1. A method performed by a first network node in a radio access network, the method comprising:
determining to initiate a procedure with a first set of at least one neighboring network node;
responsive to the determining, sending to the first set of at least one neighboring network node a first message comprising timing accuracy information for at least one synchronization source of the first network node on at least one of a per cell basis, a per network node basis, or a per neighboring network node for a cell served by the first network node;
deciding whether dual connectivity with at least one of the first set of at least one neighboring network node and a second set of at least one neighboring network node can be performed based on the received timing accuracy information; and
receiving a second message from the second set of at least one neighboring network node providing timing accuracy information for at least one synchronization source of the second set of at least one neighboring network node,
wherein the providing comprises providing the timing accuracy information for the at least one synchronization source of the second set of at least one neighboring network node on at least one of a per cell basis, a per network node basis, or a per neighboring network node for the cell served by the second set of at least one neighboring network node.
