Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a method and apparatus for determining PDCCH listening adaptive behavior. Background Technology

[0002] In New Radio (NR, also known as 5G) systems, terminal devices monitor the Physical Downlink Control Channel (PDCCH) to determine if downlink scheduling information is available. The PDCCH monitoring process involves the terminal device decoding the PDCCH and then using a Cyclic Redundancy Check (CRC) to verify whether it contains downlink control information (DCI) carrying the terminal device's scheduling information.

[0003] The base station allocates one or more search spaces to users via higher-layer signaling. The configuration of each search space is periodic, and users perform PDCCH detection within their assigned search space. Each instance of PDCCH detection is called a PDCCH monitoring occasion. Search spaces are typically configured periodically. In a 5G NR system, to obtain downlink scheduling information, the UE needs to monitor the PDCCH during each PDCCH monitoring occasion to determine if downlink scheduling information is available. Each PDCCH monitoring process is a PDCCH decoding process, and the result is then used to determine if it contains DCI (Distributed Control Information) carrying the UE's scheduling information. If the PDCCH contains the user's scheduling information, the UE receives a positive CRC checksum and can obtain the scheduling information carried in the DCI; otherwise, the CRC checksum is negative, and the UE cannot obtain any scheduling information from the DCI.

[0090] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0091] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0092] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0093] To help understand the solutions of the embodiments of this application, the following will briefly introduce the relevant concepts that may be involved in this application:

[0094] 1) PDCCH listening adaptive behavior, including at least one or a combination of the following behaviors:

[0095] Behavior 1: Skip PDCCH listening without activating it, i.e., perform PDCCH listening according to the pre-configured search space.

[0096] Action 1A: PDCCH listening skip, that is, stop listening to PDCCH during the time period X, where X is a value greater than or equal to 0.

[0097] Behavior 2: Listen to the search space set associated with SSSG#0.

[0098] Behavior 2A: Listen to the search space set associated with SSSG#1.

[0099] Behavior 2B: Listen to the search space set associated with SSSG#2.

[0100] 2) PDCCH monitoring:

[0101] The base station allocates one or more search spaces to users via higher-layer signaling. The configuration of each search space is periodic, and users perform PDCCH detection within their assigned search space. Each instance of PDCCH detection is called a PDCCH monitoring occasion. Search spaces are typically configured periodically. In a 5G NR system, to obtain downlink scheduling information, the UE needs to monitor the PDCCH during each PDCCH monitoring occasion to determine if downlink scheduling information is available. Each PDCCH monitoring process is a PDCCH decoding process, and the result is then used to determine if it contains DCI (Distributed Control Information) carrying the UE's scheduling information. If the PDCCH contains the user's scheduling information, the UE receives a positive CRC checksum and can obtain the scheduling information carried in the DCI; otherwise, the CRC checksum is negative, and the UE cannot obtain any scheduling information from the DCI.

[0102] The parameters for the search space of PDCCH are configured as follows:

[0103] 1. The index of the search space set, i.e., the search space ID.

[0104] 2. The control resource set number used to establish the relationship between the search space s and the control resource set p, i.e., CORESETID.

[0105] 3. Monitoring Slot Periodicity and Offset: Indicates the PDCCH monitoring period k. s and offset value o s The unit for each parameter is a time slot, and the terminal uses this configuration parameter to determine the slot for listening to the downlink control channel.

[0106] 4. Monitoring SymbolsWithinSlot indicates the monitoring pattern of the PDCCH within a slot, and indicates the position of the first symbol of the CORESET within a slot.

[0107] 5. Listening duration, indicating the number of time slots T occupied by the search space set s. s And T s <k s .

[0108] 6. The number of PDCCH candidates contained in each aggregation level L within the search space. Supported aggregation levels include {1, 2, 4, 8, 16}, which can be configured via independent parameters.

[0109] 7. The flag searchspaceType is used to distinguish whether the current search space is a public search space or a terminal-specific search space.

[0110] 8. For the Common Search Space (CSS), specify the DCI format.

[0111] 9. For the UE-specific search space set (USS), it is indicated by a specific DCI format.

[0112] 10. Frequency domain monitoring locations (freqMonitorLocations): The bitmap indicates the index of one or more resource blocks (RBs) within the search space. Each "1" in the bitmap indicates an RB set k, starting at position k. in, This represents the index of the starting RB of set k. This is the RB offset value. The frequency domain resource allocation pattern is determined based on the CORESET configuration associated with this search space.

[0113] 3) Search space switching process

[0114] When the UE capability indicates whether the UE supports at least one of two search space set handover methods: searchSpaceSetGroupSwitchingwithoutDCI-r16 and / or searchSpaceSetGroupSwitchingwithDCI-r16, the UE will perform a search space set handover if the gNB configures a search space set group list searchSpaceGroupIdList-r16 for the UE based on the UE capability, indicating which serving cells(s) will perform the search space set handover process; otherwise, the UE will not perform the search space set handover process. If the UE is configured with searchSpaceGroupIdList-r16 and simultaneously configured with searchSpaceGroupIDList-r16 indicating the corresponding search space set group, the UE will reconfigure the search set according to search space set group 0 (SSSG0) and perform the corresponding PDCCH listening.

[0115] Search space set grouping applies only to Type-3 Public Search Space (CSS) and User-Specific Search Space (USS) search space sets. When a search space set does not have a search space set group index configured, the terminal needs to continuously monitor that search space set.

[0116] There are two types of search space set switching indications: explicit and implicit, distinguished by whether SearchSpaceSwitchTrigger-r16 is configured in the RRC signaling. If configured, it is an explicit indication; otherwise, it is an implicit indication.

[0117] For explicit indications, the handover between search space group 0 and search space group 1 is triggered via the search space group handover trigger indication in DCI format 2_0. Additionally, the base station configures a search space group handover timer, searchSpaceSwitchingTimer-r16, via RRC signaling. When this timer expires, or after the last symbol of the remaining channel occupancy duration carried in the search space of the configured DCI format 2_0 for the UE, the UE will fall back to the default search space group for listening. Search space group 0 (SSSG0) is the default search space group. The timer searchSpaceSwitchingTimer-r16 is activated when the UE hands over to search space group 1. There is a certain delay when the UE hands over between search space group 0 (SSSG0) and search space group 1 (SSSG1). Depending on the UE's capabilities, this delay is categorized as Capability 1 or Capability 2, and is configured by the gNB via higher-layer signaling based on the UE's capabilities.

[0118] Table 1 Switching delay P switch The minimum value [symbol]

[0119] μ UE processing capability 1 [symbol] UE processing capability 2 [symbol] 0 25 10 1 25 12 2 25 22

[0120] Implicit indications trigger search space set handover based on whether the UE detects the DCI format of the corresponding search space set. If the UE detects a DCI configured in search space set 0, the UE begins configuring search space set 1 for PDCCH listening and stops PDCCH listening in search space set 0. When any DCI in search space set 1 is detected, the timer searchSpaceSwitchingTimer-r16 is started. When the timer countdown expires, or after the last symbol of the remaining channel occupancy duration carried in the search space of the configured DCI format 2_0, the UE switches from search space set 1 back to search space set 0. Similar to explicit indications, there is a certain delay when switching between search space set 0 and search space set 1. Depending on the UE's capabilities, it is divided into Capability 1 and Capability 2, configured by the gNB through higher-layer signaling based on the UE's capabilities.

[0121] 4) Standardization discussions on PDCCH monitoring adaptive enhancement in connected state:

[0122] A third search space group, SSSG#2, is introduced during search space group switching to further enhance power saving for connected terminals. For example, SSSG#2 can be set to a sleep group or not associated with a search space group, thereby reducing terminal PDCCH listening behavior through SSSG switching to SSSG2.

[0123] Furthermore, the SSSG switching specified in the Rel-16 protocol is notified via group messages and does not apply to terminal-specific indications. The RAN (Wireless Access Network) 1#105e meeting concluded that the PDCCH listening adaptive indication is carried in the scheduling DCI; this DCI is a UE-specific indication.

[0124] Both PDCCH listener skipping and SSSG handover have their advantages: PDCCH listener skipping can dynamically and flexibly instruct users to listen to PDCCH, while SSSG handover can instruct the terminal to listen to PDCCH within different search space sets. They can work together, meaning the terminal can be instructed to perform different adaptive PDCCH listener behaviors depending on the situation. However, for PDCCH listener skipping, if dynamically indicating different skipping intervals is required, then the adaptive PDCCH listener instruction may be insufficient to indicate these two different types of adaptive PDCCH behaviors.

[0125] This application enables the terminal to quickly receive the PDCCH when the base station preempts the unlicensed frequency band by searching the space set for switching. Typically, users listen for the PDCCH frequently before the channel occupancy period, allowing for rapid PDCCH acquisition. This means that once the base station preempts the unlicensed frequency band, the UE can begin data transmission as quickly as possible. However, when the terminal is in the channel occupancy period, the PDCCH listening period is longer, which can reduce blind detection to some extent, thus achieving energy saving for the terminal.

[0126] Figure 1 This is one of the flowcharts illustrating the method for determining PDCCH listening adaptive behavior provided in the embodiments of this application, such as... Figure 1 As shown in the embodiments of this application, a method for determining the adaptive behavior of PDCCH listening is provided, and the executing entity can be a terminal device, such as a mobile phone.

