[0026] A search space set group can be unassociated with any search space (which can be understood as a collection of search spaces) or associated with at least one search space.

[0027] In addition, when the timer associated with the search space group (SSSG timer) expires, the terminal switches to the default search space group (default SSSG) or search space group #0.

[0029] The reference determination method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0030] Figure 2 A flowchart illustrating a reference determination method provided in an embodiment of this application is shown. Figure 2 As shown, the reference determination method provided in this application embodiment may include the following steps 201 and 202:

[0031] Step 201: The communication device acquires the first information.

[0032] The aforementioned communication equipment includes at least one of the following: a terminal, or a network-side device.

[0033] It should be noted that the reference determination method provided in this application embodiment is applicable to both terminal and network-side devices.

[0034] The first information mentioned above is used to configure at least one of the following: multiple associated downlink physical control channel (PDCCH) candidates, and multiple associated PDCCH listening times (PDCCH MOs).

[0035] In this embodiment, multiple associated downlink physical control channel (PDCCH) candidates are used as examples. Furthermore, it is understood that the timing of multiple associated PDCCH monitoring can also be applied to subsequent embodiments, and will not be repeated here.

[0036] In this embodiment of the application, the first information mentioned above includes: configuration information of multiple associated PDCCH candidates.

[0037] In the embodiments of this application, the aforementioned plurality of associated PDCCH candidates include at least two PDCCH candidates.

[0038] It should be noted that a PDCCH candidate (or, may also be called a candidate PDCCH) is the set of all possible locations where a PDCCH may occur, including all PDCCH candidates in the search space of the network configuration.

[0039] In the embodiments of this application, the above-mentioned multiple associated PDCCH listening times include at least two PDCCH listening times.

[0040] For example, the network-side device may transmit the same DCI in any one or more of the aforementioned associated PDCCH candidates. It is also understood that the terminal may assume that the DCI received in the aforementioned associated PDCCH candidates is the same DCI. For ease of description, the associated PDCCH candidates in this example will be referred to as PDCCH retransmissions, i.e., retransmitted PDCCHs.

[0041] Step 202: The communication device determines the first reference based on the first information mentioned above.

[0042] The aforementioned first reference includes at least one of the following:

[0043] PDCCH monitoring adapts to the application latency of the indication;

[0044] The timer associated with the search space group starts or restarts;

[0045] Application delay of discontinuous reception of DRX start offset indication;

[0046] PDCCH monitoring adaptation indication is active or applied;

[0047] The DRX starting offset indicator is active or applied;

[0048] The minimum K0 / K2 indicates the application latency, where K0 refers to the slot-level distance between the PDCCH and the PDSCH it schedules, for example, K0 = 1 slot. K2 refers to the slot-level distance between the PDCCH and the PUSCH it electroplats, for example, K2 = 1 slot.

[0049] The first reference mentioned above is related to the first PDCCH candidate, and the first PDCCH candidate is included among the multiple associated PDCCH candidates.

[0050] It should be noted that the timer associated with a search space group can be understood as a timer related to the switching of the search space group. Multiple search space groups can share the same timer, or different search space groups can each have their own specific timer.

[0051] In one possible embodiment, the first reference described above is used to determine at least one of the following: the start time of the application delay of the PDCCH listener adaptation indication, the start or restart time of the timer associated with the search space group, the start time of the application delay of the DRX start offset indication, the time when the PDCCH listener adaptation indication (start) takes effect or is applied, the time when the DRX start offset indication (start) takes effect or is applied, and the start time of the application delay of the minimum K0 / K2 indication.

[0052] For example, when the first reference is used to determine the start time or application time of the PDCCH listening adaptation indication, the application delay of the PDCCH listening adaptation indication can be equivalent to 0.

[0053] In the embodiments of this application, the first PDCCH candidate can be one of a plurality of associated PDCCH candidates. For example, in the case of repeated PDCCH transmission, the first PDCCH candidate can be one of a plurality of repeated PDCCH candidates.

