## Abstract

A method is provided by a wireless device for performing reconfiguration and/or resumption of a radio resource control, RRC, connections while operating in a Multi-RAT Dual Connectivity, MR-DC or standalone New Radio, NR, environment. The method includes suspending the wireless device to an inactive mode. The method further includes resuming operation of the wireless device from the inactive mode. The method further includes receiving an indication to perform one of: releasing a master cell group and perform a configuration on at least one of one or more radio bearer configurations and a secondary cell group configuration; or releasing configurations for a master cell group and a secondary cell group and perform the configuration on one or more radio bearer configurations.

## Claims

### Claim 1

A method performed by a wireless device for performing reconfiguration and/or resumption of a radio resource control connections while operating in a Multi-Radio Access Technology Dual Connectivity environment, the method comprising:
suspending the wireless device to an inactive mode;
resuming operation of the wireless device from the inactive mode;
receiving an indication to perform one of:
releasing a master cell group and perform a configuration on at least one of one or more radio bearer configurations and a secondary cell group configuration; or
releasing configurations for a master cell group and a secondary cell group and perform a configuration on one or more radio bearer configurations; and
responsive to receiving the indication to release configurations for the master cell group and the secondary cell group and perform configuration on the one or more radio bearer configurations:
releasing the configurations for the master cell group and the secondary cell group; and
performing configuration on the one or more radio bearer configurations.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
responsive to receiving the indication to release the master cell group and perform the configuration on the at least the one or more radio bearer configurations and the secondary cell group configuration:
releasing the master cell group; and
performing the configuration on the at least one of the one or more radio bearer configurations and the secondary cell group configuration.

### Claim 3 (depends on 2)

The method of claim 2, further comprising:
performing a cell group configuration for a new master cell group responsive to releasing the master cell group.

### Claim 4 (depends on 1)

The method of claim 1, further comprising:
performing a cell group configuration for a new master cell group responsive to releasing the master cell group.

### Claim 5 (depends on 1)

The method of claim 1, further comprising:
receiving a reconfiguration indication to release a master cell group and perform a configuration on one or more radio bearer configurations; and
responsive to receiving the reconfiguration indication:
releasing the master cell group and the secondary cell group; and
performing the configuration on the one or more radio bearer configurations.

### Claim 6 (depends on 5)

The method of claim 5, further comprising:
performing a cell group configuration for a new master cell group responsive to releasing the master cell group.

### Claim 7

A wireless device configured to operate in a communication network, the wireless device comprising:
processing circuitry; and
memory coupled with the processing circuitry, wherein the memory includes instructions that when executed by the processing circuitry causes the wireless device to perform comprising:
suspending the wireless device to an inactive mode;
resuming operation of the wireless device from the inactive mode;
receiving an indication to perform one of:
releasing a master cell group and perform a configuration on at least one of one or more radio bearer configurations and a secondary cell group configuration; or
releasing configurations for a master cell group and a secondary cell group and perform a configuration on one or more radio bearer configurations, and
responsive to receiving the indication to release configurations for the master cell group and the secondary cell group and perform configuration on the one or more radio bearer configurations:
releasing the configurations for the master cell group and the secondary cell group; and
performing configuration on the one or more radio bearer configurations.

### Claim 8

A non-transitory storage medium including program code to be executed by processing of a wireless device configured to operate in a communication network, whereby execution of the program code the wireless to perform operations comprising:
suspending the wireless device to an inactive mode;
resuming operation of the wireless device from the inactive mode;
receiving an indication to perform one of:
releasing a master cell group and perform a configuration on at least one of one or more radio bearer configurations and a secondary cell group configuration; or
releasing configurations for a master cell group and a secondary cell group and perform a configuration on one or more radio bearer configurations, and
responsive to receiving the indication to release configurations for the master cell group and the secondary cell group and perform configuration on the one or more radio bearer configurations:
releasing the configurations for the master cell group and the secondary cell group; and
performing configuration on the one or more radio bearer configurations.

### Claim 9 (depends on 8)

The non-transitory storage medium of claim 8, the operations further comprising:
responsive to receiving the indication to release the master cell group and perform the configuration on the at least the one or more radio bearer configurations and the secondary cell group configuration:
releasing the master cell group; and
performing the configuration on the at least one of the one or more radio bearer configurations and the secondary cell group configuration.

### Claim 10 (depends on 8)

The non-transitory storage medium of claim 8, the operations further comprising:
performing a cell group configuration for a new master cell group responsive to releasing the master cell group.

### Claim 11 (depends on 8)

The non-transitory storage medium of claim 8, the operations further comprising:
performing a cell group configuration for a new master cell group responsive to releasing the master cell group.

### Claim 12 (depends on 8)

The non-transitory storage medium of claim 8, the operations further comprising:
receiving a reconfiguration indication to release a master cell group and perform a configuration on one or more radio bearer configurations; and
responsive to receiving the reconfiguration indication:
releasing the master cell group and the secondary cell group; and
performing the configuration on the one or more radio bearer configurations.

### Claim 13 (depends on 12)

The non-transitory storage medium of claim 12, the operations further comprising:
performing a cell group configuration for a new master cell group responsive to releasing the master cell group.
