[0022] In order to make the technical solutions provided in the embodiments of the present application more fully understood, the following contents are introduced below.

[0023] 1. PDCCH monitoring capability definition for NR Release 15 (Rel-15)

[0024] In NR Rel-15, PDCCH monitoring capability is divided into mandatory capability and optional capability.

[0025] First, the capabilities of Mandatory without capability signaling are as follows:

[0026] Control-resource set (CORESET): Each BWP (Bandwidth Part) of each cell can be configured with another CORESET in addition to CORESET 0.

[0027] -Frequency range (FR) 1: 6 Resource Block (RB) bitmap + 1 to 3 symbols.

[0028] -FR2: For the Common Search Space (CSS) of Types 0, 0A, and 2 and Type 1 configured by non-dedicated Radio Resource Control (RRC), this is a 6RB bitmap + 1 to 3 symbols. For Type 1, Type 3, and USS configured by dedicated RRC, this is a 6RB bitmap + 1 to 2 symbols.

[0029] -Resource Element Group (REG) bundle size: 2 / 3 / 6.

[0030] - Mapping Control Channel Elements (CCEs) to REGs in an interleaved and non-interleaved manner.

[0031] Supports aligning upper layer parameter precoder granularity size with REG bundle size.

[0032] Supports demodulation reference signal (DM-RS) scrambling.

[0033] Supports configuring one or more Transmission Configuration Indication (TCI) states.

[0034] Unicast PDCCH transmission in CSS and USS (User Specific Search Space).

[0035] -Aggregation level (AL) 1, 2, 4, 8, 16.

[0036] For a scheduled Secondary Cell (SCell), there are a maximum of 3 Search Space (SS) sets in each slot (defined by the Scheduling Cell) of each BWP, and this restriction is enforced before SS dropping.

[0037] For Type 1, Type 3 and USS configured by dedicated RRC, the monitoring occasions are three symbols before a slot.

[0038] For Type 0, 0A, 2 CSS and Type 1 configured by non-dedicated RRC, the monitoring occasions may be in any one symbol of a slot, and may be within a single span of a slot, for example, three consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols.

[0039] -Supports monitoring of Downlink Control Information (DCI) 0_0, 0_1, 1_0, 1_1.

[0040] For Frequency Division Duplexing (FDD) systems, for each scheduled Component Carrier (CC), only one DCI for scheduling downlink (DL) unicast transmission and one DCI for scheduling uplink (UL) unicast transmission are processed in each slot.

[0041] For a Time Division Duplex (TDD) system, for each scheduled CC, in each slot, only one DCI scheduling DL unicast transmission and two DCIs scheduling UL unicast transmission are processed.

[0042] Next, the capabilities of Mandatory with capability signaling are as follows:

[0043] CORESET in FR2

[0044] For Type 1, Type 3 and USS configured by dedicated RRC, it is a 6RB bitmap + 3 symbols.

[0045] Finally, the optional abilities are:

[0046] PDCCH Monitoring Single Occasion

[0047] -FR1: Instructs the UE to support receiving a PDCCH scrambled with a Cell-Radio Network Temporary Identifier (C-RNTI) and a Configured Scheduling-Radio Network Temporary Identifier (CS-RNTI) in any three consecutive symbols of one 15 KHz slot.

[0048] PDCCH-Monitoring Any Occasions

[0049] -withoutDCI-gap: For Type 1, Type 3, and USS configured by dedicated RRC, the monitoring occasions are in any one symbol of one slot and satisfy the blind detection (Blind Decoding, BD) budget restriction.

[0050] -withDCI-gap: For Type 1, Type 3 and USS configured by dedicated RRC, the monolithic occasions are in any one symbol of one slot, but the gap between any two consecutive PDCCHs scrambled with C-RNTI, MCS-C-RNTI or CS-RNTI must satisfy the gap restriction, i.e., 2 symbols for 15KHz (2 symbols for 15KHz), 4 symbols for 30KHz (4 symbols for 30KHz), 7 symbols for (60KHz, NCP), 14 symbols for 120KHz (14 symbols for 120KHz), and satisfy the BD budget restriction.

