Abstract

A method for signalling in a MIMO system. The system comprises a base station (BS), and at least one relay station (RS), operating in half duplex realized using Time Division Duplex. The BS and the RS distribute channels to at least one mobile station (MS), The method is particularly characterized in the steps where:-the BS selects at least one RS which is served during a first time slot (TS1), and selects at least one MS which is served during a second time slot (TS2),—the BS creates channels during T1 to said RS,—the BS and said RS create channels during T2 to said MS.
