Abstract:

In this paper we consider the downlink of an Orthogonal Frequency Division Multiplexing (OFDM) based cell that accommodates Poisson arriving calls generated from different service-classes and having different traffic description parameters. The system is modelled as a multirate loss model. To determine Call Blocking Probabilities (CBP) and resource utilization in this system, we propose a recursive formula which reduces substantially the complexity of the calculations. This fact makes the formula attractive for network planning and dimensioning procedures. Besides, as we show in this paper, the proposed formula can be used as the springboard for the analysis of more complicated subcarrier sharing policies, such as the Multiple Fractional Channel Reservation (MFCR) policy. The MFCR policy can be used for the reservation of subcarriers in order to reduce CBP and therefore favor calls of high subcarrier requirements.
