Broadcasting method for sending signal containing predetermined information and radio apparatus

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.

主权项

1. A terminal apparatus, comprising:
a receiving unit configured to receive information on a frame that contains at least a plurality slots from an access control apparatus for controlling communications between a plurality of terminal apparatuses, the access control apparatus not being directly involved in data communication between terminal apparatuses and not directly specifying a slot to be used in the data communication; a generator configured to generate a frame that contains at least a plurality of slots in such a manner as to synchronize with the frame corresponding to the information received by said receiving unit; an estimation unit configured to estimate empty slots in the plurality of slots generated by said generator; a selection unit configured to select at least one of the empty slots estimated by said estimation unit without broadcasting data subsequent to estimation of the empty slots by the estimation unit; and a broadcasting unit configured to broadcast data using the slot selected by said selection unit.
