Abstract

In this paper, we propose an adaptive radio interface scheme for systems that employ multiple antennas. This is in contrast to the adaptive interface of single-antenna systems like in current packet data cellular systems. We propose groups of transmission parameters called modulation, coding and antenna schemes (MCAS) that are chosen according to the current conditions of the wireless channel, in order to maximize the performance in terms of good put, while maintaining a certain level of reliability.
