We introduce a new approach, based on social welfare maximization, for determining the coverage of a single cell in a WCDMA system. The approach takes into account resource usage in the uplink direction, and captures the tradeoff between having a large cell with many users versus having a smaller cell with fewer users, which however are able to transmit at a higher rate. Our numerical investigations demonstrate how cell coverage determined using the above approach is affected by various system parameters, such as the path propagation characteristics, the mobile power limit, and the distribution of mobile hosts within a cell. Keywords: resource usage, utility, dynamic cell coverage, cell breathing, network planning
