Uplink indication for full-duplex operation

A user equipment (UE) for wireless communication, 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 UE to:
• identify that the UE is operating in a network that supports full-duplex communications;
• store, at a buffer of the UE, a downlink communication received by the UE based during full-duplex operation, the downlink communication received over time or frequency resources;
• receive, from a network entity in the network and after storing the downlink communication at the buffer of the UE, an indication of a portion of the time or frequency resources in which an uplink communication to the network entity overlaps in time with the downlink communication, wherein the uplink communication and the downlink communication are scheduled via separate downlink control information messages;
• determine a quantity of symbols during which the uplink communication overlaps with the downlink communication based at least in part on the indication;
• and
• decode the downlink communication stored at the buffer based at least in part on receipt of the indication of the portion of the time or frequency resources and the quantity of symbols during which the uplink communication overlaps with the downlink communication.

A user equipment (UE) for wireless communication, comprising:

• means for identifying that the UE is operating in a network that supports full-duplex communications;
• means for storing, at a buffer of the UE, a downlink communication received by the UE during full-duplex operation, the downlink communication received over time or frequency resources;
• means for receiving, from a network entity in the network and after storing the downlink communication at the buffer of the UE, an indication of a portion of the time or frequency resources in which an uplink communication to the network entity overlaps in time with the downlink communication, wherein the uplink communication and the downlink communication are scheduled via separate downlink control information messages;
• means for determining a quantity of symbols during which the uplink communication overlaps with the downlink communication based at least in part on the indication;
• and
• means for decoding the downlink communication stored at the buffer based at least in part on receipt of the indication of the portion of the time or frequency resources and the quantity of symbols during which the uplink communication overlaps with the downlink communication.

A non-transitory computer-readable medium storing code for wireless communication at a user equipment (UE), the code comprising instructions executable by a processor to:

• identify that the UE is operating in a network that supports full-duplex communications;
• store, at a buffer of the UE, a downlink communication received by the UE during full-duplex operation, the downlink communication received over time or frequency resources;
• receive, from a network entity in the network and after storing the downlink communication at the buffer of the UE, an indication of a portion of the time or frequency resources in which an uplink communication to the network entity overlaps in time with the downlink communication, wherein the uplink communication and the downlink communication are scheduled via separate downlink control information messages;
• determining a quantity of symbols during which the uplink communication overlaps with the downlink communication based at least in part on the indication;
• and
• decode the downlink communication stored at the buffer based at least in part on receipt of the indication of the portion of the time or frequency resources and the quantity of symbols during which the uplink communication overlaps with the downlink communication.
