Abstract

This paper characterizes the downlink transmission power for WCDMA networks in multiservice environments for both urban and suburban macro cells. To calculate the required transmission power for the user in the cell, various modeling approaches are used to investigate the orthogonality, the path loss, and the inter-cell interference ratio of the user. The variation and scattering pattern of the required transmission power for each service connection are observed as a function of distance between the base station (BS) and the mobile station (MS). The phenomena and their explanations presented in the paper concerning the WCDMA downlink power issues are important for the power control and admission control of the system.
