In some embodiments, the embodiments of the present application may be applied to a multi-card terminal, which refers to a terminal in which more than one USIM card is installed. Taking a dual-card terminal as an example, the dual-card terminal may be classified into a single-transmission single-reception terminal, a single-transmission dual-reception terminal, and a dual-transmission dual-reception terminal according to whether the terminal supports simultaneous transmission or reception in a network of two cards.

Single-shot single-receiving terminal: the terminal can only alternate the transmission and reception of information in the network of two cards in a time-division manner.

Single-shot double-receiving terminal: the terminal can only transmit uplink through the network of two cards alternately in a time division mode, but supports downlink reception through the network of two cards at the same time.

Double-transmitting double-receiving terminal: the terminal supports uplink transmission and downlink reception in the network of two cards simultaneously.

In some embodiments, for a dual-transmit dual-receive multi-card terminal, each card may use separate hardware/capabilities to support parallel transmissions. In addition, in the case that part of hardware/capability of the terminal (for example, a mobile phone) can be dynamically switched between two cards, the terminal can indicate to the network side that its own part of capability is limited or the capability is no longer limited, and can also request to deactivate some functions or request to release some resources. For example, when card a is in a connected state and card B is in a disconnected state, the capabilities of the terminal are occupied by card a. If the card B is about to establish or restore the RRC connection, the capability of the card a needs to be partially cut into the card B, and at this time, the terminal needs to indicate a short partial capability limited state to the network a, otherwise, the network a may schedule the terminal with the UE capability reported by the terminal before, which results in that the terminal may lose the data of the network a or cause the resource waste of the network a.

In some embodiments, it may be applied to a dual connectivity (Dual Connectivity, DC) scenario in which a terminal is provided with resources of two network nodes, one of which is referred to as a Master Node (MN) and the other is referred to as a Secondary Node (SN). At each network node, carrier aggregation techniques (Carrier Aggregation, CA) may also be used, i.e. a series of serving cells controlled by the node are configured for the terminal, which constitute a cell group (cell group). MN-controlled cell group is primary cell group (Master Cell Group, MCG) and SN-controlled secondary cell group (Secondary Cell Group, SCG). Each Cell group contains a Special Cell (SpCell) and a series of Secondary cells (scells). The special Cell is called a Primary Cell (PCell) in the MCG, and the special Cell is called a Primary secondary Cell (Primary Secondary Cell, PSCell) in the SCG.

The following describes in detail, by means of some embodiments and application scenarios thereof, a secondary cell group information sending method, a receiving method, a terminal, a device and a medium provided by the embodiments of the present application with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a secondary cell group information sending method according to an embodiment of the present application, as shown in fig. 2, including the following steps:

Step 201, a terminal sends a first message according to a first mode, wherein the first message is used for indicating or updating SCG deactivation preference information of the terminal;

wherein the first mode includes at least one of:

ignoring a prohibit timer (prohibit timer) when sending the first message;

when the first message is sent, the prohibit timer is not started;

after the first message is sent, executing a first operation;

preference information indicating the terminal to perform at least one of RLM, BFD, and RRM measurements when the first message is transmitted;

the first operation includes at least one of:

controlling the running state of the TAT related to the SCG;

In the application scenario of the multi-card terminal, the terminal corresponds to one card of the multi-card terminal, that is, the SCG deactivation preference information is SCG deactivation preference information of the card corresponding to the terminal. For example: the multi-card terminal includes a card a and a card B, and step 201 may be to transmit SCG deactivation preference information of the card a or the card B. It should be noted that, in the embodiment of the present application, the application is not limited to multi-card terminals, for example: the above step 201 may also be performed for a single card terminal.

The prohibit timer may be an SCG deactivation preference prohibit timer (SCG deactivation preference prohibit timer) or an SCG status preference prohibit timer (SCG state preference prohibit timer).

The SCG deactivation preference information may be preference information determined according to the current capability, service, resource, etc. of the terminal.

When the first message is sent, the prohibit timer may be ignored, and if the prohibit timer is running when the terminal sends the first message, the terminal may still send the first message.

The step of not starting the prohibit timer when the first message is transmitted may be a step of not starting the prohibit timer when the terminal transmits the first message.

The first message may be sent when the prohibit timer is not in an operation state, and the first message may be sent when the prohibit timer is not in an operation state and the first message is not sent when the prohibit timer is in an operation state, where the set time period of the prohibit timer does not exceed the first preset value. The disabling the timer not being in operation includes: not started, has timed out.

