCH candidates) or blind decodings monitored on the target time slot group to exceed a first preset value; and Restriction condition 2, in which the terminal does not want the number of non-overlapping control channel elements monitored on the target time slot group to exceed a second preset value when the first scheduling cell is not configured with a core set pool index or the first scheduling cell includes only one core set pool index value; Restriction condition 3, when the first scheduling cell includes at least two core set pool index values, the terminal does not want the number of candidate PDCCHs or blind decodings corresponding to the same core set pool index monitored on the target time slot group to exceed a first preset value; Restriction condition 4, in which the terminal does not want the number of non-overlapping control channel elements corresponding to the same core set pool index monitored on the target time slot group to exceed a second preset value when the first scheduling cell includes at least two core set pool index values; Restriction condition 5, when the first scheduling cell includes at least two core set pool index values, the terminal does not want the number of candidate PDCCHs or blind decodings monitored on the target time slot group to exceed R times the first preset value (R is a positive integer); and a restriction condition 6 in which, when the first scheduling cell includes at least two core set pool index values, the terminal does not want the number of non-overlapping control channel elements monitored on the target time slot group to exceed R times the second preset value, and the core set pool index set in the first scheduling cell includes at least two index values; The target time slot group is any time slot group including Xs0 time slots on an active BWP of the first scheduling cell, where Xs0 is a first value included in the target value.

[0055] In an embodiment of the present application, the above restriction condition 1 and restriction condition 2 can be understood as meaning that, for each serving cell to be scheduled, the terminal does not want to monitor Bmax PDCCH candidates / BDs or Cmax non-overlapping CCEs on each timeslot group including Xs0 timeslots on the active BWP of the scheduling cell, and CoresetPoolIndex is not set for the scheduling cell or CoresetPoolIndex is set but includes only one index value, where Bmax is the above first preset value and Cmax is the above second preset value.

[0078] In order to better understand the present application, the present invention will be described in detail below with reference to some examples.

[0079] Example 1 The PDCCH monitoring capability information reported by the UE includes: For 480KHz multi-timeslot PDCCH monitoring capability, (Xs, Ys)=(4,1), (4,2) are supported. For 960KHz multi-timeslot PDCCH monitoring capability, (Xs, Ys)=(8,1),(8,4),(4,2),(4,1) are supported.

[0080] The UE configures six serving cells, among which: Cell#0 is a primary serving cell (Pcell), the SCS of its active BWP is 120KHz, it performs self-scheduling, and has the ability to monitor PDCCH based on timeslots. Cell#1 is an Scell, the SCS of its active BWP is 480 KHz, and it is cross-carrier scheduled by the Pcell. Cell#2 is an Scell, the SCS of its active BWP is 480 KHz, it performs self-scheduling, and has the PDCCH monitoring capability based on multiple timeslots. Cell#3 is an Scell, the SCS of its active BWP is 960 KHz, it performs self-scheduling, and has the PDCCH monitoring capability based on multiple timeslots. Cell#4 is an Scell, the SCS of its active BWP is 960 KHz, it performs self-scheduling, and has the PDCCH monitoring capability based on multiple timeslots. Cell#5 is an Scell, the SCS of its active BWP is 960 KHz, and is cross-carrier scheduled by Cell#4. In this case, N=4, the N scheduling cells include Cell#0, 2, 3, 4; N1=3, the N1 scheduling cells include Cell#2, 3, 4; M=4, the M serving cells include Cell#2, 3, 4, 5.

[0082] When Xs takes the maximum value and Ys takes the minimum value, Xs0 and / or Ys0 are obtained, i.e. Cell#2:(4,1); Cell#3:(8,1); Cell#4:(4,2).

[0083] On Cell#2, Cell#3, and Cell#4, the terminals satisfy the BD / CCE restrictions corresponding to the determined (Xs0, Ys0), respectively.

[0084] First, the scheduling cells are classified according to their PDCCH monitoring capability types, that is, Cell#0 is classified as the first class, and Cell#2, 3, and 4 are classified as the second class.

[0085] In the scenario where time slot and multi-time slot are mixed, the cell capacity parameter corresponding to the PDCCH monitoring capability based on multi-time slot is 2. Since M=4>2, it is necessary to group the scheduling cells so that each group complies with the total BD / CCE limit. For example, if SCS and (Xs0, Ys0) are the same, they are grouped together, and Cell#2, 3, and 4 are each in their own group. In the group of Cell#4, T1=2.

[0086] Example 2 The PDCCH monitoring capability information reported by the UE includes: For 480KHz multi-timeslot PDCCH monitoring capability, (Xs, Ys)=(4,1), (4,2) are supported. For 960KHz multi-timeslot PDCCH monitoring capability, (Xs, Ys)=(8,1),(8,4),(4,2),(4,1) are supported.

[0087] The UE configures six serving cells, among which: Cell#0 is a Pcell, the SCS of its active BWP is 120KHz, it performs self-scheduling, and has the ability to monitor PDCCH based on timeslot. Cell#1 is an Scell, the SCS of its active BWP is 480 KHz, and it is cross-carrier scheduled by the Pcell. Cell#2 is an Scell, the SCS of its active BWP is 480 KHz, it performs self-scheduling, and has the PDCCH monitoring capability based on multiple timeslots. Cell#3 is an Scell, the SCS of its active BWP is 960 KHz, it performs self-scheduling, and has the PDCCH monitoring capability based on multiple timeslots. Cell#4 is an Scell, the SCS of its active BWP is 960 KHz, it performs self-scheduling, and has the PDCCH monitoring capability based on multiple timeslots. Cell#5 is an Scell, the SCS of its active BWP is 960 KHz, and is cross-carrier scheduled by Cell#4. In this case, N=4, the N scheduling cells include Cell#0, 2, 3, 4; N1=3, the N1 scheduling cells include Cell#2, 3, 4; M=4, the M serving cells include Cell#2, 3, 4, 5.

[0088] The (Xs, Ys) values ​​that satisfy the first condition determined based on the search space configuration on the N1 scheduling cells include: Cell#2:(4,1),(4,2); Cell#3:(8,1),(8,4),(4,1),(4,2); Cell#4:(4,2).

[0089] When Xs takes the maximum value and Ys takes the minimum value, Xs0 and / or Ys0 are obtained, i.e. Cell#2:(4,1); Cell#3:(8,1); Cell#4:(4,2).

[0090] On Cell#2, Cell#3, and Cell#4, the terminals satisfy the BD / CCE restrictions corresponding to the determined (Xs0, Ys0), respectively.

[0091] Cell#2, Cell#3 and Cell#4 are equated to virtual scheduling cells based on time slots of SCS=120KHz and treated together with Cell#0, i.e. Cell#0,2,3,4 are made the same, and if the number of serving cells scheduled by them exceeds the cell capacity parameter, a total BD / CCE budget restriction is imposed on 120K slots.
