Techniques for low-band anchored high-band connections in wireless communications

A method for wireless communication, comprising:

• establishing a low-band connection with a user equipment (UE);
• transmitting configuration information for one or more high-band connections to the UE via the low-band connection;
• transmitting an activation command to the UE to activate one of the one or more high-band connections;
• and
• receiving an indication of a currently supported mode of the UE for the one or more high-band connections responsive to transmitting the activation command.

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• establish a low-band connection with a base station;
• receive, from the base station via the low-band connection, configuration information for one or more high-band connections;
• receive an activation command from the base station to activate one of the one or more high-band connections;
• determine a currently supported mode for an activated high-band connection based at least in part on one or more measurements or parameters associated with the one or more high-band connections;
• and
• transmit an indication to the base station of the currently supported mode for the activated high-band connection.
