Claim of US Patent No. 10,397,975

1. A mobile device supporting a dual connectivity, the mobile device communicating with a master evolved NodeB (MeNB) and a secondary evolved NodeB (SeNB) for the dual connectivity, the mobile device comprising:a receiver configured to:
receive, from the MeNB, information including activation/deactivation indicators of secondary serving cells (SCells) in a first SCell group configured for the mobile device; and
receive, from the SeNB, information including activation/deactivation indicators of SCells in a second SCell group configured for the mobile device; and
a processor operationally coupled to the receiver and configured to:
control activation/deactivation states of the SCells in the first SCell group according to the activation/deactivation indicators of the SCells in the first SCell group identified from the information received from the MeNB; and
control activation/deactivation states of the SCells in the second SCell group according to the activation/deactivation indicators of the SCells in the second SCell group identified from the information received from the SeNB,
wherein the mobile device performs communication based on the controlled activation/deactivation states of the SCells in the first SCell group and the controlled activation/deactivation states of the SCells in the second SCell group.
