[0002] A Discontinuous Reception (DRX) mechanism is introduced in a mobile communication system such as a Long Term Evolution (LTE) system or a New Radio (NR) system. Thus, the purpose of power saving of a User Equipment (UE; may also be called a terminal device, a user terminal, a mobile terminal, etc.) is achieved by setting a DRX on time and a DRX off time.

[0003] When configuring DRX, the UE configures parameters such as a connected mode DRX on-duration timer (onDurationTimer), a DRX inactivity timer (drx-InactivityTimer), a DRX retransmission timer (drx-Retransmission Timer), and a long DRX cycle start offset (longDRX-Cycle Start Offset).

[0021] Referring to FIG. 2, an embodiment of the present application provides a method for intercepting a physical downlink control channel performed by a terminal device, where the terminal device includes a UE of R17 version or later, and the method includes the following steps:

Further, optionally, the DCI format corresponding to the downlink grant includes at least one of DCI format 1_1, DCI format 1_2, and DCI format 1_0.

[0037] (8) Bandwidth Part (BWP). Optionally, the BWP belongs to a corresponding BWP set, where the BWP set includes at least one BWP.

[0038] Optionally, in the physical downlink control channel interception method of the embodiment of the present application, the first object includes two or more of the above (1) to (8).

[0039] In addition, in the terminal device, at least two CDRX processes are configured for at least two (sets) of DCI formats (S), and at least one parameter value is different in the two CDRX processes; at least two CDRX processes are configured for at least two (sets) of RNTI (S), and at least one parameter value is different in the two CDRX processes; at least two CDRX processes are configured for at least two (sets) of search spaces (S), and at least one parameter value is different in the two CDRX processes; at least two CDRX processes are configured for at least two (sets) of CORESET (S), and at least one parameter value is different in the two CDRX processes; and at least two CDRX processes are configured for at least two (sets) of BWP (S), and at least one parameter value is different in the two CDRX processes.

[0040] In the embodiment of the present application, different connected mode discontinuous reception DRX parameters can be obtained according to the received configuration information, that is, the configuration information can indicate the correspondence between multiple sets of CDRX parameters and multiple target objects, and the multiple target objects can be different objects belonging to the same type or different types, and the associated PDCCHs can be intercepted according to the CDRX parameters corresponding to the different objects. In this way, the PDCCHs associated with different objects can be intercepted in different intercept modes according to the configuration of different CDRX parameters, which avoids unnecessary blind detection of PDCCHs, avoids waste of power of terminal equipment, and saves power consumption of the terminal.

[0041] Optionally, the method for intercepting a physical downlink control channel of the embodiment of the present application may further include: when a PDCCH associated with the first object of a new transmission is received during an operation of a CDRX on-duration timer corresponding to the first object, the terminal device starts or restarts a CDRX inactivity timer corresponding to the first object. That is, the CDRX inactivity timer corresponding to the first object is started or restarted only when a condition is satisfied that a PDCCH corresponding to the first object of a new transmission is received during an operation of a CDRX on-duration timer corresponding to the first object.

[0042] It should be noted that the above new transmission may refer to a first transmission or an initial transmission, and the PDCCH corresponding to the first object of the above new transmission is for a retransmitted or non-initial transmitted PDCCH.

[0043] Furthermore, optionally, in the physical downlink control channel interception method of the embodiment of the present application, when a PDCCH different from the PDCCH associated with the first object is received during the operation of a CDRX on-duration timer corresponding to the first object, the terminal device may further include not starting or restarting a CDRX inactivity timer corresponding to the first object.

[0044] Optionally, in the physical downlink control channel interception method of the embodiment of the present application, when a PDCCH associated with the first object is not received in a target time unit during the operation of a CDRX inactivity timer corresponding to the first object, the terminal device may further include continuously operating a CDRX inactivity timer corresponding to the first object.

[0045] Optionally, the target time unit may include a slot, or 1 millisecond, or the like.

[0046] Optionally, when receiving target signaling corresponding to the first object, stop a CDRX inactivity timer corresponding to the first object and stop a CDRX on-duration timer corresponding to the first object, where the target signaling corresponding to the first object is a DRX Command MAC control element (CE), or a Long DRX Command MAC CE, or other type of signaling.

[0047] Alternatively, when a target signaling is received, stop the CDRX inactivity timers corresponding to all objects and stop the CDRX on-duration timers corresponding to all the objects, where the target signaling is a DRX Command MAC control element (CE), or a Long DRX Command MAC CE, or other type of signaling.

[0048] Hereinafter, with reference to another example, a method for intercepting PDCCHs associated with different objects in different intercept modes according to different CDRX parameter settings in an embodiment of the present application will be described, and the basic idea of ​​the method in the embodiment of the present application is as follows: For each cell group (CG), such as a master cell group (MCG) or a secondary cell group (SCG), the terminal device UE has two sets of CDRX parameters DRX-inactivity timer (i.e., CDRX inactivity timer) and onduration timer (i.e., CDRX onduration timer), each of which corresponds to at least two (pairs) of objects such as DCI format(S), and each (pair) of objects has its own parameter value, and the two sets of parameters operate independently.

