In response to the activation state of the target candidate cell group indicated by the activation or deactivation configuration being "activated", activating the target candidate cell group based on the configuration identification of the target candidate cell group, and making the cell group type of the activated target candidate cell group the same as the cell group type of the cell group transmitting the indication information;

illustratively, in one embodiment of the present disclosure, it is assumed that the configuration information of the candidate cell and/or candidate cell group configured by the network device to the UE through the RRC message is: MCG candidate cell group list and SCG candidate cell group list. The MCG candidate cell group list includes two candidate cell groups, the configuration identifiers of the two candidate cell groups are 1 and 2, respectively, and the SCG candidate cell group list includes 2 candidate cell groups, the configuration identifiers of the two candidate cell groups are 1 and 2, respectively. At this time, if the indication information obtained by the UE indicates that the activation state of the candidate cell with the configuration identifier of "1" is "activated", when the indication information is received by the UE through the cell with the configuration identifier of "1" in the MCG candidate cell group list, the UE may activate the candidate cell group with the configuration identifier of "1" in the MCG candidate cell group list, and deactivate the MCG-3 transmitting the indication information at the same time, so as to ensure that the number of pcells with the activation state of "activated" is 1.

In summary, in the cell activation method provided in the embodiments of the present disclosure, the UE may first obtain indication information sent by the network device, where the indication information may be used to indicate an activation or deactivation configuration of at least one target candidate cell and/or target candidate cell group, and then activate or deactivate the at least one target candidate cell and/or target candidate cell group based on the activation or deactivation configuration indicated by the indication information. It can be seen that, in the embodiments of the present disclosure, the indication message sent by the UE through the network device may indicate the activation status and type of a specific target candidate cell and/or cell group, and based on this activation and/or deactivation of the target candidate cell and/or cell group, it may be possible to implement a change in the status and type of the candidate cell or cell group and make both the UE and the network device aware of the target candidate cell and/or cell group, so that subsequent communications are not negatively affected.

Fig. 4 is a flowchart of a method for activating a cell, which is provided in an embodiment of the present disclosure, and the method is executed by a UE, as shown in fig. 4, and the method for activating a cell may include the following steps:

step 401, obtaining indication information sent by a network device, where the indication information may be used to indicate an activation or deactivation configuration of at least one target candidate cell and/or a target candidate cell group, where the activation or deactivation configuration includes a target cell type corresponding to the target candidate cell and/or a target cell group type corresponding to the target candidate cell group.

configuration identification of the target candidate cell;

It can be seen from the above that, in the present embodiment, the activation or deactivation configuration does not include the activation states of the target candidate cell and the target candidate cell group.

Step 402, activating or deactivating at least one target candidate cell and/or target candidate cell group based on the activation or deactivation configuration indicated by the indication information.

Wherein, in one embodiment of the present disclosure, activating at least one target candidate cell based on the indication information comprises:

the target candidate cell is activated based on the configuration identification of the target candidate cell, and the cell type of the activated target candidate cell is made the target cell type.

Illustratively, in one embodiment of the present disclosure, the activation or deactivation configuration indicated in the indication information acquired by the UE includes: the target cell type corresponding to the target candidate cell-1 is PCell.

And, in one embodiment of the present disclosure, the activating at least one target candidate cell group based on the indication information includes:

the target candidate cell group is activated based on the configuration of the target candidate cell group, and the cell group type of the activated target candidate cell group is made the target cell group type.

Illustratively, in one embodiment of the present disclosure, the activation or deactivation configuration indicated in the indication information acquired by the UE includes: the target cell type corresponding to the target candidate cell group-1 is SCG. The UE may be based on activating the target candidate cell group-1 and making the cell type of the activated target candidate cell group-1 SCG.

Fig. 5 is a flowchart of a method for activating a cell, which is provided in an embodiment of the present disclosure, and the method is executed by a UE, as shown in fig. 5, and the method for activating a cell may include the following steps:

step 501, acquiring a DCI signaling sent by a network device, where the DCI signaling is used to carry indication information.

It should be noted that, in one embodiment of the present disclosure, transmission limitation conditions of the DCI signaling may be agreed. Wherein the transmission constraint may include at least one of:

the transmission resource of the DCI signaling is a dedicated resource of the UE, wherein the dedicated resource can be a UE-specific PDCCH (Physical Downlink Control Channel ) or CORESESEET (Control Resource SET, control resource set) or search space;

the cell transmitting the DCI signaling is PCell;

the cell transmitting the DCI signaling is a PSCell;

the cell group for transmitting DCI signaling is SCG;

the cell group transmitting DCI signaling is MCG.

