Abstract

A flexible NFRP procedure is proposed where the AP can adjust the granularity of the possible answers to a given question. The NFRP trigger frame includes a tone set configuration indication representative of a number of tone groups per RU tone set. The number of possible FEEDBACK_STATUS values consequently also varies, making it possible for the AP to poll the stations for more detailed feedback reports. A station determines which FEEDBACK_STATUS values are available, calculates its FEEDBACK_STATUS value and retrieves the corresponding subset of tone groups on which energy must be sent. Due to the multiples existing tone set configurations, the station also determines the tones forming the subset to be activated, based on the tone set configuration indication. The station can then properly send its feedback report response by activating (emitting energy on) the appropriate tunes and therefore the appropriate tone groups.