[0049] In example 1, the CDRX parameters DRX-inactivity timer and onduration timer have their own parameters for DCI format 0_1 ​​and DCI format 1_1, respectively, that is, the first object and the second object are different DCI formats, and the details are as follows: (1)DRX-inactivitytimer for DCI format 0_1. (2) Onduration timer for DCI format 0_1. (3)DRX-inactivitytimer for DCI format 1_1. (4) Onduration timer for DCI format 1_1. (5) Other CDRX parameters are the same as the CDRX parameters in the 3GPP (registered trademark) version 15 (R15) and version 16 (R16) standards.

[0050] For DCI format 0_1, the UE detects DCI format 0_1 ​​while the Onduration timer for DCI format 0_1 ​​is operating, and does not detect DCI format 0_1 ​​while in DRX off. If DCI format 0_1 ​​is detected, the UE starts or restarts the DRX-inactivity timer for DCI format 0_1, and if another DCI format (a DCI format other than DCI format 0_1) is detected, the UE does not start or restart the DRX-inactivity timer for DCI format 0_1, and if DCI format 0_1 ​​is not detected in the slot (i.e., the target time unit), the UE subtracts 1 from the DRX-inactivity timer for DCI format 0_1. When the DRX-inactivity timer for DCI format 0_1 ​​expires (times out) and while the Onduration timer for DCI format 0_1 ​​is not operating, the UE enters DRX off corresponding to DCI format 0_1, and does not detect DCI format 0_1 ​​at this time.

[0051] Regarding DCI format 1_1, the UE detects DCI format 1_1 while the Onduration timer for DCI format 1_1 is operating, and does not detect DCI format 1_1 while DRX off. If the UE detects DCI format 1_1, it starts or restarts the DRX-inactivity timer for DCI format 1_1, and if the UE detects another DCI format (a DCI format other than DCI format 1_1), it does not start or restart the DRX-inactivity timer for DCI format 1_1, and if the UE does not detect DCI format 1_1 in the slot (i.e., the target time unit), it subtracts 1 from the DRX-inactivity timer for DCI format 1_1. When the DRX-inactivity timer for DCI format 1_1 expires (times out) and while the Onduration timer for DCI format 1_1 is not operating, the UE enters DRX off corresponding to DCI format 1_1, and does not detect DCI format 1_1 at this time.

[0052] In example 2, the CDRX parameters DRX-inactivity timer and onduration timer have their own parameters for DCI format 0_1 ​​and DCI format 1_1, respectively, that is, the first object and the second object are different DCI formats, and there is only one Onduration timer, and the details are as follows: (1)DRX-inactivitytimer for DCI format 0_1. (2)DRX-inactivitytimer for DCI format 1_1. (3) Other CDRX parameters are the same as those of R15 and R16.

[0053] For DCI format 0_1, the UE detects PDCCH DCI format 0_1 ​​within the Onduration timer. If DCI format 0_1 ​​is detected, the UE starts or restarts the DRX-inactivity timer for DCI format 0_1. If another DCI format (a DCI format other than DCI format 0_1) is detected, the DRX-inactivity timer for DCI format 0_1 ​​is not started or restarted, and if DCI format 0_1 ​​is not detected in the slot, 1 is subtracted from the DRX-inactivity timer. When the DRX-inactivity timer for DCI format 0_1 ​​expires (times out) and the Onduration timer is not operating, the UE enters DRX off corresponding to DCI format 0_1 ​​and does not detect DCI format 0_1 ​​at this time.

[0054] For DCI format 1_1, the UE detects PDCCH DCI format 1_1 within the Onduration timer. If DCI format 1_1 is detected, the UE starts or restarts the DRX-inactivity timer for DCI format 1_1. If another DCI format (a DCI format other than DCI format 1_1) is detected, the DRX-inactivity timer for DCI format 1_1 is not started or restarted, and if DCI format 1_1 is not detected in the slot, 1 is subtracted from the DRX-inactivity timer. When the DRX-inactivity timer for DCI format 1_1 expires (times out) and the Onduration timer is not operating, the UE enters DRX off corresponding to DCI format 1_1 and does not detect DCI format 1_1 at this time.

[0055] In example 3, the CDRX parameters DRX-inactivity timer and onduration timer have their own parameters for DCI format 0_1 ​​and DCI format 1_1, respectively, that is, the first object and the second object are different DCI formats, and there is only one DRX-inactivity timer, and the details are as follows: (1) Onduration timer for DCI format 0_1. (2) Onduration timer for DCI format 1_1. (3) Other CDRX parameters are the same as those of R15 and R16.

[0056] The UE detects DCI format 0_1 ​​within the time period set in the Onduration timer for DCI format 0_1, and detects DCI format 1_1 within the time period set in the Onduration timer for DCI format 1_1. If DCI format 0_1 ​​or 1_1 is detected, the UE starts or restarts the DRX-inactivity timer. When the DRX-inactivity timer expires and the Onduration timer for DCI format 0_1 ​​is not in operation, the UE enters DRX off corresponding to DCI format 0_1 ​​and does not detect DCI format 0_1 ​​at this time. When the DRX-inactivity timer expires and the Onduration timer for DCI format 1_1 is not in operation, the UE enters DRX off corresponding to DCI format 1_1 and does not detect DCI format 1_1 at this time.

