Wireless communication apparatus, wireless communication method, and computer program
First Claim
1. A wireless communication system that is formed with a network among a plurality of wireless communication stations having no relations such as a control station and a station to be controlled each other, wherein:
- each communication station is able to acquire a priority slot with which the communication station itself performs data transmission preferentially at a predetermined time interval; and
each communication station is able to release the priority slot, or to allocate the priority slot to another communication station.

Abstract
Communication bands are effectively allocated to each communication station under a communication environment of an autonomous distributed type system such as an ad-hoc communication. Each communication station acquires a priority slot with which each communication station itself performs data transmission preferentially at predetermined time intervals, and releases or allocates its own priority slot to other communication station in response to a permission form upper layer of a communication protocol based on a fact that the transmission data is not in a buffer. Thereby, it is able to effectively utilize the communication bands, and to improve a throughput of the whole system.

8. A wireless communication apparatus operating under a wireless communication environment, in which communication stations do not have relations such as a control station and a station to be controlled, wherein:
-
communication means for transmitting and/or receiving wireless communication data;
control means for controlling operations for transmitting and/or receiving the wireless communication data by said communication means;
priority slot acquisition means for acquiring the priority slot which the communication station itself performs data transmission preferentially under the wireless communication environment at a predetermined time interval;
priority slot lending means for releasing or allocating its own priority slot to other communication station; and
priority slot borrowing means for borrowing the priority slot of other communication station. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 24, 25, 26)

20. A wireless communication method operating under a wireless communication environment, in which communication stations do not have relations such as a control station and a station to be controlled, comprising the steps of:
-
priority slot acquisition step for acquiring the priority slot which the communication station itself performs data transmission preferentially under the wireless communication environment at a predetermined time interval;
priority slot lending step for releasing or allocating its own priority slot to other communication station; and
priority slot borrowing means for borrowing the priority slot of other communication station. - View Dependent Claims (21, 22, 23, 27, 28, 29, 30)

31. A computer program described in a computer readable form to perform wireless communication processes on a computer system operating under a wireless communication environment, in which communication stations do not have relations such as a control station and a station to be controlled, said computer program comprising the steps of:
-
a priority slot acquisition step of acquiring a priority slot with which each communication station itself performs data transmission preferentially at predetermined time intervals under the above-mentioned wireless communication environment;
a priority slot lending step of releasing its own priority slot or allocating it to another communication station; and
a priority slot borrowing step of using the priority slot of another communication station.
