Description

Method, terminal and network side equipment for controlling secondary cell

Technical Field

The application belongs to the technical field of wireless communication, and particularly relates to a method, a terminal and a network side device for controlling a secondary cell.

Background

In a fifth Generation (5Generation, 5G) mobile communication system, a terminal (User Equipment, UE) may adopt a Dual Connectivity (DC) architecture, which may provide resources of two network nodes (access network elements) for the UE, one network node being called a Master Node (MN) and the other network node being called a Secondary Node (SN).

For each network node, the UE may be configured with a series of serving cells, also referred to as cell groups (CA), controlled by the network node using Carrier Aggregation. Among them, a Cell Group controlled by MN is called Master Cell Group (MCG), and a Cell Group controlled by SN is called Secondary Cell Group (SCG). In some scenarios, such as when the UE is in a low data volume transmission scenario, the SCG may be in a suspend (suspend) state to reduce power consumption of the UE.

However, there is no control scheme that can reasonably control the execution suspension flow of the SCG, and the power consumption of the UE can be further reduced.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

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

S210, monitoring the dormancy indication information from the target node.

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

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

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

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

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

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

(1) in the case that the target dormant group includes the target SCG, the terminal may control, according to the Dormancy indication information, the SCell included in the target SCG, the PSCell (i.e., the target PSCell), and both of them to go to Dormancy (ending dormant) or leave Dormancy (Leaving dormant).

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

(3) And under the condition that the target dormancy group comprises the target PSCell and the target SCG, the terminal controls the SCell and the PSCell (namely the target PSCell) in the target SCG to enter the dormancy or leave the dormancy according to the dormancy indication information.

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

In the method for controlling a secondary cell provided in this embodiment, a terminal monitors dormancy indication information from a target node and controls a target dormancy group to enter or leave a dormancy according to the dormancy indication information, where the target dormancy group includes a target PSCell and/or a target SCG, and thus, on one hand, suspension of the SCG can be achieved by controlling dormancy of the target PSCell and/or the target SCG, so that power consumption of the terminal is reduced by suspending the target SCG when the terminal is in a scenario of continuous low data volume transmission or the like. On the other hand, when the terminal is in low data volume transmission for a long time, the target SCG is temporarily suspended, rather than being directly deleted or released, so that when the terminal resumes high data volume transmission, the target SCG can be quickly resumed by controlling the target PSCell and/or the target SCG to leave the sleep again, thereby effectively improving the flexibility of SCG control and ensuring the communication performance of the terminal.

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

S310, the dormancy indication information from the target node is monitored.

In addition to the detailed description of S210, in a possible implementation manner, the sleep indication Information may be transmitted through a Wake Up Signal (WUS) and/or Downlink Control Information (DCI).

Optionally, the wake-up signal may include any one of the following:

(1) a PCell wake-up signal.

(2) A wake-up signal in a 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 form of the wake-up signal may be a Physical Downlink Control Channel (PDCCH) or a WUS sequence. In one implementation, the wake-up signal may include 1bit (bit) or more bits to indicate the sleep indication information.

In addition, at least one predetermined bit may be included in the DCI, and the at least one predetermined bit is used for the indication of the sleep indication information. The predetermined bits may be newly added bits in the DCI or existing bits in the DCI, and the predetermined bits may be 1bit or multiple bits, such as DCI formats (formats)0-1and 1-1.

In another implementation manner, when the dormancy indication information is used to indicate the terminal to control the target dormancy group to leave dormancy, the dormancy indication information is obtained by the terminal by monitoring on the target PSCell. In other words, during the period that the target PSCell or target SCG enters into sleep, the terminal may listen to sleep indication information (e.g., wake-up signal, etc.) on the target PSCell in the sleep state, and control the target PSCell or target SCG to transition from the sleep state (dormant) to the Non-sleep state (Non-dormant) according to the sleep indication information.

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

(1) and monitoring the WUS PDCCH on the target PSCell dormant BWP.

(2) And monitoring a target PSCell WUS sequence.

It is understood that the WUS PDCCH and WUS sequence described above are two different signal forms of sleep indication information.

In one implementation, the sleep indication information may include a Radio Network Temporary Identity (RNTI), where the RNTI is different from RNTIs in other WUS, DCI, and other signals, and the RNTI in the sleep indication information is used to perform Cyclic Redundancy Check (CRC) scrambling on the sleep indication information.