[0057] In example 4, the CDRX parameters DRX-inactivity timer and onduration timer have their own parameters for UL grant (uplink grant) and DL grant (downlink grant), respectively, that is, the first object and the second object are different UL grant or DL ​​grant, and the details are as follows: (1) DRX-inactivity timer for UL grant; the UL grant includes at least one DCI format for scheduling downlink, such as DCI format 0_1, 0_2, 0_0, etc. (2) On duration timer for UL grant; the UL grant includes at least one DCI format for scheduling downlink, such as DCI format 0_1, 0_2, 0_0, etc. (3) DRX-inactivity timer for DL ​​grant; the DL grant includes at least one DCI format of DCI format 1_1, 1_2, or 1_0. (4) Onduration timer for DLgrant; DLgrant includes at least one of DCI formats 1_1, 1_2, and 1_0. (5) Other CDRX parameters are the same as those of R15 and R16.

[0058] Regarding UL grant, the UE detects a UL grant while the Onduration timer for UL grant is operating, and does not detect a UL grant during DRX off (i.e., the time excluding the Onduration timer for UL grant in the DRX cycle). If a UL grant is detected, the UE starts or restarts the DRX-inactivity timer for UL grant. If another DCI format (not UL grant) is detected, the UE does not start or restart the DRX-inactivity timer for UL grant, and if a UL grant is not detected in the slot, the UE subtracts 1 from the DRX-inactivity timer for UL grant. When the DRX-inactivity timer for UL grant expires (times out) and the Onduration timer for UL grant is not operating, the UE enters DRX off corresponding to the UL grant, and does not detect a UL grant at this time.

[0059] Regarding DL grant, the UE detects DL grant while Onduration timer for DL ​​grant is operating, and does not detect DL grant during DRX off (i.e., the time excluding Onduration timer for DL ​​grant in the DRX cycle). If DL grant is detected, the UE starts or restarts the DRX-inactivity timer for DL ​​grant. If another DCI format (not DL grant) is detected, the DRX-inactivity timer for DL ​​grant is not started or restarted, and if DL grant is not detected in the slot, 1 is subtracted from the DRX-inactivity timer for DL ​​grant. When the DRX-inactivity timer for DL ​​grant expires (times out) and the Onduration timer for DL ​​grant is not operating, the UE enters DRX off corresponding to the DL grant, and does not detect DL grant at this time.

[0060] In Example 5, the CDRX parameters DRX-inactivity timer and onduration timer have their own parameters for UL grant (uplink grant) and DL grant (downlink grant), respectively, that is, the first object and the second object are different UL grant or DL ​​grant, and there is only one Onduration timer, and the details are as follows: (1) DRX-inactivity timer for UL grant; the UL grant includes at least one DCI format for scheduling uplink, such as DCI format 0_1, 0_2, 0_0, etc. (2) DRX-inactivity timer for DL ​​grant; the DL grant includes at least one DCI format among DCI formats 1_1, 1_2, and 1_0. (3) Other CDRX parameters are the same as those of R15 and R16.

[0061] Regarding UL grant, the UE detects the UL grant while the Onduration timer for UL grant is operating. When the UE detects the UL grant, it starts or restarts the DRX-inactivity timer for UL grant. When the UE detects another DCI format (DCI format other than UL grant), it does not start or restart the DRX-inactivity timer for UL grant, and if the UE does not detect the UL grant in the slot, it subtracts 1 from the DRX-inactivity timer for UL grant. When the DRX-inactivity timer for UL grant expires (times out) and the Onduration timer is not operating, the UE enters DRX off corresponding to the UL grant, and does not detect the UL grant at this time.

[0062] Regarding DL grant, the UE detects DL grant while the Onduration timer for DL ​​grant is operating. When a DL grant is detected, the UE starts or restarts the DRX-inactivity timer for DL ​​grant. When another DCI format (DCI format other than DL grant) is detected, the DRX-inactivity timer for DL ​​grant is not started or restarted, and if a DL grant is not detected in the slot, the DRX-inactivity timer for DL ​​grant is subtracted by 1. When the DRX-inactivity timer for DL ​​grant expires (times out) and the Onduration timer is not operating, the UE enters DRX off corresponding to the DL grant, and does not detect a DL grant at this time.

[0063] In Example 6, the CDRX parameters DRX-inactivity timer and onduration timer have their own parameters for UL grant (uplink grant) and DL grant (downlink grant), respectively, that is, the first object and the second object are different UL grant or DL ​​grant, and there is only one DRX-inactivity timer, and the details are as follows: (1) On duration timer for UL grant; the UL grant includes at least one DCI format for scheduling uplink, such as DCI format 0_1, 0_2, 0_0, etc. (2) On duration timer for DL ​​grant; DL grant includes at least one DCI format among DCI formats 1_1, 1_2, and 1_0. (3) Other CDRX parameters are the same as those of R15 and R16.

