It should be understood that the terms "system" and "network" are often used interchangeably herein.

In a Long Term Evolution (LTE) system, a concept of Discontinuous Reception (DRX) is proposed. Specifically, the main idea of DRX is: the network can configure the terminal to wake up (DRX ON) at a time predicted by the network, and the terminal monitors a downlink control channel; meanwhile, the network can also configure the terminal to sleep (DRX OFF) at a time predicted by the network, that is, the terminal device does not need to monitor the downlink control channel. Thus, if network device 120 has data to transmit to terminal device 110, network device 120 may schedule terminal device 110 during the time that terminal device 110 is in DRX ON, and during DRC OFF, terminal power consumption may be reduced due to radio OFF.

For example, as shown in fig. 2, a DRX cycle (cycle) configured by the network device for the terminal device is composed of an active period (On Duration) and a dormant period (Opportunity for DRX). For the RRC connected mode (RRC connected), if the terminal device configures the DRX function, the terminal device may monitor and receive the PDCCH during an Active Time (Active Time); and does not receive a PDCCH within a Non Active Time (Non Active Time) to reduce power consumption.

If the terminal configures DRX, the terminal needs to monitor the PDCCH at a DRX Active Time (DRX Active Time), where the DRX Active Time includes the following situations:

1. a DRX continuous timer (DRX-onDurationTimer), a DRX inactivity timer (DRX-inactivity timer), a DRX downlink retransmission timer (DRX-retransmission timer dl), a DRX uplink retransmission timer (DRX-retransmission timer ul), and any one of a random access contention resolution timer (ra-ContentionResolutionTimer) are running.

2. A Scheduling Request (SR) is transmitted on a Physical Uplink Control Channel (PUCCH) and is in a waiting (pending) state.

3. In the contention-based random access process, the terminal does not receive a primary initial transmission indicated by a Physical Downlink Control Channel (PDCCH) scrambled by a Cell Radio Network Temporary identifier (C-RNTI) after successfully receiving a random access response.

In order to provide a larger data transmission rate, the NR system supports Carrier Aggregation (CA) technology, and for a terminal device supporting the CA technology, the terminal device may be configured with one Primary Cell (PCell) and one or more Secondary cells (scells) for the terminal device, where the SCell may have both active and inactive states, and when the SCell is in the active state, the terminal device may perform data transceiving on the SCell.

The network device may Control the activation and deactivation state switching of the SCell by sending a Media Access Control Element (MAC CE), but based on the switching manner, there is often a large switching delay, so as to enable the terminal device to more quickly implement a behavior transition from not monitoring the PDCCH to monitoring the PDCCH or vice versa on the SCell, a sleep (dormant) behavior is introduced for the SCell, and the network device may instruct, through the PDCCH, to switch from the sleep (dormant) behavior to the non-dormant behavior (non-dormant) on a certain SCell, or from the non-dormant behavior to the dormant behavior.

Fig. 3 is a schematic flow chart of a method 200 for wireless communication according to an embodiment of the present disclosure. The method 200 may be performed by a terminal device in the communication system shown in fig. 1, and as shown in fig. 3, the method 200 may include at least part of the following:

s210, a terminal device obtains at least two wake-up signal WUS configurations, one WUS configuration of the at least two WUS configurations corresponds to one DRX group of at least two Discontinuous Reception (DRX) groups, and the WUS configuration is used for indicating monitoring occasions of the WUS of the corresponding DRX group, wherein the at least two DRX groups correspond to a Media Access Control (MAC) entity of the terminal device, and each DRX group is associated with at least one auxiliary cell;

s220, the terminal device monitors a first WUS corresponding to a first DRX group of the at least two DRX groups according to the monitoring opportunity of the first WUS, wherein the first WUS is used for indicating the target behavior of the terminal device on the activated auxiliary cell associated with the first DRX group, and the target behavior is dormant behavior;

s230, the terminal device switches the behavior of the terminal device in the activated secondary cell associated with the first DRX group according to the first WUS.

It should be understood that, in the embodiment of the present application, the sleep class behavior (sleep-related behavior) may include whether to sleep, that is, may include a dormancy behavior and a non-dormancy behavior, or may also include more sleep class behaviors, for example, the dormancy behavior, the non-dormancy behavior, a semi-sleep behavior, and the like, in some embodiments, the multiple sleep class behaviors may correspond to different sleep levels, each sleep level corresponds to different executable behaviors and/or non-executable behaviors, for example, the higher the sleep level is, the less the terminal performs the behaviors, for example, the dormancy behavior may be set to include that the terminal does not monitor PDCCH, and the non-dormancy behavior includes that the terminal monitors PDCCH, so that in different scenarios, the terminal may be controlled by the WUS to perform different sleep class behaviors on the secondary cell, which is beneficial for both power saving and normal data communication of the terminal, and the user experience is improved.

