The technical scheme provided by the embodiment of the application is described in detail through specific embodiments and application scenes thereof with reference to the accompanying drawings.

As shown in fig. 2, a flowchart of a method 200 for controlling a secondary cell according to an exemplary embodiment of the present application is provided, which may be applied to, but not limited to, a terminal, and may be specifically executed by hardware and/or software installed in the terminal. The method at least comprises the following steps.

S210, monitoring dormancy indication information from a target node.

Wherein the target node may be MN and/or SN, etc.

S220, controlling the target dormancy group to enter or leave dormancy according to the dormancy indication information.

Wherein, the target sleep Group (dormant Group) may include a target PSCell and/or a target SCG.

It should be understood that under the DC architecture, each Cell group includes one Special Cell (SPCell), where the Special Cell in the MCG is called a Primary Cell (PCell), and the Special Cell in the SCG is called a Primary secondary Cell (PSCell, primary Secondary Cell). In addition, in one cell group, the SPCell uses a primary carrier, while other secondary cells use secondary carriers, and resource scheduling within one cell group is performed by the SPCell. That is, taking SCG as an example, PSCell uses a primary carrier, is responsible for scheduling resources in SCG, and scells other than PSCell in SCG use a secondary carrier.

In this case, the target SCG may be an SCG to which the target PSCell belongs.

In one implementation, depending on the target Dormancy Group (dormant Group), the implementation of S220 may have the following cases:

(1) In the case that the target sleep group includes the target SCG, the terminal may control the SCell and the PSCell (i.e., the target PSCell) included in the target SCG to enter sleep (Entering Dormancy) or leave sleep (Leaving sleep) according to the sleep indication information.

(2) In the case that the target sleep group includes a target PSCell, the terminal may control the target PSCell and an SCell belonging to the same sleep group as the target PSCell to enter or leave sleep according to the sleep indication information.

(3) And when the target dormancy group comprises a target PSCell and a target SCG, the terminal controls the SCell and the PSCell (namely the target PSCell) which are included in the target SCG to enter dormancy or leave dormancy according to the dormancy indication information.

In another implementation, the target dormancy group and the target node may have a correspondence. For example, in the case where the target sleep group is a first sleep group, a target node having a correspondence with the first sleep group may include MN and SN; in the case that the target sleep group is a second sleep group, the target node having a correspondence with the second sleep group may include a MN; in the case that the target sleep group is a third sleep group, the target node having a correspondence with the third sleep group may include SN.

In the method for controlling the secondary cell provided by the embodiment, the terminal monitors sleep indication information from the target node and controls the target sleep group to enter or leave sleep according to the sleep indication information, wherein the target sleep group comprises the target PSCell and/or the target SCG, so that on one hand, suspension of the SCG can be realized by controlling the sleep of the target PSCell and/or the target SCG, and when the terminal is in a scene of continuous low data volume transmission and the like, the power consumption of the terminal is reduced by suspending the target SCG. On the other hand, when the terminal is in low data volume transmission for a long time, the embodiment temporarily suspends the target SCG instead of directly deleting or releasing the target SCG, so that when the terminal resumes high data volume transmission, the target SCG can be quickly recovered again by controlling the target PSCell and/or the target SCG to leave dormancy, the flexibility of SCG control is effectively improved, and the communication performance of the terminal is ensured.

As shown in fig. 3a, a flowchart of a method 300 for controlling a secondary cell according to an exemplary embodiment of the present application is provided, which may be applied to, but not limited to, a terminal, and may be specifically executed by hardware and/or software installed in the terminal. The method at least comprises the following steps.

S310, monitoring dormancy indication information from a target node.

In addition to the detailed description of S210, in a specific implementation manner of S310, in one possible implementation manner, the sleep indication information may be transmitted through a wake-up signal (WUS) and/or downlink control information (Downlink Control Information, DCI).

Optionally the wake-up signal may comprise any of the following:

(1) PCell wake-up signal.

(2) Wake-up signal in PSCell non-sleep state.

(3) Wake-up signal in PSCell sleep state.

The wake-up signal in the PSCell sleep state may be the same as or different from the wake-up signal in the PSCell non-sleep state. Alternatively, the signal morphology of the aforementioned wake-up signal may be WUS physical downlink control channel (Physical downlink control channel, PDCCH) or WUS sequence. In one implementation, the wake-up signal may include 1bit (bit) or multiple bits to indicate the sleep indication information.

Further, at least one predetermined bit for indication of the sleep indication information may be included in the DCI. The predetermined bit may be a new bit in the DCI or an existing bit in the DCI, and the predetermined bit may be 1bit or more bits, such as DCI formats (formats) 0-1and 1-1.

