Apparatus and method for determining data transmission rate in multi-hop relay system

摘要

Provided is an apparatus and method for determining a data transmission rate in consideration of the queue length of a Relay Station RS in a multi-hop relay system. A Base Station BS apparatus of the multi-hop relay system includes a receiver and a calculator. The receiver receives channel condition information and queue length information for a Mobile Station MS from an RS. The calculator of the BS apparatus determines a data transmission rate between the BS and the RS for data of the MS using the channel condition information and the queue length information.
