摘要：
A mobile communication method according to the present invention includes a step of transmitting, by a radio base station DeNB, “RA Response” to a mobile station UE within a “RA Response window” for the mobile station UE when “RA Preamble” is received from the mobile station UE, a step of transmitting, by a relay node RN, a signal to the mobile station UE in a subframe other than an MBSFN subframe, and a step of transmitting, by the radio base station DeNB, “RA Response” to the relay node RN in an MBSFN subframe of a “RA Response window” for the relay node RN when “RA Preamble” is received from the relay node RN.