[0054] In the reference determination method provided in this application embodiment, the communication device obtains first information, which is used to configure multiple associated PDCCH candidates, and determines a first reference based on the first information, including at least one of the following: the application delay of the PDCCH listening adaptation indication, the start or restart of the timer associated with the search space group, and the application delay of the discontinuous reception DRX start offset indication; the PDCCH listening adaptation indication being active or applied; and the DRX start offset indication being active or applied. The first reference is related to a first PDCCH candidate, and the first PDCCH candidate is included among the multiple associated PDCCH candidates. Through this method, when the communication device includes a terminal and a network-side device, the terminal and network-side device can determine the first reference for the application delay of the PDCCH listening adaptation indication, the start or restart of the timer associated with the search space group, and the application delay of the discontinuous reception DRX start offset indication based on the first information, ensuring consistency in understanding between the terminal and the network side, and improving network reliability and robustness.

[0055] In some possible embodiments, the first reference mentioned above includes at least one of a reference point and a reference PDCCH candidate, wherein the reference PDCCH candidate is the first PDCCH candidate mentioned above.

[0056] Optionally, the first reference mentioned above is used for at least one of the following: the application delay of the PDCCH listener adaptation indicator, the start or restart of the timer associated with the search space group, the application delay of the DRX start offset indicator, the PDCCH listener adaptation indicator, and the DRX start offset indicator.

[0057] Optionally, the first PDCCH candidate mentioned above is the earliest or latest PDCCH candidate among the multiple associated PDCCH candidates.

[0058] For example, in the case of repeated PDCCH transmission, the first PDCCH candidate mentioned above may correspond to the earliest or latest PDCCH candidate among the repeated PDCCH candidates.

[0059] In some other possible embodiments, the first reference mentioned above includes a reference to the PDCCH listening timing.

[0060] Optionally, the aforementioned reference PDCCH listening time is the earliest or latest PDCCH listening time among multiple associated PDCCH listening times.

[0061] Thus, under multiple associated PDCCH candidate configurations, the terminal uses the earliest or latest PDCCH candidate among the multiple associated PDCCH candidates as a reference to determine at least one of the following: the application delay of the PDCCH listening adaptation indication, the start or restart time of the timer associated with the search space group, and the application delay of the discontinuous reception DRX start offset indication. This enables the terminal to determine, for example, in the case of repeated PDCCH transmission, the starting position of the application delay of the PDCCH listening adaptation indication or the start time of the timer associated with the search space group, the application time of the PDCCH listening adaptation indication, the application time of the DRX start offset indication, etc., avoiding inconsistencies between the terminal and the network side, and improving network reliability and robustness.

[0062] Optionally, in embodiments of this application, when the first reference includes a reference point, the reference point includes at least one of the following:

[0063] The above reference point is the start or end time of the first time unit in which the first PDCCH candidate is located;

[0064] The above reference point is the start or end time of the next time unit after the first time unit in which the first PDCCH candidate is located.

[0065] Optionally, the first time unit mentioned above is at least one of the following: symbol, slot, millisecond, radio frame, and subframe.

[0066] For example, if there is no interval between the first time unit and the next time unit in which the first time unit is located, the end time of the first time unit is the start time of the next time unit.

[0067] Taking the example of the first PDCCH candidate being the latest PDCCH candidate among multiple related PDCCH candidates, the above reference point is illustrated as follows:

[0068] In one example, in the case of repeated PDCCH transmissions, the above reference point is the start time of the time slot containing the latest PDCCH candidate among the repeated PDCCH candidates.

[0069] In another example, in the case of repeated PDCCH transmissions, the above reference point is the start time of the next time slot of the time slot containing the latest PDCCH candidate among the repeated PDCCH candidates.

[0070] In another example, in the case of repeated PDCCH transmissions, the above reference point is the end time of the next time slot of the time slot containing the latest PDCCH candidate among the repeated PDCCH candidates.

[0071] In some possible embodiments, the above reference point may include at least one of the following:

[0072] The start or end time of the first time unit in which the first PDCCH is monitored;

[0073] The first PDCCH listening time is the start or end time of the next time unit after the first time unit.

[0074] Optionally, the first PDCCH listening time mentioned above is the earliest or latest PDCCH listening time among multiple associated PDCCH listening times.

[0075] Taking the first PDCCH listening time as the earliest PDCCH listening time among multiple related PDCCH listening times as an example, the above reference point is illustrated as follows:

[0076] In one example, in the case of repeated PDCCH transmissions, the above reference point is the start time of the time slot of the earliest PDCCH listening opportunity among the repeated PDCCH listening opportunities.

