As shown in fig. 3, this embodiment provides a method for monitoring a physical downlink control channel PDCCH, including:

step S110: receiving a bandwidth part switching command or a monitoring strategy contained in a Radio Resource Control (RRC) message;

step S120: and according to the monitoring result of the wake-up signal indicated by the monitoring strategy, monitoring the PDCCH.

The bandwidth Part (BWP) switch command is used to trigger the terminal to switch from the source bandwidth Part to the target bandwidth Part.

Switching from the source bandwidth portion to the target bandwidth portion herein comprises:

the terminal establishes connection with the base station through the source bandwidth part, and changes into: the terminal establishes connection with the base station through the target bandwidth part;

and/or the number of the groups of groups,

the terminal interacts with the base station by utilizing the source bandwidth part, and changes into: the terminal interacts with the base station through the target bandwidth portion. The content of the interactions here include: data, signals, and/or signaling, etc.

The RRC message may be any message issued by the RRC layer. In this embodiment, the RRC message may be a message related to RRC connection establishment between the terminal and the base station. For example, the RRC message may include at least one of:

an RRC connection setup message;

An RRC connection reestablishment message;

an RRC connection configuration message;

RRC connection reconfiguration message.

These RRC messages may be messages that are interacted with in the process of establishing a connection between the terminal and the base station.

The switching time of the terminal to the target bandwidth part may be just between the listening moments of the two wake-up signals (Wake Up Signaling, WUS), or the connection establishment completion moment of the terminal to the base station, or just between the listening moments of the two WUS. The switching time and the monitoring time at this time are both within the effective range of WUS issued at the previous monitoring time, and WUS issued at the previous monitoring time at this time may be referred to as the current WUS. In this embodiment, the monitoring process of the PDCCH is performed according to the monitoring result of the wake-up signal indicated by the monitoring policy. The listening process here includes: monitoring or not monitoring the PDCCH.

If the BWP switching command and the RRC message are utilized to carry the monitoring policy, after the terminal is switched to the target bandwidth part or the RRC connection is established with the base station, the monitoring result of the previous wake-up signal at the current moment can be determined in time according to the monitoring policy, and PDCCH monitoring or non-monitoring in the wake-up moment mapped at the current moment can be performed according to the monitoring result.

The WUS is a low-power consumption detection signal, so that the terminal can consume very low power consumption to complete detection or monitoring of the WUS; and further determining whether the PDCCH is required to be monitored in the mapped wake-up period according to the monitoring result of the WUS monitoring. The terminal may skip the wake-up period when it does not monitor the WUS corresponding to the wake-up period, i.e. the sleep state is still maintained in the wake-up period, so that the PDCCH is not monitored, thereby further saving the power consumption of the terminal.

In some embodiments, the terminal may switch the traffic scenario, and the terminal may switch from the source bandwidth portion to the target bandwidth portion according to the configuration information of the bandwidth portion.

In other embodiments, there may be some terminals that are switched from the source bandwidth portion to the target bandwidth portion while bandwidth load balancing is performed.

But the terminal may just miss the listening time for the wake-up signal on the target bandwidth portion after switching to the target bandwidth. At this time, the terminal does not know how to perform the monitoring of the PDCCH in the awake period.

Establishing an RRC connection with the base station over the target bandwidth portion during the handover of the bandwidth portion may be accompanied; or the terminal needs to reestablish RRC connection with the base station in the process of switching from the non-connection state to the connection state; alternatively, a reconfiguration of the traffic needs to be performed for the terminal, for example, a DRX parameter or WUS configuration is configured for the terminal using an RRC connection reconfiguration message. The RRC connection reestablishment message may also be utilized to configure the DRX parameters or WUS configuration for the UE when reestablishment occurs.

The DRX parameters include, but are not limited to: the length of the DRX cycle.

The WUS configuration includes, but is not limited to: patterns of WUS signals, etc.

