Abstract
In this paper we evaluate the potentials of the Frame Descriptor Table concept. Newly developed mobile radio interfaces beyond 3rd generation (B3G) present a new set of challenges in regard to medium access control protocols. Beside the requirement of supporting high Quality of Service B3G systems will need to achieve high spectral efficiency. Hence, new concepts have to be developed in order to enhance the efficiency of resource reservation. This work evaluates the performance of the promising concept of Frame Descriptor Tables (FDT) introduced in [1] regarding its impact on delay and throughput. Assuming a frame based reservation scheme, the concept helps to reduce signaling overhead by eliminating redundant description of frame layout across frames. This is done by caching the descriptions of frame layouts in mobile stations and referencing a certain description by transmitting an associated ID. This merges the concepts of frame based resource reservation and the reservation of TDMA channels in order to take advantage of the merits of both concepts. The simulations done in the course of this work show the resulting positive effects on signaling overhead. The results presented show a reduction of overhead and the feasibility and usefulness of establishing TDMA channels using a MAC protocol employing a frame based reservation.
