A forwarding concept for HiperLAN/2

A new approach to extend the communication range of standard HiperLAN/2 (H/ 2) cells is presented. The basic idea is to use a relay in the time domain that supports terminals outside the range of a H/2 access point. The concep t presented employs a novel MAC sub-frame structure generated by a new H/2 element called Forward Mobile Terminal (FMT) that serves out-of-range termi nals, We present an analysis of the impact of FMTs on the achieved Quality of Service (QoS) for the H/2 system. Further, the possible service area ext ension is analysed. (C) 2001 Elsevier Science B.V. All rights reserved.
