[0040] Referring to Figure 1 , Figure 1 is a flowchart of a physical downlink control channel PDCCH monitoring method provided by the embodiments of the present application. The physical downlink control channel PDCCH monitoring method provided by the embodiments of the present application can be applicable to a terminal device, and can specifically include the following steps:

[0041] Step S11, receiving at least one first downlink signaling, the at least one first downlink signaling including at least monitoring adaptation indication information used for indicating related information of a PDCCH monitoring skipping time interval corresponding to at least one search space set.

[0042] In some possible implementation manners, the terminal device can receive at least one first downlink signaling sent by the network device, and the at least one first downlink signaling received by the terminal device includes at least monitoring adaptation indication information used for indicating related information of a PDCCH monitoring skipping time interval corresponding to at least one search space set.

[0043] Optionally, the monitoring adaptation indication information included in each first downlink signaling can also be used to indicate switching of a search space set group.

[0044] As an example, each first downlink signaling received by the terminal device includes monitoring adaptation indication information, and each monitoring adaptation indication information is used for indicating at least related information of a PDCCH monitoring skipping time interval corresponding to at least one search space set.

[0045] The at least one first downlink signaling received by the terminal device can be the same signaling or different signaling, which is not limited herein.

[0046] Each monitoring adaptation indication information is used for indicating at least related information of a PDCCH monitoring skipping time interval corresponding to at least one search space set, that is, indicating related information of a PDCCH monitoring skipping time interval corresponding to PDCCH monitoring of the terminal device in the at least one search space set.

[0047] The related information of the PDCCH monitoring skipping time interval indicated by each monitoring adaptation indication information can be the same or different, which is not limited herein.

[0048] Step S12, determining at least one target PDCCH monitoring skipping time interval based on the monitoring adaptation indication information included in the at least one first downlink signaling.

[0049] In some possible implementation manners, when the at least one target PDCCH monitoring skipping time interval is determined based on the monitoring adaptation indication information included in the at least one first downlink signaling, the PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in each first downlink signaling can be determined, and the at least one target PDCCH monitoring skipping time interval can be determined from the PDCCH monitoring skipping time intervals corresponding to the at least one first downlink signaling.

[0050] Optionally, at least one target downlink signaling can be determined from the at least one first downlink signaling, and a PDCCH monitoring skip time interval corresponding to the listening adaptive indication information included in the at least one target downlink signaling is determined as a target PDCCH monitoring skip time interval.

[0051] It should be noted that the above manner of determining the at least one target PDCCH monitoring skip time interval is only an example, and the specific manner can be determined based on actual application scene requirements, which is not limited herein.

[0052] In step S13, in the case of PDCCH monitoring in the at least one target search space set, PDCCH monitoring is performed based on at least one target PDCCH monitoring skip time interval in the at least one target PDCCH monitoring skip time interval.

[0053] In some possible implementations, after the at least one target PDCCH monitoring skip time interval is determined, PDCCH monitoring can be performed in the target search space set based on each target PDCCH monitoring skip time interval.

[0054] In some possible implementations, in the case of determining one target PDCCH monitoring skip time interval, PDCCH monitoring can be performed in the at least one target search space set according to the target PDCCH monitoring skip time.

[0055] Optionally, in the case of determining a plurality of target PDCCH monitoring skip time intervals, PDCCH monitoring can be performed in one target search space set according to the target PDCCH monitoring skip time intervals.

[0056] For example, the arrangement order of the target PDCCH monitoring skip time intervals can be determined, and then PDCCH monitoring can be performed in one target search space set according to different target PDCCH monitoring skip time intervals in the arrangement order.

[0057] Alternatively, in the case of determining a plurality of target PDCCH monitoring skip time intervals, different target PDCCH monitoring skip time intervals can be PDCCH monitoring skip time intervals corresponding to PDCCH monitoring in different target search space sets. Thus, when PDCCH monitoring is performed in each target search space set, PDCCH monitoring is performed according to the corresponding target PDCCH monitoring skip time interval.

[0058] Each target search space set can be a search space set, and / or can be a search space set group (SSSG), and / or at least one search space set in a search space set group, and / or a set of search space sets in multiple search space sets in the case where a search space set group is not configured, without limitation.

[0059] In an optional embodiment, the at least one first downlink signaling received by the terminal device can be used for service transmission of different services. Specifically, a service identifier corresponding to each first downlink signaling configured by the network device can be used to indicate that the corresponding first downlink signaling is used for service transmission of different services.

[0060] The service corresponding to the at least one first downlink signaling can be an Ultra-Reliable and Low Latency Communications (URLLC) service, an Enhanced Mobile Broadband (eMBB) service, an extend reality (XR) service, or the like, but is not limited thereto.

[0061] The at least one first downlink signaling received by the terminal device can be a downlink control information (DCI). A service identifier corresponding to each DCI configured by the network device can be used to indicate that the corresponding DCI is used for service transmission of different services.

