Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable.

For convenience of understanding, some contents related to the embodiments of the present invention are explained below:

currently, in a mobile communication system, two wireless access nodes/base stations may be deployed for a terminal, and service transmission is provided for the terminal at the same time, that is, a dual connectivity mode. The dual connectivity scheme has two network nodes, one of which is called a Master Node (MN) and the other is called a Secondary Node (SN). At each network node, carrier Aggregation (CA) may also be used, i.e. a series of serving cells, also called cell groups, controlled by the node is configured for the UE. The Cell Group controlled by the Master node MN is called Master Cell Group (MCG), and the Cell Group controlled by the slave node SN is called Slave Cell Group (SCG). Each Cell group includes a Special Cell (SpCell) and a series of Secondary cells (scells). 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).

At present, there is a fuzzy period of the SCG state in the SCG state control process, that is, when the network side determines that the UE has no uplink data to send and the network side also has no downlink data to send, the MN or the SN initiates SCG deactivation, and the MN sends a deactivation command to the UE. If the UE may have uplink data again on the SCG before receiving the SCG deactivation command, the UE may send a BSR on the SCG or initiate random access. At this time, the SN will set the UE in an active state to activate the SCG for the UE, and the SN considers that the SCG enters the active state on the SN side. At this time, the UE receives the SCG deactivation command from the MN, and the SCG enters a deactivation state at the UE side. The SN informs the MN of the SCG activated state, and the MN considers that the UE is in the SCG activated state. Thereby causing the UE and the network side to understand the SCG status inversely, and thus there is a problem of SCG status ambiguity.

The method for controlling the secondary cell group state provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings by using some embodiments and application scenarios thereof.

Referring to fig. 2, fig. 2 is a flowchart of a secondary cell group status control method provided in an embodiment of the present application, and as shown in fig. 2, the secondary cell group status control method includes the following steps:

step 201, the first network element sends target information and/or receives the target information, wherein the target information is used for controlling the SCG state of the auxiliary cell group of the terminal.

The first network element may be a MN, and/or a SN.

In the embodiment of the application, a first network element sends target information and/or receives the target information, wherein the target information is used for controlling the SCG state of a secondary cell group of a terminal. In this way, by controlling the SCG state by the target information, it is possible to reduce resources consumed by the network side and to reduce power consumption of the terminal.

Optionally, the receiving the target information includes:

receiving first indication information sent by a second network element, wherein the first indication information is used for indicating at least one of the following items:

the first network element directly activates first authorization information of SCG;

and the first network element directly deactivates the second authorization information of the SCG.

Wherein the target information may include first indication information.

The first network element may be an MN, and the second network element may be an SN; alternatively, the first network element may be a SN, and the second network element may be a MN.

In one embodiment, in a case that the first indication information is used as first authorization information indicating that the first network element directly activates SCG, the first network element may be instructed to determine whether to allow direct activation of SCG according to a trigger condition for activating SCG, for example:

if the terminal triggers and activates the SCG, allowing the first network element to directly activate the SCG;

and if the first network element triggers the activation of the SCG, the first network element is not allowed to directly activate the SCG.

Illustratively, the MN (second network element) indicates to the SN (first network element), if the terminal triggers an SCG activation procedure, and if the SCG activation reason is to recover MCG (MCG recovery), the first network element is allowed to directly activate SCG.

Illustratively, if the first network element is MN, the second network element is SN, downlink (DL) data arrives at MN, and MN prepares to use SCG to transmit the DL data, then MN may be considered to trigger activation of SCG; the terminal sends an SCG activation request, and the terminal may be considered to trigger activation of SCG. The terminal initiates a random access or scheduling request on the SCG/PSCell, which may also be considered as the terminal sending an SCG activation request.

In one embodiment, in a case that the first indication information is used as second authorization information indicating that the first network element directly deactivates an SCG, the first network element may be instructed to determine whether to allow direct deactivation of the SCG according to a trigger condition for deactivating the SCG, for example:

if the terminal triggers to deactivate the SCG, allowing the first network element to directly deactivate the SCG;

and if the first network element triggers and deactivates the SCG, not allowing the first network element to directly deactivate the SCG.