In summary, in the process of using the mobile service, the terminal has a requirement of switching the bandwidth part and a requirement of RRC connection establishment or reconfiguration or reconnection.

In view of this, in this embodiment, the terminal may monitor the PDCCH according to the monitoring result that the wake-up signal is currently monitored according to the monitoring policy, or may not monitor the PDCCH according to the monitoring result that the wake-up signal is not currently monitored; thus, the phenomenon of monitoring confusion of the terminal caused by the fact that the terminal does not know how to process the information is reduced.

In this embodiment, the PDCCH is monitored to monitor whether there is signal transmission on the PDCCH. The PDCCH may be used to transmit PDCCH signaling, etc. The PDCCH corresponds to a specific time-frequency resource, and when the terminal monitors the PDCCH in the wake-up period, the terminal can detect signals on the time-frequency resource mapped by the PDCCH, so that the PDCCH is monitored.

The listening results that WUS is listening to include, but are not limited to: monitoring that the signal strength of WUS on the corresponding bandwidth reaches an intensity threshold value and the like; if WUS is not monitored or the intensity of WUS monitored does not reach the intensity threshold, WUS may be considered not to be monitored.

In some embodiments, as shown in fig. 4A, the step S120 may include:

step S121: and switching from a source bandwidth part to a target bandwidth part according to a bandwidth part switching command or when an RRC message is received, if the monitoring time of a wake-up signal corresponding to the current time is missed, monitoring the PDCCH according to the monitored monitoring result of the wake-up signal according to the monitoring strategy.

As shown in fig. 4B, the step S120 may include:

step S122: and if the monitoring time of the wake-up signal corresponding to the current time is missed from the source bandwidth part to the target bandwidth part according to the bandwidth part switching command or when the RRC message is received, not monitoring the PDCCH according to the monitoring result that the wake-up signal is not monitored according to the monitoring strategy.

In some embodiments, the monitoring of the PDCCH according to the monitored result of the wake-up signal according to the monitoring policy includes:

and according to the monitored result of the wake-up signal according to the monitoring strategy, monitoring the PDCCH in a wake-up period within the effective range of the wake-up signal.

One WUS corresponds to a listening range of a specific PDCCH, which may be the aforementioned effective range.

For example, WUS has two mappings with wake-up periods, one is 1:1, i.e. one WUS may correspond to one awake period in a DRX cycle; the other is: 1: n and a WUS signal correspond to a plurality of wake-up periods, which are the effective ranges of the WUS map. N is a positive integer equal to or greater than 2.

Fig. 5 is a schematic diagram showing a mapping relationship between WUS and wake-up periods of 1:1, so that wake-up period 1, wake-up period 2 and wake-up period 3 correspond to WUS respectively, and WUS1, WUS2 and WUS3 respectively.

Fig. 6 shows that the mapping relationship between WUS and wake-up period is 1: schematic of N. If the terminal monitors 1 WUS, the terminal needs to monitor the PDCCH in all N wake-up periods mapped by the WUS. In fig. 6, one WUS corresponds to 3 wake periods, which are a wake period a, a wake period a+1, and a wake period a+2, respectively.

The range of effectiveness of the missed wake-up signal in this embodiment may include one or more wake-up periods.

In this embodiment, if the monitoring time of the current wake-up signal is missed, and the wake-up signal is regarded as the monitored result according to the monitoring policy, the PDCCH is monitored within the effective range of the wake-up signal, so as to reduce unnecessary power consumption of the terminal caused by monitoring outside the effective range.

In some embodiments, the monitoring of the PDCCH is performed during a wake-up period within an effective range of a wake-up signal, including:

and when the mapping relation between the wake-up signals and the wake-up periods is 1:1, and one wake-up period mapped by the wake-up signals is started, monitoring the PDCCH in the remaining time of the wake-up period mapped by the wake-up signals, which is started currently.