[0051] PDCCH-Monitoring Any Occasions With SpanGap

[0052] - A span pattern is determined based on the (X, Y) values ​​of the UE reporting placed by the monitoring occasions of all SSs, 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 one of the slots, the span length is max{maximum value of all CORESET durations, minimum value of Y in the UE reported candidate value}, the length of the last span may be short, and the start position of the next span is the position of the first monitoring occasion that does not exist in the previous span.

[0053] -span Checks whether the pattern satisfies at least one reporting (X,Y) constraint.

[0054] 2. PDCCH monitoring capability definition in NR Rel-16

[0055] In NR Rel-16, all PDCCH monitoring capabilities are optional and are as follows:

[0056] 2.1. PDCCH-Monitoring-r16: Different from Rel15, it is possible to report the span value supported per SCS for each Physical Downlink Shared Channel (PDSCH) processing type, and each span satisfies the corresponding BD / CCE restrictions.

[0057] 2.2. PDCCH-MonitoringMixed-r16: Supports different serving cells to have different monitoring capability configurations.

[0058] 2.3. PDCCH-MonitoringCA-r16: UE report PDCCH-Monitoring-r16 specifies the maximum number of monitoring cells to be allocated when per span BD and CCE restrictions are implemented, and indicates whether the supporting span arrangement is aligned or not.

[0059] Hereinafter, a method for processing a PDCCH monitoring capability provided in an embodiment of the present application will be described in detail with reference to the drawings according to specific embodiments and application cases.

[0060] FIG. 2 is a schematic flow chart (part 1) of a method for processing a PDCCH monitoring capability provided in an embodiment of the present application. As shown in FIG. 2, an embodiment of the present application provides a method for processing a PDCCH monitoring capability, the method being applied to a terminal: A step S210 of determining a physical downlink control channel (PDCCH) monitoring capability representing a restriction condition that should be satisfied for a slot that the terminal UE can monitor; and a step S220 of transmitting a PDCCH monitoring capability; PDCCH monitoring capability is The monitoring timing is only in a predetermined slot of a radio frame, a radio subframe, or a slot group; The monitoring timing may be in any slot of a radio frame, a radio subframe, or a slot group, or any combination thereof.

[0061] It should be noted that the execution subject of the above method may be a terminal. Hereinafter, the technical solution of the present application will be described in detail by taking the above method executed by a terminal as an example.

[0062] First, the UE can determine its PDCCH monitoring capability, i.e., determine the constraints that the UE can monitor on the slots it can monitor.

[0063] After determining the PDCCH monitoring capability, the UE can send the PDCCH monitoring capability to the network, so that the network configures corresponding resources to the UE according to the PDCCH monitoring capability, for example, configures a corresponding PDCCH to the UE.

[0064] In one embodiment, in a first predetermined case, the monitoring timing is only in a predetermined slot of a radio frame, a radio subframe, or a slot group, and in a second predetermined case, the monitoring timing is in any slot of the radio frame, a radio subframe, or a slot group.

[0065] The first predefined case may be for all search spaces or may be for Type 1, Type 3 and user specific search spaces USS configured by dedicated radio resource control RRC.

[0066] The second predetermined case may be for all search spaces, or may be for common search space CSS of Types 0, 0A, 2 and Type 1 configured by non-dedicated RRC.

[0067] In the first predetermined case, the monitoring timing (the timing when the UE performs PDCCH monitoring) may be only in a predetermined slot of one radio frame or radio subframe or slot group, i.e., in the first predetermined case, the UE can monitor the PDCCH only in this predetermined slot.

[0068] In the second predetermined case, the monitoring timing may be in any slot of one radio frame, one radio subframe, or one slot group, that is, in the second predetermined case, the UE can monitor the PDCCH in any slot of one radio frame, one radio subframe, or one slot group.

[0069] In the PDCCH monitoring capability processing method provided in the embodiments of the present application, by determining to monitor PDCCH in a specified slot or any slot of a radio frame, radio subframe, or slot group according to different cases, the complexity of realizing PDCCH monitoring in a UE can be effectively reduced compared with the conventional technology that mechanically defines the PDCCH monitoring capability at a granularity of each slot or each span, thus obviously improving communication efficiency and reducing the power consumption of the UE, and is expected to be widely applied.

