1. A method for estimating latency in a packet based wireless network for communication between two network nodes, wherein the method comprises:
a. measuring at least one of the following metrics while in idle mode from a serving cell and/or non-serving cell and/or beams:
i. total received power at a user equipment,
ii. pilot signals power,
iii. reference signals power,
iv. interference power,
v. noise power,
vi. signal to noise ratio,
vii. signal to interference-plus-noise ratio,
viii. number of re-transmissions,
ix. cell re-selection,
x. cell configuration;
b. estimating latency by using multivariable, non-linear or linear function prediction, machine learning based prediction or mathematical or logical predictions based on the at least one metric,
c. wherein the at least one measured metric is filtered and/or, when several metrics are measured, aggregated during a measurement window to create new higher level at least one metric resulting in improved latency estimation accuracy, where the measurement window comprises either one or several combinations of:
a. measurements from prior time,
b. measurements during the transmission interval,
c. measurements within a spatial area.
