Referring to fig. 1, fig. 1 is a flow chart of a method for monitoring a PDCCH of a physical downlink control channel according to an embodiment of the present application. The physical downlink control channel PDCCH monitoring method provided by the embodiment of the present application may be applicable to a terminal device, and specifically may include the following steps:

step S11, receiving at least one first downlink signaling, where the at least one first downlink signaling includes at least monitoring adaptive indication information for indicating relevant information of a PDCCH monitoring skip time interval corresponding to the at least one search space set.

In some possible embodiments, the terminal device may receive at least one first downlink signaling sent by the network device, where the at least one first downlink signaling received by the terminal device includes monitoring adaptive indication information at least for indicating related information of a PDCCH monitoring skip time interval corresponding to the at least one search space set.

Optionally, the listening adaptation indicating information included in each first downlink signaling may also be used to indicate a handover of the search space set group.

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

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

Each monitoring adaptive indication information is used for indicating the related information of the PDCCH monitoring skip time interval corresponding to at least one search space set, namely the related information of the PDCCH monitoring skip time interval corresponding to the terminal equipment when the at least one search space set monitors the PDCCH.

The information about the PDCCH monitoring skip time interval indicated by each monitoring adaptive indication information may be the same or different, which is not limited herein.

Step S12, determining at least one target PDCCH monitoring skip time interval based on monitoring adaptive indication information included in at least one first downlink signaling.

In some possible embodiments, when determining at least one target PDCCH monitoring skip time interval based on monitoring adaptive indication information included in at least one first downlink signaling, a PDCCH monitoring skip time interval corresponding to the monitoring adaptive indication information included in each first downlink signaling may be determined, and at least one target PDCCH monitoring skip time interval is determined from the PDCCH monitoring skip time intervals corresponding to each first downlink signaling.

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

It should be noted that, the above manner of determining the at least one target PDCCH monitoring skip time interval is merely an example, and may be specifically determined based on actual application scenario requirements, which is not limited herein.

Step S13, under the condition that the at least one target search space set monitors the PDCCH, the PDCCH is monitored based on at least one target PDCCH monitoring skip time interval in the at least one target PDCCH monitoring skip time interval.

In some possible embodiments, after determining at least one target PDCCH monitoring skip time interval, PDCCH monitoring may be performed in the target search space set on a per target PDCCH monitoring skip time interval basis.

In some possible embodiments, in the case that one target PDCCH monitoring skip time interval is determined, PDCCH monitoring may be performed in at least one target search space set according to the target PDCCH monitoring skip time.

Alternatively, in the case that a plurality of target PDCCH monitoring skip time intervals are determined, PDCCH monitoring may be performed in one target search space set according to each target PDCCH monitoring skip time interval.

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

Or, in the case that a plurality of target PDCCH monitoring skip time intervals are determined, different target PDCCH monitoring skip time intervals may be PDCCH monitoring skip time intervals corresponding to when PDCCH monitoring is performed in different target search space sets. And when the PDCCH monitoring is carried out on each target search space set, the PDCCH monitoring is carried out according to the corresponding target PDCCH monitoring skip time interval.

Wherein each target set of search spaces may be a certain set of search spaces, and/or may be a set of sets of search spaces (Search Space Set Group, SSSG), and/or at least one set of search spaces in a set of sets of search spaces, and/or a set of sets of search spaces in a plurality of sets of search spaces without configuring a set of sets of search spaces, without limitation.

In an optional embodiment, at least one first downlink signaling received by the terminal device may be used for service transmission of different services, and specifically, the service identifier configured by the network device and corresponding to each first downlink signaling may indicate that the corresponding first downlink signaling is used for service transmission of different services.

The service corresponding to the at least one first downlink signaling may be, but not limited to, ultra-Reliable and Low Latency Communications, URLLC, enhanced Mobile Broadband, eMBB, or extended reality (XR) service.

The at least one first downlink signaling received by the terminal device may be downlink control information (Downlink Control Information, DCI), and the service identifier configured by the network device and corresponding to each DCI indicates that the corresponding DCI is used for service transmission of different services.