And, in one embodiment of the present disclosure, the transmission of the DCI signaling should satisfy the above-described transmission constraint, based on which the UE may receive the DCI signaling based on the agreed transmission constraint of the DCI signaling.

For example, if the agreed transmission constraint is: the transmission resource of the DCI signaling is a UE-specific resource, and the UE may receive the DCI signaling on the UE-specific resource.

Step 502, determining an indication method of DCI signaling for activating or deactivating configuration.

Among other things, in one embodiment of the present disclosure, the above indication method for determining DCI signaling for activating or deactivating configuration may include: an indication method of DCI signaling for activating or deactivating configuration is determined based on a configuration and/or protocol convention of a network device.

And, in one embodiment of the present disclosure, the indication method of the DCI signaling for the activation or deactivation configuration may include at least one of:

method a: reserved bits of DCI signaling using existing formats indicate activation or deactivation configurations.

Among other things, in one embodiment of the present disclosure, existing format DCI signaling may include at least one of:

DCI Format 1_0, for example: C-RNTI (Cell-Radio Network Temporary Identifier, cell radio network temporary identifier) or CS-RNTI (Configured Scheduling RNTI, configured scheduling radio network temporary identifier) or MCS (Modulation and Coding Scheme modulation and decoding scheme) -DCI Format 1_0 identified by C-RNTI;

DCI Format 4_1, for example: DCI Format 4_1 identified by G (Group) -RNTI or G-CS-RNTI.

And, in one embodiment of the present disclosure, a method of indicating activation or deactivation configuration using reserved bits of DCI signaling of an existing format may be: indicating configuration identifiers of target candidate cells and/or target candidate cell groups by using a first part of bits in the reserved bits, wherein when bit values corresponding to the first part of bits are different, the configuration identifiers of different target candidate cells and/or target candidate cell groups are indicated; indicating the activation state of the target candidate cell and/or the target candidate cell group by using a second part of bits in the reserved bits, wherein when the bit values corresponding to the second part of bits are different, the activation state of different target candidate cells and/or target candidate cell groups is indicated; and indicating the type of the target candidate cell and/or the target candidate cell group by using a third part of bits in the reserved bits, wherein when the bit values corresponding to the third part of bits are different, the type of different target candidate cells and/or target candidate cell groups is indicated.

For example, taking the target candidate cell as an example (target candidate cell group identity), it is assumed that reserved bits 1-3 of DCI signaling in the existing format are used to indicate the configuration identifier of the target candidate cell, reserved bit 4 is used to indicate the activation state of the target candidate cell, and reserved bits 5-7 are used to indicate the cell type of the target candidate cell. Wherein it can be assumed that: when the bit value corresponding to the reserved bit 1-3 is 001, the configuration identifier "1" is indicated, when the bit value corresponding to the reserved bit 1-3 is 010, the configuration identifier "2" … … is indicated, and so on; when the bit value corresponding to the reserved bit 4 is 1, the activation state is indicated to be deactivated, and when the bit value corresponding to the reserved bit 4 is 0, the activation state is indicated to be activated; when the bit value corresponding to reserved bits 5-7 is 000, the cell type is indicated as "PCell", when the bit value corresponding to reserved bits 5-7 is 001, the cell type is indicated as "PSCell" … …, and so on.

Method b: the existing value redefined for at least one particular domain of DCI signaling in the existing format to indicate an active or inactive configuration.

Wherein different specific domains may be used to indicate different content, such as a first specific domain may be used to indicate a configuration identity of a target candidate cell and/or a target candidate cell group, a second specific domain may be used to indicate an activation state of a target candidate cell and/or a target candidate cell group, and a third specific domain may be used to indicate a type of a target candidate cell and/or a target candidate cell group. And the values of the first, second and third specific domains are the same as the existing values, except that new indication meanings are redefined for the existing values to indicate activation or deactivation of the configuration.

Specifically, when the value corresponding to the first specific domain is a first value, the configuration identifier may be used to indicate a certain configuration identifier of the target candidate cell and/or the target candidate cell group, and when the value corresponding to the first specific domain is a second value, the configuration identifier may be used to indicate other configuration identifiers of the target candidate cell and/or the target candidate cell group, and so on; and when the value corresponding to the second specific domain is the first value, the activation state of the target candidate cell and/or the target candidate cell group can be indicated to be activated, and when the value corresponding to the second specific domain is the second value, the activation state of the target candidate cell and/or the target candidate cell group can be indicated to be deactivated; the method can be used for indicating a certain type of the target candidate cell and/or the target candidate cell group when the value corresponding to the third specific domain is a first value, indicating other types of the target candidate cell and/or the target candidate cell group when the value corresponding to the third specific domain is a second value, and so on.