[0064] The UE detects a UL grant within the Onduration timer for UL grant and detects a DL grant within the Onduration timer for DL ​​grant. If a UL grant or DL ​​grant is detected, the UE starts or restarts the DRX-inactivity timer. When the DRX-inactivity timer expires and the Onduration timer for UL grant is not in operation, the UE enters DRX off corresponding to the UL grant and does not detect a UL grant at this time. When the DRX-inactivity timer expires and the Onduration timer for DL ​​grant is not in operation, the UE enters DRX off corresponding to the DL grant and does not detect a DL grant at this time.

[0065] In example 7, the CDRX parameters DRX-inactivity timer and onduration timer have their own parameters for DCI formats with different DCI sizes, that is, the first object and the second object are DCI formats with different DCI sizes, and the details are as follows: (1) DRX-inactivity timer for DCI size 1; DCI formats for DCI size 1 include DCI format 0_0 and 1_0. (2) DRX- Onduration timer for DCI size 1; DCI formats for DCI size 1 include DCI format 0_0 and 1_0. (3) DRX-inactivity timer for DCI size 2; DCI formats for DCI size 2 include DCI format 0_1. (4) DRX- Onduration timer for DCI size 2; DCI formats for DCI size 2 include DCI format 0_1. (5) DRX-inactivity timer for DCI size 3; DCI formats for DCI size 3 include DCI format 1_1. (6) DRX- Onduration timer for DCI size 3; DCI formats for DCI size 3 include DCI format 1_1. (7) Other CDRX parameters are the same as those of R15 and R16.

[0066] For DCI size 1, the UE detects a target DCI format including DCI formats of DCI size 1, including DCI format 0_0 and 1_0, during the operation of Onduration timer for DCI size 1, and does not detect the target DCI format during DRX off (i.e., the time excluding Onduration timer for DCI size 1 in the DRX cycle). If the target DCI format is detected, the UE starts or restarts the DRX-inactivity timer for DCI size 1, and if another DCI format (not the target DCI format) is detected, the DRX-inactivity timer for DCI size 1 is not started or restarted, and if the target DCI format is not detected in the slot, 1 is subtracted from the DRX-inactivity timer for DCI size 1. When the DRX-inactivity timer for DCI size 1 expires (times out) and while the Onduration timer for DCI size 1 is not operating, the UE enters DRX off corresponding to DCI size 1, and does not detect the target DCI format at this time.

[0067] The corresponding parameter flow for DCI size 2 and DCI size 3 is similar to that for DCI size 1, so the description will be omitted here.

[0068] In Example 8, the CDRX parameters DRX-inactivity timer and onduration timer each have their own parameters for DCI formats with different DCI sizes, i.e., the first object and the second object are DCI formats with different DCI sizes, and there is only one Onduration timer, as detailed below. (1) DRX-inactivity timer for DCI size 1; DCI formats for DCI size 1 include DCI format 0_0 and 1_0. (2) DRX-inactivity timer for DCI size 2; DCI formats for DCI size 2 include DCI format 0_1. (3) DRX-inactivity timer for DCI size 3; DCI formats for DCI size 3 include DCI format 1_1. (4) Other CDRX parameters are the same as those of R15 and R16.

[0069] For DCI size 1, the UE detects DCI formats with different DCI sizes set by the base station while the Onduration timer is operating. If the target DCI format is detected, the DRX-inactivity timer for DCI size 1 is started or restarted, and the target DCI format includes DCI formats with DCI size 1, including DCI formats 0_0 and 1_0. If another DCI format (not the target DCI format) is detected, the DRX-inactivity timer for DCI size 1 is not started or restarted, and if the target DCI format is not detected in the slot, 1 is subtracted from the DRX-inactivity timer for DCI size 1. When the DRX-inactivity timer for DCI size 1 expires (times out) and the Onduration timer is not operating, the UE enters DRX off corresponding to DCI size 1, and does not detect the target DCI format at this time.

[0070] The corresponding parameter flow for DCI size 2 and DCI size 3 is similar to that for DCI size 1, so the description will be omitted here.

[0071] In Example 9, the CDRX parameters DRX-inactivity timer and onduration timer each have their own parameters for DCI formats with different DCI sizes, i.e., the first object and the second object are DCI formats with different DCI sizes, and there is only one DRX-inactivity timer, as detailed below. (1) DRX- Onduration timer for DCI size 1; DCI formats for DCI size 1 include DCI format 0_0 and 1_0. (2) DRX- Onduration timer for DCI size 2; DCI formats for DCI size 2 include DCI format 0_1. (3) DRX- Onduration timer for DCI size 3; DCI formats for DCI size 3 include DCI format 1_1. (4) Other CDRX parameters are the same as those of R15 and R16.