[0062] In an optional embodiment, the at least one first downlink signaling received by the terminal device can be different downlink signaling. Specifically, the at least one first downlink signaling includes at least one of the following:

[0063] at least one DCI carrying different information; or

[0064] at least one DCI with different DCI formats; or

[0065] at least one DCI associated with different parameter configurations of a search space set; or

[0066] at least one Medium Access Control (MAC) Control Element (CE); or

[0067] at least one Radio Resource Control (RRC) signaling.

[0068] The at least one first downlink signaling received by the terminal device can be one or more of a DCI, a MAC CE, or an RRC signaling, and when the at least one first downlink signaling received by the terminal device includes multiple DCIs, one or more of the following can be the same or different: the carrying information of each DCI, the DCI format, or the parameter configuration of the associated search space set.

[0069] As an example, the at least one first downlink signaling received by the terminal device is a DCI with different DCI formats, such as a DCI with different DCI format sizes, such as a DCI with DCI format x_1, DCI format x_2, or DCI format 2_x. Among them, DCI format x_1, DCI format x_2, or DCI format 2_x is a short name for a certain type of DCI, and x is an index value, such as DCI format x_1 being any one of DCI format 0_1 or DCI format 1_1 or DCI format 2_1.

[0070] Among them, the DCI with different DCI formats can also be a DCI with different Radio Network Tempory Identity (RNTI) cyclic redundancy check (CRC) scrambling.

[0071] Among them, the DCI with different carrying information can be a DCI signaling with different purposes, such as being indicated by a service identifier configured by the network to be used for service transmission of different services.

[0072] As an example, the terminal device receives two DCIs, and the service identifier configured by the network indicates that each DCI is used for service transmission of URLLC services and eMBB services, respectively.

[0073] Among them, the search space set associated with different parameter configurations can be one or more combinations of the following: a search space set associated with different types of search space sets, a search space set associated with different PDCCH monitoring periods, a search space set associated with different control resource sets (CORESETs), a search space set associated with different monitoring patterns, a search space set associated with different monitoring locations, or a search space set associated with different numbers of consecutive monitoring slots.

[0074] As an example, the terminal device receives DCI1 and DCI2, the DCI1 is configured in a common search space (CSS) (such as type3 CSS), and the DCI2 is configured in a user-specific search space (USS). The DCI formats of the DCI1 and the DCI2 can be the same or different, which is not limited herein.

[0075] If the terminal device receives multiple MAC CEs, the received multiple MAC CEs can be the same or different, which is not limited herein.

[0076] Similarly, if the terminal device receives multiple RRC signaling, the received multiple RRC signaling can be the same or different, which is not limited herein.

[0077] In an optional embodiment, the information related to the PDCCH monitoring skipping time interval indicated by each monitoring adaptation indication information includes at least one of the following:

[0078] A first time length, the first time length is used to indicate the PDCCH monitoring skipping time interval corresponding to at least one search space set; or

[0079] A multiple of a second time length, the second time length includes at least one search space set corresponding to the PDCCH monitoring period and / or the discontinuous reception (DRX) period and / or the specified time length of the terminal device performing PDCCH monitoring on the at least one search space set.

[0080] The first time length can be a fixed time length, such as a fixed time length in units of milliseconds or seconds, or a corresponding time length of a symbol, a subframe, or a radio frame, or other time lengths configured by a network device or defined by a protocol, which is not limited herein.

[0081] Alternatively, the value of the monitoring adaptation indication information included in each first downlink signaling can directly correspond to a PDCCH monitoring time interval configured by a network device, or correspond to an index value of a PDCCH monitoring skipping time interval configured by a network device, or correspond to a specific PDCCH monitoring skipping time interval defined by a protocol. That is, the monitoring adaptation indication information included in one first downlink signaling can directly indicate the PDCCH monitoring skipping time interval corresponding to at least one search space set.

[0082] The second time length can be a PDCCH monitoring period (DRX period) corresponding to at least one search space set when the terminal device performs PDCCH monitoring on the at least one search space set, and / or a network device configured or protocol specified specified time length, such as 2 ms or a certain time slot.

[0083] The multiple of the second time length can be an integer or a fraction, which is not limited here.

[0084] That is, the monitoring adaptation indication information included in one first downlink signaling can indirectly indicate the PDCCH monitoring skipping time interval corresponding to at least one search space set through the multiple of the second time length. The terminal device can determine the PDCCH monitoring skipping time interval corresponding to at least one search space set through the multiple of the second time length corresponding to the related information indicated by the monitoring adaptation indication information included in one first downlink signaling.

[0085] The PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in each first downlink signaling can be the same or different. For example, the monitoring adaptation indication information included in different first downlink signaling can correspond to the same first time length or multiple of the second time length, or can correspond to different first time length or multiple of the second time length, which is not limited here.

[0086] As an example, the terminal device receives three first downlink signaling, each of which includes monitoring adaptation indication information at least for indicating the related information of the PDCCH monitoring skipping time interval corresponding to at least one search space set. The multiple of the second time length included in the related information corresponding to the monitoring adaptation indication information included in each first downlink signaling is {1, 2, 4}, and the second time length is the PDCCH monitoring period corresponding to at least one search space set when the terminal device performs PDCCH monitoring on the at least one search space set. Then, the PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in each first downlink signaling is {1, 2, 4} * PDCCH monitoring period.

