Backscatter-based positioning

A method of wireless communication performed by a network entity, the method comprising:

• receiving a first measurement report from a first transmission/receiving point (TRP), the first measurement report indicates:
• first signal information for a first signal received by the first TRP from a reference device;
• and
• second signal information for a second signal received by the first TRP from a first tag device;
• receiving a second measurement report from a second TRP, the second measurement report indicates:
• third signal information for a third signal received by the second TRP from the reference device;
• and
• fourth signal information for a fourth signal received by the second TRP from the first tag device;
• and
• determining a position of the first tag device based on the second signal information, the fourth signal information, and a group delay adjustment, the group delay adjustment determined based on the first signal information and the third signal information.

A method for wireless communication performed by a first transmission/receiving point (TRP), the method comprising:

• receiving a TRP configuration from a network entity, the TRP configuration indicates a reference device and a tag device;
• receiving, from the reference device at a first time, a first signal;
• receiving, from a tag device at a second time, a second signal associated with a positioning session for the tag device;
• and
• transmitting, to the network entity and based on the TRP configuration, a first measurement report associated with the positioning session of the tag device, the first measurement report indicates:
• first signal information of the first signal, the first signal information based on the first time;
• and
• second signal information of the second signal, the second signal information based on the second time.