[0127] The method includes:

[0128] Step 101: Receive PDCCH monitoring adaptation indication information sent by the network-side device, wherein the PDCCH monitoring adaptation indication information includes first indication information;

[0129] Step 102: Determine the PDCCH listening adaptive behavior based on the indication information of PDCCH listening adaptation;

[0130] The first indication information is any one of the following: not enabling PDCCH listening skip, PDCCH listening skip target time interval, and switching to or residing in the target search space group SSSG.

[0131] Specifically, the terminal device receives PDCCH monitoring adaptive indication information sent by the network-side device, which includes first indication information. The first indication information can be any one of {not enabling PDCCH monitoring skip, PDCCH monitoring skip target time interval, switching to or residing in the target search space set SSSG}.

[0132] Among them, PDCCH listening skipping is not enabled, that is, normal or regular PDCCH listening and / or PDCCH listening skipping target time interval is zero according to the pre-configured search space;

[0133] PDCCH listens for the skip target time interval, including two cases:

[0134] If no specific time interval is given, it means that the PDCCH listener skips the target time interval. The specific time interval is uncertain and may be one or more combinations.

[0135] If a specific time interval is given, it represents any one or more combinations of a set {PDCCH listener skip target time interval 1, ..., PDCCH listener skip target time interval N}, where N represents the number of target time intervals, with a value greater than or equal to 1 and a value greater than or equal to 0 for each target time interval.

[0136] Similarly, switching to or residing in the target search space group SSSG may include the following indication information:

[0137] 1. Switching to or residing in the target search space set does not indicate a specific SSSG, but represents the type of behavior of switching to or residing in the target search space set SSSG, where the target SSSG is an indeterminate SSSG.

[0138] 2. Switching to or residing in the target search space set indicates a specific SSSG, which represents any one or more combinations of a set {switching to or residing in target SSSG0, ..., switching to or residing in target SSSGM}, where M represents the index value of the target SSSG, which is greater than or equal to 0.

[0139] Upon receiving the aforementioned first instruction information, the terminal device determines its PDCCH monitoring adaptive behavior, such as monitoring PDCCH according to the search space configuration, not monitoring PDCCH for a certain period of time, monitoring PDCCH in a specific search space group, or switching the search space group SSSG.

[0140] The method for determining PDCCH listening adaptive behavior provided in this application determines PDCCH listening adaptive behavior by configuring different PDCCH listening adaptive indication information. This can flexibly instruct different PDCCH listening behaviors of the terminal device or switch the PDCCH listening behavior, thereby saving the listening power consumption of the terminal device and ensuring timely data transmission.

[0141] Optionally, the PDCCH listening adaptive behavior includes at least: not enabling PDCCH listening skip, skipping the target time interval for a specific period of time, and switching to or residing in a specific SSSG in the target SSSG set.

[0142] Specifically, based on different PDCCH listening adaptive indication information, the determined PDCCH listening adaptive behavior includes at least the following:

[0143] If PDCCH listening is not enabled, skip the process; that is, the terminal device performs normal or regular PDCCH listening.

[0144] PDCCH listening skips a specific time period of the target time interval, meaning that the terminal device does not perform PDCCH listening during a specific time period.

[0145] Switching to or residing in the target SSSG, where the target SSSG is a specific SSSG, indicates two scenarios:

[0146] Scenario 1: The terminal switches to a specific SSSG and performs PDCCH listening according to the listening opportunities configured in the specific SSSG. The specific SSSG is different from the SSSG originally configured for the terminal device.

[0147] Scenario 2: The terminal device resides in a specific SSSG and performs PDCCH listening according to the listening opportunities configured in the specific SSSG. The specific SSSG is the same as the SSSG originally configured for the terminal device.

[0148] The method for determining PDCCH listening adaptive behavior provided in this application determines PDCCH listening adaptive behavior by configuring different PDCCH listening adaptive indication information. This can flexibly instruct different PDCCH listening behaviors of the terminal device or switch the PDCCH listening behavior, thereby saving the listening power consumption of the terminal device and ensuring timely data transmission.

[0149] Optionally, the PDCCH listening skip target time interval is applied to any of the following scenarios:

[0150] The first search space set where the first indication information is located, the specific search space set, the pre-configured specific SSSG, and the currently active BWP (Band Width Part).

[0151] Specifically, PDCCH listener skip adaptive can be applied to any one or more of the following specific scenarios:

[0152] Taking the first indication information of 2 bits, and the base station and terminal supporting a maximum of 3 SSSGs as an example, {00, 01, 10, 11} correspond to {not enabling PDCCH listening and skipping, PDCCH listening and skipping target time interval 1, PDCCH listening and skipping target time interval 2, switching to or staying in the target SSSG} respectively.

[0153] The first indication information PDCCH listening skipping behavior applies only to the search space set or specific search space set where the first indication information is located, i.e., the first search space set or specific search space set corresponding to the signaling carrying the first indication information. Here, the specific search space set can be specified by higher-layer signaling or protocol. When the network-side device, such as the base station, sends the first indication information as "01" or "10", the terminal is instructed not to perform PDCCH listening on the corresponding search space set, and the skipping time is target time interval 1 or target time interval 2, respectively. If the base station sends the first indication information as "11", the terminal is instructed to listen only to the PDCCH on the target SSSG, and listen according to the search space configuration on that SSSG. The target SSSG can be SSSG0, SSSG1, or SSSG2, specifically pre-configured by higher-layer signaling or specified by protocol.

[0154] The PDCCH snooping skipping behavior in the first indication information can be applied to a specific configured SSSG, such as the current SSSG or an SSSG associated with snooping according to the protocol, i.e., all or part of the search space set in that SSSG, which needs to be skipped according to the corresponding skipping time interval in the first indication information. Different PDCCH snooping skipping target time intervals N in the first indication information can be applied to the same SSSG or to different SSSGs. For example, PDCCH snooping skipping target time interval 1 or PDCCH snooping skipping target time interval 2 is only used for at least one of SSSG0, SSSG1, and SSSG2. The target SSSG can be SSSG0, SSSG1, or SSSG2, specifically configured by higher-layer signaling or specified by the protocol. When the network-side device, such as the base station, sends the first indication information as "01" or "10", it instructs the terminal not to enable PDCCH snooping skipping on the specific SSSG, with the skipping time being target time interval 1 or target time interval 2, respectively. If the base station sends the first indication information as "11", it instructs the terminal to snoop only on the PDCCH on the target SSSG, according to the search space configuration on that SSSG. The target SSSG can be SSSG0, SSSG1, or SSSG2, depending on the pre-configuration of higher-level signaling or the protocol.

[0155] The PDCCH listening skipping behavior in the first indication information can be applied to the currently active BWP. That is, all designated PDCCHs configured on the currently active BWP, taking PDCCHs in the Type 3 public search space or UE-specific search space as examples, must skip PDCCH listening for the target time interval. When the base station sends the first indication information as "01" or "10", it instructs the terminal not to perform designated PDCCH listening on the currently active BWP, with skip times of target time interval 1 or target time interval 2, respectively. If the base station sends the first indication information as "11", it instructs the terminal to only listen to the PDCCH on the target SSSG, according to the search space configuration on that SSSG. The target SSSG can be SSSG0, SSSG1, or SSSG2, specifically configured through higher-layer signaling or protocol specifications.

[0156] The method for determining PDCCH listening adaptive behavior provided in this application determines PDCCH listening adaptive behavior by configuring different PDCCH listening adaptive indication information. This can flexibly instruct different PDCCH listening behaviors of the terminal device or switch the PDCCH listening behavior, thereby saving the listening power consumption of the terminal device and ensuring timely data transmission.

[0157] Optionally, determining the PDCCH listening adaptive behavior based on the indication information includes:

[0158] If the indication information for PDCCH listening adaptation also includes second information, the PDCCH listening adaptation behavior is determined based on the first indication information and the corresponding second information.

[0159] Wherein, the first indication information is when switching to or residing in the target SSSG, and the second information is used to indicate that the target SSSG is a specific SSSG;

[0160] Alternatively, when the first indication information is a PDCCH listening skip target time interval, the second information is used to indicate that the target time interval is a specific time period;

[0161] Alternatively, if the first indication information does not include the configuration of the default or initial SSSG, the second information is used to indicate the default or initial SSSG;

[0162] Alternatively, if the first indication information cannot indicate that PDCCH listening should not be enabled and skipped, the second information is used to indicate that PDCCH listening should not be enabled and skipped.

[0163] Specifically, the PDCCH listening adaptation indication information received from the network-side device may include a second information in addition to the first indication information mentioned above. The second information is used to provide auxiliary indication of the terminal's specific PDCCH listening adaptation behavior. For example, if the target time interval or target SSSG is uncertain in the first indication information, or if it does not include the relevant configuration for returning to the normal PDCCH listening state (i.e., skipping PDCCH listening without enabling it, and / or performing PDCCH listening on the default or initial SSSG), the second information can indicate which specific time interval, or which specific SSSG, or indicate the configuration for returning to the normal or regular PDCCH listening state (configuring the default or initial SSSG, and / or skipping PDCCH listening without enabling it).

