Referring to fig. 2, fig. 2 is a flowchart illustrating a DRX operation method according to an embodiment of the present disclosure, where the method includes the following steps:
step 201: the UE monitors a WUS on a PDCCH within a Wake-up Signal (WUS) transmission period (event), the WUS event is located before a subsequent DRX on duration, and the WUS is used for indicating that a DRX-on duration Timer is started or not started within a first time duration subsequent to the WUS event.
The DRX-on duration Timer is periodically started to operate, and during the DRX-on duration Timer operation period, the UE is in an active period, and the UE may monitor and receive a scheduling signaling (such as a PDCCH) from a network device, thereby performing normal service data transceiving.
The WUS occasion and the first duration are configured for the UE by the network equipment.
The first duration of the UE activation or deactivation of the DRX-on duration Timer indicated by the WUS may be expressed by an absolute duration (e.g., expressed by an absolute duration in ms, etc.), or may be expressed by a multiple of a DRX cycle (e.g., expressed by 4 cycles, etc.).
Step 202: and if the WUS is monitored, the UE starts or does not start the DRX-on duration Timer in a first time length subsequent to the WUS occase.
Specifically, if the UE monitors the WUS, the UE starts or does not start the DRX-on duration Timer based on the monitored WUS within a first time duration subsequent to the WUS occasion. If the WUS is used for indicating that the DRX-on duration Timer is not started in the first time length after the WUS event, the UE does not start the DRX-on duration Timer in the first time length after the WUS event; and if the WUS is used for indicating that the DRX-on duration Timer is started in the first time length after the WUS event, the UE starts the DRX-on duration Timer in the first time length after the WUS event.
It can be seen that, in the embodiment of the present application, the UE monitors the WUS on the PDCCH in the WUS occasion, the WUS occasion is located before the subsequent DRX on duration, the WUS is configured to instruct to start or not start the DRX-on duration Timer in the first duration subsequent to the WUS occasion, and if the UE monitors the WUS, the UE starts or does not start the DRX-on duration Timer based on the WUS, so that the DRX-on duration Timer is started when needed, and further, the power consumption of the device is reduced.
Referring to fig. 3A, fig. 3A is a schematic flowchart of another DRX operation method according to an embodiment of the present disclosure, where the method includes the following steps:
step 301: the UE monitors the WUS on the PDCCH in the WUS event, the WUS event is positioned before the subsequent DRX on duration, and the WUS is used for indicating that the DRX-on duration Timer is not started in the first time duration subsequent to the WUS event.
Step 302: and if the WUS is monitored, the UE does not start the DRX-on duration Timer in a first time length subsequent to the WUS occase.
Step 303: and if the WUS cannot be monitored, the UE starts the DRX-on duration Timer.
In an implementation manner of the present application, before step 301, the method further includes:
receiving RRC configuration information from a network device, wherein the RRC configuration information comprises DRX-related parameter configuration and WUS event configuration, the DRX-related parameter configuration comprises a DRX cycle and a DRX-on duration Timer, the WUS event configuration comprises a WUS event period and a WUS Time Offset (Time Offset), the WUS Time Offset is a Time advance Offset from a WUS event starting Time to a DRX-on duration starting Time (shown in figure 3B), and the WUS event period is integral multiple of the DRX cycle.
The DRX cycle includes a long DRX cycle and a short DRX cycle, and the network device may configure one WUS event cycle for each of the long DRX cycle and the short DRX cycle (i.e., configure a value that is an integer multiple of the DRX cycle). When the UE is switched from the long DRX cycle to the short DRX cycle, the UE restarts the WUS occase cycle under the short DRX cycle. When the UE is switched from the short DRX cycle to the long DRX cycle, the UE restarts the WUS occase cycle under the long DRX cycle.
In one implementation of the present application, before each WUS occase arrives, the method further includes:
the UE determines whether WUS monitoring is required within an upcoming WUS occast;
if it is determined that WUS monitoring is required within the upcoming WUS occase, the UE monitors the WUS within the upcoming WUS occase.
