As shown in FIG. 3, this embodiment provides a method for monitoring the physical downlink control channel PDCCH, which includes:

Step S110: Receive the bandwidth part switching command or the monitoring strategy included in the radio resource control RRC message;

Step S120: Perform PDCCH monitoring processing according to the monitoring result of the wake-up signal indicated by the monitoring strategy.

The bandwidth part (Band Width Part, BWP) switching command is used to trigger the terminal to switch from the source bandwidth part to the target bandwidth part.

The switching from the source bandwidth part to the target bandwidth part here includes:

The terminal establishes a connection with the base station through the source bandwidth part, changed to: the terminal establishes a connection with the base station through the target bandwidth part;

and / or,

The terminal uses the source bandwidth part to interact with the base station, which is changed to: the terminal interacts with the base station through the target bandwidth part. The content of interaction here includes: data, signal, and/or signaling.

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

RRC connection establishment message;

RRC connection re-establishment message;

RRC connection configuration message;

RRC connection reconfiguration message.

These RRC messages can all be messages exchanged during the process of establishing a connection between the terminal and the base station.

The handover time for the terminal to switch to the target bandwidth portion may be exactly between the listening moments of two wake-up signals (Wake Up Signaling, WUS), or the time when the connection between the terminal and the base station is established, or it may be exactly between two Between the monitoring moments of WUS. The switching time and the monitoring time at this time are both within the effective range of the WUS issued at the previous monitoring time, and the WUS issued at the previous monitoring time of the current time can be called the current WUS. In this embodiment, the PDCCH monitoring process is performed according to the monitoring result of the wake-up signal indicated by the monitoring strategy. The monitoring processing here includes: monitoring the PDCCH or not monitoring the PDCCH.

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

WUS is a low-power detection signal. In this way, the terminal can complete WUS detection or monitoring with very low power consumption; further based on the monitoring results of WUS monitoring, determine whether it is necessary to perform PDCCH during the mapped wake-up period. monitor. If the terminal does not monitor the WUS corresponding to the wake-up period, the wake-up period can be skipped, that is, the sleep state is still maintained during the wake-up period, so that the PDCCH is not monitored, so as to further save the power consumption of the terminal.

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

In other embodiments, during bandwidth load balancing, some terminals may be switched from the source bandwidth part to the target bandwidth part.

However, after the terminal switches to the target bandwidth, it may just miss the listening moment of the wake-up signal on the target bandwidth part. At this time, the terminal does not know how to monitor the PDCCH during the wake-up period.

The handover process of the bandwidth part may be accompanied by the establishment of an RRC connection with the base station on the target bandwidth part; or the terminal needs to re-establish the RRC connection with the base station during the process of switching from the non-connected state to the connected state; or, the terminal needs to perform services Reconfiguration, for example, using an RRC connection reconfiguration message to configure DRX parameters or WUS configuration for the terminal. When re-establishment occurs, the RRC connection re-establishment message can also be used to configure DRX parameters or WUS configuration for the UE.

The DRX parameter includes but is not limited to: the length of the DRX cycle.

The WUS configuration includes, but is not limited to: WUS signal patterns and the like.

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

In view of this, in this embodiment, the terminal will monitor the PDCCH channel according to the monitoring result of the currently monitored wake-up signal according to the monitoring strategy, or not perform the monitoring of the PDCCH channel according to the monitoring result of the currently not monitored wake-up signal; In this way, it reduces the monitoring confusion of the terminal that the terminal does not know how to handle.

In this embodiment, the monitoring of the PDCCH is to monitor whether there is signal transmission on the PDCCH. PDCCH can be used to transmit PDCCH signaling and so on. The PDCCH corresponds to a specific time-frequency resource. When the terminal monitors the PDCCH during the wake-up period, it can perform signal detection on the time-frequency resource mapped by the PDCCH, so as to realize the monitoring of the PDCCH.

The monitoring results monitored by WUS include but are not limited to: monitoring the signal strength of WUS on the corresponding bandwidth reaches the strength threshold, etc.; if WUS is not monitored or the strength of the monitored WUS does not reach the strength threshold, it can be considered that WUS is not Overheard.

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

Step S121: Switch from the source bandwidth part to the target bandwidth part according to the bandwidth part switching command or when the RRC message is received, if the listening moment of the wake-up signal corresponding to the current moment is missed, according to the listening strategy according to the wake-up The monitoring result of the signal being monitored is monitored for the PDCCH.