In an alternative embodiment, the at least one first downlink signaling received by the terminal device may be a different downlink signaling. Specifically, the at least one first downlink signaling comprises at least one of:

at least one DCI with different bearer information; or (b)

At least one DCI of different DCI formats; or (b)

At least one DCI associating parameter configurations for different search space sets; or (b)

At least one media access Control (Medium Access Control, MAC) Control Element (CE); or (b)

At least one radio resource control (Radio Resource Control, RRC) signaling.

That is, when the at least one first downlink signaling received by the terminal device may be one or more of DCI, MAC CE, or RRC signaling, and the at least one first downlink signaling received by the terminal device includes multiple DCIs, one or more of bearer information, DCI format, or parameter configuration of the associated search space set of each DCI may be the same or different, which is not limited herein.

As an example, the at least one first downlink signaling received by the terminal device is DCI with a different DCI format, for example, may be DCI with a different DCI format size, for example, DCI format x_1, DCI format x_2 or DCI format 2_x. Where DCI format x_1, DCI format x_2, or DCI format 2_x is abbreviated for a certain type of DCI, where x is an index value, e.g., DCI format x_1 is any one of DCI format 0_1, DCI format 1_1, or DCI format 2_1.

The DCI with different DCI formats may also be DCI with different radio network temporary identities (Radio Network Tempory Identity, RNTI) scrambled by cyclic redundancy check (Cyclic Redundancy Check, CRC).

The DCI with different bearer information may be DCI signaling with different purposes, for example, a service identifier configured by a network device indicates that the DCI with different bearer information is used for service transmission of different services.

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 the URLLC service and the eMBB service respectively.

The set of search spaces associated with different parameter configurations may be one or more combinations of sets of search spaces associated with different types of sets of search spaces, sets of search spaces associated with different PDCCH listening periods, sets of search spaces associated with different listening patterns, sets of search spaces associated with different listening positions, or sets of search spaces associated with different numbers of slots for continuous listening, which is not limited herein.

As an example, the terminal device receives DCI1 and DCI2, DCI1 is configured in a common search space (Common Search Space, CSS) (e.g. type3 CSS), and DCI2 is configured in a user-specific search space (UE-Specific Search Space, USS). The DCI formats of DCI1 and DCI2 may be the same or different, and are not limited herein.

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

Similarly, if the terminal device receives multiple RRC signaling, the multiple received RRC signaling may be the same or different, and the method is not limited herein.

In an alternative embodiment, the information about the PDCCH listening skip time interval indicated by each listening adaptation indicating information includes at least one of:

the first time length is used for indicating a PDCCH monitoring skip time interval corresponding to at least one search space set; or (b)

And the second time length comprises a PDCCH monitoring period and/or a discontinuous reception (Discontinuous Reception, DRX) period and/or a designated time length corresponding to at least one search space set when the terminal equipment monitors the PDCCH.

The first duration may be a fixed duration, for example, the first duration may be a fixed duration in milliseconds or seconds, or may be a duration corresponding to a symbol, a subframe, or a radio frame, or may be other durations configured or agreed by a network device, which is not limited herein.

Or, the value of the monitoring adaptive indication information included in each first downlink signaling may directly correspond to a PDCCH monitoring time interval configured by a network device, or corresponds to an index value of a PDCCH monitoring skip time interval configured by a network device, or corresponds to a PDCCH monitoring skip time interval defined by a specific protocol. That is, the monitoring adaptive indication information included in the first downlink signaling may directly indicate the PDCCH monitoring skip time interval corresponding to the at least one search space set.

The second duration may be a specified duration agreed by the network device or a protocol, for example, the second duration may be 2ms, or a certain time slot, or the like, in addition to the PDCCH listening period DRX period and/or the PDCCH listening period corresponding to at least one search space set corresponding to the terminal device when the terminal device performs PDCCH listening in at least one search space set.

The multiple of the second duration may be an integer or a fraction, which is not limited herein.

That is, the monitoring adaptive indication information included in the first downlink signaling may indirectly indicate the PDCCH monitoring skip time interval corresponding to the at least one search space set through a multiple of the second duration. The terminal device may determine, by using a multiple of a second duration corresponding to the relevant information indicated by the monitoring adaptive indication information included in the first downlink signaling, a PDCCH monitoring skip time interval corresponding to the at least one search space set.

