Abstract
Official abstract text for this publication.
A base station which is able to perform radio communications with a relay station and a mobile station, the base station includes a transmitter configured to transmit radio signals to the relay station in downlink backhaul subframes, and to limit transmission of radio signals to the relay station in subframes other than the downlink backhaul subframes; and a controller configured to allow, when performing a random access procedure to the relay station, the transmitter to transmit a message of the random access procedure even in the subframes other than the downlink backhaul subframes.
First claim
Opening claim text (preview).
1 . A base station which is able to perform radio communications with a relay station and a mobile station, the base station comprising: a transmitter configured to transmit radio signals to the relay station in downlink backhaul subframes, and to limit transmission of radio signals to the relay station in subframes other than the downlink backhaul subframes; and a controller configured to allow, when performing a random access procedure to the relay station, the transmitter to transmit a message of the random access procedure even in the subframes other than the downlink backhaul subframes. 2 . A radio communication system comprising: a relay station; a mobile station; and a base station which is able to perform radio communications with the relay station and the mobile station, the base station including: a transmitter configured to transmit radio signals to the relay station in downlink backhaul subframes, and to limit transmission of radio signals to the relay station in subframes other than the downlink backhaul subframes; and a controller configured to allow, when performing a random access procedure to the relay station, the transmitter to transmit a message of the random access procedure even in the subframes other than the downlink backhaul subframes.
