초록 ▼

The embodiments balance wireless communication bandwidth capacity in a channel one or more cascading wireless communication links in a wireless communication cell, and manage the wireless communication bandwidth capacity in the channel across two or more virtual cells within the wireless communicati

대표청구항 ▼

What is claimed is: 1. A method, comprising:managing wireless communication bandwidth capacity in a single channel of one or more cascading wireless communication links in a wireless communication cell, a cascading wireless communication link being a wireless communication link among a first node and one or more relay second nodes to one or more third nodes, and a wireless communication link between the first node and the relay second node being a relay link and a wireless communication link between the relay second node and a third node being an access link; andmanaging the wireless communication bandwidth capacity in the single channel across two or more virtual cells within the wireless communication cell, each virtual cell being a service area of a relay second node and one or more third nodes,wherein the managing of the wireless communication bandwidth capacity includes adjusting the bandwidth in a cascading wireless communication link among a relay link and/or an access link of the cascading wireless communication link and across two or more virtual cells, based upon a transmission congestion level according to average transmission queue lengths over a time interval at any combination of the nodes in the cascading wireless communication link and/or in the virtual cells.
