[0069] The relevant content involved in the embodiments of this application will be introduced below.

[0070] I. Regarding the switching of Search Space Group (SSG) in Release 16 (R16), or Search Space Set Group (SSSG) switching;

[0071] 1. R16 Search Space Group Switching Mechanism or Technology: R16 introduces two search space groups (SS groups): search space group #0 and #1; and introduces two switching methods: implicit and explicit (supporting dynamic switching of downlink control information DCI 2-0).

[0072] The network can be configured to associate one or more search spaces from Type 3-PDCCH CSS (public search space) set or a USS (terminal-specific search space) set with search space group #0 and / or search space group #1. The following understanding of search spaces and search space sets is the same, and will not be elaborated further here.

[0073] For example, the search space associated with search space group #0 includes all Type3-PDCCH CSS sets; the search space associated with search space group #1 includes all USS sets.

[0074] Therefore, if the terminal is listening to the PDCCH on search space group #1, or in other words, the terminal is listening to the PDCCH on search space group #1, it means that the terminal is listening to the PDCCH corresponding to all search spaces associated with search space group #1. The same understanding applies to search space group #0, so I won't go into details.

[0075] Furthermore, only the Type3-PDCCH CSS set or a USS set is supported for search space group switching. Other types of search spaces are not supported for search space group switching. This means that the terminal must continuously monitor the PDCCH on search spaces other than the aforementioned Type3-PDCCH CSS set or a USS set.

[0076] The terminal PDCCH listening behavior corresponding to search space group #0 is: to listen to PDCCH only on search space group #0, and to stop listening to PDCCH on search space groups other than search space group #0.

[0077] In other words, PDCCH can only be monitored on one search space group at a time.

[0078] The terminal PDCCH listening behavior corresponding to search space group #1 is: to listen to PDCCH only on search space group #1, and to stop listening to PDCCH on search space groups other than search space group #1.

[0079] searchSpaceSwitchTimer (R16 search space group switching timer): Abbreviated as the first timer. The PDCCH listening behavior corresponding to the expiration of the first timer is: switch to search space group #0, and then apply the terminal behavior corresponding to search space group #0 (as above). Here, search space group #0 can be understood as the default search space group.

[0080] Only Type3-PDCCH CSS sets or USS sets can be linked to the two search space groups mentioned above. Other types (such as Type0, 0A, 1, 2, etc.) of CSS sets do not belong to any search space group and are not subject to the search space group switching mechanism. In other words, the terminal will always listen to the PDCCH on it.

[0081] If a search space in a type 3 CSS or USS is not associated with these two search space groups, it means that the terminal cannot skip the PDCCH listening on it by switching search space groups. In other words, the terminal needs to continuously listen to the PDCCH corresponding to this search space.

[0082] 2. Explicit search space group handover procedure (Radio Resource Control (RRC) is equipped with relevant handover instructions based on DCI2-0), including:

[0083] Process 1: Triggering condition for switching from group (search space group) 1 to group 0: Detection of DCI 2-0 indication to switch to group 0.

[0084] Process 2: Triggering condition for switching from group0 to group1: Detection of DCI 2-0 indication to switch to group1 and restart or start the first timer.

[0085] Process 3: Triggering conditions for switching from group1 to group0: the first timer times out, or the COT (Channel Occupied Time) duration ends.

[0086] 3. The implicit search space group switching process (assuming the RRC is not configured with the relevant switching indication of DCI2-0) includes:

[0087] Process 1: Triggering conditions for switching from group0 to group1: The terminal will trigger a switch from group0 to group1 if it detects any DCI format on group0. Furthermore, if any DCI format is detected on any group, the first timer must be restarted.

[0088] Process 2: Triggering conditions for switching from group1 to group0: the first timer times out, or the COT duration ends.

[0089] Among them, a UE (terminal) can be configured with a maximum of 10 search spaces.

[0090] II. Regarding the R17 PDCCH monitoring adaptation solution;

[0091] Specifically, it includes the following two sub-schemes:

[0092] 1. R17 (Release 17) Search Space Group (SSG) Switching, also known as R17 SSSG Switching;

[0093] Unlike the R16 search space group switching, the R17 search space group switching can configure up to three search space groups, namely search space group #0, #1 and #2.

[0094] Furthermore, only the Type3-PDCCH CSS set or a USS set is supported for search space group switching. Other types of search spaces are not supported for search space group switching. This means that the terminal must continuously monitor the PDCCH on search spaces other than the aforementioned Type3-PDCCH CSS set or a USS set.

[0095] The network can be configured to associate one or more search spaces in the Type3-PDCCH CSS set or a USS set with at least one of search space group #0, search space group #1, and search space group #2.

[0096] If the terminal is listening to the PDCCH on search space group #1, or in other words, the terminal is listening to the PDCCH on search space group #1, it means that the terminal is listening to the PDCCH corresponding to all search spaces associated with search space group #1. The same understanding applies to search space groups #0 and #2, so it will not be elaborated further.

[0097] The terminal PDCCH listening behavior corresponding to search space group #0 is: to listen to PDCCH only on search space group #0, and to stop listening to PDCCH on search space groups other than search space group #0.

[0098] In other words, PDCCH can only be monitored on one search space group at a time.

[0099] The terminal PDCCH listening behavior corresponding to search space group #1 is: to listen to PDCCH only on search space group #1, and to stop listening to PDCCH on search space groups other than search space group #1.

[0100] The terminal PDCCH listening behavior corresponding to search space group #2 is: to listen to PDCCH only on search space group #2, and to stop listening to PDCCH on search space groups other than search space group #2.

[0101] searchSpaceSwitchTimer-r17 (R17 search space group switching timer): This is abbreviated as the second timer. The terminal PDCCH listening behavior corresponding to the expiration of the second timer is: switching to search space group #0, and then applying the terminal behavior corresponding to search space group #0 (as above). Here, search space group #0 can be understood as the default search space group.

[0102] The specific handover process will not be detailed here. Unlike the R16 search space group handover process, the explicit R17 search space group handover is triggered by scheduling a specific DCI format of the PDSCH (Physical Downlink Shared Channel) or PUSCH (Physical Uplink Shared Channel), rather than by explicitly instructing the search space group handover based on DCI format 2-0 as in the R16 search space group handover. This specific DCI format can include: DCI format 0_1, and / or DCIformat1_1, and / or DCI format 0_2, and / or DCI format 1_2.

[0103] The R17 search space group switching indication is used to instruct the terminal to switch to the target search space group. The terminal performs the corresponding PDCCH listening based on the PDCCH listening behavior corresponding to the target search space group.

[0104] Another difference is that the R17 search space group switching scheme does not have an implicit switching process. That is, it does not have a triggering mechanism like the R16 implicit one (that is, the terminal will trigger a switch from group0 to group1 when it detects any DCI format on group0). The switching can only be triggered by explicitly indicating the above-mentioned DCI format 0-1, 1-1, 1-2 and / or 0-2, or by triggering the switching when the second timer expires.

