Ranging Request Measurement IE (RRM IE)
Reply Time Request (RTR) field denotes whether the reply time of ERDEV sending response to the message with RRM IE is requested: if RTR value is one, the reply time is requested, otherwise it is not.
Round-trip Measurement Request (RMR) field indicates whether the round-trip measurement of ERDEV upon receiving message with RRM IE is requested: if RMR value is one, the round-trip measurement is requested, otherwise it is not.
Following bit-fields for ToF request (TOFR), AoA Azimuth Request (AAR), and AoA Elevation Request (AER) denote whether time-of-flight (ToF), azimuth AoA, elevation AoA are requested or not: if a bit-field of request has value one, the corresponding information is requested, otherwise it is not.
