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 ba…