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

Step S122: Switch from the source bandwidth part to the target bandwidth part according to the bandwidth part switching command or when the RRC message is received, if the listening moment of the wake-up signal corresponding to the current moment is missed, according to the listening strategy according to the wake-up If the signal is not monitored, the PDCCH monitoring is not performed.

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

According to the monitoring result that the wake-up signal is monitored according to the monitoring strategy, the PDCCH is monitored during the wake-up period within the effective range of the wake-up signal.

One WUS corresponds to a specific PDCCH monitoring range, and the monitoring range may be the aforementioned effective range.

For example, WUS and wake-up period have two mapping relationships, one is 1:1, that is, one WUS can correspond to one wake-up period in the DRX cycle; the other is: 1:N, and one WUS signal corresponds to multiple Wake-up periods, these wake-up periods are the effective range of the WUS mapping. N is a positive integer equal to or greater than 2.

Figure 5 shows a schematic diagram of a 1:1 mapping relationship between WUS and wake-up period. In this way, wake-up period 1, wake-up period 2 and wake-up period 3 respectively correspond to their respective WUSs, and are WUS1, WUS2, and WUS3 respectively.

Fig. 6 shows a schematic diagram of the mapping relationship between WUS and wake-up period of 1:N. In this way, if the terminal detects 1 WUS, it needs to monitor the PDCCH during the N wake-up periods mapped by the WUS. In Figure 6, one WUS corresponds to three wake-up periods, namely, wake-up period a, wake-up period a+1, and wake-up period a+2.

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

In this embodiment, if the current monitoring moment of the wake-up signal is missed, according to the monitoring strategy, when the wake-up signal is considered to be monitored as the monitoring result, the PDCCH monitoring will be performed within the effective range of the wake-up signal to reduce the out-of-effective range Unnecessary power consumption of the terminal caused by the monitoring.

In some embodiments, monitoring the PDCCH during the wake-up period within the effective range of the wake-up signal includes:

When the mapping relationship between the wake-up signal and the wake-up period is 1:1, and a wake-up period mapped by the wake-up signal has started, PDCCH monitoring is performed within the remaining time of a currently started wake-up period mapped by the wake-up signal.

The current here may include: the time when the terminal switches to the target bandwidth part.

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

If the terminal switches from the source bandwidth part to the target bandwidth part or receives an RRC message, it not only misses the listening moment of the current wake-up signal, but also the wake-up period mapped by the wake-up signal has begun. The remaining time of the initial wake-up period monitors the PDCCH, thus reducing the missed important content delivered by the PDCCH.

Referring to Figure 7, the mapping relationship between WUS and wake-up period is 1:1. Figure 7 shows that there are two situations:

Case 1: After the wake-up period 1 of the target bandwidth part has started, the terminal switches to the target bandwidth part. At this time, the terminal performs the wake-up period 1 from the current time to the end time according to the monitoring policy execution as the monitoring result of the wake-up signal. PDCCH monitoring between. Referring to Figure 2, the terminal switches to the target bandwidth part at time T2, and the switching time T2 is in the wake-up period n. At this time, the terminal missed the listening time of the wake-up signal (the time indicated by the upward solid arrow in Figure 7), PDCCH monitoring is performed in the remaining time of the wake-up period n.

In some embodiments, monitoring the PDCCH during the wake-up period within the effective range of the wake-up signal includes:

When the mapping relationship between the wake-up signal and the wake-up period is 1:1, and a wake-up period mapped by the wake-up signal has not yet started, PDCCH monitoring is performed in a wake-up period mapped by the wake-up signal.

When the mapping relationship between the wake-up signal and the wake-up period is 1:1, and the wake-up period of the wake-up signal mapping has not yet started, it means that the terminal switches to the switching time on the target bandwidth part or when the RRC message is received. Between the monitoring moment of the current wake-up signal and the start time of the wake-up period mapped by the wake-up signal, the terminal will monitor the PDCCH during the entire wake-up period mapped by the current wake-up time.

Refer to Case 2 shown in Figure 7:

When the terminal switches to the target bandwidth part or receives an RRC message between the monitoring moment of the current wake-up signal and the start moment of the wake-up period, the terminal will monitor the PDCCH in the entire wake-up period mapped by the wake-up signal.

As shown in FIG. 7, when the terminal switches to the target bandwidth portion at time T2 or completes and receives the RRC message, time T2 is between the listening time of the current wake-up signal and the start time of the wake-up period n mapped by the wake-up signal In this way, the terminal will monitor the PDCCH during the entire wake-up period n.