[0077] Thus, in the case of repeated PDCCH transmission, the communication device uses the start or end time of the time unit (such as the time slot) of the first PDCCH candidate among multiple associated PDCCH candidates or the first PDCCH listening time among multiple associated PDCCH listening times as the reference point for determining the application delay of the PDCCH listening adaptation indication, the timer associated with the search space group, and the application delay of the DRX start offset adjustment indication. This ensures that the terminal and the network side have a consistent understanding, improving network reliability and robustness.

[0078] Optionally, the value of the first time unit in the first case differs from the value in the second case. The first case includes situations where the time span occupied by the plurality of associated PDCCH candidates does not exceed one time slot, and the second case includes situations where the time span occupied by the plurality of associated PDCCH candidates exceeds one time slot. In other words, the value of the first time unit differs when the time span occupied by the plurality of associated PDCCH candidates does not exceed one time slot compared to when the time span occupied by the plurality of associated PDCCH candidates exceeds one time slot.

[0079] For example, the time span of the above-mentioned multiple associated PDCCH candidates not exceeding one time slot can be understood as: multiple associated PDCCH candidates are repeatedly transmitted within one time slot (i.e., Intra slot repetition); the time span of the above-mentioned multiple associated PDCCH candidates exceeding one time slot can be understood as: multiple associated PDCCH candidates are repeatedly transmitted in multiple time slots (i.e., Inter slot repetition).

[0080] For example, in the case of repeated PDCCH transmission, if multiple PDCCHs are repeatedly transmitted within one time slot, the first time unit can be a time slot; if multiple PDCCHs are repeatedly transmitted within three time slots, the first time unit can be a millisecond.

[0081] In some possible embodiments, the value of the first time unit in a first case is different from the value in a second case. The first case includes: the time span occupied by the plurality of associated PDCCH candidates does not exceed one time slot. The second case includes: the time span occupied by the plurality of associated PDCCH candidates exceeds one time slot. That is, the first time unit when the time span occupied by the plurality of associated PDCCH listening opportunities does not exceed one time slot is different from the first time unit when the time span occupied by the plurality of associated PDCCH listening opportunities exceeds one time slot.

[0082] In this way, the terminal can determine the granularity of the first time unit based on the time span occupied by multiple associated PDCCH candidates or PDCCH listening opportunities. That is, different time unit granularities can be used when occupying different time spans, thereby improving network transmission performance.

[0083] Optionally, in the embodiments of this application, the DCI corresponding to the PDCCH carried by the above-mentioned plurality of associated PDCCH candidates includes at least one of the above-mentioned PDCCH listening adaptation indication and the above-mentioned DRX start offset indication.

[0084] For example, the DCI corresponding to the PDCCH carried by the above-mentioned multiple associated PDCCH candidates can be understood as: the DCI corresponding to one or more PDCCHs detected by the terminal among the multiple associated PDCCH candidates.

[0085] For example, in the case of repeated PDCCH transmission, the downlink control information (DCI) carried by the PDCCH detected by the terminal among the above-mentioned multiple associated PDCCH candidates includes at least one of the above-mentioned PDCCH listening adaptation indication and the above-mentioned DRX start offset indication.

[0086] It should be noted that in the case of repeated PDCCH transmission, the DCI corresponding to the PDCCH carried by multiple associated PDCCH candidates is the same.

[0087] Thus, when at least one of the PDCCH adaptation indication and DRX start offset indication is transmitted on the aforementioned multiple associated PDCCH candidates, the method for determining the first reference point proposed in this application can avoid problems such as inconsistency in understanding between the terminal and the network side, which could lead to poor transmission reliability.

[0088] Optionally, in this embodiment of the application, the process of determining the first reference for the application latency of the PDCCH listening adaptation indication based on the first information in step 202 above may include the following step 203a:

[0089] Step 203a: The communication device determines the start time of the application delay of the PDCCH listening adaptation indication based on the first reference.

[0090] Optionally, the above PDCCH listening adaptation indication includes at least one of the following: PDCCH skip indication, search space group switching indication.

[0091] For example, when the above PDCCH monitoring adaptation indication includes a PDCCH skip indication, the PDCCH monitoring adaptation indication is used by the terminal to determine that it will not monitor a specific type of PDCCH within a certain time interval.

