Claim 11:
12. A communication method in an information processing apparatus, the communication method comprising:
controlling to transmit mapping information to subordinate wireless terminals connected to the information processing apparatus, wherein
the information processing apparatus serves as a first base station, and
the mapping information associates identifiers of the subordinate wireless terminals of the first base station to restrictive identifiers of terminals, of the subordinate wireless terminals, connected to the first base station;

controlling to receive, from the subordinate wireless terminals connected to the first base station, a first frame that includes first schedule information associated with first scheduled communication of a 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;

controlling to determine second schedule information associated with the first base station based on information held by the first base station and the first schedule information associated with the second base station, wherein 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;
controlling to transmit a second frame that includes the second schedule information associated with second scheduled communication of the first base station, wherein
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;

controlling to set a random waiting time based on a collision avoidance mechanism; and
controlling to transmit the second trigger frame to the subordinate wireless terminals of the first base station after expiry of the random waiting time.
