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.