The current here may include: the moment the terminal switches to on the target bandwidth portion.

For example, if the mapping relationship between WUS and the wake-up period is 1:1, the effective range of WUS is a wake-up period, and the PDCCH is monitored in the wake-up period.

If the terminal not only misses the monitoring time of the current wake-up signal but also the wake-up period mapped by the wake-up signal is started when the terminal is switched from the source bandwidth part to the target bandwidth part or receives the RRC message, the PDCCH is monitored in the rest time of the wake-up period which is started from the beginning of the current time, so that the missing of important content issued by the PDCCH is reduced.

Referring to fig. 7, the mapping relationship between WUS and wake-up period is 1:1. Fig. 7 shows two cases:

case 1: after the wake-up period 1 of the target bandwidth part has started, the terminal switches to the target bandwidth part, and at this time, the terminal performs monitoring of the PDCCH from the current time to the end time of the wake-up period 1 according to the monitoring result regarded as monitoring the wake-up signal. Referring to fig. 2, the terminal switches to the target bandwidth portion at time T2, and the switching time T2 is located in the wake-up period n, and at this time, the terminal misses the listening time of the wake-up signal (the time indicated by the solid arrow in fig. 7), and listens for the PDCCH for the remaining time of the wake-up period n.

and when the mapping relation between the wake-up signal and the wake-up period is 1:1 and one wake-up period mapped by the wake-up signal is not started, monitoring the PDCCH in one wake-up period mapped by the wake-up signal.

When the mapping relation between the wake-up signal and the wake-up period is 1:1, and the wake-up period mapped by the wake-up signal is not started yet, that is, when the terminal is switched to the switching time on the target bandwidth part or receives the RRC message, the terminal monitors the PDCCH in the whole wake-up period mapped by the current wake-up time between the monitoring time of the current wake-up signal and the starting time of the wake-up period mapped by the wake-up signal.

Referring to case 2 shown in fig. 7:

the terminal switches to the target bandwidth part between the monitoring time of the current wake-up signal and the starting time of the wake-up period or receives the RRC message, and at this time, the terminal monitors the PDCCH mapped by the wake-up signal in the whole wake-up period.

Referring to fig. 7, when the terminal switches to the target bandwidth portion at the time T2 or completes and receives the RRC message, the time T2 is between the listening time of the current wake-up signal and the starting time of the wake-up period n mapped by the wake-up signal, so that the terminal may perform the listening of the PDCCH in the entire wake-up period n.

and when one wake-up signal corresponds to N wake-up periods, and the N wake-up periods mapped by the wake-up signal are started, monitoring PDCCH in the remaining time of the current wake-up period mapped by the wake-up signal and M wake-up periods after the remaining current wake-up period, wherein N is a positive integer not less than 2, and M is a positive integer less than N.

For example, n=4, m can be any whole integer less than 4, e.g., 3, 2, 1, or the like.

In this embodiment, the monitoring of the current wake-up signal is missed, and N wake-up periods mapped by the wake-up signal have already been started, and the monitoring of the PDCCH is performed in the remaining time of the current wake-up period that has already been started and in the remaining wake-up period. For example, when the terminal switches to the target bandwidth part or completes RRC connection establishment with the base station in the 1 st wake-up period, the terminal monitors PDCCH in the remaining time of the 1 st wake-up period and in the 2 nd to 4 th wake-up periods when the 1 st wake-up period is not completed.

And when one wake-up signal corresponds to N wake-up periods and the N wake-up periods mapped by the wake-up signal are started, monitoring PDCCH in M wake-up periods after the current wake-up period mapped by the wake-up signal is started, wherein N is a positive integer not less than 2, and M is a positive integer less than N.

In this embodiment, if the switching time of the terminal to the target bandwidth portion or the receiving time of the RRC message falls exactly in the current wake-up period, the terminal monitors only the PDCCH in M wake-up periods after the current wake-up period, and does not monitor the current wake-up period any more.

