Claim of US Patent No. 10,512,095

1. An apparatus of a user equipment (UE) configured for dual connectivity with a Master evolved Node-B (MeNB) and a Secondary evolved Node-B (SeNB), the apparatus comprising:processing circuitry configured to:
decode downlink traffic packets received from the MeNB and from the SeNB as part of a split data radio bearer (DRB), wherein the split DRB is associated with two radio link control (RLC) entities;
decode a Radio Resource Control (RRC) signaling received from the MeNB, the RRC signalling including a first indicator specifying whether the UE is to transmit uplink traffic packets on a Secondary Cell Group (SCG) supported by the SeNB, and a second indicator specifying a Packet Data Convergence Protocol (PDCP) timer for reordering downlink traffic packets received out of sequence as part of the split DRB; and
based at least partly on the first indicator, encode the uplink traffic packets for transmission to a Master Cell Group (MCG) supported by the MeNB or the SCG as part of the split DRB; and
memory coupled to the processing circuitry, the memory configured to store the first and second indicators.
