Wireless communication system
A wireless communication method used by a wireless communication apparatus is disclosed. The wireless communication method transmits and receives control information divided into a second control information containing information related to the demodulation and decoding of traffic channel and a first control information containing information related to the MIMO separation of the second control information.
1. A method used by a wireless communication apparatus, comprising:
transmitting from the wireless communication apparatus to another wireless communication apparatus, first control information including control information regarding Multiple Input Multiple Output (MIMO), second control information to which first transmission processing in accordance with a content of the first control information regarding MIMO is applied, and data to which second transmission processing in accordance with the first control information and the second control information is applied,
wherein the content of the first control information specifies whether MIMO mode is to be applied or not, and the second control information includes Hybrid-ARQ process information, redundancy and constellation version information, and transport block size information,
wherein a transmission rate of the second control information is variable.
2. A method according to claim 1 , wherein the transmission rate of the second control information is variable depending on whether MIMO mode is applied or not.
3. A method used by a wireless communication apparatus, comprising:
receiving from another wireless communication, first control information including control information regarding Multiple Input Multiple Output (MIMO), second control information to which first transmission processing in accordance with a content of the first control information regarding MIMO is applied at the another wireless communication apparatus, and data to which second transmission processing in accordance with the first control information and the second control information is applied at the another wireless communication apparatus,
wherein the content of the first control information specifies whether MIMO mode is to be applied or not, and the second control information includes Hybrid-ARQ process information, redundancy and constellation version information, and transport block size information,
wherein a transmission rate of the second control information is variable.
4. A method according to claim 3 , wherein the transmission rate of the second control information is variable depending on whether MIMO mode is applied or not.
