Title:
COMMUNICATION SYSTEM, MAIN UNIT, RADIO ACCESS UNIT AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/129102
Kind Code:
A1
Abstract:
Provided is a communication system that can reduce the cost accompanying the system introduction without need to significantly change the existing system structure and that further can ensure a wide range of coverage, while improving the user throughput. In this system, a plurality of radio access units (108-1 to 108-n) form the single cell (#120) of a first communication system, while forming respective individual multi-cells (#130-1 to #130-n) of a second communication system within the single cell (#120). The plurality of radio access units (108-1 to 108-n) transmit a downstream signal of the first communication system input from a main unit (107) to a terminal using the first communication system of the single cell (#120), while each transmitting a downstream signal of the second communication system input from the main unit (107) to a terminal using the second communication system of the corresponding respective one of the multi-cells (#130-1 to #130-n).
