Abstract

In a UMTS (Universal Mobile Telecommunications System) wherein multiple base stations are able to communicate simultaneously with the same mobile station, with forward direction power control where the mobile station sends a transmit power control command to all base stations serving it, each base station is assigned an individual target value (TV1) from which the transmitted power level should not deviate on a long term average, thereby achieving high macrodiversity gain even under poor receiving conditions.
