[0052] To facilitate a more thorough understanding of the technical solutions provided in the embodiments of this application, the following content is now described:

[0053] 1. Definition of PDCCH monitoring capability of NR Rel-15

[0054] In NR Rel-15, the monitoring capabilities of PDCCH are divided into Mandatory and Optional capabilities.

[0055] First, the capabilities of mandatory signaling without capability are as follows:

[0056] CORESET (Control-resource set): Each BWP (Bandwidth Part) of each cell can be configured with one additional CORESET on top of CORESET 0.

[0057] -FR1: 6RB (Resource Block) bitmap + 1 to 3 symbols.

[0058] -FR2: Bitmap + 1 to 3 symbols for Type 1, 6RB with Type 0, 0A, 2 CSS (Common Search Space) and non-dedicated RRC (Radio Resource Control) configurations; bitmap + 1 to 2 symbols for Type 1, Type 3 and USS with dedicated RRC configurations.

[0059] -REG (Resource Element Group) bundle size: 2 / 3 / 6.

[0060] - Mapping of Interleaved and Non-interleaved CCEs (Control Channel Elements) to REGs.

[0061] - Supports configuring the precoder granularity size (high-level parameter size) as the REG bundle size.

[0062] - Supports DM-RS scrambling.

[0063] - Supports configuring one or more TCI (Transmission Configuration Indication) states.

[0064] Unicast PDCCH transmission in CSS and USS (User Specific Search Space)

[0065] -AL 1,2,4,8,16.

[0066] - For a scheduled SCell (Secondary Cell), each BWP has a maximum of 3 SS (Search Space) sets per slot (as defined by the scheduling Cell), and this limit is in place before SS dropping.

[0067] - For Type 1, Type 3 and USS of dedicated RRC configuration, monitoring occasions are the first 3 symbols in a slot.

[0068] - For Type 0, 0A, 2 CSS and Type 1 non-dedicated RRC configurations, monitoring occasions can be any 1 symbol in a slot and within a single span (3 consecutive OFDM symbols) in a slot.

[0069] -Supports monitoring of DCI 0_0,0_1,1_0,1_1.

[0070] - For FDD (Frequency Division Duplexing) systems, for each scheduled CC (Component Carrier), each slot processes only one DCI scheduled for DL ​​(Down Link) unicast transmission and one DCI scheduled for UL (Up Link) unicast transmission.

[0071] - For a TDD (Time Division Duplex) system, for each scheduled CC, each slot handles only one DCI scheduled for DL ​​unicast transmission and two DCI scheduled for UL unicast transmission.

[0072] Secondly, the capability of mandatory signaling with capability signaling is as follows:

[0073] CORESET in FR2

[0074] - For Type 1, Type 3 and USS with dedicated RRC configurations, 6RB bitmap + 3 symbols.

[0075] Finally, the capabilities of Optional are as follows:

[0076] pdcchMonitoringSingleOccasion

[0077] -FR1: Indicates that the UE supports receiving C-RNTI and CS-RNTI scrambled PDCCH for any 3 consecutive symbols in a 15kHz slot.

[0078] pdcch-MonitoringAnyOccasions

[0079] -withoutDCI-gap: For Type 1, Type 3 and USS of dedicated RRC configuration, monitoring occurrences are any 1 symbol in a slot and comply with the BD (Blind Decoding) budget.

[0080] -withDCI-gap: For Type 1, Type 3, and USS dedicated RRC configurations, monotroing occasions may occur on any one symbol in a slot, but any two consecutive PDCCHs scrambled with C-RNTI, MCS-C-RNTI, or CS-RNTI must meet the gap (interval) restrictions: 2 symbols for 15kHz (2 symbols for 15kHz), 4 symbols for 30kHz (4 symbols for 30kHz), 7 symbols for (60kHz, NCP) (7 symbols for (60kHz, NCP), 14 symbols for 120kHz (14 symbols for 120kHz), and comply with BD budget restrictions.

[0081] pdcch-MonitoringAnyOccasionsWithSpanGap

[0082] - The span pattern is determined based on the (X, Y) values ​​of the UE reporting configured for all SS monitoring occasions: the span pattern is the same for each slot; the starting position of the first span of the span pattern is the position of the first monitoring occasion in any slot, and the span length is max{maximum value of all CORESET durations, minimum value of Y in the UE reported candidatevalue}, while the last span may be slightly shorter; the starting position of the next span is the first position of the monitoring occasion not included in the previous span.

[0083] - Check if the span pattern satisfies at least one (X,Y) constraint of the reporting.

[0084] 2. Definition of PDCCH monitoring capability of NR Rel-16

[0085] In NR Rel-16, all PDCCH monitoring capabilities are optional, as shown below:

[0086] 2.1 pdcch-Monitoring-r16: Unlike Rel15, it can report the supported span values ​​per PDSCH (Physical Downlink Shared Channel) processing type and per SCS, and each span conforms to the corresponding BD / CCE limit.

