RADIO COMMUNICATION APPARATUS, RADIO COMMUNICATION SYSTEM, AND BASE STATION EQUIPMENT

摘要

Radio communication apparatus, radio communication system, and base station equipment that effectively utilize the network resources of both an ad hoc network and a mobile communication network to increase the efficiency of and optimize the networks, thereby improving the communication capacity and throughput of the networks as a whole. The radio communication apparatus (UE1) employs TDD-CDMA system for communication with a base station (30) of the mobile communication network, and also employs the TDD-CDMA system, which is common to the base station, for communication with other radio communication apparatuses in the ad hoc network, thereby using the same frequency band. Communication paths for communicating with the base station equipment include a first communication path for directly communicating with the base station and a second communication path for communicating with the base station equipment via another radio communication apparatus (UE2, UE3 or the like) in the ad hoc network. The radio communication apparatus (UE1) uses one of those communication paths, which is designated by the base station equipment, to communicate with the base station equipment.