Exemplarily, the first network element is an MN, the second network element is an SN, the terminal requests the MN to deactivate the SCG due to overheating or low power, and at this time, if the MN obtains the second authorization, the SCG may be deactivated first and then the SN is notified; if SCG deactivation is triggered by the MN, the MN is not allowed to directly deactivate SCGs.

For example, the terminal sends an SCG deactivation request, and then may consider that the terminal triggers the deactivation of SCG. For example, the terminal sends UE assistance information, wherein SCG deactivation indication/request information is indicated.

It should be noted that, at present, when downlink data arrives at the MN and the MN wants to activate the SCG to use the resources of the SCG, the MN needs to send an SCG activation request to the SN, and after receiving an acceptance response of the SN to the activation request, sends an SCG activation command to the UE, so that the SCG status control is less effective. In this embodiment, the SN may send an authorization to activate SCG to the MN in advance in some cases, that is, allow the MN to send SCG activation to the UE without SN confirmation. Accordingly, when the condition is not allowed, the SN may also cancel the authorization, thereby being able to improve the effectiveness of SCG state control.

In this embodiment, first indication information sent by a second network element is received, where the first indication information is used to indicate at least one of the following: the first network element directly activates first authorization information of SCG; and the first network element directly deactivates the second authorization information of the SCG. Therefore, the first network element can directly activate or deactivate the SCG based on the first indication information, can realize quick activation or deactivation of the SCG, can improve the effectiveness of SCG state control, and can solve the problem of low effectiveness of the SCG state control at present; and frequent signaling interaction of the Xn interface can be avoided.

Optionally, the method further includes:

the first network element sends a response to the first indication information to the second network element; and/or the presence of a gas in the gas,

and the first network element sends a first request to the second network element, wherein the first request is used for requesting the second network element to send the first indication information.

In one embodiment, before a first network element receives first indication information sent by a second network element, the first network element sends a request to the second network element to request the second network element to send the target information; after the first network element receives the first indication information sent by the second network element, the first network element sends a response to the first indication information to the second network element.

For example, the MN applies for or gives a first authorization to the SN, which configures or otherwise gives the MN an acknowledgement of the first authorization to the SN.

Optionally, the first authorization information is used to indicate at least one of the following:

a first grant indicating that the first network element is allowed to directly activate the SCG;

activating the first authorization;

deactivating or canceling the first authorization;

not authorizing or allowing the first network element to directly activate SCG;

a validity time of the first grant;

the first authorized associated SCG configuration.

Wherein within the validity time, the first authorization may be considered valid; if the valid time is out, the first authorization may be considered to be cancelled.

In one embodiment, when the second network element authorizes the first network element to directly activate SCG, the second network element sends SCG information to the first network element, where the SCG information includes an associated SCG configuration of the first authorization, and the SCG information allows the first network element to send to a terminal.

It can be understood that the SCG configuration information associated with the first grant is SCG configuration information sent to the terminal if the SCG is directly activated by the first network element during the validity of the first grant. If the first grant is not valid (for example, the validity period of the first grant has passed), the first network element may delete the stored associated SCG configuration.

Optionally, the second authorization information is used to indicate at least one of the following:

a second grant indicating that the first network element is allowed to directly deactivate the SCG;

activating the second authorization;

deactivating or cancelling the second authorization;

not authorizing or allowing the first network element to directly deactivate the SCG;

a validity time of the second grant;

the second authorized associated SCG configuration.

In one embodiment, when the second network element authorizes the first network element to directly deactivate the SCG, the second network element sends, to the first network element, SCG information that allows the first network element to send to the terminal, where the SCG information includes the associated SCG configuration of the second authorization.

It can be understood that the SCG configuration information associated with the second grant is SCG configuration information sent to the terminal if the SCG is directly deactivated by the first network element during the validity of the second grant. In case the second grant is not valid (e.g. the validity period of the second grant has passed), the first network element may delete the stored associated SCG configuration.