The PDCCH monitoring skip time intervals corresponding to the monitoring adaptive indication information included in each first downlink signaling may be the same or different. The monitoring adaptive indication information included in the different first downlink signaling may correspond to a multiple of the same first duration or second duration, or may correspond to a multiple of the different first duration or second duration, which is not limited herein.

As an example, the terminal device receives 3 first downlink signaling, where each first downlink signaling includes monitoring adaptive indication information at least for indicating relevant information of a PDCCH monitoring skip time interval corresponding to at least one search space set, the second duration included in relevant information corresponding to the monitoring adaptive indication information included in each first downlink signaling is multiple {1,2,4}, and the second duration is a PDCCH monitoring period corresponding to at least one search space set corresponding to when the terminal device monitors the PDCCH in the at least one search space set. The PDCCH monitoring skip time interval corresponding to the monitoring adaptive indication information included in each first downlink signaling is {1,2,4 }. PDCCH monitoring period.

In an alternative embodiment, based on the listening adaptation indication information included in the at least one first downlink signaling, determining at least one target PDCCH listening skip time interval includes at least one of:

Determining a PDCCH monitoring skip time interval corresponding to monitoring self-adaptive indication information included in at least one first downlink signaling as a target PDCCH monitoring skip time interval; or (b)

Determining a first time interval satisfying a time interval condition as a target PDCCH monitoring skip time interval, the time interval condition including at least one of a maximum time interval or a minimum time interval, the first time interval including at least one of:

the PDCCH monitoring skip time interval corresponding to the monitoring self-adaptive indication information is included in at least one first downlink signaling; or (b)

A minimum time interval K0min between the reception time of the PDCCH and the reception time of the physical downlink shared channel (Physical Downlink Share Channel, PDSCH); or (b)

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

A minimum time interval K2min between the reception time of the PDCCH and the transmission time of the physical uplink shared channel (Physical Uplink Share Channel, PUSCH); or (b)

Determining a PDCCH monitoring skip interval corresponding to monitoring adaptive indication information included in a second downlink signaling in at least one first downlink signaling as a target PDCCH monitoring skip time interval, wherein the third downlink signaling comprises at least one of the following:

The first received downlink signaling; or (b)

The last received downlink signaling; or (b)

Specifying downlink signaling of the DCI format; or (b)

Specifying a downlink signaling corresponding to the service; or (b)

Downlink signaling associated with the specified configuration information; or (b)

And the downlink signaling meeting the priority condition, wherein the priority condition comprises the highest priority and/or the lowest priority.

The first downlink signaling may indicate the priority corresponding to the first downlink signaling through a priority identifier configured by the network device.

The second downlink signaling may also be designated MAC CE and/or higher layer signaling.

As an example, if the PDCCH monitoring skip time intervals corresponding to the monitoring adaptive indication information included in the DCIs of the DCI format x_1 and the DCI format x_2 are T1 and T2, the terminal device may determine the PDCCH monitoring skip time intervals T1 and T2 as the target PDCCH monitoring skip time intervals.

As an example, before the PDCCH interception is performed by at least one target search space set, the terminal device receives two pieces of DCI including at least two pieces of interception adaptive indication information for indicating relevant information of a PDCCH interception skip time interval corresponding to at least one search space set, where the two pieces of DCI are DCI in DCI format x_1 and DCI format x_2, and the PDCCH interception skip time interval corresponding to the interception adaptive indication information included in each piece of DCI is T3 and T4, respectively. The terminal device may determine the PDCCH monitoring skip time interval T3 corresponding to the monitoring adaptive indication information included in the DCI of the DCI format x_1 received first as the target PDCCH monitoring skip time interval, or determine the PDCCH monitoring skip time interval T4 corresponding to the monitoring adaptive indication information included in the DCI of the DCI format x_2 received last as the target PDCCH monitoring skip time interval.

