[0045] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0046] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0047] I. New Radio (NR) Rel-15 Physical Downlink Control Channel (PDCCH) monitoring capability.

[0048] In NR Rel-15, the monitoring capabilities of PDCCH can be divided into mandatory and optional capabilities.

[0049] The capability to force a mandatory signal without capability is as follows:

[0050] 1) Control Resource Set (CORESET): Each BandWidth Part (BWP) of each cell can be configured with one additional CORESET on top of CORESET 0.

[0051] FR1: Bitmap of 6 Radio Bearer (RB) + 1 to 3 symbols.

[0052] FR2: For Type 0, 0A, 2 Common Search Space (CSS) and non-dedicated Radio Resource Control (RRC) configurations, Type 1, 6RB bitmap + 1 to 3 symbols; For Type 1, Type 3 and UE specific Search Space (USS) configurations with dedicated RRC, 6RB bitmap + 1 to 2 symbols.

[0053] Resource unit bundle size (REG bundle size): 2 / 3 / 6.

[0054] Interleaved and non-interleaved control channel element to resource element group mapping (CCE to REG mapping).

[0055] It supports configuring the precoder granularity size to the REG bundle size.

[0056] Supports scrambling with dedicated demodulation reference signals (DM-RS).

[0057] It supports configuring one or more Transport Configuration Indicator (TCI) states.

[0058] 2) Unicast PDCCH transmission in CSS and USS.

[0059] Aggregation Level (AL) 1, 2, 4, 8, 16.

[0060] 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.

[0061] For Type 1, Type 3, and USS with dedicated RRC configurations, monitoring occasions occur in the first three symbols of a slot.

[0062] For Type 0, 0A, 2 CSS and Type 1 with non-dedicated RRC configuration, 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).

[0063] 3) Supports monitoring downlink control information (DCI) 0_0, 0_1, 1_0, 1_1.

[0064] 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.

[0065] 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.

[0066] The capabilities of mandatory signaling are as follows:

[0067] CORESET in FR2.

[0068] For Type 1, Type 3, and USS with dedicated RRC configurations, the bitmap of 6RB is plus 3 symbols.

[0069] The capabilities of Optional are as follows:

[0070] 1) pdcchMonitoringSingleOccasion.

[0071] 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).

[0072] 2) pdcch-MonitoringAnyOccasions.

[0073] withoutDCI-gap: For Type 1, Type 3 and USS with dedicated RRC configurations, monitoring occurrences are any one symbol in a slot and are subject to blind decoding (BD) budget constraints.

[0074] 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 15 kHz, 4 symbols for 30 kHz, 7 symbols for (60 kHz, NCP) and 14 symbols for 120 kHz, while also complying with BD budget constraints.

[0075] 3) pdcch-MonitoringAnyOccasionsWithSpanGap.

[0076] The span pattern is determined based on the (X, Y) values ​​of the UE reporting configured for all SS monitoring occasions.

[0077] The span pattern is the same for each slot.

[0078] 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.

[0079] Check if the span pattern satisfies at least one (X, Y) constraint of the reporting.

[0080] II. PDCCH monitoring capability of NR Rel-16.

[0081] In NR Rel-16, all PDCCH monitoring capabilities are optional, as shown below:

[0082] 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.

[0083] pdcch-MonitoringMixed-r16: Supports different PDCCH monitoring capability configurations for different serving cells.

[0084] 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.

[0085] The embodiments of this application will be described in detail below with reference to the accompanying drawings and through some examples and application scenarios.

[0086] 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:

[0087] Step 201: The terminal receives first information, which includes at least one of the following: search space configuration; PDCCH monitoring capability configuration.

[0088] 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 corresponding to each search space group through PDCCH monitoring capability configuration. The PDCCH monitoring capability corresponding to a certain search space group can be understood as: the terminal's PDCCH monitoring capability in that search space group.

[0089] Step 202: The terminal determines the PDCCH monitoring capabilities corresponding to the R search space groups of the terminal based on the first information, where R is a positive integer.