[0070] In one embodiment of the present application, the predetermined slot is: a first predetermined number of slots in a radio frame or radio subframe or slot group; the last predetermined number of slots in a radio frame or radio subframe or slot group; and This may include any one of the slots spaced apart by a predetermined number of slots in a radio frame or radio subframe or slot group.

[0071] Here, the predetermined number may be specifically, for example, 2, 3, etc., and the specific size can be adjusted according to actual requirements, and the embodiments of the present application are not specifically limited thereto.

[0072] When the predetermined number is two, the predetermined slots may be the first two or last two slots in a radio frame, or the first two or last two slots in a radio subframe, or the first two or last two slots in a slot group.

[0073] The specific number of the predetermined slots may be, for example, 4, 5, etc., and the specific size can be adjusted according to actual requirements, and the embodiments of the present application are not specifically limited thereto.

[0074] When the number of predetermined slots is 4, the predetermined slots may be slots spaced apart by 4 slots in a radio frame. For example, when a first predetermined slot is the second slot of a radio frame, the subsequent predetermined slots (the second predetermined slot, the third predetermined slot, ...) may be the seventh slot, the twelfth slot, ... of the radio frame. The predetermined slots may be slots spaced apart by 4 slots in a radio subframe. For example, when a first predetermined slot is the second slot of a radio subframe, the subsequent predetermined slots (the second predetermined slot, the third predetermined slot, ...) may be the seventh slot, the twelfth slot, ... of the radio subframe. The predetermined slots may be slots spaced apart by 4 slots in a slot group. For example, when a first predetermined slot is the second slot of a slot group, the subsequent predetermined slots (the second predetermined slot, the third predetermined slot, ...) may be the seventh slot, the twelfth slot, ... of the slot group.

[0075] In the method for processing the PDCCH monitoring capability provided in the embodiment of the present application, a certain slot may be located in multiple slots of a radio frame or a radio subframe or a slot group, which improves the flexibility of the implementation of PDCCH monitoring.

[0076] In one embodiment, the PDCCH monitoring capability is: In a first predetermined case, the monitoring timing is in a radio frame, a radio subframe, or an arbitrary slot of a slot group; The first predetermined case further includes any one of: the monitoring timing is in a radio frame, or a radio subframe, or an arbitrary slot of a slot group, and any consecutive PDCCHs satisfy a predetermined interval.

[0077] Here, the predetermined interval may be preset or may be determined according to the specific size of the SCS, for example, for a 480KHz SCS, the predetermined interval may be 4 slots, and for a 960KHz SCS, the predetermined interval may be 8 slots.

[0078] It should be noted that the PDCCH monitoring capability can be an optional capability of PDCCH monitoring, that is, when the UE has the PDCCH capability, it reports the capability to the network, and the network configures corresponding resources to the UE only when the UE reports the capability.

[0079] Meanwhile, the PDCCH monitoring capability described in the above embodiment (in the first predetermined case, the monitoring timing is only in a predetermined slot of a radio frame or a radio subframe or a slot group, and in the second predetermined case, the monitoring timing is in any slot of a radio frame or a radio subframe or a slot group) can be a mandatory capability of PDCCH monitoring, that is, the PDCCH monitoring capability can be defined by a protocol, and the UE needs to realize the PDCCH monitoring capability, and the network needs to configure the corresponding resource to the UE according to the monitoring capability.

[0080] Of course, the optional and mandatory capabilities of the PDCCH monitoring may be exchanged according to slot requirements.

[0081] For example, in one embodiment, the optional capability of the PDCCH monitoring (in a first predetermined case, the monitoring timing is in any slot of the radio frame or radio subframe or slot group, or in a predetermined case, the monitoring timing is in any slot of the radio frame or radio subframe or slot group, and any consecutive PDCCHs satisfy the predetermined interval) may be a mandatory capability that is compulsorily observed when the UE and the network actually perform PDCCH monitoring. The mandatory capability of the PDCCH monitoring (in a first predetermined case, the monitoring timing is only in a predetermined slot of the radio frame or radio subframe or slot group, and in a second predetermined case, the monitoring timing is in any slot of the radio frame or radio subframe or slot group) may be an optional capability that is selectably observed when the UE and the network actually perform PDCCH monitoring.

[0082] Of course, the optional and mandatory capabilities of PDCCH monitoring may be combined according to slot requirements.

