MOBILE COMMUNICATION METHOD, RELAY NODE, AND WIRELESS BASE STATION

摘要

In order to reduce the interference to a receiver from a relay node (RN) due to simultaneous transmission/reception processing in the Un wireless bearer and the Uu wireless bearer when the relay node (RN) is handed over from a wireless base station (DeNB#1) to another wireless base station (DeNB#2), the handover procedure of the mobile communication method according to the present invention includes a step (A) in which the relay node (RN) uses a "RRC Connection Reconfiguration Complete" message to inform the other wireless base station (DeNB#2) of "Un subframe pattern #1", which expresses the pattern in Un subframe #1, and "RN subframe config req", which indicates whether or not it is necessary to establish Un subframe #2 in the wireless bearer #2 between the other wireless base station (DeNB#2) and the relay node (RN).
