Abstract
This paper models and analyzes the performance of TCP (Transmission Control Protocol) under joint rate and power adaptation with constrained BER requirements for downlink data transmission in a multi-cell VSF (Variable Spreading Factor) WCDMA system. The performance of TCP in a wide-area internet1 environment is evaluated by using computer simulations considering user mobility, short-term fading (i.e., multipath fading) and long-term fading (i.e., shadowing). The motivation is to explore the inter-layer protocol interactions and to identify suitable transport and radio link layer mechanisms to improve wireless TCP performance in a cellular WCDMA environment.