[0087] 2.2 pdcch-MonitoringMixed-r16: Supports different pdcch monitoring capability configurations for different serving cells.

[0088] 2.3, 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 spanarrangement is aligned.

[0089] The processing method for PDCCH monitoring capabilities provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0090] Figure 2 This is one of the flowcharts illustrating the processing method for PDCCH monitoring capabilities provided in this application embodiment. For example... Figure 2 As shown in the embodiment of this application, a method for processing PDCCH monitoring capabilities is provided. This method is applied to a terminal and may include:

[0091] S210. Determine the physical downlink control channel (PDCCH) monitoring capability. The PDCCH monitoring capability represents the constraints that the time slots that the terminal UE can monitor must meet.

[0092] S220, PDCCH monitoring capability;

[0093] The PDCCH monitoring capability includes any one or a combination of the following:

[0094] Monitoring is only performed on predetermined time slots of radio frames, radio subframes, or time slot groups.

[0095] The monitoring can be performed on any time slot of a wireless frame, wireless subframe, or time slot group.

[0096] It should be noted that the above method can be executed by a terminal. The technical solution of this application will be explained in detail below using the execution of the above method by a terminal as an example.

[0097] First, the UE can determine its PDCCH monitoring capability, that is, determine the constraints that the UE needs to meet for the time slots it can monitor.

[0098] Once the PDCCH monitoring capability is determined, the UE can send the PDCCH monitoring capability to the network so that the network can configure the corresponding resources for the UE based on the PDCCH monitoring capability, such as configuring the corresponding PDCCH for the UE.

[0099] In one embodiment, under a first preset condition, the monitoring timing is only on a predetermined time slot of a radio frame, radio subframe, or time slot group; while under a second preset condition, the monitoring timing is on any time slot of a radio frame, radio subframe, or time slot group.

[0100] The first preset scenario can be for all search spaces or for Type 1, Type 3, and user-specific search spaces (USS) configured for dedicated radio resource control (RRC).

[0101] The second preset case can be for all search spaces or for Type 1 cases for Type 0, 0A, 2 public search space CSS and non-dedicated RRC configurations.

[0102] In the first preset scenario, the monitoring timing (the timing when the UE performs PDCCH monitoring) can be limited to a predetermined time slot within a radio frame, radio subframe, or time slot group. That is, in the first preset scenario, the UE can only perform PDCCH monitoring within that predetermined time slot.

[0103] In the second preset scenario, the monitoring timing can be any time slot within a radio frame, radio subframe, or time slot group. That is, in the second preset scenario, the UE can perform PDCCH monitoring on any time slot within a radio frame, radio subframe, or time slot group.

[0104] The PDCCH monitoring capability processing method provided in this application determines whether to perform PDCCH monitoring on a predetermined time slot or any time slot of a radio frame, radio subframe, or time slot group based on different situations. Compared with the prior art, which mechanically defines PDCCH monitoring capability according to the granularity of each time slot or segment, it can effectively reduce the complexity of UE to implement PDCCH monitoring, thereby significantly improving communication efficiency and reducing UE power consumption, and has a very broad application prospect.

[0105] In one embodiment of this application, the predetermined time slot may include any of the following:

[0106] A preset number of time slots preceding a wireless frame, wireless subframe, or time slot group;

[0107] A preset number of time slots following a wireless frame, wireless subframe, or time slot group;

[0108] A time slot with a preset number of time slots in a wireless frame, wireless subframe, or time slot group.

[0109] The preset number can be, for example, 2 or 3, and its specific size can be adjusted according to actual needs. This application embodiment does not impose a specific limitation on this.

[0110] When the preset number is 2, the preset time slot can be the first 2 or the last 2 time slots of a radio frame, or the first 2 or the last 2 time slots of a radio subframe, or the first 2 or the last 2 time slots of a time slot group.

[0111] The number of preset time slots can be, for example, 4 or 5, and its specific size can be adjusted according to actual needs. This application does not impose a specific limitation on this.

[0112] When the preset number of time slots is 4, the preset time slots can be time slots that are every 4 time slots in a radio frame. For example, when the first preset time slot is the second time slot of a radio frame, the subsequent preset time slots (the second preset time slot, the third preset time slot, etc.) can be the 7th time slot, the 12th time slot, etc. of the radio frame. The preset time slots can also be time slots that are every 4 time slots in a radio subframe. For example, when the first preset time slot is the second time slot of a radio subframe, the subsequent preset time slots (the second preset time slot, the third preset time slot, etc.) can be the 7th time slot, the 12th time slot, etc. of the radio subframe. The preset time slots can also be time slots that are every 4 time slots in a time slot group. For example, when the first preset time slot is the second time slot of a time slot group, the subsequent preset time slots (the second preset time slot, the third preset time slot, etc.) can be the 7th time slot, the 12th time slot, etc. of the time slot group.