[0090] In a specific implementation, if the first information includes the PDCCH monitoring capability configuration, the PDCCH monitoring capabilities corresponding to the R search space groups can be determined based on the PDCCH monitoring capability configuration.

[0091] If the first information does not include the PDCCH monitoring capability configuration, the PDCCH monitoring capabilities corresponding to the R search space groups can be predefined by the protocol.

[0092] All search spaces of the terminal correspond to the R search space groups. Specifically, each of the R search space groups can include some or all of the terminal's search spaces, and at least one search space in each of the R search space groups is different. The search spaces included in each search space group can be predefined by the protocol or configured by the network-side device.

[0093] Each of the R search space groups can correspond to at least one search space type, and the search space types corresponding to different search space groups can be different or the same. The search space types can include CSS and USS. Furthermore, CSS can be further divided into at least one of the following: Type 0, 0A, 2 CSS and Type 1 CSS with non-dedicated RRC configuration; USS can be further divided into: Type 1, Type 3 and USS with dedicated RRC configuration.

[0094] Optionally, the PDCCH monitoring capabilities corresponding to the R search space groups may include at least one of the following:

[0095] Based on multi-timeslot PDCCH monitoring capability, that is, PDCCH monitoring capability can be defined based on the granularity of multi-timeslot;

[0096] Slot-based PDCCH monitoring capability, meaning that PDCCH monitoring capability can be defined based on the granularity of a single slot;

[0097] PDCCH monitoring capability based on symbol-level span means that PDCCH monitoring capability can be defined based on the granularity of symbol-level span.

[0098] It is understood that the PDCCH monitoring capabilities corresponding to the R search space groups are all PDCCH monitoring capabilities supported by the terminal; the PDCCH monitoring capabilities corresponding to the N R search space groups can be the same or different, depending on the actual situation, and this application embodiment does not limit this. One search space group corresponds to one PDCCH monitoring capability, and for a certain search space group, all search spaces in that search space group correspond to that PDCCH monitoring capability.

[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 203: The terminal monitors the PDCCH of the N cell groups of the terminal according to the PDCCH monitoring capabilities corresponding to the R search space groups respectively.

[0104] All cells of the terminal correspond to the N cell groups, specifically: each of the N cell groups may include some or all of the cells of the terminal, and at least one cell in each cell group is different. The cells included in each cell group may be predefined by the protocol or configured by the network-side equipment.

[0105] The N cell groups can be configured with at least one of the R search space groups. The search space groups configured for different cell groups can be the same or different, depending on the actual situation. This application embodiment does not limit this.

[0106] In practice, for each cell group, the PDCCH of that cell group can be monitored based on the PDCCH monitoring capability corresponding to the search space group configured for that cell group.

[0107] The PDCCH monitoring method of this application allows a terminal to correspond to R search space combinations and N cell groups. The terminal can determine the PDCCH monitoring capabilities corresponding to each of the R search space groups to monitor the PDCCH of the terminal's N cell groups. Therefore, this application can define various types of PDCCH monitoring capabilities at the granularity of search space groups, thereby improving the flexibility of search space configuration.

[0108] In this embodiment of the application, the N cell groups may optionally include at least one of the following:

[0109] The first cell group, which includes all serving cells or dispatching cells;

[0110] The second cell group consists of only a single serving cell or a single dispatch cell;

[0111] The third cell group, wherein the cells included in the third cell group satisfy the first condition.

[0112] Optionally, the first condition includes at least one of the following:

[0113] The cell is a dispatch cell;

[0114] The subcarrier spacing (SCS) of the cells is the same;

[0115] The PDCCH monitoring capabilities of the corresponding cells are the same;

[0116] Cells belong to the same cell group in dual connectivity (DC), such as the Master Cell Group (MCG) or the Secondary Cell Group (SCG).

