Please refer to FIG. 2. FIG. 2 is a schematic flowchart of a DRX operation method provided by an embodiment of the application. The method includes the following steps:

Step 201: The UE monitors the WUS on the PDCCH during the Wake-up Signal (WUS) transmission period (occasion), the WUS occasion is located before its subsequent DRX on duration, and the WUS is used to indicate During the first time period following WUS occurrence, DRX-on duration Timer is activated or not activated.

Among them, the DRX-on duration Timer is started periodically. During the DRX-on duration Timer is running, the UE is in the active period, and the UE can monitor and receive the scheduling signaling (such as PDCCH) from the network device to perform the business normally Data sending and receiving.

Among them, the WUS occasion and the first duration are configured by the network device for the UE.

Among them, the first duration of the UE to start or not start DRX-on duration Timer indicated by WUS can be expressed by absolute duration (e.g. expressed by absolute duration in ms, etc.), or expressed by multiples of DRX cycle ( Such as expressing by 4 cycles etc.).

Step 202: If the WUS is monitored, the UE starts or does not start the DRX-on duration Timer within the first time period following the WUS occasion.

Specifically, if the UE detects the WUS, the UE activates or does not activate the DRX-on duration Timer based on the monitored WUS within the first time period following the WUS occasion. If the WUS is used to indicate that the DRX-on duration Timer is not to be started during the first time period following the WUS occasion, then the UE is not to start the DRX during the first time period subsequent to the WUS occasion -on duration Timer; if the WUS is used to instruct to start DRX-on duration Timer within the first time period following the WUS occasion, then the UE starts within the first time period following the WUS occasion The DRX-on duration Timer.

Please refer to FIG. 3A. FIG. 3A is a schematic flowchart of another DRX operation method provided by an embodiment of the application. The method includes the following steps:

Step 301: The UE monitors the WUS on the PDCCH in the WUS occasion, and the WUS occasion is located before its subsequent DRX on duration, and the WUS is used to indicate that DRX is not to be started during the first time period after the WUS occasion. on duration Timer.

Step 302: If the WUS is monitored, the UE does not start the DRX-on duration Timer within the first time period following the WUS occasion.

Step 303: 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:

Receive RRC configuration information from a network device, the RRC configuration information includes DRX related parameter configuration and WUS occasion configuration, the DRX related parameter configuration includes DRX cycle and DRX-on duration Timer, and the WUS occasion configuration includes WUS occasion period and WUS Time Offset, the WUS Time Offset is the time advance offset from the start time of WUS occasion to the start time of DRX on duration (as shown in Figure 3B), and the WUS occasion period is the DRX cycle Integer multiples.

Among them, DRX cycle has long DRX cycle and short DRX cycle, and network devices can configure a WUS occasion cycle for long DRX cycle and short DRX cycle respectively (that is, configure a value that is an integer multiple of DRX cycle). When the UE switches from the long DRX cycle to the short DRX cycle, the UE restarts the WUS occasion period under the short DRX cycle. When the UE switches from the short DRX cycle to the long DRX cycle, the UE restarts the WUS occasion cycle under the long DRX cycle.

In an implementation manner of the present application, before each WUS occasion arrives, the method further includes:

The UE determines whether it needs to monitor WUS in the upcoming WUS occasion;

If it is determined that it is necessary to monitor the WUS in the upcoming WUS occasion, the UE monitors the WUS in the upcoming WUS occasion.

Further, under the fifth condition and the sixth condition, it is determined that WUS needs to be monitored in the upcoming WUS occasion; the fifth condition includes that the WUS indicates that the first duration of the DRX-on duration Timer is to pass the absolute duration Or, the first duration of the WUS instructing not to start DRX-on duration Timer is expressed by a multiple of DRX cycle, and the current DRX cycle of the UE is the first DRX cycle or the current DRX cycle of the UE The cycle duration is the same as that of the previous DRX cycle; the sixth condition includes that the UE has not received WUS; or the time for not starting DRX-on duration Timer indicated by the WUS last received by the UE ends at the current Before the DRX on duration start time; or, the time for not starting DRX-on Duration Timer indicated by WUS last time received by the UE does not include the current DRX on duration start time.

Further, under the seventh condition, it is determined that WUS needs to be monitored in the upcoming WUS occasion, and the seventh condition includes that the WUS indicates that the first duration of DRX-on duration Timer not to start is expressed by a multiple of DRX cycle And the duration of the current DRX cycle of the UE is different from the duration of the previous DRX cycle.