It should be noted that, in this embodiment of the present application, that the target behavior is a dormant class behavior may mean that the target behavior belongs to the dormant class behavior, or the target behavior includes one or more of the dormant class behaviors. Taking the example that the dormancy type behaviors include a dormancy behavior and a non-dormancy behavior, the target behavior can be the dormancy behavior or the non-dormancy behavior.

It should be understood that, in the embodiment of the present application, one Media Access Control (MAC) entity of the terminal device may configure at least two DRX groups (groups), each DRX group corresponds to one wake-up signal (WUS) configuration, and each WUS configuration may be used to indicate a monitoring occasion (monitoring occasion) of the WUS of the corresponding DRX group, so that the WUS configuration may also be referred to as a WUS monitoring occasion configuration.

In this embodiment, each DRX group may be associated with at least one secondary cell, and in some embodiments, the network device may send, to the terminal device, cell configuration information, where the cell configuration information may be used to indicate a target cell associated with each DRX group of the at least two DRX groups, and in some embodiments, the target cell may include only at least one secondary cell, or the target cell may also include a primary cell and at least one secondary cell.

In some embodiments, the network device may also configure the terminal device with DRX parameters for each of the at least two DRX groups, which may include, by way of example and not limitation, at least one of:

1. drx-onDurationTimer: duration of terminal device wake-up from one DRX cycle;

2. DRX slot offset (DRX-SlotOffset): the terminal equipment starts the time delay of the drx onDurationTimer;

3. drx-inactivytytimer: after receiving a PDCCH indicating uplink initial transmission or downlink initial transmission, the terminal equipment continues to monitor the duration of the PDCCH;

4. drx-retransmission timerdl: the terminal equipment monitors the longest duration of a PDCCH (physical downlink control channel) indicating downlink retransmission scheduling, wherein each downlink HARQ process except a broadcast Hybrid Automatic Repeat reQuest (HARQ) process corresponds to one drx-retransmission TimerDL;

5. drx-retransmission timerll: the terminal equipment monitors the longest duration of a PDCCH (physical downlink control channel) indicating uplink retransmission scheduling, wherein each uplink HARQ process corresponds to one drx-retransmission TimerUL;

6. DRX long cycle start offset (DRX-LongCycleStartOffset): configuring a long DRX cycle and a subframe offset at which the long DRX cycle and a short DRX cycle start;

7. DRX short cycle (DRX-short cycle): a short DRX cycle;

8. DRX short cycle timer (DRX-ShortCycleTimer): duration that the terminal device is in a short DRX cycle (and does not receive any PDCCH);

9. DRX HARQ round trip time downlink timer (round-trip time, RTT) -TimerDL): terminal equipment expects to receive the minimum waiting time required by the PDCCH indicating downlink scheduling, and each downlink HARQ process except the broadcast HARQ process corresponds to one drx-HARQ-RTT-TimerDL;

10. DRX HARQ round trip time uplink timer (DRX-HARQ-RTT-timerll): the UE expects to receive the minimum latency required by the PDCCH indicating uplink scheduling, one drx-HARQ-RTT-timerll for each uplink HARQ process.

It should be understood that, in this embodiment of the present application, a secondary cell associated with one DRX group may also be referred to as a secondary cell corresponding to one DRX group, or may also be referred to as a secondary cell included in one DRX group, and the like, and the secondary cell associated with one DRX group may use the same set of DRX parameter configuration.

In some embodiments, the monitoring occasion of the WUS corresponding to each DRX group may be a specific time before the start time of the DRX cycle, and the monitoring occasion of the WUS may be located on a PCell or an SCell associated with the DRX group. Thus, the indication of a WUS is valid for that DRX cycle, and if the terminal device receives another WUS before the next DRX cycle, the behavior on the SCell in the next DRX cycle is determined according to the indication of the other WUS.

Further, the terminal device may determine whether to monitor the WUS at the WUS monitoring occasion corresponding to each DRX group based on the WUS configuration of the DRX group. The monitoring of the first WUS corresponding to the first DRXgroup is taken as an example.