[0087] In an optional embodiment, based on the monitoring adaptation indication information included in at least one first downlink signaling, at least one target PDCCH monitoring skipping time interval is determined, including at least one of:

[0088] The PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in at least one first downlink signaling is determined as the target PDCCH monitoring skipping time interval; or

[0089] determine a first time interval satisfying a time interval condition as a target PDCCH monitoring skipping time interval, the time interval condition comprising at least one of a time interval maximum or a time interval minimum, and the first time interval comprising at least one of:

[0090] The at least one first downlink signaling comprises a PDCCH monitoring skipping time interval corresponding to monitoring adaptation indication information.

[0091] A minimum time interval K0min between a reception time of the PDCCH and a reception time of a physical downlink shared channel (PDSCH); or

[0092] A minimum time interval K1min between a reception time of the PDSCH and a reception time of a hybrid automatic repeat request-acknowledgement (HARQ-ACK); or

[0093] A minimum time interval K2min between a reception time of the PDCCH and a transmission time of a physical uplink shared channel (PUSCH); or

[0094] The at least one first downlink signaling comprises a PDCCH monitoring skipping time interval corresponding to monitoring adaptation indication information included in a second downlink signaling of the at least one first downlink signaling, and the third downlink signaling comprises at least one of:

[0095] A first received downlink signaling; or

[0096] A last received downlink signaling; or

[0097] A downlink signaling of a specified DCI format; or

[0098] A downlink signaling corresponding to a specified service; or

[0099] A downlink signaling associated with a specified configuration information; or

[0100] A downlink signaling satisfying a priority condition, the priority condition comprising a highest priority and / or a lowest priority.

[0101] The first downlink signaling can be indicated by a priority identifier of the network device.

[0102] The second downlink signaling can be a specified MAC CE and / or a high layer signaling.

[0103] As an example, the terminal device receives two DCIs, which are DCI of DCI format x_1 and DCI format x_2, and the PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in the DCI of DCI format x_1 and DCI format x_2 is T1 and T2 respectively. The terminal device can determine the PDCCH monitoring skipping time interval T1 and T2 as the target PDCCH monitoring skipping time interval.

[0104] As an example, the terminal device receives two DCIs, which are DCI of DCI format x_1 and DCI format x_2, and the PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in the DCI of DCI format x_1 and DCI format x_2 is T1 and T2 respectively. The terminal device can determine the PDCCH monitoring skipping time interval T1 and T2 as the target PDCCH monitoring skipping time interval.

[0105] As an example, the terminal device receives two DCIs, which are DCI of DCI format x_1 and DCI format x_2, and the PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in the DCI of DCI format x_1 and DCI format x_2 is T1 and T2 respectively. The terminal device can determine the PDCCH monitoring skipping time interval T1 and T2 as the target PDCCH monitoring skipping time interval.

[0106] As an example, the terminal device receives two DCIs including monitoring adaptation indication information at least for indicating PDCCH monitoring skipping time interval corresponding to at least one search space set, which are DCI of DCI format x_1 and DCI format x_2 respectively, and the PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in the DCI of DCI format x_1 and DCI format x_2 is T7 and T8 respectively. Wherein, the terminal device determines the signaling priority of the DCI of DCI format x_1 and DCI format x_2 through the priority identifier configured by the network device. The terminal device can determine the PDCCH monitoring skipping time interval T7 corresponding to the monitoring adaptation indication information included in the DCI with the highest priority as the target PDCCH monitoring skipping time interval, or determine the PDCCH monitoring skipping time interval T8 corresponding to the monitoring adaptation indication information included in the DCI with the lowest priority as the target PDCCH monitoring skipping time interval.

[0107] Wherein, the downlink signaling associated with the specified configuration information can be the downlink signaling associated with different PDCCH monitoring periods or other periodic behaviors, without limitation.

[0108] As an example, the terminal device receives two DCIs including monitoring adaptation indication information at least for indicating PDCCH monitoring skipping time interval corresponding to at least one search space set, which are DCI of DCI format x_1 and DCI format x_2 respectively, and the PDCCH monitoring period associated with the DCI of DCI format x_1 and DCI format x_2 is monitoring period 1 and monitoring period 2 respectively. The terminal device can determine the PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in the DCI associated with the PDCCH monitoring period with the longest period as the target PDCCH monitoring skipping time interval, or determine the PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information indicated by the corresponding information included in the DCI associated with the PDCCH monitoring period with the shortest period as the target PDCCH monitoring skipping time interval.

[0109] As an example, after determining the PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in the at least one first downlink signaling, the terminal device can determine the maximum time interval among the PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in the at least one first downlink signaling, and / or the minimum time interval K0min between the reception time of the PDCCH and the reception time of the PDSCH, and / or the minimum time interval K1min between the reception time of the PDSCH and the reception time of the HARQ-ACK, and / or the minimum time interval K2min between the reception time of the PDCCH and the transmission time of the PUSCH as the target PDCCH monitoring skipping time interval, or determine the minimum time interval among them as the target PDCCH monitoring skipping time interval, or determine the time interval among them within a preset time interval as the target PDCCH monitoring skipping time interval, or determine the time interval among them less than a preset threshold as the target PDCCH monitoring skipping time interval, or determine the time interval among them greater than a preset threshold as the target PDCCH skipping time interval, without limitation.