[0105] 2. R17 PDCCH skipping;

[0106] PDCCH skipping is a method of energy saving that uses the PDCCH skipping indication in the DCI to skip PDCCH listening for a certain period of time. For example, the PDCCH skipping DCI can be used to indicate skipping PDCCH listening in the next 4, 8, and 16 time slots. Skipping PDCCH listening means not listening to PDCCH. However, it should be noted that the PDCCH skipping period mentioned here refers to the first type of PDCCH, that is, the PDCCH corresponding to Type 3-PDCCH CSS sets or USS sets. In other words, only the PDCCH corresponding to Type 3-PDCCH CSS sets or USS sets can be skipped.

[0107] During the period of skipping PDCCH listening, the corresponding PDCCH listening behavior of the terminal is: not to perform PDCCH listening, or to skip PDCCH listening.

[0108] There are two types of terminal behaviors corresponding to the PDCCH skipping indication bits. One type is all zero bits, in which the terminal does not skip PDCCH listening. The other type is non-all zero bits, in which the terminal skips PDCCH listening within a specific time interval (i.e., the PDCCH corresponding to Type3-PDCCH CSS sets or USS sets).

[0109] III. Regarding Channel Occupancy Time (COT): Before transmitting information in unlicensed frequency bands, 5G communication systems, on unlicensed frequency bands of the New Radio (NR) interface, require terminals or network devices to perform Clear Channel Assessment (CCA) or Extended Clear Channel Assessment (eCCA) to listen to the channel, i.e., to perform Energy Detection (ED). When the energy is below a certain threshold, the channel is determined to be empty, and transmission can begin, i.e., LBT (listen before talk). COT is the channel occupancy time obtained after a successful LBT.

[0110] The channel monitoring method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios. Furthermore, the channel referred to below may specifically refer to the aforementioned "first type of PDCCH" or other specific types of PDCCH, which will not be elaborated further below.

[0111] The channel monitoring method provided in the embodiments of this application, such as Figure 2 As shown, it includes:

[0112] Step 21: The terminal acquires at least two types of channel monitoring information;

[0113] Step 22: The terminal performs operations related to monitoring the Physical Downlink Control Channel (PDCCH) based on at least two types of channel monitoring information.

[0114] The at least two types of channel monitoring information include at least two of the following: PDCCH skip information; Channel Occupancy Time (COT) information; First type of search space group switching information; The first type of search space group switching information includes at least one of the following: First type of search space group switching indication information, status information of the first type of search space group switching timer, and configuration information related to the first type of search space group switching; Second type of search space group switching information; The second type of search space group switching information includes at least one of the following: Second type of search space group switching indication information, status information of the second type of search space group switching timer, and configuration information related to the second type of search space group switching; Status change information of a partial bandwidth inactive timer; Status change information of discontinuous reception DRX related timers.

[0115] Correspondingly, step 21 may specifically include: the terminal acquiring at least two of the following: PDCCH skipping information, channel occupancy time (COT) information, first type search space group switching information, second type search space group switching information, status change information of partial bandwidth inactive timers, and status change information of discontinuous reception DRX related timers.

[0116] Furthermore, it should be noted that the at least two types of channel monitoring information acquired by the terminal can be acquired simultaneously or separately. For example, if the "at least two types of channel monitoring information" are PDCCH skip information and COT information, the terminal can acquire the PDCCH skip information and COT information simultaneously, or it can acquire the PDCCH skip information and COT information separately, such as acquiring the PDCCH skip information first and then acquiring the COT information; however, this is not a limitation.

[0117] It is worth noting that step 21 does not limit the number of times various channel monitoring information is acquired. For example, when at least two types of channel monitoring information include PDCCH skip information and Channel Occupancy Time (COT) information, the terminal may receive PDCCH skip information once or multiple times within the COT period after acquiring the COT information. This embodiment only uses PDCCH skip information and COT information as examples, and the number of times other types of channel monitoring information are acquired is not limited.

[0118] The “PDCCH skip information” may include at least one of the following: PDCCH skip instruction information and PDCCH skip related configuration information; the “status information” may include: status change information; the default search space group may be obtained based on at least one of the following: “first type of search space group switching related configuration information” or “second type of search space group switching related configuration information”.

[0119] The channel monitoring method provided in this application embodiment obtains at least two types of channel monitoring information through the terminal; and performs operations related to monitoring the Physical Downlink Control Channel (PDCCH) based on the at least two types of channel monitoring information; it can support channel monitoring for multiple types of channel monitoring information, clarify the UE's related behavior for PDCCH monitoring, and improve communication performance; and effectively solves the problem in the prior art that the terminal cannot determine the monitoring behavior for multiple channel monitoring schemes.

[0120] In this embodiment of the application, the search spaces associated with the first search space group and the second search space group may be the same or different; wherein, the first search space group and the second search space group have the same identifier, the first search space group is the search space group associated with the first type of search space group switching information, and the second search space group is the search space group associated with the second type of search space group switching information.

[0121] This allows for more flexible implementation of the solution.

[0122] The following description addresses the cases where the at least two types of channel monitoring information contain different information.

[0123] Optionally, when the at least two types of channel monitoring information include the PDCCH skipping information and the second type of search space group switching information,

[0124] The PDCCH skip information is not applied during the activation of search space group #0 in the second type of search space group; and / or,

[0125] The PDCCH skip information is applied during the activation of search space group #1 in the second type of search space group.

[0126] For example, the first type of search space group is the R17 version protocol (R17) search space group, and the second type of search space group is the R16 version protocol (R16) search space group. The terminal does not apply the PDCCH skip information during the activation of R16 search space group #0 (that is, during the application of R16 search space group #0).

[0127] It is understood that the terminal not applying the PDCCH skip information during the activation of R16 search space group #0 means that during the activation of R16 search space group #0, the terminal either 1) does not perform PDCCH listening skip, or 2) does not apply the PDCCH skip indication information.

[0128] Optionally, when the at least two types of channel monitoring information include the first type of search space group switching information and the second type of search space group switching information,

[0129] The first type of search space group switching information is not applied during the activation of search space group #0 in the second type of search space group; and / or,

[0130] The first type of search space group switching information is applied during the activation of search space group #1 in the second type of search space group.

[0131] For example, the second type of search space group is the Version 16 (R16) search space group. The terminal does not apply the first type of search space group switching information during the activation of R16 search space group #0 (i.e., during the application of R16 search space group #0).

[0132] It is understandable that the terminal does not apply the first type of search space group switching information during the activation of search space group #0 in R16, meaning that the terminal will not activate or apply the first type of search space group during the activation of search space group #0 in R16.

[0133] In another embodiment,

[0134] Optionally, when the at least two types of channel monitoring information include the PDCCH skipping information and the second type of search space group switching information,

[0135] The PDCCH skip information is not applied during the activation of search space group #1 in the second type of search space group; and / or,

[0136] The PDCCH skip information is applied during the activation of search space group #0 in the second type of search space group.

