User equipment terminal, base station and control information transmission method
A user equipment terminal for transmitting control information to a base station according to a single carrier scheme includes a wideband control information generating unit configured to generate wideband control information for a whole system band or a portion thereof; a frequency-selective control information generating unit configured to generate frequency-selective control information; and a control unit configured to control the wideband control information to be transmitted on a control channel or a data channel and control the frequency-selective control information to be transmitted on the data channel.
1. A user equipment terminal, comprising:
a first transmitting unit configured to transmit, on a control channel, CQI information which is to be periodically transmitted,
wherein resource blocks at both ends of plural resource blocks making up a system band are available for transmission on the control channel and resource blocks between the resource blocks available for transmission on the control channel are available for transmission on a data channel; and
a second transmitting unit configured to transmit, on the data channel, CQI information which is to be non-periodically transmitted.
2. The user equipment terminal as claimed in claim 1 ,
wherein the first transmitting unit transmits, on the control channel, wideband CQI information; and
wherein the second transmitting unit transmits, on the data channel, CQI information on a frequency block basis, wherein the system band is divided into plural frequency blocks.
3. The user equipment terminal as claimed in claim 1 , further comprising:
a control unit configured to control wideband CQI information and frequency-selective CQI information to be transmitted on the data channel, when the wideband CQI information and the frequency-selective CQI information are transmitted at a same timing,
wherein the system band is divided into plural frequency blocks and the frequency-selective CQI information is formed on a frequency block basis.
4. A transmission method, comprising the steps of:
transmitting, on a control channel, CQI information which is to be periodically transmitted, wherein resource blocks at both ends of plural resource blocks making up a system band are available for transmission on the control channel and resource blocks between the resource blocks available for transmission on the control channel are available for transmission on a data channel; and
transmitting, on the data channel, CQI information which is to be non-periodically transmitted.
5. A communication system including a user equipment terminal and a base station apparatus, the user equipment terminal comprising:
a first transmitting unit configured to transmit to the base station apparatus, on a control channel, CQI information which is to be periodically transmitted,
wherein resource blocks at both ends of plural resource blocks making up a system band are available for transmission on the control channel and resource blocks between the resource blocks available for transmission on the control channel are available for transmission on a data channel; and
a second transmitting unit configured to transmit to the base station apparatus, on the data channel, CQI information which is to be non-periodically transmitted.