[0110] In an optional embodiment, the at least one target search space set can be a certain search space set, and / or can be a search space set group, and / or can be at least one search space set in the search space set group, and / or can be a search space set set among a plurality of search space sets in the case where a search space set group is not configured, without limitation.

[0111] Among them, at least one search space set in the search space set group or the search space set set among the search space sets in the case where a search space set group is not configured can be at least one search space set corresponding to a specified service.

[0112] Alternatively, a target search space set can be a search space set of a certain type, such as Type3CSS and / or USS, at least one search space set in a non-default SSSG, a non-dormant search space set group, or a non-empty search space set group, etc., without limitation.

[0138] In an optional embodiment, the monitoring adaptation indication information included in each first downlink signaling can also be used to indicate switching of a search space set group.

[0139] In an optional embodiment, after receiving the at least one first downlink signaling, the terminal device can receive first configuration information, determine the number of bits of the information field of the monitoring adaptation indication information included in each downlink signaling based on the first configuration information, and then determine the monitoring adaptation indication information included in the at least one first downlink signaling based on the number of bits of the information field of the monitoring adaptation indication information included in the at least one first downlink signaling.

[0140] The first configuration information is configured by the network device, and can be used to directly or indirectly indicate the number of bits of the information field of the monitoring adaptation indication information included in the at least one first downlink signaling.

[0141] In an optional embodiment, the first configuration information includes at least one of the following:

[0142] The first number of bits;

[0143] The first number of PDCCH monitoring skip time intervals corresponding to the at least one first downlink signaling and / or the second number of search space set groups configured by the network device.

[0144] The first number of bits is the number of bits of the information field of the monitoring adaptation indication information included in the at least one first downlink signaling, such as 0, 1, 2, etc., that is, the network device directly indicates the number of bits of the information field of the monitoring adaptation indication information included in the at least one first downlink signaling through the first number of bits in the first configuration information.

[0145] In a case where the first configuration information includes the first quantity of PDCCH monitoring skip time intervals corresponding to the at least one first downlink signaling and the second quantity of search space set groups configured by the network device, the terminal device can determine the quantity of information fields of the monitoring adaptation indication information included in the at least one first downlink signaling based on the first quantity and / or the second quantity, that is, the network device indirectly indicates the quantity of information fields of the monitoring adaptation indication information included in the at least one first downlink signaling through the first quantity and the second quantity in the first configuration information.

[0147]

[0148]

[0149] In a case where the first configuration information includes the first quantity of PDCCH monitoring skip time intervals corresponding to the at least one first downlink signaling and the second quantity of search space set groups configured by the network device, the terminal device can determine the quantity of information fields of the monitoring adaptation indication information included in the at least one first downlink signaling based on the first quantity and / or the second quantity, that is, the network device indirectly indicates the quantity of information fields of the monitoring adaptation indication information included in the at least one first downlink signaling through the first quantity and the second quantity in the first configuration information.

[0150] In a case where the network device does not configure a search space set group, that is, the first configuration information only includes the first quantity of PDCCH monitoring skip time intervals corresponding to the at least one first downlink signaling, the quantity of information fields of the monitoring adaptation indication information included in the at least one first downlink signaling can be represented as ceil(log2(M+1)). M is the first quantity of PDCCH monitoring skip time intervals corresponding to the at least one first downlink signaling, and M is greater than or equal to 1. It should be noted that the quantity of information fields of the monitoring adaptation indication information included in the at least one first downlink signaling can be determined based on the formula ceil(log2(M+1)), which is equivalent to but not limited to the result of the formula ceil(log2(M+1)).

[0151] When the terminal device is configured with the search space set group, and the first configuration information only includes the second quantity, the bit number of the information field of the monitoring adaptation indication information included in the at least one second downlink signaling can be represented as: ceil (log2 (N)). Wherein, ceil () is a rounding up function, N is the second quantity of the search space set group configured by the network device, and log2 () represents taking logarithm with 2 as the base. Wherein, N is greater than or equal to 1. It should be noted that the bit number of the information field of the monitoring adaptation indication information included in the at least one second downlink signaling described in the embodiment can be determined based on the formula ceil (log2 (N)), which means equivalent to but not limited to the result of the formula ceil (log2 (N)).

[0152] When the terminal device is configured with the search space set group, the bit number of the information field of the monitoring adaptation indication information included in the at least one first downlink signaling can be represented as: ceil (log2 (M+N)). Wherein, ceil () is a rounding up function, M is the first quantity of the PDCCH monitoring skipping time interval corresponding to the at least one first downlink signaling, M is greater than or equal to 0, N is the number of the search space set group configured by the network device, N is greater than or equal to 1, and log2 () represents taking logarithm with 2 as the base. It should be noted that the bit number of the information field of the monitoring adaptation indication information included in the at least one first downlink signaling described in the embodiment can be determined based on the formula ceil (log2 (M+N)), which means equivalent to but not limited to the result of the formula ceil (log2 (M+N)).