The first operation may be performed after the first message is sent, where the first operation is performed when the first message is sent.

The TAT related to the SCG may be an uplink synchronization timer of the SCG, and the running state of the TAT related to the SCG may be stopping or continuing to run the TAT.

The above-mentioned controlling the random access operation of the at least one serving cell of the SCG in case of receiving the SCG activation command may be initiating the random access in the at least one serving cell of the SCG in case of receiving the SCG activation command.

When the first message is sent, the preference information instructing the terminal to perform at least one of RLM, BFD and RRM measurement may be that the preference information of at least one of RLM, BFD and RRM measurement is carried in the first message, or the preference information of at least one of RLM, BFD and RRM measurement is sent together with the first message through other messages.

In the embodiment of the application, through the steps, the terminal can report the SCG deactivation preference information in time so as to avoid influencing the communication performance of the terminal and achieve the effect of improving the communication performance of the terminal.

In addition, after the first message is sent, a first operation is performed to control the running state of the TAT related to the SCG, and/or control the random access operation of at least one serving cell of the SCG, so that it can be clear by the network side whether the SCG is successfully activated or can start to be scheduled, so that in the case that it is determined that the SCG is successfully activated or can start to be scheduled, the network side communicates with the terminal, and further, the communication performance of the terminal is improved, for example: in case of performing a random access operation of at least one serving cell of the SCG, it is determined that the SCG is successfully activated or that scheduling may be started, further for example: in case the TAT is stopped or not running, it is determined that the SCG is successfully activated or scheduling may be started.

And when the first message is sent, the terminal is instructed to perform preference information of at least one of RLM, BFD and RRM measurements, so as to avoid that the measurement result is unreliable or the performance of other cards is affected when the terminal cannot perform RLM, BFD, RRM measurements during SCG deactivation, thereby improving the communication performance of the terminal.

As an optional implementation manner, the terminal sends the first message according to the first mode, including:

the terminal sends the first message according to the first mode if at least one of the following conditions is met:

the first message is sent for a first purpose, the first purpose being related to multi-card operation;

and receiving first indication information sent by a network side, wherein the first indication information is used for indicating permission or requirement of the terminal to send the first message according to the first mode.

Wherein, the multi-card operation may include: at least part of the capabilities of the SCG are occupied by other cards and/or at least part of the capabilities of the SCG are not occupied by other cards. For example: at least part of the capabilities of the SCG of card a are occupied by card B, and at least part of the capabilities of the SCG of card a are not occupied by other cards. Sometimes for simplicity of description, it may also be simply indicated for the first purpose as for multi-card purposes (for MUSIM purpose).

For example: the prohibit timer may be omitted when the terminal indicates to the network side that its own SCG capability is available for the first purpose, or the prohibit timer may not be started when the terminal requests to deactivate the SCG from the network side for the first purpose, or the SCG deactivation request is due to multi-card operation, where the set duration of the prohibit timer does not exceed a first preset value, that is, only a part of the values may be configured.

If the prohibit timer is running when the terminal sends the first message to the network side for other purposes (e.g. power saving), the terminal waits for the prohibit timer to timeout and then sends the first message.

The first purpose may also be subdivided into performing different tasks on other cards, such as measurement, voice, data, signaling, etc., then in some embodiments the terminal may send in a first manner if the terminal sends the first message for the first purpose, if the first purpose is related to a preset service of the other card, and not in a first manner if the first purpose is not related to a preset service of the other card, i.e. the terminal is to send when the prohibit timer is not running.

In this embodiment, it may be achieved that the first indication information is transmitted in the first manner described above in case the first indication information is for the first purpose and/or received.

In some embodiments, the terminal may send the first message to the network side immediately if SCG capability is available.

In some embodiments, the terminal may send indication information to the network side device, where the indication information may indicate that SCG capability is available, for example, a field SCG capability (SCG capability) = { restriction, no restriction }, where the restriction indicates a restriction, and the no restriction indicates an unrestricted restriction.

As an alternative embodiment, the SCG deactivation preference information includes at least one of:

the SCG is expected to be deactivated or the SCG is not expected to be deactivated;

no SCG deactivation preference;

the SCG is expected to be activated;

the SCG capabilities are no longer limited or the SCG capabilities are limited.

Wherein the undesired deactivation of the SCG may comprise no longer being desired.

The above-mentioned absence of the SCG deactivation Preference may be indicated by a Preference, non-Preference, no Preference, etc. in SCG deactivation Preference information (SCG-DeactivationPreference). The non-preferred and no reference are understood to mean that SCG may be activated or deactivated by the network side, or that the terminal indicates that the preferred SCG is deactivated before the terminal indicates that the preferred SCG is not deactivated any more.

