Detailed Description

PER RA works only using the statistics of received ACKs as a reply to the used MCS. Hence, it slowly increases the rate by selecting high-rate MCSs, until the PER exceeds a given value. Then, it stays at the next lower MCS until the percieved PER changes again.

const [virtual]

This method returns the currently selected phyMode of the specific rate adaptation strategy, given the number of transmissions for the frame. This method is const and thus cannot change the internal state of the rate adaptation strategy. Hence, multiple calls to the method at the same simulation time and number of transmissions (e.g. to calculate transmit durations) return ALWAYS the same phyMode.
