Abstract:
In a wireless communication system having a transmitter and at least one receiver coupled via a communication channel and operable to provide a communications path for at least one user application, a method for allocation of system resources among system transmitters comprising the steps of:determining a first and a second set of performance characteristic curves based on predetermined channel condition information in respect to said communications channel, wherein said first set of performance characteristic curves represents parameter values for an application layer of a layered protocol model for said communications channel and said second set of performance characteristic curves represents parameter values for a physical layer of said layered protocol model; determining a Quality of Service (QOS) requirement for said user application; determining a set of data pairs on said first set of performance characteristic curves that correspond to said QOS requirement; mapping said determined set of data pairs on said first set of performance characteristic curves to a corresponding set of data pairs on said second set of performance characteristic curves, each said mapped data pair on said second set of performance characteristic curves being functionally related to a transmission power level in said communications channel; from said mapped data pairs on said second set of performance characteristic curves, selecting a pair corresponding to a lower transmission power level in said communications channel.
