heal.abstract	In this paper the problem of resource allocation for the downlink in code division multiple access wireless networks supporting multimedia services is addressed. A utility based power and rate allocation algorithm which aims at optimizing system's performance while satisfying multiple services' diverse Quality of Service (QoS) requirements is introduced and analyzed. For the efficient support of real-time users our proposed methodology takes into account their short-term throughput QoS constraints satisfaction, which is achieved by dynamically adapting their utility functions with respect to their corresponding short-term service performance information. Through modelling and simulation it is demonstrated that significant performance improvements are achieved in terms of the short-term throughput requirement satisfaction even for large number of real-time users, without any considerable loss in the total system's throughput. © 2007 IEEE.	en
