Abstract

According to some embodiments, a method performed by a wireless device comprises receiving a measurement configuration to measure reference signals from one or more satellite cells of a plurality of satellite cells. The measurement configuration includes one or more parameters that indicate how the measurement configuration is to be updated over time. The method further comprises: measuring a reference signal on one or more selected satellite cells using a first measurement configuration based on the received measurement configuration; dynamically adapting the measurement configuration based on the received parameters that indicate how measurement configuration is to be updated resulting in a second measurement configuration; and measuring a reference signal on one or more selected satellite cells using the second measurement configuration.

Dependent claims

A method performed by a wireless device, the method comprising:

receiving a measurement configuration to measure reference signals from one or more satellite cells of a plurality of satellite cells, wherein the measurement configuration includes one or more parameters that indicate how the measurement configuration is to be updated over time;
measuring a reference signal on one or more selected satellite cells using a first measurement configuration based on the received measurement configuration;
dynamically adapting the measurement configuration based on the received parameters that indicate how measurement configuration is to be updated resulting in a second measurement configuration;
measuring a reference signal on one or more selected satellite cells using the second measurement configuration;
and
wherein the one or more parameters that indicate how the measurement configuration is to be updated over time comprise a measurement window or measurement gap of a configured constant duration that is repeatedly time shifted with a constant time shift wherein each resulting measurement window or measurement gap has an associated validity duration, after which a next time shift is applied.