In some embodiments, monitoring the PDCCH during the wake-up period within the effective range of the wake-up signal includes:

When one wake-up signal corresponds to N wake-up periods, and the N wake-up periods mapped by the wake-up signal have started, within the remaining time of the current wake-up period mapped by the wake-up signal and M wake-ups after the remaining current wake-up period During the time period, PDCCH monitoring is performed, where 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 integer less than 4, for example, 3, 2, or 1.

In this embodiment, the monitoring of the current wake-up signal is missed, and the N wake-up periods mapped by the wake-up signal have started, and the PDCCH monitoring is performed within the remaining time of the current wake-up period that has started and the remaining wake-up period . For example, if the terminal switches to the target bandwidth part or completes the establishment of the RRC connection with the base station during the first wake-up period, the terminal will remain in the first wake-up period before the end of the first wake-up period. PDCCH monitoring is performed during the time and the second to fourth wake-up periods.

In some embodiments, monitoring the PDCCH during the wake-up period within the effective range of the wake-up signal includes:

When one wake-up signal corresponds to N wake-up periods, and the N wake-up periods mapped by the wake-up signal have begun, PDCCH monitoring is performed within M wake-up periods after the current wake-up period mapped by the wake-up signal has started, where, N is a positive integer not less than 2, and M is a positive integer less than N.

In this embodiment, if the terminal switches to the switching time on the target bandwidth portion or the receiving time of the RRC message, which falls within the current wake-up period, it will only perform PDCCH for M wake-up periods after the current wake-up period. , Instead of monitoring the current wake-up period.

For example, N=3, M=2; if the terminal switches to the target bandwidth part or receives an RRC message within the time mapped by the first wake-up period, in this embodiment, the terminal will not be PDCCH monitoring will continue for the remaining time of the first wake-up period, but PDCCH monitoring will start directly from the second wake-up period, and PDCCH monitoring will be performed in the second and third wake-up periods.

In some embodiments, monitoring the PDCCH during the wake-up period within the effective range of the wake-up signal includes:

When one wake-up signal corresponds to N wake-up periods, and the M wake-up periods of the wake-up signal have not yet started, PDCCH monitoring is performed within the M wake-up periods mapped by the wake-up signal, and M is an integer less than or equal to N.

In some embodiments, when the terminal switches to the target bandwidth part or completes the RRC connection establishment with the base station when the first wake-up period of the N wake-up periods has not yet started, the terminal will perform the current wake-up signal mapping N PDCCH monitoring during a wake-up period.

In other embodiments, the terminal switches to the target bandwidth or completes the establishment of the RRC connection with the base station during the sleep period between two adjacent wake-up periods among the N wake-up periods, the terminal will only monitor the unstarted PDCCH in the remaining M wake-up periods. For example, N=4, if the terminal switches to the target bandwidth or completes the RRC connection establishment with the base station after the second wake-up period ends and before the third wake-up period starts, the terminal will only continue to monitor the remaining third PDCCH in the wake-up period and the fourth wake-up period.

As shown in FIG. 8, one wake-up signal (represented by a solid arrow pointing upward in FIG. 8) corresponds to three wake-up periods, namely, wake-up period n, wake-up period n+1, and wake-up period n+2.

If the terminal switches to the target bandwidth part of the handover time or the completion time of completing the RRC connection establishment with the base station is t1, the terminal will miss the listening moment of the wake-up signal, and it is the first of the 3 wake-up periods mapped by the wake-up signal Before the start time of the wake-up period, at this time, the terminal will monitor 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 terminal switches to the switching time on the target bandwidth part or the completion time of completing the RRC connection establishment with the base station is t2, the terminal will miss the listening moment of the wake-up signal, and it is the first of the three wake-up periods mapped by the wake-up signal After the wake-up period starts, at this time, the terminal may sequentially monitor the PDCCH during the remaining time of the wake-up period n, the wake-up period n+1, and the wake-up period n+2.

If the terminal switches to the switching time on the target bandwidth part or the completion time of completing the RRC connection establishment with the base station is t2, the terminal will miss the listening moment of the wake-up signal, and it is the first of the three wake-up periods mapped by the wake-up signal After the wake-up period starts, at this time, the terminal can monitor the PDCCH in the wake-up period n+1 and the wake-up period n+2 in sequence.

