fixeria gerrit-no-reply at lists.osmocom.orgHello Jenkins Builder, laforge, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-bts/+/20730 to look at the new patch set (#3). Change subject: power_control: tolerate small deviations from 'rx-target' ...................................................................... power_control: tolerate small deviations from 'rx-target' Recently we've introduced EWMA based uplink power filtering, that should reduce Uplink power oscillations. However, the power loop is still quite sensitive to small deviations from the target power level: even such an insignificant deviation like 2-5 dBm triggers the loop to increase or decrease the MS power level. Even if the EWMA based filtering is enabled with 80% smoothing (alpha = 0.2). This change introduces a new configuration parameter - 'hysteresis': uplink-power-target <-110-0> hysteresis <1-25> that together with the 'uplink-power-target' defines a range: [target - hysteresis .. target + hysteresis] in which the MS power loop would not trigger any power changes. This feature is now *enabled* by default, so given that: - default 'uplink-power-target' is -75 dBm, and - default 'hysteresis' is 3 dBm, the default target Uplink power range is: -78 dBm ... -72 dBm.
