MOBILE RADIO COMMUNICATION DEVICE

摘要

PURPOSE: To avoid the necessity of small cells and the resulting a result, high cost for a large number of base stations by providing each repeating station having an automatic gain control part and stopping an unnecessary input signal containing an interference signal transmitted from a subscriber device to a base station through the repeating stations. CONSTITUTION: A base station BS communicates with a mobile subscriber device SU through a plural of number of repeating stations R1 and R2. The repeating stations R1 and R2 respectively have directional antennas for communicating with the base station BS and omnidirectional antennas for communicating with nearby subscriber devices. The subscriber device SU communicates with the repeating station R2 by a frequency f1 and when a user moves to a different area, this communication is carried out through the repeating station R1 by using the same frequency. When the subscriber device SU is somewhere between both the repeating stations R1 and R2, the both are used at the same time to relay the same message. Communication between the repeating stations R1 and R2 and base station BS uses a different frequency f2 .
