- Joint Uplink and Downlink Capacity Considerations in Admission Control in Multiservice CDMA/HSDPA Systems
- TCP-based data flows generate packets and ACKs in two directions, be it in the wireline or wireless networks. In the latter case, packets are typically found in the downlink whereas ACKs are in the uplink. Those two links are asymmetric in the case of CDMA-based High Data Rate HDR/High-Speed Downlink...

- Enhancing TCP Over HSDPA by Cross-Layer Signalling
- A comprehensive performance evaluation of a cross-layer solution to increase users' downlink data rates over HSDPA is provided. The solution consists of a proxy entity between a server and the Radio Network Controller, and cross-layer signaling from the base station to the proxy. The performance of the solution is evaluated...
