Radio Resource Allocation with Resource Metric Estimation for Multimedia CDMA Systems

In this paper, the radio resource allocation with resource metric estimation (RME) technique is presented and discussed, which is applicable to wireless multimedia CDMA systems such as W-CDMA and single-code or multi-code multi-carrier ((MC)2)-CDMA system. Based on call admission criterion, the admissible residual resource region in which QoS and acceptable link quality for NRTT data users can be guaranteed are demonstrated. It is shown that the resource allocation with the predictive RME can deliver exact status of residual ADR and admissible capacity region, which in turn can decide appropriate allowable rates for each data users. Thus, the full utilisation of left resource, i.e. the residual capacity, can be achieved in a dynamic and predictive manner.
