MOBILE COMMUNICATION METHOD AND RELAY NODE
First Claim
1. A mobile communication method, comprising:
- a step A of performing, by a radio base station, scheduling such that a first downlink signal is transmitted to a relay node at a first timing;
a step B of performing, by the relay node, scheduling such that a second downlink signal is transmitted to a mobile station at a second timing;
a step C of determining, by the relay node, whether it is necessary to perform scheduling at the second timing such that the second timing does not overlap the first timing in a time direction, based on a first operating frequency used in a radio zone between the relay node and the mobile station and a second operating frequency used in a radio zone between the radio base station and the relay node; and
a step D of notifying, by the relay node, the radio base station of the determination result.

Abstract
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.

6. A relay node, which can set a connection between a radio base station and the relay node, the relay node comprising:
-
a reception unit configured to receive a first downlink signal transmitted from the radio base station at a first timing; a scheduling unit configured to perform scheduling such that a second downlink signal is transmitted to a mobile station at a second timing; a determination unit configured to determine whether it is necessary to perform scheduling at the second timing such that the second timing does not overlap the first timing in a time direction, based on a first operating frequency used in a radio zone between the relay node and the mobile station and a second operating frequency used in a radio zone between the radio base station and the relay node; and a transmission unit configured to notify the radio base station of the determination result. - View Dependent Claims (7, 8, 9, 10)