Optionally, the first authorized associated SCG configuration includes at least one of:

after the SCG is activated, the target state of at least one service cell in the SCG;

the number or list of serving cells that are activated immediately in the SCG after the SCG is activated;

after the SCG is activated, the SCG can use the uplink resource;

and after the SCG is activated, the SCG can use the downlink resources.

For example, after the SCG is activated, the UE can have available uplink resources such as random access resources, PUCCH resources, configuration grant (configured grant), and the like. Or have reference signal resources available to make measurements.

Optionally, the second authorized associated SCG is configured to indicate at least one of:

after the SCG is deactivated, the terminal clears at least part of downlink resources of the SCG;

after the SCG is deactivated, the terminal clears at least part of uplink resources of the SCG;

after the SCG is deactivated, the terminal does not execute a first operation on the SCG, wherein the first operation comprises at least one of the following operations:

beam Management, beam Failure Detection (BFD), beam Failure Recovery (BFR), channel State Information (CSI) measurement, CSI measurement reporting, random access, radio Link Monitoring (RLM) measurement, and Radio Resource Management (RRM) measurement.

For example, after the SCG is deactivated, the random access resource of the SCG is deleted by associating the SCG configuration information, thereby saving the network uplink resource. It is to be understood that in some cases, the associated SCG configuration of the second grant may also be generated by the first network element.

Optionally, the method further includes:

and under the condition that the SCG of the terminal is directly activated or directly deactivated by the first network element, the first network element indicates the state of the SCG to the second network element.

In this embodiment, the first network element is an MN, the second network element is an SN, and the method for controlling the secondary cell group state includes the following steps:

the SN sends first indication information to the MN;

the MN sends a response to the first indication information to the SN.

The first indication information may be sent at any time, for example, the SN addition (addition), the SN change (change), the SN reconfiguration, the SCG being in the deactivated state, and the SCG being in the activated state.

In one embodiment, before receiving the first indication information sent by the SN, the MN sends a request to the SN to request the SN to send the target information; after the MN receives the first indication information sent by the SN, the MN sends a response to the first indication information to the SN.

At present, when downlink data reaches MN and MN wants to activate SCG to use SCG resource, MN sends SCG activation request to SN, and sends SCG activation command to UE after receiving SN acceptance response to SCG activation request. In this embodiment, to implement SCG fast activation, the SN may in some cases send an authorization to activate SCG to the MN in advance, i.e. allow the MN to directly activate SCG of the UE without SN confirmation or participation. Accordingly, the SN may also revoke authorization when conditions do not allow. Therefore, the activation and deactivation of the SCG can be accelerated, and the effectiveness of controlling the SCG state can be improved.

Optionally, the receiving the target information includes receiving target information sent by a second network element, where the target information includes at least one of the following:

SCG status indication information;

indicating information for indicating the first network element to cancel sending of an SCG deactivation command to the terminal;

and indicating the first network element to send the indication information of the SCG activation command to the terminal.

In this embodiment, the first network element is an MN, the second network element is an SN, and the method for controlling a secondary cell group state includes the following steps:

(1): the SN initiates an SCG deactivation request;

(2): MN sends SCG deactivation request acceptance response to SN;

(3): before the UE receives an SCG deactivation command sent by the MN, if uplink data arrives, the UE initiates RACH or SR to the SCG under the condition of no PUSCH resource;

(4): after receiving the RACH or SR of the UE, the SN judges the state of the SCG based on the information in the RACH or SR;

(5): if the SN judges that the SCG is still in the activated state, the SN sends indication information for indicating the state of the SCG (indicating that the SCG of the UE is currently in the activated state) and/or requesting to cancel a command for transmitting the SCG deactivation to the MN;

(6): after receiving the indication information sent by the SN, the MN cancels the transmission of the SCG deactivation command or sends the SCG activation command to the UE.

Therefore, after receiving the SCG activation notification, if the SCG deactivation command is not sent, the MN can cancel the sending, and if the SCG deactivation command is sent, the MN can send the SCG activation command to the UE again, so that the problem of the fuzzy state of the SCG can be solved.