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

In addition to the detailed description referring to the foregoing S220, in a possible implementation form of S320, as shown in fig. 3b, the step of controlling the target sleep group to go to sleep according to the sleep indication information in S320 may be implemented by S330 or S340.

S330, controlling the terminal to enter the sleep bandwidth part of the target PSCell.

It should be understood that the controlling of the terminal to enter the target PSCell dormancy Bandwidth Part (BWP) in this step can achieve the same or corresponding technical objectives as the controlling of the target PSCell of the terminal to enter the dormancy in S340.

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

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

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

In this case, when the target PSCell enters into sleep, the state of the SCell in the target SCG to which the target PSCell belongs is at least one of:

(1) and enabling the target SCell which is in the same target sleep group with the target PSCell to enter the sleep mode. It is understood that the target PSCell and the target SCell are both in an active state.

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

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

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

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

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

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

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

(1) downlink Shared Channel (DL-SCH) information is received on BWP.

(2) Sounding Reference Signal (SRS) information is sent on BWP.

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

(4) The PUCCH information is transmitted on BWP.

In the method for controlling a secondary cell provided in this embodiment, when the terminal controls the target dormant group to enter or leave the dormant state according to the monitored dormancy indication information, the terminal may be controlled to enter or leave the PSCell dormancy BWP (or the target PSCell of the terminal is controlled to enter or leave the dormant state), so as to suspend the 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 applicable to, but not limited to, a terminal, and may be specifically executed by hardware and/or software installed in the terminal. The method comprises at least the following steps.

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

Example 1, in a case that the target node includes a primary node and a secondary node, the listening for the sleep indication information from the target node 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 monitoring second dormancy indication information from a PCell, wherein the second dormancy indication information is used for indicating that the target dormancy group leaves dormancy.

Example 2, in a case that the target node includes a primary node and a secondary node, the listening for the sleep indication information from the target node 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 monitoring second dormancy indication information from the PSCell, wherein the second dormancy indication information is used for indicating that the target dormancy group leaves dormancy.

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

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

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

And S420, controlling the target sleep group to enter or leave the sleep according to the sleep indication information.

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

Example 1, assuming that the target sleeping group is a first sleeping group, and the target node includes a primary node and a secondary node, the implementation process of controlling the target sleeping group to enter or leave the sleeping mode according to the sleeping indication information in S420 may include: under the condition of monitoring first dormancy indication information, controlling the first dormancy group to enter dormancy; and/or controlling the first sleep group to leave the sleep mode under the condition of monitoring second sleep indication information.

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

In one implementation, in a case that the target dormant group includes a PSCell and the terminal monitors first dormancy indication information (e.g., PSCell downlink indication information) on the PSCell, the implementation process of controlling the target dormant group to go to dormancy in S420 may include: and controlling the terminal to enter a target PSCell dormancy bandwidth part, or controlling the target PSCell of the terminal to enter dormancy, so that the SCG is suspended, and the power consumption of the terminal is reduced.

In another implementation manner, in the case that the target dormant group includes a PSCell and the terminal monitors second dormancy indication information (e.g., dormant PDCCH indication information) on a PCell, the implementation process of controlling the target dormant group to leave the dormant in S420 may include: and controlling the terminal to leave the target PSCell dormancy bandwidth part, or controlling the target PSCell of the terminal to leave the dormancy, so that the target SCG is restored, and the communication performance of the terminal is ensured.

Example 2, assuming that the target sleeping group is the second sleeping group and the target node includes the master node, the implementation process of controlling the target sleeping group to enter or leave the sleeping according to the sleeping indication information in S420 may include: and controlling the second sleep group to enter or leave the sleep mode under the condition of monitoring third sleep indication information.

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

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

Example 3, assuming that the target sleeping group is a third sleeping group and the target node includes a secondary node, the implementation process of controlling the target sleeping group to enter or leave the sleeping state according to the sleeping indication information in S420 may be implemented by controlling the third sleeping group to enter or leave the sleeping state when a fourth sleeping indication information is monitored. .

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

In addition, the specific implementation form of this example 3 is similar to example 1 corresponding to the aforementioned SS420, and is not described again here. 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 the sleep is all listened to by the terminal on the PSCell.