[0137] Optionally, when the at least two types of channel monitoring information include the first type of search space group switching information and the second type of search space group switching information,

[0138] The first type of search space group switching information is not applied during the activation of search space group #1 in the second type of search space group; and / or,

[0139] The first type of search space group switching information is applied during the activation of search space group #0 in the second type of search space group.

[0140] Optionally, when the at least two types of channel monitoring information include the first type of search space group switching information and the second type of search space group switching information, the terminal pauses or stops running the first type of search space group switching timer during the activation of search space group #0 in the second type of search space group; wherein, the first type of search space group switching information includes: the status information of the first type of search space group switching timer.

[0141] For example, during the activation of search space group #0 in R16, the terminal pauses or stops running the R17 search space group switching timer. Further, during the exit from the activation of search space group #0 in R16 (i.e., switching to search space group #1 in R16), the R17 search space group switching timer resumes or starts running.

[0142] Optionally, when the at least two types of channel monitoring information include: first type search space group switching information and second type search space group switching information, the terminal performs operations related to PDCCH monitoring based on the at least two types of channel monitoring information, including:

[0143] The terminal listens to the PDCCH in the third search space, wherein the third search space is the search space associated with the search space group activated in the first type of search space group and / or the search space group activated in the second type of search space group.

[0144] This can be understood as the terminal listening to the PDCCH in the search space of the intersection or union of the two active search space groups, which are associated with the active R17 search space group and the active R16 search space group.

[0145] For example, the active R17 search space group is R17 search space group #2, and its associated search spaces are search spaces #1, #3, and #5; the active R16 search space group is R16 search space group #1, and its associated search spaces are search spaces #1, #2, and #4. In one embodiment, during the activation of these two search space groups, the terminal listens for the PDCCH only on search space #1. In another embodiment, during the activation of these two search space groups, the terminal listens for the PDCCH on search spaces #1, #2, #3, #4, and #5.

[0146] In the first scenario, when the at least two types of channel monitoring information include the PDCCH skipping information and the COT information, the PDCCH skipping information satisfies at least one of the following: it does not support the application of the PDCCH skipping information outside the COT (which can also be understood as the PDCCH skipping information not being able to be applied outside the COT); it supports the application of the PDCCH skipping information both inside and outside the COT (which can also be understood as the PDCCH skipping information being able to be applied both inside and outside the COT); and, if a first condition is met, it supports the application of the PDCCH skipping information outside the COT, wherein the first condition is related to at least one of the following: the length of the skipped PDCCH monitoring duration and the network-side device configuration information; wherein the skipped PDCCH monitoring duration is obtained based on the PDCCH skipping information.

[0147] It is understood that, in the embodiments of this application, it is also possible that, if the first condition is not met, the application of the PDCCH skipping information outside of COT is not supported.

[0148] The PDCCH skipping information applied within the COT and the PDCCH skipping information applied outside the COT satisfy at least one of the following: the corresponding configured skipped PDCCH listening durations are different; the supported skipped PDCCH types are different.

[0149] The PDCCH skipping information may include: PDCCH skipping indication information, network-side device configuration of skipped PDCCH listening duration information, and application scenario information of the PDCCH skipping indication information configured by the network side or agreed upon by the protocol.

[0150] In this embodiment of the application, during the PDCCH skipping period, the application priority of PDCCH skipping information can be higher than the application priority of the first type of search space group switching information and / or the second type of search space group switching information.

[0151] The second scenario involves the terminal performing an operation related to PDCCH monitoring based on the at least two types of channel monitoring information, including the PDCCH skipping information and the search space group switching information. This operation includes at least one of the following: (1) If the terminal obtains the search space group switching information during the skipped PDCCH monitoring duration, the terminal switches to the target search space group based on the search space group switching information, and performs PDCCH monitoring on the target search space group at or after the end of the skipped PDCCH monitoring duration; (2) If the terminal obtains the search space group switching information during the skipped PDCCH monitoring duration, the terminal performs an operation related to PDCCH monitoring at or after the end of the skipped PDCCH monitoring duration based on the PDCCH skipping information and the search space group switching information. (3) During the skipped PDCCH listening duration, the terminal pauses the search space group switching timer and resumes the operation of the search space group switching timer when or after the skipped PDCCH listening duration ends; (4) During the skipped PDCCH listening duration, if the terminal obtains the search space group switching information, the terminal switches to the target search space group according to the search space group switching information and performs PDCCH listening on the target search space group; wherein, the search space group switching information includes at least one of the first type of search space group switching information and the second type of search space group switching information, and the skipped PDCCH listening duration is obtained according to the PDCCH skip information.

[0152] Regarding item (1), "the terminal switches to the target search space group according to the search space group switching information, and performs PDCCH listening on the target search space group when or after the end of the skipped PDCCH listening duration", it can be specifically understood as: the terminal switches to the target search space group according to the search space group switching information but does not perform the corresponding PDCCH listening behavior, but waits until the end of the skipped PDCCH listening duration to perform the corresponding PDCCH listening behavior.

[0153] The phrase "perform PDCCH listening on the target search space group" can be understood as: performing PDCCH listening behavior corresponding to the target search space group. For details, please refer to the PDCCH listening behavior corresponding to the different space groups mentioned above. This same understanding applies to other parts of this case, and will not be elaborated further.

[0154] Regarding item (2), “Switch to the target search space group according to the search space group switching information” can be specifically understood as: switch to the target search space group according to the search space group switching information and perform the corresponding PDCCH listening behavior.

[0155] Under item (4), it may also include: the terminal stops executing skip PDCCH listening.

[0156] The third type, where the at least two types of channel monitoring information include the first type of search space group switching information and the COT information, the first type of search space group switching information satisfies one of the following: (1) it does not support the application of the first type of search space group switching information outside the COT (which can also be understood as the first type of search space group switching information cannot be applied outside the COT); (2) it supports the application of the first type of search space group switching information inside and outside the COT (which can also be understood as the first type of search space group switching information can be applied inside and outside the COT); (3) when the second condition is met, it supports the application of the first type of search space group switching information outside the COT, wherein the second condition is related to at least one of the search space group associated with the first type of search space group switching information and the network-side device configuration information.

[0157] It is understood that, in the embodiments of this application, specifically, the application of the first type of search space group switching information outside of COT is not supported if the second condition is not met.

[0158] Fourth, when the at least two types of channel monitoring information include the first type of search space group switching information and the second type of search space group switching information, the first type of search space group switching information and the second type of search space group switching information satisfy at least one of the following: (1) the first type of search space group switching information and the second type of search space group switching information cannot be used at the same time; (2) the first type of search space group switching information and the second type of search space group switching information can be used at the same time.

[0159] Correspondingly, the terminal performs operations related to PDCCH monitoring based on at least two types of channel monitoring information, including: when the terminal obtains the first type of search space group switching information and the second type of search space group switching information in the same time unit, simultaneously applying the first type of search space group switching information and the second type of search space group switching information, or applying any one of the first type of search space group switching information and the second type of search space group switching information.

[0160] The time unit can be a time slot or other time unit, and there is no limitation here.