If the terminal switches to the target bandwidth part of the handover time or the completion time of the completion of the RRC connection establishment with the base station is t3, the terminal will miss the listening moment of the wake-up signal, and it is the first of the three wake-up periods mapped by the wake-up signal After the wake-up period ends and before the wake-up period n+1 starts, at this time, the terminal may monitor the PDCCH during the wake-up period n+1 and the wake-up period n+2 in sequence.

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

According to the monitoring result that the wake-up signal is not monitored according to the monitoring strategy, no PDCCH monitoring is performed during the wake-up period within the effective range of the wake-up signal.

In some embodiments, according to the monitoring strategy, the monitoring result of the current wake-up signal that missed the monitoring moment is that WUS is not monitored. If WUS is not monitored, the terminal can continue to stay dormant during the wake-up period, thus further reducing the terminal Power consumption.

In some embodiments, not performing PDCCH monitoring during the wake-up period within the effective range of the wake-up signal includes:

When the mapping relationship between the wake-up signal and the wake-up period is 1:1, and a wake-up period mapped by the wake-up signal has started, the PDCCH is not performed within the remaining time of a wake-up period mapped by the currently started wake-up signal monitor.

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

At this time, a wake-up signal corresponds to a wake-up period. Since it is determined that the wake-up signal that missed the monitoring moment is not monitored according to the monitoring strategy, the PDCCH monitoring is no longer performed during the wake-up period mapped by the wake-up signal.

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

In another embodiment, during the wake-up period within the effective range of the wake-up signal, no PDCCH monitoring is performed, including:

When the mapping relationship between the wake-up signal and the wake-up period is 1:1, and a wake-up period mapped by the wake-up signal has not yet started, in a wake-up period mapped by the wake-up signal, PDCCH monitoring is not performed.

If the wake-up period mapped by the wake-up signal has not yet started, after the terminal switches to the target bandwidth part, it will remain in the dormant state during the wake-up period mapped by the wake-up signal that has not yet started, so as not to monitor the PDCCH.

In some embodiments, the method further includes:

If the monitoring moment of the wake-up signal corresponding to the current moment is missed, the mapping relationship between the wake-up signal and the wake-up period is 1:1, and when one of the wake-up periods mapped by the wake-up signal has already started, PDCCH monitoring continues for the remaining time in the initial wake-up period.

At this time, the mapping relationship is 1:1. Even if the monitoring result indicated by the monitoring strategy is not monitored, because the mapping relationship is 1:1 and the corresponding wake-up period has started, then the wake-up signal that has started Continue to monitor the PDCCH in the remaining time period.

In other embodiments, not performing PDCCH monitoring during the wake-up period within the effective range of the wake-up signal includes:

When one wake-up signal corresponds to N wake-up periods, and the N wake-up periods mapped by the wake-up signal have started, within the remaining time of the current wake-up period mapped by the wake-up signal and M wake-ups after the remaining current wake-up period During the time period, PDCCH monitoring is not performed, where N is a positive integer not less than 2, and M is a positive integer less than N.

That is, the terminal switches to the target bandwidth part within the time of N wake-up periods mapped by the wake-up signal. At this time, the terminal directly does not perform PDCCH from the remaining time of the current wake-up period that has started and the remaining M wake-up periods Monitoring.

The current wake-up period is a wake-up period including the current moment.

In other embodiments, not performing PDCCH monitoring during the wake-up period within the effective range of the wake-up signal includes:

When one wake-up signal corresponds to N wake-up periods, and the N wake-up periods mapped by the wake-up signal have started, in the case of continuing to monitor the PDCCH for the remaining time of the current wake-up period mapped by the wake-up signal, the remaining current During the M wake-up periods after the wake-up period, PDCCH monitoring is not performed, where N is a positive integer not less than 2 and M is a positive integer less than N.

In some embodiments, not performing PDCCH monitoring during the wake-up period within the effective range of the wake-up signal includes:

One wake-up signal corresponds to N wake-up periods, and when the M wake-up periods of the wake-up signal have not yet started, PDCCH monitoring is not performed within the M wake-up periods mapped by the wake-up signal, and M is an integer less than or equal to N.

Here, one wake-up signal corresponds to N wake-up periods, which means that the effective range of one wake-up signal includes N wake-up periods.

For example, the terminal may switch to the target bandwidth part before the first wake-up period starts, and at this time, it does not perform PDCCH monitoring during the N wake-up periods mapped by the wake-up signal.