In this embodiment, by receiving the target information sent by the second network element, it is possible to avoid inconsistency of understanding of the SCG states by the network side and the terminal, and further, it is possible to avoid subsequent misconfiguration caused by inconsistency of understanding of the SCG states by the network side and the terminal, and avoid communication abnormality, thereby improving stability of control of activation and deactivation of the SCG.

Optionally, the target information includes at least one of the following:

SCG deactivation request;

an SCG deactivation indication;

an SCG activation request;

an SCG activation indication;

SCG status indication information.

The SCG deactivation indication includes a response to the SCG deactivation request initiated by the second network element, or the first network element indicates the second network element to deactivate the SCG. The SCG activation indication includes a response to the SCG activation request initiated by the second network element, or the first network element indicates that the second network element activates SCG. The SCG status indication information indicates the current status of the SCG.

Optionally, after the first network element sends the target information and/or receives the target information, the method further includes:

the first network element starts a timer.

Optionally, after the first network element starts the timer, the method further includes:

the first network element does not perform at least one of the following during the timer run:

transferring part or all of the target information;

activating the SCG;

deactivating the SCG;

responding to the SCG activation request of the terminal;

and responding to the SCG deactivation request of the terminal.

In one embodiment, not activating the SCG may include at least one of:

SCG is not scheduled;

not responding to a random access or SR of the UE;

the SCG activation request of the UE is not responded to.

In this embodiment, by limiting the behavior that the first network element does not execute during the running of the timer, the problem of SCG state ambiguity can be solved, and thus the stability of SCG activation and deactivation control can be improved.

Optionally, in a case that the timer is expired or not running, the behavior of the first network element includes at least one of:

allowing the target information to be communicated;

allowing the SCG to be deactivated;

allowing the SCG to be activated;

allowing to respond to the SCG activation request of the terminal;

and allowing the SCG deactivation request responding to the terminal.

In this embodiment, the timer may be used to keep the SCG state synchronization between the first network element and the second network element, and after the first network element sends and/or receives the target information, the first network element starts the timer, so that the network side can keep the SCG state synchronization.

Optionally, the method further includes: the first network element stops the timer if at least one of the following conditions is met:

receiving a response to the target information sent by a second network element;

an SCG release request or indication is received.

In some specific scenarios, the condition for the first network element to stop the timer further includes at least one of:

receiving a status indication of the SCG;

receiving an SCG activation indication;

receiving an SCG deactivation indication;

receiving an SCG activation request;

receiving an SCG deactivation request;

in one embodiment, when the target information includes an SCG activation request, an SCG activation indication, or SCG status indication information, if the first network element receives an SCG release request or indication, the first network element stops the timer.

For example, after the first network element sends the SCG deactivation request to the second network element, the first network element starts the timer, and during the running of the timer, the first network element does not send the SCG deactivation request any more. During the running period of the timer, if the first network element receives the indication that the second network element successfully deactivates the SCG, the first network element stops the timer, or the first network element does not stop the timer at this time, and during the running period of the timer, the first network element does not send an SCG activation request.

For another example, after the SCG deactivation instruction sent by the first network element to the second network element (the SCG deactivation instruction may also be a response to the SCG deactivation request sent by the second network element), the timer is started. During the timer running, the first network element does not schedule the UE. And if the first network element receives the indication that the SCG indicated by the second network element is successfully deactivated during the running period of the timer, the first network element stops the timer. And if the timer is overtime, the first network element resumes scheduling the UE or responds to the information sent by the UE on the SCG.

In one embodiment, the first network element is a SN, the second network element is a MN, and the SN starts a timer after sending one of the following information to the MN:

SCG deactivation request;

an SCG deactivation indication;

an SCG activation request;

an SCG activation indication;

SCG status indication information;

the SCG deactivation indication may include a response to the SCG deactivation request initiated by the MN, or the SN may indicate the MN to deactivate the SCG. The SCG activation indication includes a response to the MN-initiated SCG activation request, or the SN indicates that the MN activates SCG.