[0164] The specific configurations of the first and second information mentioned above are as follows:

[0165] When the first indication information is for switching to or residing in the target SSSG, the second information is used to indicate that the target SSSG is a specific SSSG; or,

[0166] When the first indication information is that the PDCCH listening skips the target time interval, the second information is used to indicate that the target time interval is a specific time period;

[0167] Alternatively, if the first indication information does not include the configuration of the default or initial SSSG, the second information is used to indicate the default or initial SSSG;

[0168] Alternatively, if the first indication information cannot indicate that PDCCH listening should not be enabled and skipped, the second information is used to indicate that PDCCH listening should not be enabled and skipped.

[0169] The method for determining PDCCH monitoring adaptive behavior provided in this application combines the first and second information in the PDCCH monitoring adaptive indication information to configure different indication information and determine the PDCCH monitoring adaptive behavior. This method can flexibly indicate different PDCCH monitoring behaviors of the terminal device or switch the PDCCH monitoring behavior, thereby saving the monitoring power consumption of the terminal device and ensuring timely data transmission.

[0170] Optionally, determining the PDCCH listening adaptive behavior based on the indication information includes:

[0171] If the indication information for PDCCH listening adaptation also includes second information, and PDCCH listening skip related information and / or SSSG switching related information have been pre-configured, the PDCCH listening adaptive behavior is determined based on the pre-configured PDCCH listening skip related information and / or SSSG switching related information, the second information, and the first indication information.

[0172] Wherein, if the second information indicates pre-configured PDCCH listening skip related information, then the first indication information and the pre-configured PDCCH listening skip related information correspond one-to-one;

[0173] If the second information indicates pre-configured SSSG handover related information, then the first indication information and the pre-configured SSSG handover related information correspond one-to-one;

[0174] The pre-configured PDCCH listening skip information includes: not enabling PDCCH listening skip, and / or a set of target time intervals for PDCCH listening skip;

[0175] The pre-configured SSSG switching information includes: not performing SSSG listening, and / or switching to or residing in the target SSSG set.

[0176] Specifically, when a terminal device receives an indication message for PDCCH snooping adaptation sent by a network-side device, and the indication message includes a first indication message and a second message, if higher-layer signaling or protocol specifies that PDCCH snooping skip related information and SSSG handover related information have been pre-configured, then the terminal device determines its PDCCH snooping adaptation behavior based on the first indication message, the second message, and the aforementioned pre-configured information.

[0177] The specific determination method is as follows:

[0178] If the pre-configuration information indicated by the second information contains PDCCH listening skip related information, the PDCCH listening skip related information includes: not enabling PDCCH listening skip, and a set of PDCCH listening skip target time intervals, for example: {not enabling PDCCH listening skip, PDCCH listening skip target time interval 1, ..., PDCCH listening skip target time interval N-1}, where N is the number of indication information included in the first indication information.

[0179] If the pre-configuration information indicated by the second information contains SSSG switching related information, the SSSG switching related information includes: not performing SSSG monitoring, and / or switching to or residing in a set of target SSSGs, for example: {not performing SSSG monitoring, switching to or residing in target SSSG0, ..., switching to or residing in target SSSGM-2}, or {switching to or residing in target SSSG0, ..., switching to or residing in target SSSGM}, where M is the number of indication information included in the first indication information. Not performing SSSG monitoring means not monitoring according to the search space set grouping method, that is, all search spaces configured by RRC must be monitored.

[0180] Taking the 2-bit first indication information as an example, the pre-configured PDCCH listening skip information is {PDCCH listening skip not enabled, PDCCH listening skip target time interval 1, PDCCH listening skip target time interval 2, PDCCH listening skip target time interval 3}. The pre-configured SSSG switching information is {SSSG listening not enabled, switching to or residing in target SSSG0, switching to or residing in target SSSG1, switching to or residing in target SSSG2}.

[0181] If the second information indicates the pre-configured PDCCH listening skip related information, then the {00, 01, 10, 11} of the first indication information correspond to {PDCCH listening skip not enabled, PDCCH listening skip target time interval 1, PDCCH listening skip target time interval 2, PDCCH listening skip target time interval 3} respectively.

[0182] If the second information indicates pre-configured SSSG switching related information, then the {00, 01, 10, 11} of the first indication information correspond to {not performing SSSG listening, switching to or residing in target SSSG0, switching to or residing in target SSSG1, switching to or residing in target SSSG2} respectively.

[0183] The method for determining PDCCH monitoring adaptive behavior provided in this application combines the first and second information in the PDCCH monitoring adaptive indication information to configure different indication information and determine the PDCCH monitoring adaptive behavior. This method can flexibly indicate different PDCCH monitoring behaviors of the terminal device or switch the PDCCH monitoring behavior, thereby saving the monitoring power consumption of the terminal device and ensuring timely data transmission.

[0184] Optionally, when the second information is used to indicate that the target SSSG is a specific SSSG, or when the second information is used to indicate that the target time interval is a specific time period, the bearer of the second information is one or a combination of DCI signaling, MAC (Media Access Control) layer signaling, or RRC (Radio Resource Control) signaling.

[0185] Specifically, the second information can be sent through various signaling methods, including DCI signaling, MAC layer signaling, or RRC signaling, and can be any one or a combination of these.

[0186] The method for determining PDCCH monitoring adaptive behavior provided in this application combines the first and second information in the PDCCH monitoring adaptive indication information to configure different indication information and determine the PDCCH monitoring adaptive behavior. This method can flexibly indicate different PDCCH monitoring behaviors of the terminal device or switch the PDCCH monitoring behavior, thereby saving the monitoring power consumption of the terminal device and ensuring timely data transmission.

[0187] Optionally, the downlink signaling carrying the second information includes one or more of the following combinations:

[0188] Based on newly added or specific bit information in DCI signaling, MAC signaling, or RRC signaling, indicate specific SSSG-related information, or indicate PDCCH listening to skip related information;

[0189] Based on the redefinition of existing information fields in the DCI signaling, indicate specific SSSG-related information, or instruct the PDCCH to listen for and skip related information;

[0190] The specific SSSG-related information includes any of the following: not listening to SSSGs, switching to or residing in any SSSG in the target SSSG set, and the target SSSGs are different SSSGs;

[0191] The information related to PDCCH listening skipping includes any of the following: PDCCH listening skipping is not enabled, or any time period in the set of target time intervals for PDCCH listening skipping, and the target time intervals are different time periods.

[0192] Specifically, when the first indication information is to switch to or reside in the target SSSG, and the second information is used to indicate that the target SSSG is a specific SSSG, the second information is carried by the second downlink signaling, such as DCI / MAC CE / RRC signaling.

[0193] Taking a 2-bit first indication information as an example, where the base station and terminal support a maximum of 3 SSSGs, {00, 01, 10, 11} correspond to {skipping without PDCCH monitoring, skipping the target time interval 1 for PDCCH monitoring, skipping the target time interval 2 for PDCCH monitoring, and switching to or camping on the target SSSG}, respectively. Among these, skipping without PDCCH monitoring involves the terminal monitoring PDCCH according to the search space configured by the higher layers. When the first indication information is "11", the second information can be read to confirm the SSSG to which the terminal will subsequently switch or camp.

[0194] The specific second information can be any of the following methods:

[0195] 1. The second piece of information is the addition of a new information field to the DCI signaling;

[0196] For example, add 2 bits of information {00, 01, 10, 11} to the DCI to indicate {not listening to SSSG, staying or switching to SSSG0, staying or switching to SSSG1, staying or switching to SSSG2} respectively. The second signaling carrying the second information can be the same DCI as the first indication information, or it can be a different DCI.

[0197] When the first indication information is "11", the second information can be read on the second signaling to confirm the SSSG to be stationed or switched later.

[0198] 2. The second piece of information is the redefinition instruction for reusing existing information fields in DCI signaling;

[0199] For example, the second signaling carrying the second information can be a scheduled DCI and / or an unscheduled DCI and / or a power-saving signal. Taking the scheduled DCI as an example, the SCell sleep indication information field in the DCI can be redefined as a specific SSSG indication in the following way.

[0200] When the CIF field is not 0, the SCell sleep indicator field can be used as a search space set group switching indicator and / or SCell sleep indicator; when the CIF field is 0, the SCell sleep indicator field can be used to indicate the sleep behavior of the SCell. Taking two bits of the second information as an example, {00, 01, 10, 11}, they are used to indicate {not listening to SSSG, staying or switching to SSSG0, staying or switching to SSSG1, staying or switching to SSSG2}, respectively. When the first indicator information is "11", the second information can be read on the second signaling to confirm the SSSG to stay or switch to later.

[0201] 3. The second information is carried in MAC signaling, and MAC signaling is the second signaling;

[0202] For example, the MAC CE indicates the target SSSG, which can be a bit mapping method, where different bits correspond to different SSSGs, or it can be a specific SSSG indication.

[0203] When the first indication information is "11", the second information can be read on the second signaling to confirm the SSSG to be stationed or switched later.

[0204] 4. The second information is carried in RRC signaling, and RRC signaling is the second signaling.

[0205] For example, RRC signaling configures the target SSSG and can also configure timers associated with the SSSG. When the first indication information is "11", the second information can be read on the second signaling, and the SSSG to be camped or switched later can be confirmed according to the RRC parameter configuration.

[0206] The terminal receives the second information and downlink signaling carrying the first indication information. Based on the second information, it learns the corresponding PDCCH monitoring adaptive behavior of the terminal indicated by the first indication information, thereby achieving the effect of terminal power saving.

