However, the following description describes a New Radio (NR) system for purposes of example, and NR terminology is used in much of the description below, although the techniques may also be applied to applications other than NR system applications, such as 6 th generation (6 th generation)^thGeneration, 6G) communication system.

Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable. The wireless communication system comprises a terminal 11 and a network node 12. Wherein, the terminal 11 may also be called as a terminal Device or a User Equipment (UE), the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer) or a notebook Computer, a Personal Digital Assistant (PDA), a palmtop Computer, a netbook, a super-Mobile Personal Computer (UMPC), a Mobile Internet Device (MID), a Wearable Device (Wearable Device) or a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), and other terminal side devices, the Wearable Device includes: bracelets, earphones, glasses and the like. It should be noted that the embodiment of the present application does not limit the specific type of the terminal 11. The network node 12 may be a Base Station or a core network, wherein the Base Station may be referred to as a node B, an evolved node B, an access Point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access Point, a WiFi node, a Transmit Receive Point (TRP), or some other suitable terminology in the field, and the Base Station is not limited to a specific technical vocabulary as long as the same technical effect is achieved.

For convenience of understanding, some contents related to the embodiments of the present application are described below:

one, Dual Connectivity (DC), Carrier Aggregation (CA).

The DC provides resources of two network nodes (e.g., access network elements) for the UE, where one network Node is called a Master Node (MN) and the other is called a Secondary Node (SN). At each network node, CA technology is used, i.e. a UE is configured with a series of serving cells, also called Cell groups (Cell groups), controlled by the node. The MN controls a Master Cell Group (MCG) and the SN controls a Secondary Cell Group (SCG). Each Cell group includes a Special Cell (SpCell) and a series of Secondary cells (Scell). In the MCG, the special Cell is called a Primary Cell (PCell), and in the SCG, the special Cell is called a Primary Secondary Cell (PSCell). The SpCell uses the primary carrier in one cell group, while the other secondary cells use the secondary carriers, and resource scheduling in one cell group is performed by the SpCell.

Secondly, SCG is suspended.

The UE can automatically suspend the SCG when judging that the SCG fails, and then report SCG failure information to the MN node.

The UE may suspend the SCG under the control of the network side, for example, when the UE transmits low data for a long time, the network side may suspend the SCG temporarily instead of deleting the SCG directly, and add the SCG back when transmitting large data. The SCG is suspended temporarily, so that the terminal can work in a more power-saving mode for a long time, and meanwhile, the SCG can be recovered quickly when a large amount of data is needed.

In the embodiment of the application, under the condition that the SCG of the terminal is in the suspended state, the terminal is disconnected from the SCG, so that the power consumption of the terminal can be saved; under the condition that the SCG of the terminal is recovered, the terminal and the SCG are reestablished to be connected, so that data transmission can be carried out through the SCG, and the data transmission rate is improved.

The SCG processing method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 2, fig. 2 is a flowchart of an SCG processing method provided in an embodiment of the present application. The SCG processing method of the embodiment of the application can be applied to the terminal. Further, the terminal may be in an RRC connected state and operate in a Dual Connectivity (MR-DC) mode, but is not limited thereto.

As shown in fig. 2, the SCG processing method applied to the terminal may include the steps of:

step 201, when the SCG of the terminal in the auxiliary cell group is in the suspended state, the SCG of the terminal is recovered by using the target resource.

In the embodiment of the present application, the target resource may include, but is not limited to, any one of the following: random Access Channel (RACH) resources; scheduling Request (SR) resources. In practical application, the target resource may be determined by network side configuration, protocol agreement, or a terminal, which is not limited in this application embodiment.

In a specific implementation, when the secondary cell group SCG of the terminal is in a suspended state, the recovering the SCG of the terminal using the target resource may include:

when the SCG of the auxiliary cell group of the terminal is in a suspended state, judging whether an SCG recovery condition is met; under the condition that the SCG recovery condition is met, recovering the SCG of the terminal by using a target resource;

wherein, satisfying the SCG recovery condition may include, but is not limited to, any one of the following:

the number of the data to be transmitted of the terminal is larger than a first threshold value;

and receiving first indication information, wherein the first indication information indicates the terminal to recover the SCG.

It should be noted that, in the embodiment of the present application, the trigger condition for triggering the SCG of the terminal to enter the suspend state is not limited. In specific implementation, the terminal may actively trigger the SCG to be placed in the suspended state, or may passively trigger the SCG to be placed in the suspended state.

