Abstract
A multi-hop wireless communication network is disclosed, which includes a fixed communication unit, at least one mobile communication unit, and a relay communication unit. The relay communication unit is operable to relay a plurality of signals bi-directionally between the fixed communication unit and the at least one mobile communication unit, by receiving a first signal on at least one of a dedicated sub-carrier and a dynamic sub-carrier in a first downlink channel segment from the fixed communication unit, and transmitting the received first signal to the at least one mobile communication unit on a dynamic sub-carrier in a second downlink channel segment. Also, the relay communication unit is operable to receive a second signal on a dynamic sub-carrier in a first uplink channel segment from the at least one mobile communication unit, and transmit the received second signal to the fixed communication unit on at least one of a dedicated sub-carrier and a dynamic sub-carrier in a second uplink channel segment. Also, the fixed communication unit can allocate bandwidth dynamically or in a fixed amount in the first downlink channel segment, the relay communication unit can allocate bandwidth dynamically in the second downlink channel segment based on at least one Quality of Service value received from the at least one mobile communication unit, the relay communication unit can allocate bandwidth dynamically for the at least one mobile communication unit in the first uplink channel segment, and the fixed communication unit can allocate bandwidth dynamically or in a fixed amount for the relay communication unit in the second uplink channel segment.