[0092] For example, when the above-mentioned PDCCH monitoring adaptation indication includes a search space group switching indication, the PDCCH monitoring adaptation indication is used for the terminal to obtain the search space group switching indication, so that the terminal can perform PDCCH monitoring on the corresponding active search space group according to the search space group switching indication.

[0093] The following uses a communication device as an example to further illustrate the reference determination method provided in this application:

[0094] Optionally, the terminal determines the start time of the application delay of the PDCCH listening adaptation indication based on the first reference. At that start time, the terminal enters the application delay of the PDCCH listening adaptation indication.

[0095] For example, taking a first reference point as an example, the terminal determines the start time of the application delay of the PDCCH listening adaptation indication based on this reference point. At this start time, the terminal enters (or can begin) the application delay of the PDCCH listening adaptation indication.

[0096] For example, if the first reference is the start time of the time slot where the first PDCCH candidate is located, the terminal enters the application delay of the PDCCH listening adaptation indication at the start time of the time slot where the first PDCCH candidate is located.

[0097] Optionally, the PDCCH listening adaptation indicator takes effect or is applied after the application delay of the PDCCH listening adaptation indicator has ended.

[0098] The following uses a communication device as an example to further illustrate the reference determination method provided in this application:

[0099] In one example, the terminal determines the end time of the symbol containing the latest PDCCH candidate among multiple associated PDCCH candidates as the reference point for the application delay of the PDCCH listening adaptation indication. The application delay of the PDCCH listening adaptation indication begins after this reference point, and the PDCCH adaptation indication becomes effective after the application delay of the PDCCH listening adaptation indication ends.

[0100] In another example, the terminal determines the end time of the symbol containing the last PDCCH MO among multiple associated PDCCH MOs as the reference point for the PDCCH listener adaptation indication application delay. The application delay of the PDCCH listener adaptation indication begins after the reference point, and the PDCCH adaptation indication becomes effective after the application delay of the PDCCH listener adaptation indication ends.

[0101] For example, such as Figure 3 As shown, the terminal performs repeated PDCCH transmissions on two PDCCH MOs (i.e., MO1 and MO2). The UE determines the end time of the symbol containing MO2 as the Reference point, or the UE uses MO2 as the reference MO. Based on the reference point or reference MO, the start time of the application delay is determined. The terminal enters the application delay at the determined start time, and the PDCCH adaptation indication takes effect after the application delay ends. MO1 and MO2 are located in one slot (i.e., slot A), and MO1 and MO2 each occupy one symbol (i.e., symbol A). The DCIs corresponding to the PDCCHs carried on MO1 and MO2 carry the same PDCCH listening adaptation indication.

[0102] It is understandable that replacing PDCCH MO in the above example with a PDCCH candidate is also feasible, in which case PDCCH candidate 2 would be the reference PDCCH candidate. Detailed descriptions will not be repeated here.

[0103] For example, in the case of repeated PDCCH transmissions, multiple associated PDCCH candidates include two PDCCH candidates. The terminal determines the end time of the symbol containing the second PDCCH candidate as the Reference point. The application delay begins after the Reference point, and the PDCCH adaptation indication takes effect after the application delay ends.

[0104] In this way, the terminal starts the application delay of the PDCCH listening adaptation indication after the reference point, and makes the PDCCH listening adaptation indication effective after the application delay of the PDCCH listening adaptation indication ends, thereby improving network reliability and robustness.

[0105] Optionally, in this embodiment of the application, the step 202 above, in which the terminal determines the first reference for starting or restarting the timer associated with the search space group based on the first information, may include the following step 203b:

[0106] Step 203b: The communication device determines the start or restart time of the timer associated with the search space group based on the first reference.

[0107] The following uses a communication device as an example to illustrate the reference determination method provided in this application:

[0108] Optionally, the terminal determines the start time of the timer associated with the search space group based on the first reference. At that start time, the terminal starts the timer associated with the search space group.

[0109] For example, in the case of repeated PDCCH transmission, multiple associated PDCCH candidates include two PDCCH candidates. The terminal determines the end time of the symbol containing the second PDCCH candidate as the reference point, and starts the timer associated with the search space group at the start time determined according to the reference point.

[0110] In this way, the terminal starts the timer associated with the search space group at the start time determined according to the reference point, thereby improving network reliability and robustness.