[0161] Wherein, the first type of search space group switching information and the second type of search space group switching information cannot be applied simultaneously, including: the terminal applies the target search space group switching information obtained at the current moment, and stops applying search space group switching information of a different type than the target search space group switching information obtained before the current moment; wherein, the target search space group switching information is either the first type of search space group switching information or the second type of search space group switching information.

[0162] In addition, when the first type of search space group switching information and the second type of search space group switching information can be applied simultaneously, the terminal performs operations related to PDCCH monitoring based on the at least two types of channel monitoring information, including at least one of the following: (1) when the terminal determines to monitor the first target search space based on at least one of the first type of search space group switching information and the second type of search space group switching information, monitors the PDCCH on the first target search space; (2) when the terminal determines not to monitor the second target search space based on at least one of the first type of search space group switching information and the second type of search space group switching information, does not monitor the PDCCH on the second target search space.

[0163] It should be noted that when the terminal determines to monitor the search space based on at least one of the first type of search space group switching information and the second type of search space group switching information, the method for monitoring the PDCCH on the search space can be that the terminal determines the current search space group of each application based on the first type of search space group switching information and the second type of search space group switching information, thereby obtaining the search spaces associated with the search space groups of each application, and then the terminal can determine the search space to monitor.

[0164] In one embodiment, the network configuration is such that the terminal only needs to monitor the PDCCH on the first target search space when it determines, based on the first type of search space group switching information and the second type of search space group switching information, that it needs to monitor the first target search space. For example, the terminal determines, based on the first type of search space group switching information and the second type of search space group switching information, that its current application's search space group is search space group #1 and search space group #0, respectively. The search spaces associated with these two search space groups are: search space group #1 is associated with search spaces #4, #5, and #6, and search space group #0 is associated with search spaces #5, #6, and #7. Therefore, the terminal can determine that the search spaces to monitor are search spaces #4 and #5.

[0165] Fifthly, when the at least two types of channel monitoring information include the PDCCH skipping information and the state change information of the partial bandwidth inactive timer, the terminal performs operations related to PDCCH monitoring based on the at least two types of channel monitoring information, including at least one of the following: (1) when the partial bandwidth inactive timer expires during the skipped PDCCH monitoring duration, the terminal clears the remaining skipped PDCCH monitoring duration and / or switches to the default search space group; (2) when the partial bandwidth inactive timer starts or restarts during the skipped PDCCH monitoring duration, the terminal continues to run the skipped PDCCH monitoring duration; wherein the skipped PDCCH monitoring duration is obtained based on the PDCCH skipping information; and the default search space group is obtained based on the first type of search space group switching information or the second type of search space group switching information.

[0166] One interpretation of "the terminal clears the remaining skipped PDCCH listening duration" is: the terminal clears the remaining skipped PDCCH listening duration and resumes PDCCH listening. Another interpretation is: the terminal clears the remaining skipped PDCCH listening duration and stops the skipped PDCCH listening behavior corresponding to the skipped PDCCH duration.

[0167] Regarding "the terminal continues to run the skip PDCCH listening duration", it can be specifically understood as: the terminal continues to execute skip PDCCH listening.

[0168] The sixth method involves the terminal performing an operation related to PDCCH monitoring based on the at least two types of channel monitoring information, including the first type of search space group switching information and the state change information of the partial bandwidth inactive timer. This operation includes at least one of the following: (1) performing a first operation when the partial bandwidth inactive timer expires; (2) continuing to apply the current search space group when the partial bandwidth inactive timer is started or restarted. The first operation includes at least one of the following: switching to the default search space group; restarting the first type of search space group switching timer; continuing to apply the current search space group; and continuing to run the first type of search space group switching timer. The current search space group and the default search space group are obtained based on the first type of search space group switching information.

[0169] Regarding item (1), the execution of the first operation includes performing the listening behavior of its corresponding PDCCH.

[0170] Regarding the "default search space group" involved, it can be specified by the network-side device configuration, such as search space group #0; this interpretation can apply to any one or more of the first type above to the eighth type below.

[0171] The statement that "the default search space group is obtained based on the switching information of the first type of search space group" can also be understood as: the network-side device configures a default search space group for the first type of search space group.

[0172] The seventh method involves the terminal performing an operation related to PDCCH monitoring based on the at least two types of channel monitoring information, including the PDCCH skipping information and the state change information of the DRX-related timer. This operation includes at least one of the following: (1) if the DRX-related timer expires during the skipped PDCCH monitoring duration, the terminal continues to run the skipped PDCCH monitoring duration; (2) if the DRX-related timer starts or restarts during the skipped PDCCH monitoring duration, the terminal continues to run the skipped PDCCH monitoring duration, or the terminal clears the remaining skipped PDCCH monitoring duration; wherein the skipped PDCCH monitoring duration is obtained based on the PDCCH skipping information.

[0173] Regarding "the terminal continues to run the skip PDCCH listening duration", it can be specifically understood as: continuing to apply the behavior corresponding to the skip PDCCH listening duration, that is, skipping PDCCH listening;

[0174] One interpretation of "the terminal clears the remaining skipped PDCCH listening duration" is: the terminal clears the remaining skipped PDCCH listening duration and resumes PDCCH listening. Another interpretation is: the terminal clears the remaining skipped PDCCH listening duration and stops the skipped PDCCH listening behavior corresponding to the skipped PDCCH duration.

[0175] Eighth, when the at least two types of channel monitoring information include the first type of search space group switching information and the state change information of the DRX-related timer, the terminal performs an operation related to PDCCH monitoring based on the at least two types of channel monitoring information, including at least one of the following: (1) when the DRX-related timer is started or restarted, continue to apply the current search space group or switch to the default search space group; (2) when the DRX-related timer expires, continue to apply the current search space group or switch to the default search space group; wherein the current search space group and the default search space group are obtained based on the first type of search space group switching information.

[0176] In this embodiment of the application, the terminal performs operations related to PDCCH monitoring based on the at least two types of channel monitoring information, including: the terminal adopts a first method to perform operations related to PDCCH monitoring based on the at least two types of channel monitoring information; wherein, the first method includes at least one of the following: a network configuration indication method; a scheduled indication method; and a pre-configuration indication method.

[0177] This allows for flexible implementation of the proposed solution.

[0178] This application also provides a channel monitoring method, such as... Figure 3 As shown, it includes:

[0179] Step 31: The network-side device configuration terminal performs operations related to monitoring the Physical Downlink Control Channel (PDCCH) based on at least two types of channel monitoring information.

[0183] The channel monitoring method provided in this application configures the terminal to perform operations related to monitoring the Physical Downlink Control Channel (PDCCH) based on at least two types of channel monitoring information through the network-side device; it can support channel monitoring for multiple types of channel monitoring information, clarify the UE's related behavior for PDCCH monitoring, and improve communication performance; it effectively solves the problem in the prior art that the terminal cannot determine the monitoring behavior for multiple channel monitoring schemes.

