Abstract: Disclosed are techniques for wireless communication. In an aspect, a location server may receive measurement reports from one or more receiving radio frequency identification (RFID) stations, the measurement reports being based on a backscattered signal from an RFID device observed at the one or more receiving RFID stations, and the backscattered signal being based on a positioning reference signal transmitted by a user equipment (UE). The location server may determine an estimated position of the RFID device based on the measurement reports.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may transmit feedback signaling for received sidelink messages to both the base station and the transmitting UE. The receiving UE may multicast a feedback message to both the base station and the transmitting UE on a physical uplink control channel (PUCCH) or on a physical sidelink feedback channel (PSFCH). The base station may configure the receiving UE with resources, the transmitting UE may allocate resources to the receiving UE, or the base station may actively monitor for the feedback message. In some examples, the receiving UE may operate in a dual connectivity mode, and may transmit the feedback message to both the base station and the transmitting UE on both the PUCCH and the PSFCH.

Abstract: Aspects presented herein may enable an entity that is receiving (or reading) reflected/backscattered signals from an IoT device to differentiate the reflected/backscattered signals from other reflections (e.g., noise or signals bounced from other objects). In one aspect, a wireless device transmits an indication of a positioning session to an IoT device, wherein the indication initiates the positioning session for the IoT device. The wireless device transmits, based on the positioning session, a set of PRSs to the IoT device via a plurality of transmission occasions. The wireless device receives, from the IoT device based on a reflection pattern, at least one PRS in the set of PRSs via at least one reception occasion.

Abstract: Positioning of one or more user equipments (UEs) is performed using broadcast common sounding reference signals (SRS) resources for positioning. The common SRS that is broadcast by a UE is received and measured by one or more base stations and one or more other UEs. The other UEs may have known positions and may server as anchor nodes for positioning. The other UEs may have known positions and may serve as a positioning (anchor) node or may have unknown positions and may be jointly positioned with the target UE. During joint positioning, each of the other UEs may similarly broadcast a common set of SRS that is received and measured by the base stations and other UEs for positioning. An angular measurement of the SRS broadcast by one or more UEs may be measured and used to resolve minor symmetry in positioning solutions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that one or more conditions are satisfied for preemption of a scheduled sidelink transmission. The UE may transmit a sidelink preemption indication that indicates that a set of resources associated with the scheduled sidelink transmission are to be preempted. The UE may use the set of resources for transmission or reception of another communication. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from each of multiple devices that communicate with the UE via one or more sidelink channels, information indicating a buffer status of the device. The UE may transmit, to a base station, a buffer status report that indicates a combined sidelink buffer status for the multiple devices. Numerous other aspects are described.

Abstract: Disclosed are systems and techniques for wireless communications. In one example, a method for wireless communications performed at a first user equipment (UE) can include determining at least one active interference cancellation (AIC) area for protection during a sidelink communication. In some aspects, the method can include determining one or more frequency subcarriers associated with protection of the at least one AIC area during the sidelink communication, wherein transmission of the one or more frequency subcarriers is configured to reduce interference within the at least one AIC area.