As an example, the terminal device receives two DCIs, which are the DCIs of the DCI format x_1 and the DCI format x_2, and PDCCH monitoring skip time intervals corresponding to the monitoring adaptive indication information included in the DCIs of the DCI format x_1 and the DCI format x_2 are T5 and T6, respectively. The terminal device determines, through a service identifier configured by the network, that DCI of DCI format x_1 is used for URLLC service transmission and DCI of DCI format x_2 is used for eMBB service transmission, where the terminal device may determine, as a target PDCCH monitoring skip time interval, a PDCCH monitoring skip time interval T5 corresponding to monitoring adaptive indication information included in DCI for URLLC service transmission, or determine, as a target PDCCH monitoring skip time interval, a PDCCH monitoring skip time interval T6 corresponding to monitoring adaptive indication information included in DCI for eMBB service transmission.

As an example, the terminal device receives two DCIs including at least the monitoring adaptive indication information for indicating the relevant information of the PDCCH monitoring skip time interval corresponding to the at least one search space set, which are the DCIs of the DCI format x_1 and the DCI format x_2, respectively, and the PDCCH monitoring skip time intervals corresponding to the monitoring adaptive indication information included in the DCIs of the DCI format x_1 and the DCI format x_2 are T7 and T8, respectively. The terminal equipment determines the signaling priority of DCI format x_1 and DCI format x_2 through the priority identification configured by the network equipment. The terminal device may determine the PDCCH monitoring skip time interval T7 corresponding to the monitoring adaptive indication information included in the DCI with the highest priority as the target PDCCH monitoring skip time interval, or determine the PDCCH monitoring skip time interval T8 corresponding to the monitoring adaptive indication information included in the DCI with the lowest priority as the target PDCCH monitoring skip time interval.

The downlink signaling associated with the specified configuration information may be downlink signaling associated with a different PDCCH monitoring period or other periodic behavior period or other configuration item, which is not limited herein.

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

As an example, after determining the PDCCH monitoring skip time interval corresponding to the monitoring adaptive indication information included in the at least one first downlink signaling, the terminal device may determine, as the target PDCCH monitoring skip time interval, a PDCCH monitoring skip time interval corresponding to the monitoring adaptive indication information included in the at least one first downlink signaling, and/or a minimum time interval K0min between a reception time of the PDCCH and a reception time of the PDSCH, and/or a minimum time interval K1min between a reception time of the PDSCH and a reception time of the HARQ-ACK, and/or a maximum time interval in a minimum time interval K2min between a reception time of the PDCCH and a transmission time of the PUSCH, or determine, as the target PDCCH monitoring skip time interval, a time interval located within a preset duration interval, or determine, as the target PDCCH monitoring skip time interval, a time interval smaller than a preset threshold, or determine, as the target PDCCH skipping time interval, a time interval greater than the preset threshold, and herein are not limited.

In an alternative embodiment, the at least one target set of search spaces may be a certain set of search spaces, and/or may be a set of sets of search spaces, and/or may be at least one set of search spaces in a set of sets of search spaces, and/or may be a set of sets of search spaces in a plurality of sets of search spaces without configuring a set of sets of search spaces, without limitation herein.

Wherein at least one search space set of the search space set group or the search space set of each search space set in case the search space set group is not configured may be at least one search space set corresponding to a specified service.

Alternatively, a target search space set may be a search space set of some Type, such as Type3CSS and/or USS, at least one search space set within a non-default SSSG, a non-dormant search space set or a non-empty search space set, etc., without limitation.

The set of search space sets, or at least one set of search space sets in which the second downlink signaling in the at least one first downlink signaling is located may be at least one set of search space sets, the set of search space sets, or the set of search space sets in which the second downlink signaling in the at least one first downlink signaling is located, in the specified BWP or the current BWP or the specified set of search space sets or the current set of search space sets, which is not limited herein.

Wherein at least one of the set of search spaces, or the set of search spaces associated with the second downlink signaling of the at least one first downlink signaling may be at least one of the set of search spaces, or the set of search spaces within the specified BWP or the current BWP or the specified set of search spaces or the current set of search spaces, all downlink signaling having the same DCI format as the second downlink signaling, or may be at least one search space set of a set of search space sets, or a set of search space sets in which all downlink signaling belonging to the DCI format of the same type as the second downlink signaling is located within the specified BWP or the current BWP or the specified set of search space sets or the current set of search space sets, which is not limited herein.

