Abstract :
A distributed dynamic resource allocation (DDRA) strategy is proposed for a hierarchical cellular structure (HCS), where resources are shared not only between cells of the same hierarchy but between layers. This strategy is evaluated using the hybrid TDMA/CDMA proposal made in the Frames Project Mode 1 (FM1) as a case study. Users are classified according to their speed as slow moving users and fast moving users and are attended to by the most suitable layer of the HCS according to their speeds. Two types of real time circuit switched services are considered in the evaluation: speech and data at different rates
