<p>A method to increase spectral efficiency in a communication system is described herein. The communication system includes at least one mobile station and is capable of transmitting messages encoded according to a plurality of available modulation coding schemes ("MCSs"). Each available MCS includes a modulation scheme and an effective coding rate. The MCSs are indexed according to increasing complexity. A signal-to-interference ratio ("SINR") is determined which is sufficient to satisfy a predetermined frame error rate ("FER"). A first MCS and a corresponding amount of transmissions needed to satisfy the predetermined FER at the SINR using the first MCS are determined. The first MCS has a higher effective coding rate than a second MCS. The second MCS sufficiently satisfies the predetermined FER at the SINR in a single transmission. A message encoded according to the first MCS is transmitted through the communication system using hybrid automatic repeat request ("HARQ").</p> |
