This paper provides the framework for the design of downlink admission control algorithms in the FDD mode of UMTS. Such algorithms are responsible of accepting or refusing requests of new connections depending on the resource availability in the downlink direction, which is measured in terms of the power and the amount of OVSF codes required In all the existing connections. So a specific algorithm that account for both power and code availability is presented and it is analyzed for different situations, revealing the crucial parameters that should be appropriately set in order to ensure the QoS expected by all the admitted connections.