[0113] The PDCCH monitoring capability processing method provided in this application improves the flexibility of PDCCH monitoring because the predetermined time slot can be on multiple time slots of a radio frame, radio subframe, or time slot group.

[0114] In one embodiment, the PDCCH monitoring capability further includes any one of the following:

[0115] In the first preset case, the monitoring timing is on any time slot of a wireless frame, wireless subframe, or time slot group;

[0116] In the first preset case, the monitoring timing is on any time slot of a radio frame, radio subframe, or time slot group, and any consecutive PDCCHs satisfy the preset interval.

[0117] The preset interval can be pre-set or determined according to the specific size of the SCS. For example, for a 480kHz SCS, the preset interval can be 4 time slots, while for a 960kHz SCS, the preset interval can be 8 time slots.

[0118] It should be noted that the aforementioned PDCCH monitoring capability can be considered an optional capability for PDCCH monitoring. That is, when a UE possesses the aforementioned PDCCH capability, it will report this capability to the network, and the network will only configure the corresponding resources for the UE if the UE reports this capability.

[0119] Correspondingly, the PDCCH monitoring capability mentioned in the above embodiments (in the first preset case, the monitoring timing is only on a predetermined time slot of a radio frame, radio subframe, or time slot group; and in the second preset case, the monitoring timing is on any time slot of a radio frame, radio subframe, or time slot group) can be used as the mandatory capability for PDCCH monitoring. That is, the PDCCH monitoring capability can be as specified by the protocol: the UE needs to implement PDCCH monitoring according to the monitoring capability, and the network needs to configure corresponding resources for the UE according to the monitoring capability.

[0120] Of course, the optional and mandatory capabilities of the PDCCH monitoring mentioned above can be interchanged according to time slot requirements.

[0121] For example, in one embodiment, the optional capability of PDCCH monitoring (in a first preset case, the monitoring timing is on any time slot of a radio frame, radio subframe, or time slot group; or in a preset case, the monitoring timing is on any time slot of a radio frame, radio subframe, or time slot group, and any consecutive PDCCHs satisfy a preset interval) can actually be used as a mandatory capability for PDCCH monitoring between the UE and the network; while the mandatory capability of PDCCH monitoring (in a first preset case, the monitoring timing is only on a predetermined time slot of a radio frame, radio subframe, or time slot group; and in a second preset case, the monitoring timing is on any time slot of a radio frame, radio subframe, or time slot group) can actually be used as an optional capability for PDCCH monitoring between the UE and the network.

[0122] Of course, the optional and mandatory capabilities of PDCCH monitoring can also be combined according to time slot requirements.

[0123] For example, in one embodiment, the Optional and Mandatory capabilities of PDCCH monitoring described above can both be used as Mandatory capabilities that the UE and the network must comply with when performing PDCCH monitoring; or they can be used as Optional capabilities that the UE and the network can choose to comply with when performing PDCCH monitoring.

[0124] The PDCCH monitoring capability processing method provided in this application embodiment can further improve the flexibility of PDCCH monitoring by flexibly dividing the PDCCH monitoring capability into Mandatory capability and Optional capability according to actual needs.

[0125] In one embodiment, the time slot group can be determined in the following way:

[0126] Determine the number of time slots N or the set of time slots {Ni} contained in a time slot group. It can be understood that each time slot group corresponds to one number of time slots N. When there are multiple time slot groups, there will be multiple timeslot numbers N (N can have different values), and these multiple timeslot numbers N constitute the time slot set {Ni}. The elements within the time slot set {Ni} (the number of time slots N in different time slot groups) can be the same or different from each other.

[0127] The location of the time slot group is determined based on the determined number of time slots N or the set of time slots {Ni}.

[0128] Alternatively, the number of time slots N or the set of values ​​{Ni} can be obtained in one of the following ways:

[0129] Method 1: Obtain via network configuration;

[0130] The network can allocate a number of time slots to each time slot group according to actual needs, such as the parameters of the data to be transmitted (size, frequency, etc.) and the time domain resource usage. Thus, the number of time slots N to be included in the time slot group (when there is only one time slot group) or the set of time slots {Ni} (when there are multiple time slot groups) can be determined.

[0131] Method 2: Obtain the number of multiple downlink shared physical channels (PDSCHs) or time slots that can be scheduled through the downlink control information (DCI) time-domain scheduling parameters;

[0132] The network can determine the number of time slots N based on the number of schedulable PDSCHs or time slots according to the DCI time-domain scheduling parameters. The number of time slots N can correspond one-to-one with the number of schedulable PDSCHs or time slots, or it can be proportional to the number of schedulable PDSCHs or time slots, for example, a ratio of 2:1. For instance, when the number of schedulable PDSCHs or time slots is 4, the number of time slots N can be 8.

