Abstract
Overwhelming majority of the next generation wireless cellular networks are based on CDMA (Code Division Multiple Access) technologies, with various flavors such as CDMA2000, WCDMA and their variations. Compared to the existing cellular networks which are designed for voice-only applications, the upcoming networks will be capable of providing high throughput and QoS dependent applications such as gaming, real-time streaming media, video conferencing etc., without significant improvements in the overall network capacity. Therefore for satisfactory end-user experiences, efficient use of the scarce network resources is vital. An efficient such algorithm has to depend on the estimates of information gathered from the network, such as the channel gains, received power levels, intercell/intracell interference etc. In such a scheme there are inherent sources for inaccuracies for the estimated values, such as the measurement errors, the delay in the estimates and the inaccuracies in models used for estimation. Implementing a resource allocation scheme which is robust 12to such measurement errors is important. In this paper, we study an optimum resource allocation scheme in a CDMA based cellular network, which is capable of allocating network resources to end-users of multimedia type applications, with QoS guarantees which are robust to inaccuracies in the estimated values, provided that those estimates can be bounded within a certain neighborhood of the real values.
