Wireless communication system, apparatus, and method to communicate using a plurality of communication slots in time division multiple access technique

A first wireless communication apparatus, which performs time-division wireless communication with a second wireless communication apparatus, comprising:

• assigning means for assigning a series of data to a plurality of communication slots in a first communication carrier;
• communication means for communicating via the plurality of communication slots, assigned by said assigning means, in the first communication carrier;
• determination means for determining that a communication slot out of the plurality of communication slots is unusable when communication is being performed using the plurality of communication slots by said communication means;
• and
• changing means for, when said determination means determines that a communication slot out of the plurality of communication slots is unusable, changing the communication slot which is determined unusable by said determination means, at least, to another communication slot.

A communication method for a wireless communication system including a first wireless communication apparatus and a second wireless communication apparatus which perform time-division wireless communication, said method comprising:

• an assigning step of assigning a series of data to a plurality of communication slots in a first communication carrier;
• a communication step of communicating via the plurality of communication slots, assigned in said assigning step, in the first communication carrier;
• a determination step of determining that a communication slot out of the plurality of communication slots is unusable when communication is being performed using the plurality of communication slots by said communication step;
• and
• a changing step of, when it is determined in said determination step that a communication slot out of the plurality of communication slots is unusable, making the wireless communication system change the communication slot which is determined unusable in said determination step, at least, to another communication slot.

A communication method for a first wireless communication apparatus, which performs time-division wireless communication with a second wireless communication apparatus, said method comprising:

• a determination step of determining that a communication slot out of the plurality of communication slots is unusable when communication is being performed using the plurality of communication slots by said communication step;
• and
• a changing step of, when it is determined in said determination step that a communication slot out of the plurality of communication slots is unusable, making the wireless communication system change the communication slot which is determined unusable in said determination step, at least, to another communication slot.

A first wireless communication apparatus, which performs time-division wireless communication with a second wireless communication apparatus, comprising:

• assigning means for assigning a series of data to a plurality of communication slots in a first communication carrier;
• communication means for communicating via the plurality of communication slots, assigned by said assigning means, in the first communication carrier;
• reception means for receiving an instruction signal, from the second wireless communication apparatus, indicative of changing a communication slot out of the plurality of communication slots when communication is being performed using the plurality of communication slots by said communication means;
• and
• changing means for changing the communication slot which is instructed to be changed, at least, to another communication slot on the basis of the instruction signal received by said reception means.