[0133] The total number of schedulable PDSCHs or time slots can be used as the number of time slots to be included in different time slot groups. Alternatively, the maximum or minimum value of the number of schedulable PDSCHs or time slots in the DCI time domain scheduling parameters can be used as the number of time slots to be included in a time slot group.

[0134] Method 3: Obtained through capability parameters reported by the UE. These capability parameters include the number of time slots N or the set of time slots {Ni}, or the number of multiple PDSCHs or time slots that can be scheduled by the DCI time domain scheduling parameters.

[0135] The number of time slots N or the set of time slots {Ni} can be determined based on the capability parameters reported by the UE to the network. Here, the capability parameters are those related to the UE's PDCCH monitoring capabilities.

[0136] The capability parameters may include the number of time slots N or the set of time slots {Ni}. When there are multiple time slots N, each time slot N can be used as the number of time slots to be included in different time slot groups; or, the maximum or minimum value, or the median or average value among all the time slots N can be used as the number of time slots to be included in a time slot group.

[0137] The capability parameters can also include the number of PDSCHs or time slots that can be scheduled by a DCI time-domain scheduling parameter. All values ​​of the number of PDSCHs or time slots that can be scheduled by a single DCI time-domain scheduling parameter can be used as the number of time slots to be included in different time slot groups. Alternatively, the maximum, minimum, median, or average value of the number of PDSCHs or time slots that can be scheduled by a single DCI time-domain scheduling parameter can be used as the number of time slots to be included in a time slot group.

[0138] In one embodiment, the capability parameter may further include one or more of the following parameters:

[0139] The number of time slots contained in a time slot group;

[0140] The gap value between time slots or time slot groups;

[0141] BD budget value or CCE budget value.

[0142] Among them, the BD budget value can refer to the budget value of the number of PDCCH Candidates corresponding to the predetermined time slot; the CCE budget value can refer to the budget value of the number of CCEs required for blind inspection.

[0143] After receiving the capability parameter reported by the UE, the network will configure the corresponding resources for the UE based on the capability parameter so that the UE can perform PDCCH monitoring.

[0144] Method 4: Obtain the number of time slots N or the set of time slots {Ni} predefined by the protocol.

[0145] The UE and the network can also follow the relevant provisions of the protocol to perform PDCCH monitoring or resource configuration according to the number of time slots N or the set of time slots {Ni} predefined in the protocol.

[0146] Understandably, without conflict, the number of time slots N or the set of time slots {Ni} can also be determined by combining the methods described above. For example, the number of slots N or the set of time slots {Ni} can be determined by combining the maximum or minimum values ​​from methods 2 and 3.

[0147] The PDCCH monitoring capability processing method provided in this application improves the feasibility of implementing PDCCH monitoring because it can determine the number of time slots or the set of values ​​through the various methods described above.

[0148] In one embodiment, the location of the time slot group can be determined in one of the following ways:

[0149] Method I: Determined by any N consecutive time slots;

[0150] Once the number of time slots N or the set of time slots {Ni} in a time slot group is determined, the location of the time slot group can be determined based on the determined number of time slots N.

[0151] In Mode I, the position of the time slot group can be any consecutive N time slots. For example... Figure 4 As shown, when the number of time slots is 4, the position of the time slot group can be any 4 consecutive time slots in Subframe #0 and Subframe #1, such as... Figure 3 The time slots are group 1, time slot 2, and time slot 3.

[0152] Method II: In slot bundling of radio frames, radio subframes or slots, every N slots starting from the first slot form a slot group, and the last slot of the last radio frame, radio subframe or slot bundling is the end slot. The pattern of the slot group is repeated in each radio frame or radio subframe.

[0153] In this context, a slot bundling is a unit with multiple consecutive time slots, and the number of time slots contained in a slot bundling is greater than or equal to the number of time slots contained in a time slot group.

[0154] Method III: Use the time slots configured by the network or reported by the UE as the starting time slot or reference time slot, and determine the position of the time slot group based on the starting time slot or reference time slot and the number of time slots N;

[0155] In Mode III, the starting time slot or reference time slot can be determined based on the network configuration or the time slot reported by the UE to the network. Starting from the starting time slot or reference time slot, every N consecutive or discontinuous time slots can be used as the position of the time slot group.

[0156] Alternatively, a reference time slot can be used as a reference point. Starting from a preset number of time slots before or after the reference time slot, every N consecutive or discontinuous time slots can be used as the position of a time slot group. For example, it can start from a time slot that is 2 time slots away from the reference time slot, that is, from the 3rd time slot after the reference time slot, and every 4 consecutive time slots can be used as the position of a time slot group.