[0083] For example, in one embodiment, all of the optional and mandatory capabilities for PDCCH monitoring may be mandatory capabilities that are compulsorily adhered to when the UE and the network actually perform PDCCH monitoring, or may be optional capabilities that are selectably adhered to when the UE and the network actually perform PDCCH monitoring.

[0084] In the method for processing the PDCCH monitoring capability provided in the embodiment of the present application, the PDCCH monitoring capability can be flexibly divided into Mandatory capability and Optional capability according to actual requirements, thereby further improving the flexibility of implementing PDCCH monitoring.

[0085] In one embodiment, the slot groups may be determined in the following manner.

[0086] To determine and understand the number of slots N or the set of slot numbers {Ni} included in a slot group, each slot group corresponds to one slot number N, and when there are multiple slot groups, there are multiple slot numbers N (N may be different values), and the multiple slot numbers N constitute the set of slot numbers {Ni}. Each element in the set of slot numbers {Ni} (the number of slots N of different slot groups) may be similar to each other or different from each other.

[0087] Based on the determined number of slots N or the set of slot numbers {Ni}, the position of the slot group is determined.

[0088] Optionally, the number of slots N or the set of slot numbers {Ni} may be obtained by one of the following methods 1 to 4.

[0089] Method 1: Obtained through network placement.

[0090] According to actual requirements, for example, according to the parameters of the data to be transmitted (size, frequency, etc.), the time domain resource occupancy status, etc., the network may allocate one slot number for each slot group, thereby determining the number of slots N (when there is only one slot group) or the set of slot numbers {Ni} (when there are multiple slot groups) contained in the slot group.

[0091] Method 2: The downlink control information (DCI) time domain scheduling parameter is obtained based on the number of schedulable physical downlink shared channels (PDSCHs) or the number of slots.

[0092] The network may determine the number of slots N according to the number of PDSCHs or slots that can be scheduled by the DCI time domain scheduling parameter, where the number of slots N may correspond one-to-one to the number of schedulable PDSCHs or slots, or may be proportional to the number of schedulable PDSCHs or slots, for example, the proportionality may be 2:1. For example, when the number of schedulable PDSCHs or slots is 4, the number of slots N may be 8.

[0093] The total number of schedulable PDSCHs or slots may be the number of slots included in different slot groups. Also, the maximum or minimum number of schedulable PDSCHs or slots according to the DCI time domain scheduling parameter may be the number of slots included in a slot group.

[0094] Manner 3: Obtain according to a capability parameter reported by a UE, which includes a slot number N or a slot number set {Ni}, or the DCI time-domain scheduling parameter includes the number of PDSCHs that can be scheduled or the number of slots.

[0095] The number of slots N or the set of slot numbers {Ni} may be determined according to a capability parameter reported by the UE to the network, where the capability parameter is a parameter related to the PDCCH monitoring capability of the UE.

[0096] The ability parameters may include a slot number N or a set of slot numbers {Ni}. When there are a plurality of slot numbers N, all of the slot numbers N may be the numbers of slots included in different slot groups, or the maximum, minimum, median, or average value of all of the slot numbers N may be the number of slots included in a slot group.

[0097] The capability parameter may further include the number of PDSCHs or the number of slots that can be scheduled by a DCI time-domain scheduling parameter. All values ​​of the number of PDSCHs or the number of slots that can be scheduled by one DCI time-domain scheduling parameter may be the number of slots included in different slot groups. Also, the maximum, minimum, median, or average value of the number of PDSCHs or the number of slots that can be scheduled by one DCI time-domain scheduling parameter may be the number of slots included in a slot group.

[0098] In one embodiment, the performance parameters include: The number of slots in the slot group, Gap values ​​between slots or slot groups, and It may further include one or more of the following parameters: a BD budget value or a CCE budget value.

[0099] Here, the BD budget value may be a budget value for the number of candidate PDCCHs (PDCCH Candidates) corresponding to a given slot, and the CCE budget value may be a budget value for the number of CCEs required for blind detection.

[0100] After receiving the capability parameters reported by the UE, the network configures corresponding resources for the UE according to the capability parameters, so that the UE monitors the PDCCH.

[0101] Method 4: Obtain using the number of slots N or the set of slot numbers {Ni} predefined in the protocol.

