Methods, systems, and devices for wireless communications are described. A user equipment (UE) may 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. The UE may receive, based on the 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 on a beam failure instance for the primary sidelink carrier. The UE may 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 on the measurements for the set of beams and the beam failure instance for the primary sidelink carrier.

Techniques for primary sidelink carrier updating in sidelink carrier aggregation

A first UE may establish a sidelink connection with at least one second UE via a first PCC. The first PCC and a first set of SCCs may be associated with a first transmission of the first UE. The sidelink connection with the at least one second UE may be associated with carrier aggregation. The first UE may detect, and transmit a first indication, that at least one of (i) the sidelink connection is associated with an RLF value that is within an RLF threshold of an RLF limit, or (ii) the first set of SCCs is capable of maintaining the sidelink connection. The first UE may receive, based on the first indication, a second indication of a switch of the sidelink connection from the first PCC to a first SCC of the first set of SCCs.