For example, WUS is used to instruct the UE not to start DRX-on duration Timer for a subsequent period of time. The information that the UE receives the network RRC configuration includes: DRX related parameter configuration (such as DRX cycle (including long DRX cycle and short DRX cycle) , DRX-on duration Timer, etc.) and WUS occasion configuration (such as WUS occasion and DRX on duration one-to-one correspondence (that is, WUS cycle is equal to DRX cycle), and WUS occasion starts from WUS Time Offset before DRX on duration). As shown in Figure 3C, the UE does not receive WUS in the first WUS occasion, so the UE starts DRX-on duration Timer in the first DRX cycle. The UE receives WUS in the second WUS occasion. The WUS indicates that the duration of the UE sleep is 4 cycles, and the UE is short DRX cycle from the second DRX cycle to the fourth DRX cycle. Therefore, the UE is in the second DRX cycle. Cycle, the third DRX cycle and the fourth DRX cycle do not start the DRX-on duration Timer, and the UE does not need to monitor WUS again in the third WUS occasion and the fourth WUS occasion. The UE switches from short DRX cycle to long DRX cycle in the 5th DRX cycle, so the UE needs to monitor WUS in the 5th WUS occasion. The UE receives WUS in the fifth WUS occasion, and the WUS indicates that the duration of the UE sleep is 1 cycle, so the UE does not start the DRX-on duration Timer in the fifth DRX cycle. The UE does not receive UWS in the sixth WUS occasion and the seventh WUS occasion, so the UE starts DRX-on duration Timer in both the sixth DRX cycle and the seventh DRX cycle.

It can be seen that, in the embodiment of this application, if the network device predicts that the UE will not be scheduled for a period of time, the network device sends WUS to the UE before DRX on duration, indicating that the UE is in this period of time (may be 1 One or more DRX cycles do not start the DRX-on duration Timer, so that the UE stays in a sleep state during this period of time, thereby reducing device power consumption. If the UE does not receive WUS, whether it is because the network device does not send WUS to the UE or the network device sends WUS to the UE and the UE does not detect WUS, the UE normally starts DRX-on duration Timer. In this way, the UE misses WUS detection Some power saving gain will be lost, but it will not affect the UE's reception of the PDCCH/PDSCH scheduled by the network, and it will not affect the link performance.

Please refer to FIG. 4A. FIG. 4A is a schematic flowchart of another DRX operation method provided by an embodiment of the application. The method includes the following steps:

Step 402: If the WUS is monitored, the UE starts the DRX-on duration Timer within the first time period following the WUS occasion.

Step 403: If the WUS cannot be monitored and the first indication information indicates that the UE does not start DRX-on duration Timer to monitor the PDCCH during sleep, the UE does not start the DRX -on duration Timer, the first indication information comes from a network device.

Step 404: If the WUS cannot be monitored and the first indication information indicates that the UE starts the DRX-on duration Timer to monitor the PDCCH at intervals during the continuous sleep period, then the UE is at the start time of the DRX on duration Before, it is determined whether to start the DRX-on duration Timer.

Step 405: If it is determined to start the DRX-on duration Timer, the UE starts the DRX-on duration Timer at the start time of the DRX-on duration.

Step 406: If it is determined not to start the DRX-on duration Timer, the UE does not start the DRX-on duration Timer at the start moment of the DRX-on duration.

The first counter is used to record the number of times that the UE has not started the DRX-on duration Timer continuously. The initial value of the first counter is 0.

Wherein, the first timer is used to record the time when the UE has not started the DRX-on duration Timer continuously.

The first threshold and the second threshold may be configured by the network device for the UE through RRC signaling.

The UE determines whether it needs to monitor WUS in the upcoming WUS occasion;

If it is determined that it is necessary to monitor WUS in the upcoming WUS occasion, the UE monitors the WUS in the upcoming WUS occasion.

Further, under the eighth condition and the ninth condition, it is determined that WUS needs to be monitored in the upcoming WUS occasion;

The eighth condition includes that the first duration of the WUS instruction to start DRX-on duration Timer is expressed by absolute duration; or, the first duration of the WUS instruction to start DRX-on duration Timer is expressed by a multiple of DRX cycle , 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 previous DRX cycle;

Further, under the tenth condition, it is determined that WUS needs to be monitored in the upcoming WUS occasion, where the tenth condition includes that the first duration of the WUS instructing to start DRX-on duration Timer is expressed by a multiple of DRX cycle, And the duration of the current DRX cycle of the UE is different from the duration of the previous DRX cycle.

For example, WUS is used to instruct the UE to normally start DRX-on duration Timer in the following period of time, and the network does not allow the UE to start DRX-on duration Timer at intervals during the continuous sleep period. The information that UE receives the network RRC configuration includes: DRX related parameter configuration (such as DRX cycle (including long DRX cycle and short DRX cycle), DRX-on duration Timer, etc.) and WUS occasion configuration (such as WUS occasion and DRX on duration one-to-one correspondence (That is, the WUS cycle is equal to the DRX cycle), and the WUS occasion starts at the WUS Time Offset before the DRX on duration). As shown in Figure 4B, the UE does not receive WUS in the first WUS occasion, so the UE does not start DRX-on duration Timer in the first DRX cycle. The UE receives WUS in the second WUS occasion. The WUS indicates that the duration of the UE wake-up is 4 cycles, and the UE is short DRX cycle from the second DRX cycle to the fourth DRX cycle, so the UE is in the second DRX cycle. DRX cycle, the third DRX cycle and the fourth DRX cycle all start the DRX-on duration Timer normally, and the UE does not need to monitor WUS again in the third WUS occasion and the fourth WUS occasion. The UE switches from short DRX cycle to long DRX cycle in the 5th DRX cycle, so the UE needs to monitor WUS in the 5th WUS occasion. The UE receives the WUS in the fifth WUS occasion, and the WUS indicates that the duration of the UE wakeup is 1 cycle, so the UE normally starts the DRX-on duration Timer in the fifth DRX cycle. The UE does not receive WUS in the sixth WUS occasion, so the UE does not start DRX-on duration Timer in the sixth DRX cycle. The UE receives the WUS in the seventh WUS occasion, and the WUS indicates that the UE wake-up duration is 1 cycle, so the UE starts the DRX-on duration Timer in the seventh DRX cycle.

