Abstract
A method of operating a wireless communications system comprising at least a base station, a first relay station, a second relay station and one or more subscriber stations; using at least a first wireless protocol with the first relay station, and using at least a second wireless protocol with the second relay station. Operation of the method comprises using a subframe which comprises: a first-protocol access period; a firstprotocol relay period; a second-protocol access period; and a second-protocol relay period. The subframe further comprises an idle period to avoid communications using the first wireless protocol interfering with communications using the second wireless protocol and the overall frame structure is arranged to position the idle period for the first relay station between the first-protocol access period and the first-protocol relay period, to accommodate switching of the first relay station between transmit and receive modes.