Further, under fifth and sixth conditions, determining that a WUS needs to be listened for within an upcoming WUS occase; the fifth condition includes the WUS indicating that a first duration of not starting a DRX-on duration Timer is expressed in absolute duration; or the WUS indicates that a first duration of a non-starting DRX-on duration Timer is expressed by a multiple of a DRX cycle, and the current DRX cycle of the UE is the first DRX cycle or the current DRX cycle of the UE is the same as the duration of the last DRX cycle; the sixth condition includes the UE not receiving a WUS; or the time that the UE does not start the DRX-on duration Timer indicated by the WUS received last time is before the current DRX-on duration starting time; or the time for not starting the DRX-on Duration Timer indicated by the WUS received last time by the UE does not include the current DRX-on Duration starting time.
Further, a need to monitor WUS within an upcoming WUS occasion is determined under a seventh condition that includes the WUS indicating a first duration of not starting a DRX-on duration Timer is expressed by a multiple of a DRX cycle, and a current DRX cycle of the UE is different in duration from a previous DRX cycle.
For example, the WUS is used to instruct the UE not to start the DRX-on duration Timer for a subsequent period of time, and the UE receives the network RRC configuration information: DRX related parameter configuration (e.g., DRX cycle (including long DRX cycle and short DRX cycle), DRX-on duration Timer, etc.) and WUS event configuration (e.g., WUS event corresponds to DRX on duration one-to-one (i.e., WUS period equals DRX cycle), and WUS event starts before DRX on duration WUS Time Offset). As shown in fig. 3C, the UE does not receive a WUS at the 1 st WUS occasion, and therefore the UE starts a DRX-on duration Timer at the 1 st DRX cycle. The UE receives a WUS in the 2 nd WUS occasion, the WUS indicates that the duration of UE sleep is 4 cycles, and the UE is short DRX cycles from the 2 nd DRX cycle to the 4 th DRX cycle, so that the UE does not start a DRX-on duration Timer in the 2 nd DRX cycle, the 3 rd DRX cycle and the 4 th DRX cycle, and the UE does not need to monitor the WUS in the 3 rd WUS occasion and the 4 th WUS occasion. The UE switches from short DRX cycle to long DRX cycle in 5th DRX cycle, so the UE needs to monitor WUS in 5th WUS occase. The UE receives a WUS in the 5th WUS occasion, the WUS indicates that the duration of UE sleep is 1 cycle, so the UE does not start a DRX-on duration Timer in the 5th DRX cycle. The UE does not receive the UWS in both the 6 th WUS occasion and the 7 th WUS occasion, so the UE starts a DRX-on duration Timer in both the 6 th DRX cycle and the 7 th DRX cycle.
It can be seen that, in the embodiment of the present application, if the network device predicts that the UE will not be scheduled for a subsequent period of time, the network device sends a WUS to the UE before the DRX on duration, and instructs the UE not to start the DRX-on duration Timer for the period of time (possibly 1 or more DRX cycles), so that the UE remains in the sleep state for the period of time, thereby further reducing the power consumption of the device. If the UE does not receive the WUS, the UE normally starts a DRX-on duration Timer no matter the network equipment does not send the WUS to the UE or the network equipment sends the WUS to the UE and the UE does not detect the WUS, and in the mode, the UE fails to detect the WUS and loses some power saving gain (power saving gain), but does not influence the PDCCH/PDSCH that the UE receives network scheduling and has no influence on link performance.
Referring to fig. 4A, fig. 4A is a schematic flowchart of another DRX operation method according to an embodiment of the present disclosure, where the method includes the following steps:
step 401: the UE monitors the WUS on the PDCCH in the WUS event, the WUS event is positioned before the subsequent DRX on duration, and the WUS is used for indicating that the DRX-on duration Timer is started in the first time duration subsequent to the WUS event.
Step 402: and if the WUS is monitored, the UE starts the DRX-on duration Timer in a first time length subsequent to the WUS occase.