[0072] The UE detects a first target DCI format including DCI formats of DCI size 1 including DCI format 0_0 and 1_0 within the time of Onduration timer for DCI size 1, detects a second target DCI format including DCI formats of DCI size 2 including DCI format 0_1 ​​within the time of Onduration timer for DCI size 2, and detects a third target DCI format including DCI formats of DCI size 3 including DCI format 1_1 within the time of Onduration timer for DCI size 3. When the first, second or third target DCI format is detected, the DRX-inactivity timer is started or restarted. When the DRX-inactivity timer expires and while the Onduration timer for DCI size 1 is not operating, the UE enters DRX off corresponding to the first target DCI format and does not detect the first target DCI format at this time. When the DRX-inactivity timer expires and while the Onduration timer for DCI size 2 is not operating, the UE enters DRX off corresponding to the second target DCI format and does not detect the second target DCI format.When the DRX-inactivity timer expires and while the Onduration timer for DCI size 3 is not operating, the UE enters DRX off corresponding to the third target DCI format and does not detect the third target DCI format.

[0073] In example 10, the CDRX parameters DRX-inactivity timer and onduration timer have their own parameters for different BWPs, for example, the first object and the second object are BWP1 and BWP2, and the details are as follows: (1)DRX-inactivitytimer for BWP1. (2) Onduration timer for BWP1. (3)DRX-inactivitytimer for BWP2. (4) Onduration timer for BWP2. (5) Other CDRX parameters are the same as those of R15 and R16.

[0074] For BWP1, the UE detects BWP1 while the Onduration timer for BWP1 is operating, and does not detect BWP1 while DRX off. If BWP1 is detected, the UE starts or restarts the DRX-inactivity timer for BWP1. If another BWP (a BWP other than BWP1) is detected, the UE does not start or restart the DRX-inactivity timer for BWP1, and if BWP1 is not detected in the slot (i.e., the target time unit), the UE subtracts 1 from the DRX-inactivity timer for BWP1. When the DRX-inactivity timer for BWP1 expires (times out) and while the Onduration timer for BWP1 is not operating, the UE enters DRX off corresponding to BWP1, and does not detect BWP1 at this time.

[0075] For BWP2, the UE detects BWP2 while the Onduration timer for BWP2 is operating, and does not detect BWP2 while DRX off. If BWP2 is detected, the UE starts or restarts the DRX-inactivity timer for BWP2. If another BWP (a BWP other than BWP2) is detected, the UE does not start or restart the DRX-inactivity timer for BWP2, and if BWP2 is not detected in the slot (i.e., the target time unit), the UE subtracts 1 from the DRX-inactivity timer for BWP2. When the DRX-inactivity timer for BWP2 expires (times out) and while the Onduration timer for BWP2 is not operating, the UE enters DRX off corresponding to BWP2, and does not detect BWP2 at this time.

[0076] In example 11, the CDRX parameters DRX-inactivity timer and onduration timer have their own parameters for different BWPs, for example, the first object and the second object are BWP1 and BWP2, and there is only one Onduration timer, and the details are as follows: (1)DRX-inactivitytimer for BWP1. (2)DRX-inactivitytimer for BWP2. (3) Other CDRX parameters are the same as those of R15 and R16.

[0077] For BWP1, the UE detects PDCCH BWP1 within the Onduration timer. If BWP1 is detected, the UE starts or restarts the DRX-inactivity timer for BWP1. If another DCI format (a BWP other than BWP1) is detected, the DRX-inactivity timer for BWP1 is not started or restarted, and if BWP1 is not detected in the slot, the DRX-inactivity timer is subtracted by 1. When the DRX-inactivity timer for BWP1 expires (times out) and the Onduration timer is not running, the UE enters DRX off corresponding to BWP1 and does not detect BWP1 at this time.

[0078] For BWP2, the UE detects PDCCH BWP2 within the Onduration timer. If BWP2 is detected, the UE starts or restarts the DRX-inactivity timer for BWP2. If another DCI format (a BWP other than BWP2) is detected, the DRX-inactivity timer for BWP2 is not started or restarted, and if BWP2 is not detected in the slot, the DRX-inactivity timer is subtracted by 1. When the DRX-inactivity timer for BWP2 expires (times out) and the Onduration timer is not running, the UE enters DRX off corresponding to BWP2 and does not detect BWP2 at this time.

[0079] In example 12, the CDRX parameters DRX-inactivity timer and onduration timer have their own parameters for different BWPs, for example, the first object and the second object are BWP1 and BWP2, and there is only one DRX-inactivity timer, and the details are as follows: (1) Onduration timer for BWP1. (2) Onduration timer for BWP2. (3) Other CDRX parameters are the same as those of R15 and R16.

[0080] The UE detects BWP1 within the Onduration timer for BWP1, and detects BWP2 within the Onduration timer for BWP2. If it detects BWP1 or BWP2, it starts or restarts the DRX-inactivity timer. When the DRX-inactivity timer expires and the Onduration timer for BWP1 is not operating, the UE enters DRX off corresponding to BWP1 and does not detect BWP1 at this time. When the DRX-inactivity timer expires and the Onduration timer for BWP2 is not operating, the UE enters DRX off corresponding to BWP2 and does not detect BWP2 at this time.

