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.

Key Words: WCDMA, downlink, radio resource, link sharing