[0207] When the first indication information is a PDCCH listening skip target time interval, and the second information is used to indicate that the target time interval is a specific time period, the second information is carried by the second downlink signaling, such as DCI / MAC CE / RRC signaling.

[0208] Taking a 2-bit first indication information as an example, where the base station and terminal support a maximum of 3 SSSGs, {00, 01, 10, 11} correspond to {handover to or camping on target SSSG1, handover to or camping on target SSSG2, handover to or camping on target SSSG3, and PDCCH listening skipping the target time interval}, respectively. When the first indication information is "11", the specific target time interval to skip for PDCCH listening can be indicated by the second information.

[0209] The second information is carried through a second downlink signaling, such as DCI / MAC CE / RRC signaling. Specifically, the second information can be one of the following methods:

[0210] The second piece of information is the addition of a new information field to the DCI signaling;

[0211] For example, add 2 bits of information {00, 01, 10, 11} to the DCI to indicate {PDCCH listening skip target time interval 1, PDCCH listening skip target time interval 2, PDCCH listening skip target time interval 3, PDCCH listening skip target time interval 4} respectively. The second signaling carrying the second information can be the same DCI as the first indication information, or it can be a different DCI.

[0212] The second piece of information is the instruction to redefine existing information fields in DCI signaling;

[0213] For example, the second signaling carrying the second information can be scheduled DCI and / or unscheduled DCI and / or power-saving signals. Taking scheduled DCI as an example, the SCell sleep indication information field in DCI can be redefined as a specific indication of the PDCCH listening skip target time interval under the following conditions.

[0214] When the CIF field is not 0, the SCell sleep indicator field can be used as the PDCCH listener skip target time interval and / or SCell sleep indicator; when the CIF field is 0, the SCell sleep indicator field can be used to indicate the sleep behavior of the SCell. Taking two bits of the second information as an example, {00, 01, 10, 11}, they are used to indicate {PDCCH listener skip target time interval 1, PDCCH listener skip target time interval 2, PDCCH listener skip target time interval 3, PDCCH listener skip target time interval 4}, respectively.

[0215] The second information is carried in MAC signaling, and MAC signaling is the second signaling.

[0216] For example, the MAC CE can indicate the target SSSG in a bit mapping manner, where different bits correspond to different PDCCH listening skip target time intervals, or it can be a specific PDCCH listening skip target time interval indication.

[0217] The second information is carried in RRC signaling, and RRC signaling is the second signaling.

[0218] For example, RRC signaling can configure the target PDCCH listening skip target time interval, and can also configure a timer associated with the PDCCH listening skip target time interval.

[0219] The method for determining PDCCH monitoring adaptive behavior provided in this application combines the first and second information in the PDCCH monitoring adaptive indication information to configure different indication information and determine the PDCCH monitoring adaptive behavior. This method can flexibly indicate different PDCCH monitoring behaviors of the terminal device or switch the PDCCH monitoring behavior, thereby saving the monitoring power consumption of the terminal device and ensuring timely data transmission.

[0220] Optionally, the first indication information does not include the configuration of the default or initial SSSG, and the second information is used to indicate the PDCCH listening adaptive behavior based on the first indication information and the corresponding second information when the default or initial SSSG is used, including:

[0221] Based on the first indication information and the corresponding second information, it is determined whether to switch to or remain in the default or initial SSSG.

[0222] Specifically, when the terminal device receives the first indication information, if it cannot revert to the normal PDCCH listening state (i.e., skip PDCCH listening) or switch to or remain in the default or initial SSSG state, then the first indication information does not include the configuration of the default or initial SSSG. The terminal device then sends a second message through the network-side device, which indicates the default or initial SSSG. This determines that the terminal device has switched to or remains in the default or initial SSSG state, meaning that the terminal device can revert to the normal PDCCH listening state, i.e., perform PDCCH listening according to the search space configuration.

[0223] Optionally, the first indication information cannot indicate that PDCCH listening should not be enabled and skipped. The second information is used to indicate that when PDCCH listening is not enabled and skipped, the adaptive behavior of PDCCH listening is determined based on the first indication information and the corresponding second information, including:

[0224] Based on the first indication information and the corresponding second information, it is determined that PDCCH listening should not be enabled and should be skipped.

[0225] Specifically, if the terminal device receives the first indication information and cannot revert to the normal PDCCH listening state (i.e., not enable PDCCH listening skipping) or switch to or remain in the default or initial SSSG state, it may be that the first indication information cannot indicate not enabling PDCCH listening skipping. By using the second information sent by the network-side device to indicate not enabling PDCCH listening skipping, it is determined that the terminal device does not enable PDCCH listening skipping, meaning the terminal device can revert to the normal PDCCH listening state, i.e., perform PDCCH listening according to the search space configuration.

[0226] Optionally, the second information is used to indicate the default or initial SSSG, or the second information is used to indicate skipping PDCCH listening without enabling it. Specific implementation methods include one or a combination of the following:

[0227] The scheduling data field in the downlink signaling is a specific configuration, the newly added or specific bit information in the downlink signaling is the target configuration information, or the redefinition indication of the existing information field in the downlink signaling.

[0228] Specifically, if the terminal device cannot revert to the normal PDCCH listening state based solely on the first indication information, i.e., it performs PDCCH listening according to the search space configuration, and the second information indicates the revert, there are two specific scenarios.

[0229] Scenario 1: When the first indication information does not include an indication to allow the terminal device to fall back to the normal PDCCH listening state, the second information is used to indicate the default or initial SSSG. The second information can be sent via downlink signaling, such as DCI signaling, and the specific implementation methods include any one or a combination of the following:

[0230] The scheduling data field in the downlink signaling is a specific configuration, the newly added or specific bit information in the downlink signaling is the target configuration information, or the redefinition indication of the existing information field in the downlink signaling.

[0231] Taking the 2-bit first indication information as an example, where the base station and terminal support a maximum of 3 SSSGs, {00, 01, 10, 11} correspond to {PDCCH listening skipping without enabling, PDCCH listening skipping target time interval, switching to or camping on target SSSG#1, and switching to or camping on target SSSG#2}, respectively. Among these, the terminal listening to PDCCH without enabling PDCCH listening skipping performs PDCCH listening according to the search space configured by the higher layers. Target SSSG#1 and target SSSG#2 are any two of {SSSG0, SSSG1, SSSG2}.

[0232] Based on this, the specific indication methods for {target SSSG#1 and target SSSG#2} include one or more of the following combinations:

[0233] 1) The terminal requires the configuration of a default SSSG or an initial SSSG, such as SSSG0, which is the SSSG0 that must be configured.

[0234] If {Target SSSG#1 and Target SSSG#2} have a default SSSG or an initial SSSG, the terminal switches to or resides in the target SSSG according to the information indicated by the first instruction information.

[0235] If {target SSSG#1 and target SSSG#2} are not configured with a default SSSG or an initial SSSG, such as SSSG0, then alternatively, a second piece of information can be used to indicate the default or initial SSSG. This includes one or more combinations of the following:

[0236] The second message is the rollback DCI, where the scheduling data field is all zeros, all 1s, or a specific configuration. When the terminal receives the second message, it rolls back to SSSG0.

[0237] The second information is an addition of 1 to N bits to the unscheduled DCI. Upon receiving the second information, the terminal reverts to SSSG0.

[0238] The second information is redefining the existing information fields in the scheduling DCI. That is, if a certain limited configuration occurs, the terminal will fall back to SSSG0 when it receives the second information.

[0239] 2) If {SSSG0, SSSG1, SSSG2} is not limited to a default SSSG or an initial SSSG, then the terminal can reside in any SSSG.

[0240] Scenario 2: When the first instruction information does not include an instruction to revert the terminal device to the normal PDCCH listening state, the second information is used to indicate that PDCCH listening skipping should not be enabled. For example, if the first instruction information does not include an instruction to revert to "PDCCH listening skipping should not be enabled", the second information assists in indicating the reversion to "PDCCH listening skipping should not be enabled".

[0241] The second information can be sent via downlink signaling, such as DCI signaling. Specific implementation methods include any one or a combination of the following:

[0242] The second message is a rollback DCI, where the scheduling data field is all zeros, all 1s, or a specific configuration. When the terminal receives the second message, it rolls back to skipping PDCCH listening.

[0243] The second information is an addition of 1 to N bits to the unscheduled DCI. Upon receiving the second information, the terminal reverts to skipping the PDCCH monitoring step.

[0244] The second information is to redefine the existing information fields in the scheduling DCI. That is, if a certain limited configuration occurs, the terminal will fall back to skipping the PDCCH listening if it receives the second information.

[0245] The method for determining PDCCH monitoring adaptive behavior provided in this application combines the first and second information in the PDCCH monitoring adaptive indication information to configure different indication information and determine the PDCCH monitoring adaptive behavior. This method can flexibly indicate different PDCCH monitoring behaviors of the terminal device or switch the PDCCH monitoring behavior, thereby saving the monitoring power consumption of the terminal device and ensuring timely data transmission.

[0246] Optionally, determining the PDCCH listening adaptive behavior based on the indication information includes:

[0247] If the target SSSG has been pre-configured as a specific SSSG, then based on the first indication information, it is determined that the target SSSG to switch to or reside in is the pre-configured specific SSSG;

[0248] If the PDCCH listening skip target time interval has been pre-configured as the first time interval, then based on the first indication information, a specific time period of the PDCCH listening skip target time interval is determined as the pre-configured first time interval.

