Overview of ARQ and HARQ in beyond 3G systems
Antonio Maria Cipriano, Paul Gagneur, Guillaume Vivier, Serdar Sezginer · 2010
In this paper, we present a review of automatic repeat request (ARQ) and hybrid ARQ (HARQ) mechanisms implemented or proposed in beyond 3rdgeneration (B3G) wireless systems based on OFDMA. In particular, we will focus on part of the IEEE 802.16 standard family (IEEE 802.16-2005, IEEE 802.16m) and on 3GPP Long Term Evolution (LTE). In the second part of this overview, some performance curves show how HARQ can help in reducing performance degradation in mobility context.