In an alternative embodiment, the listening adaptation indication information included in each first downlink signaling may also be used to indicate a handover of the set of search spaces.

In an alternative embodiment, after receiving the at least one first downlink signaling, the terminal device may receive the first configuration information, determine, based on the first configuration information, a number of bits of an information field of the listening adaptive indication information included in at least one of each of the at least one first downlink signaling, and further determine, based on the number of bits of the information field of the listening adaptive indication information included in the at least one first downlink signaling, the listening adaptive indication information included in the at least one first downlink signaling.

The first configuration information is configured by the network device and can be used for directly or indirectly indicating the bit number of an information domain of the monitoring adaptive indication information included in at least one first downlink signaling.

In an alternative embodiment, the first configuration information includes at least one of:

a first number of bits;

the PDCCH corresponding to the at least one first downlink signaling listens for a first number of skipped time intervals and/or a second number of search space set groups configured by the network device.

The first number of bits is the number of bits of the information field of the monitoring adaptive indication information included in the at least one first downlink signaling, for example, may be 0,1,2, or the like, that is, the network device directly indicates the number of bits of the information field of the monitoring adaptive indication information included in the at least one first downlink signaling through the first number of bits in the first configuration information.

Wherein, under the condition that the first configuration information includes a first number of PDCCH monitoring skip time intervals corresponding to at least one first downlink signaling and a second number of search space set groups configured by the network device, the terminal device may determine, based on the first number and/or the second number, a bit number of an information domain of monitoring adaptive indication information included in the at least one first downlink signaling, that is, the network device indirectly indicates, through the first number and the second number in the first configuration information, the bit number of the information domain of monitoring adaptive indication information included in the at least one first downlink signaling.

The specific manner of determining the number of bits of the information field of the listening adaptive indication information included in the at least one first downlink signaling may be shown in the following table, but is not limited to the calculation manner shown in the following table:

the method comprises the steps that a behavior 1 is used for indicating a terminal device not to skip a PDCCH monitoring opportunity when the terminal device monitors PDCCH, a behavior 1A is used for indicating the terminal device to monitor PDCCH according to a corresponding PDCCH monitoring skip time interval when the terminal device monitors PDCCH, a behavior 2 is used for indicating the terminal device to reside in a search space set 0 to monitor PDCCH, a behavior 2A is used for indicating the terminal device to reside in a search space set 1 to monitor PDCCH, and a behavior 2B is used for indicating the terminal device to reside in a search space set 2 to monitor PDCCH, wherein the search space set 0, the search space set 1 and the search space set 2 are used for representing different search space sets.

When the network device does not configure the search space set, that is, the first configuration information only includes the first number of PDCCH monitoring skip time intervals corresponding to at least one first downlink signaling, the number of bits of the information field of the monitoring adaptive indication information included in the at least one first downlink signaling may be expressed as: ceil (log 2 (m+1)). Wherein M is a first number of PDCCH monitoring skip time intervals corresponding to at least one first downlink signaling, and M is greater than or equal to 1. It should be noted that, in the embodiment, the number of bits of the information field of the listening adaptive indication information included in the at least one first downlink signaling may be determined based on the formula ceil (log 2 (m+1)), which is equivalent to, but not limited to, the formula ceil (log 2 (m+1)).

When the terminal device configures the search space set group and the first configuration information only includes the second number, the number of bits of the information field of the listening adaptive indication information included in the at least one second downlink signaling may be expressed as: ceil (log 2 (N)). Where ceil () is a round-up function, N is the second number of search space set groups configured by the network device, and log2 () represents a logarithm of the base 2. Wherein N is greater than or equal to 1. It should be noted that, in the embodiment, the number of bits of the information field of the listening adaptive indication information included in the at least one second downlink signaling may be determined based on the formula ceil (log 2 (N)), which is equivalent to, but not limited to, the formula ceil (log 2 (N)).