As an example, if the WUS monitoring occasion corresponding to the first DRX group is in the DRX Active Time period of the first DRX group, the terminal device does not monitor the first WUS at the WUS monitoring occasion corresponding to the first DRX group.

As another example, if the WUS monitoring occasion corresponding to the first DRX group is during DRX Active Time of other DRX groups of the terminal device, the terminal device still monitors the first WUS at the WUS monitoring occasion corresponding to the first DRX group;

as another example, if the WUS monitoring occasion corresponding to the first DRX group is not in the DRX Active Time period of any DRX group of the terminal device, the UE monitors the first WUS at the WUS monitoring occasion corresponding to the first DRX group.

For each DRX group, if the terminal device monitors and detects a WUS in the WUS monitoring occasion corresponding to the DRX group, the terminal device may determine, according to an indication of the WUS, whether an SCell activated in the SCell associated with the DRX group is a dormant behavior or a non-dormant behavior.

In some embodiments, the first WUS is configured to indicate that the behavior of the terminal device on all active secondary cells associated with the first DRX group is the target behavior, that is, the first WUS only needs to indicate one target behavior, which is denoted as embodiment 1.

In other words, the WUS corresponding to each DRX group may be used to indicate the behavior of the terminal device on all active secondary cells associated with the DRX group, and the behaviors of all active secondary cells associated with the DRX group are consistent, i.e., are both dormancy behaviors or both non-dormancy behaviors.

As an example, the first WUS includes 1 bit of indication information for indicating whether the target behavior is a dormant behavior or a non-dormant behavior, i.e., the behavior on all active secondary cells associated with the first DRX group switches to the target behavior.

Specifically, the terminal device may control, according to an indication of a first WUS corresponding to the first DRX group, behaviors of all activated scells in the scells associated with the first DRX group, where a specific handover behavior is described by taking an example that the activated scells associated with the first DRX group include the first SCell and the second SCell.

Case 1: and the first WUS corresponding to the first DRX group indicates a dormant behavior, and the terminal equipment switches the behaviors on all activated SCells in the SCells associated with the first DRX group into dormant behaviors:

1. maintaining the dormancy behavior of the terminal device on the first SCell unchanged if the behavior of the terminal device on the first SCell before the first WUS is received is dormancy behavior.

2. If the behaviour of the terminal device on the first SCell before the first WUS is a non-behavior, switching the behaviour of the terminal device on the second SCell from the non-behavior to the behavior.

Case 2: and the first WUS corresponding to the first DRX group indicates non-dormant behaviors, and the terminal equipment switches the behaviors on all activated SCells in the SCells associated with the first DRX group into the non-dormant behaviors:

1. and if the behavior of the terminal device on the first SCell before the first WUS is received is a dormant behavior, switching the behavior of the terminal device on the first SCell from the dormant behavior to a non-dormant behavior.

2. Maintaining the non-dormany behavior of the terminal device on the second SCell unchanged if the behavior of the terminal device on the second SCell before receiving the first WUS is non-dormany behavior.

In other embodiments, if the first WUS corresponding to the first DRX group does not include a behavior indication of the SCell, the behavior on the SCell is maintained for all activated scells among the scells associated with the first DRX group. For example, if the behaviour of the terminal device on the second SCell before the first WUS is received is non-downlink behaviour, then the non-downlink behaviour of the terminal device on the second SCell is maintained unchanged.

It should be understood that, in the embodiment of the present application, the dormant behavior on the SCell may refer to that the terminal device does not monitor the PDCCH on the SCell, but the terminal device may also maintain a configured behavior on the SCell, such as Channel State Information (CSI) measurement, AGC, or beam management.

Referring to fig. 4, the manner of WUS indication and switching of the behavior of the terminal device on the secondary cell in embodiment 1 of the present application will be described by taking the insomnia-type behavior as the therapy behavior or non-therapy behavior as an example, but the present application is not limited thereto.

In this embodiment of the present application, a terminal device may receive Radio Resource Control (RRC) configuration information of a network device, and optionally, the RRC configuration information may include at least one of the following information:

a, DRX parameters of the DRX group.

As an example, the network device configures 2 DRX groups for the terminal device, denoted as DRX group1 and DRX group2, where DRX group1 is used for an operating Frequency band (FR) 1, DRX group2 is used for FR2, and each DRX group corresponds to a set of DRX parameter configurations.

b, cell configuration information.

