Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radar device may transmit a combined frequency modulated continuous wave (FMCW) radar signal, wherein the combined FMCW radar signal comprises: a first FMCW radar chirp generated based at least in part on a first set of transmission parameter values; and a second FMCW radar chirp generated based at least in part on a second set of transmission parameter values, wherein a transmission parameter value of the second set of transmission parameter values is different than a corresponding transmission parameter value of the first set of transmission parameter values. The radar device may detect a radar target based at least in part on a received signal corresponding to the combined FMCW radar signal and perform an action based at least in part on detecting the radar target. Numerous other aspects are provided.

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.
