Abstract
A network node, operating as a secondary node (SN) for a user equipment (UE) communicating in dual connectivity (DC) with a master node (MN) and the SN, can implement a method for managing deactivation and activation of a secondary cell group (SCG). The method includes detecting (2302) a first indication that an activation status of the SCG is to change, and changing (2304) the activation status at the SN in response to the detecting. Further, the method includes reactivating or releasing (2306) the SCG in response to detecting a second indication related to the SCG.
Claims21
A method implemented in a network node, operating as a secondary node (SN) for a user equipment (UE) communicating in dual connectivity (DC) with a master node (MN) and the SN, for managing deactivation and activation of a secondary cell group (SCG), the method comprising:
- detecting a first indication that an activation status of the SCG is to change;
- changing the activation status at the SN in response to the detecting;
- reactivating or releasing the SCG in response to detecting a second indication related to the SCG;
- and
- resetting or retaining at least one parameter of a protocol layer at or below a radio link control layer in response to changing the activation status or reactivating the SCG.
A network node of a radio access network (RAN) including processing hardware and configured to operate as a secondary node (SN) for a user equipment (UE) communicating in dual connectivity (DC) with a master node (MN) and the SN, the network node configured to:
- detect a first indication that an activation status of a secondary cell group (SCG) is to change,
- change the activation status at the SN in response to the detecting,
- reactivate or release SCG in response to detecting a second indication related to the SCG, and
- reset or retain at least one parameter of a protocol layer at or below a radio link control layer in response to changing the activation status or reactivating the SCG.
A method implemented in a user equipment (UE), communicating in dual connectivity with a RAN via a master node (MN) and a secondary node (SN), for managing deactivation and activation of a secondary cell group (SCG), the method comprising:
- detecting a first indication that an activation status of the SCG is to change;
- changing the activation status at the UE in response to the detecting;
- reactivating the SCG in response to detecting a second indication related to the SCG;
- and
- resetting at least one parameter of a protocol layer at or below a radio link control layer in response to reactivating the SCG.
