The disclosure relates to methods, devices, and systems for wireless communications. A wireless communications system may support unicast and broadcast communications for different radio access technologies (RATs). To support the coexistence of different RATs, a user equipment (UE) may report, to a base station, a UE capability message containing a band combination including one or more bands for a first RAT (for example, New Radio (NR)) and one or more bands for a second RAT (for example, Long Term Evolution (LTE)) and an indication of a baseband budget for the second RAT for the band combination. In some implementations, the UE may transmit a broadcast interest indicator to the base station requesting a broadcast service. The base station may configure the UE with a carrier aggregation (CA) configuration based on the UE capabilities, such as the band combination and corresponding baseband budget for the second RAT, and the interest indicator.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a warning message comprising a first indication of a priority of the warning message and a second indication that identifies an event. The UE may transmit a repetition of the warning message based at least in part on the first indication. Numerous other aspects are described.