[0153] Referring to Figure 2 , Figure 2 is another flowchart of a physical downlink control channel (PDCCH) monitoring method provided by the embodiment of the present application. The physical downlink control channel (PDCCH) monitoring method provided by the embodiment of the present application can be applied to a network device, and can specifically include the following steps:

[0154] In step S21, at least one downlink signaling is sent, the at least one first downlink signaling includes monitoring adaptation indication information at least for indicating related information of a PDCCH monitoring skipping time interval corresponding to at least one search space set, and the at least one first downlink signaling is used to instruct the terminal device to determine at least one target PDCCH monitoring skipping time interval based on the monitoring adaptation indication information included in the at least one first downlink signaling, and in the case of PDCCH monitoring in at least one target search space set, perform PDCCH monitoring based on at least one target PDCCH monitoring skipping time interval in the at least one target PDCCH monitoring skipping time interval.

[0155] In an optional embodiment, the at least one first downlink signaling sent by the network device can be used for service transmission of different services, and specifically, a service identifier corresponding to each first downlink signaling can be configured to indicate that the corresponding first downlink signaling is used for service transmission of different services.

[0156] The service corresponding to the at least one first downlink signaling can be URLLC service or eMBB service or XR service, but is not limited thereto.

[0157] The at least one first downlink signaling sent by the network device can be DCI, and a service identifier corresponding to each DCI can be configured to indicate that the corresponding DCI is used for service transmission of different services.

[0158] In an optional embodiment, the at least one first downlink signaling received by the terminal device can be different downlink signalings. Specifically, the at least one first downlink signaling includes at least one of the following:

[0159] at least one DCI with different carrying information; or

[0160] at least one DCI with different DCI formats; or

[0161] at least one DCI associated with different parameter configurations of search space sets; or

[0162] at least one MAC CE; or

[0163] at least one RRC signaling.

[0164] That is, the at least one first downlink signaling sent by the network device can be one or more of DCI, MAC CE, or RRC signaling, and when the at least one first downlink signaling includes multiple DCIs, one or more of the carrying information of each DCI, the DCI format, or the parameter configuration of the associated search space set can be the same or different, which is not limited herein.

[0165] As an example, the at least one first downlink signaling sent by the network device is DCI with different DCI formats, such as DCI with different DCI format sizes, such as DCI with DCI format x_1, DCI format x_2, or DCI format 2_x. The DCI format x_1, DCI format x_2, or DCI format 2_x is a short name for a certain type of DCI, and x therein is an index value, such as DCI format x_1 being any one of DCI format 0_1, DCI format 1_1, or DCI format 2_1.

[0166] The DCI with different DCI formats can also be DCI with different RNTI scrambled CRC. The DCI carrying different information can be DCI signaling with different purposes, such as the service identifier configured by the network device can indicate that the DCI with different information is used for service transmission of different services.

[0167] As an example, the network device sends two DCIs, and the service identifier configured by the network indicates that each DCI is used for service transmission of URLLC service and eMBB service, respectively.

[0168] The search space set associated with different parameter configurations can be one or more combinations of the following: search space set associated with different types, search space set associated with different PDCCH monitoring periods, search space set associated with different control resource sets (CORESET), search space set associated with different monitoring patterns, search space set associated with different monitoring positions, or search space set associated with different numbers of consecutive monitoring slots, without limitation.

[0169] As an example, the network device sends DCI of DCI format x_1 and DCI format x_2, and the DCI of DCI format x_1 and DCI format x_2 is used for URLLC service transmission and eMBB service transmission, respectively, and the DCI of DCI format x_1 and DCI format x_2 includes monitoring adaptation indication information for indicating related information of PDCCH monitoring skipping time interval.

[0170] As an example, the network device sends DCI1 and DCI2, DCI1 is configured in CSS (such as type3CSS), and DCI2 is configured in USS. The DCI formats of DCI1 and DCI2 can be the same or different, without limitation. If the network device sends multiple MAC CEs, the multiple MAC CEs can be the same or different, without limitation.

[0171] Similarly, if the network device sends multiple RRC signaling, the multiple RRC signaling can be the same or different, without limitation.

[0172] In an optional embodiment, the related information of the PDCCH monitoring skipping time interval indicated by each monitoring adaptation indication information includes at least one of the following:

[0173] A first duration, the first duration is used to indicate the PDCCH monitoring skipping time interval corresponding to at least one search space set; or

[0174] A multiple of a second duration, the second duration includes at least one search space set corresponding to the PDCCH monitoring period and / or the period of DRX and / or the specified duration when the terminal device performs PDCCH monitoring on the at least one search space set.

[0175] The first time length can be a fixed time length, for example, the first time length can be a fixed time length in units of milliseconds or seconds, or a corresponding time length of a symbol, a subframe, or a radio frame, or other time length configured by a network device or agreed by a protocol, which is not limited herein.