[0111] Optionally, in this embodiment of the application, the step 202 in which the terminal determines the first reference for the application latency indicated by the DRX start offset based on the first information may include the following step 203c:

[0112] Step 203c: The communication device determines the start time of the application delay indicated by the DRX start offset based on the first reference.

[0113] The following uses a communication device as an example to illustrate the reference determination method provided in this application:

[0114] Optionally, the terminal determines the start time of the application delay indicated by the DRX start offset based on the first reference. At this start time, the terminal enters the PDCCH listening adaptation phase for the indicated application delay.

[0115] For example, in the case of repeated PDCCH transmissions, multiple associated PDCCH candidates include two PDCCH candidates. The terminal determines the end time of the symbol containing the second PDCCH candidate as the Reference point, and starts the application delay indicated by the DRX start offset at the start time of the application delay determined according to the Reference point.

[0116] In this way, the application delay of the DRX start offset indication after the reference point is reduced, avoiding inconsistencies between the terminal and the network side, and improving network reliability and robustness.

[0117] Optionally, in this embodiment of the application, the step 202 in which the terminal determines the first reference for the PDCCH listening adaptation indication to take effect or be applied based on the first information may include the following step 203d:

[0118] Step 203d: The communication device determines the effective or application time of the PDCCH listening adaptation indication based on the first reference.

[0119] The following uses a communication device as an example to illustrate the reference determination method provided in this application:

[0120] Optionally, the terminal determines the effective or applied time of the PDCCH listening adaptation indication based on a first reference. The PDCCH listening adaptation indication begins to take effect or be applied at this effective or applied time.

[0121] For example, in the case of repeated PDCCH transmission, multiple associated PDCCH candidates include two PDCCH candidates. The terminal determines the end time of the symbol containing the second PDCCH candidate as the Reference point, and at the effective time determined according to this Reference point, the PDCCH listening adaptation indication begins to take effect.

[0122] In this way, the terminal determines whether the PDCCH listening adaptation indication is effective or applied after the reference point, avoiding inconsistencies between the terminal and the network side, and improving network reliability and robustness.

[0123] Optionally, in this embodiment of the application, the step 202 in which the terminal determines the first reference for the PDCCH listening adaptation indication to take effect or be applied based on the first information may include the following step 203d:

[0124] Step 203e: The communication device determines the effective or applied time of the DRX start offset indication based on the first reference.

[0125] The following uses a communication device as an example to illustrate the reference determination method provided in this application:

[0126] Optionally, the terminal determines the effective or applied time of the DRX start offset indication based on a first reference. At this effective or applied time, the DRX start offset indication begins to take effect or be applied.

[0127] For example, in the case of repeated PDCCH transmissions, multiple associated PDCCH candidates include two PDCCH candidates. The terminal determines the start time of the symbol containing the first PDCCH candidate as the Reference point, and the DRX start offset indication takes effect at the effective time determined according to this Reference point.

[0128] In this way, the terminal determines whether the PDCCH listening adaptation indication is effective or applied after the reference point, avoiding inconsistencies between the terminal and the network side, and improving network reliability and robustness.

[0129] The reference determination method provided in this application can be executed by a reference determination device. This application uses an example of a reference determination device executing the reference determination method to illustrate the reference determination device provided in this application.

[0130] Figure 4 The present application provides a possible structural schematic diagram of a reference determination device, which includes an acquisition module 401 and a determination module 402, wherein: the acquisition module 401 is used to acquire first information, the first information being used to configure a plurality of associated PDCCH candidates; the determination module 402 is used to determine a first reference based on the first information acquired by the acquisition module 401, including at least one of the following:

[0131] PDCCH monitoring adapts to the application latency of the indication;

[0132] The timer associated with the search space group starts or restarts;

[0133] Application delay of discontinuous reception of DRX start offset indication;

[0134] The first reference mentioned above is related to the first PDCCH candidate, and the first PDCCH candidate is included among the plurality of associated PDCCH candidates.

[0135] In the reference determination apparatus provided in this application embodiment, the reference determination apparatus acquires first information, which is used to configure multiple associated PDCCH candidates, and determines a first reference based on the first information, including at least one of the following: the application delay of the PDCCH listening adaptation indication, the start or restart of the timer associated with the search space group, and the application delay of the discontinuous reception DRX start offset indication; wherein the first reference is related to a first PDCCH candidate, and the first PDCCH candidate is included among the multiple associated PDCCH candidates. Through this method, in the case of repeated PDCCH transmission, the reference determination apparatus can determine the reference points for the application delay of the PDCCH listening adaptation indication, the start or restart of the timer associated with the search space group, and the application delay of the discontinuous reception DRX start offset indication based on the first information, ensuring consistency between the terminal and the network side in understanding, and improving network reliability and robustness.