[0117] It should be noted that, in one implementation, cells with PDCCH monitoring capabilities based on time slot groups and cells supporting PDCCH monitoring capabilities based on time slot spans can be considered to have the same PDCCH monitoring capability. In another implementation, cells with PDCCH monitoring capabilities based on time slot groups and cells supporting PDCCH monitoring capabilities based on time slot spans can be considered to have different PDCCH monitoring capabilities.

[0118] The same SCS for cells can include: the same SCS for the active BWP of the cell; and / or the same SCS for the default BWP of the cell.

[0119] In this embodiment of the application, optionally, the search space has P common search space types and Q terminal-specific search space types, where P and Q are both integers greater than 1;

[0120] The R search space groups may include at least one of the following:

[0121] The first search space group corresponds to the P types of public search space and the Q types of terminal-specific search space, that is, the first search space group corresponds to all search space types;

[0122] The second search space group corresponds to all or part of the P common search space types, that is, the second search space group corresponds to some or all CSS types;

[0123] The third search space group corresponds to all or part of the Q terminal-specific search space types, that is, the third search space group corresponds to some or all CSS types;

[0124] The fourth search space group corresponds to all or part of the P-type public search space types and all or part of the Q-type terminal-specific search space types, that is, the fourth search space group corresponds to some or all CSS types and some or all CSS types.

[0125] A search space group corresponds to a certain search space type, which can be understood as: the search space includes the search space of that search space type.

[0126] 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 R search space groups match the terminal's PDCCH monitoring capabilities. Specific details are as follows:

[0127] Optionally, before the terminal receives the first information, the method may further include:

[0128] The terminal sends a second message, which is used to indicate the terminal's PDCCH monitoring capability information.

[0129] Optionally, the PDCCH monitoring capability information may include at least one of the following:

[0130] The first sub-information is used to indicate whether the target search space group supports PDCCH monitoring capability based on time slot group;

[0131] The second sub-information is used to indicate whether the target search space group supports PDCCH monitoring capability based on time slot level span;

[0132] The third sub-information is used to indicate at least one of the following: the number of cells supported by the target search space group for PDCCH monitoring capability based on time slot groups; the number of cells supported by the target search space group for PDCCH monitoring capability based on time slot span.

[0133] The fourth sub-information is used to indicate whether the target cell supports any of the following: PDCCH monitoring capability based on time slot groups; PDCCH monitoring capability based on time slot span; PDCCH monitoring capability corresponding to the first version, wherein the PDCCH monitoring capability corresponding to the first version is either PDCCH monitoring capability based on time slot groups or PDCCH monitoring capability based on time slot span, and the target cell is any cell in the cell set;

[0134] The target search space group is one of the R search space groups.

[0135] In this embodiment of the application, when the terminal indicates its own PDCCH monitoring capability information, it can indicate it at the granularity of the search space group, thereby improving the flexibility of the search space configuration.

[0136] The first version can be Release 17 or a later version.

[0137] Optionally, if the first sub-information indicates that the target search space group supports time slot-based PDCCH monitoring capabilities, the PDCCH monitoring capability information of the target search space group further includes at least one of the following:

[0138] The number of time slots included in a time slot group is X1;

[0139] The time offset O1 of the starting time slot of the time slot group;

[0140] The number of configurable PDCCH monitoring locations Y1 within a time slot group.

[0141] Optionally, if the second sub-information indicates that the target search space group supports PDCCH monitoring capability based on time slot span, the PDCCH monitoring capability information of the target search space group further includes at least one of the following:

[0142] Minimum number of time slots between consecutive time slot level spans x 2;

[0143] The maximum number of consecutive time slots Y2 in the time slot level span;

[0144] The number of slots M contained in a unit of time corresponding to the time slot level span;

[0145] The time offset O1 per unit time corresponding to the time slot level span.

[0146] Since the terminal indicates PDCCH monitoring capability information at the granularity of search space groups, optionally, the PDCCH monitoring capability information of the R search space groups may be the same or different. That is, the PDCCH monitoring capability information of different search space groups may be the same or different. Specifically, it can be manifested as: at least one of X1, O1 and Y1 above is the same or different, and / or at least one of X2, Y2, M and O1 above is the same or different.