When the terminal device configures the search space set group, the number of bits of the information field of the listening adaptive indication information included in the at least one first downlink signaling may be expressed as: ceil (log 2 (m+n)). Wherein ceil () is an upper rounding function, M is a first number of PDCCH monitoring skip time intervals corresponding to at least one first downlink signaling, M is greater than or equal to 0, N is a number of search space set groups configured by a network device, N is greater than or equal to 1, log2 () represents taking a logarithm with 2 as a base. It should be noted that, in the embodiment, the number of bits of the information field of the listening adaptive indication information included in the at least one first downlink signaling may be determined based on the formula ceil (log 2 (m+n)), which is equivalent to, but not limited to, the formula ceil (log 2 (m+n)).

Referring to fig. 2, fig. 2 is another flow chart of a physical downlink control channel PDCCH monitoring method provided in the embodiment of the present application. The physical downlink control channel PDCCH monitoring method provided by the embodiment of the present application may be applicable to a network device, and specifically may include the following steps:

step S21, at least one downlink signaling is sent, where the at least one first downlink signaling includes monitoring adaptive indication information at least used for indicating relevant information of a PDCCH monitoring skip time interval corresponding to the at least one search space set, the at least one first downlink signaling is used for indicating a terminal device to determine at least one target PDCCH monitoring skip time interval based on the monitoring adaptive indication information included in the at least one first downlink signaling, and in case that the at least one target search space set performs PDCCH monitoring, the at least one target PDCCH monitoring skip time interval is used for performing PDCCH monitoring based on the at least one target PDCCH monitoring skip time interval in the at least one target PDCCH monitoring skip time interval.

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

The service corresponding to the at least one first downlink signaling may be, but is not limited to, a URLLC service, an eMBB service, an XR service, or the like.

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

at least one DCI with different bearer information; or (b)

At least one DCI of different DCI formats; or (b)

At least one MAC CE; or (b)

At least one RRC signaling.

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

As an example, the at least one first downlink signaling sent by the network device is DCI with a different DCI format, e.g., may be DCI with a different DCI format size, e.g., DCI format x_1, DCI format x_2 or DCI format 2_x. Where DCI format x_1, DCI format x_2, or DCI format 2_x is abbreviated for a certain type of DCI, where x is an index value, e.g., DCI format x_1 is any one of DCI format 0_1, DCI format 1_1, or DCI format 2_1.

The DCI with different DCI formats may also be DCI with different RNTIs of CRC scrambling. The DCI with different bearer information may be DCI signaling with different purposes, for example, a service identifier configured by a network device indicates that the DCI with different bearer information is used for service transmission of different services.

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 the URLLC service and the eMBB service, respectively.

As an example, the network device sends DCI of DCI format x_1 and DCI format x_2, DCI of DCI format x_1 and DCI format x_2 are used for URLLC traffic transmission and eMBB traffic transmission, respectively, and DCI of DCI format x_1 and DCI format x_2 each include monitoring adaptation indication information for indicating the PDCCH to monitor related information of the skip time interval.

As an example, the network device transmits DCI1 and DCI2, DCI1 is configured on a CSS (e.g., type3 CSS), and DCI2 is configured on a USS. The DCI formats of DCI1 and DCI2 may be the same or different, and are not limited herein. If the network device transmits a plurality of MAC CEs, the plurality of MAC CEs may be the same or different, and the present invention is not limited thereto.

The second duration may be a specified duration agreed for the network device, for example, the second duration may be 2ms, or a certain time slot, or the like, in addition to a PDCCH monitoring period and/or a DRX period and/or a PDCCH monitoring period corresponding to at least one search space set corresponding to when the terminal device monitors the PDCCH in at least one search space set.

The multiple of the second duration may be an integer (e.g., L) or a fraction (1/L), which is not limited herein.

As an example, the network device sends 3 first downlink signaling including monitoring adaptive indication information at least for indicating relevant information of a PDCCH monitoring skip time interval corresponding to at least one search space set, the second duration included in relevant information corresponding to the monitoring adaptive indication information included in each first downlink signaling is multiple {1,1/2,1/4}, and the second duration is a PDCCH monitoring period corresponding to at least one search space set corresponding to when the terminal device monitors the PDCCH in the at least one search space set. The PDCCH monitoring skip time interval corresponding to the monitoring adaptive indication information included in each first downlink signaling is {1,1/2,1/4 }. The PDCCH monitoring period corresponding to the search space set in which the first downlink signaling is located or associated.