[0249] Specifically, when the indication information for PDCCH sniffing adaptation only includes the first indication information, and a specific SSSG associated with sniffing skip has been pre-configured through higher-layer signaling or protocol, then the specific SSSG is the target SSSG to which the terminal device switches or resides.

[0250] Similarly, if a specific time period for skipping PDCCH listening is pre-configured through higher-level signaling or protocols, then the target time period for the terminal device to skip PDCCH listening is that specific time period. For example, if the specific time period is X, then the time period for the terminal to skip PDCCH listening is X, where X is greater than or equal to 0.

[0251] Optionally, when the second information is the terminal device's capability for PDCCH monitoring adaptation or the terminal device's preference information, the first indication information is configured based on the second information.

[0252] Specifically, the configuration of the first indication information can be determined based on the terminal device's capabilities or preferences. The terminal device's capabilities refer to its adaptive capabilities regarding PDCCH monitoring, such as whether it supports PDCCH monitoring skipping or SSSG handover. The terminal device's preferences represent its preferred choices for different network environments. For example, if it needs to fall back to normal PDCCH monitoring, this can be achieved by including disabling PDCCH monitoring skipping or switching the SSSG to the default or initial SSSG in the first indication information. If the terminal device reports a preference of disabling PDCCH monitoring skipping, the base station will consider this preference and configure the first indication information to disabling PDCCH monitoring skipping.

[0253] The method for determining PDCCH monitoring adaptive behavior provided in this application combines the first and second information in the PDCCH monitoring adaptive indication information, and comprehensively considers the actual capabilities and preferences of the terminal device to configure different indication information and determine the PDCCH monitoring adaptive behavior. This can flexibly indicate different PDCCH monitoring behaviors of the terminal device, or switch the PDCCH monitoring behavior, thereby saving the monitoring power consumption of the terminal device and ensuring timely data transmission.

[0254] Optionally, the first indication information is configured based on the second information, and the specific method includes any one or a combination of the following:

[0255] If the second information indicates that only PDCCH listening skipping is supported, then the first indication information is an indication of the relevant behavior for PDCCH listening skipping; or

[0256] If the second information pertains to an SSSG handover other than Rel-16, then the first indication information is an indication of SSSG handover-related behavior; or

[0257] If the second information supports PDCCH listening skip and Rel-16 SSSG switching, then the first indication is a combined indication of PDCCH listening skip and SSSG switching.

[0258] The SSSG switching of Rel-16 includes switching to or residing in SSSG0 and switching to or residing in SSSG1.

[0259] Specifically, the second information can be third information sent by the terminal, used to notify the base station of the specific configuration of the first indication information. Here, the third information can be the capability information of the terminal device (UE), or the preference information of the terminal device, etc. The base station configures the first indication information for the terminal based on the third information. Specific examples include one or more combinations of the following:

[0260] a) If the third information only supports PDCCH listening skip, then the first indication information is a behavior indication related to PDCCH listening skip; if the first indication information is other indication information related to SSSG switching, then the terminal device does not support it, or falls back to the normal PDCCH listening behavior.

[0261] b) If the third information capability only supports SSSG handover for Rel-17, then the first indication information is an SSSG handover related behavior indication. If the first indication information is other indication information related to PDCCH listening skipping, then the terminal device will not perform any one or more combinations of PDCCH listening skipping related behaviors, or will fall back to normal listening behavior. Here, PDCCH listening skipping related behaviors include one or more of the target time intervals for PDCCH listening skipping, and are not limited to one target time interval.

[0262] c) If the third information capability supports PDCCH snooping skipping and Rel-16 SSSG handover, then the first indication information is PDCCH snooping skipping and / or SSSG handover. If the first indication information contains an SSSG indication other than Rel-16, the terminal will not perform the corresponding SSSG2 behavior handover, or will fall back to the normal snooping behavior. SSSG handover related behaviors include: switching to or residing in a target SSSG, not limited to a single target SSSG.

[0263] The method for determining PDCCH monitoring adaptive behavior provided in this application combines the first and second information in the PDCCH monitoring adaptive indication information, and comprehensively considers the actual capabilities and preferences of the terminal device to configure different indication information and determine the PDCCH monitoring adaptive behavior. This can flexibly indicate different PDCCH monitoring behaviors of the terminal device, or switch the PDCCH monitoring behavior, thereby saving the monitoring power consumption of the terminal device and ensuring timely data transmission.

[0264] Figure 2 This is a second flowchart illustrating the method for determining PDCCH listening adaptive behavior provided in this application embodiment; as follows: Figure 2 As shown, this application provides a method for determining PDCCH snooping adaptive behavior, applied to a network-side device, including:

[0265] Step 201: Send PDCCH listening adaptive indication information, the PDCCH listening adaptive indication information including first indication information.

[0266] The first indication information is any one of the following: not enabling PDCCH listening skip, PDCCH listening skip target time interval, and switching to or residing in the target search space group SSSG; the first indication information is used to determine the PDCCH listening adaptive behavior.

[0267] Specifically, network monitoring devices, such as base stations, can send PDCCH monitoring and adaptive indication information to terminal devices to instruct the terminal devices on their PDCCH monitoring and adaptive behavior.

[0268] The PDCCH monitoring adaptive indication information includes first indication information, which can be any one or a combination of several of the following: {do not enable PDCCH monitoring skip, PDCCH monitoring skip target time interval, switch to or reside in the target search space set SSSG}.

[0269] Among them, skipping the target time interval without enabling PDCCH listening means skipping without enabling PDCCH listening;

[0270] Enabling PDCCH listening to skip the target time interval includes two cases:

[0271] If no specific time interval is given, it means that the PDCCH listener skips the target time interval. The specific time interval is uncertain and may be one or more combinations.

[0272] If a specific time interval is given, it represents any one or more combinations of a set {PDCCH listener skip target time interval 1, ..., PDCCH listener skip target time interval N}, where N is greater than or equal to 1.

[0273] Similarly, switching to or residing in the target search space set SSSG may include the following meanings:

[0274] If the target search space set is not a definite SSSG, it means that the behavior of switching to or residing in the target search space set SSSG is uncertain.

[0275] 2. If the target search space set is a specific SSSG, then it represents a combination of any one or more sets {switching to or residing in target SSSG0, ..., switching to or residing in target SSSGM}, with an M value greater than or equal to 0.

[0276] The aforementioned first instruction information is sent to the terminal device so that the terminal device can determine its own PDCCH listening adaptive behavior, such as normal PDCCH listening, that is, PDCCH listening according to the search space configuration, or not listening to PDCCH for a certain period of time, or listening to PDCCH in a specific search space set, or switching the search space set SSSG.

[0277] The method for determining PDCCH listening adaptive behavior provided in this application determines PDCCH listening adaptive behavior by configuring different PDCCH listening adaptive indication information. This can flexibly instruct different PDCCH listening behaviors of the terminal device or switch the PDCCH listening behavior, thereby saving the listening power consumption of the terminal device and ensuring timely data transmission.

[0278] Optionally, the PDCCH listening adaptive behavior includes at least: not enabling PDCCH listening skip, PDCCH listening skipping target time interval, and switching to or residing in the target SSSG;

[0279] Wherein, the target time interval is a specific time period, and the target SSSG is a specific SSSG.

[0280] Specifically, based on different PDCCH listening adaptive indication information, the determined PDCCH listening adaptive behavior includes at least the following:

[0281] If PDCCH listening is not enabled, the terminal device will perform normal PDCCH listening, i.e., PDCCH listening will be performed according to the search space configuration.

[0282] PDCCH listening skips a specific time period of the target time interval, meaning that the terminal device does not perform PDCCH listening during a specific time period.

[0283] Switching to or residing in the target SSSG, where the target SSSG is a specific SSSG, indicates two scenarios:

[0284] Scenario 1: The terminal switches to a specific SSSG and performs PDCCH listening according to the listening opportunities configured in the specific SSSG. The specific SSSG is different from the SSSG originally configured for the terminal device.

[0285] Scenario 2: The terminal device resides in a specific SSSG and performs PDCCH listening according to the listening opportunities configured in the specific SSSG. The specific SSSG is the same as the SSSG originally configured for the terminal device.

[0286] The method for determining PDCCH listening adaptive behavior provided in this application determines PDCCH listening adaptive behavior by configuring different PDCCH listening adaptive indication information. This can flexibly instruct different PDCCH listening behaviors of the terminal device or switch the PDCCH listening behavior, thereby saving the listening power consumption of the terminal device and ensuring timely data transmission.

[0287] Optionally, the PDCCH monitoring adaptive indication information further includes second information, and the first indication information and the second information have the following correspondence:

[0288] If the first indication information is to switch to or reside in the target SSSG, then the second information indicates that the target SSSG is a specific SSSG;

[0289] If the first indication information is a PDCCH listening skip target time interval, then the second information is an indication that the target time interval is a specific time period;

[0290] If the first indication information does not include the configuration of the default or initial SSSG, then the second information is used to indicate the default or initial SSSG;

[0291] If the first indication information cannot indicate that PDCCH listening should not be enabled and skipped, then the second information is used to indicate that PDCCH listening should not be enabled and skipped.