For example, n=3, m=2; if the terminal switches to the target bandwidth part or receives the RRC message in the time mapped by the 1 st awake period, in this embodiment, the terminal does not continue to monitor the PDCCH for the remaining time of the 1 st awake period that has already started but has not yet ended, but directly starts the PDCCH from the 2 nd awake period, and monitors the PDCCH in the 2 nd awake period and the 3 rd awake period.

And when one wake-up signal corresponds to N wake-up periods and M wake-up periods of the wake-up signal are not started, monitoring PDCCH in M wake-up periods mapped by the wake-up signal, wherein M is an integer smaller than or equal to N.

In some embodiments, if the terminal switches to the target bandwidth portion or completes RRC connection establishment with the base station in the case that the 1 st awake period of the N awake periods has not yet started, the terminal may monitor the PDCCH of the N awake periods mapped by the current awake signal.

In other embodiments, the terminal switches to the target bandwidth during the sleep period between two adjacent wake periods of the N wake periods or completes RRC connection establishment with the base station, the terminal will only monitor the PDCCH during the remaining M wake periods that have not yet started. For example, n=4, if the terminal switches to the target bandwidth after the end of the 2 nd wakeup period before the start of the 3 rd wakeup period or completes RRC connection establishment with the base station, the terminal only continues to monitor PDCCHs in the remaining 3 rd wakeup period and 4 th wakeup period.

As shown in fig. 8, one wake-up signal (indicated by a solid arrow indicated upward in fig. 8) corresponds to 3 wake-up periods, which are a wake-up period n, a wake-up period n+1, and a wake-up period n+2, respectively.

If the switching time of the terminal to the target bandwidth portion or the finishing time of finishing the RRC connection establishment with the base station is t1, the terminal misses the monitoring time of the wake-up signal, and is before the starting time of the 1 st wake-up period in the 3 wake-up periods mapped by the wake-up signal, at this time, the terminal monitors the PDCCH in the wake-up period n, the wake-up period n+1 and the wake-up period n+2 in sequence.

If the switching time of the terminal to the target bandwidth portion or the finishing time of finishing the RRC connection establishment with the base station is t2, the terminal misses the monitoring time of the wake-up signal, and after the 1 st wake-up period starts in the 3 wake-up periods mapped by the wake-up signal, the terminal may monitor the PDCCH in the remaining time of the wake-up period n, the wake-up period n+1 and the wake-up period n+2 in sequence.

If the switching time of the terminal to the target bandwidth portion or the finishing time of finishing the RRC connection establishment with the base station is t2, the terminal misses the monitoring time of the wake-up signal, and after the 1 st wake-up period starts in the 3 wake-up periods mapped by the wake-up signal, at this time, the terminal may monitor the PDCCH in the wake-up period n+1 and the wake-up period n+2 in sequence.

If the switching time of the terminal to the target bandwidth portion or the finishing time of finishing RRC connection establishment with the base station is t3, the terminal misses the monitoring time of the wake-up signal, and after the 1 st wake-up period ends and before the wake-up period n+1 starts in the 3 wake-up periods mapped by the wake-up signal, at this time, the terminal may monitor the PDCCH in the wake-up period n+1 and the wake-up period n+2 in sequence.

In some embodiments, the monitoring of the PDCCH is not performed according to the monitoring result that the wake-up signal is not monitored, including:

and according to the monitoring result that the wake-up signal is not monitored according to the monitoring strategy, the PDCCH is not monitored in the wake-up period in the effective range of the wake-up signal.

In some embodiments, according to the monitoring policy, the monitoring result of the current wake-up signal that misses the monitoring time is that WUS is not monitored, and if WUS is not monitored, the terminal can keep in the sleep state in the wake-up period, so that the power consumption of the terminal is further reduced.