As an example, the network device configures the PCell of the terminal device to be cell 0(cell0), and simultaneously configures the terminal device with 5 scells, including SCell 1-SCell 5. Wherein, PCell, SCell 1 and SCell2 correspond to FR1, SCell3, SCell4 and SCell5 correspond to FR2, that is, the cell associated with DRX group1 includes PCell, SCell 1 and SCell2, and the cell associated with DRX group2 includes SCell3, SCell4 and SCell 5.

c, WUS configuration.

The network device allocates and configures corresponding WUS monitoring sessions to the DRX group1 and DRX group 2. As an example, both WUS monitoring sessions of DRX group1 and DRX group2 are located in PCell.

For DRX group1, the terminal device monitors WUS1 at the WUS1monitoring occasion corresponding to DRX group1, and if WUS1 is detected, the terminal device may be controlled to act on the activated scells (SCell 1 and SCell2) associated with DRX group1 according to the instructions of WUS 1.

For example, if WUS1 indicates that the terminal device's behavior on SCell is non-dormancy behavior, the terminal device may monitor PDCCH on SCell 1 and SCell2 when the terminal device's behavior is both non-dormancy behavior and further on SCell 1 and SCell 2.

For another example, if WUS1 indicates that the behavior of the terminal device on SCell is a dormancy behavior, then the behavior of the terminal device on SCell 1 and SCell2 is both dormancy behavior, i.e., the terminal device does not monitor PDCCH on SCell 1 and SCell 2.

Similarly, for DRX group2, the terminal device monitors WUS2 at the WUS2monitoring occasion corresponding to DRX group2, and if detecting WUS2, the terminal device may be controlled to act on the activated SCell (i.e. SCell3, SCell4, and SCell 5) associated with DRX group2 according to the indication of WUS2, which is not described herein for brevity.

In the example of fig. 4, for DRX group1, WUS1 indicates that the terminal device's behavior on SCell is non-dormancy behavior, then the terminal device's behavior on SCell 1 and SCell2 switches to non-dormancy behavior after the start time of the DRX cycle, further, if the terminal device receives PDCCH on PCell during the DRX cycle, if the PDCCH indicates that the behavior on SCell 1 is dormancy behavior, the terminal device's behavior on SCell 1 switches from non-dormancy behavior to dormancy behavior, and for SCell2, the terminal device's behavior on SCell2 maintains non-dormancy behavior before the start time of the next DRX cycle.

If the terminal device receives another WUS1 indicating that the terminal device's behavior on SCell is dormancy behavior before the turn-on time of the next DRX cycle, then the terminal device's behavior on both SCell 1 and SCell2 switches to dormancy behavior after the turn-on time of the next DRX cycle.

For DRX group2, WUS2 indicates that the terminal device's behavior on SCell is dormancy behavior, then the terminal device's behavior on SCell3, SCell4, and SCell5 switches to dormancy behavior after the start time of the DRX cycle.

Further, during this DRX cycle, if the terminal device receives PDCCH on PCell, if the PDCCH indicates that the terminal device's behavior on SCell3 is non-downlink behavior, then the terminal device's behavior on SCell3 is switched from downlink behavior to non-downlink behavior, for SCell4 and SCell5, the terminal device maintains downlink behavior on SCell4 and SCell5 until the on-time of the next DRX cycle.

If the terminal device receives another WUS2 indicating that the terminal device's behavior on SCell is non-dormant before the on time for the next DRX cycle, the terminal device's behavior on SCell3, SCell4, and SCell5 switches to non-dormant after the on time for the next DRX cycle.

In other embodiments of the present application, the first WUS is configured to indicate a target behavior of the terminal device on each of the active secondary cells associated with the first DRX group, as embodiment 2.

That is, the WUS corresponding to each DRX group may be used to indicate the behavior of the terminal device on each of all active secondary cells associated with the DRX group, and the behavior on each of the active secondary cells associated with the DRX group may be the same or different.

As an example, a bitmap may be used to indicate the behavior on each active secondary cell associated with a DRX group.

For example, for a first WUS corresponding to a first DRX group, the first WUS may include a first bit map, each bit of the first bit map corresponding to one active secondary cell associated with the first DRX group, the each bit indicating whether a target behavior of the corresponding active secondary cell is dormant or non-dormant behavior.

