The method can be applied to but not limited to a terminal, and can be specifically executed by hardware and/or software installed in the terminal. The method includes at least the following steps.

S210, monitor the sleep indication information from the target node.

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

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

Wherein, the target dormancy group (Dormancy Group) may include the target PSCell and/or the target SCG.

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

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

In an implementation manner, according to the difference of the target dormancy group (Dormancy Group), the implementation manner of the aforementioned S220 may have the following situations:

(1) In the case where the target dormancy group includes the target SCG, the terminal can control the SCell and PSCell (that is, the target PSCell) included in the target SCG to enter dormancy (Entering Dormancy) or leave dormancy ( Leaving dormancy).

(2) When the target dormancy group includes a target PSCell, the terminal may control the target PSCell and the SCells belonging to the same dormancy group as the target PSCell to enter or leave dormancy according to the dormancy indication information.

(3) When the target dormancy group includes a target PSCell and a target SCG, the terminal controls the SCell and PSCell (that is, the target PSCell) included in the target SCG to enter or leave dormancy according to the dormancy indication information.

In another implementation manner, there may be a corresponding relationship between the target sleep group and the target node. For example, in the case that the target dormancy group is the first dormancy group, the target nodes that have a corresponding relationship with the first dormancy group may include MN and SN; in the case that the target dormancy group is the second dormancy group , the target node having a corresponding relationship with the second dormancy group may include MN; in the case that the target dormancy group is the third dormancy group, the target node having a corresponding relationship with the third dormancy group may include SN.

In the method for controlling a secondary cell provided in this embodiment, the terminal monitors the 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 includes the target PSCell and/or target SCG, thus, on the one hand, it is possible to suspend the SCG by controlling the dormancy of the target PSCell and/or the target SCG, so that when the terminal is in scenarios such as continuous low data volume transmission, the Hang it up to reduce the power consumption of the terminal. On the other hand, when the terminal is in low data volume transmission for a long time, this 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 rapid recovery of the target SCG is realized by controlling the target PSCell and/or the target SCG to leave dormancy again, which effectively improves the flexibility of the SCG control and ensures the communication performance of the terminal.

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

(1) PCell wake-up signal.

(2) The wake-up signal in the non-sleep state of the PSCell.

(3) The wake-up signal in the sleep state of PSCell.

The wake-up signal in the sleep state of the PSCell and the wake-up signal in the non-sleep state of the PSCell may be the same or different. Optionally, the signal form of the aforementioned wake-up signal may be a WUS physical downlink control channel (Physical downlink control channel, PDCCH) or a WUS sequence. In an implementation manner, the wake-up signal may include 1 bit or multiple bits to indicate the sleep indication information.

The predetermined bits may be newly added bits in DCI, or may be existing bits in DCI, and the predetermined bits may be 1 bit or multiple bits, such as DCI formats (formats) 0- 1 and 1-1.

In another implementation manner, when the dormancy indication information is used to instruct the terminal to control the target dormancy group to leave dormancy, the dormancy indication information is obtained by the terminal listening on the target PSCell. In other words, when the target PSCell or the target SCG enters dormancy, the terminal can monitor the dormancy indication information (such as a wake-up signal, etc.) on the target PSCell in the dormant state, and control the target PSCell or the target SCG from the dormant indication information according to the dormancy indication information. The dormant state (dormant) transitions to a non-dormant state (Non-dormant).

It can be realized by S330 or S340.

S330: Control the terminal to enter the sleep bandwidth part of the target PSCell.

It should be understood that controlling the terminal to enter the sleep bandwidth part (Bandwidth Part, BWP) of the target PSCell in this step can achieve the same or corresponding technical purpose as the control of the target PSCell of the terminal described in S340 to enter sleep.

S340, controlling the target PSCell of the terminal to enter dormancy.

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

In an implementation manner, considering that a target SCG may include a target PSCell and multiple SCells, based on this, a 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 enters dormancy, the state of the SCell in the target SCG to which the target PSCell belongs is at least one of the following:

(1) The target SCell that is in the same target dormancy group as the target PSCell enters dormancy. It can be understood that both the target PSCell and the target SCell are in an active state.

(2) Other SCells in the target SCG except the target SCell are in a deactivated state.

(3) All SCells in the target SCG are in a deactivated state.

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

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

S360, controlling the target PSCell of the terminal to leave dormancy.

The specific implementation manners of the foregoing S350 and S360 are similar to the control of the target dormancy group to enter dormancy according to the dormancy instruction information described in the foregoing S330 and S340, and details are not described herein again.

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

(1) Receive Downlink Shared Channel (DL-SCH) information on the BWP.

(2) Sending sounding reference signal (Sounding Reference Signal, SRS) information on the BWP.

(3) Send uplink shared channel (Uplink Shared Channel, UL-SCH) information on the BWP.

(4) Send PUCCH information on the BWP.
