Abstract:
1. A cellular wireless network using orthogonal frequency division multiplexing (OFDM) comprising a plurality of base stations and a plurality of relay stations, the network being arranged to allocate radio resources within the network in accordance with a frame structure comprising first selected frequencies corresponding to a first sub-set of OFDM subcarriers and second selected frequencies corresponding to a second, different sub-set of OFDM subcarriers, the frame structure further comprising a first timeslot for the transmission of control data and a second timeslot for the transmission of payload data; wherein the base stations are configured so as to transmit control data within the first timeslot at the first selected frequencies, and to transmit payload data within the second timeslot at the second selected frequencies; and wherein the relay stations are configured so as to transmit control data within the first timeslot at the second selected frequencies, and to transmit payload data within the second timeslot at the first selected frequencies.
