Abstract
According to some embodiments, a method performed by a wireless device capable of operating in dual connectivity with a first network node in a master cell group (MCG) and a second network node in a secondary cell group (SCG) comprises receiving a connection configuration message from the first network node. The message includes parameters for setup or modification of the SCG. The method further comprises: storing parameters for synchronization or random access with the second network node; operating in dual connectivity with the first and second network nodes; storing configuration information about the second network node received via system information; receiving a connection release message from the first network node; receiving a connection resume message from the first network node; determining the message does not include a new or modified configuration for the SCG; and performing synchronization and random access with the second network node using the stored parameters.
