Abstract :
The design and development of suitable RRM strategies is a key issue for the future efficient use of 3G systems available spectrum. In the case of the downlink direction, the allocation of radio resources is more difficult than in the uplink case because it is influenced by the instantaneous location of the users in the cell. Also, the base station transmitted power must be shared by all users whereas in the uplink case each user has its own power amplifier. This paper studies several down link-specific issues in order to provide some guidelines for a proper design of admission control, congestion control and downlink dynamic resource allocation.