[0081] The relevant flows of parameters corresponding to objects such as the RNTI set, SS set, and CORESET set are similar to those of the DCI format, DCI format set having a certain DCI size, UL grant set, DL grant set, BWP set, etc. in the different examples above, and therefore will not be described here.

[0082] In summary, in an embodiment of the present application, by setting different CDRX parameters, such as different DRX-inactivity timer and onduration timer, for different DCI formats (or other objects), the UE can intercept different DCI formats in different interception modes (e.g., DRX-inactivity timer mechanisms with different parameter values), thereby avoiding unnecessary blind detection of PDCCH and saving power, especially when the DCI sizes of different DCI formats are different.

[0083] Optionally, in the physical downlink control channel interception method of the embodiment of the present application, when a CDRX on-duration timer corresponding to the first object is not operating and a CDRX inactivity timer corresponding to the first object times out, the terminal device may determine that it enters a DRX inactivity period corresponding to the first object.

[0084] Optionally, in the physical downlink control channel interception method of the embodiment of the present application, the method may further include determining that the terminal device enters a DRX active period when a CDRX on-duration timer or a CDRX inactivity timer corresponding to any one of the target objects is activated.

[0085] Optionally, in the physical downlink control channel interception method of the embodiment of the present application, before step 203, the terminal equipment may further include receiving a wake-up signal (WUS), and the wake-up signal is used to indicate one of the following:

[0086] (1) The wake-up signal is used for instructing whether to intercept PDCCH during the operation of all CDRX on-duration timers corresponding to the plurality of sets of CDRX parameters, and is associated with the plurality of sets of CDRX parameters, i.e., the wake-up signal can simultaneously instruct intercepting actions of PDCCHs associated with a plurality of target objects having corresponding relationships with the plurality of sets of CDRX parameters.

[0087] In one example, the WUS indicates whether the UE detects or does not detect the PDCCH within the activation times of all onduratontimers (e.g., onduratontimer for DCI format 0_1 ​​and onduratontimer for DCI format 1_1).

[0088] (2) The wake-up signal is used for instructing whether to intercept a PDCCH during the operation of a CDRX on-duration timer corresponding to a first set of CDRX parameters among the sets of CDRX parameters, and is associated with the first set of CDRX parameters, i.e., the wake-up signal can instruct an intercept action of a PDCCH associated with a specific one of a plurality of target objects having a corresponding relationship with the sets of CDRX parameters.

[0089] In one example, the WUS indicates whether the UE detects or does not detect the PDCCH during the operation of different onduratontimers (e.g., onduratontimer for DCI format 0_1 ​​and onduratontimer for DCI format 1_1), respectively. For example, the DCI of the WUS includes at least two bits that respectively indicate whether the UE detects or does not detect the PDCCH during the operation of the onduratontimer for DCI format 0_1 ​​and onduratontimer for DCI format 1_1.

[0090] Optionally, in the method for intercepting a physical downlink control channel of the embodiment of the present application, when a first trigger condition is satisfied, the terminal device switches from a first search space group corresponding to a first object to a second search space group corresponding to the first object, the multiple target objects have a corresponding relationship with at least two search space groups, and the terminal device intercepts a first PDCCH associated with the first object based on the second search space group.

[0091] In the embodiment of the present application, at least two different search space groups are set for any one of the different objects, for example, at least a first search space group and a second search space group may be set for a first object of a plurality of target objects, and the plurality of target objects may be different objects belonging to the same type or different objects belonging to different types, whereby, when a further preset condition, i.e., a first trigger condition, is satisfied, the interception of the associated first PDCCH based on the first search space group corresponding to the first object can be switched to the interception of the associated first PDCCH based on the second search space group corresponding to the first object. In this way, the PDCCH associated with the different objects can be intercepted based on the setting of at least two different search space groups respectively corresponding to the different objects, which avoids unnecessary blind detection of PDCCH, avoids waste of power of the terminal device, and saves power consumption of the terminal.

[0092] Optionally, in the physical downlink control channel interception method of the embodiment of the present application, the first trigger condition includes one of the following:

[0093] (1) The first PDCCH is received. When the first PDCCH is received, the search space group corresponding to the first object is switched. This method can be understood as: the reception of the first PDCCH implicitly triggers the switching of the search space group corresponding to the first object.

[0094] (2) A target PDCCH is received, and a bit is carried in the DCI of the target PDCCH, which indicates that the terminal device switches from the first search space group to the second search space group. When the terminal device receives a target PDCCH carrying a DCI instructing to switch a search space group corresponding to a first object, this method of switching a search space group corresponding to a first object can be understood as explicitly triggering the search space group corresponding to the first object by the DCI carried in the target PDCCH.

[0095] (3) The first timer times out. The first timer is started after the first search space group becomes effective, is restarted when the first PDCCH is received, and continues to operate when the first PDCCH is not received.