For example, in one embodiment, step 1: the terminal sends an SCG deactivation request, starts a prohibition timer, and step 2: if the terminal wants to indicate to the network side that SCG capability is available for the first purpose (e.g., MUSIM purposise) and the terminal is configured to allow transmission of the assistance information, the terminal transmits to the network side an SCG deactivation preference (SCG-DeactivationPreference) regardless of whether an SCG deactivation preference prohibit timer (SCG-DeactivationPreference timer) is running, wherein the value is set to no preference (noPreference).

The SCG capability is not limited any more, which may mean that the SCG may be activated or deactivated by the network side, and the SCG capability limitation may be that part or all of the SCG capability is limited, where in the case that part of the capability is limited, the SCG may be activated or deactivated by the network side, or some functions may be deactivated, or some resources may be released.

In this embodiment, the preference information may enable the network side device to activate or deactivate the SCG of the terminal based on the preference of the terminal, so as to optimize control of the network side, such as the network side device configuring the terminal with measurement during SCG deactivation, or activating the SCG when SCG downlink data arrives.

Optionally, in case the first message indicates that the terminal desires that the SCG is deactivated, the prohibit timer is not started.

In this embodiment, it may be achieved that the prohibit timer is not started in case it is desired that the SCG is deactivated, so that the terminal may update the SCG deactivation preference information in time later if the SCG of the terminal is available, such as indicating in time that the SCG is no longer desired to be deactivated.

For example: in one embodiment, step 1: the terminal requests the SCG to be deactivated for the first purpose, and the prohibition timer is not started after the terminal sends the SCG deactivation request; step 2: and when the SCG capability of the card is available, the terminal sends SCG-deactivationreference to the network side, and the value is set as non-reference.

Optionally, the terminal realizes that the setting duration of the prohibit timer does not exceed the first preset value by at least one of the following ways:

when the duration configuration information of the prohibit timer is received and exceeds the first preset value, the terminal defaults the duration of the prohibit timer to be the first preset value when sending the first message;

Receiving second indication information, wherein the second indication information is specially used for indicating the duration of a prohibition timer used when the terminal sends the first message to a network side for a first purpose, the first purpose is related to multi-card operation, and the duration does not exceed the first preset value;

and after the first message is sent, receiving reconfiguration information of the duration of the forbidden timer, wherein the reconfiguration information reconfigures the set duration of the timer to a value which does not exceed the first preset value.

When the terminal sends the first message, defaulting the duration of the prohibit timer to the first preset value may be that the terminal actively determines the duration of the prohibit timer to the first preset value when sending the first message, without adopting the value configured by the duration configuration information, so as to send the first message in time.

The duration of the prohibit timer indicated by the second indication information does not exceed a first preset value, so that the terminal can send the first message in time through the second indication information.

The reconfiguration information may be configured to reconfigure the duration of the prohibit timer to a value not exceeding the first preset value, so as to implement timely sending of the first message.

For example: in one embodiment, the second indication information may be SCG-deactivationPreference ProhibitTimerForMuSIM-r18, or the reconfiguration information may be SCG-deactivationPreference Config-r17, where:

in this embodiment, the SCG deactivation preference configuration (SCG-DeactionPrefereConfig) may include:

the configuration of the terminal is used to indicate the terminal's preference for SCG deactivation (Configuration of the UE to indicate its preference for SCG deactivation).

The SCG deactivation preference prohibit timer may be configured as follows:

the prohibit timer is used by the terminal to indicate the SCG deactivation preference, a value in seconds. The value s0 indicates that the prohibit timer is set to 0seconds, the value s1 indicates that the prohibit timer is set to 1second, and so on. If the terminal requests SCG deactivation for MUSIM purposes, an excessive value, e.g. a value of not more than 10s, should be avoided. (Prohibit timer for UE indication of its preference for SCG deactivation. Value in seconds. Values s0 means prohibit timer is set to 0seconds,value s1 means prohibit timer is set to 1second and so on.If SCG deactivation is requested by the UE for MUSIM purpose,the value longer than 10s shall be avoided.)

