1. A User Equipment, UE, for enabling Global Navigation Satellite System, GNSS, measurements, the UE and a network node being comprised in a New Radio, NR, communications network, and the NR communications network comprising a Non-Terrestrial Network, NTN, component, the UE being configured to:
perform a GNSS measurement according to a rule and using a GNSS receiver comprised in the UE, wherein at least one of a UE position and an absolute time is an output of the GNSS measurement or is derivable from the GNSS measurement, the rule being that the GNSS measurement is performed with a periodicity associated with at least one of:
a Discontinuous Reception, DRX, cycle;
an enhanced Discontinuous Reception, eDRX, cycle; and/or
a Tracking Area Update, TAU, timer; and
a Radio Access Network based Notification Area Update, RNAU, timer,
the rule being that the GNSS measurement is performed with a periodicity when the UE is in idle mode.