[0102] The UE and the network may further perform PDCCH monitoring or resource configuration, respectively, according to the slot number N or slot number set {Ni} predefined in the protocol according to relevant provisions of the protocol.

[0103] As can be understood, the number of slots N or the set of slot numbers {Ni} may be determined by further combining the above methods, provided that they do not violate each other. For example, the number of slots N or the set of slot numbers {Ni} may be determined by combining the maximum or minimum values ​​of the methods 2 and 3.

[0104] In the method for processing the PDCCH monitoring capability provided in the embodiment of the present application, the number of slots or the set of number of slots can be determined according to the above various manners, so that the possibility of realizing the PDCCH monitoring is improved.

[0105] In one embodiment, the location of the slot group may be determined according to one of the following schemes I to IV.

[0106] Method I: Determined by any N consecutive slots.

[0107] After determining the number of slots N or the set of slot numbers {Ni} of the slot group, the position of the slot group can be determined based on the determined number of slots N.

[0108] In Scheme I, the location of the slot group may be any of N consecutive slots. As shown in Fig. 4, when the number of slots is 4, the location of the slot group may be any of 4 consecutive slots in subframes Subframe#0 and Subframe#1, such as slot group 1, slot group 2, slot group 3, etc. in Fig. 3.

[0109] Method II: In a radio frame, radio subframe, or slot bundling, each N slots starting from the first slot is treated as a slot group, and the last group is treated as the last slot of the radio frame, radio subframe, or slot bundling, and the pattern of the slot group is repeated in each radio frame or radio subframe.

[0110] Here, a slot bundling is a unit having multiple consecutive slots, and the number of slots included in the slot bundling is equal to or greater than the number of slots included in the slot group.

[0111] Method III: A slot configured by the network or reported by the UE is taken as a start slot or a reference slot, and the position of the slot group is determined according to the start slot or the reference slot and the number of slots N.

[0112] In scheme III, a slot configured by the network or reported by the UE to the network may be taken as a starting slot or a reference slot, and the position of the slot group may be every N consecutive or non-consecutive slots from the starting slot or the reference slot.

[0113] Furthermore, the reference slot may be used as a reference point, and the slot group may be located every N consecutive or non-consecutive slots from a slot that is a predetermined number before or after the reference slot. For example, the slot group may be located every four consecutive slots from a slot that is two slots away from the reference slot, i.e., the third slot after the reference slot.

[0114] As shown in FIG. 4, the first slot, slot#0, in subframe, Subframe#0, may be set as the starting slot, and each of the four consecutive slots from slot#0 may be set as one slot group, for example, slot group 1, slot group 2, slot group 3, etc.

[0115] As shown in FIG. 5, one slot in subframe Subframe #0 may be set as a reference slot, and four consecutive slots from the reference slot may be set as one slot group, for example, slot group 1, slot group 2, slot group 3, etc.

[0116] Method IV: The pattern of the slot group is determined by the monitoring timing arranged by the search space SS.

[0117] Furthermore, the number of slots N in a slot group may be taken into account to determine the position of the slot group according to the monitoring timing configured by the SS. After the position of the slot group is determined, the pattern of the slot group in a radio frame, radio subframe, or slot bundling can be determined according to the position of each slot group.

[0118] In the method for processing the PDCCH monitoring capability provided in the embodiment of the present application, the position of the slot group is determined through the above various methods, so that the possibility of realizing the PDCCH monitoring can be further improved.

[0119] In one embodiment, determining a pattern of the slot group according to the monitoring timing arranged by the SS includes: The pattern of slot groups may be repeated in each radio frame or radio subframe or slot bundling. The starting point of the first slot group is the first slot with monitoring timing in a radio frame, radio subframe or slot bundling, and N slots from the starting point of the first slot group are considered to be the first slot group, the starting point of the next slot group is the first slot with monitoring timing that does not exist in any previous slot group, and N slots from the starting point of the next slot group are considered to be one slot group, and so on, until the last slot group ends at the end of the radio frame, radio subframe or slot bundling.