As an optional implementation manner, the controlling the running state of the SCG related time synchronization timer TAT includes:

generally, if the TAT is running, the upstream is considered to be in a synchronous state, and if the TAT is not started or has timed out, the upstream is considered to be out of step. When the terminal receives the SCG deactivation command, the terminal keeps the TAT of the SCG in an operation state, so that when the SCG is activated, if the uplink is out of step (the TAT is not operated), the terminal needs to execute a random access process to acquire uplink synchronization, and if the uplink is synchronous (the TAT is operating), the terminal does not need to execute random access, and can directly start monitoring the PDCCH to receive the scheduling of the auxiliary base station. This scheme is also called an SCG activation scheme based on omitted RACH (RACH-less)

And stopping the TAT under the condition that an SCG deactivation command or third indication information is received, wherein the third indication information is used for indicating the terminal to stop the TAT.

In this embodiment, the TAT is stopped when the SCG deactivation command or the third indication information is received, so that the terminal cannot execute the RACH-less based activation mode when the SCG is activated, that is, the terminal must send the random access on the PSCell due to the TAT timeout when the SCG activation command is received. In this way, under the condition of multi-card operation, after the secondary base station receives the uplink signal (random access) actively transmitted by the terminal on the PSCell after activating the SCG, it can be determined that the SCG of the terminal is available (because if the SCG capability is occupied by other cards, the terminal is difficult to transmit random access at this time), so that state synchronization is achieved between the secondary base station and the terminal.

For example: in one embodiment, step 1: the terminal requests the network side to deactivate SCG; step 2: the terminal receives the SCG deactivation command, and if the SCG deactivation command is used for responding to the SCG deactivation request of the terminal based on the first purpose, the terminal executes SCG deactivation and stops SCG TAT.

As an optional implementation manner, the controlling the random access operation of at least one serving cell of the SCG when receiving the SCG activation command includes:

under the condition that an SCG activation command is received, a terminal initiates random access of at least one service cell of the SCG; or alternatively, the process may be performed,

and when the SCG activation command is received and fourth indication information is not received, the terminal determines that the configuration is wrong, and the fourth indication information is used for triggering the terminal to execute random access on at least one service cell of the SCG.

The performing of the random access may be initiating a physical random access channel (Physical Random Access Channel, RACH).

In this embodiment, since the terminal initiates the random access of the at least one serving cell of the SCG when receiving the SCG activation command, the network side may determine whether the SCG of the terminal is actually available through whether the random access of the at least one serving cell of the SCG is performed when the SCG is activated, that is, if the random access of the at least one serving cell of the SCG is performed, it is determined that the SCG is actually available, otherwise, it is determined that the SCG is not available. In this way, the random access of at least one service cell of the SCG can indicate that the SCG of the terminal is available, so that the network side equipment can communicate with the terminal in the SCG to improve the communication performance of the terminal.

For example: in one embodiment, in a radio resource control (Radio Resource Control, RRC) reconfiguration procedure, the terminal performs reconfiguration first, and then sends a reconfiguration complete message, and initiates a PSCell RACH if it is determined that a PSCell RACH is required. In this way, the network side device can determine whether the SCG of the terminal is actually available by whether RACH is performed when the SCG is activated.

In this embodiment, in the case that the terminal receives the SCG activation command, the terminal indicates that SCG is not available to the network side before, or indicates that SCG deactivation is requested to the network side before for the first purpose described above. Where here the previous may be a predefined time range before receipt of the SCG activation command.

Wherein the absence of an indirect indication in the SCG state (SCG-state) is to activate the SCG, which in this case is also understood to carry an SCG activation command.

As an alternative embodiment, the terminal performs preference information of at least one of RLM, BFD, and RRM measurement, including at least one of:

request the network side to configure or not configure RLM during SCG deactivation;

requesting the network side to configure or not configure BFD during SCG deactivation;

the network side is requested to configure or not configure RRM measurements during SCG deactivation.

The request network side can configure RLM, BFD and RRM measurements to enable the high-capability terminal to perform necessary measurements to ensure that SCG can be activated quickly and stably later, and the request network side does not configure RLM, BFD and RRM measurements to enable the low-capability terminal to indicate to the network side when the measurement cannot be performed, thereby avoiding being configured with the measurements.

For example: in one embodiment, step 1: the terminal requests the network side to deactivate the SCG, and indicates that the request is for the first purpose, or the network side is not configured with at least one of RLM, BFD and RRM during SCG deactivation; step 2: the terminal receives the SCG deactivation command and indication information, determines that at least one of RLM, BFD and RRM is not performed during SCG deactivation, and the indication information is used for indicating the terminal to delete the saved configuration information for indicating the terminal to perform at least one of RLM, BFD and RRM during SCG deactivation.
