Carrier switching and antenna switching for long term evolution and new radio dual connectivity

A method of wireless communication performed by a network entity, comprising:

• receiving information that identifies an antenna switching capability for dual connectivity of a user equipment (UE) that relates to a capability of the UE to switch an antenna for a plurality of bands that are included in a band combination supported by the UE,
• wherein at least a first band, of the plurality of bands, corresponds to a first radio access technology (RAT) and at least a second band, of the plurality of bands, corresponds to a second RAT, and
• wherein the information that identifies the antenna switching capability for the dual connectivity indicates whether the first band corresponding to the first RAT and the second band corresponding to the second RAT are associated with switching together from a first antenna to a second antenna;
• and
• communicating with the UE based at least in part on the antenna switching capability for the dual connectivity.

A user equipment (UE) for wireless communication, comprising:

• one or more memories;
• and
• one or more processors coupled to the one or more memories, the one or more processors configured to:
• determine information regarding an antenna switching capability for dual connectivity of the UE that relates to a capability of the UE to switch an antenna for a plurality of bands that are included in a band combination supported by the UE,
• wherein at least a first band, of the plurality of bands, corresponds to a first radio access technology (RAT) and at least a second band, of the plurality of bands, corresponds to a second RAT;
• and
• signal the information regarding the antenna switching capability for the dual connectivity to a network entity,
• wherein the information regarding the antenna switching capability for the dual connectivity indicates whether the first band corresponding to the first RAT and the second band corresponding to the second RAT are associated with switching together from a first antenna to a second antenna.
