Zusammenfassung:	A method and network node for dual connectivity for a wireless device are disclosed. According to one aspect, a method in a network node is provided for use in a dual connectivity mode to communicate with wireless devices (WDs), according to a first radio access technology (RAT), and to communicate with WDs according to a second RAT is provided. The method includes scheduling uplink and downlink signals to be transmitted and received by a first set of WDs such that the first set of WDs are operable to: receive downlink signals and transmit uplink (UL) signals using the first RAT only in even Transmission Time Intervals (TTIs) of the first RAT; and transmit uplink signals using the second RAT only in in UL TTIs of the second RAT that do not collide with even TTIs of the first RAT.
