Abstract:
1. A method comprising: transmitting packets to a receiver using an MCS (modulation and coding scheme); receiving NACKs (negative acknowledgement) in respect of packets transmitted to the receiver; determining an updated MCS (modulation and encoding scheme) used to transmit subsequent packets to the receiver as a function of the received NACKs, wherein adapting an MCS (modulation and encoding scheme) used to transmit the sequence of packets as a function of the received negative acknowledgements comprises: counting a number of NACKs received over a time period, wherein updating an MCS (modulation and encoding scheme) used to transmit the sequence of packets as a function of the received negative acknowledgements further comprises: moving to a less aggressive MCS if the number of NACKs received over the time period exceeds a first threshold; moving to a more aggressive MCS if the number of NACKs received over the time period is less than a second threshold.