Optionally, the trigger condition may include, but is not limited to, at least one of the following:

the SCG of the terminal fails;

and receiving second indication information, wherein the second indication information is used for indicating the terminal to place the SCG in a suspended state.

In the SCG processing method of this embodiment, when the secondary cell group SCG of the terminal is in a suspended state, the SCG of the terminal is recovered using a target resource; wherein the target resource comprises any one of: randomly accessing RACH resources; scheduling request SR resources. Therefore, the problem of recovery of the SCG after the SCG is suspended is solved, and the requirement of large-data-volume transmission of the terminal can be met.

In this embodiment of the present application, optionally, when the target resource is the RACH resource, the SCG of the terminal is recovered through an RACH procedure initiated on the RACH resource;

and under the condition that the target resource is the SR resource, the SCG of the terminal is recovered through an SR process initiated on the SR resource.

For ease of understanding, the detailed description is as follows:

in the case that the target resource is the RACH resource, the recovering the SCG of the terminal using the target resource may include:

initiating a RACH procedure on the RACH resource, the RACH procedure being used for requesting to recover the SCG of the terminal.

In a specific implementation, the embodiment of the present application does not limit the type of the RACH procedure, and optionally, the RACH procedure may be a 4-step RACH procedure or a 2-step RACH procedure.

In a case that the target resource is an SR resource, the recovering the SCG of the terminal using the target resource may include:

and initiating an SR process on the SR resource, wherein the SR process is used for requesting to recover the SCG of the terminal.

Therefore, by the method, the terminal can realize the quick recovery of the SCG through the RACH process or the SR process, and further can meet the requirement of large-data-volume transmission of the terminal.

In this embodiment of the present application, optionally, the recovering the SCG of the terminal by using the target resource includes:

sending an SCG recovery request message to a first network node using a target resource, the SCG recovery request message comprising at least one of: first identification information, second identification information or third identification information for indicating recovery of the SCG of the terminal; the terminal recovers the SCG reason value of the terminal;

the second identification information is obtained by a second network node by truncating the first identification information, and the third identification information is obtained by the terminal by truncating the first identification information.

In this optional embodiment, the terminal may request to restore the SCG of the terminal by sending an SCG restoration request message to the first network node. If the SCG of the terminal is recovered through the RACH procedure initiated on the RACH resource, for the 4-step RACH procedure, the SCG recovery request Message may be carried in a Message (Msg) 3 of the 4-step RACH procedure; for a 2-step RACH procedure, the SCG recovery request message may be carried in the MsgA of the 2-step RACH procedure. If the SCG of the terminal is recovered through the SR process initiated on the SR resource, the SCG recovery request message may be carried in the SR request message of the SR process.

In a specific implementation, the SCG recovery request message includes at least one of the following: first identification information, second identification information or third identification information for indicating recovery of the SCG of the terminal; and the terminal recovers the SCG reason value of the terminal.

The first identifier information, the second identifier information, and the third identifier information may all be used to indicate to recover the SCG of the terminal, that is, the first network node obtains any one of the first identifier information, the second identifier information, and the third identifier information, that is, it can know that the SCG recovery request message is used to request to recover the SCG of the terminal.

In this optional implementation, the second identification information is obtained by the second network node by truncating the first identification information, and the third identification information is obtained by the terminal by truncating the first identification information. That is, the second identification information and the third identification information may be obtained by truncating the first identification information, but the second identification information is generated by the second network node, and the third identification information is generated by the terminal. The second identification information and the third identification information may be regarded as identification information of a truncated format of the first identification information.

In a specific implementation, the first identification information and the second identification information may be configured by a second network node, and the third identification information may be autonomously generated by the terminal.

In a first implementation, the second network node may configure only the first identification information.

In a second implementation, the second network node may configure the first identification information and the second identification information at the same time.

Such as: in a Long Term Evolution (LTE) system, a second network node may configure only the first identification information; in the NR system, the second network node may configure the first identification information and the second identification information at the same time.

For the first implementation manner, the terminal may generate the third identification information; for the second implementation manner, since the second network node is configured with the second identification information, the terminal may generate the third identification information.

