Half-duplex operation in new radio systems

A method for wireless communication at a base station, comprising:

• transmitting, to a user equipment (UE), signaling that indicates a carrier aggregation configuration comprising a first carrier and a second carrier, wherein a numerology or symbol duration within a first slot of the first carrier is different from a numerology or symbol duration within a second slot of the second carrier;
• determining a capability of the UE to communicate on the first carrier and the second carrier;
• identifying a symbol period designated for simultaneous communications in a first link direction on resources of the first carrier and in a second link direction on resources of the second carrier;
• and
• communicating on resources of the first carrier or the second carrier during the symbol period based at least in part on the capability.

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

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• receive, from a base station, signaling that indicates a carrier aggregation configuration comprising a first carrier and a second carrier, wherein a numerology or symbol duration within a first slot of the first carrier is different from a numerology or symbol duration within a second slot of the second carrier;
• identify a symbol period designated for simultaneous communications in a first link direction on resources of the first carrier and in a second link direction on resources of the second carrier;
• and
• communicate on resources of the first carrier or the second carrier during the symbol period based at least in part on a capability of the UE.

• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• transmit, to a user equipment (UE), signaling that indicates a carrier aggregation configuration comprising a first cell and a second cell, wherein a numerology or symbol duration within a first slot of the first cell is different from a numerology or symbol duration within a second slot of the second cell;
• determine a capability of the UE to communicate on the first carrier and the second carrier;
• identify a symbol period designated for simultaneous communications in a first link direction on resources of the first cell and in a second link direction on resources of the second cell;