[0292] The first indication information and the corresponding second information are used to determine the PDCCH monitoring adaptive behavior.

[0293] Specifically, the PDCCH listening adaptation indication information sent by the network-side device includes first indication information and second information. The second information is used to provide auxiliary indication of the terminal's specific PDCCH listening adaptation behavior. For example, if the target time interval or target SSSG is uncertain in the first indication information, or if it does not include the relevant configuration for returning to the normal PDCCH listening state, the second information can indicate which specific time interval, or which specific SSSG, or indicate the configuration for returning to the normal PDCCH listening state (configuration of default or initial SSSG, or skipping PDCCH listening if not enabled).

[0294] The combined indication information and the second information mentioned above indicate the PDCCH monitoring adaptive behavior of the terminal device, specifically including:

[0295] When the first indication is to switch to or reside in the target SSSG, the second indication is that the target SSSG is a specific SSSG;

[0296] If the first indication information is that the PDCCH listening skips the target time interval, then the second information indicates that the target time interval is a specific time period;

[0297] If the first indication information does not include the configuration of the default or initial SSSG, then the second information is used to indicate the default or initial SSSG;

[0298] If the first indication information cannot indicate that PDCCH listening should not be enabled and skipped, then the second information is used to indicate that PDCCH listening should not be enabled and skipped.

[0299] The network testing device sends the aforementioned first instruction information and second information to the terminal device so that the terminal device can determine its specific PDCCH listening adaptive behavior.

[0300] The method for determining PDCCH monitoring adaptive behavior provided in this application combines the first and second information in the PDCCH monitoring adaptive indication information to configure different indication information and determine the PDCCH monitoring adaptive behavior. This method can flexibly indicate different PDCCH monitoring behaviors of the terminal device or switch the PDCCH monitoring behavior, thereby saving the monitoring power consumption of the terminal device and ensuring timely data transmission.

[0301] Optionally, the configuration of the first indication information is determined based on the terminal device's capabilities related to PDCCH monitoring adaptation or the terminal device's preference information configured in the second information.

[0302] Specifically, the network testing equipment comprehensively considers the capabilities or preferences of the terminal devices and sends appropriate initial instructions to them accordingly.

[0303] Among these, terminal device capabilities refer to the terminal device's adaptive capabilities regarding PDCCH monitoring, such as whether the terminal device supports PDCCH monitoring skipping and SSSG handover. Terminal device preference information refers to the choices the terminal device prioritizes for different network environments. For example, if it needs to fall back to normal PDCCH monitoring, this can be achieved by including "disable PDCCH monitoring skipping" in the first indication information, or by switching the SSSG to the default or initial SSSG. If the terminal device reports a preference of "disable PDCCH monitoring skipping," the base station will consider this preference and configure the first indication information to "disable PDCCH monitoring skipping."

[0304] The method for determining PDCCH monitoring adaptive behavior provided in this application combines the first and second information in the PDCCH monitoring adaptive indication information, and comprehensively considers the actual capabilities and preferences of the terminal device to configure different indication information and determine the PDCCH monitoring adaptive behavior. This can flexibly indicate different PDCCH monitoring behaviors of the terminal device, or switch the PDCCH monitoring behavior, thereby saving the monitoring power consumption of the terminal device and ensuring timely data transmission.

[0305] Optionally, the method for determining the configuration of the first indication information based on the terminal device's adaptive capabilities regarding PDCCH monitoring or the terminal device's preference information configured in the second information includes one or more of the following combinations:

[0306] If the second information indicates that only PDCCH listening skipping is supported, then the first indication information is an indication of the relevant behavior for PDCCH listening skipping; or

[0307] If the second information pertains to an SSSG handover other than Rel-16, then the first indication information is an indication of SSSG handover-related behavior; or

[0308] If the second information supports PDCCH listening skip and Rel-16 SSSG switching, then the first indication is a combined indication of PDCCH listening skip and SSSG switching.

[0309] The SSSG switching of Rel-16 includes switching to or residing in SSSG0 and switching to or residing in SSSG1.

[0310] Specifically, the second information can be third information sent by the terminal, used to notify the base station of the specific configuration of the first indication information. Here, the third information can be the capability information of the terminal device (UE), or the preference information of the terminal device, etc. The base station configures the first indication information for the terminal based on the third information. Specific examples include one or more combinations of the following:

[0311] a) If the third information only supports PDCCH listening skip, then the first indication information is a behavior indication related to PDCCH listening skip; if the first indication information is other indication information related to SSSG switching, then the terminal device does not support it, or falls back to the normal PDCCH listening behavior.

[0312] b) If the third information capability only supports SSSG handover for Rel-17, then the first indication information is an SSSG handover related behavior indication. If the first indication information is other indication information related to PDCCH listening skipping, then the terminal device will not perform any one or more combinations of PDCCH listening skipping related behaviors, or will fall back to normal listening behavior. Here, PDCCH listening skipping related behaviors include one or more of the target time intervals for PDCCH listening skipping, and are not limited to one target time interval.

[0313] c) If the third information capability supports PDCCH snooping skipping and Rel-16 SSSG handover, then the first indication information is PDCCH snooping skipping and / or SSSG handover. If the first indication information contains an SSSG indication other than Rel-16, the terminal will not perform the corresponding SSSG2 behavior handover, or will fall back to the normal snooping behavior. SSSG handover related behaviors include: switching to or residing in a target SSSG, not limited to a single target SSSG.

[0314] The method for determining PDCCH monitoring adaptive behavior provided in this application combines the first and second information in the PDCCH monitoring adaptive indication information, and comprehensively considers the actual capabilities and preferences of the terminal device to configure different indication information and determine the PDCCH monitoring adaptive behavior. This can flexibly indicate different PDCCH monitoring behaviors of the terminal device, or switch the PDCCH monitoring behavior, thereby saving the monitoring power consumption of the terminal device and ensuring timely data transmission.

[0315] Optionally, the transmission of PDCCH listening adaptive indication information including first indication information includes:

[0316] The PDCCH monitoring adaptive indication information also includes second information. Furthermore, if PDCCH monitoring skipping related information and / or SSSG handover related information are pre-configured, the existence of the second information and the first indication information has the following correspondence:

[0317] If the second information indicates pre-configured PDCCH listening skip related information, then the first indication information and the pre-configured PDCCH listening skip related information correspond one-to-one;

[0318] If the second information indicates pre-configured SSSG handover related information, then the first indication information and the pre-configured SSSG handover related information correspond one-to-one;

[0319] The pre-configured PDCCH listening skip information includes: not enabling PDCCH listening skip, and / or a set of target time intervals for PDCCH listening skip;

[0320] The pre-configured SSSG switching information includes: not performing SSSG listening, and / or switching to or residing in the target SSSG set.

[0321] Specifically, when a network testing device sends an indication message for PDCCH listening adaptation, which includes a first indication message and a second message, if higher-layer signaling or protocol specifies that PDCCH listening skipping information and SSSG handover information have been pre-configured, the terminal device determines the PDCCH listening adaptation behavior of the terminal device based on the first indication message, the second message, and the aforementioned pre-configured information.

[0322] The specific method for determining the terminal device and the method for determining the PDCCH listening adaptive behavior provided in the embodiments of this application are the same when applied to the terminal device, and the same technical effects are achieved, so they will not be described again here.

[0323] The method for determining PDCCH monitoring adaptive behavior provided in this application combines the first and second information in the PDCCH monitoring adaptive indication information to configure different indication information and determine the PDCCH monitoring adaptive behavior. This method can flexibly indicate different PDCCH monitoring behaviors of the terminal device or switch the PDCCH monitoring behavior, thereby saving the monitoring power consumption of the terminal device and ensuring timely data transmission.

[0324] In this application, network-side equipment, such as a base station, carries first indication information through second information and / or downlink signaling to instruct the terminal on corresponding PDCCH monitoring adaptive behavior, thereby achieving the effect of terminal power saving. The first indication information can be either newly added N bits of information in the downlink signaling or redefined N bits of information in the downlink signaling.

[0325] The second information is used to assist the first indication information in providing specific instructions on the terminal's PDCCH adaptive behavior. It is carried by DCI, MAC, or RRC signaling, and specifically includes one or more of the following schemes in combination:

[0326] Option 1: When the first indication information indicates "PDCCH monitoring skip" or "SSSG handover," the second information is used to provide auxiliary indication of the terminal's specific PDCCH monitoring adaptive behavior, including {PDCCH monitoring skip target time interval i}, where i is greater than or equal to 1 and less than or equal to N, or {switching to or residing in a target SSSG within the target SSSG set}. The second information is specifically carried through DCI / MAC / RRC signaling and can be one or a combination of the following methods:

[0327] A new information field has been added to the DCI signaling;

[0328] In DCI signaling, existing information fields are reused for redefinition instructions;

[0329] MAC CE provides instructions;

[0330] RRC signaling configuration.

[0331] Option 2: When the first indication information is only used to indicate {PDCCH listening skip target time interval}, or {switching to or residing in one of the target SSSG sets}, the second information is used to indicate that the terminal falls back to the normal listening behavior, the default listening behavior, or the initial listening behavior, such as: behavior 1 and / or behavior 2. The second information can be a DCI other than the scheduling DCI carrying the PDCCH listening adaptive indication, specifically, it can be one of the following methods:

[0332] By reverting the DCI scheduling data field to all zeros, all 1s, or a specific configuration, the behavior can be reverted to the normal listening behavior, the default listening behavior, or the initial listening behavior.

