摘要:
Transmission/reception timing of a data signal and a control signal through a Uu interface and transmission/reception timing of the data signal through a Ud interface are properly adjusted. A mobile communication method according to the present invention includes: a step A in which a radio base station eNB notifies a mobile station UE#1 and a mobile station UE#2 that an opportunity to transmit and receive the data signal through the Ud interface is allocated through a PDCCH in which an X-RNTI is used; and a step B in which the radio base station eNB transmit “direction information”, for notifying of a direction in which the data signal should be transmitted in the opportunity, to the mobile station UE#1 and the mobile station UE#2.

摘要:
Interference to a reception circuit of a relay node itself is reduced, which occurs when transmission-and-reception process in a Un radio bearer and transmission-and-reception process in a Uu radio bearer are simultaneously performed. A mobile communication method according to the present invention includes a step of determining, by a relay node RN, whether it is necessary to perform the scheduling of a second timing such that the second timing does not overlap a first timing in a time direction, based on a first operating frequency f1 used in a radio zone between the relay node RN and a mobile station UE and a second operating frequency f2 used in a radio zone between a radio base station DeNB and the relay node RN, and a step of notifying, by the relay node RN, the radio base station DeNB of the determination result.