In some embodiments, the monitoring of the PDCCH is not performed during the wake-up period within the effective range of the wake-up signal, including:

when the mapping relation between the wake-up signals and the wake-up periods is 1:1, and one wake-up period mapped by the wake-up signals is started, monitoring of the PDCCH is not carried out in the remaining time of the one wake-up period mapped by the wake-up signals which is started currently.

Here, a wake-up signal corresponds to a wake-up period, which means that the effective range of the wake-up signal includes a wake-up period.

At this time, a wake-up period corresponds to one wake-up signal, and since the wake-up signal which misses the listening time is determined not to be listened to according to the listening policy, the PDCCH is not listened to in the wake-up period mapped by the wake-up signal.

Such non-PDCCH monitoring includes: and not monitoring the PDCCH in the remaining time of the current wake-up period.

In another embodiment, the monitoring of the PDCCH is not performed during the wake-up period within the effective range of the wake-up signal, including:

when the mapping relation between the wake-up signal and the wake-up period is 1:1, and one wake-up period mapped by the wake-up signal is not started, the PDCCH is not monitored in one wake-up period mapped by the wake-up signal.

If the wake-up period mapped by the wake-up signal is not started, after the terminal is switched to the target bandwidth part, the terminal keeps the sleep state in the wake-up period mapped by the wake-up signal which is not started, so that the PDCCH is not monitored.

In some embodiments, the method further comprises:

if the monitoring time of the wake-up signal corresponding to the current time is missed, the mapping relation between the wake-up signal and the wake-up period is 1:1, and when one wake-up period mapped by the wake-up signal is started, the monitoring of the PDCCH is continued in the residual time in the started wake-up period.

At this time, the mapping relationship is 1:1, and even if the monitoring result indicated by the monitoring policy is not monitored, since the mapping relationship is 1:1 and the corresponding wake-up period has already been started, the monitoring of the PDCCH is continued in the remaining period of the wake-up signal that has already been started.

In other embodiments, the monitoring of the PDCCH is not performed during the wake-up period within the effective range of the wake-up signal, including:

when one wake-up signal corresponds to N wake-up periods and the N wake-up periods mapped by the wake-up signal are started, monitoring of the PDCCH is not carried out in the remaining time of the current wake-up period which is started by the wake-up signal and M wake-up periods after the remaining current wake-up period, wherein N is a positive integer not less than 2, and M is a positive integer less than N.

I.e. the terminal switches to the target bandwidth part in the time of the N wake-up periods mapped by the wake-up signal, at this time, the terminal directly does not monitor the PDCCH from the remaining time of the current wake-up period that has already been started and the remaining M wake-up periods.

The current wake-up period is a wake-up period including a current time.

When one wake-up signal corresponds to N wake-up periods and the N wake-up periods of the wake-up signal map have been started, continuing to monitor the PDCCH in the remaining time of the current wake-up period of the wake-up signal map that has been started, and not monitoring the PDCCH in M wake-up periods after the remaining current wake-up period, where N is a positive integer not less than 2 and M is a positive integer less than N.

and when the M wake-up periods of the wake-up signal are not started, monitoring of the PDCCH is not carried out in the M wake-up periods mapped by the wake-up signal, wherein M is an integer smaller than or equal to N.

Here, one wake-up signal corresponds to N wake-up periods, and it is explained that the effective range of one wake-up signal includes N wake-up periods.

For example, the terminal may switch to the target bandwidth portion before the 1 st wake-up period has not yet started, and then does not monitor the PDCCH for N wake-up periods mapped by the wake-up signal.

For another example, the terminal may switch to the target bandwidth portion at the sleep time between two adjacent wakeup periods of the N wakeup periods, and at this time, the terminal does not monitor the PDCCH in M wakeup periods after the current time.

In some embodiments, the bandwidth part handover command or RRC message may indicate the listening policy through one or more indication bits. In this embodiment, the indication bit may be 1 bit.

