    摘要： Disclosed is a system and method for transmitting data from a first base station to a first destination subscriber station (DSS). The first base station is capable of transmitting data directly to the first DSS through a direct route. Co-channel interference is present at neighboring cells during the transmission of the data through the direct route. The method includes selecting a relay station from a plurality of relay stations for transmitting data to the first DSS via a relay route. The relay route includes a route from the first base station to the relay station and further from the relay station to the first DSS. A height of the relay station is lower than a height of the first base station. Further, the method includes 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.

    摘要： Methods and apparatuses for reducing an amount of bandwidth required for feedback to a transmitter station in a closed-loop multiple-input multiple-output (MIMO) system are described herein. The methods may include initially measuring at a receiver station channel qualities associated with receiving signals from a transmitter station for a first and a second spatial channel, the transmitter and receiver stations employing a closed-loop MIMO system. The receiver station may then determine a first and a second channel quality indicator (CQI) based on the measured channel qualities and may then transmit to the transmitter station the first and the second CQI to directly and indirectly identify a first and a second modulation coding scheme (MCS) entry among a plurality of ordered MCS entries, respectively. The second MCS entry being one of a selected subset of lower ordered MCS entries relative to the first MCS entry. The transmitter station may selectively use the first and the second identified MCS to transmit signals to the receiver station over the first and the second spatial channel, respectively.
