Abstract
A method of controlling link transmission parameters of a communication flow in a network caches one or more network parameters at the end of a first communication flow for an elapsed time, and adjusts the network parameters for controlling link quality and transmit power of a next communication flow based on an uncertainty that is caused by caching for the elapsed time. The state of a communication channel during a previous communication flow (connection) is used to determine network parameters to use at a future communication flow. When a connection begins, and the network does not know the ideal settings to use, the network defines a specified, elapsed time duration over which the state of a previous connection no longer can be trusted, i.e., an uncertainty period. Network parameters are adjusted to account for uncertainty caused by the elapsed time.
