Title:
MOBILE COMMUNICATION SYSTEM, BASE STATION DEVICE, AND MOBILE STATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/013034
Kind Code:
A1
Abstract:
It is possible to provide a mobile communication system, a base station device,
and a mobile station device enabling data transmission of high reliability by
using the MIMO signal processing technique in the OFDM method with data communication
service such as MBMS in which a plurality of base station devices transmit the
same information to a plurality of mobile station devices. The plurality of
base station devices (2) which have received the same information sequence via
a base station control device (1) from a server map the information sequence to
a modulation symbol, divide the modulation symbol into blocks, assign frequency
blocks different from the other base station devices(2) to each of the blocks,
and transmit them to the mobile station devices(10). Upon reception of the signal,
the mobile station devices(10) demodulate it by a MIMO reception signal processing
unit (13) and output it.
