Providing IP services with QoS support in heterogeneous networks involving wired and wireless sections has been identified as a challenging task. The goal of this paper is to show how link level mechanisms can be enhanced by transport layer information in order to meet transport layer reliability and delay requirements within wireless scenarios. Error control mechanisms in Layer 2, Layer 4, and a combination of them are compared. The benefit for TCP-based and RTP/UDP-based applications of using a CDMA based MAC protocol that employs "Simultaneous MAC Packet Transmission" (SMPT) are demonstrated.
