In \\cite{A.Sampath 95}, the model of transmit power minimization problem in CDMA systems uplink is presented. In this paper, we first review previous work, then investigate the transmit power minimization in CDMA systems downlink. The sufficient and necessary conditions for the existence of the \\emph{feasible solutions} are analyzed. We also provide the optimal solutions to uplink and downlink models. The optimal solutions can be used as a reference for power control and radio resource allocation in multimedia CDMA systems.<br \/>\n<span class=\"paper_subtitle\">KEYWORDS<\/span><br \/>\nMultimedia CDMA, downlink, transmit power minimization.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><a href=\"http:\/\/network.ee.tsinghua.edu.cn\/papers\/xiang_capacity_pimrc2002.pdf\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-117\" title=\"pdf\" src=\"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/wp-content\/uploads\/2010\/08\/pdf.gif\" alt=\"\" width=\"95\" height=\"50\" \/><\/a>Xiang Duan, Zhisheng Niu, Junli Zheng, <span class=\"papertitle\">Donwlink Transmit Power Minimization in Power-Controlled Multimedia CDMA Systems<\/span>, <span class=\"papersource\">Proc. 13th IEEE Int.
