RADIO COMMUNICATION APPARATUS, RADIO COMMUNICATION METHOD, COMMUNICATION CHANNEL ASSIGNING METHOD AND ASSIGNING APPARATUS

摘要

A radio communication apparatus having a function for allowing it to be connected both to an ad hoc network and to a mobile communication network, yet having a structure that is not complicated with cost increases suppressed, and yet being capable of smoothly switching between the networks. The radio communication apparatus (10) uses a TDD-CDMA system for communication with a base station of the mobile communication network, and comprises ad hoc communication means for performing a radio communication with another neighboring radio communication apparatus by making an ad hoc network in conj unction with the other radio communication apparatus. This ad hoc communication means, when communicating with the other radio communication apparatus , uses the TDD-CDMA system common to the mobile communication network.
