Feedback generation for link adaptation

A system, comprising:

• a processing circuit;
• and
• memory, operatively connected to the processing circuit and storing instructions that, when executed by the processing circuit, cause the system to perform a method, the method comprising:
• receiving a first transmission from a transmitter;
• calculating a first estimated packet error rate, for a first modulation and coding scheme and a first number of spatial streams, the first modulation and coding scheme having a first modulation and coding scheme index;
• determining that the first estimated packet error rate is less than a threshold;
• and
• in response to determining that the first estimated packet error rate is less than the threshold, calculating a second estimated packet error rate, for a second modulation and coding scheme.
