HALF DUPLEX FDD USER EQUIPMENT OPERATION

Abstract:

A configuration to enable a UE to determine a slot direction for communication with a base station while operating in half duplex FDD with carrier aggregation. The apparatus receives a first indication of a slot pattern for a plurality of slots associated with at least one component carrier assigned to the UE, wherein the first indication indicates that each of the plurality of slots is one of an uplink slot, a downlink slot, a special slot, or a flexible slot, and the plurality of slots includes a flexible slot. The apparatus receives, from the base station, a second indication indicating whether the flexible slot is the uplink slot or the downlink slot. The apparatus communicates with a base station based on at least one of the first indication or the second indication.