[0184] In this embodiment, the network-side device configures the search spaces associated with the first search space group and the second search space group to be the same or different; wherein, the first search space group and the second search space group have the same identifier, the first search space group is the search space group associated with the first type of search space group switching information, and the second search space group is the search space group associated with the second type of search space group switching information. This allows for more flexible implementation of the solution.

[0185] Optionally, when the at least two types of channel monitoring information include the PDCCH skipping information and the second type of search space group switching information, the PDCCH skipping information and the second type of search space group switching information satisfy at least one of the following:

[0186] The PDCCH skip information is not applied during the activation of search space group #0 in the second type of search space group;

[0190] The first type of search space group switching information is applied during the activation of search space group #1 in the second type of search space group.

[0191] The following description addresses the cases where the at least two types of channel monitoring information contain different information.

[0192] In the first scenario, when the at least two types of channel monitoring information include the PDCCH skipping information and the COT information, the network-side device configures the PDCCH skipping information to satisfy at least one of the following: it does not support the application of the PDCCH skipping information outside the COT (which can also be understood as the PDCCH skipping information not being applicable outside the COT); it supports the application of the PDCCH skipping information both inside and outside the COT (which can also be understood as the PDCCH skipping information being applicable both inside and outside the COT); and, if a first condition is satisfied, it supports the application of the PDCCH skipping information outside the COT, wherein the first condition is related to at least one of the following: the length of the skipped PDCCH monitoring duration and the network-side device configuration information; wherein the skipped PDCCH monitoring duration is obtained based on the PDCCH skipping information.

[0193] It is understood that, in the embodiments of this application, it is also possible that, if the first condition is not met, the application of the PDCCH skipping information outside of COT is not supported.

[0194] The PDCCH skipping information applied within the COT and the PDCCH skipping information applied outside the COT satisfy at least one of the following: the duration of the skipped PDCCH listening configured by the network-side device is different; and the types of PDCCH that are supported for skipping are different.

[0195] The PDCCH skipping information may include: PDCCH skipping indication information, network-side device configuration of skipped PDCCH listening duration information, and application scenario information of the PDCCH skipping indication information configured by the network side or agreed upon by the protocol.

[0196] In this embodiment of the application, during the PDCCH skipping period, the application priority of PDCCH skipping information can be higher than the application priority of the first type of search space group switching information and / or the second type of search space group switching information.

[0197] The second scenario involves the network-side device configuring the terminal to perform PDCCH monitoring-related operations based on the at least two types of channel monitoring information, including configuring the network-side device to perform at least one of the following operations: (1) If the terminal obtains the search space group switching information during the skipped PDCCH monitoring duration, the terminal switches to the target search space group based on the search space group switching information, and performs PDCCH monitoring on the target search space group at or after the end of the skipped PDCCH monitoring duration; (2) If the terminal obtains the search space group switching information during the skipped PDCCH monitoring duration, the terminal performs PDCCH monitoring on the target search space group at or after the end of the skipped PDCCH monitoring duration. Then, the terminal switches to the target search space group according to the search space group switching information; (3) During the skipped PDCCH listening duration, the terminal pauses the search space group switching timer and resumes the operation of the search space group switching timer when or after the skipped PDCCH listening duration ends; (4) If the terminal obtains the search space group switching information during the skipped PDCCH listening duration, the terminal switches to the target search space group according to the search space group switching information and performs PDCCH listening on the target search space group; wherein, the search space group switching information includes at least one of the first type of search space group switching information and the second type of search space group switching information, and the skipped PDCCH listening duration is obtained according to the PDCCH skip information.

[0198] Regarding item (1), "the terminal switches to the target search space group according to the search space group switching information, and performs PDCCH listening on the target search space group when or after the end of the skipped PDCCH listening duration", it can be specifically understood as: the terminal switches to the target search space group according to the search space group switching information but does not perform the corresponding PDCCH listening behavior, but waits until the end of the skipped PDCCH listening duration to perform the corresponding PDCCH listening behavior.

[0199] The phrase "perform PDCCH listening on the target search space group" can be understood as: performing PDCCH listening behavior corresponding to the target search space group. For details, please refer to the PDCCH listening behavior corresponding to the different space groups mentioned above. This same understanding applies to other parts of this case, and will not be elaborated further.

[0200] Regarding item (2), “Switch to the target search space group according to the search space group switching information” can be specifically understood as: switch to the target search space group according to the search space group switching information and perform the corresponding PDCCH listening behavior.

[0201] Under item (4), it may also include: the terminal stops executing skip PDCCH listening.

[0203] It is understood that, in the embodiments of this application, specifically, the application of the first type of search space group switching information outside of COT is not supported if the second condition is not met.

[0204] Fourth, when the at least two types of channel monitoring information include the first type of search space group switching information and the second type of search space group switching information, the network-side device configures the first type of search space group switching information and the second type of search space group switching information to satisfy at least one of the following: (1) the first type of search space group switching information and the second type of search space group switching information cannot be applied at the same time; (2) the first type of search space group switching information and the second type of search space group switching information can be applied at the same time.

[0205] Correspondingly, the network-side device configures the terminal to perform operations related to PDCCH monitoring based on at least two types of channel monitoring information, including: the network-side device configures the terminal to simultaneously apply the first type of search space group switching information and the second type of search space group switching information, or apply any one of the first type of search space group switching information and the second type of search space group switching information, when the terminal obtains the first type of search space group switching information and the second type of search space group switching information in the same time unit.

[0206] The time unit can be a time slot or other time unit, and there is no limitation here.

[0207] Wherein, the first type of search space group switching information and the second type of search space group switching information cannot be applied simultaneously, including: the terminal applies the target search space group switching information obtained at the current moment, and stops applying search space group switching information of a different type than the target search space group switching information obtained before the current moment; wherein, the target search space group switching information is either the first type of search space group switching information or the second type of search space group switching information.

[0208] In addition, when the first type of search space group switching information and the second type of search space group switching information can be applied simultaneously, the network-side device configures the terminal to perform operations related to PDCCH monitoring based on at least two types of channel monitoring information, including configuring the network-side device to configure at least one of the following: (1) when the terminal determines to monitor the first target search space based on at least one of the first type of search space group switching information and the second type of search space group switching information, the terminal monitors the PDCCH on the first target search space; (2) when the terminal determines not to monitor the second target search space based on at least one of the first type of search space group switching information and the second type of search space group switching information, the terminal does not monitor the PDCCH on the second target search space.

[0209] It should be noted that when the terminal determines to monitor the search space based on at least one of the first type of search space group switching information and the second type of search space group switching information, the method for monitoring the PDCCH on the search space can be that the terminal determines the current search space group of each application based on the first type of search space group switching information and the second type of search space group switching information, thereby obtaining the search spaces associated with the search space groups of each application, and then the terminal can determine the search space to monitor.

