An electronic apparatus (100, U1) in a wireless communication system, comprising: circuitry (110, 120) configured to, perform dual-connection communication with two connection nodes respectively via different carriers; detect a radio link failure on at least one carrier of the second node; and generate a report indicating the radio link failure to the first node; wherein, the circuitry is further configured to, in a case that at least one carrier of one node of the two connection nodes satisfies a condition for triggering report of an A3, A4, A5, B1 or B2 event, in a case that at least one carrier of the other node of the two connection nodes satisfies a condition for triggering report of an A3, A4, A5, B1 or B2 event, after having determined a priority order for reporting, perform measurement result report corresponding to a mode of maintaining connection to one of the dual connection nodes, and transferring connection of at least one node to a third node, to maintain a dual connection state; wherein, determining the priority order for reporting based on one or more of the following principles, the one having a worse channel quality of source node is prior; the one having a better signal of target node is prior; a coverage-based measurement event is prior to a load-based measurement event; a node whose T310 timer expires earlier is prior; and a macro base station node is prior to a low power node. circuitry (110, 120) configured to, perform dual-connection communication with two connection nodes respectively via different carriers; detect a radio link failure on at least one carrier of the second node; and generate a report indicating the radio link failure to the first node; wherein, the circuitry is further configured to, in a case that at least one carrier of one node of the two connection nodes satisfies a condition for triggering report of an A3, A4, A5, B1 or B2 event, in a case that at least one carrier of the other node of the two connection nodes satisfies a condition for triggering report of an A3, A4, A5, B1 or B2 event, after having determined a priority order for reporting, perform measurement result report corresponding to a mode of maintaining connection to one of the dual connection nodes, and transferring connection of at least one node to a third node, to maintain a dual connection state; in a case that at least one carrier of one node of the two connection nodes satisfies a condition for triggering report of an A3, A4, A5, B1 or B2 event, in a case that at least one carrier of the other node of the two connection nodes satisfies a condition for triggering report of an A3, A4, A5, B1 or B2 event, after having determined a priority order for reporting, perform measurement result report corresponding to a mode of maintaining connection to one of the dual connection nodes, and transferring connection of at least one node to a third node, to maintain a dual connection state; wherein, determining the priority order for reporting based on one or more of the following principles, the one having a worse channel quality of source node is prior; the one having a better signal of target node is prior; a coverage-based measurement event is prior to a load-based measurement event; a node whose T310 timer expires earlier is prior; and a macro base station node is prior to a low power node.