[0176] Alternatively, the value of the monitoring adaptation indication information included in each first downlink signaling can directly correspond to a PDCCH monitoring time interval configured by a network device, or an index value of a PDCCH monitoring skipping time interval configured by a network device, or a specific PDCCH monitoring skipping time interval defined by a protocol. That is, the monitoring adaptation indication information included in one first downlink signaling can directly indicate the PDCCH monitoring skipping time interval corresponding to at least one search space set.

[0177] The second time length can be at least one search space set corresponding PDCCH monitoring period and / or DRX period and / or PDCCH monitoring period when the terminal device performs PDCCH monitoring in the at least one search space set, or a specified time length configured by a network device or agreed by a protocol, for example, the second time length can be 2 ms, or a certain time slot, etc.

[0178] The multiple of the second time length can be an integer (such as L), or a fraction (1 / L), which is not limited herein.

[0179] That is, the monitoring adaptation indication information included in one first downlink signaling can indirectly indicate the PDCCH monitoring skipping time interval corresponding to at least one search space set through the multiple of the second time length. The terminal device can determine the PDCCH monitoring skipping time interval corresponding to at least one search space set through the multiple of the second time length corresponding to the related information indicated by the monitoring adaptation indication information included in one first downlink signaling.

[0180] The PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in each first downlink signaling can be the same or different. For example, the monitoring adaptation indication information included in different first downlink signaling can correspond to the same first time length or multiple of the second time length, or can correspond to different first time length or multiple of the second time length, which is not limited herein.

[0181] As an example, the network device sends 3 first downlink signaling including the monitoring adaptation indication information related to at least indicating the PDCCH monitoring skipping time interval corresponding to at least one search space set, each first downlink signaling includes monitoring adaptation indication information corresponding to the second duration included in the related information, and the multiple of the second duration is {1, 1 / 2, 1 / 4}, and the second duration is the PDCCH monitoring period corresponding to at least one search space set when the terminal device performs PDCCH monitoring on at least one search space set. Then the PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in each first downlink signaling is {1, 1 / 2, 1 / 4} * the PDCCH monitoring period of the search space set where or associated with the corresponding first downlink signaling.

[0182] Wherein, if the protocol requires the same monitoring adaptation indication information to be carried between at least one downlink signaling in the same time slot, the same BWP or the same search space set group, the related information indicated by the monitoring adaptation indication information included in each first downlink signaling sent by the network device indicates the same PDCCH monitoring time interval.

[0183] In an optional embodiment, the at least one target search space set can be a certain search space set, and / or can be a search space set group, and / or can be at least one search space set in the search space set group, and / or can be a search space set set in multiple search space sets without configuring a search space set group, without limitation. Wherein, the at least one search space set in the search space set group or the search space set set in the multiple search space sets without configuring a search space set group can be at least one search space set corresponding to a specified service.

[0184] Alternatively, one target search space set can be a certain type of search space set, such as Type3CSS and / or USS, at least one search space set in a non-default SSSG, a non-dormant search space set group, or a non-empty search space set group, without limitation.

[0185] Optionally, the network device can indicate the PDCCH monitoring skipping time interval corresponding to a certain search space set in a specified BWP, or a search space set group, or at least one search space set in the search space set group, or a search space set set in multiple search space sets without configuring a search space set group, through the related information indicated by the monitoring adaptation indication information included in at least one first downlink signaling.

[0186] Wherein, the specified BWP can be at least one of a non-default BWP, a default BWP, a dormant BWP, a non-dormant BWP, or a current BWP.

[0187] The specified BWP corresponding to different first downlink signaling can be the same or different, and when the specified BWP corresponding to different downlink signaling is the same, the search space set, or the search space set group, or at least one search space set in the search space set group, or the search space set set in each search space set when no search space set group is configured, indicated by the related information corresponding to different first downlink signaling can be the same or different, which is not limited here.

[0188] Optionally, the network device can indicate the PDCCH monitoring skip time interval corresponding to the specified search space set group or at least one search space set in the specified search space set group, or the search space set set in each search space set when no search space set group is configured, through the related information indicated by the monitoring adaptation indication information included in each first downlink signaling.

[0189] The specified search space set group can be at least one of a non-default search space set group, a default search space set group, or any search space set group.

[0190] The specified search space set group corresponding to different first downlink signaling can be the same or different, which is not limited here.

[0191] Optionally, the network device can indicate the PDCCH monitoring skip time interval corresponding to the search space set group, the search space set set, the search space set, or at least one search space in the search space set group corresponding to the first downlink signaling, or the search space set group, the search space set set, the search space set, or at least one search space in the search space set group associated with the first downlink signaling, through the related information indicated by the monitoring adaptation indication information included in each first downlink signaling.

[0192] The search space set group, the search space set set, the search space set, or at least one search space set in the search space set group where the first downlink signaling is located can be the specified BWP or the current BWP or the specified search space set group or the current search space set group, or at least one search space set in the search space set group, the search space set set, the search space set, or the search space set group where the first downlink signaling is located, which is not limited here.