Step 403: if the WUS is not monitored, and first indication information indicates that the UE does not intermittently start a DRX-on duration Timer to monitor the PDCCH during a sleep period, the UE does not start the DRX-on duration Timer, and the first indication information is from network equipment.
Step 404: if the WUS is not monitored, and the first indication information indicates that the UE starts a DRX-on Timer at intervals during the continuous sleep period to monitor the PDCCH, the UE determines whether to start the DRX-on Timer before the starting time of the DRX-on.
Step 405: and if the starting of the DRX-on duration Timer is determined, the UE starts the DRX-on duration Timer at the starting time of the DRX-on duration.
Step 406: and if the DRX-on duration Timer is determined not to be started, the UE does not start the DRX-on duration Timer at the starting time of the DRX-on duration.
In an implementation manner of the present application, the UE maintains a first counter or maintains a first Timer, and the UE further maintains a first state variable, where the first state variable is used to indicate whether to wake up the UE to start a DRX-on duration Timer when the WUS is not monitored;
determining to start the DRX-on duration Timer under a first condition, where the first condition includes that a value of the first counter is equal to a first threshold, or the first Timer has timed out, a timing duration of the first Timer is a second threshold, the first threshold is a maximum consecutive number of times that the network device configures the UE to allow the UE not to start the DRX-on duration Timer, and the second threshold is a maximum time that the network device configures the UE to allow the UE not to start the DRX-on duration Timer;
the method further comprises the following steps: and when the value of the first state variable is the third threshold value, the first state variable is used for indicating that the UE is awakened to start the DRX-on Timer under the condition that the WUS is not monitored.
Wherein, the first counter is used for recording the times that the UE does not start the DRX-on duration Timer continuously. The initial value of the first counter is 0.
Wherein, the first Timer is used for recording the time that the UE does not start the DRX-on duration Timer continuously.
Wherein the first threshold and the second threshold may be configured by the network device to the UE through RRC signaling.
The third threshold may be represented by true, 1, or other values.
In an implementation manner of the present application, the DRX-on duration Timer is determined to be started under a second condition, where the second condition includes that the value of the first state variable is the third threshold, and the UE receives, in a last DRX-on duration, a PDCCH that is sent by the network device and used for scheduling the UE.
In an implementation manner of the present application, under a third condition, it is determined not to start the DRX-on duration Timer, where the third condition includes that a value of the first state variable is the third threshold, and the UE does not receive a PDCCH, which is sent by the network device and used for scheduling the UE, in a last DRX-on duration;
the method further comprises the following steps: and when the DRX-on duration Timer is not started at the starting time of the DRX-on duration, the UE sets the value of the first state variable as a fourth threshold, and when the value of the state variable is the fourth threshold, the UE is used for indicating that the UE is not awakened to start the DRX-on duration Timer under the condition that the UE cannot monitor the WUS.
The fourth threshold may be denoted by false, may be denoted by 0, or may be denoted by another value.
In an implementation manner of the present application, under a fourth condition, determining not to start the DRX-on duration Timer, the fourth condition includes:
the value of the first counter is less than the first threshold or the first timer has not timed out (i.e., has not exceeded a second threshold);
and the value of the first state variable is the fourth threshold.
In an implementation manner of the present application, the update condition of the first counter includes that the UE does not start a DRX-on Timer at a current mth DRX on start time, where m is greater than 1.
In an implementation manner of the present application, the reset condition of the first counter includes that the UE does not start the DRX-on Timer at the w-1 th DRX on duration start time, and the UE starts the DRX-on Timer at the w-1 th DRX on duration start time, where w is greater than 1.
In an implementation manner of the present application, the starting or restarting condition of the first Timer includes that the UE does not start a DRX-on Timer at a first DRX-on start time; or, the UE starts a DRX-on duration Timer at the k-1 th DRX-on duration starting time, and the UE does not start the DRX-on duration Timer at the k-1 th DRX-on duration starting time, wherein k is greater than 1.
In an implementation manner of the present application, the stop condition of the first Timer includes that the first Timer is running, and the UE starts a DRX-on duration Timer at a current h-th DRX on duration start time, where h is greater than 1.