[0096] The following description takes as an example a case where the terminal device UE holds the following parameters: The first object is DCI format 0_1, the corresponding first search space group is SS group 1, and the second search space group is SS group 2. The second object is DCI format 1_1, the corresponding first search space group is SS group 1, and the second search space group is SS group 2. Then, the trigger conditions for switching between different SS groups may be as follows:

[0097] In one example, when the UE receives a specific DCI format(s) such as DCI format 0_1, the UE switches from SS group 1 for DCI format 0_1 ​​to SS group 2 for DCI format 0_1 ​​(i.e., at this time, the SS group1 may be deactivated and the SS group2 may be activated), and SS group 1 for DCI format 0_1 ​​and SS group 2 for DCI format 0_1 ​​may be preset by a network side device (e.g., a base station). When the UE receives a specific DCI format(s) such as DCI format 1_1, the UE switches from SS group 1 for DCI format 1_1 to SS group 2 for DCI format 1_1 (i.e., at this time, the SS group 1 may be deactivated and the SS group2 may be activated), and SS group 1 for DCI format 1_1 and SS group 2 for DCI format 1_1 may be preset by a network side device (e.g., a base station).

[0098] In another example, after switching to SS group 2 for DCI format 0_1, the UE starts timer 1 and counts down. If a DCI format of a specific format such as DCI format 0_1 ​​is not received, the UE makes timer 1 count once (subtract 1 from timer 1), if a DCI format of a specific format such as DCI format 0_1 ​​is received, the UE restarts timer 1, and if timer 1 expires, the UE switches to SS group 1 for DCI format 0_1. After switching to SS group 2 for DCI format 1_1, the UE starts timer 2 and counts down. If a DCI format of a specific format such as DCI format 1_1 is not received, the UE makes timer 2 count once (subtract 1 from timer 2), if a DCI format of a specific format such as DCI format 1_1 is received, the UE restarts timer 2, and if timer 2 expires, the UE switches to SS group 1 for DCI format 1_1.

[0099] Optionally, in the method for intercepting a physical downlink control channel according to the embodiment of the present application, The method may further include the terminal device stopping intercepting the first PDCCH based on the first search space group when the first trigger condition is satisfied, i.e., not intercepting the first PDCCH based on the first search space group corresponding to the first object when the first trigger condition is satisfied.

[0100] Referring to FIG. 3, an embodiment of the present application provides a method for intercepting a physical downlink control channel performed by a terminal device, where the terminal device includes a UE of R17 version or later, and the method includes the following steps:

[0101] Step 301: If a first trigger condition is met, the terminal device switches from a first search space group corresponding to a first object to a second search space group corresponding to the first object, the first object is one of a plurality of target objects, and the plurality of target objects have a corresponding relationship with at least two search space groups.

[0102] Optionally, the plurality of target objects having a corresponding relationship with at least two search space groups may be understood to mean that each of the plurality of target objects has a corresponding relationship with at least two search space groups.

[0103] Step 303: The terminal device listens to a first PDCCH associated with a first object based on the second search space group.

[0104] The plurality of target objects includes at least one of the following:

[0105] (1) Downlink control information DCI format. Optionally, the DCI format belongs to a corresponding DCI set, where the DCI set includes at least one DCI format.

[0106] (2) Uplink Grant. Optionally, the uplink grant belongs to a corresponding uplink grant set, where the uplink grant set includes at least one uplink grant. Further, optionally, the DCI format corresponding to the uplink grant includes, but is not limited to, at least one of DCI format 0_1, DCI format 0_2, and DCI format 0_0.

[0107] (3) Downlink grant. Optionally, the downlink grant belongs to a corresponding downlink grant set, where the downlink grant set includes at least one downlink grant. Further, optionally, the DCI format corresponding to the downlink grant includes at least one of DCI format 1_1, DCI format 1_2, and DCI format 1_0.

[0108] (4) A DCI format having a predetermined DCI size. Optionally, the DCI format having the predetermined DCI size belongs to a DCI format set having a corresponding predetermined DCI size, and the DCI format set having the predetermined DCI size includes at least one DCI format.

[0109] (5) Radio Network Temporary Identifier RNTI. Optionally, the RNTI belongs to a corresponding RNTI set, which includes at least one RNTI, such as a cell RNTI, a configuration scheduling RNTI, a paging RNTI, a random access RNTI, a temporary cell RNTI, a transmission interruption RNTI, a slot format indication RNTI, a PUSCH transmit power control RNTI, a semi-persistent RNTI, etc.

[0110] (6) Search Space SS. Optionally, the SS belongs to a corresponding SS set, where the SS set includes at least one SS.

[0111] (7) Control resource set CORESET. Optionally, the CORESET belongs to a corresponding CORESET set, which includes at least one CORESET, such as CORESET#0.

[0112] (8) Bandwidth portion BWP. Optionally, the BWP belongs to a corresponding BWP set, where the BWP set includes at least one BWP.

[0113] Optionally, in the physical downlink control channel interception method of the embodiment of the present application, the first object includes two or more of the above (1) to (8).