[0193] At least one of the search space set group, the search space set group set, the search space set, or the at least one search space set in the search space set group associated with the first downlink signaling can be at least one search space set in which all downlink signaling having the same DCI format as the corresponding first downlink signaling is located within a specified BWP or a current BWP or a specified search space set group or a current search space set group, or at least one search space set in which all downlink signaling having a DCI format belonging to the same category as the corresponding first downlink signaling is located within a specified BWP or a current BWP or a specified search space set group or a current search space set group, and this is not limited herein.

[0194] As an example, the DCI format of a certain first downlink signaling sent by the network device is DCI format x_1, and the monitoring adaptation indication information included in the downlink signaling is used to indicate a PDCCH monitoring skipping time interval corresponding to at least one search space set in which all downlink signaling having the same DCI format as the DCI format x_1 is located within a current BWP and / or a current search space set group.

[0195] Optionally, the network device can indicate, through different first downlink signaling, a PDCCH monitoring skipping time interval corresponding to at least one search space set corresponding to different services.

[0196] For time-sensitive services, configuring a small-grained PDCCH monitoring skipping time interval can make the terminal device more flexible when performing PDCCH monitoring on the corresponding search space set. For time-insensitive or burst services, configuring a PDCCH monitoring skipping time interval with a larger granularity, such as configuring a PDCCH monitoring period corresponding to the search space set or N times of a certain specified time length, can save signaling overhead.

[0197] Optionally, the network device can indicate, through different first downlink signaling, a PDCCH monitoring skipping time interval corresponding to at least one search space set associated with different control resource sets, or indicate, through different first downlink signaling, different PDCCH monitoring skipping time intervals corresponding to at least one search space set associated with the same control resource set.

[0198] Optionally, the network device can indicate, through different first downlink signaling, different PDCCH monitoring skipping time intervals corresponding to at least one search space set in a search space set group, a search space set collection, a search space set, or a search space set group specified by the MAC CE.

[0199] Optionally, the network device can indicate, through different first downlink signaling, different PDCCH monitoring skipping time intervals corresponding to at least one search space set in a search space set group, a search space set collection, a search space set, or a search space set group specified by the high-layer signaling.

[0200] Optionally, the network device can indicate, through different first downlink signaling, different PDCCH monitoring skipping time intervals corresponding to at least one search space set in a search space set group, a search space set collection, a search space set, or a search space set group specified by the high-layer signaling.

[0202] Optionally, the network device can indicate, through different first downlink signaling, PDCCH monitoring skipping time intervals corresponding to at least one search space set in a specified search space set group in a case where the terminal device performs PDCCH monitoring in a non-default search space set group.

[0203] Optionally, the network device can indicate, through different first downlink signaling, different PDCCH monitoring skipping time intervals corresponding to at least one search space set in a search space set group, a search space set collection, a search space set, or a search space set group corresponding to the search space set group, the search space set collection, the search space set, or the at least one search space set in which the terminal device currently performs PDCCH monitoring.

[0204] In an optional embodiment, the target search space set includes at least one of the following:

[0205] The at least one target search space set includes at least one of the following:

[0206] The at least one search space set in a search space set group, a search space set collection, a search space set, or a search space set group specified by the MAC CE; or

[0213] at least one search space set in the search space set group, the search space set group, the search space set group, or the search space set group; or

[0214] at least one search space set in the search space set group, the search space set group, the search space set group, or the search space set group; or

[0215] The third downlink signaling includes at least one of the following:

The target search space set group can also be a certain type of search space set or all search space sets within the specified BWP bandwidth part, which is not limited here.

The at least one target search space set group can also be a certain type of search space set or all search space sets within the specified BWP bandwidth part, which is not limited herein.

[0223] As an example, at least one search space set in the search space set group corresponding to the specified BWP or a certain search space set set in each search space set in the case where no search space set group is configured or multiple search space sets corresponding to the specified service or the specified type in all search space sets in the specified BWP can be one or more target search space sets.

[0225] The at least one search space set in the specified search space set group can be at least one search space set in the specified search space set group in the case where the terminal device performs PDCCH monitoring in a non-default search space set group.

[0226] At least one search space set group, search space set group set, search space set, or at least one search space set in the search space set group, search space set group set, search space set, or search space set group in which the third downlink signaling in the at least one first downlink signaling is located can be specified BWP or current BWP or specified search space set group or current search space set group, and this is not limited.

[0228] The third downlink signaling can be all downlink signaling in the first downlink signaling, or part of the downlink signaling in the first downlink signaling, or the first received downlink signaling and / or the last received downlink signaling and / or the downlink signaling of the specified DCI format and / or the downlink signaling corresponding to the specified service and / or the downlink signaling associated with the specified configuration information and / or the downlink signaling satisfying the priority condition in the first downlink signaling, and this is not limited.

[0229] As an example, the at least one target search space set is at least one search space set group, search space set group set, search space set, or search space set group in which all DCI having the same DCI format x_1 is located in the current BWP and / or the current search space set group.

[0230] In an optional embodiment, the monitoring adaptation indication information included in each first downlink signaling can also be used to indicate switching of a search space set group.

