Radio resource metric estimation for wireless CDMA communication systems maximising radio resource utilisation

In this paper, we propose a predictive resource metric region (RMR) based resource metric estimation method, which utilizes a resource metric mapping function (RMMF), both of which permit efficient inter-working between the physical layer and higher layers. The RMR can provide the acceptable resource region where QoS and acceptable link quality can be guaranteed with an achievable resource margin to be utilized in terms of capacity margin, the degree of confidence (DCL) of user, second-order statistics of Eb/Io. With predicted capacity margin and variance, DCL can deliver decision parameters with which an adaptive QoS based admission control can perform well taking capacity and resource availability into account in a dynamic and predictive manner.
