Configuring unicast and broadcast communications for different radio access technologies

A method for wireless communications at a network device, comprising:

• receiving a user equipment (UE) capability report comprising:
• an indication of a UE capability of a UE, the UE capability comprising a band combination for a set of bands that comprises a first subset of bands for a first radio access technology and a second subset of bands for a second radio access technology, the indication of the UE capability indicating, for each band of the second subset of bands for the second radio access technology, support for one or more of broadcast communications or unicast communications, and the indication of the UE capability lacking an indication that the second subset of bands supports uplink communications, the lack of the indication that the second subset of bands supports the uplink communications informing the network device that the second subset of bands supports at least downlink broadcast transmissions, and
• an indication of a baseband budget value specific to the second radio access technology, the baseband budget value indicating baseband resources allocated for communicating using the second radio access technology;
• configuring the UE with a carrier aggregation configuration supporting the first radio access technology and the second radio access technology based at least in part on the band combination and the baseband budget value specific to the second radio access technology;
• and
• transmitting a broadcast transmission using the second radio access technology on one or more bands of the second subset of bands based at least in part on the second subset of bands supporting the downlink broadcast transmissions and the carrier aggregation configuration.

An apparatus for wireless communications at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit a UE capability report comprising:
• an indication of a UE capability for a band combination for a set of bands that comprises a first subset of bands for a first radio access technology and a second subset of bands for a second radio access technology, the indication of the UE capability indicating, for each band of the second subset of bands for the second radio access technology, support for one or more of broadcast communications or unicast communications, and the indication of the UE capability lacking an indication that the second subset of bands supports uplink communications, the lack of the indication that the second subset of bands supports the uplink communications informing a network device that the second subset of bands supports at least downlink broadcast transmissions, and
• an indication of a baseband budget value specific to the second radio access technology, the baseband budget value indicating baseband resources allocated for communicating using the second radio access technology;
• communicate using the first radio access technology on one or more bands of the first subset of bands based at least in part on the band combination;
• and
• receive a broadcast transmission using the second radio access technology on one or more bands of the second subset of bands based at least in part on the band combination, the second subset of bands supporting the downlink broadcast transmissions, and the baseband budget value specific to the second radio access technology.
