11.10 Filtered UE power headroom (FDD)

25.3213GPPMedium Access Control (MAC) protocol specificationTS

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

If the parameter "Filter coefficient" is received the UE shall, depending on the measurement quantity (see Table 11.10.1), apply filtering of the measurements for UE power headroom according to the formula below. This filtering shall be performed by the UE before UE event evaluation.

The filtering shall be performed according to the following formula.

The variables in the formula are defined as follows:

F_nis the updated filtered measurement result

F_n-1 is the old filtered measurement result

M_n is the latest received measurement result from physical layer measurements, the unit used for M_n is the same unit as the reported unit in the unit used in the event evaluation.

a = 1/2^(k/2), where k is the parameter received in the parameter "Filter coefficient".

In order to initialise the averaging filter, F₀ is set to M₁ when the first measurement result from the physical layer measurement is received.

The physical layer measurement results are sampled once every measurement period. The measurement period and the accuracy for a certain measurement is defined in [12].

Table 11.10-1 lists for all measurement quantities and reporting quantities if L2-filtering is applicable or not and used L2-filtering type for each measurement quantity.