[0157] like Figure 4As shown, the first slot #0 in the subframe #0 can be used as the starting slot, and every four consecutive slots starting from slot #0 can be a slot group, such as slot group 1, slot group 2, slot group 3, etc.

[0158] like Figure 5 As shown, a time slot in Subframe #0 can also be used as a reference time slot. Starting from this reference time slot, every four consecutive time slots form a time slot group, such as time slot group 1, time slot group 2, time slot group 3, etc.

[0159] Method IV: Determine the pattern of the time slot group based on the monitoring timing configured in the search space SS.

[0160] The location of a time slot group can be determined by combining the monitoring timing configured in the SS with the number of time slots N in the time slot group. After determining the location of the time slot group, the pattern of the time slot group in the radio frame, radio subframe, or slot bundling can be determined based on the location of each time slot group.

[0161] The PDCCH monitoring capability processing method provided in this application, by determining the location of the time slot group through the above-mentioned methods, can further improve the feasibility of realizing PDCCH monitoring.

[0162] In one embodiment, determining the pattern of the time slot group based on the monitoring timing configured in the SS configuration may include:

[0163] The pattern of the time slot group repeats in each radio frame or radio subframe or slot bundling;

[0164] The first time slot group starts at the first time slot in a radio frame, radio subframe, or slot bundling where there is a monitoring opportunity. N time slots starting from the start of the first time slot group constitute the first time slot group. The next time slot group starts at the first time slot in a radio frame, radio subframe, or slot bundling where there is a monitoring opportunity. N time slots starting from the start of the next time slot group constitute a time slot group. This process continues until the last time slot group ends at the end of a radio frame, radio subframe, or slot bundling.

[0165] like Figure 6As shown, darker colors indicate monitoring opportunities. Time slot group 1 is the first time slot group in subframe #0. Its starting time slot is the first time slot (the 4th time slot) in subframe #0 that has a monitoring opportunity. The four time slots starting from this time slot form time slot group 1. Time slot group 2 is the second time slot group in subframe #0. Its starting time slot is the first time slot (the 16th time slot) that has a monitoring opportunity but is not in time slot group 1. The four time slots starting from this time slot form time slot group 2.

[0166] Since the pattern of the time slot group is repeated in each radio frame, radio subframe, or slot bundling, the pattern of the time slot group in subframe #1 needs to be consistent with the pattern of the time slot group in subframe #0. That is, the starting point of time slot group 1' is the 4th time slot in subframe #1, and the 4 time slots starting from this time slot constitute time slot group 1'; the starting point of time slot group 2' is the 16th time slot in subframe #1, and the 4 time slots starting from this time slot constitute time slot group 2'.

[0167] In one embodiment, determining the pattern of the time slot group based on the monitoring timing configured in the SS configuration may include:

[0168] The pattern of a time slot group is different in each radio frame or radio subframe;

[0169] For each radio frame, radio subframe, or slot bundling, the first time slot group starts at the first time slot in the radio frame, radio subframe, or slot bundling where there is a monitoring opportunity. N time slots starting from the start of the first time slot group constitute the first time slot group. The next time slot group starts at the first time slot in the radio frame, radio subframe, or slot bundling where there is a monitoring opportunity. N time slots starting from the start of the next time slot group constitute a time slot group. This process continues until the last time slot group ends at the end of the radio frame, radio subframe, or slot bundling.

[0170] like Figure 7 As shown, darker colors indicate monitoring opportunities. Time slot group 1 is the first time slot group in subframe #0, starting from the first time slot in subframe #0 with a monitoring opportunity. The four time slots starting from this time slot constitute time slot group 1. Time slot group 2 is the second time slot group in subframe #0, starting from the first time slot with a monitoring opportunity that is not in time slot group 1. The four time slots starting from this time slot constitute time slot group 2.

[0171] Time slot group 3 is the first time slot group in subframe #1. Its starting point is the first time slot in subframe #1 with a monitoring opportunity. The four time slots starting from this time slot form time slot group 3. Time slot group 4 is the second time slot group in subframe #1. Its starting point is the first time slot with a monitoring opportunity that is not in time slot group 3. The four time slots starting from this time slot form time slot group 4.

[0172] Depend on Figure 7 It can be seen that in Subframe #0, time slot group 1 starts in the 4th time slot and time slot group 2 starts in the 16th time slot; while in Subframe #1, time slot group 3 starts in the 6th time slot and time slot group 4 starts in the 16th time slot. Therefore, the time slot group pattern is different in radio subframes #0 and #1.

[0173] In one embodiment, determining the pattern of the time slot group based on the monitoring timing configured in the SS configuration may include:

[0174] The time slot is used as the starting time slot or the reference time slot, and the pattern of the time slot group is determined from the starting time slot, or the pattern of the time slot group is determined from the starting time slot which is a preset number of time slots away from the reference time slot.