[0136] Optionally, in the embodiments of this application, the first reference includes at least one of a reference point and a reference PDCCH candidate, and the reference PDCCH candidate includes the first PDCCH candidate.

[0137] Optionally, in embodiments of this application, when the first reference includes a reference point, the reference point includes at least one of the following:

[0138] The reference point mentioned above refers to the start or end time of the first time unit in which the first PDCCH candidate is located.

[0139] The reference point mentioned above is the start or end time of the next time unit after the first time unit in which the first PDCCH candidate is located.

[0140] Thus, in the case of repeated PDCCH transmission, the terminal determines the reference point for the application delay of the PDCCH listening adaptation indication, the timer associated with the search space group, and the application delay of the DRX start offset adjustment indication based on the start or end time of the first PDCCH candidate among multiple PDCCH candidates or the time unit (such as the time slot) where the first PDCCH listening opportunity is located among multiple PDCCH listening opportunities. This clarifies the timing of entering the application delay and starting the timer, ensuring that the terminal and the network side have consistent understanding and improving network reliability and robustness.

[0141] Optionally, in the embodiments of this application, the first PDCCH candidate is the earliest or latest PDCCH candidate among the plurality of associated PDCCH candidates.

[0142] Thus, in the case of repeated PDCCH transmission, the terminal uses the earliest or latest PDCCH in time among the repeated PDCCHs as a reference for the application delay of the PDCCH listening adaptation indication, the start or restart of the timer associated with the search space group, and the application delay of the discontinuous reception DRX start offset indication. This allows the terminal to determine when to enter the application delay of the PDCCH listening adaptation indication and to start or restart the timer associated with the search space group in the case of repeated PDCCH transmission, avoiding inconsistencies between the terminal and the network side and improving network reliability and robustness.

[0143] Optionally, in this embodiment of the application, the determining module is further configured to determine the start time of the application delay of the PDCCH listening adaptation indication based on the first reference.

[0144] In this way, the terminal starts the application delay of the PDCCH listening adaptation indication after the reference point, and makes the PDCCH listening adaptation indication effective after the application delay of the PDCCH listening adaptation indication ends, thereby improving network reliability and robustness.

[0145] Optionally, in this embodiment of the application, the determining module is further configured to determine the timer start time or restart time associated with the search space group based on the first reference.

[0146] In this way, the terminal starts the timer associated with the search space group after the reference point, improving network reliability and robustness.

[0147] Optionally, in this embodiment of the application, the determining module is further configured to determine the start time of the application delay indicated by the DRX start offset based on the first reference.

[0148] In this way, the application delay of the DRX start offset indication after the reference point is reduced, avoiding inconsistencies between the terminal and the network side, and improving network reliability and robustness.

[0149] Optionally, in the embodiments of this application, the above-mentioned PDCCH listening adaptation indication includes at least one of the following: PDCCH skip indication, search space group switching indication.

[0150] Optionally, in the embodiments of this application, the DCI corresponding to the PDCCH carried by the above-mentioned plurality of associated PDCCH candidates includes at least one of the PDCCH listening adaptation indication and the DRX start offset indication.

[0151] Optionally, in the embodiments of this application, the first time unit can be at least one of a symbol, a time slot, a millisecond, a subframe, and a radio frame.

[0152] Optionally, in this embodiment, the value of the first time unit in a first case differs from its value in a second case. The first case includes: the time span occupied by the plurality of associated PDCCH candidates does not exceed one time slot; the second case includes: the time span occupied by the plurality of associated PDCCH candidates exceeds one time slot. That is, the value of the first time unit is different when the time span occupied by the plurality of associated PDCCH candidates does not exceed one time slot compared to when the time span occupied by the plurality of associated PDCCH candidates exceeds one time slot.

[0153] In this way, the terminal can determine the granularity of the first time unit based on the time span occupied by multiple associated PDCCH candidates or PDCCH listening opportunities. That is, different time unit granularities can be used when occupying different time spans, thereby improving network transmission performance.