[0114] In addition, in the terminal device, at least two CDRX processes are configured for at least two (sets) of DCI formats (S), and at least one parameter value is different in the two CDRX processes; at least two CDRX processes are configured for at least two (sets) of RNTI (S), and at least one parameter value is different in the two CDRX processes; at least two CDRX processes are configured for at least two (sets) of search spaces (S), and at least one parameter value is different in the two CDRX processes; at least two CDRX processes are configured for at least two (sets) of CORESET (S), and at least one parameter value is different in the two CDRX processes; and at least two CDRX processes are configured for at least two (sets) of BWP (S), and at least one parameter value is different in the two CDRX processes.

[0115] In the embodiment of the present application, at least two different search space groups are set for any one of the different objects, for example, at least a first search space group and a second search space group may be set for a first object of a plurality of target objects, and the plurality of target objects may be different objects belonging to the same type or different objects belonging to different types, whereby, when a further preset condition, i.e., a first trigger condition, is satisfied, the interception of the associated first PDCCH based on the first search space group corresponding to the first object can be switched to the interception of the associated first PDCCH based on the second search space group corresponding to the first object. In this way, the PDCCH associated with the different objects can be intercepted based on the setting of at least two different search space groups respectively corresponding to the different objects, which avoids unnecessary blind detection of PDCCH, avoids waste of power of the terminal device, and saves power consumption of the terminal.

[0116] Optionally, in the method for intercepting a physical downlink control channel in the embodiment of the present application, the first triggering condition includes one of the following: (1) The first PDCCH is received. When the first PDCCH is received, the method of switching the search space group corresponding to the first object can be understood as implicitly triggering the switching of the search space group corresponding to the first object by receiving the first PDCCH.

[0117] (2) A target PDCCH is received, and a bit is carried in the DCI of the target PDCCH, which indicates that the terminal device switches from the first search space group to the second search space group. When the terminal device receives a target PDCCH carrying a DCI instructing to switch a search space group corresponding to a first object, this method of switching a search space group corresponding to a first object can be understood as explicitly triggering the search space group corresponding to the first object by the DCI carried in the target PDCCH.

[0118] (3) The first timer times out. The first timer is started after the first search space group becomes effective, is restarted when the first PDCCH is received, and continues to operate when the first PDCCH is not received.

[0119] The following description takes as an example a case where the terminal device UE holds the following parameters: The first object is DCI format 0_1, the corresponding first search space group is SS group 1, and the second search space group is SS group 2. The second object is DCI format 1_1, the corresponding first search space group is SS group 1, and the second search space group is SS group 2. Then, the trigger conditions for switching between different SS groups may be as follows:

[0120] In one example, when the UE receives a specific DCI format(s) such as DCI format 0_1, the UE switches from SS group 1 for DCI format 0_1 ​​to SS group 2 for DCI format 0_1 ​​(i.e., at this time, the SS group1 may be deactivated and the SS group2 may be activated), and SS group 1 for DCI format 0_1 ​​and SS group 2 for DCI format 0_1 ​​may be preset by a network side device (e.g., a base station). When the UE receives a specific DCI format(s) such as DCI format 1_1, the UE switches from SS group 1 for DCI format 1_1 to SS group 2 for DCI format 1_1 (i.e., at this time, the SS group 1 may be deactivated and the SS group2 may be activated), and SS group 1 for DCI format 1_1 and SS group 2 for DCI format 1_1 may be preset by a network side device (e.g., a base station).

[0121] In another example, after switching to SS group 2 for DCI format 0_1, the UE starts timer 1 and counts down. If a DCI format of a specific format such as DCI format 0_1 ​​is not received, the UE makes the timer count once (subtracts 1 from timer 1), if a DCI format of a specific format such as DCI format 0_1 ​​is received, the UE restarts timer 1, and if timer 1 expires, the UE switches to SS group 1 for DCI format 0_1. After switching to SS group 2 for DCI format 1_1, the UE starts timer 2 and counts down. If a DCI format of a specific format such as DCI format 1_1 is not received, the UE makes timer 2 count once (subtracts 1 from timer 2), if a DCI format of a specific format such as DCI format 1_1 is received, the UE restarts timer 2, and if timer 2 expires, the UE switches to SS group 1 for DCI format 1_1.

[0122] Optionally, the method for intercepting a physical downlink control channel in the embodiment of the present application may further include: when the first trigger condition is satisfied, the terminal device stops intercepting the first PDCCH based on the first search space group corresponding to the first object, i.e., when the first trigger condition is satisfied, the terminal device does not intercept the first PDCCH based on the first search space group corresponding to the first object.

[0123] In addition, the physical downlink control channel interception method performed by the terminal device provided in the embodiment of the present application may be performed by a physical downlink control channel interception device or a control module for performing the physical downlink control channel interception method in the physical downlink control channel interception device. In the embodiment of the present application, the physical downlink control channel interception device provided in the embodiment of the present application will be described by taking as an example a case where the physical downlink control channel interception method is performed by the physical downlink control channel interception device.

[0124] Referring to FIG. 4, an embodiment of the present application provides a physical downlink control channel interception device 400 applied to a terminal device, which includes a receiving module 401 and a processing module 403.