Specifically, the terminal device may control, according to an indication of a first WUS corresponding to the first DRX group, a behavior of each activated SCell in the scells associated with the first DRX group, where a specific handover behavior is described by taking an example that the activated SCell associated with the first DRX group includes the first SCell.

For example, if a first WUS corresponding to the first DRX group indicates that the first SCell is dormancy behavior, and the behavior of the terminal device on the first SCell before the first WUS is received is dormancy behavior, the dormancy behavior of the terminal device on the first SCell is maintained;

for another example, if the first WUS corresponding to the first DRX group indicates that the first SCell is dormant, and the behavior of the terminal device on the first SCell before the first WUS is received is non-dormant, the behavior of the terminal device on the second SCell is switched from non-dormant to dormant.

In other embodiments, if the first WUS corresponding to the first DRX group does not include a behavior indication for the first SCell, the terminal device maintains the behavior on the first SCell unchanged.

It should be understood that the above indication modes are only examples, and other indication modes derived from the indication modes provided by the embodiments of the present application also fall into the protection scope of the embodiments of the present application.

Fig. 5 below illustrates an example of how to instruct WUS and how to switch the behavior of a terminal device on a secondary cell in embodiment 2 of the present application, where the insomnia-related behavior is a dormancy behavior or a non-dormancy behavior, but the present application is not limited to this. It should be understood that DRX parameter configuration, cell configuration, WUS configuration, and the like in this embodiment refer to the embodiment shown in fig. 4, and are not described herein for brevity.

For DRX group1, the terminal device monitors WUS1 at the WUS1monitoring occasion corresponding to DRX group1, and if WUS1 is detected, the terminal device may control the behavior on the activated scells (SCell 1 and SCell2) associated with DRX group1 according to the instruction of WUS 1.

In the example of fig. 5, WUS1 indicates that the terminal device's behavior on SCell 1 and SCell2 is non-dormancy behavior, then the terminal device's behavior on SCell 1 and SCell2 switches to non-dormancy behavior after the activation time of the DRX cycle, further, if the terminal device receives PDCCH on PCell during the DRX cycle, if the PDCCH indicates that the behavior on SCell 1 is dormancy behavior, the terminal device's behavior on SCell 1 switches from non-dormancy behavior to dormancy behavior, and for SCell2, the terminal device's behavior on SCell2 maintains non-dormancy behavior before the activation time of the next DRX cycle.

If the terminal device receives another WUS1 indicating that the terminal device's behavior on SCell 1 and SCell2 is dormancy behavior and non-dormancy behavior, respectively, before the turn-on time of the next DRX cycle, the terminal device's behavior on SCell 1 switches to dormancy behavior and the behavior on SCell2 switches to non-dormancy behavior after the turn-on time of the next DRX cycle.

For DRX group2, the terminal device monitors WUS2 at the WUS2monitoring occasion corresponding to DRX group2, and if WUS2 is detected, the terminal device may be controlled to act on the activated scells (SCell 3, SCell4, and SCell 5) associated with DRX group2 according to the instructions of WUS 2.

In the example of fig. 5, WUS2 indicates that the terminal device's behavior on SCell3, SCell4, and SCell5 is dormancy behavior, non-dormancy behavior, and dormancy behavior, respectively, then the terminal device's behavior on SCell3, SCell4, and SCell5 switches to dormancy behavior, non-dormancy behavior, and dormancy behavior, respectively, after the activation time of the DRX cycle, further if the terminal device receives PDCCH on PCell during the DRX cycle, if the PDCCH indicates that the behavior on SCell3 is non-dormancy behavior, the terminal device's behavior on SCell3 switches from dormancy behavior to non-dormancy behavior, and for SCell4 and SCell5, the terminal device's behavior on SCell4 and SCell5 remains unchanged until the activation time of the next DRX cycle.

If the terminal device receives another WUS2 indicating that the terminal device's behavior on SCell3, SCell4, and SCell5 is non-dormancy behavior, and dormancy behavior, respectively, before the turn-on time of the next DRX cycle, the terminal device's behavior on SCell3, SCell4, and SCell5 switches to non-dormancy behavior, and dormancy behavior, respectively, after the turn-on time of the next DRX cycle.

It can be seen from the above embodiments that the signaling overhead of the indication scheme WUS in embodiment 1 is smaller, and the indication scheme in embodiment 2 can implement flexible indication of a behavior on each SCell, and the indication granularity is finer, which is beneficial to implementing flexible adjustment of a behavior on each SCell, and further reduces the power consumption of the terminal device.