Additionally, during the timer running, the behavior of the SN includes at least one of:

not sending an SCG deactivation request to the MN;

not sending SCG activation request to MN;

SCG is not activated;

the state indication information of the SCG is not transmitted to the MN.

Wherein the SN does not send an SCG deactivation request to the MN during the timer operation, thereby being capable of prohibiting the SN from frequently requesting for a short time; during the running of the timer, the SN does not send an SCG activation request to the MN, so that the SN can be prohibited from frequently changing the SCG state in a short time; during the running of the timer, the SN does not activate the SCG, so that the potential problem of inconsistent state caused by the SN activating the SCG by itself can be avoided.

For example, the SN starts the timer after it sends an SCG deactivation request to the MN, and during the timer running, the SN does not schedule SCGs. If the SN receives the indication that the SCG sent by the MN is successfully deactivated during the running period of the timer, the SN stops the timer. If the SN receives the rejection response of the MN to the request for deactivating the SCG during the running period of the timer, the SN stops the timer, and the SN can resume the scheduling of the SCG.

In one embodiment, the first network element is a MN, the second network element is a SN, and the MN starts the timer after performing one of the following:

sending an SCG deactivation request to the SN;

sending an SCG deactivation indication to the SN;

sending an SCG activation request to the SN;

sending an SCG activation indication to the SN;

and receiving SCG state indication information sent by the SN.

In addition, during the timer run, the behavior of the MN includes at least one of:

not sending an SCG activation request to the SN;

not sending SCG deactivation request to SN;

SCG is not activated;

not responding to the SCG activation request of the UE;

the state indication information of the SCG is not transmitted to the MN.

Optionally, the sending target information includes:

if the first network element receives a random access message or a scheduling request sent by a terminal and the random access message or the scheduling request does not contain second indication information, the first network element sends third indication information to the terminal;

the second indication information is used to indicate that the SCG is requested to be activated or indicate that the current state of the SCG is a deactivated state, and the third indication information is used to indicate the terminal to ignore a SCG deactivation command received from the second network element.

In addition, the third indication information may be used to indicate that the terminal ignores an SCG deactivation command received from the second network element within a third preset time period, where the third preset time period may be 500ms, or 1s, or 5s, and the like, which is not limited in this embodiment.

In this embodiment, the first network element is an SN, the second network element is an MN, and the method for controlling the secondary cell group state includes the following steps:

(1): when the SCG of the UE is in a deactivated state, if uplink data reaches the SCG, the UE indicates the SCG to Request to activate the SCG or indicates the current state of the SCG to be in a deactivated state in the process of initiating RACH or SR to the SCG or after the UE initiates Random Access (RACH) or Scheduling Request (SR) to the SCG;

The following is an illustration of 2 specific examples. The first network element is an SN, and the second network element is an MN.

Example 1:

the method for controlling the state of the auxiliary cell group comprises the following processes:

(1): SCG of UE is in deactivation state;

(2): UE sends uplink data, requests the SN to activate the SCG, for example, initiates RACH or scheduling request;

(3): the SCG of the UE is activated;

(4): the SN receives an SCG activation request sent by the MN, for example, the SCG activation request may be sent by the MN to the SN after downlink data arrives at the MN. The SN receives the SCG activation request sent by the MN under the condition that the SN does not inform the MN that the SCG is activated;

(5): the SN sends SCG state indication information to the MN, wherein the SCG state indication information is used for indicating the current state of the SCG. Further, the SCG status indication information does not trigger the MN to send an SCG activation command to the UE.