[0120] As shown in Fig. 6, dark colors represent monitoring timing. Slot group 1 is the first slot group in subframe Subframe#0, its start slot is the first slot (fourth slot) with monitoring timing in subframe Subframe#0, and four slots starting from this slot constitute slot group 1. Slot group 2 is the second slot group in subframe Subframe#0, its start slot is the first slot (16th slot) with monitoring timing that is not in slot group 1, and four slots starting from this slot constitute slot group 2.

[0121] Since the pattern of a slot group repeats in each radio frame or radio subframe or slot bundling, the pattern of the slot group in subframe Subframe#1 must match the pattern of the slot group in subframe Subframe#0, i.e., slot group 1' starts at the 4th slot in subframe Subframe#1 and the four slots starting from that slot make up slot group 1', slot group 2' starts at the 16th slot in subframe Subframe#1 and the four slots starting from that slot make up slot group 2',

[0122] In one embodiment, determining a pattern of the slot group according to the monitoring timing arranged by the SS includes: The pattern of the slot group may be different in each radio frame or radio subframe. For each radio frame, radio subframe or slot bundling, the start point of the first slot group is the first slot with monitoring timing in the radio frame, radio subframe or slot bundling, N slots from the start of the first slot group are considered to be the first slot group, the start of the next slot group is the first slot with monitoring timing that does not exist in any previous slot group, N slots from the start of the next slot group are considered to be one slot group, and so on until the last slot group ends at the end of the radio frame, radio subframe or slot bundling.

[0123] 7, dark colors represent monitoring timing. Slot group 1 is the first slot group in subframe Subframe#0, its starting point is the first slot with monitoring timing in subframe Subframe#0, and the four slots starting from this slot constitute slot group 1. Slot group 2 is the second slot group in subframe Subframe#0, its starting point is the first slot with monitoring timing that does not exist in slot group 1, and the four slots starting from this slot constitute slot group 2.

[0124] Slot group 3 is the first slot group in subframe Subframe #1, its starting point is the first slot with monitoring timing in subframe Subframe #1, and the four slots starting from that slot constitute slot group 3. Slot group 4 is the second slot group in subframe Subframe #1, its starting point is the first slot with monitoring timing that is not in slot group 3, and the four slots starting from that slot constitute slot group 4.

[0125] 7, in subframe Subframe#0, slot group 1 starts from the fourth slot, and slot group 2 starts from the sixteenth slot. In subframe Subframe#1, slot group 3 starts from the sixth slot, and slot group 4 starts from the sixteenth slot. Therefore, the slot group patterns are different between radio subframes Subframe#0 and Subframe#1.

[0126] In one embodiment, determining a pattern of the slot group according to the monitoring timing arranged by the SS includes: The method may include determining a pattern of a slot group from a start slot or a reference slot, the start slot being a slot configured by a network or reported by a UE, or determining a pattern of a slot group from a starting slot separated by a predetermined number of slots from the reference slot; The starting point of the first slot group is the start slot or the first slot with monitoring timing after the starting slot, N slots from the starting point of the first slot group are considered to be the first slot group, the starting point of the next slot group is the first slot with monitoring timing that does not exist in any previous slot group, and N slots from the starting point of the next slot group are considered to be one slot group, and the pattern of the slot groups is determined in this order.

[0175] First, the UE can determine its PDCCH monitoring capability, i.e., determine the constraints that the UE can monitor on the slots it can monitor.

[0176] After determining the PDCCH monitoring capability, the UE can send the PDCCH monitoring capability to a network side device.

[0177] The network side device receives the PDCCH monitoring capability sent by the UE, and configures corresponding resources to the UE according to the PDCCH monitoring capability, for example, configures a corresponding PDCCH to the UE.

[0178] After configuring the PDCCH, the network side device transmits the PDCCH to the UE, so that the UE monitors the PDCCH.

The predetermined slots may be slots spaced apart by 4 slots in a radio subframe. For example, when a first predetermined slot is the second slot of a radio subframe, the subsequent predetermined slots (the second predetermined slot, the third predetermined slot, ...) may be the seventh slot, the twelfth slot, ... of the radio subframe. The predetermined slots may be slots spaced apart by 4 slots in a slot group. For example, when a first predetermined slot is the second slot of a slot group, the subsequent predetermined slots (the second predetermined slot, the third predetermined slot, ...) may be the seventh slot, the twelfth slot, ... of the slot group.