[0231] In an optional embodiment, after sending the at least one first downlink signaling, the network device can send first configuration information to the terminal device, so that the terminal device determines the bit number of the information field of the listening adaptation indication information included in the at least one first downlink signaling based on the first configuration information, and then determines the listening adaptation indication information included in the at least one first downlink signaling based on the bit number of the information field of the listening adaptation indication information included in the at least one first downlink signaling.

[0232] The first configuration information is configured by the network device and can be used to directly or indirectly indicate the bit number of the information field of the listening adaptation indication information included in the at least one first downlink signaling.

[0233] In an optional embodiment, the first configuration information includes at least one of the following:

[0234] The first bit number;

[0235] The first number of PDCCH listening skip time intervals corresponding to the at least one first downlink signaling and / or the second number of search space set groups configured by the network device.

[0236] The first bit number is the bit number of the information field of the listening adaptation indication information included in the at least one second downlink signaling, which can be 0, 1, 2, etc., that is, the network device directly indicates the bit number of the information field of the listening adaptation indication information included in the at least one first downlink signaling through the first bit number in the first configuration information.

[0237] The terminal device can determine the bit number of the information field of the listening adaptation indication information included in the at least one first downlink signaling based on the first number and / or the second number, that is, the network device indirectly indicates the bit number of the information field of the listening adaptation indication information included in the at least one first downlink signaling through the first number and the second number in the first configuration information.

[0238] In the prior art, the network device instructs the terminal device to perform PDCCH monitoring through DCI of DCI format x_1 and / or DCI format x_2, while the present application can instruct the terminal device to perform PDCCH monitoring in different target search space sets based on different target PDCCH monitoring skip time intervals based on downlink signaling of multiple DCI formats including DCI format x_1 and / or DCI format x_2 and / or RRC signaling and / or MAC CE and / or DCI carrying different information and / or DCI associated with different configuration parameters of search space sets. And the present application can instruct the terminal device to perform PDCCH monitoring in the corresponding target search space and according to the target PDCCH monitoring skip time interval corresponding to each target search space set through downlink signaling for different service transmission or with different purposes, so that the terminal device skips PDCCH monitoring opportunities with different target PDCCH monitoring skip time intervals when performing PDCCH monitoring in the corresponding target search space set for different services, and realizes adaptive monitoring of service differentiation.

[0239] If different downlink signaling needs to remain the same, such as each DCI in the same time slot needs to include the same monitoring adaptation indication information, in this case, when the terminal device has different service transmission, the network device can indicate the terminal device to perform PDCCH monitoring in the search space set corresponding to different services according to different PDCCH monitoring skip time intervals based on the same monitoring adaptation indication information included in each DCI, so as to distinguish the monitoring adaptation behavior of the terminal device for different services, and make the terminal device realize adaptive monitoring of service differentiation.

[0240] The PDCCH monitoring method provided by the embodiment of the present application will be further described below in combination with specific examples.

[0241] Example one:

[0242] The network device sends two DCIs including monitoring adaptation indication information at least for indicating the PDCCH monitoring skip time interval corresponding to at least one search space set, which are DCI of DCI format x_1 and DCI format x_2, and the terminal device determines that the PDCCH monitoring skip time intervals corresponding to the monitoring adaptation indication information included in each DCI are T1 and T2, then the PDCCH monitoring skip time intervals T1 and T2 can be determined as the target PDCCH monitoring skip time interval.

[0243] Further, the terminal device can perform PDCCH monitoring in at least one search space set in the search space set group, the search space set group set, the search space set, or the search space set group corresponding to or associated with the DCI based on the PDCCH monitoring skipping time interval T1 and T2, i.e., skip the corresponding PDCCH monitoring opportunity on at least one search space set in the search space set group, the search space set group set, the search space set, or the search space set group corresponding to or associated with the DCI based on the PDCCH monitoring skipping time interval T1 and T2.

The terminal device first receives the DCI of DCI format x_1, and determines that the PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in the DCI is T3. Before the monitoring adaptation behavior application time point (such as the next time slot), the terminal device receives the DCI of DCI format x_2 again, and determines that the PDCCH monitoring skipping time interval corresponding to the monitoring adaptation indication information included in the DCI is T4.

[0247] Alternatively, the terminal device can determine the PDCCH monitoring skipping time interval T4 corresponding to the monitoring adaptation indication information included in the last received DCI as the target PDCCH monitoring skipping time interval, and perform PDCCH monitoring in at least one search space set in the search space set group, the search space set group set, the search space set, or the search space set group corresponding to or associated with the DCI based on T4, i.e., skip the corresponding PDCCH monitoring opportunity on at least one search space set in the search space set group, the search space set group set, the search space set, or the search space set group corresponding to or associated with the DCI based on the PDCCH monitoring skipping time interval T4.

[0248] Alternatively, after determining T3 or T4 as the target PDCCH monitoring skipping time interval, the terminal device performs PDCCH monitoring in at least one search space set in the search space set group, search space set group set, search space set or search space set group associated with the DCI format x_1 and DCI format x_2 DCI based on the target PDCCH monitoring skipping time interval, that is, skips the corresponding PDCCH monitoring opportunity in at least one search space set in the search space set group, search space set group set, search space set or search space set group associated with the DCI based on the target PDCCH monitoring skipping time interval.
