<p>A radio apparatus and base station apparatus that flexibly respond to an increase or decrease in the number of users without being constrained by the number of users. An A-DPCH signal processing section ( 106 ) generates dedicated transmission signals corresponding in number to users multiplexed based on the number of users for each sector input from a control station apparatus and outputs the multiplexed signal to a multiplexing section ( 105 ). An HSDPA signal processing section ( 107 ) selects a transmission destination sector based on an instruction from a base station control section, generates multiplexed transmission data and outputs the multiplexed data to the multiplexing section ( 105 ). The multiplexing section ( 105 ) code-multiplexes dedicated transmission signals of A-DPCH and packet data in HSDPA communication for each sector and outputs the multiplexed data to a radio transmission section ( 104 ). The radio transmission section ( 104 ) transmits the multiplexed transmission signal input from the multiplexing section ( 105 ) from an antenna ( 101 ).</p> |
