Abstract

Link Adaptation is an adaptive radio resource management technique that selects a transport mode from a set of predefined modes of varying robustness, depending on the experienced channel quality conditions and dynamics. Previous work has shown the need to adapt the configuration of Link Adaptation to certain operating conditions affecting the channel quality dynamics. In particular, it was shown that the system load can considerably influence the performance and configuration of Link Adaptation techniques. The user mobile speed is another key factor influencing the channel quality dynamics. As a result, the aim of this paper is to investigate whether the user mobile speed should also be taken into account when configuring and designing the operation of Link Adaptation techniques.