[0147] The following explains the limitations of the time-domain location of the PDCCH monitoring location.

[0148] First, the limitations of the time slot where the PDCCH monitoring location is located will be explained.

[0149] In this embodiment, the time slot restriction for the PDCCH monitoring location can be determined at the granularity of search space groups, thereby improving the flexibility of search space configuration. It is understood that the time slot restrictions for the PDCCH monitoring location in different search space groups can be the same or different.

[0150] Optionally, if the target search space group corresponds to the PDCCH monitoring capability based on time slot groups, the time slot where the monitoring location of the target search space group is located satisfies a second condition, the second condition including at least one of the following:

[0151] Within the first Y1 time slots of the time slot group;

[0152] Within a consecutive Y1 time slot of the time slot group;

[0153] The number of time slots in the time slot group is no greater than Y1;

[0154] Wherein, the target search space group is one of the R search space groups; Y1 is the number of configurable PDCCH monitoring locations within the time slot group.

[0155] When a target search space group corresponds to a time slot-based PDCCH monitoring capability, for the target search space group, its corresponding target cell group can be determined first, and then the target time slot corresponding to the target cell group can be determined. The target time slot is configured with a PDCCH monitoring location. When the target cell group includes at least two cells, the target time slot corresponding to the target cell group can be: the set of target time slots corresponding to each cell in the target cell group.

[0156] For the target time slot corresponding to the determined target cell group, the location of the time slot group can be determined according to X1 and / or O1. The time slot where the monitoring location of the target search space group is located satisfies at least one of the following:

[0157] Within the first Y1 time slots of the defined time slot group;

[0158] Within a consecutive Y1 time slots of a defined time slot group;

[0159] The number of time slots in a given time slot group is no greater than Y1.

[0160] Optionally, when the R search space groups include at least two search space groups corresponding to PDCCH monitoring capabilities based on time slot groups, the second condition satisfied by the time slots where the detection positions of the at least two search space groups are located is the same or different. That is, the restrictions on the time slots where the PDCCH monitoring positions of different search space groups are located can be the same or different, specifically, Y1 in the second condition can be the same or different.

[0161] Optionally, when the target search space group corresponds to a PDCCH monitoring capability based on a time slot-level span, and the time slot-level span pattern is determined based on the first rule, the time slot where the monitoring location of the target search space group is located satisfies a third condition, the third condition including:

[0162] The distance between the starting time slots of a continuous time slot span is not less than X2 time slots;

[0163] Wherein, the target search space group is one of the R search space groups; X2 is the minimum number of time slots between consecutive time slot level spans.

[0164] When the target search space group corresponds to the PDCCH monitoring capability based on slot-level span, the slot-level span pattern, i.e., the slot-granular span pattern, can be determined according to the slot location of the PDCCH monitoring position in the target search space group and the first rule. In this case, the slots where the monitoring position of the target search space group is located satisfy the following condition: the distance between the starting slots of any consecutive slot-level span is not less than X2 slots.

[0165] Optionally, when the R search space groups include at least two search space groups corresponding to PDCCH monitoring capabilities based on time slot spans, the third condition satisfied by the time slots where the detection positions of the at least two search space groups are located is the same or different. That is, the restrictions on the time slots where the PDCCH monitoring positions of different search space groups are located can be the same or different, specifically, X2 in the third condition can be the same or different.

[0166] Optionally, when the time slot span corresponds to Q unit time, where Q is an integer greater than 1, the first rule includes at least one of the following:

[0167] 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 Y time slots.

[0168] 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 Y time slots.

[0169] Wherein, the first unit time is any one of the Q unit times; i is a positive integer.

[0170] 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.

[0171] 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.

[0172] Secondly, the limitations on the symbols used for PDCCH monitoring locations are explained.

[0173] In this embodiment, the time slot restriction for the PDCCH monitoring location can be determined at the granularity of search space groups, thereby improving the flexibility of search space configuration. It is understood that the time slot restrictions for the PDCCH monitoring location in different search space groups can be the same or different.