[0175] The first time slot group starts at the beginning of the time slot or the first time slot after the beginning of the time slot where there is a monitoring opportunity. N time slots starting from the beginning of the first time slot group constitute the first time slot group. The next time slot group starts at the first time slot that is not in any previous time slot group and has a monitoring opportunity. N time slots starting from the beginning of the next time slot group constitute a time slot group. The pattern of the time slot groups is determined in sequence.

[0176] It is understood that, in this embodiment, with Figure 7 The difference between the illustrated embodiment and the actual implementation is that the starting point of the first time slot group depends on the network configuration or the time slot reported by the UE. After determining the starting point of the first time slot group, the specific method for forming subsequent time slot groups can be the same as... Figure 7 The embodiments shown are the same and will not be described again here.

[0177] It should be noted that, in this embodiment, the pattern of the time slot group can be the same in each radio frame, radio subframe, or slot bundling, or it can be different in each radio frame, radio subframe, or slot bundling. This application embodiment does not specifically limit this.

[0178] In one embodiment, the time slot group satisfies one or more of the following conditions:

[0179] Condition 1: The distance between time slot groups is greater than or equal to the first predetermined value;

[0180] The specific size of the first predetermined value can be, for example, 5 time slots, 6 time slots, etc., and its specific size can be adjusted according to actual needs. This application embodiment does not specifically limit this.

[0181] Condition 2: The number of search space sets (SS sets) configured within each time slot group is less than or equal to a second predetermined value. This condition is limited to before the search space drop (SS dropping).

[0182] The specific size of the second predetermined value can be, for example, 2 or 3, and its specific size can be adjusted according to actual needs. This application embodiment does not specifically limit this.

[0183] Condition 3: The number of BDs or CCEs in each time slot group is less than or equal to the third predetermined value;

[0184] The specific size of the third predetermined value can be, for example, 8, 10, etc., and its specific size can be adjusted according to actual needs. This application embodiment does not specifically limit this.

[0185] Condition 4: The number of monitoring times for each time slot group is less than or equal to the fourth predetermined value. This condition applies before SS dropping.

[0186] The specific size of the fourth predetermined value can be, for example, 10, 12, etc., and its specific size can be adjusted according to actual needs. This application embodiment does not specifically limit this.

[0187] Condition 5: The number of monitoring times for each time slot in each time slot group is less than or equal to the fifth predetermined value, which is prior to SSdropping.

[0188] The specific size of the fifth predetermined value can be, for example, 4, 6, etc., and its specific size can be adjusted according to actual needs. This application embodiment does not specifically limit this.

[0189] The PDCCH monitoring capability processing method provided in this application embodiment can ensure the smooth operation of PDCCH monitoring based on time slot groups by making the time slot group meet one or a combination of the above-mentioned limiting conditions.

[0190] In one embodiment, the PDCCH monitoring capability further includes any one or a combination of the following:

[0191] Capability 1: For a scheduled secondary cell (Scell), for each subset bandwidth (BWP), there is a maximum of a first preset number of search space sets (SS sets) on each monitorable time slot of each radio frame, radio subframe, or time slot group, and this limitation is in place before performing search space dropping (SS dropping).

[0192] The specific size of the first preset quantity can be, for example, 2 or 3, and its specific size can be adjusted according to actual needs. This application embodiment does not specifically limit this.

[0193] Capability 2: For frequency division duplex (FDD) systems, for each scheduled carrier unit (CC), only a second preset number of downlink control information (DCI) for scheduled downlink unicast (DL) unicast transmissions and a third preset number of uplink unicast (UL) unicast transmissions are processed on each radio frame, radio subframe, or time slot group's monitorable time slots.

[0194] The specific sizes of the second preset quantity and the third preset quantity can be, for example, 1, 2, etc., and their specific sizes can be adjusted according to actual needs. This application embodiment does not specifically limit them.

[0195] Capability 3: For a time division duplex (TDD) system, for each scheduled CC, only a fourth preset number of downlink control information (DCI) transmitted via downlink unicast (DL) and a fifth preset number of uplink unicast (UL) unicast are processed on each monitorable time slot of each radio frame, radio subframe, or time slot group.

[0196] The specific sizes of the fourth and fifth preset quantities can be, for example, 1 or 2, and their specific sizes can be adjusted according to actual needs. This application embodiment does not specifically limit them.

[0197] It is understandable that, under certain circumstances, the first preset quantity, the second preset quantity, the third preset quantity, the fourth preset quantity, and the fifth preset quantity may be the same value, or multiple of them may be the same value.

[0198] The PDCCH monitoring capability processing method provided in this application embodiment can improve the adaptability of PDCCH monitoring and effectively expand the application scope of PDCCH monitoring by further subdividing the PDCCH monitoring capability according to different usage scenarios or working environments.

