Claim 12:
13. A wireless terminal subordinate of an information processing apparatus, the wireless terminal subordinate comprising:
circuitry configured to perform:
control to receive mapping information from the information processing apparatus, wherein
the information processing apparatus serves as a first base station,
the mapping information associates identifiers of subordinate wireless terminals of the first base station to restrictive identifiers of terminals, of the subordinate wireless terminals, connected to the first base station, and
the subordinate wireless terminals include the wireless terminal subordinate;

control to transmit the mapping information to a second base station to which the first base station is not connected;
control to transmit, to the first base station, a first frame that includes first schedule information associated with first scheduled communication of the second base station, wherein
the first schedule information includes first information associated with a transmission schedule of a first trigger frame and second information associated with a transmission method of the first trigger frame;

control to receive a second frame that includes second schedule information associated with second scheduled communication of the first base station, wherein
the second schedule information is determined based on information held by the first base station and the first schedule information associated with the second base station,
the information held by the first base station comprises at least one of an attribute of the subordinate wireless terminals, a buffer state of the subordinate wireless terminals, a communication resource state of the subordinate wireless terminals, or a communication result of the subordinate wireless terminals,
the second schedule information includes third information associated with a transmission schedule of a second trigger frame, and
the second scheduled communication of the first base station is based on the second trigger frame; and

control to receive the second trigger frame from the first base station after expiry of a random waiting time set by the first base station, wherein the random waiting time is based on a collision avoidance mechanism.
