MOBILE COMMUNICATION METHOD AND RADIO BASE STATION

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.

1. A mobile communication method for transmitting and receiving a data signal and a control signal through a radio base station interface between a first mobile station and a second mobile station and a radio base station, and for transmitting and receiving the data signal through an inter-mobile station interface between the first mobile station and the second mobile station, the mobile communication method comprising:
a step A in which the radio base station notifies the first mobile station and the second mobile station that an opportunity to transmit and receive the data signal through the inter-mobile station interface is allocated through a physical downlink control channel in which common identification information is used; and a step B in which the radio base station transmits transmission direction information through RRC signaling, for notifying of a direction in which the data signal should be transmitted in the opportunity, to the first mobile station and the second mobile station.
