Techniques for signaling a panel switching capability of a user equipment

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

• one or more processors;
• memory coupled with the one or more processors;
• and
• instructions stored in the memory and executable by the one or more processors to cause the apparatus to:
• identify, as a UE capability, a maximum quantity of antenna panel switches that the UE performs per slot per frequency range for a set of multiple frequency ranges and per subcarrier spacing for a set of multiple subcarrier spacings;
• transmit, to a network device, a control message that includes an indication of the UE capability, wherein to indicate the UE capability the control message includes an information element that indicates the maximum quantity of antenna panel switches per slot per frequency range for the set of multiple frequency ranges and per subcarrier spacing for the set of multiple subcarrier spacings;
• and
• communicate within a frequency range of the set of multiple frequency ranges having a subcarrier spacing of the set of multiple subcarrier spacings with the network device via one or more antenna panels of the UE while satisfying the maximum quantity of antenna panel switches per slot for the frequency range and the subcarrier spacing indicated by the UE capability.