[0210] In one embodiment, the network configuration is such that the terminal only needs to monitor the PDCCH on the first target search space when it determines, based on the first type of search space group switching information and the second type of search space group switching information, that it needs to monitor the first target search space. For example, the terminal determines, based on the first type of search space group switching information and the second type of search space group switching information, that its current application's search space group is search space group #1 and search space group #0, respectively. The search spaces associated with these two search space groups are: search space group #1 is associated with search spaces #4, #5, and #6, and search space group #0 is associated with search spaces #5, #6, and #7. Therefore, the terminal can determine that the search spaces to monitor are search spaces #4 and #5.

[0211] Fifthly, when the at least two types of channel monitoring information include the PDCCH skipping information and the state change information of the partial bandwidth inactive timer, the network-side device configures the terminal to perform operations related to PDCCH monitoring based on the at least two types of channel monitoring information, including configuring the network-side device to configure at least one of the following: (1) when the partial bandwidth inactive timer expires during the skipped PDCCH monitoring duration, the terminal clears the remaining skipped PDCCH monitoring duration and / or switches to the default search space group; (2) when the partial bandwidth inactive timer starts or restarts during the skipped PDCCH monitoring duration, the terminal continues to run the skipped PDCCH monitoring duration; wherein the skipped PDCCH monitoring duration is obtained based on the PDCCH skipping information; and the default search space group is obtained based on the first type of search space group switching information or the second type of search space group switching information.

[0212] One interpretation of "the terminal clears the remaining skipped PDCCH listening duration" is: the terminal clears the remaining skipped PDCCH listening duration and resumes PDCCH listening. Another interpretation is: the terminal clears the remaining skipped PDCCH listening duration and stops the skipped PDCCH listening behavior corresponding to the skipped PDCCH duration.

[0213] Regarding "the terminal continues to run the skip PDCCH listening duration", it can be specifically understood as: the terminal continues to execute skip PDCCH listening.

[0214] The sixth method involves the network-side device configuring the terminal to perform PDCCH monitoring-related operations based on the at least two types of channel monitoring information, including the first type of search space group switching information and the state change information of the partial bandwidth inactive timer. This includes configuring the network-side device to perform at least one of the following: (1) when the partial bandwidth inactive timer expires, the terminal performs a first operation; (2) when the partial bandwidth inactive timer starts or restarts, the terminal continues to apply the current search space group. The first operation includes at least one of the following: switching to the default search space group; restarting the first type of search space group switching timer; continuing to apply the current search space group; continuing to run the first type of search space group switching timer.

[0216] Regarding the "default search space group" involved, it can be specified by the network-side device configuration, such as search space group #0; this interpretation can apply to any one or more of the first type above to the eighth type below.

[0217] The statement that "the default search space group is obtained based on the switching information of the first type of search space group" can also be understood as: the network-side device configures a default search space group for the first type of search space group.

[0218] The seventh scenario involves the network-side device configuring the terminal to perform PDCCH monitoring-related operations based on the at least two types of channel monitoring information, including configuring at least one of the following: (1) if the DRX-related timer expires during the skipped PDCCH monitoring duration, the terminal continues to run the skipped PDCCH monitoring duration; (2) if the DRX-related timer starts or restarts during the skipped PDCCH monitoring duration, the terminal continues to run the skipped PDCCH monitoring duration, or the terminal clears the remaining skipped PDCCH monitoring duration; wherein the skipped PDCCH monitoring duration is obtained based on the PDCCH skip information.

[0219] Regarding "the terminal continues to run the skip PDCCH listening duration", it can be specifically understood as: continuing to apply the behavior corresponding to the skip PDCCH listening duration, that is, skipping PDCCH listening;

[0220] One interpretation of "the terminal clears the remaining skipped PDCCH listening duration" is: the terminal clears the remaining skipped PDCCH listening duration and resumes PDCCH listening. Another interpretation is: the terminal clears the remaining skipped PDCCH listening duration and stops the skipped PDCCH listening behavior corresponding to the skipped PDCCH duration.

[0221] Eighth, when the at least two types of channel monitoring information include the first type of search space group switching information and the state change information of the DRX-related timer, the network-side device configures the terminal to perform operations related to PDCCH monitoring based on the at least two types of channel monitoring information, including configuring the network-side device to configure at least one of the following: (1) when the DRX-related timer is started or restarted, the terminal continues to apply the current search space group or switches to the default search space group; (2) when the DRX-related timer expires, the terminal continues to apply the current search space group or switches to the default search space group; wherein the current search space group and the default search space group are obtained based on the first type of search space group switching information.

The PDCCH skipping information is exemplified by the R17 PDCCH skipping indication information, corresponding to R17 PDCCH skipping; the first type of search space group switching information is exemplified by the R17 SSSG switching information, corresponding to R17 SSSG switching; the second type of search space group switching information is exemplified by the R16 SSSG switching information, corresponding to R16 SSSG switching; and the first method is exemplified by the network configuration indication method. The monitoring behavior of "performing PDCCH monitoring on the XX search space group" mentioned below is consistent with the monitoring behavior of the XX search space group described above, that is, performing PDCCH monitoring on the XX search space group and stopping PDCCH monitoring on other search space groups. For example, the PDCCH monitoring behavior of the terminal corresponding to search space group #0 is: only monitoring PDCCH on search space group #0, and stopping PDCCH monitoring on search space groups other than search space group #0; this will not be elaborated further below.

[0223] To address the aforementioned technical problems, this application provides a channel monitoring method, specifically a PDCCH monitoring adaptation method. This method combines the R16 SSSG handover scheme with the R17 PDCCH monitoring adaptation scheme, clearly identifies the UE's related behaviors regarding PDCCH monitoring, and improves communication performance. Specifically, the solution provided in this application includes the following parts:

[0224] Furthermore, the following description breaks down the R17 PDCCH monitoring adaptation scheme into two sub-schemes: R17SSSG switching and R17 PDCCH skipping. In practical applications, these can be combined or split as needed, and no restrictions are imposed here.

[0225] Part 1: R17 PDCCH skipping combined with (R16 SSSG handover or R17 SSSG handover) scheme (involving cases where at least two types of channel monitoring information include the PDCCH skipping information and the COT information, and cases where at least two types of channel monitoring information include the PDCCH skipping information and the search space group handover information). The following description uses R16 SSSG handover as an example; the same applies to R17 SSSG handover (but the combination with R17 SSSG handover does not involve COT-related content, only the terminal behavior part). It should be noted that the combination scheme of R17 PDCCH skipping and R17 SSSG handover can select different terminal behaviors than the combination scheme of R17 PDCCH skipping and R16 SSSG handover, and this is not limited here.

[0226] 1. This section includes at least one of the following:

[0227] 1) Method 1: R17 PDCCH skipping cannot be applied outside of COT. Understandably, the skipping duration (the duration of skipping PDCCH listening) indicated by the R17 PDCCH skipping instruction will be interrupted or stopped when outside of COT.

[0228] Furthermore: The R17 PDCCH skipping method in Method 1 can also be applied within the COT, and is not limited here.