Among other things, in one embodiment of the present disclosure, a particular domain may be, for example, FDRA (Frequency Domain Resource Allocation ).

Method c: at least one specific field of DCI signaling using an existing format carries a new value different from the existing value of the specific field to indicate activation or deactivation of the configuration.

For example, different specific domains may be used to indicate different content, such as a first specific domain may be used to indicate a configuration identity of a target candidate cell and/or target candidate cell group, a second specific domain may be used to indicate an activation state of a target candidate cell and/or target candidate cell group, and a third specific domain may be used to indicate a type of target candidate cell and/or target candidate cell group. And the first, second and third specific domains are different from the existing values, and can be used to carry new values (e.g., values or combinations of values that are not allowed in the current protocol).

And when the value corresponding to the first specific domain is a first value, the configuration identifier can be used for indicating a certain configuration identifier of the target candidate cell and/or the target candidate cell group, and when the value corresponding to the first specific domain is a second value, the configuration identifier can be used for indicating other configuration identifiers of the target candidate cell and/or the target candidate cell group, and the like; and when the value corresponding to the second specific domain is the first value, the activation state of the target candidate cell and/or the target candidate cell group can be indicated to be activated, and when the value corresponding to the second specific domain is the second value, the activation state of the target candidate cell and/or the target candidate cell group can be indicated to be deactivated; the method can be used for indicating a certain type of the target candidate cell and/or the target candidate cell group when the value corresponding to the third specific domain is a first value, indicating other types of the target candidate cell and/or the target candidate cell group when the value corresponding to the third specific domain is a second value, and so on.

Illustratively, in one embodiment of the present disclosure, it is assumed that the configuration identity of the target candidate cell and/or target candidate cell group is indicated using a carrier identity field in DCI signaling of an existing format, and the activation status of the target candidate cell and/or target candidate cell group is indicated using a HARQ (Hybrid Automatic Repeat reQuest ) number field. When the value of the HARQ number field is 0, the HARQ number field may be used to indicate that the activation state of the target candidate cell and/or the target candidate cell group indicated by the carrier identification field is "activated".

Method d: the activation or deactivation configuration is indicated with DCI signaling in a new format.

For example, different fields of the new DCI signaling may be used to indicate different content, e.g., a first field may be used to indicate a configuration identity of a target candidate cell and/or a target candidate cell group, a second field may be used to indicate an activation state of a target candidate cell and/or a target candidate cell group, and a third field may be used to indicate a type of target candidate cell and/or a target candidate cell group. When the values of the first domains are different, indicating configuration identifiers of different target candidate cells and/or target candidate cell groups; when the values of the second domains are different, indicating the activation states of different target candidate cells and/or target candidate cell groups; when the third field takes on a value, the type of the different target candidate cell and/or target candidate cell group is indicated.

Among other things, in one embodiment of the present disclosure, DCI signaling of a new format includes:

DCI Format 2_x, wherein x is an integer greater than or equal to 8.

Step 503, parsing the DCI signaling to obtain the activated or deactivated configuration based on the indication method of the DCI signaling for the activated or deactivated configuration.

In one embodiment of the present disclosure, when the indication method determined in the step 502 is different, the parsing process in the step is also different.

Specifically, when the indication method determined in the above step 502 is method a, the UE may parse the reserved bits of the DCI signaling to determine the activation or deactivation configuration. For example, assuming that the bit value corresponding to reserved bits 1-3 in the DCI signaling is 010, the bit value corresponding to reserved bit 4 is 0, and the bit value corresponding to reserved bits 5-7 is 000, the UE may determine to activate or deactivate the configuration to: the activation state of the cell with the configuration identifier of "2" is "activated", and the cell type is "PCell".

When the indication method determined in the above step 502 is method b or method c, the UE may parse the specific field of the DCI signaling to determine the activation or deactivation configuration.

When the indication method determined in the above step 502 is method d, the UE may directly parse the DCI signaling of the new format to determine the activation or deactivation configuration.

Step 504, activating or deactivating at least one target candidate cell and/or target candidate cell group based on the activation or deactivation configuration.

The related description of step 504 may be described with reference to the above embodiments, which are not described herein.

Wherein, in an embodiment of the present disclosure, determining whether DCI signaling is used to indicate activation or deactivation configuration may include: determining whether the identification information corresponding to the DCI signaling is specific identification information (such as new RNTI (Radio Network Temporary Identity, radio network temporary identifier)); and when the identification information corresponding to the DCI signaling is specific identification information, determining that the DCI signaling is used for indicating activation or deactivation configuration, otherwise, determining that the DCI signaling is not used for indicating the activation or deactivation configuration.
