Abstract

User-cooperative transmission exploits spatial diversity created by antenna sharing in a wireless network. The paper investigates the performance of narrowband, slowly fading and delay-limited cooperation systems where perfect channel state information (CSI) is available at cooperative transmitters. Power control algorithms which attempt to minimize the outage probability under short-term and long-term power constraints are developed. We show that significant improvement of outage probability is achieved through exploiting the CSI of forward channels.
