Title:
WIRELESS COMMUNICATION SYSTEM, WIRELESS BASE STATION DEVICE, AND MOBILE TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/029873
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a wireless communication system, a wireless base station device, and a mobile terminal device in which duplex communication is efficiently applied in a communication system having a frequency band configured from a plurality of basic frequency blocks. In the wireless communication system, the frequency band allocated to wireless communication between a wireless base station device and a mobile terminal device is configured by adding or deleting the basic frequency blocks in units of blocks, wherein the frequency band is configured from a plurality of basic frequency blocks having at least a first basic frequency block and a second basic frequency block, in which case wireless communication is performed using the FDD technique for the first basic frequency block, and using the TDD mode or the half-duplex FDD mode for the second basic frequency block.