In an implementation manner of the present application, before step 401, the method further includes:
receiving RRC configuration information from a network device, wherein the RRC configuration information comprises DRX-related parameter configuration and WUS event configuration, the DRX-related parameter configuration comprises a DRX cycle and a DRX-on duration Timer, the WUS event configuration comprises a WUS event period and a WUS Time Offset (Time Offset), the WUS Time Offset is a Time advance Offset from the WUS event starting Time to the DRX-on duration starting Time (shown in figure 3B), and the WUS event period is integral multiple of the DRX cycle.
The DRX cycle includes a long DRX cycle and a short DRX cycle, and the network device may configure one WUS event cycle for each of the long DRX cycle and the short DRX cycle (i.e., configure a value that is an integer multiple of the DRX cycle). When the UE is switched from the long DRX cycle to the short DRX cycle, the UE restarts the WUS occase cycle under the short DRX cycle. When the UE is switched from the short DRX cycle to the long DRX cycle, the UE restarts the WUS occase cycle under the long DRX cycle.
In one implementation of the present application, before each WUS occase arrives, the method further includes:
the UE determines whether WUS monitoring is required within an upcoming WUS occast;
if it is determined that WUS monitoring is required within the upcoming WUS occase, the UE monitors the WUS within the upcoming WUS occase.
Further, under an eighth condition and a ninth condition, determining that a WUS needs to be listened for within an upcoming WUS occase;
the eighth condition comprises the first duration that the WUS indicates to start the DRX-on duration Timer being expressed in absolute duration; or the WUS indicates that a first duration for starting a DRX-on duration Timer is expressed by a multiple of DRX cycles, and the current DRX cycle of the UE is the first DRX cycle or the duration of the current DRX cycle of the UE is the same as the duration of the last DRX cycle;
the ninth condition comprises the UE not receiving a WUS; or the time for starting the DRX-on Duration Timer indicated by the WUS received last time by the UE is before the current DRX-on Duration starting time; or, the time for starting the DRX-on Duration Timer indicated by the WUS received last time by the UE does not include the current DRX-on Duration start time.
Further, a need to monitor a WUS within an upcoming WUS occasion is determined under a tenth condition that includes the WUS indicating that a first duration to start a DRX-on duration Timer is expressed by a multiple of a DRX cycle, and a current DRX cycle of the UE is different in duration from a previous DRX cycle.
For example, the WUS is used to instruct the UE to normally start the DRX-on duration Timer for a subsequent period of time, while the network does not allow the UE to start the DRX-on duration Timer at intervals during a continuous sleep period. The information that the UE receives the network RRC configuration comprises the following information: DRX related parameter configuration (e.g., DRX cycle (including long DRX cycle and short DRX cycle), DRX-on duration Timer, etc.) and WUS event configuration (e.g., WUS event corresponds to DRX on duration one-to-one (i.e., WUS period equals DRX cycle), and WUS event starts before DRX on duration WUS Time Offset). As shown in fig. 4B, the UE does not receive a WUS at the 1 st WUS occasion, and therefore the UE does not start the DRX-on duration Timer at the 1 st DRX cycle. The UE receives a WUS in the 2 nd WUS occasion, the WUS indicates that the duration of the wake up of the UE is 4 cycles, and the UE is short DRX cycles from the 2 nd DRX cycle to the 4 th DRX cycle, so that the UE normally starts a DRX-on duration Timer in the 2 nd DRX cycle, the 3 rd DRX cycle and the 4 th DRX cycle, and the UE does not need to monitor the WUS in the 3 rd WUS occasion and the 4 th WUS occasion. The UE switches from short DRX cycle to long DRX cycle in 5th DRX cycle, so the UE needs to monitor WUS in 5th WUS occase. The UE receives a WUS at the 5th WUS occasion, the WUS indicates that the duration of the UE wake up is 1 cycle, so the UE normally starts a DRX-on duration Timer at the 5th DRX cycle. The UE does not receive a WUS at the 6 th WUS occasion, so the UE does not start the DRX-on duration Timer at the 6 th DRX cycle. The UE receives a WUS at the 7 th WUS occasion, the WUS indicates that the duration of the UE wake up is 1 cycle, so the UE starts a DRX-on duration Timer at the 7 th DRX cycle.
