Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source base station, configuration information for a handover, wherein the configuration information indicates, for a target non-terrestrial cell, timing and synchronization parameters including a scheduling timing offset, a round trip time between a reference point and a target base station associated with the target non-terrestrial cell, satellite ephemeris information, an ephemeris validity duration associated with the satellite ephemeris information, common timing advance parameters, and a common timing advance validity duration associated with the common timing advance parameters. The UE may perform the handover with the target base station associated with the target non-terrestrial cell based at least in part on the timing and synchronization parameters for the target non-terrestrial cell. Numerous other aspects are described.