In this optional embodiment, if the SCG recovery request message includes the first identifier information, the second identifier information, or the third identifier information used for indicating to recover the SCG of the terminal, the terminal may determine that the SCG recovery request message carries that identifier information in the following manner:

detecting whether the number of bits carried by the SCG recovery request message is larger than a second threshold value;

under the condition that the number of bits carried by the SCG recovery request message is greater than the second threshold value, determining to carry the first identification information in the SCG recovery request message;

and when the number of bits that can be carried by the SCG recovery request message is less than or equal to the second threshold, deciding to carry the second identification information or the third identification information in the SCG recovery request message.

Further, detecting whether a second network node is configured with the second identification information or not under the condition that the number of bits that can be carried by the SCG recovery request message is less than or equal to the second threshold; if the second network node is configured with the second identification information, determining that the second identification information is carried in the SCG recovery request message; otherwise, the terminal generates the third identification information and determines that the third identification information is carried in the SCG recovery request message.

Therefore, in the above manner, the terminal may request to recover the SCG of the terminal by sending the SCG recovery request message to the first network node, thereby specifying a process of recovering the SCG of the terminal.

In this embodiment of the present application, optionally, after the sending, by using the target resource, the SCG recovery request message to the first network node, the method further includes:

receiving a response message of the SCG recovery request message sent by the first network node by using the target resource;

wherein the response message carries SCG configuration information, and the SCG configuration information at least includes primary and secondary cell PSCell configurations.

After receiving the SCG recovery request message sent by the terminal, the first network node may send a response message of the SCG recovery request message to the terminal, where the response message is used to indicate whether to allow the terminal to recover the SCG. If the SCG of the terminal is recovered through the RACH procedure initiated on the RACH resource, the response message may be carried in Msg4 of the 4-step RACH procedure for the 4-step RACH procedure; for a 2-step RACH procedure, the response message may be carried in the MsgB of the 2-step RACH procedure. If the SCG of the terminal is recovered through the SR process initiated on the SR resource, the response message may be carried in an SR request response message of the SR process.

In practical application, the response message sent by the first network node may indicate that the terminal is allowed to recover the SCG, or may deny the terminal from recovering the SCG, which may be determined according to practical situations, and this is not limited in this embodiment of the present application.

In this optional embodiment, the response message carries SCG configuration information, which indicates that the response message sent by the first network node may indicate that the terminal is allowed to recover SCG. It should be understood that, if the first network node refuses the terminal to recover SCG, the response message may not include SCG configuration information.

The SCG configuration information at least comprises primary and secondary cell PSCell configuration. Further, the SCG configuration information may also include at least one SCell configuration.

In a specific implementation, the PSCell configuration included in the SCG configuration information may be the same as or different from the PSCell configuration of the SCG suspended by the terminal. The SCell configuration included in the SCG configuration information may be the same as or different from the SCell configuration of the SCG suspended by the terminal.

The following is exemplified by the PSCell configuration included in the SCG configuration information:

in a case that the PSCell configuration included in the SCG configuration information is different from the PSCell configuration of the SCG suspended by the terminal, further, the PSCell configuration included in the SCG configuration information may be a complete PSCell configuration, in which case, the terminal may directly perform recovery of the SCG according to the PSCell configuration included in the SCG configuration information; the PSCell configuration included in the SCG configuration information may also be a change value of a PSCell configuration, and in this case, the terminal needs to perform recovery of the SCG according to the PSCell configuration included in the SCG configuration information and the PSCell configuration of the SCG suspended by the terminal.

It should be understood that the implementation principle of the above example is also applicable to the SCell configuration in the SCG configuration information, and is not described herein again to avoid repetition.

In this embodiment, the terminal may send an SCG recovery complete message to at least one of the first network node and the MN corresponding to the terminal. For ease of understanding, the detailed description is as follows:

optionally, after the target resource is used to send the SCG recovery request message to the first network node, the method further includes:

an SCG recovery complete message is sent to the first network node.

In this optional embodiment, the terminal may send an SCG recovery completion message to the first network node when the SCG recovery is successful, indicating that the terminal SCG recovery is successful.

sending an SCG recovery completion message to the MN corresponding to the terminal at a first time, where the first time is any one of the following:

the time when the terminal completes the recovery of the SCG;

and the terminal sends the SCG recovery request message.

Further, if the SCG of the terminal is recovered through the 4-step RACH procedure initiated on the RACH resource, the first time may also be: the moment when the terminal sends Msg 1.

