The present invention relates to a method and embodiments thereof in a Radio Node, a node, computer program and computer program products for adapting of Radio Coordination schemes to transport network characteristics. The method comprises detecting new neighbours, retrieving transport characteristics values between radio neighbours, validity checking of the active Radio Coordination scheme(s), and updating of Radio Coordination scheme, if necessary, based on the measured transport characteristics values.

Method, a node, computer program and computer program product for adapting radio coordination schemes

Determining a time synchronization inaccuracy value between a first node and a second node. A PTP packet is received including Node IDs representing respective transport nodes along a first path, and from the second node Node IDs are obtained representing respective transport nodes along a second path. Furthermore, a first common node of the first path and the second path is determined. The time synchronization inaccuracy value between the first node and the second node is calculated. By including Node IDs in received PTP packets before forwarding them to a node, the node is enabled to determine a first common node. Thereby, the node may calculate relative time inaccuracy values with respect to the other access network nodes, which may be used to decrease inaccuracy time synchronization for co-ordination functions.
