Abstract
The present invention relates to a system conducting multi-carrier communications between a base station and a plurality of mobile terminals. When a transmission format of an individual information channel transmitted from the base station to the mobile terminals is output over a control channel from the base station to the mobile terminals, the transmission is conducted over the control channel of the same chunk as the chunk used in the individual information channel.
Claims7
A radio communications system, conducting radio communications between a base station and a plurality of mobile stations, at least the radio communications from the base station to the mobile stations being conducted in a multi-carrier scheme, a transmission format of an individual information channel transmitted from the base station to the mobile stations being output over a control channel,
- the system being wherein the base station comprises:
- first transmission means for transmitting identification information to identify each of the mobile stations, and format information representing the transmission format of an individual information channel, in association with each other, over the control channel;
- and
- second transmission means for transmitting transmission information for the mobile station represented by the identification information, in a transmission format represented by the format information transmitted over the control channel by the first transmission means, over an individual information channel of a frequency band including the control channel transmitted by the first transmission means, and
- that the mobile station comprises:
- first reception means for receiving the identification information and the format information over the control channel;
- and
- second reception means for, if the identification information received by the first reception means is to be transmitted to the own mobile station, receiving the individual information channel of the frequency band including the control channel, in the transmission format represented by the format information received by the first reception means together with the identification information.
A base station apparatus of a radio communications system, conducting multi-carrier radio communications with a plurality of mobile stations, and outputting a transmission format of an individual information channel transmitted to the mobile stations, over a control channel,
- the apparatus being comprising:
- first transmission means for transmitting identification information to identify each of the mobile stations, and format information representing the transmission format of an individual information channel, in association with each other, over the control channel;
- and
- second transmission means for transmitting transmission information for the mobile station represented by the identification information, in a transmission format represented by the format information transmitted over the control channel by the first transmission means, over an individual information channel of a frequency band including the control channel transmitted by the first transmission means.
A mobile radio terminal apparatus, receiving a multi-carrier radio signal from a base station, and being employed in a radio communications system outputting a transmission format of an individual information channel transmitted from the base station over a control channel included in a frequency band of the individual information channel,
- the apparatus being comprising:
- first reception means for receiving the identification information and the format information over the control channel;
- and
- second reception means for, if the identification information received by the first reception means is to be transmitted to the own apparatus, receiving the individual information channel of the frequency band including the control channel, in the transmission format represented by the format information received by the first reception means together with the identification information.