[0174] Furthermore, the restrictions on the symbols containing the PDCCH monitoring locations within the search space group can be applied at the granularity of a single symbol or at the granularity of a single symbol-level span. For different granularities, the conditions that the symbols containing the PDCCH monitoring locations must meet can differ, as detailed below:

[0175] Optionally, the symbol of the monitoring location of the target search space group satisfies a fourth condition, which includes at least one of the following:

[0176] Within the first Y' symbols of the time slot;

[0177] Within a consecutive Y' symbols of the time slot;

[0178] The number of symbols in a time slot is no greater than Y';

[0179] Wherein, the target search space group is one of the R search space groups; Y' is a positive integer, and Y' can be reported by the terminal, configured by the network-side device, or predefined by the protocol.

[0180] In this case, the restriction on the symbol where the PDCCH monitoring location of the search space group is located is performed at the granularity of a single symbol. The time slot in the fourth condition can be understood as any time slot in the target time slot corresponding to the target search space group.

[0181] Optionally, the fourth condition satisfied by the time slots of the R search space groups may be the same or different. That is, the restrictions on the symbols of the PDCCH monitoring positions of different search space groups may be the same or different, specifically, Y' in the fourth condition may be the same or different.

[0182] Optionally, when the symbol-level span pattern is determined based on the second rule, the symbol containing the monitored location in the target search space satisfies the fifth condition, which includes:

[0183] The distance between the starting symbols of consecutive symbol-level spans is not less than X' symbols;

[0184] Wherein, the target search space group is one of the R search space groups; X' is a positive integer, which can be reported by the terminal, configured by the network-side device, or predefined by the protocol.

[0185] In this case, the restriction on the symbols where the PDCCH monitoring positions of the search space group are located is granular at the single symbol-level span. The symbol-level span pattern, i.e., the symbol-level span pattern, can be determined based on the symbols where the PDCCH monitoring positions of the target search space are located and the second rule. In this case, the symbols where the PDCCH monitoring positions of the target search space are located can satisfy the following condition: the distance between the starting symbols of any consecutive symbol-level span is not less than X' symbols.

[0186] Optionally, the fifth condition satisfied by the time slots containing the R search space groups may be the same or different. That is, the restrictions on the symbols of the PDCCH monitoring positions of different search space groups may be the same or different, specifically, X' in the fifth condition may be the same or different.

[0187] Optionally, when the symbolic span corresponds to K units of time, where K is an integer greater than 1, the second rule includes at least one of the following:

[0188] 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.

[0189] 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.

[0190] Wherein, the second unit time is any one of the K unit times; i is a positive integer.

[0191] 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.

[0192] 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.

[0193] The following explains the limitations of the PDCCH processing parameters corresponding to the search space group.

[0194] Optionally, the PDCCH processing parameters corresponding to the R search space groups satisfy at least one of the following:

[0195] Method 1: The PDCCH processing parameters corresponding to the R search space groups are determined based on the PDCCH monitoring capabilities of the reference search space groups;

[0196] Method 2: The PDCCH processing parameters corresponding to the M search space groups are determined independently.

[0197] In method 1, one search space group can be selected from the R search space groups as a reference search space group. Then, based on the PDCCH monitoring capability corresponding to the reference search space group, the calculation method of the PDCCH processing parameters corresponding to the R search space groups is determined.

[0198] For determination method 1, optionally, the PDCCH processing parameters corresponding to the target search space group satisfy at least one of the following:

[0199] i) When the reference search space group has PDCCH monitoring capability based on time slot group, the PDCCH processing parameters corresponding to the target search space group are calculated based on the first time slot group, where the first time slot group is the time slot group of the reference search space group.

[0200] ii) When the reference search space group corresponds to the PDCCH monitoring capability based on the time slot level span, the PDCCH processing parameters corresponding to the target search space group are calculated based on the second time slot group, and the second time slot group is determined based on the time slot level span mode.