[0333] By adding 1 to N bits to the unscheduled DCI, the terminal can be instructed to fall back to the normal listening behavior, the default listening behavior, or the initial listening behavior.

[0334] By redefining the existing information domains in the DCI, that is, when a certain limited configuration occurs, the terminal is instructed to fall back to the normal listening behavior, the default listening behavior, or the initial listening behavior.

[0335] Option 3: When the first indication information is only used to indicate a type of PDCCH sniffing adaptive behavior, the second information is UE capability information sent by the UE or UE preference information. The third information indicates the terminal's support or preference for PDCCH sniffing skipping, SSSG switching, or target SSSG.

[0336] If the terminal can support two PDCCH listening adaptive behaviors, and the second information is that the terminal prefers to skip PDCCH listening, then the first indication information is the relevant behavior indication for skipping PDCCH listening.

[0337] If the third information capability only supports SSSG handover for Rel-17, then the first indication information is an indication of SSSG handover related behavior.

[0338] If the third information capability supports PDCCH listening skip and Rel-16 SSSG switching, then the first indication information is a joint indication of PDCCH listening skip and SSSG switching.

[0339] Specifically, PDCCH listener skipping behaviors include: disabling PDCCH listener skipping and skipping one or more of the following target time intervals, not limited to a single target time interval. SSSG switching behaviors include: switching to or residing in a target SSSG, not limited to a single target SSSG.

[0340] The following specific embodiments illustrate the method for determining PDCCH listening adaptive behavior provided in this application.

[0341] Scenario 1: The first indication message includes switching to or residing in a target SSSG, and the target SSSG is uncertain. For example, the first indication message indicates {do not enable PDCCH listening skip, PDCCH listening skip target time interval 1, ..., PDCCH listening skip target time interval N (N is greater than or equal to 1) and / or switch to or reside in a target SSSG}. The target SSSG set is any one of the configured SSSGs, which can be the default SSSG, the initial SSSG, or a newly added SSSG based on the Rel-16 standard. Here, if only one PDCCH listening skip target time interval is in the above indication message set, it is equivalent to enabling PDCCH listening skip. Switching to or residing in a target SSSG means switching to or residing in a configured target SSSG, and can also indicate SSSG switching behavior.

[0342] Taking the 2-bit first indication information as an example, where the base station and terminal support a maximum of 3 SSSGs, {00, 01, 10, 11} correspond to {PDCCH listening skipping not enabled, PDCCH listening skipping target time interval 1, PDCCH listening skipping target time interval 2, switching to or camping on the target SSSG}, respectively. Among these, when PDCCH listening skipping is disabled, the terminal performs PDCCH listening according to the search space configured by the higher layers.

[0343] The PDCCH listening skipping behavior in the first indication information can be applied to a specific configured SSSG, such as the current SSSG or an SSSG associated with listening skipping as specified in the protocol, i.e., all or part of the search space set in that SSSG, requiring a skipping time interval according to the corresponding first indication information. Different PDCCH listening skipping target time intervals N in the first indication information can be used for the same SSSG or applied to different SSSGs. For example, PDCCH listening skipping target time interval 1 or PDCCH listening skipping target time interval 2 can only be used for at least one of SSSG0, SSSG1, and SSSG2. The target SSSG can be SSSG0, SSSG1, or SSSG2, configured through higher-layer signaling or specified by the protocol. When the base station sends the first indication information as "01" or "10", it instructs the terminal not to perform PDCCH listening on the specific SSSG. When the first indication information is "11", it instructs the terminal to only listen to the PDCCH on the target SSSG, listening according to the search space configuration on that SSSG. The target SSSG can be SSSG0, SSSG1, or SSSG2, specifically pre-configured through higher-layer signaling or specified by the protocol.

[0344] The PDCCH listening skipping behavior in the first indication information can be applied to the currently active BWP. That is, all designated PDCCHs configured on the currently active BWP, taking PDCCHs in the Type 3 public search space or UE-specific search space as examples, must skip PDCCH listening for the target time interval. When the base station sends the first indication information as "01" or "10", it instructs the terminal not to perform designated PDCCH listening on the currently active BWP, with skip times of target time interval 1 or target time interval 2, respectively. When the first indication information is "11", it instructs the terminal to only listen to the PDCCH on the target SSSG, according to the search space configuration on that SSSG. The target SSSG can be SSSG0, SSSG1, or SSSG2, specifically configured through higher-layer signaling or protocol specifications.

[0345] The first indication information PDCCH listening skipping behavior applies only to the search space set where the first indication information is located. When the base station sends the first indication information as "01" or "10", it instructs the terminal not to listen to the specified PDCCH on the current search space set, with the skip time being target time interval 1 or target time interval 2, respectively. When the first indication information is "11", it instructs the terminal to listen only to the PDCCH on the target SSSG, according to the search space configuration on that SSSG. The target SSSG can be SSSG0, SSSG1, or SSSG2, specifically configured through higher-layer signaling or protocol specifications.

[0346] 1) Switch to or reside in the target SSSG as a pre-configured SSSG, where the pre-configured SSSG can be configured by higher-level signaling or as specified by the protocol.

[0347] The terminal receives downlink signaling carrying first indication information and learns the corresponding PDCCH monitoring adaptive behavior of the terminal based on the first indication information, thereby achieving the effect of terminal power saving.

[0348] 2) The switch to or reside in the target SSSG is determined by the second information indication. Taking a maximum of three SSSGs as an example, the second information auxiliary indication switches to or resides in at least one of {SSSG0, SSSG1, SSSG2}. The second information is carried through the second downlink signaling, such as DCI / MAC CE / RRC signaling. Specifically, the second information can be one of the following methods:

[0349] (1) The second information is the addition of a new information field in the DCI signaling;

[0350] For example, add 2 bits of information {00, 01, 10, 11} to the DCI to indicate {not listening to SSSG, staying or switching to SSSG0, staying or switching to SSSG1, staying or switching to SSSG2} respectively. The second signaling carrying the second information can be the same DCI as the first indication information, or it can be a different DCI.

[0351] When the first indication information is "11", the second information can be read on the second signaling to confirm the SSSG to be stationed or switched later.

[0352] (2) The second information is the redefinition instruction for reusing existing information fields in DCI signaling;

[0353] For example, the second signaling carrying the second information can be a scheduled DCI and / or an unscheduled DCI and / or a power-saving signal. Taking the scheduled DCI as an example, the SCell sleep indication information field in the DCI can be redefined as a specific SSSG indication under the following conditions.

[0354] When the CIF field is not 0, the SCell sleep indicator field can be used as a search space set group switching indicator and / or SCell sleep indicator; when the CIF field is 0, the SCell sleep indicator field can be used to indicate the sleep behavior of the SCell. Taking two bits of the second information as an example, {00, 01, 10, 11}, they are used to indicate {not listening to SSSG, staying or switching to SSSG0, staying or switching to SSSG1, staying or switching to SSSG2}, respectively. When the first indicator information is "11", the second information can be read on the second signaling to confirm the SSSG to stay or switch to later.

[0355] (3) The second information is carried in MAC signaling, and MAC signaling is the second signaling;

[0356] For example, the MAC CE indicates the target SSSG, which can be a bit mapping method, where different bits correspond to different SSSGs, or it can be a specific SSSG indication.

[0357] When the first indication information is "11", the second information can be read on the second signaling to confirm the SSSG to be stationed or switched later.

[0358] (4) The second information is carried in RRC signaling, and RRC signaling is the second signaling.

[0359] For example, RRC signaling configures the target SSSG and can also configure timers associated with the SSSG. When the first indication information is "11", the second information can be read on the second signaling, and the SSSG to be camped or switched later can be confirmed according to the RRC parameter configuration.

[0360] The terminal receives the second information and downlink signaling carrying the first indication information. Based on the second information, it learns the corresponding PDCCH monitoring adaptive behavior of the terminal indicated by the first indication information, thereby achieving the effect of terminal power saving.

[0361] Scenario 2: The first indication information includes a PDCCH listening skip target time interval, and the target time interval is uncertain. For example, the first indication information indicates {Do not enable PDCCH listening skip, PDCCH listening skip target time interval, and / or {Switch to or reside in target SSSG#1, ..., switch to or reside in target SSSG#N}}, where N is greater than or equal to 1. Here, the target SSSG set consisting of target SSSG#N is a subset or the entire set of configured SSSGs. The target SSSG is any SSSG in the target SSSG set, which can be the default SSSG, the initial SSSG, or a newly added SSSG based on the Rel-16 standard. Here, when there is only one PDCCH listening skip target time interval in the above indication information set, it is equivalent to enabling PDCCH listening skip.

[0362] 1. If the PDCCH listening skip target time interval corresponds to a specific target time interval, this target time interval can be configured through higher-layer signaling or specified by the protocol.

[0363] 2. If the target time interval for PDCCH listening skips corresponds to different target time intervals for PDCCH listening skips, optionally, the second information can be used to indicate the different target time intervals for PDCCH listening skips.

