Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a method for monitoring a Physical Downlink Control Channel (PDCCH) provided by an embodiment of the present application. The physical downlink control channel PDCCH monitoring method provided in the embodiment of the present application is applicable to terminal equipment, and may specifically include the following steps:

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

In some feasible implementation manners, the terminal device may 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 one The monitoring adaptive indication information of the relevant information of the PDCCH monitoring skip time interval.

Optionally, the listening adaptation indication information included in each first downlink signaling may also be used to indicate switching of search space sets.

As an example, each first downlink signaling received by the terminal device includes monitoring adaptation indication information, and each monitoring adaptation indication information is at least used to indicate the PDCCH monitoring skip time interval corresponding to at least one search space set Related Information.

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

Wherein, each monitoring adaptation indication information is used to indicate the relevant information of the PDCCH monitoring skip time interval corresponding to at least one search space set, that is, to indicate the corresponding PDCCH monitoring skip time interval when the terminal device performs PDCCH monitoring in at least one search space set. information about the time interval.

Wherein, the relevant information of the PDCCH monitoring skip time interval indicated by each monitoring adaptation indication information may be the same or different, and no limitation is set here.

Step S12: Determine at least one target PDCCH monitoring skip time interval based on the monitoring adaptation indication information included in the at least one first downlink signaling.

In some feasible implementation manners, when at least one target PDCCH monitoring skip time interval is determined based on the monitoring adaptive indication information included in at least one first downlink signaling, the monitoring time interval included in each first downlink signaling may be determined. For the PDCCH monitoring skip time interval corresponding to the adaptive indication information, at least one target PDCCH monitoring skipping time interval is determined from the PDCCH monitoring skipping time intervals corresponding to each first downlink signaling.

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

It should be noted that, the foregoing manner of determining at least one target PDCCH listening skip time interval is only an example, and may be specifically determined based on actual application scenario requirements, and is not limited here.

Step S13 , in the case of performing PDCCH monitoring in at least one target search space set, performing PDCCH monitoring based on at least one target PDCCH monitoring skipping time interval in the at least one target PDCCH monitoring skipping time interval.

In some feasible implementation manners, after at least one target PDCCH monitoring skip time interval is determined, PDCCH monitoring may be performed in the target search space set based on each target PDCCH monitoring skip time interval.

In some feasible implementation manners, when a 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.

Optionally, when multiple 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, the arrangement order of target PDCCH monitoring skip time intervals may be determined, and then PDCCH monitoring is performed in a target search space set according to different target PDCCH monitoring skip time intervals in the arrangement order.

Alternatively, when multiple target PDCCH monitoring skip time intervals are determined, different target PDCCH monitoring skip time intervals may be corresponding PDCCH monitoring skip time intervals when PDCCH monitoring is performed in different target search space sets. Therefore, when PDCCH monitoring is performed for each target search space set, PDCCH monitoring is performed according to the corresponding target PDCCH monitoring skip time interval.

Wherein, each target search space set may be a certain search space set, and/or may be a search space set group (Search Space Set Group, SSSG), and/or at least one search space set in the search space set group, and /or a set of search space sets in multiple search space sets when no search space set is configured, which is not limited here.

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 through the service identifier corresponding to each first downlink signaling configured by the network device, Indicates that the corresponding first downlink signaling is used for service transmission of different services.

Wherein, at least one service corresponding to the first downlink signaling may be Ultra-Reliable and Low Latency Communications (Ultra-Reliable and Low Latency Communications, URLLC) service or Enhanced Mobile Broadband (Enhanced Mobile Broadband, eMBB) service or extended reality (extend reality, XR) business, etc., but not limited to this.

Wherein, 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 corresponding to each DCI configured by the network device indicates that the corresponding DCI is used for different business services transmission.

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

at least one downlink control information DCI; or

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

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

That is, 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 When , one or more of the bearer information of each DCI, the DCI format, or the parameter configuration of the associated search space set may be the same or different, and there is no limitation here.

For example, when the downlink control information DCI is greater than or equal to two, the bearer information of each DCI is not completely the same, and/or the format of each DCI is not completely the same, and/or the parameter configuration of the search space set associated with each DCI is not completely the same.

As an example, the at least one first downlink signaling received by the terminal device is DCI with different DCI formats, such as DCI with different DCI formats and sizes, such as 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 an abbreviation for a certain type of DCI, where x refers to a value, such as DCI format x_1 is any DCI in DCI format 0_1 or DCI format 1_1 or DCI format 2_1 .

Wherein, DCIs with different DCI formats may also be DCIs with different Radio Network Temporary 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 that may be 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.

Among them, the search space sets associated with different parameter configurations may be search space sets associated with different types, search space sets associated with different PDCCH monitoring periods, search space sets associated with different control resource sets (CORESET), search spaces associated with different monitoring patterns Sets, search space sets associated with different monitoring positions, or search space sets associated with different numbers of continuous monitoring time slots, one or more combinations, which are not limited here.