Specifically, when the bandwidth part switching command or the indication bit included in the RRC message is a first value, it is determined that the missed wake-up signal has the monitored monitoring result;

and when the bandwidth part switching command or the indication bit contained in the RRC message is a second value, determining that the missed wake-up signal has the monitoring result which is not monitored.

Therefore, under the condition that only one indication bit is added, the missed indication of the monitoring result of the current WUS is completed, and the method has the characteristics of simplicity and convenience in indication and strong compatibility with the prior art.

As shown in fig. 9, this embodiment provides a policy issuing method, which includes:

step S200: and issuing a bandwidth part switching command or an RRC message containing a monitoring strategy, wherein the monitoring strategy is used for determining a monitoring result of a wake-up signal for monitoring the PDCCH.

The method provided by the embodiment can be applied to a base station. The base station can issue the monitoring strategy according to the service frequency of the current terminal and the current data transmission requirement. If the current business frequency is higher than the threshold value or the current data transmission requirement exists, a monitoring strategy indicating that the wake-up signal is monitored is issued, and if the current business frequency is lower than the threshold value or the current data transmission requirement does not exist, a monitoring strategy indicating that the wake-up signal is not monitored is issued.

In this embodiment, the RRC message may include one of the following indications:

an RRC connection setup message;

if the monitoring time of the wake-up signal is missed after the bandwidth part switching command or the RRC message is received for a preset time, the monitoring processing of the PDCCH is carried out according to the monitoring result of the wake-up signal indicated by the protocol information.

The listening times of the possibly corresponding wake-up signals after the predetermined time interval are different, e.g. the predetermined time may comprise a time difference between the listening times of at least two adjacent wake-up signals.

In this way, after the terminal switches to the target bandwidth portion or receives the RRC message for a period of time, the monitoring process of the PDCCH may be performed according to the monitoring result of the wake-up signal indicated by the protocol information in the communication protocol.

The RRC message includes one of:

an RRC connection setup message;

an RRC connection reestablishment message;

an RRC connection configuration message;

Several specific examples are provided below in connection with any of the embodiments described above:

example 1:

the base station carries the monitoring policy of WUS in the BWP switch command or in the RRC message (including RRC connection reconfiguration and RRC connection reestablishment, RRC connection establishment), so that the terminal can conveniently perform WUS monitoring processing according to the monitoring policy of WUS given by the base station after BWP switch or after RRC connection reconfiguration.

Example 2:

the monitoring policy of WUS sent by the base station indicates that after BWP handover or after receiving an RRC message (including RRC connection reconfiguration, RRC connection reestablishment, and RRC connection establishment), if the current monitoring moment of WUS is missed, the monitoring policy of WUS is adopted, that is, the processing is performed according to WUS monitoring or the processing is performed according to WUS not monitoring.

As an embodiment, it may be an explicit indication bit value of "1", which means that after BWP handover or after receiving RRC messages (including RRC connection reconfiguration and RRC connection reestablishment, RRC connection establishment), the terminal processes the current missed WUS listening time according to WUS listening by using the listening policy adopted when the WUS listening time is missed.

As an embodiment, it may be an explicit indication bit value of "0", which means that after the BWP handover or after receiving the RRC message (including RRC connection reconfiguration and RRC connection reestablishment, RRC connection establishment), the terminal misses the listening time of the current WUS, and the listening policy adopted is to process the current missed WUS listening time according to that the WUS is not listening.

For example, in a BWP handover command or after receiving an RRC message (but not limited to at least one of the following RRC connection reconfiguration message and RRC connection reestablishment message, RRC connection setup message), if the listening time of the current WUS is missed, the terminal adopts a listening policy that the current missed WUS listening time is processed according to WUS listening, i.e. listening to a wake-up period in the effective range of the subsequent WUS:

as an example, for 1:1, after BWP handover or after receiving an RRC message (including RRC connection reconfiguration and RRC connection reestablishment, RRC connection establishment), may have already started for the wake-up period corresponding to the current WUS, the terminal still listens to the current remaining wake-up period time.