[0229] 2) Method 2: The R17 PDCCH skipping scheme can be applied both inside and outside the COT. It is understood that the skipping duration indicated by the R17 PDCCH skipping instruction will not be interrupted or stopped outside the COT, such as... Figure 4 As shown;

[0230] 3) Method 3: Further, Method 1 or Method 2 described above in this section can be selected to be applied based on specific conditions (corresponding to the first condition above).

[0231] Preferably, the specific condition includes: the length of the skipping duration (corresponding to the length of the skipped PDCCH listening duration described above). For example, when the skipping duration length is less than the first time length, method 1 is applied, and / or when the skipping duration length is greater than or equal to the first time length, method 2 is applied.

[0232] 2. The network side configuration applies one of the above methods. For example, the network side configuration applies one of method 1, method 2, and method 3.

[0233] 3. Terminal behavior:

[0234] (1) The UE PDCCH listening behavior corresponding to the R17 PDCCH skipping scheme applied within and outside the COT can be different. The PDCCH skipping information applied within the COT and the PDCCH skipping information applied outside the COT shall satisfy at least one of the following: the corresponding configured skipped PDCCH listening duration is different; the supported skipped PDCCH types are different.

[0235] 1) Specifically, "different" can refer to the different types of PDCCHs skipped within the skipping duration indicated by PDCCH skipping. For example, the types of PDCCHs that can be skipped within COT include PDCCHs corresponding to a specific type search space, or PDCCHs corresponding to a specific DCI format, or PDCCHs corresponding to DCIs scrambled with a specific RNTI (Radio Network Temporary Identifier), etc.; no further limitation is made here.

[0236] (2) During the PDCCH skipping duration, the application priority of the terminal behavior of skipping PDCCH listening can be higher than the application priority of R16 SSSG handover information. That is to say, during the PDCCH skipping duration, the terminal always follows the behavior of skipping PDCCH listening and will not be affected by R16 SSSG handover information.

[0237] For example, if an R16 SSSG handover instruction is received within the skipping duration, or if the R16 search space group handover timer expires, then... Figure 5 As shown, the terminal executes any of the following options:

[0238] 1) Option 1: Switch to the target search space group according to the switching instruction or the timer expiration, but still follow the behavior of skipping PDCCH monitoring until the skipping duration ends, and then perform the corresponding PDCCH monitoring behavior on the target search space group. Corresponding to the above situation where the terminal obtains the search space group switching information during the skipped PDCCH monitoring duration, the terminal switches to the target search space group according to the search space group switching information, and performs PDCCH monitoring on the target search space group when or after the skipped PDCCH monitoring duration ends.

[0239] 2) Option 2: Instead of switching to the target search space group based on the switching instruction or the expiration of the timer, the terminal switches to the target search space group and performs corresponding PDCCH monitoring on the target search space group only after the skipping duration ends. Corresponding to the situation described above where the terminal obtains the search space group switching information during the skipped PDCCH monitoring period, the terminal switches to the target search space group based on the search space group switching information at or after the end of the skipped PDCCH monitoring period.

[0240] (3) During the PDCCH skipping duration, the R16 SSSG switching timer is paused, and the timer resumes operation after the skipping duration ends. Corresponding to the above, during the skipped PDCCH listening duration, the terminal pauses the search space group switching timer, and resumes operation of the search space group switching timer when or after the skipped PDCCH listening duration ends.

[0241] (4) During the PDCCH skipping duration, if a handover instruction from R16 SSSG is received or if the R16 search space group handover timer expires, the terminal stops the PDCCH skipping duration, that is, stops the corresponding skipped PDCCH listening behavior, and switches to the target search space group to perform the corresponding PDCCH listening behavior. Corresponding to the above situation where, during the skipped PDCCH listening duration, the terminal obtains the search space group handover information, the terminal stops skipping PDCCH listening, and switches to the target search space group according to the search space group handover information to perform PDCCH listening on the target search space group.

[0242] (5) The network side can be configured to apply the above-mentioned terminal behavior if an R16 SSSG handover instruction is received or if the R16 search space group handover timer expires within the skipping duration.

[0243] Part Two: Combination Scheme of R17 SSSG Handover and R16 SSSG Handover (involving cases where at least two types of channel monitoring information include the first type of search space group handover information and the COT information, and cases where at least two types of channel monitoring information include the first type of search space group handover information and the second type of search space group handover information);

[0244] 1. This section includes at least one of the following:

[0245] 1) Restrict the application of the R17 SSSG handover scheme during the Channel Occupied Time (COT).

[0246] Furthermore: The R17 SSSG handover scheme cannot be applied outside of COT, such as... Figure 6 As shown.

[0247] 2) The R17 SSSG switching scheme can be applied both outside and inside the COT.

[0248] 2. Terminal behavior includes any of the following Options:

[0249] (1) Option 1: The R17 SSSG handover scheme and the R16 SSSG handover scheme cannot be used simultaneously;

[0250] 1) Only one of the R17 SSSG handover scheme and the R16 SSSG handover scheme can be applied at a time. This can also be understood as: the terminal applies either the R16 SSSG handover instruction or the R17 SSSG handover instruction according to the time sequence. This corresponds to the terminal applying the target search space group handover information obtained at the current moment and ceasing the application of search space group handover information of a different type obtained before the current moment.

[0251] 2) The handover instruction of R17 SSSG will overwrite (overwrite) the handover instruction of R16 SSSG, or the handover instruction of R16 SSSG will overwrite the handover instruction of R17 SSSG (which can also be understood as handover information).

[0252] Furthermore, if the terminal obtains both R16 SSSG handover information and R17 SSSG handover information within the same slot, it will apply one of them, or in the case of network configuration, the terminal will apply one of them.

[0253] For example, if a terminal receives an R17 SSSG handover instruction or a timer related to the R17 search space group undergoes a status change (e.g., timer expires, timer starts / restarts, timer pauses, timer resumes), while applying an R16 SSSG handover instruction, the terminal will cease its R16 SSSG handover monitoring and will follow the R17 SSSG handover instruction and / or monitor the corresponding PDCCH based on the R17 SSSG handover timer status. Specifically... Figure 7 The UE behavior is described.

[0254] (2) Option 2: The R17 SSSG handover scheme and the R16 SSSG handover scheme can be applied simultaneously, but the following new UE behavior is defined:

[0255] 1) For a search space, when the terminal is triggered to listen to the search space by R17 SSSG handover information and R16 SSSG handover information, the UE can perform PDCCH listening on that search space (that is, listen to the PDCCH corresponding to that search space). The same procedure applies to other search space groups to confirm whether to listen to the PDCCH corresponding to that search space group. Specifically, when the terminal determines to listen to the first target search space based on both the first type of search space group handover information and the second type of search space group handover information, it listens to the PDCCH on the first target search space.

[0256] For example, regarding the terminal-dedicated search space USS1, if the terminal receives an R16 SSSG handover instruction to apply PDCCH monitoring on the search space group associated with USS1, and if there is no associated USS1 on any of the search space groups currently active in the R17 SSSG handover mechanism, the terminal will not monitor PDCCH on USS1 until the R17 SSSG handover mechanism applies a search space group associated with USS1 and the R16 SSSG handover instruction to apply the search space group associated with USS1 is still active. Then, the terminal will begin monitoring PDCCH on USS1. See [link to relevant documentation]. Figure 8 As shown.