[0201] In this optional embodiment, the calculation method of the PDCCH processing parameters corresponding to the target search space group is different for different manifestations of multi-slot-based PDCCH monitoring capabilities.

[0202] In i), when determining the constraints of the PDCCH processing parameters corresponding to the target search space group, the PDCCH processing parameters corresponding to the target search space group in the time slot group of each reference search space group are statistically analyzed at the time slot group of each reference search space group, and the PDCCH processing parameters corresponding to the target search space group in the time slot group of each reference search space group meet the first constraint of the PDCCH processing parameters.

[0203] In ii), when determining the constraints of the PDCCH processing parameters corresponding to the target search space group, the second time slot group is first determined based on the span pattern at the time slot granularity. Then, using the second time slot group as the granularity, the PDCCH processing parameters corresponding to the target search space group in each second time slot group are statistically analyzed. The PDCCH processing parameters corresponding to the target search space group in each second time slot group meet the first constraint of the PDCCH processing parameters.

[0204] Optionally, the second time slot group satisfies:

[0205] The starting time slot is the starting time slot of the i-th time slot level span;

[0206] The end slot is the slot preceding the starting slot of the (i+1)th slot level span;

[0207] Where i is a positive integer.

[0208] 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 expressed as a target value.

[0209] When the PDCCH processing parameters are expressed as the number of BDs, the sum of the PDCCH processing parameters for each time slot 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 group of each cell group is less than or equal to the target value.

[0210] 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.

[0211] For determination method 2, the PDCCH processing parameters corresponding to the M search space groups are determined independently. Specifically, the PDCCH processing parameters for each search space group can be determined based on the PDCCH monitoring capability of that search space group. In this method, separate PDCCH monitoring capability parameter restrictions can exist for different search space groups.

[0212] When determining the constraints of the PDCCH processing parameters corresponding to the target search space group, the PDCCH processing parameters corresponding to the target search space group in the time slot group of each target search space group are statistically analyzed at the granularity of the time slot group. The PDCCH processing parameters corresponding to the target search space group in the time slot group of each target search space group meet the first constraint of the PDCCH processing parameters.

[0213] See Figure 3 , Figure 3 This is the second flowchart of the PDCCH monitoring method provided in the embodiments of this application.

[0224] The number of time slots included in a time slot group is X1;

[0225] The time offset O1 of the starting time slot of the time slot group;

[0226] The number of configurable PDCCH monitoring locations Y1 within a time slot group.

[0227] Optionally, if the second sub-information indicates that the target search space group supports PDCCH monitoring capability based on time slot span, the PDCCH monitoring capability information of the target search space group further includes at least one of the following:

[0228] Minimum number of time slots between consecutive time slot level spans x 2;

[0285] ii. The positions of the symbols determined in step a above are all within Y' consecutive symbols of the slot;

[0286] iii. The number of symbols determined in step a above in a slot does not exceed Y'.

[0287] c) If the PDCCH monitoring capability is defined based on the symbol level span, then the span pattern of the symbol granularity is determined according to the symbol position determined in step a and one of the following rules, the third condition being that the distance between the starting symbols of any consecutive symbol level span is not less than X' symbols.

[0288] i. 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.

The span pattern repeats at each unit of time.

[0290] The unit time is either a predefined slot or a span based on slot granularity determined in weight 5.

[0291] 7. The fourth condition is:

[0292] a) Using a specific first search space group in the first search space group set as a reference search space group, calculate the PDCCH monitoring capability parameter limit based on the PDCCH monitoring capability determined by that group.

[0293] i. If the reference search space group adopts multi-slot PDCCH monitoring capability based on (X, Y) slot group, the PDCCH monitoring capability parameter is calculated based on the slot group of the search space group, that is, the PDCCH configured in all search spaces in the slot group meets the PDCCH monitoring capability parameter limit.

[0294] ii. If the reference search space group adopts multi-slot PDCCH monitoring capability based on (X, Y) slot span, the PDCCH monitoring capability parameter is calculated based on the slot group determined according to the slot span pattern, which is from the start slot of one span to the start slot of the next span (excluding), that is, all search space configured PDCCH in the slot group conform to the PDCCH monitoring capability parameter limit.