[0364] Taking a 2-bit first indication information as an example, where the base station and terminal support a maximum of 3 SSSGs, {00, 01, 10, 11} correspond to {handover to or camping on target SSSG#1, handover to or camping on target SSSG#2, handover to or camping on target SSSG#3, and PDCCH listening skipping target time interval}, respectively. When the first indication information is "11", the specific target time interval to skip for PDCCH listening can be indicated by the second information.

[0365] The second information is carried through a second downlink signaling, such as DCI / MAC CE / RRC signaling. Specifically, the second information can be one of the following methods:

[0366] (1) The second information is the addition of a new information field in the DCI signaling;

[0367] For example, add 2 bits of information {00, 01, 10, 11} to the DCI to indicate {PDCCH listening skip target time interval 1, PDCCH listening skip target time interval 2, PDCCH listening skip target time interval 3, PDCCH listening skip target time interval 4} respectively. The second signaling carrying the second information can be the same DCI as the first indication information, or it can be a different DCI.

[0368] (2) The second information is the redefinition instruction for reusing existing information fields in DCI signaling;

[0369] For example, the second signaling carrying the second information can be scheduled DCI and / or unscheduled DCI and / or power-saving signals. Taking scheduled DCI as an example, the SCell sleep indication information field in DCI can be redefined as a specific indication of the PDCCH listening skip target time interval under the following conditions.

[0370] When the CIF field is not 0, the SCell sleep indicator field can be used as the PDCCH listener skip target time interval and / or SCell sleep indicator; when the CIF field is 0, the SCell sleep indicator field can be used to indicate the sleep behavior of the SCell. Taking two bits of the second information as an example, {00, 01, 10, 11}, they are used to indicate {PDCCH listener skip target time interval 1, PDCCH listener skip target time interval 2, PDCCH listener skip target time interval 3, PDCCH listener skip target time interval 4}, respectively.

[0371] (3) The second information is carried in MAC signaling, and MAC signaling is the second signaling;

[0372] For example, the MAC CE can indicate the target SSSG in a bit mapping manner, where different bits correspond to different PDCCH listening skip target time intervals, or it can be a specific PDCCH listening skip target time interval indication.

[0373] (4) The second information is carried in RRC signaling, and RRC signaling is the second signaling.

[0374] For example, RRC signaling can configure the target PDCCH listening skip target time interval, and can also configure a timer associated with the PDCCH listening skip target time interval.

[0375] Scenario 3: The first indication information does not include an indication to fall back to the normal or normal PDCCH listening state. That is, the first indication information does not include the default or initial SSSG configuration or the first indication information cannot indicate that PDCCH listening is not enabled and skipped.

[0376] 3.1 When the first indication information does not include the configuration of the default or initial SSSG, the second information is used to indicate the default or initial SSSG;

[0377] Taking the 2-bit first indication information as an example, where the base station and terminal support a maximum of 3 SSSGs, {00, 01, 10, 11} correspond to {PDCCH listening skipping without enabling, PDCCH listening skipping target time interval, switching to or camping on target SSSG#1, and switching to or camping on target SSSG#2}, respectively. Among these, the terminal listening to PDCCH without enabling PDCCH listening skipping performs PDCCH listening according to the search space configured by the higher layers. Target SSSG#1 and target SSSG#2 are any two of {SSSG0, SSSG1, SSSG2}.

[0378] Based on this, the specific indication methods for {target SSSG#1 and target SSSG#2} include one or more of the following combinations:

[0379] (1) The terminal requires the configuration of a default SSSG or an initial SSSG, such as SSSG0, which is the SSSG0 that must be configured.

[0380] If {Target SSSG#1 and Target SSSG#2} have a default SSSG or an initial SSSG, the terminal switches to or resides in the target SSSG according to the information indicated by the first instruction information.

[0381] If {target SSSG#1 and target SSSG#2} are not configured with a default SSSG or an initial SSSG, such as SSSG0, then alternatively, a second piece of information can be used to indicate the default or initial SSSG. This includes one or more combinations of the following:

[0382] The second message is the rollback DCI, where the scheduling data field is all zeros, all 1s, or a specific configuration. When the terminal receives the second message, it rolls back to SSSG0.

[0383] The second information is an addition of 1 to N bits to the unscheduled DCI. Upon receiving the second information, the terminal reverts to SSSG0.

[0384] The second information is redefining the existing information fields in the scheduling DCI. That is, if a certain limited configuration occurs, the terminal will fall back to SSSG0 when it receives the second information.

[0385] (2) If {SSSG0, SSSG1, SSSG2} is not limited to a default SSSG or an initial SSSG, that is, the terminal can reside in any SSSG.

[0386] 3.2 When the first indication information cannot indicate that PDCCH listening skipping is not enabled, the second information is used to indicate that PDCCH listening skipping is not enabled. Specifically, this includes one or more combinations of the following methods:

[0387] The second message is a rollback DCI, where the scheduling data field is all zeros, all 1s, or a specific configuration. When the terminal receives the second message, it rolls back to skipping PDCCH listening.

[0388] The second information is an addition of 1 to N bits to the unscheduled DCI. Upon receiving the second information, the terminal reverts to skipping the PDCCH monitoring step.

[0389] The second information is to redefine the existing information fields in the scheduling DCI. That is, if a certain limited configuration occurs, the terminal will fall back to skipping the PDCCH listening if it receives the second information.

[0390] Scenario 4: If the higher-level signaling or protocol specifies that PDCCH listening skipping information and SSSG handover information have been pre-configured, then the PDCCH listening adaptive behavior of the terminal device is determined based on the first indication information, the second information and the aforementioned pre-configured information.

[0391] The specific determination method is as follows:

[0392] 4.1 The PDCCH listening skip related information in the pre-configuration information of the second information indication includes: not enabling PDCCH listening skip, and a set of PDCCH listening skip target time intervals, for example: {not enabling PDCCH listening skip, PDCCH listening skip target time interval 1, ..., PDCCH listening skip target time interval N-1}, where N is the number of indication information included in the first indication information.

[0393] 4.2 The SSSG switching related information in the pre-configuration information of the second information indication includes: not performing SSSG monitoring, and / or switching to or residing in a set of target SSSGs, for example: {not performing SSSG monitoring, switching to or residing in target SSSG0, ..., switching to or residing in target SSSGM-2}, or {switching to or residing in target SSSG0, ..., switching to or residing in target SSSGM}, where M is the number of indication information included in the first indication information. Not performing SSSG monitoring means not monitoring by search space group, that is, all search spaces configured by RRC must be monitored.

[0394] Taking the 2-bit first indication information as an example, the pre-configured PDCCH listening skip information is {PDCCH listening skip not enabled, PDCCH listening skip target time interval 1, PDCCH listening skip target time interval 2, PDCCH listening skip target time interval 3}. The pre-configured SSSG switching information is {SSSG listening not enabled, switching to or residing in target SSSG0, switching to or residing in target SSSG1, switching to or residing in target SSSG2}.

[0395] If the second information indicates the pre-configured PDCCH listening skip related information, then the {00, 01, 10, 11} of the first indication information correspond to {PDCCH listening skip not enabled, PDCCH listening skip target time interval 1, PDCCH listening skip target time interval 2, PDCCH listening skip target time interval 3} respectively.

[0396] If the second information indicates pre-configured SSSG switching related information, then the {00, 01, 10, 11} of the first indication information correspond to {not performing SSSG listening, switching to or residing in target SSSG0, switching to or residing in target SSSG1, switching to or residing in target SSSG2} respectively.

[0397] Scenario 5: Determine the first instruction information based on the capabilities or preferences of the terminal device.

[0398] The second information can be third information sent by the terminal, used to notify the base station of the specific configuration of the first indication information. Here, the third information can be the capability information of the terminal device (UE), or the preference information of the terminal device, etc. The base station configures the first indication information for the terminal based on the third information. Specific examples include one or more combinations of the following:

[0399] a) If the third information only supports PDCCH listening skip, then the first indication information is a behavior indication related to PDCCH listening skip; if the first indication information is other indication information related to SSSG switching, then the terminal device does not support it, or falls back to the normal PDCCH listening behavior.

[0400] b) If the third information capability only supports SSSG handover for Rel-17, then the first indication information is an SSSG handover related behavior indication. If the first indication information is other indication information related to PDCCH listening skipping, then the terminal device will not perform any one or more combinations of PDCCH listening skipping related behaviors, or will fall back to normal listening behavior. Here, PDCCH listening skipping related behaviors include one or more of the target time intervals for PDCCH listening skipping, and are not limited to one target time interval.

[0401] c) If the third information capability supports PDCCH snooping skipping and Rel-16 SSSG handover, then the first indication information is PDCCH snooping skipping and / or SSSG handover. If the first indication information contains an SSSG indication other than Rel-16, the terminal will not perform the corresponding SSSG2 behavior handover, or will fall back to the normal snooping behavior. SSSG handover related behaviors include: switching to or residing in a target SSSG, not limited to a single target SSSG.

[0402] Optionally, the base station sends second information to indicate the specific indication of the first indication information, which may be one or a combination of the following:

[0403] If the second information is for configuring SSSG switching in Rel-16, then the first indication information is an indication of the relevant behavior of skipping PDCCH listening; or

[0404] If the second information is to configure the target time interval for skipping PDCCH listening, then the first indication information is an indication of the relevant behavior for skipping PDCCH listening.

[0405] The SSSG switching of Rel-16 includes switching to or residing in SSSG0 and switching to or residing in SSSG1.
