Patent ID: 7433460

Claim:
A method of controlling link transmission parameters of a communication flow in a network, comprising: compensating link quality indicators; selecting a modulation and coding scheme (MCS) using the compensated link quality indicators; caching one or more network parameters at the end of a first communication flow, the network parameters including the link quality indicators, the selected MCS, and at least one parameter based on an estimated additional downlink attenuation necessary for a mobile unit to achieve a given level of performance; and adjusting the network parameters for controlling at least one of a link quality and a transmit power of a next communication flow based on an uncertainty caused by an elapsed time between the first and next communication flows, wherein the adjusting includes: retrieving the cached MCS and the cached link quality indicators when the next communication flow is being established; and determining an initial MCS to be used for the next communication flow based on the retrieved MCS and the retrieved compensated link quality indicators, the compensating being based on the elapsed time.
