<p>A radio communication apparatus and a radio communication apparatus can reduce a communication bandwidth required to manage topology maps, can control transmission and reception timings of information for managing the topology maps, and can prevent the information from being broken by collision. The radio communication apparatus includes means (14) for requesting topology map data which is bit field data formed on the basis of a communication state between the terminals and the constituent terminal list and which indicates the communication state between the terminals at the present viewed from the corresponding terminal from the designated terminal, means (3) receiving the request of the topology map data, means (10) for deciding whether the request of the topology map data is for its own terminal or not, means (13) for, when the request of the topology map data is for its own terminal, transmitting the topology map data viewed from its own terminal, and means (11) for, when the request of the topology map data is not for its own terminal, receiving topology map data transmitted from another terminal from which topology map data is requested to reflect the topology map data on the communication state between the terminals stored in its own terminal. <IMAGE></p> |