If the protocol is defined to carry the same monitoring adaptive indication information between at least one downlink signaling in the same timeslot, the same BWP or the same search space set, the relevant information indicated by the monitoring adaptive indication information included in each first downlink signaling sent by the network device indicates the same PDCCH monitoring time interval.

In an alternative embodiment, the at least one target set of search spaces may be a certain set of search spaces, and/or may be a set of sets of search spaces, and/or may be at least one set of search spaces in a set of sets of search spaces, and/or may be a set of sets of search spaces in a plurality of sets of search spaces without configuring a set of sets of search spaces, without limitation herein. Wherein at least one search space set of the search space set group or the search space set of each search space set in case the search space set group is not configured may be at least one search space set corresponding to a specified service.

Optionally, the network device may indicate, through relevant information indicated by the listening adaptation indication information included in the at least one first downlink signaling, that a certain set of search spaces within the BWP, or a set of search spaces, or at least one set of search spaces in the set of search spaces, or PDCCH listening skip time intervals corresponding to the set of search spaces in each set of search spaces in the case where the set of search spaces is not configured.

Wherein the specified BWP may be at least one of a non-default BWP, a dormant BWP, a non-dormant BWP, or a current BWP.

The specified BWP corresponding to the different first downlink signaling may be the same or different, and when the specified BWP corresponding to the different downlink signaling is the same, a certain search space set indicated by the related information corresponding to the different first downlink signaling, or a search space set group, or at least one search space set in the search space set group, or a search space set in each search space set in the case of not configuring the search space set group may be the same or different, which is not limited herein.

Wherein the specified set of search space sets may be at least one of a non-default set of search space sets, a default set of search space sets, or any set of search space sets.

As an example, if the DCI format of a certain first downlink signaling sent by the network device is DCI format x_1, the downlink signaling includes monitoring adaptive indication information for indicating a PDCCH monitoring skip time interval corresponding to at least one of a search space set group, a search space set, or a search space set in which all DCI identical to DCI format x_1 is located in a current BWP and/or a current search space set group.

Optionally, the network device may instruct, through different first downlink signaling, a search space set, a PDCCH listening skip time interval corresponding to at least one search space set in the search space set or the search space set group corresponding to different services.

For time sensitive services, the configuration of the small-granularity PDCCH monitoring skip time interval can be more flexible when the terminal equipment monitors the PDCCH in the corresponding search space set. For the less time-sensitive or bursty service, the signaling overhead can be saved by configuring a PDCCH monitoring skip time interval with larger granularity, such as a corresponding PDCCH monitoring period or N times of a certain designated duration when configuring a corresponding search space set to perform PDCCH monitoring.

Optionally, the network device may instruct, through different first downlink signaling, a PDCCH listening skip time interval corresponding to at least one of a search space set group, a search space set, or a search space set group associated with different control resource sets, or instruct, through different first downlink signaling, a different PDCCH listening skip time interval corresponding to at least one of a search space set group, a search space set, or a search space set group associated with the same control resource set.

Example two:

The network device respectively transmits two DCIs including monitoring adaptive indication information for indicating at least related information of a PDCCH monitoring skip time interval corresponding to at least one search space set at different time, which are DCIs of DCI format x_1 and DCI format x_2 respectively. The terminal equipment firstly receives DCI of DCI format x_1 and determines that the PDCCH monitoring skip time interval corresponding to the monitoring adaptive indication information included in the DCI is T3. Before the application time point (such as the next time slot) of the monitoring self-adaptive behavior, the terminal equipment receives the DCI in the DCI format x_2 again, and determines that the PDCCH monitoring skip time interval corresponding to the monitoring self-adaptive indication information included in the DCI is T4.

Or, the terminal device may determine the PDCCH monitoring skip time interval T4 corresponding to the monitoring adaptive indication information included in the last received DCI as the target PDCCH monitoring skip time interval, and perform PDCCH monitoring based on at least one search space set in the search space set, the search space set, the search space set or the search space set where the last received DCI is located or associated with T4, that is, skip the corresponding PDCCH monitoring opportunity on at least one search space set in the search space set, the search space set or the search space set where the DCI is located or associated with the last received DCI based on the PDCCH monitoring skip time interval T4.
