Scheduling creation apparatus, base station apparatus, and radio communication method

A base station apparatus comprising:

• an acquisition section that acquires a transmission gap which is a time during which a base station apparatus sends no signal to a corresponding terminal in a compressed mode of an accompanying dedicated physical channel;
• a scheduling section that creates a schedule for sending packet data to a communication terminal apparatus in a time other than the transmission gap in the communication terminal apparatus with the highest priority and sending packet data to another communication terminal apparatus in the transmission gap;
• and
• a transmission section that transmits the packet data using a shared channel through which signals directed to a communication terminal apparatus and assigned by schedule are sent on a per divided time basis according to the schedule, wherein:
• the acquisition section detects power of transmission signals of the accompanying dedicated physical channel and the scheduling section creates the schedule for sending the packet data in times in ascending order of power of the transmission signals preferentially.
