Link adaptation algorithm for improved wireless transmission of delay-sensitive packet data services
TL;DR: In this paper, a new link adaptation algorithm designed to improve the transmission of delay-sensitive services is presented, and the results demonstrate that significant improvements in terms of transmission delay, throughput and operation of link adaptation itself, can be obtained with the proposed scheme.

Abstract: Link adaptation is a radio resource management technique that selects a transport mode based on the experienced channel conditions. The optimum mode is commonly determined so as to maximise the throughput. Although, this approach is suitable for best-effort services, it is not tailored for real-time services. Presented is a new link adaptation algorithm designed to improve the transmission of delay-sensitive services. The results demonstrate that significant improvements in terms of transmission delay, throughput and operation of link adaptation itself, can be obtained with the proposed scheme.

Link adaptation and power control for streaming services in EGPRS wireless networks
TL;DR: The results reveal that by aiming at required error targets and thus reducing error variability, the error-based scheme for link adaptation and power control are helpful in improving quality and capacity for streaming applications.