As an example, the terminal device receives DCI1 and DCI2, DCI1 is configured in a common search space (Common Search Space, CSS) (such as type3 CSS), and DCI2 is configured in a user-specific search space (UE-Specific Search Space, USS). In addition, DCI formats of DCI1 and DCI2 may be the same or different, which is not limited here.

Wherein, if the terminal device receives multiple MAC CEs, the multiple MAC CEs received may be the same or different, and there is no limitation here.

Similarly, if the terminal device receives multiple RRC signalings, the multiple received RRC signalings may be the same or different, which is not limited here.

In an optional embodiment, the relevant information of the PDCCH monitoring skip time interval indicated by each monitoring adaptation indication information includes at least one of the following:

The first duration, the first duration is used to indicate the PDCCH monitoring skip time interval corresponding to at least one search space set; or

A multiple of the second duration, the second duration includes the PDCCH monitoring period corresponding to at least one search space set corresponding to the terminal device when performing PDCCH monitoring in at least one search space set and/or the period of Discontinuous Reception (DRX) and/or or specify a duration.

Wherein, the first duration may be a fixed duration, for example, the first duration may be a fixed duration in units of milliseconds or seconds, or may be a corresponding duration of symbols, subframes, or wireless frames, or may be a network device configuration or protocol agreement Other durations are not limited here.

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

Wherein, the second duration may be the PDCCH monitoring period DRX period and/or the PDCCH monitoring period corresponding to at least one search space set corresponding to at least one search space set when the terminal device performs PDCCH monitoring, and may also be network equipment configuration or protocol An agreed specified duration, for example, the second duration may be 2 ms, or a certain time slot.

Wherein, the multiple of the second duration can be an integer or a fraction, which is not limited here.

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

Wherein, the PDCCH monitoring skip time intervals corresponding to the monitoring adaptation indication information included in each first downlink signaling may be the same or different. For example, the monitoring adaptive indication information included in different first downlink signaling may correspond to the same first duration or a multiple of the second duration, or may correspond to different first durations or multiples of the second duration, and there is no limitation here .

As an example, the terminal device receives 3 first downlink signalings, and each first downlink signaling includes at least the monitoring self used to indicate the relevant information of the PDCCH monitoring skip time interval corresponding to at least one search space set. Adaptation indication information, the multiples of the second duration included in the relevant information corresponding to the monitoring adaptation indication information included in each first downlink signaling are {1, 2, 4}, and the second duration is the terminal device in at least one A PDCCH monitoring period corresponding to at least one search space set when the search space set performs PDCCH monitoring. Then, 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 optional embodiment, at least one target PDCCH monitoring skip time interval is determined based on the monitoring adaptation indication information included in at least one first downlink signaling, including at least one of the following:

Determining the PDCCH monitoring skip time interval corresponding to the monitoring adaptation indication information included in at least one first downlink signaling as the target PDCCH monitoring skipping time interval; or

The first time interval meeting the time interval condition is determined as the target PDCCH monitoring skip time interval, the time interval condition includes at least one of the maximum time interval or the minimum time interval, and the first time interval includes at least one of the following:

Wherein, each first downlink signaling may indicate its corresponding priority through a priority identifier configured by the network device.

Wherein, the second downlink signaling can also be a designated MAC CE and/or higher layer signaling.

As an example, the PDCCH monitoring skip time intervals corresponding to the PDCCH monitoring skipping time intervals corresponding to the monitoring adaptive indication information included in the DCI format x_1 and DCI format x_2 received by the terminal device are T1 and T2, then the PDCCH monitoring skipping time intervals T1 and T2 can be determined The time interval is skipped for target PDCCH listening.

As an example, before at least one target search space set performs PDCCH monitoring, the terminal device successively receives two pieces of monitoring adaptation indication information including at least relevant information indicating the PDCCH monitoring skip time interval corresponding to at least one search space set. DCIs, which are respectively DCIs of the DCI format x_1 and DCI format x_2, and the PDCCH monitoring skip time intervals corresponding to the monitoring adaptation indication information included in each DCI are T3 and T4 respectively. The terminal device may determine the PDCCH monitoring skip time interval T3 corresponding to the monitoring adaptation indication information contained in the DCI format x_1 received first as the target PDCCH monitoring skipping time interval, or use the last received DCI format x_2 The PDCCH monitoring skip time interval T4 corresponding to the monitoring adaptation indication information included in the DCI is determined as the target PDCCH monitoring skipping time interval.

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

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

Wherein, the downlink signaling associated with the specified configuration information may be downlink signaling associated with different PDCCH monitoring periods or other periodic behavior periods or other configuration items, which is not limited here.
