Summary: 
This paper defines the maximum available radio resource of a WCDMA downlink in a multiservice context under different wireless conditions. The derived closed-form expression for the maximum available resource, denoted by Rmax, is determined by four important service-independent system parameters: the maximum downlink transmission power, the average propagation loss, the average orthogonality factor, and the average other-to-own-cell interference ratio of the cell. From the Rmax some important radio characteristics of a WCDMA downlink are observed. The application of the Rmax to the link-sharing dimensioning process of WCDMA networks is presented in the paper. Simulation studies are provided to show the accuracy of the analytical model under various urban macro cell conditions.
