Patent ID: 7751777

Claim:
A method for transmitting data in a communication network, the communication network comprising a first base station capable of transmitting data to a first destination subscriber station (DSS), and a second base station capable of transmitting data to a second DSS, wherein a co-channel interference is present at the second DSS during a transmission of the data from the first base station to the first DSS through a direct route, the method at the first base station comprising: selecting a relay station from a plurality of relay stations corresponding to the first base station for transmitting the data via a relay route, wherein the relay route comprises a route from the first base station to the relay station and further from the relay station to the first DSS, and wherein a height of the relay station is lower than a height of the first base station; and transmitting the data through the relay route when a throughput of the relay route is greater than a throughput of the direct route by a predetermined threshold.