For another example, WUS is used to instruct the UE to start the DRX-on duration Timer normally in the subsequent period of time, and the network allows the UE to start the DRX-on duration Timer at intervals during the continuous sleep period. The information that the UE receives the network RRC configuration includes: DRX related parameter configuration (such as DRX cycle (including long DRX cycle and short DRX cycle), DRX-on duration Timer, etc.), WUS occasion configuration (such as WUS occasion and DRX on duration one-to-one correspondence (That is, the WUS cycle is equal to the DRX cycle), and the WUS occasion starts at the WUS Time Offset before the DRX on duration and the maximum time that the UE is allowed to continue to sleep: second threshold = 2DRX cycle. Initialize the first state variable, that is, the value of the first state variable = the fourth threshold.

The UE does not receive WUS in the first WUS occasion, so the UE does not start DRX-on duration Timer in the first DRX cycle. At the same time, the UE starts the first timer at the beginning of the first DRX on duration. The UE receives WUS in the second WUS occasion. The WUS indicates that the UE wakes up for 3 cycles, and the UE is short DRX cycle from the second DRX cycle to the fourth DRX cycle. Therefore, the UE is in the second DRX cycle. cycle, the third DRX cycle and the fourth DRX cycle both start the DRX-on duration Timer normally, and the UE does not need to monitor WUS any more in the third WUS occasion and the fourth WUS occasion. At the same time, the UE stops the first timer at the start of the second DRX on duration. The UE does not receive WUS for 3 consecutive WUS occasions starting from the fifth WUS occasion, so the UE does not start DRX-on duration Timer in the fifth DRX cycle and the sixth DRX cycle. At the same time, the UE starts the first timer at the beginning of the fifth DRX on duration. At the start of the seventh DRX on duration, the UE judges that the first timer has expired, so the UE starts the DRX-on duration Timer in 7 DRX cycles. At the same time, the UE stops the first timer at the start of the seventh DRX on duration, and sets the value of the first state variable to the third threshold. At the beginning of the 8th DRX on duration, the UE judges whether to start DRX-on in the 8th DRX cycle according to the situation of receiving WUS in the 8th WUS occasion and combining with the situation of receiving PDCCH during the 7th DRX cycle. Duration Timer, there are 3 possible situations:

1) As shown in Figure 4C, the UE receives WUS at the 8th WUS occasion. The WUS indicates that the UE wakes up for 2 cycles. Therefore, the UE normally starts DRX on the 8th DRX cycle and the 9th DRX cycle. on duration Timer, and the UE does not need to monitor wake up signal in the 9th WUS occasion. At the same time, the UE sets the value of the first state variable to the fourth threshold at the beginning of the eighth DRX on duration.

2) As shown in Figure 4D, the UE has not received WUS in the 8th WUS occasion, and the UE has not received the PDCCH used to instruct the UE to schedule uplink or downlink transmission during the 7th DRX cycle. 8 DRX cycles do not start DRX-on duration Timer. At the same time, the UE starts the first timer at the beginning of the eighth DRX on duration, and sets the value of the first state variable to the fourth threshold. Subsequently, the UE still does not receive WUS in the 9th WUS occasion, so the UE does not start DRX-on duration Timer in the 9th DRX cycle.

3) As shown in Figure 4E, the UE still does not receive WUS in the 8th WUS occasion, and the UE receives the PDCCH used to instruct the UE to schedule uplink or downlink transmission during the 7th DRX cycle. Therefore, the UE is in the 8th DRX cycle. Each DRX cycle continues to start DRX-on duration Timer normally. Subsequently, the UE still did not receive WUS in the 9th WUS occasion, and the UE did not receive the PDCCH used to instruct the UE to schedule uplink or downlink transmission during the 8th DRX cycle, so the UE did not start in the 9th DRX cycle DRX-on duration Timer. At the same time, the UE starts the first timer at the beginning of the 9th DRX on duration, and sets the value of the first state variable to the fourth threshold.

It can be seen that in the embodiment of this application, if the network device predicts that the UE will be scheduled in a subsequent period of time, the network device sends WUS to the UE before DRX ON duration, indicating that the UE is in this period of time (may be 1 or Multiple DRX cycles all start DRX-on duration Timer normally.
