Duplication avoidance schemes in passive ue data delivery

An apparatus for wireless communications at a first backscatter reading device, comprising:

• at least one processor;
• and
• memory coupled with the at least one processor, the memory storing instructions executable by the at least one processor to cause the first backscatter reading device to:
• receive control signaling indicating that the first backscatter reading device is to monitor for backscatter data from a plurality of passive user equipments (UEs);
• receive a plurality of backscatter data messages from one or more passive UEs based at least in part on receiving the control signaling;
• monitor for feedback signaling, from a network entity, corresponding to one or more of the plurality of backscatter data messages;
• and
• forward at least a first backscatter data message of the plurality of backscatter data messages to the network entity based at least in part on the monitoring.

A method for wireless communications at a first backscatter reading device, comprising:

• monitoring for backscatter data from a plurality of passive user equipments (UEs), one or more additional backscatter reading devices, or both;
• receiving, based at least in part on the monitoring, a first backscatter data message from a first passive UE of the plurality of passive UEs via a second backscatter reading device of the one or more additional backscatter reading devices;
• and
• relaying the first backscatter data message to a network entity.