Further, the sending, at the first time, the SCG recovery complete message to the MN corresponding to the terminal includes any one of:

1) sending an SCG recovery completion message to a main node MN corresponding to the terminal through the first network node at a first moment;

2) and directly sending an SCG recovery completion message to the MN corresponding to the terminal at the first time.

In the scenario of 1), after receiving an SCG recovery completion message sent by a terminal, a first network node may forward the received SCG recovery completion message to an MN corresponding to the terminal through an interface such as Xn, and the terminal may not need to communicate with the corresponding MN. In the scenario of 2), the terminal may directly send the SCG recovery complete message to the MN corresponding to the terminal, and the first network node may not need to communicate with the MN corresponding to the terminal.

It should be noted that, in this embodiment of the present application, the second network node and the first network node may be the same network node, or may be different network nodes, which may be determined specifically according to an actual situation, and this is not limited in this embodiment of the present application.

The second network node may be an MN corresponding to the terminal or an SN corresponding to the terminal before the SCG is suspended for the terminal. The first network node may be a SN corresponding to the terminal before the SCG is suspended by the terminal, or a network node of a cell group in a cell list indicated by the second network node.

Optionally, the first network node may be a network node of any one of the following:

any cell group in the first cell list;

a first cell group in a first cell list, wherein a primary cell PSCell and a secondary cell PSCell in the first cell group meet a cell quality threshold;

a second cell group in the first cell list, wherein the PSCells included in the second cell group are the PSCells with the best cell quality in the candidate PSCells included in the first cell list;

the terminal suspends a third cell group corresponding to an auxiliary node SN before SCG;

wherein each of the cell groups includes at least a PSCell.

The first cell list may include at least one PSCell identity, each PSCell identity corresponding to at least one Scell identity. Each cell group may include one PSCell and its corresponding one or more Scell identifications.

In the case that there are at least two pscells in the first cell list that meet a cell quality threshold, the first cell group may be any cell group that includes any of the at least two pscells.

For ease of understanding, examples are illustrated below:

assume that the first cell list includes PSCell identity a (identifying PSCell1), PSCell identity b (identifying PSCell2), PSCell identity c (identifying PSCell 3). Wherein PSCell1 and PSCell2 satisfy a cell quality threshold; the cell quality of PSCell2 is better than the cell quality of PSCell1 and PSCell 3; the PSCell3 is a PSCell corresponding to an SN before the SCG is suspended by the terminal. Then:

in case the first network node is a network node of any cell group in the first cell list, the first network node may be a network node of any cell group comprising PSCell1, PSCell2 or PSCell 3.

In the case where the first network node is a network node of the first cell group, the first network node may be a network node of any cell group including PSCell1 or a PSCell.

In the case where the first network node is a network node of the second cell group, the first network node may be a network node of any cell group including PSCell 2.

In the case where the first network node is a network node of the third cell group, the first network node may be a network node of any cell group including PSCell 3.

It should be noted that the first cell list and the cell quality threshold may be configured by the second network node, but are not limited thereto. The cell quality threshold may be measured by, but not limited to, any of the following parameters: reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal-to-Noise and Interference plus Noise Ratio (SINR).

In this embodiment of the present application, optionally, before the SCG of the terminal is resumed using the target resource when the secondary cell group SCG of the terminal is in the suspended state, the method further includes:

and receiving SCG suspension configuration information sent by the second network node.

Further, the SCG suspend configuration information includes at least one of:

first identification information for indicating recovery of the SCG of the terminal;

second identification information used for indicating to recover the SCG of the terminal, wherein the second identification information is obtained by truncating the first identification information;

the RACH resource;

the SR resource;

a first cell list for indicating to restore the SCG of the terminal;

a cell quality threshold for indicating recovery of the SCG of the terminal.

The RACH resource may be understood as a RACH resource for recovering the SCG of the terminal; the SR resource may be understood as an SR resource for recovering the SCG of the terminal. It should be noted that, reference may be made to the foregoing description for the first identification information, the second identification information, the RACH resource, the SR resource, the first cell list, and the cell quality threshold, which is not described herein again.

Further, the first identification information includes at least one of:

a Cell Radio Network Temporary Identifier (C-RNTI) used by the terminal in a master Cell group MCG;

C-RNTI used by the terminal in SCG;

a resume ID of SCG context information of the terminal.