For another example, the WUS may be used to instruct the UE to start the DRX-on duration Timer normally for a subsequent period of time, while the network may allow the UE to start the DRX-on duration Timer at intervals during a continuous sleep period. The information that the UE receives the network RRC configuration comprises the following information: DRX-related parameter configuration (e.g., DRX cycle (including long DRX cycle and short DRX cycle), DRX-on duration Timer, etc.), WUS event configuration (e.g., WUS event corresponds to DRX on duration one-to-one (i.e., WUS period equals DRX cycle), and WUS event starts before DRX on duration) and maximum Time for which the UE is allowed to continue sleep: the second threshold is 2DRX cycle. The first state variable is initialized, i.e. the value of the first state variable equals the fourth threshold value.
The UE does not receive a WUS at the 1 st WUS occasion, so the UE does not start a DRX-on duration Timer at the 1 st DRX cycle. Meanwhile, the UE starts a first timer at the 1 st DRX on duration start time. The UE receives a WUS in the 2 nd WUS occast, the WUS indicates that the time length of the UE awakening is 3 cycles, and the UE is short DRX cycle from the 2 nd DRX cycle to the 4 th DRX cycle, therefore, the UE normally starts a DRX-on duration Timer in the 2 nd DRX cycle, the 3 rd DRX cycle and the 4 th DRX cycle, and the UE does not need to monitor the WUS again in the 3 rd WUS occast and the 4 th WUS occast. Meanwhile, the UE stops the first timer at the 2 nd DRX on duration start time. The UE does not receive WUS for 3 consecutive WUS ocsashes from the 5th WUS ocsase, so the UE does not start the DRX-on duration Timer at the 5th DRX cycle and the 6 th DRX cycle. Meanwhile, the UE starts a first timer at the 5th DRX on duration start time. And the UE judges that the first Timer is overtime at the starting moment of the 7 th DRX on duration, so that the UE starts a DRX-on duration Timer at 7 DRX cycles. Meanwhile, the UE stops the first timer at the 7 th DRX on duration start time, and sets the value of the first state variable to a third threshold value. At the 8 th DRX on duration start time, the UE determines whether to start the DRX-on duration Timer at the 8 th DRX cycle according to the case that the UE receives the WUS at the 8 th WUS occasion and in combination with the case that the UE receives the PDCCH during the 7 th DRX cycle, and specifically there are 3 possible cases as follows:
1) as shown in fig. 4C, the UE receives a WUS at the 8 th WUS occasion, which indicates that the UE wakes up for 2 cycles, so the UE starts the DRX-on duration Timer normally at both the 8 th DRX cycle and the 9 th DRX cycle, and the UE does not need to monitor the wake up signal again at the 9 th WUS occasion. Meanwhile, the UE sets the value of the first state variable as a fourth threshold value at the 8 th DRX on duration starting time.
2) As shown in fig. 4D, the UE still does not receive a WUS in the 8 th WUS occasion, and the UE does not receive a PDCCH indicating scheduling of uplink or downlink transmission for the UE during the 7 th DRX cycle, so the UE does not start a DRX-on duration Timer in the 8 th DRX cycle. And simultaneously, the UE starts a first timer at the 8 th DRX on duration starting time and sets the value of the first state variable as a fourth threshold value. Subsequently, the UE still does not receive a WUS at the 9 th WUS occasion, and therefore the UE does not start the DRX-on duration Timer at the 9 th DRX cycle either.
