Measurement gap configuration in NE-DC and NR-NR DC

A method by a master network node for measurement gap configuration, the method comprising:

• establishing a connection with a wireless device operating in dual connectivity with the master network node and a secondary network node, the master network node operating on a New Radio, NR, wireless network and the secondary network node operating on a Long-Term Evolution, LTE, network, wherein the measurement gap configuration is configured on a per frequency basis for at least a first frequency and a second frequency on the NR wireless network, wherein the measurement gap configuration is configured on a per frequency basis for the first frequency on the LTE network;
• configuring, by the master network node, the wireless device with at least one measurement gap for the second frequency when the master network node configures a measurement that requires the at least one measurement gap
• configuring, by the master network node, the wireless device with at least one measurement gap for the first frequency when the master network node is first to configure a measurement that requires the at least one measurement gap before the secondary network node, and
• receiving, from the secondary network node, a configuration of the at least one measurement gap for the first frequency when the secondary network node is first to configure a measurement that requires the at least one measurement gap for the first frequency before the master network node.
