MARGin?
3 RP 12 Value - the maximum ripple between the upper side of Range 1 and lower side of Range 2
4 RP 21 Value - the maximum ripple between the upper side of Range 2 and lower side of Range 1
5 Min Ec(f)1 - the minimum EC(f) in Range 1
6 Max Ec(f)1 - the maximum EC(f) in Range 1
7 Min Ec(f)2 - the minimum EC(f) in Range 2
8 Max Ec(f)2 - the maximum EC(f) in Range 2
Index Result Parameter
0 Results Length - The total length of the results (includes the length field itself),
currently fixed to 53
1 Average Power of Active RBs - the average abosulted power of allocated RBs in
dBm
2 Number of RBs - the number of RBs in current configuration
3 - 52 Power Per RB - the abosulted power (dBm) per RB. Only the first
Number_OF_RBs values are valid.
Index Result Parameter
0 Results Length – The total length of the results (includes the length field itself), currently fixed to 54
1 Minimal Inband Margin - Inband margin is the difference between the inband emission limit mask and
actual measured power per non-allocated RB. The margin = (Limit – Power ) in dB. A negative margin
indicates that the power exceeds the limit.
2 Minimal Inband Margin Index – the RB index of minimal margin results (ZERO based)
3 Number of RBs - the number of RBs in current configuration
4 - 53 Inband Margin per RB - The Margin result of each RB. (only the first Num_of_RB values are valid). If
the RB is active (allocated), the inband margin result will be set to NAN.
