Slot indication for NR half-duplex FDD operation

An apparatus for wireless communication at a user equipment (UE) operating in a half duplex operation in a frequency division duplexing (FDD) mode, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive an indication of a slot pattern for a plurality of slots, wherein the slot pattern indicates the plurality of slots includes at least one flexible slot;
• receive a downlink control monitoring occasion configuration;
• monitor for downlink control from a base station based at least on the indication of the slot pattern and on the monitoring occasion configuration;
• determine whether the at least one flexible slot is an uplink slot or a downlink slot based on a downlink control information (DCI);
• and
• transmitting or receiving on the slot based on the determination.

A method of wireless communication at a base station communicating with a user equipment (UE) operating in a half duplex operation in a frequency division duplexing (FDD) mode, the method comprising:

• transmitting an indication of a slot pattern for a plurality of slots, wherein the slot pattern indicates the plurality of slots includes at least one flexible slot;
• transmitting downlink control to the UE based at least on the indication of the slot pattern;
• transmitting downlink control information (DCI) scheduling communication for the UE, wherein the DCI indicates that the at least one flexible slot is an uplink slot or a downlink slot;
• and
• transmitting or receiving communications on the slot based on the DCI indicating that the at least one flexible slot is the uplink slot or the downlink slot.