[0295] b) The configured PDCCH monitoring capability parameters are processed separately for all search space groups in the first search space group set, that is, there are separate PDCCH monitoring capability parameter restrictions for different search space groups.

[0296] 8. When the first search space groups are different, the corresponding first conditions can be the same or different;

[0297] 9. When the first search space group is different, the corresponding PDCCH monitoring capability information can be the same or different.

[0298] For different first search space groups, the UE reports or the base station configures different PDCCH monitoring capability-related parameters.

[0299] Network-side devices can perform at least one of the following:

[0300] Receive PDCCH monitoring capability parameters reported by the UE;

[0301] Configure the relevant parameters for the UE's PDCCH monitoring capability in each cell;

[0302] Configure the search space according to the PDCCH monitoring capabilities.

[0303] Example 1:

[0304] In this embodiment, the PDCCH monitoring method may include the following steps:

[0305] Step 1: The UE reports the relevant values ​​(X1, Y1) of PDCCH monitoring capability for Type 1 CSS configured for Type 0, 0A, 2 CSS and non-dedicated RRC, and the relevant values ​​(X2, Y2) of PDCCH monitoring capability for Type 1, Type 3 CSS and USS configured for dedicated RRC.

[0306] Step 2: Configure the search space for the UE to receive the base station.

[0307] Determine the slot for the PDCCH monitoring occasion with Type 1 CSS configured with Type 0, 0A, 2 CSS and non-dedicated RRC configuration, and determine the slot-granular span pattern based on (X1, Y1), where the starting slot between any consecutive spans is no less than X1 slots.

[0308] Identify the slots for PDCCH monitoring occasions of Type 1, Type 3 CSS, and USS with dedicated RRC configurations, and determine the slot-granular span pattern based on (X2, Y2), where the starting slots between any consecutive spans are no less than X2 slots.

[0309] The advantage of this approach is that the CSS configuration does not restrict the USS configuration of multiple UEs.

[0310] Step 3: Determine the limitations of PDCCH monitoring capability parameters.

[0311] Using Type 1, Type 3 CSS, and USS with dedicated RRC configurations as reference search space groups, the BD / CCE budget is calculated based on the slot-granular span pattern determined by (X2, Y2). The original per-span BD / CCE budget is extended to a slot group between two consecutive spans, and BD / CCE checks are performed on the PDCCH of all search spaces within this slot group. See [link to documentation]. Figure 4 .

[0312] The embodiments of this application include the following protection points:

[0313] UE reports or predefined PDCCH monitoring capability information;

[0314] The UE receives base station PDCCH configuration information, including search space configuration and / or PDCCH monitoring capability configuration;

[0315] The UE performs PDCCH monitoring according to the search space configured by the base station. The search space configured by the base station conforms to the PDCCH monitoring capability of the terminal. That is, for at least one first cell group in the first cell group set (one or more first cell groups) and at least one first search space group in the first search space group set (one or more first search space groups), the UE determines that the PDCCH monitoring occasion of the first search space group configured in the first cell group meets the corresponding first condition.

[0316] Wherein, the first cell group is all or part of all serving cells configured for the terminal, the first search space group is all or part of all search spaces, and the first condition includes at least one of the following:

[0318] The symbol for the PDCCH monitoring occasion satisfies the third condition;

[0319] The PDCCH monitoring capability parameters (such as the number of blind tests or the number of CCEs) meet the fourth condition.

[0320] Meanwhile, when the first search space group is different, the corresponding PDCCH monitoring capability information and / or first conditions can be the same or different.

[0321] As can be seen, in the embodiments of this application, at least one of the following can be performed at the granularity of search space groups: defining PDCCH monitoring capabilities, restricting the temporal location of PDCCH monitoring locations, and restricting PDCCH processing parameters, thereby improving the flexibility of search space configuration.