As an example, for 1:1, after BWP handover or after receiving an RRC message (including but not limited to at least one of the following: RRC connection reconfiguration message and RRC connection reestablishment message, RRC connection setup message), it may be that the wake-up period corresponding to WUS has not yet started, the terminal listens to the instant of the wake-up period to be started.

As an example, for 1: the scenario of the N mapping relationship may be that after BWP handover or after receiving RRC messages (including RRC connection reconfiguration and RRC connection reestablishment, RRC connection establishment) a corresponding awake period has already been started for WUS, at which time the current remaining awake period time is monitored from the time of handover to the new BWP time; and continues to monitor the remaining M upcoming wakeup period times. And M is the number of wake-up periods missed by the terminal in N.

For example: assuming n=4 and the terminal switches to the target BWP at the second wake-up period, the terminal listens from the remaining time of the second wake-up period, which includes a partial wake-up period and the remaining 2 wake-up periods.

As an example, for 1: the scenario of the N mapping relation, after BWP handover or after receiving an RRC message (including RRC connection reconfiguration and RRC connection reestablishment, RRC connection establishment), may be that the wake-up period corresponding to the current WUS has already started, and the terminal will continue listening to the remaining M upcoming wake-up period moments from the moment of handover to the target BWP. And M is the number of wake-up periods missed by the terminal in N.

For example: assuming n=4 and the terminal switches to a new BWP at the second wake-up period, the terminal starts listening from the 3 rd wake-up period instant, i.e. continues listening from the remaining 2 wake-up periods.

As an example, for 1: the scenario of the N mapping relationship may not yet be started for the wake-up period corresponding to the current WUS after BWP handover or after receiving an RRC message (including RRC connection reconfiguration and RRC connection reestablishment, RRC connection establishment), and at this time, the remaining M upcoming wake-up period times continue to be monitored from the time of handover to the target BWP.

Example 2:

the terminal processes the missed WUS monitoring time according to the non-WUS monitoring, i.e. does not monitor the wake-up period in the effective range of the subsequent WUS, in the BWP switching command or after receiving the RRC message.

As an example, for 1:1, after BWP handover or after receiving an RRC message (including RRC connection reconfiguration and RRC connection reestablishment, RRC connection establishment), a wake-up period corresponding to WUS has already started, the terminal does not monitor for the current remaining wake-up period instant.

As an example, for 1:1, after BWP handover or after receiving RRC message, it may be that the wake-up period corresponding to WUS has not yet started, and the terminal does not monitor the instant of the wake-up period to be started.

As an example, for 1: the scenario of the N mapping relationship may be that the wake-up period corresponding to WUS has already started after BWP handover or after receiving RRC message, and the terminal will not monitor the wake-up period within the effective range of the current WUS.

As an example, for 1: the scenario of the N mapping relationship may be that after the BWP handover or after receiving the RRC message, the wake-up period corresponding to WUS has already started, and at this time, the terminal will continue to maintain the original wake-up period timer, i.e. continue to monitor the wake-up period that is currently in effect, but not monitor the complete wake-up period after the WUS is in the effective range.

As an example, for 1: in the scenario of the N mapping relationship, after BWP handover or after receiving an RRC message (including RRC connection reconfiguration and RRC connection reestablishment, RRC connection establishment), a wake-up period corresponding to WUS may not yet be started, and at this time, the terminal will not monitor for a wake-up period within the effective range of the current WUS.

Example 3:

whether the terminal listens to WUS after BWP handover or after receiving RRC message can also be based on protocol specification:

as an embodiment, the protocol specifies that after a BWP handover or after receiving an RRC message, the terminal adopts a listening policy that the current missed WUS listening time is handled as WUS listening after the missed WUS listening time.
