The major objectives of the next generation wireless networks include: (1) achieving high data throughput in the fast varying wireless channel; (2) transmitting multi\u2010class data by service multiplexing; and (3) controlling the delay for delay sensitive service. To achieve these goals, in the context of wideband code division multiple access (WCDMA) system, we propose a cost\u2010function based rate adaptation mechanism by taking account of both physical layer channel impacts and higher layer performance parameters, such as buffer occupancy and service priority. We implement this cross\u2010layer rate mechanism by exploiting the transport format (TF) selection procedure in the medium access control (MAC) layer of the WCDMA system. Through the proposed cross\u2010layer cost function, the TF selection procedure can dynamically adapt suitable spreading factors every transmission time interval (TTI), usually 10\u201380\u2009ms. Through simulations in a flat Rayleigh fading channel, we show that the proposed cross\u2010layer cost\u2010function based rate adaptation mechanism can effectively improve throughput and reduce the buffer occupancy for multi\u2010class services for the WCDMA system at the cost of slightly higher power efficiency.
