摘要

means for storing an identifier indicating a layer 1 control channel accompanying a downlink data channel and a physical channel parameter for transmitting an uplink layer 1 control channel while correlating them to each other; and means for judging the physical channel parameter according to the identifier and generating a layer 1 control channel. A base station includes: storage means; means for measuring reception quality according to a signal transmitted from the mobile station, selecting the physical channel parameter, and generating a layer 1 control channel corresponding to the physical channel parameter; and means for transmitting the layer 1 control channel.
