Abstract: a target secondary node (t-sn) () indicates to a master node (mn) (), in a response message to a request for an inter-sn conditional pscell change (cpc), whether or not all of candidate pscells suggested by the mn () or a source sn (s-sn) () have been accepted. if all of these candidate pscells have been accepted, the mn () sends an mn rrc reconfiguration message to a ue () to instruct the inter-sn cpc while skipping additional signaling with the s-sn () or without waiting for the completion of the additional signaling. otherwise, the mn () sends an mn rrc reconfiguration message to the ue () after additional signaling with the s-sn (). otherwise, the mn () sends an mn rrc reconfiguration message to the ue () after additional signaling with the s-sn (). this prevents, for example, increased delays in the preparation of an sn-initiated inter-sn cpc.
