Document Type and Number:
WIPO Patent Application WO/2006/075386
Kind Code:
A1
Abstract:
An orthogonal frequency division communication system, which ensures similar advantages to those of TDD (Time Division Duplex) and which allows the assignment ratio between the uplink and the downlink to be changed in a more flexible manner, comprises a plurality of mobile stations and a base station that are connected to each other via the uplink and downlink. A plurality of mutually orthogonal frequencies are assigned, on the axes of frequency and time, to the uplink and downlink and to the plurality of mobile stations.