The second identification information may be a truncated recovery identification (truncated resume ID) of the SCG context information of the terminal; similarly, the aforementioned third identification information may also be regarded as a truncated recovery identification of the SCG context information of the terminal.

In an embodiment of the present application, the SCG suspend configuration information may be used for at least one of:

indicating to put the SCG of the terminal in a suspended state;

and instructing the terminal to recover the related information of the SCG.

In a case where the SCG suspend configuration information is used to indicate that the SCG of the terminal is placed in the suspend state, the terminal may place the SCG in the suspend state in a case where the SCG suspend configuration information is received. Therefore, the SCG can be hung up quickly, and the power consumption of the terminal can be saved.

When the SCG suspend configuration information is only used to instruct the terminal to resume the relevant information of the SCG, the condition for triggering the SCG of the terminal to be in the suspend state is that the terminal receives the SCG suspend configuration information, but the terminal can resume the SCG of the terminal according to the configuration content of the SCG suspend configuration information. Therefore, the SCG can be quickly recovered, and the requirement of large-data-volume transmission of the terminal can be met.

In the case that the SCG suspend configuration information is used to indicate that the SCG of the terminal is placed in the suspend state and also to indicate that the terminal recovers the relevant information of the SCG, the terminal may place the SCG in the suspend state after receiving the SCG suspend configuration information, that is, the terminal receives the SCG suspend configuration information as the trigger condition for triggering the SCG of the terminal to be in the suspend state. Further, the SCG suspend configuration information may be saved, and then the SCG of the terminal may be resumed according to the configuration content of the SCG suspend configuration information. Therefore, the SCG of the terminal can be quickly hung up, and the power consumption of the terminal can be saved; and the quick recovery of the SCG can be realized, so that the requirement of large data volume transmission of the terminal can be met.

It should be noted that, in this embodiment of the present application, an SCG processing method may also be protected, where the SCG processing method is applied to a terminal, and the method may include:

and under the condition of receiving the SCG suspension configuration information, placing the SCG of the terminal in a suspension state.

Optionally, after placing the SCG of the terminal in the suspend state, the method may further include:

recovering the SCG of the terminal by using the target resource;

The SCG processing method is mainly different from the SCG processing method of the embodiment of the method of fig. 2 in that: the SCG processing method mainly focuses on how the terminal suspends the SCG; the processing method of the embodiment of the method of fig. 2 mainly focuses on how the terminal recovers the SCG.

Referring to fig. 3, fig. 3 is a second flowchart of the SCG processing method provided in the embodiment of the present application. The SCG processing method of the embodiment of the application is applied to a first network node.

As shown in fig. 3, the SCG processing method applied to the first network node may include the steps of:

step 301, when the secondary cell group SCG of the terminal is in a suspended state, the SCG of the terminal is recovered by using the target resource.

In the SCG processing method of this embodiment, when the secondary cell group SCG of the terminal is in the suspended state, the SCG of the terminal is recovered using the target resource. Therefore, the embodiment of the application solves the problem of recovery of the SCG after the SCG is suspended, so that the requirement of large data volume transmission of the terminal can be met.

Optionally, in a case that the target resource is the RACH resource, the SCG of the terminal is recovered through an RACH procedure initiated on the RACH resource;

Optionally, the recovering the SCG of the terminal by using the target resource includes:

receiving an SCG recovery request message sent by the terminal by using a target resource, wherein the SCG recovery request message comprises at least one of the following items: first identification information, second identification information or third identification information for indicating recovery of the SCG of the terminal; the terminal recovers the SCG reason value of the terminal;

Optionally, after the target resource is used to receive the SCG recovery request message sent by the terminal, the method further includes:

sending a response message of the SCG recovery request message to the terminal by using the target resource;

and receiving an SCG recovery completion message sent by the terminal.

Optionally, after receiving the SCG recovery complete message sent by the terminal, the method further includes:

and sending the SCG recovery completion message to a main node MN corresponding to the terminal.

Optionally, the first network node is a network node of any one of the following:

any cell group in the first cell list;

wherein each of the cell groups includes at least a PSCell.

It should be noted that, this embodiment is taken as an implementation of the first network node corresponding to the embodiment of the method in fig. 2, so that reference may be made to the relevant description in the above embodiment of the method, and the same beneficial effects may be achieved.
