Radio transmitting/receiving apparatus and method, terminal apparatus, base station apparatus and wireless communication system

A wireless communication system comprising:

• a communication apparatus;
• and
• a macrocell base station controlling a macrocell,
• wherein the communication apparatus includes:
• a first receiver, which, in operation, receives, from the macrocell base station, a control message including a network policy regarding handover to femto cells included in the macrocell and receives, from a femto cell base station controlling one of the femto cells, a pilot channel signal for reception quality measurement and a synchronization channel signal for synchronization;
• a storage, which, in operation, stores a list indicative of accessible femto cells among the femto cells included in the macrocell;
• a processor, which, in operation, determines which femto cells are positionally accessible based on the list of the accessible femto cells in reference to the network policy, and creates a report indicative of the positionally accessible femto cells;
• and
• a first transmitter, which, in operation, transmits the created report to the macrocell base station after the first receiver receives the control message including the network policy regarding handover to femto cells included in the macrocell, and
• wherein the macrocell base station includes:
• a second transmitter, which, in operation, transmits the control message including the network policy to the communication apparatus;
• and
• a second receiver which, in operation, receives the report from the communication apparatus.
