Abstract:
1. A method of operating a wireless access node to provide wireless backhaul to a plurality of relay nodes associated with the wireless access node, the method comprising: transmitting a first beamformed backhaul link to a first relay node and a second beamformed backhaul link to a second relay node by at least allocating a first quantity of resource blocks of a carrier frequency to the first beamformed backhaul link and a second quantity of the resource blocks of the carrier frequency to the second beamformed backhaul link; monitoring traffic load information for the relay nodes while providing the wireless backhaul; and when the traffic load information exceeds a load threshold for the first relay node, then increasing a bandwidth of the first beamformed backhaul link for the first relay node by at least allocating a different amount of the resource blocks to the first beamformed backhaul link.