In another implementation manner, the sleep indication information is obtained by monitoring on the target PSCell by the terminal when the sleep indication information is used to instruct the terminal to control the target sleep group to leave sleep. In other words, during the period that the target PSCell or the target SCG goes into sleep, the terminal may monitor sleep indication information (such as a wake-up signal) on the target PSCell in the sleep state, and control the target PSCell or the target SCG to transition from the sleep state (dorman) to the Non-sleep state (Non-dorman) according to the sleep indication information.

Optionally, after the target PSCell or target SCG goes to sleep, the behavior of the terminal may include at least one of:

(1) Monitor WUS PDCCH on target PSCell dormant BWP.

(2) The target PSCell WUS sequence is listened to.

It can be appreciated that the WUS PDCCH, WUS sequence described above is two different signal forms of sleep indication information.

In one implementation, the sleep indication information may include a radio network temporary identifier (Radio Network Tempory Identity, RNTI), where the RNTI is different from RNTIs in other WUS, DCI, etc. signals, and the RNTI in the sleep indication information is used to perform cyclic redundancy check (Cyclic redundancy check, CRC) scrambling on the sleep indication information.

S320, controlling the target dormancy group to enter or leave dormancy according to the dormancy indication information.

In addition to the detailed description of S220, in a possible implementation manner, as shown in fig. 3b, in a specific implementation manner of S320, controlling the target sleep group to enter sleep according to the sleep indication information as described in S320 may be implemented through S330 or S340.

S330, controlling the terminal to enter a target PSCell dormant bandwidth part.

It should be understood that, in this step, the control terminal enters the target PSCell dormant Bandwidth Part (BWP), and the control terminal enters the dormant state as described in S340 can achieve the same or corresponding technical purpose.

And S340, controlling the target PScell of the terminal to enter sleep.

Corresponding to S330, the control of the target PSCell of the terminal to enter sleep in this step may achieve the same or corresponding technical purpose as the control of the terminal to enter the target PSCell sleep bandwidth described in S330.

In one implementation, it is considered that one target SCG may include one target PSCell and a plurality of scells, based on which one target sleep group may include only the target PSCell, or may include the target PSCell and at least one SCell.

In this case, when the target PSCell goes dormant, the state of the SCell in the target SCG to which the target PSCell belongs is at least one of the following:

(1) And the target SCell which is in the same target dormancy group with the target PSCell enters dormancy. It is understood that the target PSCell and the target SCell are both in an active state.

(2) And the other SCell except the target SCell in the target SCG is in a deactivated state.

(3) The scells in the target SCG are all in a deactivated state.

In another possible implementation manner, as shown in fig. 3b, according to the sleep indication information, as described in S320, controlling the target sleep group to leave sleep may be implemented through S350 or S360.

And S350, controlling the terminal to leave the target PSCell dormant BWP.

S360, controlling the target PScell of the terminal to leave sleep.

The specific implementation manners of S350 and S360 are similar to those described in S330 and S340 for controlling the target sleep group to enter sleep according to the sleep indication information, and are not described herein.

Furthermore, it should be noted that, after the target sleep group (such as the target PSCell or the target SCG) leaves sleep, the behavior of the terminal may include, but is not limited to, at least one of the following:

(1) Downlink shared channel (Downlink Shared Channel, DL-SCH) information is received on BWP.

(2) Sounding reference signal (Sounding Reference Signal, SRS) information is transmitted on BWP.

(3) Uplink shared channel (Uplink Shared Channel, UL-SCH) information is transmitted on BWP.

(4) PUCCH information is transmitted on BWP.

In the method for controlling the secondary cell according to the embodiment, when the terminal controls the target sleep group to enter or leave sleep according to the monitored sleep indication information, the terminal may be controlled to enter or leave PSCell sleep BWP (or control the target PSCell of the terminal to enter or leave sleep), so as to suspend SCG.

As shown in fig. 4, a flowchart of a method 400 for controlling a secondary cell according to an exemplary embodiment of the present application is provided, which may be applied to, but not limited to, a terminal, and may be specifically executed by hardware and/or software installed in the terminal. The method at least comprises the following steps.

S410, monitoring dormancy indication information from a target node.

In addition to the corresponding descriptions of the foregoing method embodiments, as a possible implementation manner, the implementation process of monitoring the sleep indication information from the target node in S410 may be different according to the target node, and is described below with reference to different examples.

