SEGMENTATION FOR COORDINATION AMONG MULTIPLE NODES IN DUAL CONNECTIVITY
A method performed by a first node (111). The method is for handling a message to a third node (113). The message comprises content from at least a first second node (114) of one or more second nodes (112). The first node (111) handles a radio communication with the third node (113) in coordination with the one or more second nodes (112). The first node (111) sends (809) the message to the third node (113), segmented or not segmented. Whether the message is sent segmented or not segmented is based on: i) whether or not a size of the message exceeds a size limit, ii) whether or not the third node (113) supports segmentation of messages, iii) whether or not the first node (111) supports segmentation of messages, and iv) whether or not at least the first second node (114) of the one or more second nodes (112) supports segmentation of messages.
