1. A method for wireless communication at user equipment (UE) in a non-terrestrial network, comprising:
receiving a radio resource control (RRC) message that indicates that the UE is to release from an active mode into an idle mode on a second cell before selecting a first cell and to select the first cell associated with a first satellite for the wireless communication in the non-terrestrial network based on a group identification identifying one or more satellite-cell groups for initiating selection by the UE;
selecting the first cell associated with the first satellite for wireless communication in the non-terrestrial network;
determining whether to use either one or more standard parameters or one or more satellite-cell specific parameters for accessing the first cell, wherein the one or more standard parameters are based on one or more standard characteristics common to a plurality of satellites including the first satellite, and wherein the one or more satellite-cell specific parameters are used if it is determined that a change to at least one standard characteristic of the one or more standard characteristics of the first satellite has occurred; and
communicating with a base station via the first satellite.