Example 2:

(1): SCG is in deactivation state;

(2): the SN receives an SCG activation request sent by the MN;

(3): the SN sends a reply to the MN for the SCG activation request. For example, it is confirmed that SCG can be activated;

(4): before the UE receives an SCG activation command sent by the MN, the UE sends uplink data on the SCG and requests the SN to activate the SCG, for example, initiates an RACH or scheduling request;

(5): the SN receives the SCG activation request of the UE, judges that the UE does not receive the SCG activation command sent by the MN before sending the message, and sends any one of the following indication information to the UE:

SCG status indication information;

SCG configuration;

indicating whether the UE ignores all or part of SCG status information, and/or all or part of SCG configuration information, received from the MN over a period of time. For example, the SN instructs the UE to activate SCG and to reconfigure a part of SCG configuration, and instructs the UE not to initiate random access if it receives the synchronization reconfiguration parameter of SCG from the MN.

In this embodiment, the first network element sends the current state of the SCG to the second network element, or the first network element sends the target information, so that the problem of processing that the terminal and the second network element request the first network element to activate the SCG at the same time can be solved.

Referring to fig. 3, fig. 3 is a second flowchart of a secondary cell group status control method according to an embodiment of the present application, and as shown in fig. 3, the secondary cell group status control method includes the following steps:

step 301, the terminal receives target information for controlling the SCG state of the secondary cell group.

In the embodiment of the application, the terminal receives target information for controlling the SCG state of the auxiliary cell group. In this way, the SCG state is controlled by the target information, so that resources consumed by the network side can be reduced, and power consumption of the terminal can be reduced.

Optionally, the receiving, by the terminal, target information for controlling the SCG state includes:

the terminal receives an SCG deactivation command sent by a first network element at a first moment;

the method further comprises the following steps:

and if the terminal receives the SCG activation command within a second preset time before and/or after the first time, the terminal ignores the SCG deactivation command.

The second preset time period may be 500ms, or 1s, or 5s, and the like, which is not limited in this embodiment.

As illustrated in the following by a specific embodiment, the method for controlling the secondary cell group status includes the following steps:

(1): the SN initiates an SCG deactivation request;

(2): MN sends SCG deactivation request acceptance response to SN and sends SCG deactivation command to UE;

(3): when the UE does not receive the SCG deactivation command, the SCG of the UE is still in an activated state, if uplink data reaches the SCG, the UE initiates RACH or SR to the SCG under the condition of no PUSCH resource;

(4): the UE receives an SCG activation command from the SN;

(5): if the UE receives the SCG deactivation command from the MN within the preset time range of receiving the SCG activation command, the UE ignores the SCG deactivation command. The preset time range may be determined by protocol convention or network configuration.

In the embodiment, the SCG deactivation command is received from the second network element within a short time after the SCG activation command is received from the first network element, and the terminal ignores the received SCG deactivation command, so that the problem of fuzzy SCG state can be solved, and the stability of SCG activation and deactivation control can be improved.

and the terminal receives third indication information sent by the first network element, wherein the third indication information is used for indicating the terminal to ignore the SCG deactivation command received from the second network element.

a terminal receives a first SCG state control instruction sent by a first network element;

the terminal receives a second SCG state control instruction sent by a second network element;

the method further comprises the following steps:

and the terminal executes the first SCG state control instruction or the second SCG state control instruction according to a preset priority.

Wherein the first SCG state control instruction may be used to control SCG state, and may include at least one of: SCG deactivation request, SCG deactivation indication, SCG activation request or SCG activation indication, etc. The second SCG state control instruction may be for controlling SCG state, and may include at least one of: SCG deactivation request, SCG deactivation indication, SCG activation request or SCG activation indication, etc.

The preset priority may be used to indicate the highest priority among the first network element and the second network element. Illustratively, the preset priority may comprise a priority of the first network element and a priority of the second network element.

(1): the SCG of the UE is in a deactivation state;

(2): UE initiates an SCG activation request to the SN and receives an acceptance response of the SN;

(3): the UE receives an acceptance response of the SCG activation request from the SN; meanwhile, the UE receives an SCG deactivation command from the MN;

(4): and the UE uses the SCG deactivation command sent by the MN as a high priority and ignores the SCG activation command sent by the SN.

In the embodiment, the terminal determines how to control the state of the SCG based on the defined priority, and can solve the problem of the fuzzy state of the SCG caused when the terminal simultaneously receives the SCG state control instruction sent by the SN and the MN.
