摘要： It is specified in a manner such that a frame containing a first period formed by a plurality of slots and a second period having a predetermined length is repeated. A detecting unit detects a slot, which is usable for the communications between a plurality of other terminal apparatuses, from among a plurality of slots in the first period of a frame containing the first period and the second period. A modem unit and an RF unit broadcast information on the detected slot.

摘要： A processing unit generates timing information on timing, with which each of radio apparatuses is to synchronize in communication between the radio apparatuses when each of the radio apparatus broadcasts a signal, to control the communication between the radio apparatuses. A modem unit and the like broadcast the thus generated timing information. An RF unit and the like receive a signal which is synchronous with the timing information broadcast by them. When a signal which is asynchronous with the timing information and when the duration of this signal continues for a period longer than a first threshold value and the quality of this signal is more deteriorated than a second threshold value, a decision unit detects that the received signal is a disturbing signal. The modem unit and the like also broadcast to the effect that the disturbing signal has been detected.

摘要： A control information extraction unit receives information on a frame that contains at least a plurality slots from an access control apparatus for controlling communications between radio apparatuses. The control information extraction unit generates a frame that contains at least a plurality of slots in such a manner as to synchronize with the frame corresponding to the received information. An estimation unit (82) estimates empty slots in the plurality of slots generated. A selection unit selects, at random, at least one of the estimated. A modem unit and the like broadcast data using the selected slot.