[0257] 2) For a search space, if the terminal is triggered to listen to that search space by the R17 SSSG handover mechanism or the R16 SSSG handover mechanism, the UE can listen to the PDCCH in that search space (that is, listen to the PDCCH corresponding to that search space). The same procedure applies to other search space groups to confirm whether to listen to the PDCCH corresponding to that search space group. Specifically, if the terminal determines to listen to the first target search space based on either the first type of search space group handover information or the second type of search space group handover information, it will listen to the PDCCH in the first target search space.

[0258] For example, regarding the terminal-dedicated search space USS1, when the terminal receives an R16 SSSG handover instruction to apply the search space group associated with USS1 for PDCCH listening, the terminal begins PDCCH listening on USS1, regardless of whether the current R17 SSSG handover mechanism applies the search space group associated with USS1. The same applies to the R17 SSSG handover mechanism; as long as the instruction is to apply the search space group associated with USS1, the terminal will perform PDCCH listening on USS1, regardless of which search space group the R16 SSSG handover mechanism applies. See [link to relevant documentation]. Figure 9 As shown.

[0259] (3) The network side can configure one or more of the above-mentioned UE behaviors (i.e., Options) to be used.

[0260] 3. The network can be configured to allow search space groups with the same search space group ID in both the R16 SSSG handover scheme and the R17 SSSG handover scheme to be associated with different search spaces, or to be restricted to being associated with the same search space. This corresponds to whether the search spaces associated with the first search space group and the second search space group are the same or different.

[0261] For example, consider the case where search spaces with the same ID in both schemes are associated with the same search space. Search space group 1 configured in the R16 SSSG handover scheme has the same ID as search space group 1 configured in the R17 SSSG handover scheme. If search space group 1 in the R16 SSSG handover scheme is associated with search spaces 5-7, then search space group 1 in the R17 SSSG handover scheme also needs to be associated with search spaces 5-7.

[0262] Part Three: Combining R17 PDCCH skipping with BWP timer (corresponding to the case where at least two types of channel monitoring information are mentioned above, including PDCCH skipping information and state change information of partially inactive timers), the scheme includes at least one of the following:

[0263] 1. If the BWP inactivity timer expires within the skipping duration and the inactive timer portion of the bandwidth expires, the terminal performs at least one of the following:

[0264] (1) Terminating the skipping duration means that the terminal stops skipping the PDCCH listening behavior. This corresponds to the terminal clearing the remaining skipped PDCCH listening duration.

[0265] (2) Continue skipping duration, which means that the PDCCH listening behavior will continue to be skipped on the target BWP after the switch. This corresponds to the terminal continuing to run the skipped PDCCH listening duration.

[0266] 2. If the BWP inactivity timer starts or restarts within the skipped duration, the terminal continues to run the current skipped duration. This corresponds to the terminal continuing to run the skipped PDCCH listening duration as described above.

[0267] Part Four: The R17 SSSG handover scheme combined with the BWP timer (corresponding to the case of at least two types of channel monitoring information, including the first type of search space group handover information and the state change information of some bandwidth inactive timers), the scheme includes at least one of the following:

[0268] 1. If the BWP inactivity timer expires, the terminal performs at least one of the following (corresponding to the first operation above):

[0269] (1) The current search space group is no longer applied, and PDCCH listening on the current search space group is stopped. The specific listening behavior to be followed is not limited here; for example, an initial PDCCH listening behavior could be defined after each BWP switch. Specifically, the terminal could switch to the default search space group and perform the corresponding listening behavior.

[0270] (2) Reset (or restart) the R17 search space group switching timer. This corresponds to restarting the first type of search space group switching timer as described above.

[0271] (3) Continue to use the current search space group, that is, the terminal continues to listen for PDCCH on the current search space group (until the R17 search space group switching timer expires or the R17 search space group switching instruction is received on the target BWP and switched to another search space group).

[0272] (4) Do not restart (i.e. continue running) the R17 search space group switching timer. This corresponds to the first type of search space group switching timer that continues to run as described above.

[0273] 2. If the BWP inactivity timer starts or restarts, the terminal can continue to use the current search space group.

[0274] Part Five: The R17 PDCCH skipping scheme combined with DRX-related timers (corresponding to the case where at least two types of channel monitoring information are mentioned above, including PDCCH skipping information and DRX-related timer status change information), including at least one of the following:

[0275] 1. If the DRX timer expires, starts, or restarts within the skipping duration, the skipping duration will continue, meaning the terminal will continue to skip PDCCH listening.

[0276] 2. If the DRX timer starts or restarts during the skipping duration, the skipping duration will be stopped, meaning the terminal will stop skipping PDCCH listening. This corresponds to the terminal clearing the remaining skipped PDCCH listening duration mentioned above.

[0277] Part Six: The R17 SSSG handover scheme is combined with DRX-related timers (corresponding to the situation where at least two types of channel monitoring information are mentioned above, including Type I search space group handover information and DRX-related timer status change information), and the scheme includes at least one of the following:

[0278] 1. When the DRX timer starts or restarts, the current search space group continues to be applied, meaning the terminal continues to listen for PDCCH on the current search space group;

[0279] 2. When the DRX timer is started or restarted, switch to the default search space, and the terminal will listen for PDCCH on the default search space group.

[0280] 3. If the DRX timer expires, the current search space group will continue to be used, but the terminal will not perform the corresponding PDCCH listening operation on the current search space group, that is, PDCCH listening will not be performed.

[0281] 4. When the DRX timer expires, switch to the default search space group, but do not perform the corresponding PDCCH listening operation on the default search space group, that is, do not perform PDCCH listening.

[0282] In addition, the aforementioned DRX timer (or DRX-related timer) includes at least one of the following: DRX onduration timer, DRX inactivity timer, DRX retransmission timer, and DRX RTT (round-trip time) timer.

[0283] As shown above, this solution can achieve channel monitoring for various channel monitoring information. Specifically, this solution provides a combination of the R16SSSG handover scheme and the R17 PDCCH monitoring adaptation scheme, clarifies the UE's relevant behaviors for PDCCH monitoring, and improves communication performance.

[0284] The channel monitoring method provided in this application can be executed by a channel monitoring device. This application uses an example of a channel monitoring device executing the channel monitoring method to illustrate the channel monitoring device provided in this application.

[0304] Optionally, the first execution module 102 is further configured to: listen to the PDCCH in a third search space, wherein the third search space is the search space associated with the search space group activated in the first type of search space group and / or the search space group activated in the second type of search space group.

[0305] The search spaces associated with the first search space group and the second search space group may be the same or different; the identifiers of the first search space group and the second search space group are the same, the first search space group is the search space group associated with the first type of search space group switching information, and the second search space group is the search space group associated with the second type of search space group switching information.
