Dynamic carrier allocation in a PRMA cellular network

This paper proposes a technique to allow the dynamic channel allocation in a PRMA personal communication network (PCN) in urban and indoor environments, where cells have small extension and may present large and sudden variations in the number of users. The proposed technique is also suitable for coping with variable-band services. The paper proposes original solutions to the following crucial problems: (i) the determination of a short-term parameter for assessing the link quality of a PRMA carrier in a microcellular environment; (ii) the determination of a procedure the base station can follow in order to perform a real-time estimation of the above-mentioned short-term parameter; (iii) the interworking between the DCA mechanism and the PRMA technique. Simulation results show a remarkable improvement in system performance, due to both the DCA and PRMA techniques.
