Abstract:
Various aspects relate to adjusting communication timing in response to a switch from one feeder link to another feeder link in a non-terrestrial network. For example, when a satellite moves out of the coverage area of a first ground network entity (or if the first ground network entity is turned off), the satellite switches to a second ground network entity. The resulting switch from a first feeder link for the first ground network entity to a second feeder link for the second ground network entity may cause a timing glitch that adversely affects the UEs under the coverage of the satellite. The disclosure relates in some aspects to sending an indication of the switch and/or a common timing adjust command to all of the UEs affected by the feeder link switch.