[0199] In one embodiment, the PDCCH monitoring capability may further include any one or more of the following:

[0200] Capability a: The time required for the UE to demodulate a specific DCI;

[0201] Among them, a specific DCI can be a DCI that enables PDCCH to schedule multiple PDSCHs.

[0202] Capability b: Minimum K0 or K2 constraint;

[0203] Capability c: The earliest time the UE can access the downlink shared physical channel buffer (PDSCH).

[0204] The PDCCH monitoring capability processing method provided in this application embodiment, by including the relevant parameters for service processing with the UE as part of the PDCCH monitoring capability, can ensure that appropriate resources are configured for the UE, thereby avoiding PDCCH monitoring failure due to insufficient UE capabilities.

[0205] In one embodiment, the PDCCH monitoring capability processing method provided in this application is applied to a specific frequency and / or subcarrier spacing (SCS).

[0206] In one embodiment, the PDCCH monitoring capability processing method provided in this application is applied to a UE that supports Redcap capability.

[0207] In one embodiment, the PDCCH monitoring capability processing method provided in this application may further include:

[0208] When the UE simultaneously supports Rel-15 / 16 and Rel-17 PDCCH monitoring capabilities, and the network is configured to support Rel17 capabilities, one of the following methods should be used:

[0209] This disables the PDCCH monitoring capability of Rel-15 / 16;

[0210] The PDCCH monitoring capability of Rel-15 / 16 is only valid on the monitorable time slots defined in Rel-17.

[0211] In one embodiment, step S220 may include: transmitting PDCCH monitoring capabilities per band, per band combination, or per feature set.

[0212] In one embodiment, the PDCCH monitoring capability is only supported when the UE reports support for the Multi-PDSCH / PUSCH capability.

[0213] In one embodiment, the PDCCH monitoring capability is mandatory or mandatory at a preset frequency and / or preset subcarrier spacing (SCS); or

[0214] PDCCH monitoring capability is optional or optional under preset frequency and / or preset subcarrier spacing (SCS).

[0215] The following specific examples illustrate the processing method for PDCCH monitoring capabilities provided in this application:

[0216] Example 1:

[0217] When the PDCCH is configured in the active BWP of the serving cell in the 52.6-71GHz range, and the SCS of the active BWP is 480 / 960kHz, the UE applies the following mandatory PDCCH monitoring capabilities:

[0218] For Type 0, 0A, 2CSS and Type 1 with non-dedicated RRC configuration, monitoring can be performed at any time slot;

[0219] For Type 1, Type 3 and USS with dedicated RRC configuration, the monitoring timing can be on time slots with a preset number of time slots in a subframe;

[0220] The preset number of time slots is 4 for 480kHz SCS and 8 for 960kHz SCS.

[0221] For a scheduled Scell, there are a maximum of L = 3 SS sets per monitorable time slot for each BWP, and this limit is in place before SS dropping.

[0222] For an FDD system, for each scheduled CC, only one DCI scheduled for DL ​​unicast transmission and one DCI scheduled for UL unicast transmission are processed on each measurable time slot.

[0223] For a TDD system, for each scheduled CC, each monitorable time slot processes only one DCI scheduled for DL ​​unicast transmission and two DCIs scheduled for UL unicast transmission.

[0224] Example 2:

[0225] When the PDCCH is configured in the active BWP of the serving cell in the 52.6-71GHz range, and the SCS of the active BWP is 480 / 960kHz, the UE can apply the following optional PDCCH monitoring capabilities:

[0226] For Type 1, Type 3, and USS with dedicated RRC configurations, monitoring can be performed at any time slot;

[0227] For Type 1, Type 3 and USS with dedicated RRC configuration, the monitoring timing can be any time slot in a subframe, and any consecutive PDCCHs must satisfy a certain interval value, i.e., be separated by g time slots; where g is 4 for SCS at 480KHz and 8 for SCS at 960KHz.

[0228] Figure 8 This is the second flowchart illustrating the processing method for PDCCH monitoring capability provided in this application embodiment. Figure 8 As shown in the embodiments of this application, a method for processing PDCCH monitoring capabilities is also provided. This method is applied to network-side devices and may include:

[0229] S810, capable of receiving PDCCH monitoring;

[0230] S820, based on PDCCH monitoring capability, sends PDCCH;

[0231] The PDCCH monitoring capability includes any one or a combination of the following:

[0232] Monitoring is only performed on predetermined time slots of radio frames, radio subframes, or time slot groups.

[0233] The monitoring can be performed on any time slot of a wireless frame, wireless subframe, or time slot group.

[0234] It should be noted that the above method can be implemented by a network-side device. The technical solution of this application will be explained in detail below using the example of a network-side device implementing the above method.

[0235] First, the UE can determine its PDCCH monitoring capability, that is, determine the constraints that the UE needs to meet for the time slots it can monitor.

[0236] Once the PDCCH monitoring capability is determined, the UE can send the PDCCH monitoring capability to the network-side equipment.

