Automatic repeat request (ARQ) mechanism in HIPERLAN/2

Abstract

A WLAN standard, called HIPERLAN/2 (H/2), is currently defined in the ETSI/BRAN project. The standard can provide wireless access to several fixed networks with high data rate (up to 54 Mbps) in 5 GHz frequency range. To guarantee robustness in various types of radio channels a selective repeat ARQ with partial bitmap SRPB has been adopted as an error control mode. The SRPB ARQ mechanism was selected due to efficient retransmissions and low overhead of ARQ acknowledgements. The dynamic assignment ARQ acknowledgement opportunities integrated in SRPB can reduce the delay of acknowledgements and enhance the throughput. In this paper we describe the SRPB ARQ mechanism in H/2 and show the simulated performance.
