Abstract

A method performed by a user equipment, UE, for handling communication in a wireless communication network, providing dual connectivity, DC, communication through a master node using a master cell group, MCG, over a first radio interface between the UE and the master node and through a secondary node using a secondary cell group, SCG, over a second radio interface between the UE and the secondary node. The UE detects a failure associated with the SCG and suspends actions associated with the SCG. The UE further performs a reconfiguration of the SCG in case the UE has received a MCG radio resource control, RRC, message comprising SCG configuration, wherein performing the reconfiguration of SCG comprises applying the reconfiguration; and resuming or not resuming the actions associated with the suspended SCG.

A method performed by a user equipment (UE) for handling communication in a wireless communication network, providing dual connectivity (DC) communication through a master node using a master cell group (MCG) over a first radio interface between the UE and the master node and through a secondary node using a secondary cell group (SCG) over a second radio interface between the UE and the secondary node, the first radio interface using a first radio access technology and the second radio interface using a second radio access technology that is different from the first radio access technology, the method comprising:

detecting a failure associated with the SCG;
suspending SCG transmission over an SCG link;
performing a reconfiguration of the SCG upon reception of an SCG radio resource control (RRC) message with SCG configuration, the SCG RRC message being embedded in an MCG radio resource control, RRC, message, from the master node;
if the embedded SCG RRC message contains mobility information for the SCG link, resuming the SCG transmission over the SCG link;
and
if the embedded SCG RRC message does not contain mobility information for the SCG link, not resuming the SCG transmission.

perform a reconfiguration of the SCG upon reception of an SCG radio resource control (RRC) message with SCG configuration, said SCG RRC message being embedded in an MCG radio resource control, RRC, message, from the master node;
if the embedded SCG RRC message contains mobility information for the SCG link, resuming the SCG transmission over the SCG link;
and
if the embedded SCG RRC message does not contain mobility information for the SCG link, not resuming the SCG transmission.