[0237] The network-side device receives the PDCCH monitoring capability sent by the UE and configures corresponding resources for the UE based on the PDCCH monitoring capability, such as configuring the corresponding PDCCH for the UE.

[0238] After configuring the PDCCH, the network-side device will send the PDCCH to the UE so that the UE can monitor the PDCCH.

[0239] In one embodiment, under a first preset condition, the monitoring timing is only on a predetermined time slot of a radio frame, radio subframe, or time slot group; while under a second preset condition, the monitoring timing is on any time slot of a radio frame, radio subframe, or time slot group.

[0240] The first preset scenario can be for all search spaces or for Type 1, Type 3, and user-specific search spaces (USS) configured for dedicated radio resource control (RRC).

[0241] The second preset case can be for all search spaces or for Type 1 cases for Type 0, 0A, 2 public search space CSS and non-dedicated RRC configurations.

[0242] In the first preset scenario, the monitoring timing (the timing when the UE performs PDCCH monitoring) can be limited to a predetermined time slot within a radio frame, radio subframe, or time slot group. That is, in the first preset scenario, the UE can only perform PDCCH monitoring within that predetermined time slot.

[0243] In the second preset scenario, the monitoring timing can be any time slot within a radio frame, radio subframe, or time slot group. That is, in the second preset scenario, the UE can perform PDCCH monitoring on any time slot within a radio frame, radio subframe, or time slot group.

[0244] The PDCCH monitoring processing device provided in this application determines whether to perform PDCCH monitoring on a predetermined time slot or any time slot of a radio frame, radio subframe, or time slot group based on different situations. Compared with the prior art, which mechanically defines PDCCH monitoring capabilities according to the granularity of each time slot or segment, it can effectively reduce the complexity of UE implementing PDCCH monitoring, thereby significantly improving communication efficiency and reducing UE power consumption, and has a very broad application prospect.

[0245] In one embodiment, under a first preset condition, the predetermined time slot includes any of the following:

[0246] The preset number of time slots preceding the wireless frame, wireless subframe, or time slot group;

[0247] The preset number of time slots following the wireless frame, wireless subframe, or time slot group;

[0248] The wireless frame, wireless subframe, or time slot group is a time slot with a preset number of time slots between each other.

[0249] The preset number can be, for example, 2 or 3, and its specific size can be adjusted according to actual needs. This application embodiment does not impose a specific limitation on this.

[0250] When the preset number is 2, the preset time slot can be the first 2 or the last 2 time slots of a radio frame, or the first 2 or the last 2 time slots of a radio subframe, or the first 2 or the last 2 time slots of a time slot group.

[0251] The number of preset time slots can be, for example, 4 or 5, and its specific size can be adjusted according to actual needs. This application does not impose a specific limitation on this.

[0252] When the preset number of time slots is 4, the preset time slots can be time slots that are every 4 time slots in a radio frame. For example, when the first preset time slot is the second time slot of a radio frame, the subsequent preset time slots (the second preset time slot, the third preset time slot, etc.) can be the 7th time slot, the 12th time slot, etc. of the radio frame. The preset time slots can also be time slots that are every 4 time slots in a radio subframe. For example, when the first preset time slot is the second time slot of a radio subframe, the subsequent preset time slots (the second preset time slot, the third preset time slot, etc.) can be the 7th time slot, the 12th time slot, etc. of the radio subframe. The preset time slots can also be time slots that are every 4 time slots in a time slot group. For example, when the first preset time slot is the second time slot of a time slot group, the subsequent preset time slots (the second preset time slot, the third preset time slot, etc.) can be the 7th time slot, the 12th time slot, etc. of the time slot group.

[0253] The processing apparatus for PDCCH monitoring capability provided in this application embodiment improves the flexibility of PDCCH monitoring because the predetermined time slot can be on multiple time slots of a radio frame, radio subframe, or time slot group.

[0254] In one embodiment, the PDCCH monitoring capability processing method provided in this application may further include:

[0255] Based on the PDCCH monitoring capability, SS is configured on the time slots that the UE can monitor.

[0256] It should be noted that after receiving the PDCCH monitoring capability, the network-side device can determine in which time slots the UE will perform PDCCH monitoring. Therefore, after receiving the PDCCH monitoring capability, the network-side device will configure SS for the UE in the time slots it can monitor, so that the UE can perform PDCCH monitoring.

[0257] It should be noted that the PDCCH monitoring capability processing method provided in this application embodiment can be executed by a PDCCH monitoring capability processing device, or by a control module within that PDCCH monitoring capability processing device for executing the PDCCH monitoring capability processing method. This application embodiment uses the execution of the PDCCH monitoring capability processing method by a PDCCH monitoring capability processing device as an example to illustrate the PDCCH monitoring capability processing device provided in this application embodiment.
