PROBLEM TO BE SOLVED: To suppress interferences between systems in home servicing, in code division multiple access(CDMA)/time division duplex(TDD) system adopting a time division multiple access(TDMA) structure. SOLUTION: A signal with a TDMA structure in the CDMA/TDD system is used, and a notice channel is sent/received only through a final outgoing slot of a sub frame to allow the system to cope with various services flexibly, so as to avoid an interference problem especially in a private service. Furthermore, the base communication device makes transmission repeatedly by the number of time division of information included in the notice channel, and assignment of incoming outgoing slots is devised so as to enhance the features of incoming open loop transmission power control and base station transmission diversity. |
