Abstract:
1. A mobile communication method, comprising: a step A in which, when a predetermined trigger indicating conditions for modifying a connection that is set between a radio base station and a relay node is detected, the radio base station notifies the relay node of a transmission timing of a MBSFN (Multicast Broadcast Single Frequency Network) subframe by a signal for changing a configuration of the connection that is set between the radio base station and the relay node; a step B in which the radio base station performs scheduling such that a downlink signal is transmitted by using a time division multiplexing scheme to the relay node at the transmission timing of the MBSFN subframe; and a step C in which the relay node performs scheduling such that a downlink signal is transmitted by using a time division multiplexing scheme at a timing other than the transmission timing of the MBSFN subframe; wherein the connection is an RRC (Radio Resource Control) connection, and the signal is an “RN (Relay Node) Reconfiguration”.
