1. A user equipment (UE) for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
receive a signal indicating a first satellite group identifier (ID) of a first satellite group;
compare the first satellite group ID with a second satellite group ID of a second satellite group in a second satellite group ID set which is stored in a user equipment (UE), wherein the first satellite group ID is associated with first group ephemeris data and each satellite group ID of the second satellite group ID is associated with second group ephemeris data; and
determine an arrival time of a neighboring satellite in the second satellite group based at least in part on satellite level parameters of at least one satellite of the second satellite group, and difference values of satellite level parameters of other neighboring satellites in the second satellite group compared to the at least one satellite of the second satellite group.
