Mobile station device, communication system, communication method, integrated circuit, and circuit device

A communication method for use in a mobile station device which is configured to or programmed to communicate with a base station device, the communication method comprising:

• generating, as uplink control information,
• a receipt acknowledgement indicating a positive acknowledgement or a negative acknowledgement for downlink data, and
• a scheduling request indicating whether to request said base station device to allocate a radio resource;
• setting a value of a first parameter relevant to transmission power in accordance with a first amount of information of said receipt acknowledgement and said scheduling request;
• setting a second parameter based on a transmission power control command;
• controlling, by means of at least one of said first parameter and said second parameter, the transmission power for a first physical uplink control channel used for transmitting a signal generated based on said receipt acknowledgement and said scheduling request;
• and
• transmitting said first signal to said base station device using said first physical uplink control channel with said controlled transmission power in an uplink subframe in a case that resource of a physical uplink shared channel is not allocated, wherein
• a second amount of information of said scheduling request included in the first amount of information of said receipt acknowledgement and said scheduling request is one bit and said scheduling request is not transmitted using a second physical uplink control channel for said scheduling request in a case that said second physical uplink control channel for said scheduling request is configured in the uplink subframe and the management unit generates said receipt acknowledgement, and
• the second amount of information of said scheduling request included in first the amount of information of said receipt acknowledgement and said scheduling request is zero bit in a case that said second physical uplink control channel for said scheduling request is not configured in the uplink subframe.

A circuit device mountable on a mobile station device to cause said mobile station device to perform a plurality of functions, said circuit device comprising:

• a first circuit configured to or programmed to generate, as uplink control information,
• a receipt acknowledgement indicating a positive acknowledgement or a negative acknowledgement for downlink data, and
• a scheduling request indicating whether to request said base station device to allocate a radio resource;
• a second circuit configured to or programmed to set a value of a first parameter relevant to transmission power in accordance with a first amount of information of said receipt acknowledgement and said scheduling request and configured to and/or programmed to set a second parameter based on a transmission power control command;
• a third circuit configured to or programmed to control, by means of at least one of said first parameter and said second parameter, the transmission power for a first physical uplink control channel used for transmitting a signal generated based on said receipt acknowledgement and said scheduling request;
• and
• a fourth circuit configured to or programmed to transmit said signal to said base station device using said first physical uplink control channel with said controlled transmission power in an uplink subframe in a case that resource of a physical uplink shared channel is not allocated, wherein
• a second amount of information of said scheduling request included in the first amount of information of said receipt acknowledgement and said scheduling request is one bit and said scheduling request is not transmitted using a second physical uplink control channel for said scheduling request in a case that said second physical uplink control channel for said scheduling request is configured in the uplink subframe and the management unit generates said receipt acknowledgement, and
• the second amount of information of said scheduling request included in the first amount of information of said receipt acknowledgement and said scheduling request is zero bit in a case that said second physical uplink control channel for said scheduling request is not configured in the uplink subframe.