In example 1, where the target node includes a primary node and a secondary node, listening for sleep indication information from the target node described in S410 includes: monitoring first dormancy indication information from a PSCell, wherein the first dormancy indication information is used for indicating the target dormancy group to enter dormancy; and/or monitor second sleep indication information from the PCell, where the second sleep indication information is used to indicate the target sleep group to leave sleep.

In example 2, in the case that the target node includes a primary node and a secondary node, listening for sleep indication information from the target node described in S410 may further include: monitoring first dormancy indication information from a PCell, wherein the first dormancy indication information is used for indicating the target dormancy group to enter dormancy; and/or monitor second sleep indication information from the PSCell, where the second sleep indication information is used to indicate the target sleep group to leave sleep.

Example 3, where the target node includes a master node, listening for sleep indication information from the target node as described in S310 includes: and monitoring sleep indication information from the PCell, wherein the sleep indication information is used for indicating the target sleep group to enter or leave sleep.

Example 4, where the target node includes a secondary node, listening for sleep indication information from the target node described in S310 includes: and monitoring sleep indication information from the PSCell, wherein the sleep indication information is used for indicating the target sleep group to enter or leave sleep.

It will be appreciated that the actual implementation of S410 may be any of the foregoing examples 1 to 4, and the present embodiment is not limited herein.

In addition to the foregoing detailed description of the method embodiments, in one implementation manner, the implementation process of S420 is different according to the target sleep group, and is described below with reference to different examples.

In example 1, assuming that the target sleep group is a first sleep group, and the target node includes a primary node and a secondary node, the implementation process for controlling the target sleep group to enter or leave sleep according to the sleep indication information described in S420 may include: controlling the first sleep group to enter sleep under the condition that the first sleep indication information is monitored; and/or controlling the first sleep group to leave sleep under the condition that the second sleep indication information is monitored.

Wherein, optionally, the first sleep indication information may include: PSCell WUS PDCCH information, PSCell DCI, etc., the second sleep indication information may include: PCell WUS PDCCH information, PCell DCI, etc.

In one implementation manner, in a case where the target sleep group includes a PSCell and the terminal listens for the first sleep indication information (such as PSCell dormancy PDCCH indication information) on the PSCell, the implementation process for controlling the target sleep group to enter sleep in S420 may include: and controlling the terminal to enter a target PSCell dormant bandwidth part or controlling the target PSCell of the terminal to enter dormancy, thereby realizing suspension of SCG and reducing power consumption of the terminal.

In another implementation manner, in the case where the target sleep group includes a PSCell and the terminal listens to the second sleep indication information (e.g., the dormancy PDCCH indication information) on the PCell, the implementation process for controlling the target sleep group to leave sleep in S420 may include: and controlling the terminal to leave the sleep bandwidth part of the target PSCell, or controlling the target PSCell of the terminal to leave the sleep, so as to realize the recovery of the target SCG and ensure the communication performance of the terminal.

In example 2, assuming that the target sleep group is the second sleep group and the target node includes the master node, the implementation process for controlling the target sleep group to enter or leave sleep according to the sleep indication information described in S420 may include: and controlling the second sleep group to enter or leave sleep under the condition that the third sleep indication information is monitored.

Wherein the third sleep indication information is sleep indication information from the PCell. The third sleep indication information may include: PCell WUS PDCCH information, PCell DCI, etc.

In addition, the specific implementation manner of example 2 is similar to that of example 1 corresponding to S420, and will not be described here again. It should be noted that, unlike example 1, in the case where the target node includes the master node, the third sleep indication information for indicating that the second sleep group enters or leaves sleep is all the terminal listens on the PCell.

In example 3, assuming that the target sleep group is a third sleep group and the target node includes a secondary node, the implementation process of controlling the target sleep group to enter or leave sleep according to the sleep indication information in S420 may control the third sleep group to enter or leave sleep by monitoring the fourth sleep indication information. .

Wherein the fourth sleep indication information is sleep indication information from the PSCell, and the fourth sleep indication information may include: PSCell WUS PDCCH information, PSCell DCI, etc.

In addition, the specific implementation manner of this example 3 is similar to that of the foregoing example 1 corresponding to SS420, and will not be described here again. It should be noted that, unlike example 1, in the case where the target node includes the secondary node, the fourth sleep indication information for indicating that the third sleep group enters or leaves sleep is all obtained by the terminal listening on the PSCell.

In the method for controlling the secondary cell provided by the embodiment, the terminal controls the target dormancy group to enter or leave dormancy according to the corresponding relation between the target dormancy group and the target node and the dormancy indication information from different target nodes, thereby realizing the suspension or restoration of the SCG.