3) As shown in fig. 4E, the UE still does not receive a WUS in the 8 th WUS occasion, and the UE receives a PDCCH indicating that the UE is scheduled to transmit uplink or downlink during the 7 th DRX cycle, so the UE continues to normally start the DRX-on duration Timer in the 8 th DRX cycle. Subsequently, the UE still does not receive the WUS in the 9 th WUS occasion, and the UE does not receive the PDCCH indicating scheduling of uplink or downlink transmission for the UE during the 8 th DRX cycle, so the UE does not start the DRX-on duration Timer in the 9 th DRX cycle. Meanwhile, the UE starts a first timer at the 9 th DRX on duration start time, and sets the value of the first state variable to a fourth threshold.
It can be seen that in the embodiment of the present application, if the network device predicts that the UE will be scheduled for a subsequent period of time, the network device sends a WUS to the UE before the DRX ON duration, instructing the UE to start the DRX-ON duration Timer normally for the period of time (possibly 1 or more DRX cycles). If the UE does not receive the WUS, whether the UE starts a drx-onDuration timer or not is determined according to the actual situation, and the condition that the UE is out of chain due to the fact that the UE fails to receive a PDCCH/PDSCH scheduled by a network for a long time because the UE fails to detect the WUS can be avoided.
Referring to fig. 5, fig. 5 is a flowchart illustrating another DRX operation method according to an embodiment of the present disclosure, where the method includes the following steps:
step 501: network equipment sends RRC configuration information to UE, the RRC configuration information includes DRX related parameter configuration and WUS ocasement configuration, the DRX related parameter configuration includes DRX cycle and DRX-on duration Timer, the WUS ocasement configuration includes WUS ocasement period and WUS Time Offset, the WUS Time Offset is the Time advance Offset from WUS ocasement starting Time to DRX-on duration starting Time, and the WUS ocasement period is the integral multiple of DRX cycle.
The DRX cycle includes a long DRX cycle and a short DRX cycle, and the network device may configure one WUS event cycle for each of the long DRX cycle and the short DRX cycle (i.e., configure a value that is an integer multiple of the DRX cycle). When the UE is switched from the long DRX cycle to the short DRX cycle, the UE restarts the WUS occase cycle under the short DRX cycle. When the UE is switched from the short DRX cycle to the long DRX cycle, the UE restarts the WUS occase cycle under the long DRX cycle.
Step 502: the network device sends a WUS on the PDCCH, and the WUS is used for indicating that the DRX-on duration Timer is started or not started within a first time length after the WUS event.
The first duration of the UE activation or deactivation of the DRX-on duration Timer indicated by the WUS may be expressed by an absolute duration (e.g., expressed by an absolute duration in ms, etc.), or may be expressed by a multiple of a DRX cycle (e.g., expressed by 4 cycles, etc.).
In an implementation manner of the present application, the method further includes:
the network equipment sends first indication information to the UE, wherein the first indication information is used for indicating the UE to not start a DRX-on duration Timer at intervals during the continuous sleep period to monitor the PDCCH.
In an implementation manner of the present application, the first indication information is used to instruct the UE to start a DRX-on duration Timer at intervals during a continuous sleep period to monitor a PDCCH.
Specifically, the network device may use one bit field of the first indication information to indicate whether the UE is allowed to periodically start the DRX-on duration Timer to monitor the PDCCH during the continuous sleep period. The method specifically comprises the following steps: different values of 0 and 1 for the Bit field are used to indicate disallowance and allowance; or whether the Bit field exists or not is used for indicating that the existence indicates permission and the nonexistence indicates non-permission.
In an implementation manner of the present application, the network device configures a first threshold or a second threshold for the UE, where the first threshold is a maximum number of consecutive times that the network device configures for the UE and allows the UE not to start a DRX-on duration Timer, and the second threshold is a maximum time that the network device configures for the UE and allows the UE not to start the DRX-on duration Timer.
Wherein the first threshold and the second threshold may be configured by the network device to the UE through RRC signaling.
It can be seen that, in the embodiment of the present application, the UE may know each WUS occasion, each DRX cycle, and DRX-on Timer through RRC configuration information sent by the network device, and then monitor the WUS sent by the network device on the PDCCH in each WUS occasion, and further start or not start the DRX-on Timer based on the WUS, so that the DRX-on Timer is started when needed, and further, the power consumption of the device is reduced.
