Abstract: This disclosure provides systems, methods, and devices for wireless communication that support enhanced positioning operations using a repeater. In a first aspect, a method of wireless communication includes receiving, by the UE, an instruction from a base station (BS) to perform a first signal measurement at a first time and a second signal measurement at a second time; determining, by the UE and based on the instruction, a first signal characteristic of a first signal during the first time corresponding to a time when a first repeater is repeating the first signal from a base station; determining, by the UE and based on the instruction, a second signal characteristic of a second signal during the second time corresponding to a time when the first repeater is not repeating the second signal; and a location of the UE is determined based on the first signal characteristic and the second signal characteristic.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support a velocity estimation, such as a velocity estimation with radio frequency (RF) sensing. In a first aspect, a velocity of an object is determined based on doppler measurements from multiple transmission/reception points (TRPs). In a second aspect, the velocity of the object is determined based on angle of arrival (AoA) information received from multiple TRPs. The AoA information may include a range, an AoA, a time, or a combination thereof. In a third aspect, the velocity of the object is determined based on an orientation of the object during a sensing operation performed by a TRP. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support backscatter-based positioning. In a first aspect, a method of wireless communication includes transmitting a tag configuration message that indicates a first tag configuration and a second tag configuration. The method also includes transmitting a positioning reference signal (PRS). The method also includes receiving, from a first tag device, a first backscatter signal based on the PRS, and receiving, from a second tag device, a second backscatter signal based on the PRS. The method includes transmitting a measurement report that indicates a first round trip time (RTT) of the first tag device, and a second RTT of the second tag device. The first RTT is based on the first tag configuration and the first backscatter signal, and the second RTT is based on the second tag configuration and the second backscatter signal.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support backscatter-based positioning. In a first aspect, a method of wireless communication includes receiving multiple measurement reports associated with a tag device. The multiple measurement reports includes, for each transmission/reception point (TRP) of a group of TRPs, a measurement report of the TRP. The method also includes determining a position of the tag device based on the multiple measurement reports and a tag delay of the tag device. Other aspects and features are also claimed and described.
