Title:
SIGNAL AND CONTROL MECHANISM IN MIMOHARQ SCHEME FOR RADIO COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2004135304
Kind Code:
A
Abstract:

To provide a method for transferring signal information of a communication system using an MIMO antenna system.

A forward link signal channel is provided for transferring a large quantity of information relatively via the communication system to effectively utilize the MIMO antenna system, and contains swapping information or channel allocation information, such that the communication system can resend traffic information using arbitrary one of antenna elements of the MIMO system. Further, in order to deal with transfer of the relatively large quantity of information via the communication system, a form of backward link signal information is corrected using arbitrary one of or arbitrary combination of three mechanisms of multiplexing the backward link signal information in time division manner (1), modulating the backward link signal information in relatively high-order modulation (2) and providing an additional channel to the backward link information (3).
