1. An apparatus for wireless communications at a first user equipment (UE), comprising:
a processor; and
a memory, coupled with the processor, the memory storing instructions executable by the processor to cause the apparatus to:
transmit a first set of reference signals via a primary sidelink carrier of a sidelink carrier aggregation configuration and a second set of reference signals via one or more secondary sidelink carriers of the sidelink carrier aggregation configuration;
receive, based at least in part on the first set of reference signals and the second set of reference signals, a measurement message indicating measurements for a set of beams corresponding to a secondary sidelink carrier of the sidelink carrier aggregation configuration based at least in part on a beam failure instance for the primary sidelink carrier; and
transmit, via Layer 1 signaling or Layer 2 signaling, a control message indicating to switch the primary sidelink carrier to the set of beams based at least in part on the measurements for the set of beams and the beam failure instance for the primary sidelink carrier.
